在本發明的一實施例中，上述的流體儲存槽儲存的流體為二氧化碳，氣固態混合物產生器的混合物為氣態與固態的二氧化碳，混拌槽為混凝土混拌槽。In one embodiment of the present invention, the fluid stored in the fluid storage tank is carbon dioxide, the mixture in the gas-solid mixture generator is gaseous and solid carbon dioxide, and the mixing tank is a concrete mixing tank.
基於上述，本發明的混拌裝置的氣固態混合物產生器連通至流體儲存槽，用以使流體儲存槽內的流體相變化為氣態與固態的混合物，且透過混合物管路輸送混合物至混拌槽。氣固態混合物產生器可使流體的一部分變為固體，而能夠更好地與混拌槽內的材料混合，而可提升混合效率。此外，本發明的混拌裝置的氣體回收槽連通於混合物管路，用以回收混合物中未通入混拌槽的氣體。廢水槽連通於氣體回收槽與混拌槽之間。因此，氣體回收槽所回收的氣體適於被導入廢水槽，而可與廢水槽內的廢水反應，且流至混拌槽，進一步地以液態的形式來與混拌槽內的材料混合，而可提升混合效率。另外，未與廢水槽內的廢水反應的氣體也流至混拌槽，增加與混拌槽內的材料混合的機率。Based on the above, the gas-solid mixture generator of the mixing device of the present invention is connected to a fluid storage tank to change the phase of the fluid in the fluid storage tank into a gas-solid mixture, and the mixture is transported to the mixing tank through a mixing pipeline.

In addition, the gas recovery tank of the mixing device of the present invention is connected to the mixing pipeline to recover the gas in the mixture that has not been introduced into the mixing tank.

In addition, gases that do not react with the wastewater in the wastewater tank also flow into the mixing tank, increasing the probability of mixing with the materials in the mixing tank.
圖1是依照本發明的一實施例的一種混拌裝置的示意圖。請參閱圖1，本實施例的混拌裝置100包括一流體儲存槽110、一氣固態混合物產生器120、一混合物管路125、一混拌槽130、一氣體回收槽140及一廢水槽150。Figure 1 is a schematic diagram of a mixing device according to an embodiment of the present invention. Referring to Figure 1, the mixing device 100 of the present embodiment includes a fluid storage tank 110, a gas-solid mixture generator 120, a mixture pipeline 125, a mixing tank 130, a gas recovery tank 140, and a wastewater tank 150.
流體儲存槽110用以儲存流體。在本實施例中，流體儲存槽110儲存的流體為二氧化碳，例如是液體的二氧化碳，但流體儲存槽110儲存的流體種類不以此為限制。The fluid storage tank 110 is used to store fluids. In this embodiment, the fluid stored in the fluid storage tank 110 is carbon dioxide, such as liquid carbon dioxide, but the type of fluid stored in the fluid storage tank 110 is not limited thereto.
在本實施例中，混拌裝置100更可選擇地包括一電磁閥160與一流量閥162，流量閥162設置於流體儲存槽110與氣固態混合物產生器120之間。電磁閥160設置於流體儲存槽110與流量閥162之間。當然，電磁閥160與流量閥162的設置位置不以此為限制。In this embodiment, the mixing device 100 may optionally include a solenoid valve 160 and a flow valve 162, with the flow valve 162 disposed between the fluid storage tank 110 and the gas-solid mixture generator 120. The solenoid valve 160 is disposed between the fluid storage tank 110 and the flow valve 162. Of course, the placement of the solenoid valve 160 and the flow valve 162 is not limited thereto.
電磁閥160用以控制流體儲存槽110內所儲存的流體是否能流至氣固態混合物產生器120。流量閥162用以控制流體儲存槽110內所儲存的流體流至氣固態混合物產生器120的流量，進而可控制氣固態混合物產生器120所產生的氣態與固態的混合物的流速。Solenoid valve 160 is used to control whether the fluid stored in fluid storage tank 110 can flow to gas-solid mixture generator 120. Flow valve 162 is used to control the flow rate of fluid stored in fluid storage tank 110 to gas-solid mixture generator 120, thereby controlling the flow rate of gaseous and solid mixture generated by gas-solid mixture generator 120.
