Description

Technical Field

[0001] The invention relates to the technical field of volatile organic waste gas treatment, and in particular to a volatile organic waste gas comprehensive treatment device. Background Art

[0002] Volatile organic compounds are a class of organic compounds with high vapor pressure and are easy to evaporate. There are more than 300 types of them, mainly including alkanes, alkenes, aromatics, halogenated hydrocarbons, ketones, esters, etc. As the core precursors of air pollution, their sources are extensive and complex, posing multiple threats to the environment and human health.

[0003] Volatile organic waste gas exists in various technical fields and engineering fields. For example, the volatile organic waste gas generated by automobile painting and ship painting has the characteristics of high concentration, large air volume and complex composition. Although activated carbon adsorption technology can effectively reduce the emission concentration, it has problems such as limited adsorption capacity, difficult regeneration and high maintenance cost. The present invention is to provide a comprehensive treatment device for volatile organic waste gas to alleviate the above technical problems in the prior art. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that the volatile organic compound waste gas generated in the engineering field, such as automobile spray painting and ship painting, has the characteristics of high concentration, large air volume and complex composition. Although the activated carbon adsorption technology can effectively reduce the emission concentration, it has the problems of limited adsorption capacity, difficult regeneration and high maintenance cost, and a volatile organic compound waste gas comprehensive treatment device is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A volatile organic compound waste gas comprehensive treatment device comprises a base, wherein a gear sleeve is rotatably connected to the top of the base, a fixed box is fixedly connected to the top of the gear sleeve, a treatment box is slidably connected to the inside of the fixed box, an inner gear of the box is rotatably connected to the bottom of the treatment box, the inner gear of the box is meshedly connected to a rack in the box, an end of the rack in the box away from the inner gear of the box is fixedly connected to an activated carbon plate, a rotating gear rod is fixedly connected to the top of the inner gear of the box, the rotating gear rod is meshedly connected to a second rack, the second rack is fixedly connected to a second discharge contact plate, the rotating gear rod is meshedly connected to a first rack, the first rack is fixedly connected to a first discharge contact plate, the bottom of the inner gear of the box passes through the treatment box and is fixedly connected to a second bevel gear, the second bevel gear is meshedly connected to a first bevel gear, the first bevel gear is transmission-connected to a connecting rod, the connecting rod is transmission-connected to a first threaded rod, the end of the connecting rod away from the first threaded rod is transmission-connected to a second threaded rod, the first threaded rod is threadedly connected to a first stopper, and the second threaded rod is transmission-connected to a second stopper.

[0006] The above technical solution further includes: The first bevel gear is sleeved outside the support rod, the support rod is rotatably connected to the connection block, the support rod is drivingly connected to a third belt, one end of the third belt away from the connection block is drivingly connected to a connecting rod, the connecting rod is drivingly connected to a first belt, the first belt is drivingly connected to a first threaded rod, the connecting rod is drivingly connected to a second belt, and the second belt is drivingly connected to a second threaded rod.

[0007] A seat gear is rotatably connected above the base, the seat gear is meshed with the outer wall of the gear sleeve, a hole for connecting a pipeline is provided at the bottom of the fixed box, one end of the pipeline away from the fixed box is fixedly connected to a micro catalytic combustion box, the micro catalytic combustion box is fixed above the base, and an exhaust pipe is provided on the side of the micro catalytic combustion box.

[0008] A volatile organic compound waste gas concentration detection block is provided above the fixed box, and the volatile organic compound waste gas concentration detection block is used for detecting the waste gas concentration in the current area.

[0009] A slide rail is provided inside the fixed box, and a processing box is slidably connected to the slide rail.

[0010] A round hole is opened at the bottom of the processing box, and the round hole is used for connecting to the opening of the pipeline.

[0011] A plurality of conductive screw rods are arranged inside the activated carbon plate, and the conductive screw rods are used for the contact between the first discharge contact plate and the second discharge contact plate. The conductive screw rods can accurately contact the first discharge contact plate and the second discharge contact plate, providing a reliable connection method for the electrified regeneration of the activated carbon plate. When the activated carbon plate adsorbs waste gas to reach the saturation state, through this precise conductive contact, the activated carbon plate can be quickly electrified and heated. This enables the volatile organic compounds adsorbed on the activated carbon plate to quickly overflow, improving the regeneration efficiency of the activated carbon plate, thereby ensuring that the device can continuously and stably adsorb and process waste gas. In addition, the arrangement of a plurality of conductive screw rods can also make the activated carbon plate heat more evenly, further improving the desorption effect, extending the service life of the activated carbon plate, and reducing the replacement cost.

[0012] A fan for allowing waste gas to enter and exit the round hole is provided above the processing box. The fan provided above the processing box plays a crucial role in promoting the entire waste gas treatment process. When the activated carbon plate is electrified and heated to cause the waste gas to overflow, the fan can quickly and effectively blow these high-concentration waste gases into the round hole and then enter the subsequent treatment links. This active waste gas transportation method greatly improves the flow rate of waste gas inside the device, reduces the residence time of waste gas in the processing box, and avoids the risk of secondary pollution caused by waste gas accumulation.

[0013] The interior of the fixed box is provided with a first square groove for placing the first stop block, and the interior of the fixed box is provided with a second square groove for placing the second stop block. The first square groove and the second square groove provided inside the fixed box have important practical values. The first square groove is used to place the first stop block, and the second square groove is used to place the second stop block. During the operation of the device, when operations such as power-on regeneration of the activated carbon plate are required, the first stop block and the second stop block can be moved and stored as needed.

