Description

Technical Field

[0001] This utility model relates to the field of industrial waste gas treatment technology, and specifically discloses a purification device for industrial waste gas treatment. Background Technology

[0002] Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory area. Smoke and dust particles make the air very turbid, block sunlight, and reduce the amount of solar radiation reaching the ground. Smoke and industrial dust emitted into the atmosphere pollute the air. These substances enter the human body through the respiratory tract through different pathways. Some cause direct harm, while others have an accumulation effect, which can more seriously endanger human health. Therefore, it is necessary to purify and treat the smoke and dust particles in industrial waste gas.

[0003] Existing industrial waste gas treatment devices mostly treat industrial waste gas through activated carbon filters. However, industrial waste gas contains a large amount of particulate matter, which easily adheres to the activated carbon filter during purification, clogging it and affecting its filtration efficiency. Regular cleaning of the activated carbon filter is required, which is inconvenient. Furthermore, existing industrial waste gas treatment devices are not easy to disassemble and install the activated carbon filter, as the process is cumbersome and time-consuming, severely impacting the efficiency of industrial waste gas purification. Utility Model Content

[0004] This invention proposes a purification device for industrial waste gas treatment, which can separate dust particles from industrial waste gas, preventing them from adsorbing onto the activated carbon filter and clogging it, thus effectively improving the filtration effect. At the same time, it can increase the service life of the activated carbon filter, reduce the frequency of cleaning, maintenance and replacement, and facilitate the disassembly and installation of the activated carbon filter, avoiding any impact on the purification efficiency of industrial waste gas.

[0005] This utility model is implemented as follows: a purification device for industrial waste gas treatment includes a base, and the upper surface of the base is provided with a primary purification mechanism, a water-gas separator and a secondary purification mechanism from left to right.

[0006] The primary purification mechanism includes a spray box fixedly connected to the upper surface of the base. The spray box is equipped with a cross-shaped spray pipe inside, and the lower end of the spray pipe is connected to multiple evenly distributed atomizing nozzles.

[0007] The secondary purification mechanism includes a filter box fixedly connected to the upper surface of the base. The upper surface of the filter box has a through notch. The upper surface of the filter box is fixedly connected to a mounting plate that matches the notch by bolts. The lower surface of the mounting plate is detachably connected to an activated carbon filter screen that passes through the notch and matches the inner wall of the filter box.

[0008] As a preferred embodiment of the purification device for industrial waste gas treatment according to this utility model, a first conveying pipe is connected between the upper end face of the spray box and the water-gas separator, and a second conveying pipe is connected between the left side wall of the filter box and the water-gas separator.

[0009] As a preferred embodiment of the purification device for industrial waste gas treatment according to this utility model, an air inlet pipe is fixedly connected to the left side wall of the spray box, and one end of the air inlet pipe extends to the lower end of the interior of the spray box.

[0010] As a preferred embodiment of the purification device for industrial waste gas treatment according to this utility model, a liquid inlet pipe is fixedly connected to the left side wall of the spray box, and one end of the liquid inlet pipe extends into the interior of the spray box and communicates with the spray pipe.

[0011] As a preferred embodiment of the purification device for industrial waste gas treatment according to this utility model, the lower end of the left side wall of the spray box is connected to a drain pipe, and an electromagnetic valve is installed inside the drain pipe.

[0012] As a preferred embodiment of the purification device for industrial waste gas treatment according to this utility model, the outer wall of the water-gas separator is fixedly connected to a support plate, and a plurality of evenly distributed support legs are fixedly connected between the support plate and the base.

[0013] As a preferred embodiment of the purification device for industrial waste gas treatment according to this utility model, a plurality of evenly distributed fixing rods are fixedly connected between the spray pipe and the upper part of the spray box.

[0014] The beneficial effects of this utility model are:

[0015] The exhaust gas is initially removed by water at the bottom of the spray box. Then, the exhaust gas rises and comes into contact with the water mist again, which further removes the dust particles. This separates the dust particles from the exhaust gas, preventing them from adsorbing onto the activated carbon filter and clogging it. This effectively improves the filtration effect, increases the service life of the activated carbon filter, and reduces the frequency of cleaning, maintenance, and replacement.

