DETAILED DESCRIPTION
[0042] The present invention will be further described in detail below through examples. The examples are only used to illustrate the present invention and do not limit the scope of the present invention.
[0043] A spray gas purification device, comprising:
[0044] The lower filter box 100 is a hollow structure, which is wide at the top and narrow at the bottom. The spraying gas (including impurities generated by the spraying) enters the lower filter box 100 from the bottom, and then moves upward through the lower filter box 100.
[0045] The activated carbon frame 200 is detachably connected to the lower filter box 100. There are two activated carbon frames 200 and they are symmetrically arranged in the lower filter box 100. The activated carbon frames 200 are filled with honeycomb activated carbon (not shown in the figure). The honeycomb activated carbon (not shown in the figure) is in a block shape. There are several honeycomb activated carbon (not shown in the figure) and they are neatly stacked in the activated carbon frames 200. The spray gas entering the lower filter box 100 enters the activated carbon frame 200 from both sides and is then filtered by the honeycomb activated carbon (blocks) in the activated carbon frame 200 before moving upward. The spray gas entering the lower filter box 100 moves from both sides to the upper middle position of the lower filter box 100 and continues to move upward into the upper filter box 300 (discussed later).
[0046] The upper filter box 300 is connected to the upper part of the lower filter box 100. The upper filter box 300 is arranged horizontally. The spray gas entering the upper filter box 300 moves toward the two sides of the upper filter box 300, and then moves upward from the two side outlets of the upper filter box 300. Of course, honeycomb activated carbon (not shown in the figure) can be placed in the upper filter box 300. The honeycomb activated carbon (not shown in the figure) is in a block shape, which further filters the spray gas.
[0047] The exhaust box 400 is connected to the upper filter box 300, and the exhaust box 400 is sealed and fastened to the upper part of the upper filter box 300; the lower filter box 100, the activated carbon frame 200, the upper filter box 300 and the exhaust box 400 cooperate to make the spray gas present an "S"-shaped movement trajectory, which is conducive to further purification of the spray gas before being discharged to the outside. The spray gas generated by spraying (including impurities generated by spraying) passes through the lower filter box 100 and then enters the activated carbon frame 200 from both sides thereof, and is filtered by the honeycomb activated carbon (blocks) in the activated carbon frame 200. The filtered spray gas enters the upper filter box 300 from bottom to top, and then enters the exhaust box 400 through an "S"-shaped movement trajectory, and is finally discharged to the outside through the exhaust box 400. In this way, on the one hand, the spray gas is filtered by the honeycomb activated carbon (not shown in the figure) in the activated carbon frame 200, and on the other hand, the "S"-shaped design of the spray gas path increases the movement of the spray gas, which is more conducive to the precipitation and filtration of the spray gas.
[0048] The lower filter box 100 includes:
[0049] The conical bucket 110 is a bucket-shaped structure with an inlet at its lower portion. External spray gas enters the conical bucket 110 through the inlet and then moves upward.
[0050] The box body 120 has an open lower portion, and a transverse baffle 1201 is fixed in the middle of its lower portion. The transverse baffle 1201 is a rectangular plate structure. When the activated carbon frame 200 is located in the lower filter box 100, the lower end surface of the activated carbon frame 200 is flush with the lower end surface of the transverse baffle 1201, and at the same time, the projection of the transverse baffle 1201 toward the channel box 130 covers the channel box 130; in this way, when the activated carbon frame 200 is later inserted into the lower filter box 100, the gas can enter the activated carbon frame 200 laterally from both sides of the lower filter box 100 and then enter the channel box 130.
[0051] An outlet window 121 is formed through the upper portion of the box body 120. The outlet window 121 is a rectangular structure (note that it is a whole rectangle to distinguish it from the socket discussed later). The activated carbon frame 200 matches the outlet window 121 and can pass through the outlet window 121.
