Description

Technical Field

[0001] This invention relates to the field of environmentally friendly emissions of waste gas, and specifically to an environmentally friendly emission treatment device with a horizontal cyclone collector. Background Technology

[0002] A spray booth is a work area specifically designed for spray painting operations. During the spraying process, some paint mist floats in the spraying environment. Therefore, the exhaust gas generated in the spray booth needs to be purified before being discharged. This serves two purposes: firstly, it protects the atmospheric environment by minimizing emissions, and secondly, it allows for the recycling and reuse of paint mist, preventing waste.

[0003] The essence of paint mist recovery is gas-solid separation. Currently, the mainstream technologies are divided into two main categories: "dry" and "wet." Dry recovery methods capture paint mist through physical filter materials. For example, air containing paint mist is drawn into the filtration system by a fan, undergoes multiple filtrations to adsorb and capture paint mist particles, and is then purified before being discharged. Its advantages include waterless treatment, low energy consumption, and dry recovered paint residue. However, it also has some drawbacks. Specifically, because paint mist particles adhere to the surface of the filter material during capture, the filter material needs to be replaced periodically, or it needs to be removed, cleaned of the paint mist particles, and reinstalled for continued use. Regardless of the method, a pause is required, which reduces efficiency.

[0004] Based on the above problems, the present invention proposes an environmentally friendly emission treatment device with a horizontal cyclone recovery unit. Summary of the Invention

[0005] To address the problems mentioned in the background above, the present invention provides an environmentally friendly emission treatment device with a horizontal cyclone recovery unit.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows.

[0007] An environmentally friendly emission treatment device with a horizontal cyclone collector includes a frame, on which a filter capture assembly is installed. The filter capture assembly includes a vertically arranged cylindrical shell. A rectangular step is provided at the upper opening end of the cylindrical shell. A chute is provided on one side of the rectangular step. The upper opening of the cylindrical shell is located on the lower wall of the chute. A cover plate is provided on the upper surface of the rectangular step. An air inlet and an air outlet are provided on the end face of the cover plate. An air inlet pipe is provided at the opening of the air inlet, and an air outlet pipe is provided at the opening of the air outlet. A blower is provided at the end of the air outlet pipe.

[0008] A sliding plate is installed inside the chute. The sliding plate has mounting holes. There are two mounting holes along the depth of the chute. The two mounting holes can be coaxially connected to the air inlet and air outlet respectively. A filter screen is installed in both mounting holes.

[0009] A connecting valve is installed at the bottom of the shell.

[0010] As a further improvement and optimization of the present invention, the diameters of the mounting hole, the air inlet hole and the air outlet hole are the same.

[0011] As a further improvement and optimization of the present invention, the lower surface of the slide plate is provided with a protrusion 1 and a protrusion 2. The protrusion 2 is located between two mounting holes. Initially, one mounting hole is coaxial with the air outlet, and the other mounting hole is located outside the slide groove. At this time, the protrusion 2 is in contact with the inner wall of the upper cylindrical section. When the two mounting holes are coaxial with the air outlet and the air inlet respectively, the protrusion 1 is in contact with the outer surface of the upper cylindrical section.

[0012] As a further improvement and optimization of the present invention, the cylindrical shell is divided into a lower frustum section, a middle cylindrical section and an upper cylindrical section from bottom to top along the axial direction. The diameter of the lower frustum section increases from bottom to top. The diameter of the middle cylindrical section is larger than that of the upper cylindrical section and a shoulder is formed between the two. An isolation plate is provided in the middle cylindrical section through an inner support. The isolation plate is coaxial with the cylindrical shell. The outer circular surface of the isolation plate is close to the inner wall of the middle cylindrical section, and the upper surface of the isolation plate is close to the shoulder.

[0013] As a further improvement and optimization of the present invention, a motor is provided at the bottom of the isolation plate. The output end of the motor passes through the clearance hole provided on the isolation plate and is provided with a cleaning fan blade. The cleaning fan blade includes a number of blades arranged in a circumferential direction at the output end of the motor. The lower surface of the blade is in contact with the upper surface of the isolation plate. When the motor drives the cleaning fan blade to rotate, the cleaning fan blade can pull the particles to move towards the gap between the isolation plate and the inner wall of the middle cylindrical section.

[0014] As a further improvement and optimization of the present invention, a cyclone recovery device is provided at the air outlet end of the blower.

[0015] As a further improvement and optimization of the present invention, an electrostatic adsorption component is provided at the output end of the cyclone recovery unit.

