Description

具有陶纖濾管之粒狀物與一氧化二氮一體去除裝置 Device for integrally removing particulate matter and nitrous oxide with ceramic fiber filter tube

本發明是有關於一種去除裝置，特別是指一種具有陶纖濾管之粒狀物與一氧化二氮一體去除裝置。 The invention relates to a removal device, in particular to an integrated removal device for particulate matter with ceramic fiber filter tubes and nitrous oxide.

參閱圖1，一種習知汙泥焚化及空氣污染防制裝置，包括：一設有一汙泥進料器12的燃燒爐11；一第一熱交換器13，連接該燃燒爐11；一陶纖過濾器14，連接該第一熱交換器13；一第二熱交換器15，連接該陶纖過濾器41；及一洗滌塔16，連接該第二熱交換器15。 Referring to FIG. 1, a conventional sludge incineration and air pollution prevention device includes: a combustion furnace 11 provided with a sludge feeder 12; a first heat exchanger 13 connected to the combustion furnace 11; and a ceramic fiber The filter 14 is connected to the first heat exchanger 13; a second heat exchanger 15 is connected to the ceramic fiber filter 41; and a washing tower 16 is connected to the second heat exchanger 15.

該汙泥進料器12用以將工業廢水、民生廢水處理後產生之脫水汙泥導入該燃燒爐11之中。 The sludge feeder 12 is used to introduce the dehydrated sludge generated after the treatment of industrial wastewater and domestic wastewater into the combustion furnace 11.

該燃燒爐1用以焚化脫水汙泥，並經由一第一排氣管W1連通該第一熱交換器2，使燃燒廢氣經由該第一排氣管W1進入該第一熱交換器13。 The combustion furnace 1 is used to incinerate dehydrated sludge, and communicates with the first heat exchanger 2 through a first exhaust pipe W1, so that the combustion exhaust gas enters the first heat exchanger 13 through the first exhaust pipe W1.

該第一熱交換器13設有一第一風扇F1及一進氣管131，該進氣管131於該第一熱交換器13之內與該第一排氣管W1不相連 通。藉由該第一風扇F1，將外界空氣導入該第一熱交換器13中，使該燃燒爐11所排出之燃燒廢氣降溫，同時預熱即將進入該燃燒爐11之空氣。繼而，經由該進氣管131將預熱之空氣導入該燃燒爐11之中，以促進該燃燒爐11之燃燒作用。於該第一熱交換器13中，燃燒廢氣可以大幅降溫，以使燃燒廢氣可在適當之溫度下進入該陶纖過濾器14，達成良好之過濾效果，同時避免對該陶纖過濾器14造成傷害。 The first heat exchanger 13 is provided with a first fan F1 and an intake pipe 131, the intake pipe 131 is not connected to the first exhaust pipe W1 in the first heat exchanger 13 through. The first fan F1 guides the outside air into the first heat exchanger 13 to cool the combustion exhaust gas discharged from the combustion furnace 11 while preheating the air that is about to enter the combustion furnace 11. Then, the preheated air is introduced into the combustion furnace 11 through the intake pipe 131 to promote the combustion effect of the combustion furnace 11. In the first heat exchanger 13, the combustion exhaust gas can be greatly reduced in temperature, so that the combustion exhaust gas can enter the ceramic fiber filter 14 at an appropriate temperature to achieve a good filtering effect, while avoiding the ceramic fiber filter 14 hurt.

該第一熱交換器13經由一第二排氣管W2連接該陶纖過濾器14，以將燃燒廢氣導入該陶纖過濾器14中。該陶纖過濾器14是以陶瓷纖維製成，可用以進行燃燒廢氣之過濾，分離並收集燃燒廢氣中之飛灰。 The first heat exchanger 13 is connected to the ceramic fiber filter 14 via a second exhaust pipe W2 to introduce combustion exhaust gas into the ceramic fiber filter 14. The ceramic fiber filter 14 is made of ceramic fibers, and can be used for filtering combustion exhaust gas, separating and collecting fly ash in the combustion exhaust gas.

