Description

Various waste liquid mixing and regulating systems and waste liquid combustion systems

The present invention relates to the field of incineration treatment technology, and in particular to a multi-waste liquid mixing and regulating system and a waste liquid combustion system.

Generally, waste liquids on the market include solvents, waste engine oil, cutting oil, etc., and the calorific values of these waste liquids are different. In the current incinerator treatment system, when the calorific values of waste liquids are different, most of the waste liquids are burned by choosing a single item. Since different waste liquids have different calorific values, they will also produce different temperatures when burned. Therefore, when the calorific value of the waste liquid is high, water is injected during combustion to reduce the temperature of the combustion tank. When the calorific value of the waste liquid is low, fuel (such as natural gas, diesel, etc.) is added to assist ignition and maintain combustion to maintain the temperature of the combustion tank during the incineration process. The above approach requires additional additives, which makes it difficult to control the temperature of the incinerator and may consume a large amount of auxiliary fuel, resulting in high energy consumption. In addition, when waste liquid is burned, due to the different characteristics of each type of waste liquid, gaseous products, fly ash and bottom ash will be produced during the treatment process. These fly ash and bottom ash may contain high concentrations of harmful substances. The energy recovery efficiency of waste liquid incineration is relatively low, and the effect of conversion into energy utilization is not good.

Therefore, the present invention aims at the above-mentioned problems of the prior art and further proposes a multiple waste liquid mixing and regulating system and a waste liquid combustion system to solve the problems arising from the prior art.

In view of the above problems, the main purpose of the present invention is to provide a variety of waste liquid mixing and regulating system and waste liquid combustion system for mixing different waste liquids to improve the optimal efficiency of incinerator combustion of waste liquids, and through the present invention, the effects of automatic operation, mixing of waste liquids and automatic combustion can be achieved.

To achieve the above-mentioned purpose, the present invention provides a multi-type waste liquid mixing and regulating system, which is applied to an incinerator. The multi-type waste liquid mixing and regulating system includes a plurality of storage tanks, a plurality of mixing tanks, a plurality of spray gun groups and a control processor. The plurality of storage tanks respectively contain different waste liquids, and each has calorific value data of the corresponding waste liquid. The plurality of mixing tanks are respectively connected to each storage tank, and the plurality of mixing tanks obtain the waste liquid output by the plurality of storage tanks and mix them to form mixed waste liquid. The plurality of spray gun groups are respectively connected to the plurality of mixing tanks, and the mixed waste liquid of each mixing tank is sprayed into the incinerator through the spray gun group. The control processor is connected to a plurality of storage tanks, a plurality of mixing tanks and a plurality of spray gun groups. The control processor calculates a preset fuel supply calorific value according to a combustion calorific value requirement and a total mixed amount in the incinerator, and reads the calorific value data of the plurality of storage tanks and calculates an output ratio and an output metering of each storage tank; the control processor controls the plurality of storage tanks to output waste liquid to the plurality of mixing tanks according to the output ratio and the output metering, and controls the plurality of spray gun groups to spray an output flow rate of the mixed waste liquid, so as to adjust the spray flow rate of the mixed waste liquid.

According to the above purpose, the present invention further provides a waste liquid combustion system, which includes an incinerator, a temperature sensor and the aforementioned multiple waste liquid mixing and regulating system.

The present invention can also achieve the effects of automatic operation, mixing of waste liquids and automatic combustion.

The embodiments of the present invention will be further explained below in conjunction with the relevant drawings. As much as possible, the same reference numerals in the drawings and the specification represent the same or similar components. In the drawings, the shapes and thicknesses may be exaggerated for the sake of simplicity and convenience. It is understood that the components not specifically shown in the drawings or described in the specification are the forms known to those with ordinary knowledge in the relevant technical field. Those with ordinary knowledge in this field can make various changes and modifications based on the content of the present invention.