[0052] The channel box 130 is connected to the middle position of the upper part of the box body 120. The channel box 130 is a rectangular hollow structure with open sides. Its bottom is vertically fixed to the upper part of the box body 120. Specifically, the bottom of the channel box 130 is fixed to the middle position of the outlet window 121. A socket 141 and a socket 2 142 are formed between the channel box 130 and the outlet window 121. The socket 1 141 and the socket 2 142 are matched with each other; the bottom of the channel box 130 divides the outlet window 121 into a socket 141 and a socket 2 142. The activated carbon frame 200 is respectively connected to the socket 141 and the socket 2 142. After installation, the activated carbon frame 200 is located at the lower parts of both sides of the channel box 130. The activated carbon frame 200 constitutes a part of the movement path of the spray gas. Later, the spray gas enters the activated carbon frame 200 from both sides of the lower filter box 100 and converges to the middle position inside the box body 120 and then moves upward into the channel box 130.
[0053] The activated carbon frame 200 includes:
[0054] The carbon frame 1 210 is a rectangular frame structure with two openings on both sides. The carbon frame 1 210 is matched and inserted into the socket 1 141 .
[0055] Carbon frame 2 220 is a rectangular frame structure with open sides. Carbon frame 220 is matched and inserted into socket 2 142. Carbon frame 1 210 and carbon frame 2 220 have the same structure. After being placed, the open sides of carbon frame 1 210 and carbon frame 2 220 face the channel box 130, and the lower end faces of carbon frame 1 210 and carbon frame 2 220 are flush with the lower end face of the cross baffle 1201. When carbon frame 1 210 and carbon frame 2 220 are placed in the lower filter box 100, the bottom of carbon frame 1 210 and carbon frame 2 220 together with the cross baffle 1201 "block" the gas in the lower filter box 100 from moving directly vertically upward, so that the gas moves toward both sides of the cross baffle 1201 and enters the honeycomb activated carbon (not shown in the figure) in the activated carbon frame 200 from the side.
[0056] Preferably, elastic strips 211 are fixed on both sides of the carbon frame 1 210. The elastic strips 211 are made of rubber material and are elastic. Gaps 212 are set between adjacent elastic strips 211. The elastic strips 211 are also fixed on the carbon frame 220 and will not be repeated here. When placing honeycomb activated carbon (not shown in the figure) into the activated carbon frame 200, the elastic strips 211 can be moved to increase the spacing of the gaps 212, thereby facilitating the placement of the honeycomb activated carbon (not shown in the figure) into the activated carbon frame 200. Then, the elastic strips 211 are released to reset the gaps 212 to prevent the honeycomb activated carbon (not shown in the figure) from separating from the activated carbon frame 200.
[0057] Preferably, a hanging plate 213 is fixed on the carbon frame 1 210. The cross section of the hanging plate 213 is in the shape of a "" and the upper end of the hanging plate 213 protrudes from the outer edge of the carbon frame 1 210. The hanging plate 213 is also fixed on the carbon frame 220 and will not be described in detail.
[0058] The lower part of the channel box 130 is provided with fixed flanges 1301 on both sides, and the flanges 1301 protrude outward from the outer surface of the channel box 130; when the carbon frame 210 is inserted into the lower filter box 100, the hanging plate 213 contacts the upper surface of the flange 1301, and the position of the carbon frame 210 relative to the channel box 130 and the lower filter box 100 is stable.
[0059] Preferably, a hole 131 is formed through one side of the channel box 130. The hole 131 is rectangular, and the drawer 132 passes through the hole 131. The main body of the drawer 132 is a rectangular plate structure, and a baffle 1321 is fixed around it. The baffle 1321 surrounds the drawer 132. The drawer 132 is provided with a plurality of through holes 1322 that are evenly distributed.
[0060] Preferably, a layer of activated carbon particles may be laid on the drawer 132 to further filter the spray gas entering the channel box 130 from the box body 120 .

[0063] Sealing covers 330 are provided on both sides of the upper filter box 300; the sealing covers 330 are used to seal the openings on both sides of the upper filter box 300, and the sealing covers 330 are detachable relative to the upper filter box 300. This makes it easier to clean the interior of the upper filter box 300 later, and on the other hand, when necessary, the sealing covers can be opened to place filter materials such as honeycomb activated carbon (not shown) in the upper filter box 300 to further filter the gas.
[0064] The cover 330 includes:
[0065] The cover plate 331 is a rectangular structure;