[0016] When replacing the activated carbon filter, unscrew the bolts securing the mounting plate, then pull the mounting plate upwards. The mounting plate will then pull the activated carbon filter out of the filter box through the notch. Clean, maintain, or replace the activated carbon filter. After completion, reverse the above steps to install the activated carbon filter. This facilitates the disassembly and installation of the activated carbon filter, preventing any impact on the purification efficiency of industrial waste gas. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-4 An industrial waste gas treatment purification device includes a base 1, and a primary purification mechanism, a water-gas separator 2 and a secondary purification mechanism are arranged sequentially from left to right on the upper surface of the base 1.

[0025] The primary purification mechanism includes a spray box 3 fixedly connected to the upper surface of the base 1. The spray box 3 is equipped with a cross-shaped spray pipe 4, and the lower end of the spray pipe 4 is connected to multiple evenly distributed atomizing nozzles 5.

[0026] The secondary purification mechanism includes a filter box 6 fixedly connected to the upper surface of the base 1. A notch 7 is provided through the upper surface of the filter box 6. An installation plate 8 matching the notch 7 is fixedly connected to the upper surface of the filter box 6 by bolts. An activated carbon filter screen 9 that passes through the notch 7 and matches the inner wall of the filter box 6 is detachably connected to the lower surface of the installation plate 8.

[0027] In this embodiment: When in use, first connect the external water pipe to the liquid inlet pipe 13, connect the two external exhaust gas delivery pipes to the air inlet pipe 12 and the exhaust pipe on the right side wall of the filter box 6 respectively, and then deliver an appropriate amount of water into the spray box 3 through the water injection pipe on the upper end of the spray box 3 so that the water level is located in the middle of the air inlet pipe 12 of the spray box 3, thereby completing the preparation of the device.

[0028] Water is then supplied to the spray pipe 4 through an external water pipe and liquid inlet pipe 13. The water is then atomized and sprayed out through multiple atomizing nozzles 5. Simultaneously, exhaust gas is supplied to the spray box 3 through an external exhaust gas supply pipe and air inlet pipe 12. Because the water level is located in the middle of the air inlet pipe 12 of the spray box 3, the exhaust gas first contacts the water at the lower end of the spray box 3. The water at the lower end of the spray box 3 initially removes particulate matter from the exhaust gas. Then, the exhaust gas rises, allowing it to contact the water mist again, further removing particulate matter from the exhaust gas. The process of separating particulate matter from the exhaust gas prevents it from adsorbing onto the activated carbon filter 9 and clogging it, thus effectively improving the filtration effect. At the same time, it increases the service life of the activated carbon filter 9 and reduces the frequency of cleaning, maintenance and replacement. At this time, the solenoid valve 15 is in the open state, allowing the water at the bottom of the spray box 3 to be slowly discharged through the drain pipe 14. The drainage speed of the drain pipe 14 is the same as the spraying speed of the spray pipe 4, so that the water at the bottom of the spray box 3 is always kept at a suitable level.

[0029] Then, the exhaust gas after the first treatment is transported to the water-gas separator 2 through the first conveying pipe 10. Since the exhaust gas after the first spray treatment contains water vapor, the water-gas separator 2 can separate the exhaust gas from the water vapor, making the exhaust gas dry and preventing the activated carbon filter screen 9 from getting damp and affecting the filtration effect of the activated carbon filter screen 9. Then, the dried exhaust gas enters the filter box 6 through the second conveying pipe 11 and is filtered by the activated carbon filter screen. Then, the exhaust gas after the second treatment is discharged through the exhaust pipe and exhaust gas conveying pipe on the right side wall of the filter box 6, thus effectively purifying the exhaust gas through multi-stage treatment.

