[0002] Industrial waste gas refers to the general term for various pollutant-containing gases discharged into the air during fuel combustion and production processes in industrial plants. These waste gases include carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist), lead, mercury, beryllium compounds, soot, and production dust. When discharged into the atmosphere, they will pollute the air. These substances enter the human body through different respiratory tracts. Some directly cause harm, and some have an accumulation effect, which will more seriously harm human health. Different substances will have different effects. Therefore, purification equipment is needed to purify the industrial waste gas to be discharged to reduce the pollution caused by the discharged industrial waste gas to the external environment. Most of the purification devices for industrial waste gas treatment in the prior art use the method of filtration purification to purify the waste gas.

[0022] Such as Figures 1 to 7As shown, it shows a purification device for industrial waste gas treatment in an embodiment of the present disclosure, including a support base 1 and a purification box 2. The purification box 2 is installed on the upper side of the support base 1. It also includes a spraying member, a drying chamber 201, a lower housing 3, an adjustable ventilation mechanism, an upper housing 4, and a secondary purification mechanism. Compared with the prior art where the purification device uses a filtration and purification method to treat industrial waste gas, the purification method is relatively single, and the filter screen is prone to clogging after long-term use, resulting in poor purification effect on industrial waste gas. In this embodiment, through the rotatably arranged spraying member, preliminary spraying and purification of industrial waste gas are achieved, thereby realizing the spraying and precipitation of impurities carried in the industrial waste gas, reducing the amount of impurities carried in the industrial waste gas, and facilitating subsequent purification treatment of the industrial waste gas. Through the drying component inside the drying chamber 201, drying treatment of the water vapor carried in the industrial waste gas is achieved, reducing the water vapor carried in the industrial waste gas, and reducing the probability of the phenomenon that excessive water vapor affects the filtration and adsorption treatment effect of industrial waste gas, ensuring the purification treatment effect of industrial waste gas. Through the secondary purification mechanism, filtration and adsorption treatment of industrial waste gas are achieved, thereby realizing multi-stage purification of industrial waste gas, enhancing the treatment effect of industrial waste gas, and reducing the pollution caused by industrial waste gas discharged into the external environment. Through two groups of adjustable ventilation mechanisms, adjustment of the ventilation state inside the two lower housings 3 is achieved, enabling the staff to adjust the ventilation state inside the two lower housings 3 according to the usage requirements, thereby facilitating the staff to disassemble and clean the secondary purification mechanism after long-term use, and further ensuring the purification treatment effect of the secondary purification mechanism. Moreover, the design of the two groups of secondary purification mechanisms enables the purification device to ensure normal operation when cleaning one of the groups of secondary purification mechanisms, thus ensuring the normal operation of the device.

[0023] As Figure 1 and Figure 2As shown in the figure, an intake pipe 5 is connected to the lower side of one side of the two sides of the purification box 2. The spraying member is rotatably installed inside the purification box 2 through a rotating shaft 101. A driving member for driving the rotating shaft 101 to rotate is provided on the purification box 2. The spraying member includes a rotating shaft 101, a water storage tank 102, and a spraying nozzle 103. The middle part of the upper side of the water storage tank 102 is connected to an external pipeline, and the external pipeline is connected to an external water pump. The lower half of the external pipeline is an elastic telescopic pipe. A limiting ring is sleeved in the middle of the external pipeline, and the limiting ring is installed on the upper side of the purification box 2 through an L-shaped plate. The spraying member can spray and purify the industrial waste gas entering the inside of the purification box 2. And because the spraying mechanism can rotate, it can achieve comprehensive spraying of the industrial waste gas entering the inside of the purification box 2, so as to quickly spray and settle the impurities carried in the industrial waste gas. Two drain valves are connected to the lower side of the purification box 2. The staff can discharge the spraying water from the purification box 2 through the drain valves, which facilitates the staff to use the purification box 2 and the spraying mechanism to process the subsequent industrial waste gas; As Figure 1 shown, the drying bin 201 is installed on one side of the two sides of the purification box 2 through a connecting plate. A drying component is arranged inside the drying bin 201. As Figure 3 shown, the drying component includes a first drying layer 202 and a second drying layer 203. Support legs 6 are installed on the lower side of the drying bin 201. Silica gel, anhydrous calcium chloride, activated alumina, quicklime desiccant and other materials can be filled inside the first drying layer 202 and the second drying layer 203. The drying component inside the drying bin 201 can dry the water vapor carried in the industrial waste gas entering the inside of the drying bin 201, thereby reducing the amount of water vapor carried in the industrial waste gas and reducing the probability of the phenomenon that too much water vapor carried in the industrial waste gas affects the subsequent purification effect of the industrial waste gas; As Figure 1 shown, two lower shells 3 are installed on the drying bin 201 through L-shaped rods. The lower side of the lower shell 3 is connected to the upper side of the drying bin 201 through a second pipeline. As Figure 4 shown, an adjustable mechanism is arranged inside the lower shell 3. The upper shell 4 is movably buckled on the upper side of the lower shell 3. A sealing groove is opened on the upper side of the lower shell 3. A sealing ring is installed on the lower side of the upper shell 4. The cooperation of the sealing ring and the sealing groove realizes the sealing between the lower shell 3 and the upper shell 4, thereby ensuring the sealing effect after the upper shell 4 is buckled on the lower shell 3 and reducing the probability of air leakage. The adjustable ventilation mechanism includes a ventilation member and an adjusting member. As Figure 5As shown, the ventilation member includes a first mounting ring 301, a fixed ventilation disc 302, and a rotatable ventilation disc 303. A plurality of ventilation holes are provided on both the fixed ventilation disc 302 and the rotatable ventilation disc 303. When the ventilation member is in the ventilation state, the ventilation holes on the fixed ventilation disc 302 and the rotatable ventilation disc 303 are in a corresponding and communicating state. When the ventilation member is in the non-ventilation state, the ventilation holes on the fixed ventilation disc 302 and the rotatable ventilation disc 303 are in a staggered state, as Figure 6 As shown, the adjusting member includes an adjusting handle 401, a guide post 402, and a spring pin 403. A moving opening is provided on the lower housing 3. The width of the moving opening is adapted to the width of the adjusting handle 401. The staff can rotate the rotatable ventilation disc 303 through the adjusting handle 401. When the adjusting handle 401 moves, it moves inside the moving opening, thereby realizing the adjustment of the ventilation state of the ventilation member, and further realizing the adjustment of the ventilation state inside the lower housing 3. Positioning slots are provided on both the adjusting handle 401 and the guide post 402. The spring pin 403 can insert and position the adjusting handle 401 and the guide post 402 through the positioning slots, thereby realizing the positioning after the rotation of the rotatable ventilation disc 303 and ensuring the stability after the adjustment of the ventilation state of the ventilation member; As Figure 4 shown, the secondary purification mechanism is arranged inside the upper housing 4, as Figure 6 As shown, the secondary purification mechanism includes a second mounting ring 501, a filter layer 502, an adsorption layer 503, and bolts 504. The filter layer 502 is composed of a plurality of filter meshes. The filter meshes inside the filter layer 502 can filter and purify the industrial waste gas flowing through the filter layer 502. An activated carbon adsorbent is provided inside the adsorption layer 503. The activated carbon adsorbent inside the adsorption layer 503 can adsorb and purify the industrial waste gas flowing through the adsorption layer 503. The bolts 504 can realize the quick installation or disassembly of the secondary purification mechanism, thereby facilitating the staff to clean or replace the filter layer 502 and the adsorption layer 503 inside the secondary adsorption mechanism.