The following is an example of a multiple waste liquid mixing and regulating system of the present invention, which can be applied to an incinerator. Referring to FIG1 , the multiple waste liquid mixing and regulating system 10 includes a plurality of storage tanks 110, a plurality of mixing tanks 120, a plurality of spray gun assemblies 130, and a control processor 140. The block diagram of FIG1 does not show the plurality of storage tanks 110, the plurality of mixing tanks 120, the plurality of spray gun assemblies 130, etc. for the sake of simplicity, but a person with ordinary knowledge should understand that the number of the above-mentioned components is a plurality through the following description. The plurality of storage tanks 110 respectively contain different waste liquids, and each has the calorific value data of the corresponding waste liquid. A plurality of mixing tanks 120 are respectively connected to each storage tank 110, and the plurality of mixing tanks 120 obtain the waste liquid outputted by the plurality of storage tanks 110 and mix them to form mixed waste liquid. A plurality of spray gun assemblies 130 are respectively connected to the plurality of mixing tanks 120, and the mixed waste liquid of each mixing tank 120 is sprayed to the incinerator through the spray gun assemblies 130. The control processor 140 is connected to the plurality of storage tanks 110, the plurality of mixing tanks 120 and the plurality of spray gun assemblies 130. The control processor 140 calculates the preset fuel supply calorific value according to the combustion calorific value requirement and the total mixed amount in the incinerator, and reads the calorific value data of the plurality of storage tanks 110 and calculates the output ratio and output metering of each storage tank 110. The control processor 140 controls the plurality of storage tanks 110 to output the waste liquid to the plurality of mixing tanks 120 according to the output ratio and the output metering, and controls the output flow rate of the plurality of spray gun assemblies 130 to spray the mixed waste liquid, so as to adjust the spray flow rate of the mixed waste liquid.

In order to more clearly understand the characteristics of each component in the multi-waste liquid mixing and regulating system 10, please refer to FIG. 1 and FIG. 2 and FIG. 3 for the following description.

As shown in FIG. 1 and FIG. 2 , the storage tank 110 is provided with a storage liquid agitator 1102, a waste liquid inlet 1103 and a waste liquid outlet 1104. The waste liquid inlet 1103 is located at the upper part of each storage tank 110 and is used to receive the waste liquid input by the tank truck 50. The waste liquid outlet 1104 is located at the lower part of each storage tank 110 and is connected to a plurality of mixing tanks 120. The storage liquid agitator 1102 is located inside each storage tank 110 and is used to stir the waste liquid, and the waste liquid is output to the plurality of mixing tanks 120 through the waste liquid outlet 1104.

The tank truck 50 mentioned above is loaded with waste liquid. Generally, before entering the workplace and preparing to output the waste liquid, it will be connected to the multi-type waste liquid mixing and regulating system 10 of the present invention (for example, signal connection). The multi-type waste liquid mixing and regulating system 10 reads the weighing data of the tank truck 50, scans the barcode of the tank truck 50, and automatically generates a batch number. Regardless of whether the work manager manually inputs the information or the tank truck 50 has built-in information, the control processor 140 will receive all the information of the batch of waste liquid, including the type and calorific value data of the waste liquid. After the control processor 140 receives the type and calorific value data of the waste liquid, the control processor 140 determines which storage tank 110 the batch of waste liquid will be input into according to the preset waste liquid classification.

Since some waste liquids will produce chemical reactions when mixed, they cannot be mixed randomly. A small amount of compatibility test must be conducted first, and then the control processor 140 calculates and adjusts the preset combustion calorific value according to the calorific value data of various waste liquids and the current combustion requirements, and then executes the subsequent waste liquid mixing steps.

As shown in FIG. 1 and FIG. 3 , the mixing tank 120 is provided with a mixing agitator 1202 and a mixed waste liquid outlet 1204. The mixed waste liquid outlet 1204 is located at the bottom of each mixing tank 120 and is connected to the spray gun assembly 130 through a pipeline. The mixing agitator 1202 is located inside each mixing tank 120 and is used to stir the mixed waste liquid. The mixed waste liquid is output to the spray gun assembly 130 through the mixed waste liquid outlet 1204. The spray gun assembly 130 usually includes at least two spray guns (spray gun a1, spray gun a2) to facilitate the sprayed mixed waste liquid to be uniformly input into the incinerator, improve the uniformity of combustion, and avoid inconsistent temperature in the furnace.

The spray gun assembly 130 is a two-fluid spray gun assembly, which can further atomize the waste liquid and refine the droplet size, thereby making the waste liquid gasified instantly when sprayed into the incinerator, so that the organic matter can be oxidized and decomposed efficiently. Therefore, various waste liquids of the present invention can be mixed and sprayed according to needs, or they can be sprayed independently.

As shown in FIG. 2 and FIG. 3 , the waste liquid output port 1104 of FIG. 2 is connected to the mixing tank 120 of FIG. 3 , and a waste liquid output pipeline 1106 is provided between the waste liquid output port 1104 and the mixing tank 120.
