Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, specifically to a waste gas treatment device for an integrated spray and bake paint booth. Background Technology

[0002] Spray booths generate a large amount of paint mist particles and volatile organic gases during operation. If these waste gases are not treated in time, they will affect the indoor environment, spraying quality, equipment safety and the health of operators. Direct emission will lead to air pollution and will not meet the relevant national environmental protection standards. However, the existing exhaust gas treatment devices for integrated spray booths still have some problems during use: First, existing devices mostly use only a single treatment method of filtration and adsorption, which has limited effect on purifying complex pollutants in exhaust gas and makes it difficult to achieve the optimal exhaust gas treatment standard. Secondly, the purification adsorption layer inside the device is mostly fixedly installed. Since the adsorption layer will become saturated after a period of use, the fixed installation method is not conducive to timely replacement of the adsorption layer, thus reducing the ease of use of the waste gas treatment device. Utility Model Content

[0003] In order to solve the problems of unsatisfactory treatment effect and inconvenient replacement of adsorption layer in existing waste gas treatment devices, the purpose of this utility model is to provide a waste gas treatment device for an integrated spray and bake paint booth.

[0004] To solve the above technical problems, this utility model adopts the following technical solution: a waste gas treatment device for an integrated spray and bake paint booth, comprising a base, a treatment tank fixedly installed on the upper surface of the base, an air inlet pipe connected to one side of the treatment tank, an installation ring fixedly sleeved on the outer surface of the air inlet pipe, the installation ring being installed at the air outlet of the paint booth by bolts, a water bath treatment component being provided inside the treatment tank and on the upper surface of the base, an air supply pipe connected to the upper surface of the treatment tank, a purification treatment component connected to the end of the air supply pipe, the water bath treatment component comprising a water tank, the water tank being fixedly installed on the upper surface of the base, a water suction pipe connected to one side of the water tank, a water pump connected to the end of the water suction pipe, the water pump being fixedly installed on the upper surface of the base, a delivery pipe connected to the output end of the water pump, a conveying pipe connected to the end of the delivery pipe penetrating the treatment tank and connected to an annular pipe, a nozzle connected to an annular array on the lower surface of the annular pipe, a drain pipe connected to the lower surface of the treatment tank for use with the nozzle, and a valve on the outer surface of the drain pipe.

[0005] Preferably, the purification and treatment component includes a treatment box, which is fixedly installed on the upper surface of the base.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows: 1.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example: Figure 1-4 As shown, this utility model provides a waste gas treatment device for an integrated spray-baking paint booth, including a base 1. A treatment tank 6 is fixedly installed on the upper surface of the base 1, serving as the main site for waste gas water bath treatment and providing space for various operations of the subsequent water bath treatment components 2, achieving preliminary purification of the waste gas. An air inlet pipe 7 is connected to one side of the treatment tank 6 to transport the paint booth waste gas to the treatment tank 6, which is the channel for the waste gas to enter the treatment device, ensuring a smooth start to the waste gas treatment process. An installation ring 9 is fixedly sleeved on the outer surface of the air inlet pipe 7. The installation ring 9 is installed at the air outlet of the paint booth by bolts, ensuring the airtightness of the waste gas transport and preventing waste gas leakage. A filter screen 8 is movably installed on one side of the installation ring 9, and the filter screen 8 is movably snapped into the air outlet of the paint booth, which can perform preliminary filtration of the waste gas entering the air inlet pipe 7, removing large particulate impurities and reducing the burden on the subsequent treatment components.

[0015] The interior of the treatment tank 6 and the upper surface of the base 1 are provided with a water bath treatment component 2 to achieve better treatment of waste gas. The upper surface of the treatment tank 6 is connected to a gas transmission pipe 5, which transports the waste gas treated by the water bath from the treatment tank 6 to the purification treatment component 3. It is a channel for the waste gas to be transmitted between the two treatment components. The end of the gas transmission pipe 5 is connected to the purification treatment component 3 to facilitate the replacement of the adsorption layer.