[0030] When replacing the activated carbon filter 9, unscrew the bolts fixing the mounting plate 8, and then pull the mounting plate 8 upward. The mounting plate 8 will drive the activated carbon filter 9 out of the filter box 6 through the notch 7. Then clean, maintain or replace the activated carbon filter 9. After completion, reverse the above steps to install the activated carbon filter 9, which facilitates the disassembly and installation of the activated carbon filter 9 and avoids affecting the purification efficiency of industrial waste gas.

[0031] As a technical optimization of this utility model, a first conveying pipe 10 is connected between the upper end face of the spray box 3 and the water-air separator 2, and a second conveying pipe 11 is connected between the left side wall of the filter box 6 and the water-air separator 2.

[0032] In this embodiment, the first conveying pipe 10 and the second conveying pipe 11 can respectively convey the waste gas after primary treatment and drying.

[0033] As a technical optimization of this utility model, an air inlet pipe 12 is fixedly connected to the left side wall of the spray box 3, and one end of the air inlet pipe 12 extends to the lower end of the interior of the spray box 3.

[0034] In this embodiment, the air intake pipe 12 facilitates the delivery of waste gas into the spray box 3.

[0035] As a technical optimization of this utility model, a liquid inlet pipe 13 is fixedly connected to the left side wall of the spray box 3. One end of the liquid inlet pipe 13 extends into the interior of the spray box 3 and is connected to the spray pipe 4.

[0036] In this embodiment, water is conveniently delivered into the spray pipe 4 through the liquid inlet pipe 13.

[0037] As a technical optimization of this utility model, the lower end of the left side wall of the spray box 3 is connected to a drain pipe 14, and an electromagnetic valve 15 is installed inside the drain pipe 14.

[0038] In this embodiment: the water in the spray box 3 can be discharged through the drain pipe 14, and the drain pipe 14 can be blocked through the solenoid valve 15.

[0039] As a technical optimization of this utility model, a support plate 16 is fixedly connected to the outer wall of the water-air separator 2, and a plurality of evenly distributed support legs 17 are fixedly connected between the support plate 16 and the base 1.

[0040] In this embodiment, the water-air separator 2 is stably supported by the support plate 16 and multiple other components.

[0041] As a technical optimization of this utility model, a plurality of evenly distributed fixing rods 18 are fixedly connected between the spray pipe 4 and the upper part of the spray box 3.

[0042] In this embodiment, the spray pipe 4 can be supported and fixed by multiple fixing rods 18.

[0043] The working principle and usage process of this utility model are as follows: When in use, first connect the external water pipe to the liquid inlet pipe 13, connect the two external exhaust gas conveying pipes to the air inlet pipe 12 and the exhaust pipe on the right side wall of the filter box 6 respectively, and then deliver an appropriate amount of water into the spray box 3 through the water injection pipe on the upper end of the spray box 3 so that the water level is located in the middle of the air inlet pipe 12 of the spray box 3, thereby completing the preparation work of the device.

[0044] Then, water is supplied to the spray pipe 4 through the external water pipe and liquid inlet pipe 13. The water is then atomized and sprayed out through multiple atomizing nozzles 5. At the same time, exhaust gas is supplied to the spray box 3 through the external exhaust gas supply pipe and air inlet pipe 12. Since the water level is located in the middle of the air inlet pipe 12 of the spray box 3, the exhaust gas first comes into contact with the water at the bottom of the spray box 3. The water at the bottom of the spray box 3 initially removes the dust particles in the exhaust gas. Then, the exhaust gas floats upward, allowing the exhaust gas to come into contact with the water mist again. The water mist further removes the dust particles in the exhaust gas, thus separating the dust particles in the exhaust gas.

[0045] The exhaust gas after primary treatment is then transported to the water-gas separator 2 through the first conveying pipe 10. The water-gas separator 2 separates the exhaust gas from the water vapor, drying the exhaust gas. The dried exhaust gas then enters the filter box 6 through the second conveying pipe 11 and is filtered through the activated carbon filter. The exhaust gas after secondary treatment is then discharged through the exhaust pipe and exhaust gas conveying pipe on the right side wall of the filter box 6. Thus, the exhaust gas is effectively purified through multi-stage treatment.
