[0029] A calcining furnace tail gas treatment device comprises a furnace body 1 and a treatment box 2, wherein an air guide pipe 101 is fixedly installed at the gas outlet end of the furnace body 1, a treatment chamber 201 is provided inside the treatment box 2, a filter screen plate 2011 is fixedly installed inside the treatment chamber 201, a purification box 202 is fixedly installed on the top of the treatment box 2, an air guide cover 203 is fixedly provided on the top of the purification box 202, a fan 2031 is provided inside the air guide cover 203, a plate groove 204 is provided on the right side surface of the purification box 202, a purification plate 205 is sealed inside the plate groove 204, an activated carbon filter screen 2051 is embedded and installed on the top surface of the purification plate 205, and an installation mechanism 3 is provided between the purification plate 205 and the purification box 202;

[0030] Specifically, the bottom end of the air guide tube 101 is sealed and penetrates the top surface of the processing box 2 and extends to the inner bottom end of the processing chamber 201;

[0031] In this embodiment, the air guide pipe 101 is mainly provided to guide the exhaust gas generated inside the furnace body 1 to the inside of the processing chamber 201, thereby facilitating the subsequent processing of the exhaust gas.

[0032] Specifically, the interior of the processing chamber 201 contains the processing alkali solution, the vertical cross-section of the filter screen plate 2011 is an L-shaped structure, the inner cavity of the purification box 202 is a hollow cylinder with upper and lower openings, and is respectively connected to the interior of the processing box 2 and the air guide cover 203, and the activated carbon filter screen 2051 completely covers the inner cavity of the purification box 202;

[0033] In this embodiment, the alkali solution treatment device is mainly used to contact with the exhaust gas and perform initial adsorption on it, while the filter plate 2011 can perform secondary treatment on the exhaust gas, and the activated carbon filter 2051 purifies the exhaust gas again, thereby improving the treatment effect of the device.

[0034] Specifically, a groove is provided on the right surface of the purification plate 205;

[0035] In this embodiment, the pull groove is provided mainly to facilitate the pulling and drawing operation of the purification plate 205 .

[0036] In this embodiment, please refer to Figure 1 , Figure 4 and Figure 5 The mounting mechanism 3 includes a rotating screw 301 and a locking hole 302. The rotating screw 301 is movably arranged on the front and rear surfaces of the purification box 202 through a bearing, and a movable support plate 303 is sleeved on the outer side thereof. The opposite side surfaces of the movable support plate 303 are fixedly mounted with locking columns 304. A rotating handle 305 is fixedly mounted on one end of the rotating screw 301 away from the purification box 202, and the locking holes 302 are respectively opened on the front and rear surfaces of the purification plate 205;

[0037] Specifically, the rotating screw 301 is distributed in a front-to-back mirror image with respect to the inner central axis of the purification plate 205, and its outer surface is threadedly connected with the inner wall of the movable support plate 303, and the front end of the locking column 304 fits through the rear surface of the purification plate 205 and extends to the inside of the plate groove 204, and is engaged with the locking hole 302;

[0038] In this embodiment, the handle 305 is mainly used to drive the rotating screw 301. When the rotating screw 301 cooperates with the thread of the movable support plate 303, the movable support plate 303 is displaced, so that the locking column 304 and the locking hole 302 are brought close to or away from each other, thereby achieving the purpose of convenient disassembly and assembly of the purification plate 205 and meeting the use needs of the staff.

[0039] The working process of the utility model is as follows: when a calcining furnace tail gas treatment device is used, the tail gas generated in the furnace body 1 enters the treatment chamber 201 through the air guide pipe 101, and then the tail gas contacts the treatment alkali solution in the treatment chamber 201, and then the tail gas is initially treated, and then the tail gas is separated from the treatment alkali solution and contacts the filter plate 2011, thereby completing the secondary treatment of the tail gas, and the tail gas after the secondary treatment contacts the activated carbon filter 2051, thus achieving the re-purification of the tail gas, and the purified gas is discharged through the air guide hood 203 under the action of the fan 2031, and the tail gas is discharged through the air guide hood 203, and the tail gas is discharged. The exhaust gas treatment effect of the device is improved. When the purification plate 205 and the activated carbon filter 2051 need to be replaced, an external force is applied to the rotary handle 305, and the rotary handle 305 drives the rotating screw 301 and the movable support plate 303 to perform displacement transmission, so that the movable support plate 303 drives the locking column 304 to gradually move away from the treatment box 2. When the locking column 304 is completely disengaged from the locking hole 302, the purification plate 205 can be pulled through the pulling groove, thereby realizing the disassembly operation of the purification plate 205, and vice versa, it can complete its installation. This provides convenience for the disassembly personnel and facilitates subsequent use.
