Description

Technical Field

[0001] The present invention relates to the technical field of waste gas purification, and in particular to a composite photocatalytic plasma waste gas purification device and a purification method thereof. Background Art

[0002] In real life, waste gas sources of foul odors are numerous and come from a wide range of sources, primarily the heating or combustion of organic matter, the volatilization of organic solvents, and the treatment of waste liquids and residues from meat processing. Leather factories, paint plants, electroplating plants, chemical plants, pulp and paper mills, slaughterhouses, and garbage stations are all sources of foul odor pollution.

[0003] With the development of science and technology, there are many ways to treat waste gas. In some small treatment institutions, most of them use photocatalytic plasma equipment to treat waste gas, using light to irradiate the waste gas to degrade it. Although it is easy to use, it still has obvious defects in daily use, such as:

[0004] In current photocatalytic plasma equipment, the irradiation lamps are generally installed inside the equipment. When the exhaust gas flows inside the equipment, it will come into contact with the surface of the lamp posts, thereby attaching a large amount of stains to the surface. Therefore, staff need to clean them. However, because the lamp posts are installed densely and are located inside the equipment, cleaning and maintenance are too cumbersome and inconvenient.

[0005] Therefore, a composite photocatalytic plasma waste gas purification device and a purification method thereof that can be easily cleaned and maintained are now designed to solve such defects. Summary of the Invention

A rectangular seat for use with the sealing slot is installed on the front and rear sides of the bottom of the inner cavity of the concave notch, a plug-in slot is provided on the top of the plug-in slot, and a plurality of plug-in slots are provided, and a lamp tube column for use with the plug-in slot is fixedly installed on the top of the inner cavity of the sealing frame.

[0008] Preferably, the top of the sealing frame is fixedly connected to a lifting frame through a fixing block, and both sides of the rear portion of the purification treatment box surface are fixedly connected to electric telescopic rods through fixing blocks, and the top of the electric telescopic rod is fixedly connected to the bottom of the lifting frame.

[0009] Preferably, the surfaces of several of the lamp tube columns are sleeved with porous scrapers, and side pressure plates are fixedly connected on both sides of the porous scraper. Positioning slots are provided on the side of the side pressure plates away from the porous scraper. Guide grooves are provided on both sides of the front and rear of the porous scraper, and guide rails are fixedly installed on both sides of the front and rear of the inner cavity of the sealing frame for use with the guide grooves.

[0010] Preferably, the front and rear parts of the side pressure plate away from the porous scraper are both slidably installed with retraction rods through openings, and the front and rear parts of both sides of the sealing frame are provided with anti-slip grooves, and the inner side of the anti-slip groove is slidably installed with a slider plate, and the slider plate is fixedly connected to the retraction rod, and the surface of the retraction rod is provided with a spring.

[0011] Preferably, the front and rear parts of both sides of the top of the purification treatment box are fixedly connected to the guide sliding frame through a fixed plate, and a load-bearing connecting plate is slidably installed between the inner sides of the two guide sliding frames on the same side, and the front and rear sides of the top of the load-bearing connecting plate are fixedly connected to the limiting rod through a fixed block.

[0012] Preferably, an upper top plate is slidably installed between the surfaces of the two limit rods, the top of the upper top plate is threadedly connected to a threaded rod through an opening, and the bottom end of the threaded rod is rotatably connected to the top of the load-bearing connecting plate through a bearing member, and the opposite sides of the two upper top plates are fixedly connected with an arc plug plate used in conjunction with the positioning slot.

[0013] Preferably, a mounting frame is fixedly installed on the right side of the inner cavity of the purification treatment box, an activated carbon plate is installed on the inner side of the mounting frame, and the front and rear parts of the left side of the mounting frame are slidably installed with pressing columns used in conjunction with the activated carbon plate through openings, a vertical connecting plate is fixedly connected between the left ends of the two pressing columns on the same side, an arc-shaped pressure seat is fixedly installed on the left side of the vertical connecting plate, and extrusion blocks used in conjunction with the arc-shaped pressure seat are fixedly connected on both sides of the bottom of the sealing frame.

[0014] Preferably, ventilation covers are fixedly installed on both sides of the purification treatment box through openings.

[0015] A method for purifying composite photocatalytic plasma waste gas, specifically comprising the following steps:

[0016] S1. Connect two ventilation hoods to the pipes, then start several lamp columns. After the exhaust gas enters the purification treatment box through the pipes and ventilation hoods, the light emitted by the several lamp columns catalyzes and degrades the exhaust gas. The degraded exhaust gas will pass through the activated carbon plate again to be filtered and discharged;

[0017] S2. When maintaining and cleaning the lamp column, several electric telescopic rods are started to lift the sealing frame from the inside of the concave groove. After the sealing frame is lifted, several lamp columns are pulled out from the inside of the plug-in slot and rise together. Then the staff pushes the load-bearing connecting plate to move under the limit of the guide slide frame. When the two load-bearing connecting plates are moved close to the sealing frame, they stop. At this time, the arc plug-in plate is inserted into the positioning slot. After the arc plug-in plate is inserted into the positioning slot, the upper plate squeezes the two retraction rods to push the slider plate out of the anti-slip slot. Then the staff rotates the two threaded rods at the same time. Driven by the limit rod, the upper plate is driven by the arc plug-in plate to drive the porous scraper to move up and down, thereby scraping off the stains on the surface of the lamp column.

[0018] S3. At the same time, replace the damaged lamp column, pull the vertical connecting plate and the pressing column to the left from the installation frame at the concave groove. At this time, the activated carbon board is loosened, and then the activated carbon board is cleaned. After all structures are cleaned, restart the electric telescopic rod to lower the sealing frame and re-dock it with the concave groove. At the same time, the lamp column is inserted into the inside of the socket and fixed. During the docking process, the extrusion block will squeeze the two arc-shaped pressure seats, thereby pushing the pressing column to squeeze and fix the activated carbon board, and then it can be used again.

[0019] Beneficial effects

[0020] The present invention provides a composite photocatalytic plasma waste gas purification device and purification method. Compared with existing technologies, it has the following advantages:

[0021] (1) The composite photocatalytic plasma waste gas purification equipment and purification method thereof are characterized by installing a concave notch on the top of the purification treatment box and installing a sealing frame on the inner side of the concave notch, and a plurality of lamp posts are installed on the top of the inner cavity of the sealing frame, and are used in conjunction with a top plate and an arc plug plate. The arrangement of these structures can directly lift the sealing frame through the electric telescopic rod when cleaning the lamp posts, and use the arc plug plate to quickly clean the surface of the lamp posts by connecting with the positioning notch, and at the same time facilitate the maintenance and replacement of damaged lamp posts, thereby facilitating use.

[0022] (2) The composite photocatalytic plasma waste gas purification equipment and purification method thereof are characterized by installing an installation frame on the right side of the inner cavity of the purification treatment box and installing an activated carbon plate inside the installation frame, and using the installation frame in conjunction with an arc-shaped pressure seat and an extrusion block. The activated carbon plate can further adsorb the waste gas, and the separation of the extrusion block and the arc-shaped pressure seat can facilitate the replacement and maintenance of the activated carbon plate by the staff. At the same time, the sealing frame and the concave groove can be connected to squeeze the arc-shaped pressure seat to allow the pressing column to fix the activated carbon plate, thereby reducing the direct operation of the staff and meeting the current use.
