Description

Technical Field

[0001] The utility model relates to the field of waste gas absorption equipment, in particular to waste gas environmental pollution control absorption equipment. Background Art

[0002] Waste gas absorption equipment is used to purify and treat harmful gases generated in industrial production, transportation and other processes. The main function of waste gas absorption equipment is to remove pollutants in waste gas through physical and chemical methods, such as volatile organic compounds (VOCs), dust, odorous gases, etc., to reduce the impact on the environment and protect air quality. The use of efficient waste gas absorption equipment can effectively reduce waste gas emissions and achieve environmental protection goals.

[0003] Most of the existing waste gas absorption equipment sends the waste gas into the waste gas treatment structure by setting up a blower. The blower keeps transporting the waste gas, which will cause the waste gas flow rate to be too fast, resulting in incomplete contact with the liquid, thus affecting the purification effect. At the same time, most of the existing equipment uses spraying to make the gas contact with the liquid, and there is also the situation of incomplete liquid contact. In addition, most of the existing equipment does not have a structure for cleaning the filter plate and the demisting layer, which will cause the filter plate and the demisting layer to be contaminated and affect the waste gas purification effect.

[0004] Therefore, those skilled in the art provide a waste gas environmental pollution control absorption device to solve the problems raised in the above background technology. Utility Model Content

When the incomplete gear rotates, the gear teeth engage with the teeth inside the slip ring, causing the slip ring to slide inside the slide rail. At the same time, the piston is driven by the connecting rod to slide inside the gas collecting box. When the piston slides outwards, the exhaust gas enters the gas collecting box from the exhaust gas inlet pipe. When the piston slides inwards, the exhaust gas in the gas collecting box is input into the shunt pipe inside the box body through the air delivery pipe, realizing intermittent exhaust gas input, slowing down the exhaust gas flow rate and prolonging the exhaust gas treatment time.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Refer to Figure 1 , an embodiment provided by the present invention: An absorption device for treating exhaust gas environmental pollution includes a box body 1, an exhaust pipe 6 is fixedly arranged at the upper end of the box body 1, an exhaust gas treatment structure 7 is fixedly arranged inside the box body 1, an exhaust gas introduction structure 3 is fixedly arranged on one side of the box body 1, a water circulation structure 2 is fixedly arranged on the side of the box body 1 away from the exhaust gas introduction structure 3, six support legs 5 are fixedly arranged at the lower end of the box body 1, a bearing seat 4 is fixedly arranged at the lower ends of the six support legs 5, and the exhaust gas introduction structure 3 and the water circulation structure 2 are on the bearing seat 4;

[0027] Specifically, when the device is in use, the exhaust gas introduction structure 3 conveys the exhaust gas into the box body 1, and the exhaust gas is discharged from the exhaust pipe 6 after being purified by the exhaust gas treatment structure 7 inside the box body 1. During the working process, the water circulation structure 2 filters the water inside the device and reuses it, reducing the waste of water resources.

[0028] Refer to Figure 2, the water circulation structure 2 includes a water tank 201. A water pump 202 is fixedly arranged at the upper end of the water tank 201. A water suction pipe 206 is fixedly sleeved at the water inlet of the water pump 202. The other end of the water suction pipe 206 penetrates through the water tank 201 and leads to the inside of the water tank 201. A water delivery pipe 205 is fixedly sleeved at the water outlet of the water pump 202. A connecting pipe 209 is fixedly sleeved at the other end of the water delivery pipe 205. Three water inlet pipes 211 are fixedly sleeved on the side of the connecting pipe 209 close to the box body 1. The other ends of the three water inlet pipes 211 penetrate through the box body 1 and lead to the inside of the box body 1;

[0029] A filter screen 207 is fixedly arranged inside the water tank 201 below the pipe orifice of the water suction pipe 206. A circulation port 210 is opened at the bottom of the inner wall of the water tank 201 close to the box body 1. A sedimentation tank 208 is opened on the inner bottom surface of the water tank 201. A sewage discharge pipe 203 is fixedly sleeved at the lower part of the side of the water tank 201 far from the box body 1. A valve 204 is fixedly arranged on the pipe body of the sewage discharge pipe 203. The sewage discharge pipe 203 is communicated with the bottom of the sedimentation tank 208;

