Description

Technical Field

[0001] This utility model relates to the field of chemical waste gas treatment technology, and in particular to a waste gas purification tower for safe chemical production. Background Technology

[0002] Chemical engineering utilizes chemical reaction processes to produce various chemicals, materials, and energy. It involves transforming raw materials into more valuable products through chemical or biological conversion processes and has wide applications in all aspects of modern society. Chemical waste gas refers to gaseous pollutants released into the air during chemical production processes, including chemical reactions, raw material pretreatment, product refining, and byproduct generation. Therefore, waste gas purification towers are needed to purify and treat chemical waste gas.

[0003] The existing Chinese patent with publication number CN217855264U discloses a chemical waste gas purification tower for chemical safety production. The existing technical solution described above has the following defects: Although the above technical solution can filter and circulate the sprayed water through circulation pipes, water pumps, filter barrels, cashmere cotton, liquid inlet pipes, liquid outlet pipes, connecting pipes, and nozzles, reducing water waste, and the swirling mechanism composed of rings, discs, and inclined plates can make the sprayed water swirl, increasing the probability of contact with particles in the waste gas and thus increasing the purification effect of the waste gas, the flow of the waste gas in the tower body is poor. Therefore, the sprayed water cannot fully contact the waste gas in the tower body, resulting in some waste gas being discharged directly without being purified, which reduces the purification effect of the waste gas.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a waste gas purification tower for safe chemical production, which has the following beneficial effects:

[0016] (1) In this utility model, chemical waste gas is introduced into the tower body through the air inlet pipe. The impurities in the waste gas can be filtered by the first filter screen. At the same time as the waste gas is filtered, the pump body on the top surface of the mounting plate is turned on. The pump body transports water from the storage tank to the spray pipe through the water supply pipe. The water mist is then sprayed out through the nozzle on the spray pipe to purify the waste gas. The motor on the connecting plate is turned on. The motor drives the rotating rod to rotate, which causes the first helical gear on the rotating rod to rotate. At the same time, the first helical gear drives the second helical gear at one end of the connecting rod to rotate, which causes the stirring blade on the connecting rod to rotate. This stirs the waste gas in the tower body, increases the flow of the waste gas in the tower body, and allows it to fully contact the spray water, thereby improving the purification effect of the waste gas.

[0017] (2) In this utility model, the spray water after use is filtered through the second filter screen in the tower body, and the filtered water enters the storage tank again through the connecting pipe. By using the pump body on the top surface of the mounting plate, the water in the storage tank can be recycled, so that the water after use can be recycled, preventing the water after use from being directly discharged and causing waste of resources, which is conducive to improving its practicality.

[0026] Please refer to Figure 1-3A waste gas purification tower for chemical safety production includes a tower body 1. A first filter screen 15 is installed inside the tower body 1. A bearing seat is located on one side of the inner wall of the tower body 1 above the first filter screen 15, and a connecting rod 12 is installed in the bearing seat. One end of the connecting rod 12 passes through one side surface of the tower body 1 and is fixedly connected to a second helical gear 5. A connecting plate 3 is provided on one side surface of the tower body 1, and a motor 2 is fixedly installed on the top surface of the connecting plate 3. A rotating rod 6 is fixedly connected to the output end of the motor 2, and a first helical gear 4 is fixedly installed on the rotating rod 6. The first helical gear 4 meshes with the second helical gear 5. An agitator 11 is fixedly connected to the connecting rod 12 inside the tower body 1. A liquid storage tank 10 is provided below the tower body 1. A mounting plate 18 is provided on one side surface of the tower body 1, and a pump body 17 is fixedly installed on the top surface of the mounting plate 18.

Next, an air inlet pipe 7 is provided on one side surface of the tower body 1 below the connecting plate 3, and an exhaust pipe 13 is provided at the middle position of the top surface of the tower body 1. Chemical waste gas is introduced into the tower body 1 through the air inlet pipe 7. Impurities in the waste gas can be filtered by the first filter screen 15. At the same time as the waste gas is filtered, the pump body 17 on the top surface of the mounting plate 18 is turned on. The pump body 17 pumps water from the storage tank 10 through the water pipe to the spray pipe 16, and then sprays it out through the nozzles 14 on the spray pipe 16. Water mist can purify the exhaust gas. When the motor 2 on the connecting plate 3 is turned on, the motor 2 drives the rotating rod 6 to rotate, which in turn drives the first helical gear 4 on the rotating rod 6 to rotate. At the same time, the first helical gear 4 drives the second helical gear 5 at one end of the connecting rod 12 to rotate, which in turn drives the agitator 11 on the connecting rod 12 to rotate. This agitates the exhaust gas in the tower body 1, increases the flow of the exhaust gas in the tower body 1, and allows it to fully contact the sprayed water, thereby improving the purification effect of the exhaust gas.

[0027] In one embodiment, a second filter screen 22 is provided inside the tower body 1 below the first filter screen 15, wherein the used spray water is filtered through the second filter screen 22 in the tower body 1 to filter out impurities in the water.

[0028] In one embodiment, a connecting pipe 8 is provided at the middle position of the bottom surface of the tower body 1, and one end of the connecting pipe 8 extends into the interior of the liquid storage tank 10. The filtered water re-enters the liquid storage tank 10 through the connecting pipe 8. The water in the liquid storage tank 10 can be recycled by using the pump body 17 on the top surface of the mounting plate 18.

[0029] In one embodiment, a plurality of first filter screens 15 are provided, and the plurality of first filter screens 15 are evenly distributed inside the tower body 1. The use of the plurality of first filter screens 15 can improve the filtration effect of exhaust gas.

[0032] In one embodiment, a movable plate 20 is provided at the middle position of the front surface of the tower body 1, and the movable plate 20 is fixedly connected to the tower body 1 by screws. By loosening the screws and removing the movable plate 20, the components in the tower body 1 can be maintained and repaired.

[0033] In one embodiment, the control switch control circuit can be implemented by simple programming by those skilled in the art, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0034] Working principle:

[0035] In operation, chemical waste gas is introduced into the tower body 1 through the inlet pipe 7. The first filter screen 15 filters impurities from the waste gas. Simultaneously, the pump body 17 on the top surface of the mounting plate 18 is activated. The pump body 17 pumps water from the storage tank 10 through a water pipe to the spray pipe 16, where it sprays water mist from the nozzles 14, purifying the waste gas. The motor 2 on the connecting plate 3 is activated, causing the rotating rod 6 to rotate. This causes the first helical gear 4 on the rotating rod 6 to rotate, which in turn drives the second helical gear 5 at one end of the connecting rod 12 to rotate. The agitator blade 11 on the connecting rod 12 rotates, which agitates the waste gas in the tower body 1, increases the flow of the waste gas in the tower body 1, and allows it to fully contact the spray water, thereby improving the purification effect of the waste gas. The spray water after use is filtered through the second filter screen 22 in the tower body 1, and the filtered water re-enters the storage tank 10 through the connecting pipe 8. The water in the storage tank 10 can be recycled by the pump body 17 on the top surface of the mounting plate 18, thus preventing the waste of resources caused by direct discharge of the used water and improving its practicality.