該陶纖過濾器14經由一第三排氣管W3連接該第二熱交換器15，以將燃燒廢氣導入該第二熱交換器15中。該第二熱交換器15設有一第二風扇F2及一供氣管151。該供氣管151於該第二熱交換器5內與該第三排氣管W3不相連通。藉由該第二風扇F2，將外界空氣導入該第二熱交換器15中，同時預熱進入該洗滌塔16頂端之煙囪161的空氣，繼而，經由該供氣管151導入該洗滌塔16頂端之煙囪161中。於該第二熱交換器15中，燃燒廢氣會降溫至約250~300℃，而後再進入該洗滌塔16中，以避免產生可見之白煙自該煙囪161之頂部排出。 The ceramic fiber filter 14 is connected to the second heat exchanger 15 via a third exhaust pipe W3 to introduce combustion exhaust gas into the second heat exchanger 15. The second heat exchanger 15 is provided with a second fan F2 and an air supply pipe 151. The air supply pipe 151 is not in communication with the third exhaust pipe W3 in the second heat exchanger 5. By the second fan F2, the outside air is introduced into the second heat exchanger 15 while preheating the air entering the chimney 161 at the top of the scrubber 16, and then introduced into the top of the scrubber 16 through the air supply pipe 151 Chimney 161. In the second heat exchanger 15, the combustion exhaust gas will cool down to about 250-300° C., and then enter the scrubber 16 to avoid the generation of visible white smoke from the top of the chimney 161.

該第二熱交換器15經由一第四排氣管W4連接該洗滌塔16，以將燃燒廢氣導入該洗滌塔16中。該洗滌塔16設有一第三風扇F3，藉以促進燃燒廢氣自該燃燒爐11向該洗滌塔16流動。該洗滌塔16用以中和並吸收燃燒廢氣中的酸性物質。燃燒廢氣經過該洗滌塔16後，會降溫至大約40℃，再藉由該第三風扇F3之幫助，自該洗滌塔16之頂部煙囪161排出。 The second heat exchanger 15 is connected to the washing tower 16 via a fourth exhaust pipe W4 to introduce combustion exhaust gas into the washing tower 16. The scrubber 16 is provided with a third fan F3 to promote the flow of combustion exhaust gas from the combustion furnace 11 to the scrubber 16. The scrubber 16 is used to neutralize and absorb acidic substances in the combustion exhaust gas. After passing through the scrubber 16, the combustion exhaust gas will cool down to about 40°C, and then be discharged from the chimney 161 at the top of the scrubber 16 with the help of the third fan F3.

然而，上述圖1所示的習知汙泥焚化及空氣污染防制裝置並無法處理包括一氧化二氮(N2O，俗稱笑氣)的廢氣。另外，由於該陶纖過濾器14中的陶纖濾管之觸媒並無法耐高溫，故才需要在該陶纖過濾器14之上游處設置該第一熱交換器13，因而上述習知汙泥焚化及空氣污染防制裝置需設置第一熱交換器13及第二熱交換器15等兩套熱交換器，導致設備建置成本高昂。故，有必要尋求解決之道。 However, the conventional sludge incineration and air pollution prevention device shown in FIG. 1 above cannot process exhaust gas including nitrous oxide (N 2 O, commonly known as laughing gas). In addition, since the catalyst of the ceramic fiber filter tube in the ceramic fiber filter 14 cannot withstand high temperature, it is necessary to install the first heat exchanger 13 upstream of the ceramic fiber filter 14, so the above-mentioned conventional pollution The sludge incineration and air pollution prevention device needs to be equipped with two sets of heat exchangers such as the first heat exchanger 13 and the second heat exchanger 15, which results in high equipment installation costs. Therefore, it is necessary to seek a solution.

因此，本發明之目的，即在提供一種具有陶纖濾管之粒狀物與一氧化二氮一體去除裝置。 Therefore, the object of the present invention is to provide an integrated removal device for particulate matter with ceramic fiber filter tubes and nitrous oxide.