氣固態混合物產生器120連通至流體儲存槽110，用以使流體儲存槽110內的流體相變化為氣態與固態的混合物。在本實施例中，氣固態混合物產生器120的混合物為氣態與固態的二氧化碳，但不以此為限制。The gas-solid mixture generator 120 is connected to the fluid storage tank 110 to change the phase of the fluid in the fluid storage tank 110 into a mixture of gaseous and solid states. In this embodiment, the mixture of the gas-solid mixture generator 120 is gaseous and solid carbon dioxide, but this is not a limitation.
混合物管路125連通於氣固態混合物產生器120，且混拌槽130連通至混合物管路125。氣態與固態的混合物適於透過混合物管路125輸送至混拌槽130。在本實施例中，氣固態混合物產生器120處的壓力大於混拌槽130內的壓力，因此，氣態與固態的混合物可自然地被輸送至混拌槽130。A mixing pipeline 125 is connected to a gas-solid mixture generator 120, and a mixing tank 130 is connected to the mixing pipeline 125. A gaseous and solid mixture is suitable for being transported to the mixing tank 130 via the mixing pipeline 125. In this embodiment, the pressure at the gas-solid mixture generator 120 is greater than the pressure inside the mixing tank 130; therefore, the gaseous and solid mixture can be naturally transported to the mixing tank 130.
在本實施例中，混拌槽130例如為混凝土混拌槽130。當然，在其他實施例中，混拌槽130也可容納其他要混拌的材料。混拌槽130內有混拌軸，用以混拌投入混拌槽130內的混凝土。氣態與固態的混合物送入混拌槽130內時，會與混凝土一起被混拌軸攪動混合，而在其後被固化在混凝土中。In this embodiment, the mixing tank 130 is, for example, a concrete mixing tank 130. Of course, in other embodiments, the mixing tank 130 may also accommodate other materials to be mixed. The mixing tank 130 contains a mixing shaft for mixing the concrete fed into the mixing tank 130. When the gaseous and solid mixture is fed into the mixing tank 130, it is stirred and mixed together with the concrete by the mixing shaft, and subsequently solidified in the concrete.
在本實施例中，由於氣固態混合物產生器120可使流體的一部分變為固體，相較於純氣態，具有固態的二氧化碳的混合物能夠更好地與混拌槽130內的混凝土混合，而可提升混合效率。In this embodiment, since the gas-solid mixture generator 120 can turn a portion of the fluid into a solid, the mixture containing solid carbon dioxide can mix better with the concrete in the mixing tank 130 than the pure gas, thereby improving the mixing efficiency.
此外，氣體回收槽140連通於混合物管路125，用以回收混合物中未通入混拌槽130的氣體。混拌裝置100更包括一氣體回收管路142，氣體回收管路142連通於混合物管路125與氣體回收槽140之間。氣體回收管路142可選擇地設有閥148，以控制氣體是否能流入氣體回收槽140。In addition, the gas recovery tank 140 is connected to the mixture pipeline 125 to recover gas in the mixture that is not introduced into the mixing tank 130. The mixing device 100 further includes a gas recovery pipeline 142, which connects the mixture pipeline 125 and the gas recovery tank 140. The gas recovery pipeline 142 may optionally be equipped with a valve 148 to control whether gas can flow into the gas recovery tank 140.
在本實施例中，混拌裝置100更可選擇地包括一第一泵146，設置於混合物管路125與氣體回收槽140之間，用以使氣體回收管路142形成壓降。如此一來，當閥148開啟時，混合物管路125內未通入混拌槽130的氣體可因壓降而自然地流向氣體回收槽140。當然，在其他實施例中，若混合物管路125內的混合物有足夠的壓力與速度，混拌裝置100也可以不設置第一泵146。In this embodiment, the mixing device 100 may optionally include a first pump 146 disposed between the mixing pipeline 125 and the gas recovery tank 140 to create a pressure drop in the gas recovery pipeline 142. Thus, when the valve 148 is opened, the gas in the mixing pipeline 125 that has not entered the mixing tank 130 can naturally flow to the gas recovery tank 140 due to the pressure drop. Of course, in other embodiments, if the mixture in the mixing pipeline 125 has sufficient pressure and velocity, the mixing device 100 may not require the first pump 146.