[0016] The water bath treatment component 2 includes a water tank 26, which is fixedly installed on the upper surface of the base 1. The water tank 26 stores water for water bath treatment and provides a water source for the water pump 24 to pump water. It is a basic support component for water bath treatment. The upper surface of the water tank 26 is provided with a water inlet 27, which facilitates the replenishment of water into the water tank 26. A sealing plug 28 is movably engaged with the inner wall of the water inlet 27. The sealing plug 28 can ensure the airtightness of the water tank 26 and prevent water leakage or the entry of external impurities.

[0017] A water pump 24 is connected to one side of the water tank 26. The end of the water pump 25 is connected to the water pump 24. The water pump 24 is fixedly installed on the upper surface of the base 1 to realize water transportation between the water tank 26 and the water pump 24. It is the channel for the water pump 24 to pump water. The output end of the water pump 24 is connected to the delivery pipe 23 to transport the water output by the water pump 24 to the annular pipe 202. It is a key component for water transportation in the water bath treatment assembly 2.

[0018] The end of the conveying pipe 23 passes through the treatment tank 6 and is connected to an annular pipe 202. The inner wall of the treatment tank 6 is symmetrically and fixedly connected with connecting rods 29. One side of the opposite face of the connecting rod 29 is fixedly connected to the outer surface of the annular pipe 202. The connecting rod 29 provides fixed support for the annular pipe 202, ensuring that the position of the annular pipe 202 is stable in the treatment tank 6, so that the nozzles 201 can spray water normally. The lower surface of the annular pipe 202 is connected to the nozzles 201 in an annular array. The annular pipe 202 is fixed in the treatment tank 6 by the connecting rod 29. The nozzles 201 are distributed in an annular array on the lower surface of the annular pipe 202, which can evenly spray water into the waste gas in the treatment tank 6, so that the waste gas and water can fully contact each other, thereby purifying the paint mist particles and some water-soluble organic waste gas in the waste gas.

[0019] The lower surface of the treatment tank 6 is connected to a drain pipe 22 for use with the nozzle 201. The drain pipe 22 is used to drain the water used in the treatment tank 6. The outer surface of the drain pipe 22 is provided with a valve 21, which can control the timing and flow of drainage, so as to facilitate the replacement or treatment of the water in the water tank 26.

[0020] The purification treatment component 3 includes a treatment box 37, which is fixedly installed on the upper surface of the base 1. It provides installation and working space for the activated carbon adsorption layer 33, the activated carbon fiber adsorption layer 32 and the zeolite adsorption layer 31, so as to achieve deep purification of the waste gas. An exhaust pipe 4 is connected to one side of the treatment box 37. The exhaust pipe 4 discharges the qualified waste gas after being treated by the purification treatment component 3 into the atmosphere, thus completing the entire waste gas treatment process.

[0021] The end of the gas supply pipe 5 is connected to the lower part of one side of the treatment box 37, so that the gas after water bath treatment can enter the treatment box 37 for purification treatment. The inner wall of the treatment box 37 is symmetrically fixed with clamping sleeves 36, which play a movable clamping role for the activated carbon adsorption layer 33, activated carbon fiber adsorption layer 32 and zeolite adsorption layer 31, respectively, so as to facilitate the installation and replacement of each adsorption layer.

[0022] The inner wall of the sleeve 36 is movably fitted with an activated carbon adsorption layer 33, an activated carbon fiber adsorption layer 32, and a zeolite adsorption layer 31. The activated carbon adsorption layer 33 utilizes its porous structure and large specific surface area to adsorb organic matter in the waste gas, such as benzene compounds, thereby purifying the organic components of the waste gas. The activated carbon fiber adsorption layer 32 has a higher specific surface area and a shorter adsorption diffusion path than activated carbon, resulting in faster adsorption speed and larger adsorption capacity. It has a better treatment effect on low-concentration, high-flow-rate organic waste gas. The zeolite adsorption layer 31 has a strong adsorption capacity for water and polar molecules, and can treat waste gas containing a small amount of moisture and polar organic matter. It also has good thermal and chemical stability.