[0030] Specifically, during the working process, the water pump 202 in the water circulation structure 2 pumps the water in the water tank 201 through the water suction pipe 206, sends it to the connecting pipe 209 through the water delivery pipe 205, then diverts it from the connecting pipe 209 to the three water inlet pipes 211, and finally conveys it into the box body 1. Then the water in the box body 1 flows into the water tank 201 through the circulation port 210. The water in the water tank 201 is filtered by setting the filter screen 207. The filtered water is sucked away by the water pump 202 for reuse. The filtered impurities will sink to the bottom of the sedimentation tank 208. The impurities at the bottom of the sedimentation tank 208 can be discharged by setting the sewage discharge pipe 203, and the dredging of the sewage discharge pipe 203 is controlled by setting the valve 204.

[0031] Refer to Figure 2 , the waste gas treatment structure 7 includes a shunt pipe 702. A placement rack 701 is fixedly arranged at the lower end of the shunt pipe 702. The lower end of the placement rack 701 is fixedly arranged on the inner bottom surface of the box body 1. A plurality of uniformly distributed gas spray nozzles 703 are fixedly arranged at the upper end of the shunt pipe 702;

[0032] On the four inner walls of the box body 1 above the gas spray nozzles 703, a first flushing pipe 704, a filter plate 706, a second flushing pipe 707, a third flushing pipe 708, and a demisting layer 709 are fixedly arranged in sequence from bottom to top. A plurality of uniformly distributed liquid spray nozzles 705 are fixedly arranged on the side of the first flushing pipe 704 and the second flushing pipe 707 close to the filter plate 706. A plurality of uniformly distributed liquid spray nozzles 705 are fixedly arranged on the side of the third flushing pipe 708 close to the demisting layer 709. The ends of the first flushing pipe 704, the second flushing pipe 707, and the third flushing pipe 708 close to the connecting pipe 209 are communicated with the ends of the three corresponding water inlet pipes 211 penetrating through the box body 1;

[0033] Specifically, by setting up the placement rack 701, the influence of the lower position of the shunt pipe 702 on the water flowing from the box body 1 into the water tank 201 is avoided. By setting the shunt pipe 702 in the water, the waste gas is directly in contact with the water after being ejected from the gas nozzles 703 evenly distributed at the upper end of the shunt pipe 702. The full contact between the waste gas and the water can effectively remove dust and pollutants soluble in water. By setting the filter plate 706, pollutants insoluble in water in the gas can be filtered. By setting the demisting layer 709, the moisture in the gas can be intercepted, preventing the pollutants soluble in water contained in the moisture from being carried out and causing environmental pollution. By setting the first flushing pipe 704, the second flushing pipe 707, and the third flushing pipe 708 to be respectively connected to the corresponding water inlet pipe 211, the three flushing pipes can continuously flush the filter plate 706 and the demisting layer 709 during the working process to ensure their cleanliness, which is beneficial to maintaining a good waste gas purification effect.

[0034] Refer to Figure 5 , the demisting layer 709 includes a fixed frame 70901, and a row of corrugated plates 70902 are fixedly arranged inside the fixed frame 70901. A reflux plate 70903 is fixedly arranged at the protruding part near the lower end of the corrugated plate 70902;

[0035] Specifically, by setting the corrugated plates 70902, the contact area between the gas and the plates is increased, which can increase the probability of intercepting the moisture in the gas. By setting the reflux plate 70903, a reflux is formed at the reflux plate 70903 when the gas flows, which can effectively intercept the moisture in the gas and prevent the pollutants soluble in water contained in the moisture from being carried out and causing environmental pollution.