[0024] Working principle: The industrial waste gas to be treated enters the purification box 2 through the air inlet pipe 5. At this time, an external pipeline is connected to an external water pump. The external water pump transports the spraying water through the external pipeline to the inside of the water storage tank 102, and then flows from the water storage tank 102 into the spraying nozzle 103. The spraying nozzle 103 sprays the spraying water onto the industrial waste gas entering the purification box 2, thereby realizing the preliminary spraying and purification of the industrial waste gas. During the spraying process, the reciprocating motor is started. The reciprocating motor drives the rotating shaft 101 to rotate. The rotating shaft 101 drives the water storage tank 102 to rotate. The water storage tank 102 drives the spraying nozzle 103 to reciprocally deflect with the rotating shaft 101 as the center, so that the spraying water sprayed by the spraying nozzle 103 can comprehensively spray and purify the industrial waste gas entering the purification box 2; The industrial waste gas purified by spraying flows into the interior of the drying bin 201 through the first pipeline. When the industrial waste gas flows through the first drying layer 202, the desiccant inside the first drying layer 202 preliminarily dries the water vapor in the industrial waste gas. When the preliminarily dried industrial waste gas flows through the second drying layer 203, the desiccant inside the second drying layer 203 performs secondary drying on the water vapor in the industrial waste gas, thereby realizing the multi-stage drying treatment of the water vapor carried in the industrial waste gas; The industrial waste gas dried by the drying mechanism flows into the lower housing 3 through the second pipeline, and then flows from the lower housing 3 into the upper housing 4. When the industrial waste gas flows through the filter layer 502, multiple filter meshes inside the filter layer 502 filter and intercept the impurities carried in the industrial waste gas. When the filtered industrial waste gas flows through the adsorption layer 503, the activated carbon desiccant inside the adsorption layer 503 adsorbs the harmful substances in the industrial waste gas, thereby realizing the secondary treatment of the industrial waste gas. The treated industrial waste gas is discharged to the external environment through the exhaust port; When one of the two sets of secondary purification mechanisms is blocked after long-term use, the staff pulls the spring pin 403 to cancel the positioning between the adjusting handle 401 and the guide post 402 by the spring pin 403. After cancellation, the staff pushes the adjusting handle 401 to move along the guide post 402. While the adjusting handle 401 moves, it drives the rotary ventilation disc 303 to rotate. While the rotary ventilation disc 303 rotates, the states of the ventilation holes opened on the fixed ventilation disc 302 and the rotary ventilation disc 303 change from the corresponding same state to a staggered state. At this time, the ventilation member changes from the ventilation state to the non-ventilation state. After adjustment, the staff positions the adjusting handle 401 and the guide post 402 through the spring pin 403 to ensure the stability of the rotary ventilation disc 303 after rotation adjustment. After the ventilation state adjustment is completed, the staff removes the upper housing 4 with the blocked secondary purification mechanism from the lower housing 3. After removal, the staff counterclockwise rotates the bolt 504 to cancel the fixation between the bolt 504 and the second mounting ring 501 on the upper housing 4. Then, the second mounting ring 501 equipped with the filter layer 502 and the adsorption layer 503 is taken out from the interior of the upper housing 4. After removal, the staff cleans or replaces the filter layer 502 and the adsorption layer 503, thereby realizing the cleaning of the blocked secondary purification mechanism. After cleaning, the upper housing 4 and the secondary purification mechanism are reinstalled in place. While one of the two sets of secondary purification mechanisms is being cleaned, the industrial waste gas can be discharged to the external environment after being treated by the other set of secondary purification mechanisms, thereby ensuring the normal operation of the purification equipment.