此外，在一實施例中，在一重力方向D上，混拌槽130位於混合物管路125的下方，且氣體回收槽140與氣體回收管路142位於混合物管路125的上方。這樣的設計可使得混合物管路125內的氣態與固態的混合物中較重的部分(也就是混合物中的固體)會與部分的氣體一起受到重力向下而流至混拌槽130內。混合物中未能進入混拌槽130的氣體自然地透過氣體回收管路142流向氣體回收槽140。也就是說，混拌裝置100也是可以透過高度差來設置這些槽體或管路，以使流動更為順暢，或可減少泵的設置而可降低成本。當然，配置上不一定需要透過高度差或是在管路上增加泵來設置。Furthermore, in one embodiment, in a gravitational direction D, the mixing tank 130 is located below the mixing pipeline 125, and the gas recovery tank 140 and the gas recovery pipeline 142 are located above the mixing pipeline 125. This design allows the heavier portion (i.e., the solids in the mixture) of the gaseous and solid mixture in the mixing pipeline 125 to flow downwards into the mixing tank 130 along with some of the gas due to gravity. Gas in the mixture that fails to enter the mixing tank 130 naturally flows to the gas recovery tank 140 through the gas recovery pipeline 142. That is to say, the mixing device 100 can also be configured with these tanks or pipelines by means of height difference to make the flow smoother, or to reduce the need for pumps and thus reduce costs. Of course, the configuration does not necessarily require the use of height difference or the addition of pumps to the pipeline.
在一實施例中，混拌裝置100更包括一濾網144。濾網144設置於氣體回收管路142與混合物管路125的交界處。由於混合物中的固體的尺寸較大，濾網144可避免固體通過，以確保混合物中固體的部分能夠向下進入混拌槽130，且避免混合物中固體的部分流至氣體回收槽140。In one embodiment, the mixing device 100 further includes a filter screen 144. The filter screen 144 is disposed at the junction of the gas recovery line 142 and the mixture line 125. Since the solids in the mixture are relatively large, the filter screen 144 can prevent the solids from passing through, so as to ensure that the solid portion of the mixture can enter the mixing tank 130 downwards and prevent the solid portion of the mixture from flowing into the gas recovery tank 140.
氣體回收槽140連通於廢水槽150。混拌裝置100更可選擇地包括一第一閥154，設置於氣體回收槽140與廢水槽150之間。第一閥154用以控制氣體回收槽140內的氣體是否能夠流向廢水槽150。The gas recovery tank 140 is connected to the wastewater tank 150. The mixing device 100 may optionally include a first valve 154 disposed between the gas recovery tank 140 and the wastewater tank 150. The first valve 154 is used to control whether the gas in the gas recovery tank 140 can flow to the wastewater tank 150.
在一實施例中，若氣體回收槽140內的氣壓大於廢水槽150內的氣壓，氣體回收槽140內的氣體可以自動地流向廢水槽150。在一實施例中，混拌裝置100更可選擇地包括一第二泵152，設置於氣體回收槽140與廢水槽150之間，以使被氣體回收槽140所回收的氣體能更快速地流向廢水槽150。In one embodiment, if the gas pressure in the gas recovery tank 140 is greater than the gas pressure in the wastewater tank 150, the gas in the gas recovery tank 140 can automatically flow to the wastewater tank 150. In another embodiment, the mixing device 100 may optionally include a second pump 152 disposed between the gas recovery tank 140 and the wastewater tank 150, so that the gas recovered by the gas recovery tank 140 can flow to the wastewater tank 150 more quickly.
氣體回收槽140所回收的氣體被導入廢水槽150之後，可與廢水槽150內的廢水進行礦化作用。礦化固碳技術是指二氧化碳的碳酸化反應，使二氧化碳轉換為碳酸鈣穩定的物質。因此，氣態二氧化碳在與廢水作用之後，便可反應成碳酸鈣混於廢水中。The gas recovered in the gas recovery tank 140 is introduced into the wastewater tank 150, where it can undergo a mineralization reaction with the wastewater. Mineralization and carbon sequestration technology refers to the carbonation reaction of carbon dioxide, converting it into calcium carbonate, a stable substance. Therefore, gaseous carbon dioxide reacts with wastewater to form calcium carbonate, which then mixes with the wastewater.