[0036] Refer to Figure 3-4 , the waste gas introduction structure 3 includes a motor 301. A fixed seat 303 is fixedly arranged at the lower end of the motor 301. The fixed seat 303 is fixed on the receiving seat 4. A slide rail 302 is fixedly arranged at the receiving seat 4 near the fixed seat 303. A sliding ring 308 is slidably sleeved in the chute of the slide rail 302. Engagement teeth 309 are fixedly arranged on the horizontal inner walls on both sides of the sliding ring 308. The output end of the motor 301 penetrates through the slide rail 302 and is fixedly sleeved with an incomplete gear 310. The incomplete gear 310 meshes with the engagement teeth 309;

[0037] A connecting rod 304 is fixedly arranged on one side of the sliding ring 308 close to the box body 1. A piston 311 is fixedly arranged on the side of the connecting rod 304 away from the sliding ring 308. A gas collecting box 305 is fixedly arranged at the upper end of the receiving seat 4 near the slide rail 302. The piston 311 is movably sleeved inside the gas collecting box 305. An exhaust gas inlet pipe 306 is fixedly arranged at the upper end of the gas collecting box 305 away from the slide rail 302. A one-way valve 312 is arranged inside the exhaust gas inlet pipe 306. An air delivery pipe 307 is fixedly arranged on one side of the gas collecting box 305 away from the slide rail 302. The other end of the air delivery pipe 307 penetrates through the box body 1 and is connected to the shunt pipe 702. A one-way valve 312 is arranged inside the air delivery pipe 307;

[0038] Specifically, during operation, the motor 301 in the exhaust gas introduction structure 3 drives the incomplete gear 310 to rotate. When the incomplete gear 310 rotates, the teeth engage with the engaging teeth 309 inside the slip ring 308, causing the slip ring 308 to slide inside the slide rail 302. When the teeth engage with the lower engaging teeth 309 and rotate, the slip ring 308 slides away from the box body 1. The slip ring 308 drives the piston 311 to slide outwards through the connecting rod 304. At this time, the exhaust gas enters the gas collecting box 305 from the exhaust gas inlet pipe 306. When the teeth engage with the upper engaging teeth 309 and rotate, the slip ring 308 slides towards the box body 1. The slip ring 308 drives the piston 311 to slide inwards through the connecting rod 304. At this time, the exhaust gas in the gas collecting box 305 is input into the shunt pipe 702 inside the box body 1 through the gas transmission pipe 307, realizing intermittent exhaust gas input, slowing down the exhaust gas flow rate and prolonging the exhaust gas treatment time. By setting the one-way valve 312, it is possible to prevent the gas in the exhaust gas inlet pipe 306 and the gas transmission pipe 307 from flowing back.

[0039] Working principle: When the equipment is in use, the motor 301 of the exhaust gas introduction structure 3 drives the incomplete gear 310 to rotate. When the incomplete gear 310 rotates, the teeth engage with the engaging teeth 309 inside the slip ring 308, causing the slip ring 308 to slide inside the slide rail 302. At the same time, the piston 311 is driven to slide inside the gas collecting box 305 through the connecting rod 304. When the piston 311 slides outwards, the exhaust gas enters the gas collecting box 305 from the exhaust gas inlet pipe 306. When the piston 311 slides inwards, the exhaust gas in the gas collecting box 305 is input into the shunt pipe 702 inside the box body 1 through the gas transmission pipe 307. Then, the exhaust gas is ejected from the gas ejector 703 at the upper end of the shunt pipe 702. The ejected gas contacts the water, which can remove the dust and water-soluble pollutants in the water. Then, the exhaust gas filters the pollutants insoluble in water inside through the filter plate 706. Finally, the filtered gas removes the moisture in the gas through the demisting layer 709 and is discharged from the exhaust pipe 6;

[0040] Secondly, during operation, the water pump 202 in the water circulation structure 2 pumps the water in the water tank 201 through the water suction pipe 206, sends it to the connecting pipe 209 through the water transmission pipe 205, and then diverts it from the connecting pipe 209 to the three water inlet pipes 211. The water entering the water inlet pipe 211 is ejected from the liquid ejector 705 on the first flushing pipe 704, the second flushing pipe 707, and the third flushing pipe 708 to flush the filter plate 706 and the demisting layer 709. The flushed water falls to the bottom of the box body 1 and then flows into the water tank 201 through the circulation port 210. By setting the filter net 207, the water in the water tank 201 is filtered. The filtered water is sucked away by the water pump 202 for reuse. The filtered impurities will sink to the bottom of the sedimentation tank 208. By setting the sewage discharge pipe 203, the impurities at the bottom of the sedimentation tank 208 can be discharged. By setting the valve 204, the sewage discharge pipe 203 can be controlled to be unblocked.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features.
