[0003] The existing patent with authorization announcement number "CN201922400571.5" discloses an activated carbon adsorption photocatalytic purification device. Activated carbon adsorption and photocatalysis are used simultaneously inside the device. Impurities in the medium are adsorbed by molecules on the pore walls of the activated carbon fibers. If the activated carbon is not replaced in time, it will cause excessive harmful substances and impurities in the air, affecting the efficiency of photocatalysis, resulting in a higher content of harmful substances in the gas finally discharged. However, due to the influence of the air flow rate at the air inlet, the degree of adsorption of activated carbon inside the exhaust gas treatment device is different, and it is impossible to better judge whether the activated carbon still has an adsorption effect. Usually, the activated carbon plate is replaced as a whole, and the resource utilization rate is low.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0022] A waste gas purification photocatalytic device, such as Figure 1 - Figure 4 As shown, it includes a box body 1, which includes an air inlet 2, an air outlet, an activated carbon filter assembly 3 and an ultraviolet lamp 4 assembly. The side wall of the box body 1 is provided with a plurality of box doors 101. A slide rail 5 is fixedly connected to the box body 1. The activated carbon filter assembly 3 is slidably connected to the slide rail 5. The activated carbon filter assembly 3 includes a plate body 301 and a plurality of activated carbon pieces. The plate body 301 is provided with a plurality of movable through-holes 302. The activated carbon pieces are inserted into the movable through-holes 302 and slide vertically up and down in the through-holes. The top and bottom of the activated carbon piece are respectively fixedly connected with a spring 1 303 and a spring 2 304. Spring 1 303 is fixedly connected to the top of the movable through-hole 302, and spring 2 304 is fixedly connected to the bottom of the movable through-hole 302. Spring 1 303 and spring 2 304 make the activated carbon piece located at the center of the movable through-hole 302. After the activated carbon piece on the activated carbon filter assembly 3 that is slidably connected to the box body 1 adsorbs more harmful substances and some impurities, its weight becomes heavier, causing it to slide vertically downward in the movable through-hole 302, so as to judge whether the activated carbon piece is saturated with adsorption, and the activated carbon piece can be flexibly replaced according to different adsorption degrees to improve resource utilization efficiency.

[0023] like Figure 1 - Figure 6As shown, the interior of the box body 1 is divided into multiple cavities, the slide rail 5 is fixedly connected to the box body 1 and extends to the box door 101, and a plurality of perforations are provided on the box body 1 for the ultraviolet lamp 4 to extend into the box body 1 to form an ultraviolet lamp 4 assembly. The activated carbon filter assembly 3 is located on both sides of the ultraviolet lamp 4 assembly to adsorb organic waste gas. The activated carbon filter assembly 3 includes a plate body 301 and a plurality of activated carbon pieces. The plate body 301 is provided with a plurality of movable perforations 302, and the movable perforations 302 are arranged in a matrix array on the plate body 301. The activated carbon piece includes an activated carbon block 305, a support sleeve 308 and a folding baffle 307. The activated carbon piece is located in the movable through-hole 302. The top and bottom surfaces of the support sleeve 308 are fixedly connected to a spring 1 303 and a spring 2 304 respectively. The other end of the spring 1 303 is fixedly connected to the inner top surface of the movable through-hole 302, and the other end of the spring 2 304 is fixedly connected to the inner bottom surface of the movable through-hole 302. The spring 1 303 and the spring 2 304 are used to make the support sleeve 308 slideably connected to the movable through-hole In the hole 302, folding baffles 307 are provided on both the front and rear surfaces of the support sleeve 308. A plurality of connecting strips 309 are fixedly connected to the surface of the support sleeve 308. The connecting strips 309 extend toward the folding baffles 307 and are fixedly connected to the folding baffles 307. The fixed connection method can be glued. The folding baffles 307 are provided in four pieces, which are respectively provided on the two openings of the movable through-hole 302. The top of the folding baffle 307 on the upper half of the movable through-hole 302 is connected to the top of the movable through-hole 302. The bottom of the folding baffle 307 in the lower half of the movable through-hole 302 is fixedly connected to the bottom surface of the movable through-hole 302. When the support sleeve 308 slides, the folding baffle 307 is folded or stretched to ensure the sealing of the movable through-hole 302 and improve the adsorption effect of the activated carbon block 305. The setting of the folding baffle 307 can ensure that the exhaust gas can pass through the activated carbon piece better, rather than directly through the movable through-hole 302 to the other side of the plate body 301, thereby improving the overall filtering effect of the plate body 301.

[0024] like Figure 1 - Figure 6As shown, the activated carbon block 305 is set in a long strip shape, and the activated carbon includes an outer shell and a plurality of activated carbon particles. The outer shell can be a cylindrical structure with a plurality of small through holes. The activated carbon particles are located inside the outer shell, and one end of the outer shell is fixedly connected to a clamping block 306, and the end with the clamping block 306 faces the air inlet 2 of the box body 1. When the activated carbon block 305 is inserted into the supporting sleeve 308, the clamping block 306 is abutted against the outer peripheral wall of the plate body 301. The clamping block 306 is used to improve the structural stability of the activated carbon block 305 on the plate body 301, and it is not easily blown away by the air flow. In addition, the plate body 301 is provided with a plurality of The dry scale line 312, when the activated carbon block 305 is not adsorbed and inserted into the supporting sleeve 308, the clamping block 306 on the activated carbon block 305 is located on the scale line 312. Preferably, the scale line 312 can be flexibly engraved on the plate body 301 according to the different tensions of the spring 1 303. The activated carbon block 305 becomes heavier after absorbing harmful substances, and the activated carbon piece sinks and slides in the movable through-hole 302. The saturation degree of the activated carbon block 305 is judged according to the position of the scale line 312 and the clamping block 306, and the detachable activated carbon block 305 is more convenient and quick to maintain.

[0025] like Figure 1 - Figure 6 As shown, the bottom of the plate body 301 is rotatably connected to a plurality of sliding wheels 310, and the sliding direction of the sliding wheels 310 is the length direction of the slide rail 5. The sliding wheels 310 slide on the slide rail 5, and the sliding wheels 310 make the plate body 301 slide more smoothly on the slide rail 5, and a plurality of limit strips 501 are fixedly connected to the inner wall of the slide rail 5, and a plurality of sliding blocks 311 are fixedly connected to the end surface of the plate body 301 close to the inside of the slide rail 5. When the plate body 301 is slidably connected to the slide rail 5, the sliding block 311 is inserted between two adjacent limit strips 501, thereby improving the stability and structural strength of the plate body 301 on the slide rail 5.

[0026] Working principle: When using this exhaust gas purification photocatalytic device to treat exhaust gas, due to the different wind forces of the exhaust gas brought out by the air inlet 2, the saturation degree of the activated carbon parts on the activated carbon filter assembly 3 is different. The activated carbon parts are detachably connected to the movable perforation 302, and the position of the activated carbon parts on the movable perforation 302 is judged to determine the saturation degree of the activated carbon parts. The plate body 301 is taken out through the sliding wheel 310 at the bottom of the plate body 301 and the position of the snap-in block 306 and the scale line 312 is used to determine whether the activated carbon parts need to be replaced, thereby improving the efficiency of exhaust gas purification and improving the utilization efficiency of the activated carbon parts.