[0016] As a further improvement and optimization of the present invention, the electrostatic adsorption component includes a mounting shell, and an input pipe and an output pipe are respectively provided on two sides along the length direction of the mounting shell, and the input pipe is connected to the output end of the cyclone collector.

[0017] The bottom of the mounting housing is provided with a base plate, and the upper surface of the base plate is provided with a partition plate. Multiple partition plates are arranged in an array along the length of the mounting housing. The base plate and multiple partition plates together form a discharge electrode.

[0018] Dust collection units are installed between two adjacent partition plates, between the partition plate closest to the input pipe and the inner wall of the mounting shell where the input pipe is located, and between the partition plate closest to the output pipe and the inner wall of the mounting shell where the output pipe is located.

[0019] As a further improvement and optimization of the present invention, the dust collection unit includes two rotating rollers distributed vertically and a dust collection pole disposed between the two rotating rollers. The axis of the rotating rollers is parallel to the width direction of the mounting shell. The rotating rollers are made of insulating material, and the dust collection pole is made of spiral steel strips.

[0020] As a further improvement and optimization of the present invention, the input end of any one of the rotating rollers of the dust collection unit extends out of the mounting shell and is poweredly connected to a motor.

[0021] The dust collection unit has an inclined scraper on the side away from the output pipe, and the scraper is in contact with the outer surface of the dust collection electrode.

[0022] Compared with the prior art, the beneficial effects of this invention are as follows:

[0023] Technical effect 1: In this case, the air inlet and outlet are arranged in parallel to each other, creating a U-shaped airflow trajectory. Under the action of gravity, most paint mist particles will fall directly downwards, which can greatly reduce the capture burden of the filter and the burden of frequent cleaning of the filter. A small number of paint mist particles are captured by the filter when passing through it. Therefore, the combination of the two can greatly improve the effect of the first capture of paint mist particles.

[0024] Technical effect 2: Pushing the slide plate causes the paint mist particles captured and attached to the filter to be backwashed by the paint mist exhaust gas, thus achieving rapid and efficient cleaning of the filter, and the treatment of paint mist exhaust gas does not need to be interrupted.

[0025] Technical Effect 3: Filter screens generally possess elasticity. When filtering and capturing paint mist particles, the paint mist exhaust gas passes through the filter screen from bottom to top, therefore the filter screen bulges upwards. During filter cleaning, the paint mist exhaust gas backflows through the filter screen from top to bottom, therefore the filter screen bulges downwards. The two bulge directions are opposite, thus promoting the removal of stubborn paint mist particles attached to and stuck on the filter screen, further improving the efficiency of filter cleaning. Furthermore, during filter cleaning, the sliding plate can be quickly and repeatedly pushed and pulled, allowing the filter screen to rapidly switch between the air inlet and outlet, ensuring continuous upward and downward bulges, further guaranteeing the effective removal of stubborn paint mist particles.

Detailed Implementation

[0036] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0037] Reference Figures 1-8 An environmentally friendly emission treatment device with a horizontal cyclone recovery unit includes a frame 100, on which a filter capture assembly 200, a cyclone recovery assembly 300, and an electrostatic adsorption assembly 400 are installed.

[0038] I. The filter capture component 200 uses a dry recovery method to perform the first stage of paint mist particle capture in the paint mist exhaust gas. Specifically:

[0039] Reference Figures 3-6The filter capture assembly 200 includes a cylindrical shell 201, which is arranged vertically and is divided into a lower frustum section 2011, a middle cylindrical section 2012, and an upper cylindrical section 2013 from bottom to top along the axis. The diameter of the lower frustum section 2011 increases from bottom to top. The diameter of the middle cylindrical section 2012 is larger than that of the upper cylindrical section 2013, and a shoulder is formed between the two. An isolation plate 2015 is provided in the middle cylindrical section 2012 through an inner support 2014. The isolation plate 2015 is coaxial with the cylindrical shell 201. The outer circular surface of the isolation plate 2015 is close to the inner wall of the middle cylindrical section 2012, and the upper surface of the isolation plate 2015 is close to the shoulder.

[0040] A motor 210 is provided at the bottom of the isolation plate 2015. The output end of the motor 210 passes through the clearance hole provided on the isolation plate 2015 and is provided with a cleaning fan blade 211. The cleaning fan blade 211 includes a number of blades arranged in a circumferential direction at the output end of the motor 210. The lower surface of the blades is in contact with the upper surface of the isolation plate 2015. When the motor 210 drives the cleaning fan blade 211 to rotate, the cleaning fan blade 211 can pull the particles to move towards the gap between the isolation plate 2015 and the inner wall of the middle cylindrical section 2012.