[0023] A sealing cover 35 is movably snapped onto the upper surface of the treatment box 37. The sealing cover 35 is a rubber sheet. The lower surface of the sealing cover 35 is in close contact with the upper surfaces of the activated carbon adsorption layer 33, the activated carbon fiber adsorption layer 32, and the zeolite adsorption layer 31. The sealing cover 35 is a rubber sheet, and its lower surface is in close contact with the upper surface of each adsorption layer to ensure the airtightness of the treatment box 37 and prevent waste gas leakage. The sealing cover 35 is connected to a locking screw 34 through a common thread on the upper surface of the treatment box 37. The locking screw 34 fixes the sealing cover 35 to the upper surface of the treatment box 37, further enhancing the airtightness, and at the same time facilitating disassembly for replacement of the adsorption layers.

[0024] Working principle: First, the exhaust gas generated in the paint booth is discharged through the outlet, passing through the filter screen 8, which is attached to the outlet. The filter screen 8 performs preliminary filtration of larger particulate impurities in the exhaust gas, reducing the burden on subsequent treatment components. The filtered exhaust gas then enters the treatment tank 6 through the inlet pipe 7, which is fixed to the outlet of the paint booth by the mounting ring 9 and bolts to ensure the stability of the exhaust gas delivery.

[0025] After the exhaust gas enters the treatment tank 6, it is first treated by the water bath treatment component 2. The water tank 26 contains water for treating the exhaust gas. The water pump 24 is started, and the water pump 24 draws water from the water tank 26 through the water pumping pipe 25. Then, the water is transported to the annular pipe 202 through the delivery pipe 23. The annular pipe 202 is fixed to the inner wall of the treatment tank 6 by the connecting rod 29 to ensure structural stability.

[0026] The nozzles 201 on the lower surface of the annular pipe 202 are arranged in a ring array to spray water evenly into a water mist, which fully contacts the exhaust gas entering the treatment tank 6, and uses water to adsorb and settle soluble harmful substances and some particulate matter in the exhaust gas.

[0027] Wastewater treated by water bath is discharged through drain pipe 22 on the lower surface of treatment tank 6. The drainage speed and discharge volume can be controlled by valve 21. At the same time, water tank 26 can be replenished with water through water inlet 27. Sealing plug 28 is used to ensure the airtightness of water tank 26.

[0028] After being treated by the water bath, the exhaust gas moves upward and enters the purification treatment component 3 through the gas transmission pipe 5 on the upper surface of the treatment tank 6. Then, it enters the interior of the treatment box 37 from the lower side and passes through the activated carbon adsorption layer 33, the activated carbon fiber adsorption layer 32 and the zeolite adsorption layer 31, which are fixed by the sleeve 36 in sequence.

[0029] The activated carbon adsorption layer 33 is responsible for the deep adsorption of residual organic pollutants in the exhaust gas, while the activated carbon fiber adsorption layer 32 further and precisely adsorbs small molecule harmful substances, thus deepening the purification level. The zeolite adsorption layer 31 specifically adsorbs polar molecules in the exhaust gas. Through the synergistic effect of the above multi-layer adsorption, the exhaust gas is ultimately purified efficiently.

[0030] The sealing cover 35 on the upper surface of the treatment box 37 is a rubber plate, which is fixed by locking screws 34. Its lower surface is in close contact with each adsorption layer to ensure that the exhaust gas can only be treated through the adsorption layer and avoid short circuit. When the adsorption layer is saturated, the locking screws 34 can be unscrewed, the sealing cover 35 can be removed, and each adsorption layer can be replaced or regenerated.

[0031] Finally, the qualified exhaust gas, after undergoing multi-layer purification treatment, is discharged through the exhaust pipe 4 on one side of the treatment box 37, completing the entire exhaust gas treatment process.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
