Description

Technical Field

[0001] This utility model relates to the field of environmental protection, specifically a spraying exhaust gas collection device. Background Technology

[0002] Roll rings are key components installed on rolling mill rolls, mainly used to control the shape and size of rolled products during the metal rolling process. They are mostly made of wear-resistant alloys or ceramics. Through cooperation with the rolls, they enable processing operations such as extrusion and stretching of metal materials. In the rolling fields of steel and non-ferrous metals, the performance of roll rings directly affects product quality and production efficiency.

[0003] During the processing of the roll ring, the size, curvature and surface texture of the roll ring are designed according to the rolling requirements. The metal structure of the roll ring is made denser through forging to improve its strength. Quenching and tempering are performed to improve the hardness and wear resistance of the roll ring. A grinding machine is used to perform high-precision grinding on the working surface of the roll ring to ensure roughness and dimensional tolerance. Finally, surface treatments such as chrome plating and ceramic coating are performed.

[0004] After spraying, a large amount of coating drying exhaust gas is emitted, which contains a high concentration of toluene. If this exhaust gas is discharged directly into the atmosphere without treatment, it will cause pollution to the surrounding environment. Therefore, a spraying exhaust gas collection device is proposed to address the above problem. Utility Model Content

As the sprayed exhaust gas passes below the water mist nozzle 15, the liquid in the water tank 12 enters the outlet 14 through the connecting pipe 13 and is sprayed out from the water mist nozzle 15 as a water mist. When the sprayed exhaust gas passes through the activated carbon plate 16, the activated carbon plate 16 adsorbs gases such as toluene in the sprayed exhaust gas. After the sprayed exhaust gas is treated, it is discharged from the air outlet of the fan 17. By first spraying water mist onto the sprayed exhaust gas, the solid particles, liquid paint mist and other impurities it carries settle down, reducing the concentration of particulate matter, reducing the clogging of the activated carbon plate 16, and increasing the service life of the activated carbon plate 16. The activated carbon plate 16 adsorbs volatile organic compounds such as toluene and xylene and odor substances in the exhaust gas, further removing harmful gases and reducing environmental pollution.

[0025] like Figures 1 to 3As shown, the bottom of the treatment tank 1 has a recovery port 2; a partition plate 21 is fixedly connected to the middle of the treatment tank 1; a filter plate 22 is fixedly connected to the top of the water tank 12; the filter plate 22 is fixedly connected to the top of the partition plate 21 at its end; the filter plate 22 is inclined; a collection box 23 is slidably connected to one side of the partition plate 21; a first sliding plate 24 is fixedly connected to the top of the water tank 12; the first sliding plate 24 is inclined; the first sliding plate 24 and the filter plate 22 are staggered; during operation, the water mist sprayed from the water mist nozzle 15 adheres to the paint particles or dust in the spraying exhaust gas, forming water droplets that fall into the recovery port 2 and settle in the water. The water droplets slide down the surface of the first slide plate 24 and onto the filter plate 22 for separation. The water droplets return to the inside of the water tank 12. Paint particles or dust slide down the surface of the filter plate 22 and onto the middle of the collection box 23. After the collection box 23 is full, it is pulled out for cleaning. By separating the water mist through the filter plate 22 and reusing it, liquid recycling can be achieved, reducing water waste. Paint particles or dust are intercepted on the surface of the filter plate 22 and slide down its slope into the collection box 23, reducing their secondary discharge with the water flow. The separated paint particles are collected, processed, and reused, reducing raw material loss.

[0026] like Figure 1 and Figure 4 As shown, a flow guide shroud 3 is fixedly connected to one side of the processing box 1; the flow guide shroud 3 is correspondingly arranged with the air inlet 11; a support 31 is fixedly connected to the middle of the flow guide shroud 3; a central flow guide cone 32 is fixedly connected to one side of the support 31; the central flow guide cone 32 is arranged on the side close to the flow guide shroud 3; during operation, the flow guide shroud 3 reduces the diffusion of the spray exhaust gas, causing it to flow along the inner wall of the flow guide shroud 3; the central flow guide cone 32 divides the spray exhaust gas through the cone surface, reducing the formation of a low-pressure vortex in the central area of ​​the flow guide shroud 3, and at the same time guides the airflow evenly to the surroundings. By installing the flow guide shroud 3 and the central flow guide cone 32 on the side of the air inlet 11, the suction of the fan 17 can be increased, reducing the diffusion of the spray exhaust gas to the surroundings and increasing its recovery effect. The central flow guide cone 32 uses the cone surface to guide the airflow evenly to the surroundings, reducing the low-pressure vortex in the central area, so that the paint exhaust gas passes evenly through the water mist nozzle 15, making the water mist and the particulate matter in the paint exhaust gas mix more fully, and improving the particulate matter capture efficiency.

