Detailed implementation mode

[0020] This application discloses an exhaust gas odor elimination device. Please refer to Figure 1 , which includes a liquid reservoir 100, an inner cavity appliance 200, a spray pipe fitting 300, and a pumping pipeline 400. The inner cavity appliance 200 is opposite to the liquid reservoir 100. The spray pipe fitting 300 is installed on the inner cavity appliance 200, and the pumping pipeline 400 is connected between the liquid reservoir 100 and the spray pipe fitting 300.

[0021] The liquid reservoir 100 is used to hold the deodorant. When the device is in operation, the liquid reservoir 100 stores the deodorant. The deodorant is an existing material and can be purchased. The deodorant decomposes the organic matter in the waste gas and can also use its own fragrance function to cover up the odor of the waste gas.

[0022] The inner cavity appliance 200 can be in the form of a chimney, and the chimney belongs to the exhaust gas system. As Figure 1 shown, the inner cavity appliance 200 is provided with an air inlet 220 and an air outlet 230, and an inner cavity 210 communicating between the air inlet 220 and the air outlet 230. The air inlet 220 and the air outlet 230 are located at opposite ends of the inner cavity appliance 200. The waste gas to be treated enters the inner cavity 210 from the air inlet 220, and the waste gas with the odor treated is discharged from the air outlet 230. In the method of preparing protein feed by biological fermentation, protein feed is extracted through a spray drying tower, and hot air exhaust gas is discharged from the exhaust gas pipeline of the spray drying tower. The exhaust gas often has a pungent acidic odor and needs to be deeply treated. In some implementation modes, the air inlet 220 is used to communicate with the exhaust gas pipeline of the spray drying tower, and this device is used to treat the exhaust gas discharged from the exhaust gas pipeline of the spray drying tower.

[0023] Please refer to Figure 1 , each spray pipe fitting 300 is provided with a spray pipe 310 and an atomizing nozzle 320. The spray pipe 310 is installed on the inner cavity appliance 200. The spray pipe 310 penetrates through the inner cavity 210 of the inner cavity appliance 200. The atomizing nozzle 320 is installed on the spray pipe 310. At least one atomizing nozzle 320 is installed on the spray pipe 310. The atomizing nozzle 320 can be installed on the spray pipe 310 in a detachable connection manner, so as to facilitate the replacement and maintenance of the atomizing nozzle 320.

[0024] In the inner cavity 210 of the inner cavity appliance 200, the exhaust gas moves from the air inlet 220 along the inner cavity 210 towards the air outlet 230, and there is an air flow direction in the inner cavity 210. The spray pipe fittings 300 are arranged in at least two layers along the air flow direction of the inner cavity 210. Please refer to Figure 1 shows a scheme where the spray pipe fittings 300 are arranged in two layers along the air flow direction of the inner cavity 210. The number of layers of the spray pipe fittings 300 is limited to two or more, and each layer has a plurality of spray pipe fittings 300. Please refer to Figure 1 and Figure 2 , and the plurality of spray pipe fittings 300 belonging to each layer are evenly spaced along the circumferential direction of the inner cavity appliance 200, and the spray pipe fittings 300 of adjacent two layers are arranged staggeredly. For example, Figure 2 shows a schematic diagram of the staggered arrangement of the first-layer spray pipe fitting 331 and the second-layer spray pipe fitting 332 in

[0025] Please refer to Figure 1 , the pumping pipeline 400 is communicated with the liquid storage device 100, the pumping pipeline 400 is also communicated with the spray pipe 310, a main pump 411 is installed in the pumping pipeline 400, and the deodorant in the liquid storage device 100 is pumped to the spray pipe 310 through the pumping pipeline 400. The deodorant is sprayed from the atomizing nozzle 320 of the spray pipe 310 into the inner cavity 210 of the inner cavity appliance 200 in the form of water mist. The deodorant is sprayed in an atomized form into the exhaust gas to be treated flowing through the inner cavity appliance 200. Through the arrangement mode of the spray pipe fittings 300 in the inner cavity appliance 200, the deodorant is evenly sprayed onto the inner cavity 210 of the inner cavity appliance 200. This device ensures the uniformity of the deodorant spraying and minimizes the possibility of the appearance of spraying blind areas as much as possible. By decomposing the organic matter in the exhaust gas with the deodorant, the fragrance function of the deodorant itself can also be used to cover up the odor of the exhaust gas, effectively realizing the function of eliminating the odor of the exhaust gas.

[0026] In some embodiments, please refer to Figure 2 , the spray pipe fittings 300 are arranged in two layers along the air flow direction of the inner cavity 210. Each layer is provided with 4 spray pipe fittings 300 evenly spaced along the circumferential direction of the inner cavity appliance 200. The adjacent two spray pipe fittings on the circumferential direction of the inner cavity appliance 200 in each layer are spaced 90°. The spray pipe fittings 300 of adjacent two layers are arranged staggeredly by 45° on the circumferential direction of the inner cavity appliance 200. Figure 2 shows a schematic diagram of the 45° staggered arrangement of the first-layer spray pipe fitting 331 and the second-layer spray pipe fitting 332 in

[0027] In some embodiments, please refer to Figure 1 , at least two atomizing nozzles 320 are installed on the spray pipe 310 at intervals along the length direction, and all the spray pipe fittings 300 have the same specifications, which is convenient for management.

[0028] In some embodiments, please refer toFigure 1 The pumping pipeline 400 is installed with a standby pump 412 in parallel with the main pump 411. When the main pump 411 stops working, the standby pump 412 is adjusted to the working state so that the spray pipe fitting 300 continuously sprays the deodorant in the form of water mist, improving the working efficiency of the device for waste gas treatment.

[0029] In some embodiments, the main pump 411 and the standby pump 412 are metering pumps. The metering pump can maintain a constant flow rate independent of the discharge pressure and can simultaneously complete the functions of conveying, metering, and regulating, thereby simplifying the production process flow.

[0030] In some embodiments, the pumping pipeline 400 is installed with a pressure gauge 420. The pressure gauge 420 is used to detect the pipeline pressure of the pumping pipeline 400 during operation and to detect whether the pipeline pressure of the pumping pipeline 400 when conveying the deodorant is at the working pressure required.

[0031] In some embodiments, the pumping pipeline 400 is installed with a bladder type damper 430. The bladder type damper 430 buffers the fluctuations of the pumping pipeline 400 when conveying the deodorant, maintains the pipeline pressure of the pumping pipeline 400 when conveying the deodorant, makes the pipeline pressure of the pumping pipeline 400 constant when conveying the deodorant, thereby improving the stability of the deodorant sprayed by the spray pipe fitting 300 and making the spraying effect stable.

[0032] In some embodiments, the liquid storage device 100 is installed with a stirring member 110 and a motor 120. The motor 120 drives the stirring member 110, and by driving the stirring member 110 to rotate through the motor 120, the uniformity of the deodorant in the liquid storage device 100 is improved, so that the treatment effect of the deodorant on the waste gas in the inner cavity 210 of the inner cavity appliance 200 is maintained stable.