廢水槽150連通於氣體回收槽140與混拌槽130之間，礦化後的廢水會從廢水回收管路180流至混拌槽130。在一實施例中，廢水回收管路180可選擇地設有第三泵182，以使廢水回收管路180內的礦化後的廢水與未與廢水反應的氣體能更順利地流至混拌槽130。Wastewater tank 150 is connected between gas recovery tank 140 and mixing tank 130. The mineralized wastewater flows from wastewater recovery pipe 180 to mixing tank 130. In one embodiment, wastewater recovery pipe 180 may optionally be equipped with a third pump 182 to allow the mineralized wastewater and unreacted gas in wastewater recovery pipe 180 to flow more smoothly to mixing tank 130.
原本在製作混凝土時便會加水攪拌，本案利用此特性，以礦化後的廢水加入混拌槽130，除了可回收廢水，提升水資源的利用率之外，礦化後的廢水內的碳酸鈣在加入混拌槽130之後可與混凝土混合，並在之後與混凝土一起固化。Normally, water is added and mixed when making concrete. This project utilizes this characteristic by adding mineralized wastewater to the mixing tank 130. In addition to recycling the wastewater and improving the utilization rate of water resources, the calcium carbonate in the mineralized wastewater can be mixed with the concrete after being added to the mixing tank 130 and then solidified together with the concrete.
另外，未與廢水槽150內的廢水反應的氣體(二氧化碳)也會從廢水回收管路180流至混拌槽130，增加與混拌槽130內的材料(混凝土)混合的機率。如此一來，在混凝土製程之前所產生的二氧化碳可在混凝土製程中多次被回收，減少二氧化碳逸散至大氣的比率。In addition, gases (carbon dioxide) that do not react with the wastewater in the wastewater tank 150 will also flow from the wastewater recovery pipe 180 to the mixing tank 130, increasing the probability of mixing with the materials (concrete) in the mixing tank 130. In this way, carbon dioxide generated before the concrete production process can be recovered multiple times during the concrete production process, reducing the rate of carbon dioxide escaping into the atmosphere.
值得一提的是，在本實施例中，混拌裝置100更包括一再導入管路170。再導入管路170連通於氣體回收槽140與氣固態混合物產生器120之間，氣體回收槽140回收的一部分氣體可透過再導入管路170流至氣固態混合物產生器120，以再度透過氣固態混合物產生器120形成氣態與固態的二氧化碳，並進入混拌槽130，而與混拌槽130內的混凝土混合，而增加二氧化碳的回收率。It is worth mentioning that, in this embodiment, the mixing device 100 further includes a re-inlet pipe 170. The re-inlet pipe 170 is connected between the gas recovery tank 140 and the gas-solid mixture generator 120. A portion of the gas recovered by the gas recovery tank 140 can flow through the re-inlet pipe 170 to the gas-solid mixture generator 120, so as to re-form gaseous and solid carbon dioxide through the gas-solid mixture generator 120 and enter the mixing tank 130 to mix with the concrete in the mixing tank 130, thereby increasing the carbon dioxide recovery rate.
在一實施例中，第二閥172設置於再導入管路170，且再導入管路170可設有第四泵174。第四泵174用以加壓再導入管路170內的氣體，第二閥172與第四泵174的搭配，可使氣體回收槽140內的氣體能夠更順利地流至氣固態混合物產生器120。In one embodiment, a second valve 172 is disposed in a re-inlet line 170, and a fourth pump 174 may be provided in the re-inlet line 170. The fourth pump 174 is used to pressurize the gas in the re-inlet line 170. The combination of the second valve 172 and the fourth pump 174 allows the gas in the gas recovery tank 140 to flow more smoothly to the gas-solid mixture generator 120.
總體來說，混拌裝置100的流體儲存槽110內可儲存液態或是氣態二氧化碳，二氧化碳經電磁閥160及流量閥162流至氣固態混合物產生器120，一部分會形成雪花狀的固態二氧化碳，一部分會形成氣態二氧化碳。固態二氧化碳與部分的氣態二氧化碳流入混拌槽130內與混凝土混合。固態二氧化碳能有效增加與混凝土混合效果，氣態二氧化碳的一部分也能在與混凝土混合的過程中固化。因此，可使二氧化碳有效地被回收至混凝土內。In general, the fluid storage tank 110 of the mixing device 100 can store liquid or gaseous carbon dioxide. The carbon dioxide flows through the solenoid valve 160 and the flow valve 162 to the gas-solid mixture generator 120, where part of it forms snowflake-like solid carbon dioxide and part of it forms gaseous carbon dioxide. The solid carbon dioxide and part of the gaseous carbon dioxide flow into the mixing tank 130 to mix with the concrete. The solid carbon dioxide can effectively increase the mixing effect with the concrete, and part of the gaseous carbon dioxide can also solidify during the mixing process with the concrete. Therefore, carbon dioxide can be effectively recycled into the concrete.