[0014] The connecting rod is rotatably connected to the fixed plate, and a blower is provided outside the treatment box. The connecting rod is rotatably connected to the fixed plate, and a blower is provided outside the treatment box. The coordinated work of these components makes the entire waste gas treatment system more flexible and stable. The rotational connection between the connecting rod and the fixed plate provides a certain degree of flexibility for the transmission structure inside the device, enabling better coordination among the various transmission components, reducing energy loss during transmission, and the probability of failures.

[0015] The present invention has the following beneficial effects: 0. In the present invention, through the integration of the electric heating desorption technology and the micro catalytic combustion system, the limitations of the traditional activated carbon adsorption technology are broken through. When the activated carbon plate is saturated with adsorption, it is electrically heated through the conductive lead screw and the discharge contact plate, enabling the rapid desorption of the adsorbed volatile organic compounds, avoiding the cumbersome process of manual carbon plate replacement. The desorbed high-concentration waste gas is directly introduced into the micro catalytic combustion box and decomposed into carbon dioxide and water under the action of the catalyst, achieving harmless treatment. This design not only reduces the replacement frequency of the activated carbon, extends the service life of the carbon plate, but also eliminates the need for external treatment equipment for the desorbed waste gas, reducing the risk of secondary pollution.

[0016] 1. In the present invention, the device real-time monitors the ambient concentration through the volatile organic compound waste gas concentration detection block and drives the rollers at the base to automatically move to the high-concentration area to achieve precise adsorption. The gear and rack in the gear and rack transmission system box ensure the dynamic switching and regeneration of the activated carbon plate, maintaining a stable adsorption efficiency. The modular design enables the device to be flexibly deployed at different workstations such as spray paint rooms and welding areas without fixed pipelines, adapting to the complex layout of the engineering site. For temporary scenarios such as municipal engineering and emergency repairs, the device can respond quickly, covering dispersed emission sources. In addition, the integrated design of the micro catalytic combustion box and the treatment box compresses the volume of the device to that of the traditional device, combining high-efficiency treatment capabilities with portability.

When the activated carbon plate 8 is energized and heated to cause the waste gas to overflow, the fan can quickly and effectively blow these high-concentration waste gases into the inside of the round hole 20, and then enter the subsequent treatment links.

[0031] In this embodiment, the first square groove 13 and the second square groove 14 opened inside the fixed box 5 have important practical values. The first square groove 13 is used to place the first stopper 12, and the second square groove 14 is used to place the second stopper 15. During the operation of the device, when it is necessary to perform operations such as energized regeneration on the activated carbon plate 8, the first stopper 12 and the second stopper 15 can be moved and stored as needed.

[0032] In one embodiment, for the above-mentioned connecting rod 21 and fixed plate 22, the connecting rod 21 is rotatably connected to the fixed plate 22, and a blower 35 is provided outside the processing box 10.

[0033] In this embodiment, the connecting rod 21 is rotatably connected to the fixed plate 22, and a blower 35 is provided outside the processing box 10. The coordinated operation of these components makes the entire waste gas treatment system more flexible and stable. The rotational connection between the connecting rod 21 and the fixed plate 22 provides a certain degree of flexibility to the transmission structure inside the device, enabling better coordination between the various transmission components, reducing energy loss during transmission and the probability of faults occurring.

[0034] The working principle of a volatile organic compound waste gas comprehensive treatment device in the present invention is as follows: First, it moves to the place where volatile organic compounds need to be absorbed by means of the rollers at the bottom of the base 1. At this time, the blower 35 is started, and the blower 35 will absorb the volatile organic waste gas in the air. Then, the absorbed gas passes through the activated carbon plate 8 and is thus absorbed. After a period of absorption, since the absorption capacity of the activated carbon plate 8 is limited, at this time, the gear 28 inside the control box can be rotated. The rotation of the gear 28 inside the box will engage with the second rack 31 and the first rack 30, so that the second discharge contact plate 34 and the first discharge contact plate 33 approach each other. As the gear 28 inside the box rotates, the gear 28 inside the box engages with the rack 29 inside the box, causing the activated carbon plate 8 to gradually approach the gear 28 inside the box.

[0035] Meanwhile, the rotation of the gear 28 inside the box drives the second bevel gear 27 at the bottom to rotate. The rotation of the second bevel gear 27 meshes with the first bevel gear 26 to drive the support rod 25 to rotate. The support rod 25 then drives the connecting rod 21 to rotate by means of the third belt 23, so as to drive the first belt 17 and the second belt 19 to transmit power. The rotation of the first belt 17 drives the first threaded rod 16 to rotate, and the rotation of the second belt 19 drives the second threaded rod 18 to rotate. The rotation of the first threaded rod 16 causes the second stop block 15 and the first stop block 12 to approach each other to form a complete whole. At the same time, the rack 29 inside the box drives the activated carbon plate 8 to move, so that the second discharge contact plate 34 and the first discharge contact plate 33 on both sides are attached to the surface of the conductive screw rod 9 on the side of the activated carbon plate 8, thereby energizing the entire activated carbon plate 8. At this time, inside the treatment box 10, the volatile organic compound waste gas absorbed by the activated carbon plate 8 overflows due to being heated by electricity. The concentration of the overflowed waste gas is much higher than that of the external waste gas. Then, the fan inside the treatment box 10 is started to blow the waste gas into the round hole 20. The waste gas passes through the gear sleeve 4 inside the pipe 3 from the round hole 20 and finally reaches the inside of the micro catalytic combustion box 2. The waste gas becomes harmless substances such as carbon dioxide and water after passing through the micro catalytic combustion box 2. When the concentration of the volatile organic compound waste gas in a part of the space is low, it can be detected by the volatile organic compound waste gas concentration detection block 7, and then move to a higher area by means of the rollers at the bottom of the base 1 to fully absorb the waste gas.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