[0041] A connecting valve 202 is provided at the bottom of the shell 201.

[0042] A rectangular step 203 is provided at the upper opening end of the cylindrical shell 201, and a sliding groove 2031 is provided on one side of the rectangular step 203. The upper opening of the cylindrical shell 201 is located on the lower groove wall of the sliding groove 2031.

[0043] A cover plate 204 is provided on the upper surface of the rectangular step 203. An air inlet 2041 and an air outlet 2042 are provided on the end face of the cover plate 204. An air inlet pipe 205 is provided at the opening of the air inlet 2041. Paint mist exhaust gas enters the cylinder shell 201 through the air inlet pipe 205. An air outlet pipe 206 is provided at the opening of the air outlet 2042. A blower 207 is provided at the end of the air outlet pipe 206. The air outlet end of the blower 207 is connected to the input end of the cyclone recovery component 300.

[0044] A slide plate 208 is slidably disposed in the slide groove 2031. The slide plate 208 is provided with mounting holes. There are two mounting holes along the groove depth direction of the slide groove 2031. The two mounting holes can be coaxially connected to the air inlet 2041 and the air outlet 2042 respectively. Furthermore, the diameters of the mounting holes, the air inlet 2041 and the air outlet 2042 are the same.

[0045] A filter screen 209 is installed in both mounting holes.

[0046] The working process of the filter capture component 200 is as follows:

[0047] Initially, one mounting hole is coaxial with the air outlet 2042 and is named mounting hole a; the other mounting hole is located outside the slide groove 2031 and is named mounting hole b, as shown below. Figure 3 and Figure 5 As shown;

[0048] The process of filtering and capturing paint mist particles is as follows: the blower 207 is started, and the paint mist exhaust gas enters the cylinder shell 201 through the air inlet pipe 205 and the air inlet hole 2041. Then it passes through the filter screen 209 in the mounting hole a, and enters the cyclone recovery assembly 300 through the air outlet hole 2042, the air outlet pipe 206 and the blower 207. During this process, the paint mist particles are captured by the filter screen 209 in the mounting hole a.

[0049] After a preset time, a large number of paint mist particles will inevitably be captured and attached to the filter screen 209 in the mounting hole a. At this time, the sliding plate 208 is pushed inward manually to make the mounting hole a coaxial with the air inlet 2041 and the mounting hole b coaxial with the air outlet 2042. The paint mist exhaust gas passes through the filter screen 209 in the mounting hole a from top to bottom, realizing the backflushing and cleaning of the filter screen 209 in the mounting hole a. Since the filter screen 209 in the mounting hole b is present, the treatment of paint mist exhaust gas does not need to be paused. After a few seconds, the sliding plate 208 is pulled outward to make the mounting hole a coaxial with the air outlet 2042 again.

[0050] In addition, the paint mist particles are pushed into the lower truncated section 2011 by the cleaning fan blades 211. With the cooperation of the shoulder and the isolation plate 2015, the paint mist particles in the lower truncated section 2011 will not be affected by the airflow and fly around randomly. When there are a lot of paint mist particles in the lower truncated section 2011, the connecting valve 202 is opened to discharge the paint mist particles.

[0051] Its technological advantages lie in:

[0052] Technical effect 1: In this case, the air inlet 2041 and the air outlet 2042 are arranged in parallel to each other, forming a U-shaped airflow trajectory. Under the action of gravity, most of the paint mist particles will fall directly downwards, which can greatly reduce the capture burden of the filter 209 and the burden of frequent cleaning of the filter 209. A small number of paint mist particles are captured by the filter 209 when passing through it. Therefore, the combination of the two can greatly improve the effect of the first capture of paint mist particles.

[0053] Technical effect 2: Pushing the slide plate 208 causes the paint mist particles captured and attached to the filter screen 209 to be backwashed by the paint mist exhaust gas, thus enabling rapid and efficient cleaning of the filter screen 209, and the treatment of paint mist exhaust gas does not need to be interrupted.

[0054] Technical Effect 3: The filter screen 209 generally has elastic properties. When filtering and capturing paint mist particles, the paint mist exhaust gas passes through the filter screen 209 from bottom to top, so the filter screen 209 is convex upwards. When cleaning the filter screen 209, the paint mist exhaust gas backflows from top to bottom, so the filter screen 209 is convex downwards. The two convex directions are opposite, which can promote the removal of stubborn paint mist particles attached to the filter screen 209, thus further improving the efficiency of cleaning the filter screen 209. Furthermore, when cleaning the filter screen 209, the sliding plate 208 can be pushed and pulled quickly and repeatedly, allowing the filter screen 209 to quickly switch between the air inlet 2041 and the air outlet 2042, so that the upward and downward convexity is continuous, further ensuring the effective removal of stubborn paint mist particles.

