Description

Technical Field

[0001] The utility model relates to waste gas treatment equipment, in particular to energy-saving and environment-friendly chemical waste gas spraying equipment. Background Art

[0002] At present, the common treatment methods for chemical waste gas mainly include: immersion and spraying. The immersion type is to directly pass the waste gas into the absorption liquid. In this method, the contact area between the waste gas and the liquid is small, and the waste gas overflows in the form of bubbles before it can be absorbed. The absorption efficiency of the waste gas is low; the spraying type is to use water flow to spray the waste gas. In actual use, the spraying equipment needs to work all the time, resulting in a large amount of water resources. Regarding the treatment methods of chemical waste gas, both the immersion type and the spraying type have certain defects, such as low waste gas treatment efficiency or serious waste of water resources. For this reason, we have designed an energy-saving and environmentally friendly chemical waste gas spraying equipment to solve the above problems. Utility Model Content

[0021] Based on the above-mentioned structural setting, the energy-saving and environmentally friendly chemical waste gas spraying equipment is composed of a flushing tower 100, a waste gas pipeline 200 and a waste gas treatment component 300. Specifically, during the working process, the waste gas is input into the air distribution pipe 210 from the air inlet pipe 220, and is output by a plurality of aeration heads 230 respectively, so that the waste gas enters the flushing tower 100, and the absorption liquid is input into the liquid distribution pipe 3310 from the first liquid inlet pipe 3320, and is sprayed out by a plurality of nozzles 3330 respectively, so that the absorption liquid is sprayed in the flushing tower 100, and the rising waste gas contacts with the sprayed absorption liquid and is absorbed by the absorption liquid, and the sprayed absorption liquid finally falls on the bottom of the flushing tower 100 and converges into a flow, gradually covering the waste gas pipeline 200, and the waste gas subsequently output by the waste gas pipeline 200 will first contact with the absorption liquid converged at the bottom of the flushing tower 100, and will overflow due to insufficient contact. The exhaust gas discharged will further contact with the sprayed absorption liquid. The treated exhaust gas is further filtered through the filter medium 320 and finally discharged from the exhaust pipe 600. The energy-saving and environmentally friendly chemical waste gas spraying equipment combines the immersion type and spray type waste gas treatment methods. A waste gas treatment component 300 and a waste gas pipeline 200 are respectively provided at the top and bottom of the flushing tower 100. In the waste gas treatment component 300, a support bucket 310 and a spray pipe 330 are provided. The support bucket 310 with a cone structure can guide the rising exhaust gas to ensure that the exhaust gas is in full contact with the absorption liquid sprayed from the spray pipe 330. The spray liquid will eventually gather at the bottom of the flushing tower 100 and gradually cover the exhaust pipe 200, so that the exhaust gas input from the subsequent exhaust pipe 200 is first treated by immersion and then by spraying, which greatly improves the treatment effect of the exhaust gas.

[0022] Furthermore, the flushing tower 100 is erected on the ground in a vertical direction through a frame 400. The flushing tower 100 includes a sealing plate 110, a sleeve 120 and a tank body 130 coaxially distributed from top to bottom, and the sealing plate 110 and the tank body 130 are respectively assembled with the top and bottom flanges of the sleeve 120. Among them, since the exhaust gas treatment component 300 is installed in the flushing tower 100 in an embedded manner, it is preferred to split the flushing tower 100 into the sealing plate 110, the sleeve 120 and the tank body 130, so as to realize the convenient disassembly and assembly of the flushing tower 100, which is conducive to the quick disassembly and assembly of the exhaust gas treatment component 300.

[0023] Furthermore, the outer periphery of the top of the supporting bucket 310 is provided with two concentrically distributed first enclosures 3110, and two annular grooves are formed between the two first enclosures 3110 and on the top and bottom surfaces of the flange edge of the supporting bucket 310, and both are embedded with first rubber pads 3120. Among them, the supporting bucket 310 is embedded between the sleeve 120 and the tank body 130 through the flange edge of its top. Preferably, by providing two first enclosures 3110 on the flange edge of the supporting bucket 310, annular grooves are formed on the top and bottom surfaces of the flange edge between the two first enclosures 3110 for embedding the flange edge of the bottom and the top of the sleeve 120, respectively, and the two first rubber pads 3120 are used to ensure the reliable and stable installation of the supporting bucket 310, and ensure the sealing of the flange connection between the sleeve 120 and the tank body 130.

[0024] Furthermore, two concentrically distributed second enclosures 1110 are provided on the outer side of the bottom of the sealing plate 110, and an annular groove is formed between the two second enclosures 1110 and on the bottom surface of the sealing plate 110, and a second rubber pad 1120 is embedded. Among them, the two second enclosures 1110 provided at the bottom of the sealing plate 110 have the same function as the above-mentioned first enclosure 3110, and an annular groove is formed between the two second enclosures 1110 on the bottom surface of the sealing plate 110 for the top flange edge of the sleeve 120 to be embedded, and the second rubber pad 1120 is used to ensure the secure and stable installation of the sealing plate 110, and ensure the sealing of the flange connection between the sealing plate 110 and the sleeve 120.

[0025] Furthermore, the outer end of the air inlet pipe 220 passes through the flushing tower 100 and a first one-way valve 240 is installed on the pipe. When the sprayed absorption liquid converges at the bottom of the flushing tower 100 and covers the top of the aeration head 230, if the aeration head 230 is damaged, the absorption liquid converged at the bottom of the flushing tower 100 will flow back into the air inlet pipe 220. Preferably, in order to prevent the absorption liquid from flowing into the air inlet pipe 220, a first one-way valve 240 is installed on the air inlet pipe 200.

[0026] Furthermore, it also includes a second liquid inlet pipe 3340 which is centrally symmetrically distributed with respect to the axis of the liquid distribution pipe 3310 and the first liquid inlet pipe 3320. Both the first liquid inlet pipe 3320 and the second liquid inlet pipe 3340 penetrate the flushing tower 100 and are respectively equipped with two second one-way valves 3350. Among them, a plurality of nozzles 3330 cooperate with the liquid distribution pipe 3310 in an annular structure to be embedded in the periphery of the inner side of the flushing tower 100. Preferably, the second liquid inlet pipe 3340 is connected to the side of the liquid distribution pipe 3310 away from the first liquid inlet pipe 3320. After the operation is completed, water flow can be supplied into the second liquid inlet pipe 3340 to perform a flushing operation on the inner wall of the flushing tower 100. The first liquid inlet pipe 3320 and the second liquid inlet pipe 3340 cannot be opened synchronously. The setting of the second one-way valve 3350 ensures that when the absorption liquid and the water flow are supplied separately, they can be output by the nozzle 3330 and do not affect each other.