未通入混拌槽130的氣態二氧化碳會被回收至氣體回收槽140內，氣體回收槽140內的一部分的氣態二氧化碳可透過再導入管路170回流至原先的二氧化碳供應管路，再度透過氣固態混合物產生器120產生氣態與固態的二氧化碳混合物，以再度進入混拌槽130與混凝土混合。另一方面，氣體回收槽140內的另一部分的氣態二氧化碳可被輸送至廢水槽150內與廢水進行礦化作用之後，再流入混拌槽130與混凝土混合。Gaseous carbon dioxide not introduced into the mixing tank 130 is recovered into the gas recovery tank 140. A portion of the gaseous carbon dioxide in the gas recovery tank 140 can flow back to the original carbon dioxide supply line through the reintroduction pipe 170, and then be re-generated into a mixture of gaseous and solid carbon dioxide through the gas-solid mixture generator 120, so as to re-enter the mixing tank 130 to mix with the concrete. On the other hand, another portion of the gaseous carbon dioxide in the gas recovery tank 140 can be transported to the wastewater tank 150 to undergo mineralization with the wastewater, and then flow into the mixing tank 130 to mix with the concrete.
因此，在混凝土製程之前所產生的二氧化碳，在混凝土製程中可被良好地回收，可減少二氧化碳逸散到大氣造成空氣汙染的狀況，且可達到二氧化碳回收再利用的效果。此外，經實測，與二氧化碳混合後的混凝土的抗壓強度提升，且收縮率下降，有效提升混凝土的性質。Therefore, the carbon dioxide generated before the concrete production process can be effectively recovered during the concrete production process, reducing the amount of carbon dioxide released into the atmosphere and causing air pollution, and achieving the effect of carbon dioxide recycling and reuse. In addition, actual tests have shown that concrete mixed with carbon dioxide has increased compressive strength and decreased shrinkage, effectively improving the properties of concrete.
綜上所述，本發明的混拌裝置的氣固態混合物產生器連通至流體儲存槽，用以使流體儲存槽內的流體相變化為氣態與固態的混合物，且透過混合物管路輸送混合物至混拌槽。氣固態混合物產生器可使流體的一部分變為固體，而能夠更好地與混拌槽內的材料混合，而可提升混合效率。此外，本發明的混拌裝置的氣體回收槽連通於混合物管路，用以回收混合物中未通入混拌槽的氣體。廢水槽連通於氣體回收槽與混拌槽之間。因此，氣體回收槽所回收的氣體適於被導入廢水槽，而可與廢水槽內的廢水反應，且流至混拌槽，進一步地以液態的形式來與混拌槽內的材料混合，而可提升混合效率。另外，未與廢水槽內的廢水反應的氣體也流至混拌槽，增加與混拌槽內的材料混合的機率。In summary, the gas-solid mixture generator of the mixing device of this invention is connected to a fluid storage tank to change the phase of the fluid in the fluid storage tank into a gas-solid mixture, which is then transported to the mixing tank through a mixing pipeline. The gas-solid mixture generator can convert a portion of the fluid into a solid, allowing for better mixing with the materials in the mixing tank and thus improving mixing efficiency. Furthermore, the gas recovery tank of the mixing device of this invention is connected to the mixing pipeline to recover any gas in the mixture that is not introduced into the mixing tank. A wastewater tank is connected between the gas recovery tank and the mixing tank. Therefore, the gas recovered by the gas recovery tank is suitable for being introduced into the wastewater tank, where it can react with the wastewater and flow to the mixing tank, where it is further mixed with the materials in the mixing tank in liquid form, thereby improving mixing efficiency. In addition, gases that do not react with the wastewater in the wastewater tank also flow into the mixing tank, increasing the probability of mixing with the materials in the mixing tank.