[0055] In a preferred embodiment, when pushing or pulling the sliding plate 208, to ensure that the mounting hole is accurately positioned below the air inlet 2041 or air outlet 2042, refer to... Figure 5 and Figure 6 The lower surface of the slide plate 208 is provided with a protrusion 2081 and a protrusion 2082, with the protrusion 2082 located between two mounting holes.

[0056] Initially, one mounting hole is coaxial with the air outlet 2042 and is named mounting hole a. The other mounting hole is located outside the slide groove 2031 and is named mounting hole b. At this time, the second protrusion 2082 is in contact with the inner wall of the upper cylindrical section 2013.

[0057] When the two mounting holes are coaxial with the air outlet 2042 and the air inlet 2041 respectively, the protrusion 2081 contacts the outer surface of the upper cylindrical section 2013.

[0058] Thus, by cooperating with protrusion 1 2081 and protrusion 2082, when pushing or pulling the sliding plate 208, the operator only needs to push or pull the sliding plate 208. When a large resistance is felt when pushing or pulling, protrusion 1 2081 or protrusion 2082 needs to contact the upper cylindrical section 2013 to restrict pushing or pulling. At this time, the position of the mounting hole is just coaxial with the air inlet 2041 or air outlet 2042.

[0059] II. Cyclone Recovery Component 300:

[0060] Reference Figure 2 The cyclone recovery assembly 300 includes a cyclone recoverer. The input end of the cyclone recoverer is connected to the outlet end of the blower 207, and the output end of the cyclone recoverer is connected to the input end of the electrostatic adsorption assembly 400. The cyclone recoverer is a technology that can be implemented in the prior art and will not be described in detail. The cyclone recoverer is used as a second treatment structure for paint mist exhaust gas to further improve the thoroughness of paint mist particle recovery.

[0061] III. The electrostatic adsorption component 400 uses electrostatic adsorption technology to perform a third stage of treatment on the paint mist exhaust gas, removing dust and other impurities from the exhaust gas:

[0062] Reference Figure 7 and Figure 8 The electrostatic adsorption component 400 includes a mounting shell 401. An input pipe 402 and an output pipe 403 are respectively provided on two sides along the length direction of the mounting shell 401. The input pipe 402 is connected to the output end of the cyclone collector, and the output pipe 403 is used to discharge waste gas to the outside.

[0063] The bottom of the mounting housing 401 is provided with a base plate 404, and the upper surface of the base plate 404 is provided with a partition plate 405. Multiple partition plates 405 are arranged in an array along the length direction of the mounting housing 401. The base plate 404 and the multiple partition plates 405 together form a discharge electrode.

[0064] Dust collection units are provided between two adjacent partition plates 405, between the partition plate 405 closest to the input pipe 402 and the inner wall of the mounting shell 401 where the input pipe 402 is located, and between the partition plate 405 closest to the output pipe 403 and the inner wall of the mounting shell 401 where the output pipe 403 is located.

[0065] The dust collection unit includes two rotating rollers 406 arranged vertically and a dust collection electrode 407 disposed between the two rotating rollers 406. The axis of the rotating rollers 406 is parallel to the width direction of the mounting housing 401. The rotating rollers 406 are made of insulating material, and the dust collection electrode 407 is made of conductive material and is flexible, such as using a spring, i.e., a spiral steel bar.

[0066] A scraper 408 is provided on the side of the dust collection unit away from the output pipe 403 and is arranged at an angle. The scraper 408 is in contact with the outer surface of the dust collection electrode 407.

[0067] The input end of any one of the rollers 406 extends out of the mounting shell 401 and is powered by a motor 409.

[0068] The working process of the electrostatic adsorption component 400 is as follows:

[0069] The exhaust gas flows into the mounting housing 401 through the input pipe 402 and flows along the channel separated by the partition plate 405. During the flow, the dust and particulate matter in the exhaust gas are adsorbed onto the outer surface of the dust collection electrode 407 by the principle of electrostatic dust removal. Then the exhaust gas is discharged through the output pipe 403.

[0070] In the above process, motor 409 drives the rotating roller 406 to rotate, causing the dust collecting electrode 407 to move. The dust collecting electrode 407 is then scraped and cleaned by scraper 408. Scraper 408 is made of insulating material to ensure the high efficiency of electrostatic dust removal.

[0071] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