[0027] like Figure 4As shown, an electrostatic mesh 4 is installed in the middle of the treatment box 1; it is located on the side near the flow guide hood 3; a connecting line 41 is fixed to the top of the treatment box 1; the connecting line 41 and the electrostatic mesh 4 are connected; a power supply is installed at the end of the connecting line 41; when working, the power is turned on, so that the current is transmitted to the surface of the electrostatic mesh 4 through the connecting line 41, so that the surface of the electrostatic mesh 4 is filled with an electrostatic field, adsorbing larger particles in the spray exhaust gas, reducing the blockage of filter plate 22 or activated carbon plate 16 by larger particles. After the power supply is turned off, the particles adsorbed by the electrostatic mesh 4 slide down the inner wall of the flow guide hood 3. By installing the electrostatic mesh 4 in the treatment box 1, large particles of paint can be intercepted, reducing their accumulation in the pores of the filter plate 22 and causing blockage, increasing the separation efficiency of water droplets and particles. At the same time, after the power supply is turned off, the electrostatic mesh 4 loses its electrostatic adsorption force, and the adsorbed particles slide down the inner wall of the flow guide hood 3 due to gravity, reducing the cleaning frequency.

[0028] like Figure 5 As shown, multiple supports 5 are fixedly connected to the middle of the treatment box 1; a heating rod 51 is installed between a group of supports 5; the heating rod 51 is arranged on one side of the activated carbon plate 16; a feed inlet 52 is opened at the bottom of the treatment box 1; a second sliding plate 53 is installed in the middle of the feed inlet 52; the second sliding plate 53 is inclined; a discharge outlet 54 is opened on one side of the water tank 12; the discharge outlet 54 is arranged above the collection box 23; the end of the second sliding plate 53 is fixedly connected to the discharge outlet 54; during operation, after the activated carbon plate 16 reaches adsorption saturation, the heating rod 51 is turned on to heat the activated carbon plate 16. The process removes moisture from the adsorbent material, reducing its volume and causing it to detach from the pores of the activated carbon plate 16. The detached adsorbent material falls into the feed inlet 52, slides down the second slide plate 53, and exits from the discharge outlet 54 into the collection box 23. The activated carbon plate 16 is heated by the heating rod 51, causing the adsorbed material to detach and restoring the pore adsorption capacity of the activated carbon, enabling reuse, increasing the service life of the activated carbon plate 16, and reducing the cost of consumable replacement. The detached adsorbent material falls into the bottom feed inlet 52 and into the collection box 23. During cleaning, the collection box 23 is removed for unified processing, reducing maintenance steps and increasing the convenience of operation.

[0029] like Figure 4 As shown, a silicone pad 6 is fixedly attached to the middle of the processing box 1; the silicone pad 6 wraps around the electrostatic mesh 4; the silicone pad 6 is made of antistatic material; during operation, the silicone pad 6 fills the gap between the electrostatic mesh 4 and the processing box 1, and at the same time uses its own material to intercept the static electricity on the surface of the electrostatic mesh 4 from being conducted to related components. By wrapping a silicone pad 6 around the electrostatic mesh 4, the current conduction to the processing box 1 or other components can be reduced, which could lead to short circuits, increasing the service life of electrical components such as the heating rod 51. At the same time, the silicone pad 6 can reduce the edge effect of the electrostatic mesh 4, increase the uniformity of the electric field, and increase the adsorption efficiency of the electrostatic mesh 4.

[0030] Working principle: By placing the treatment box 1 at the air outlet of the drying oven and turning on the fan 17 to generate suction, the exhaust gas is drawn in through the air inlet 11. As the exhaust gas passes under the water mist nozzle 15, the liquid in the water tank 12 enters the water outlet 14 through the connecting pipe 13 and is sprayed out from the water mist nozzle 15 as a water mist. When the exhaust gas passes through the activated carbon plate 16, the activated carbon plate 16 adsorbs gases such as toluene in the exhaust gas. After the exhaust gas is treated, it is discharged from the air outlet of the fan 17. 5. The sprayed water mist adheres to the paint particles or dust in the spray exhaust gas, forming water droplets that fall into the recovery port 2, landing on the surface of the first slide plate 24. The droplets slide down its inclined surface onto the filter plate 22 for separation, and return to the water tank 12. The paint particles or dust on the filter plate 22 slide down its inclined surface to the middle of the collection box 23. Once the collection box 23 is full, it is removed for cleaning. The guide hood 3 reduces the diffusion of the spray exhaust gas, causing it to flow along the inner wall of the guide hood 3. The central guide cone 3... 2. By dividing the spray exhaust gas through the cone surface, the low-pressure vortex formed in the central area of ​​the guide hood 3 is reduced. At the same time, the airflow is evenly guided to the surrounding area. The power is turned on, and the current is transmitted to the surface of the electrostatic grid 4 through the connecting wire 41, so that the surface of the electrostatic grid 4 is filled with an electrostatic field, which adsorbs larger particles in the spray exhaust gas, reducing the blockage of filter plate 22 or activated carbon plate 16 by larger particles. After the power is turned off, the particles adsorbed by the electrostatic grid 4 slide down the inner wall of the guide hood 3. After the activated carbon plate 16 reaches saturation, the heating rod 51 is turned on to heat the activated carbon plate 16, remove the moisture in the adsorbed material, reduce its volume, and detach it from the pores of the activated carbon plate 16. The detached adsorbed material falls into the feed port 52, slides down the second slide plate 53, and slides out from the discharge port 54 into the collection box 23. The silicone pad 6 fills the gap between the electrostatic grid 4 and the treatment box 1, and at the same time uses its own material to intercept the electrostatic grid 4. The above shows and describes the basic principle, main features and advantages of this utility model.
