Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5As shown, a building fire smoke purification device includes a base plate 1, with casters 101 at the four corners of the bottom of the base plate 1. A push handle 102 is fixedly connected to one side of the base plate 1, and a purification box 2 is bolted to the top of the base plate 1. The purification box 2 stores a solution, which is water or quicklime water, preferably quicklime water. Quicklime water is a calcium hydroxide solution produced by the reaction of quicklime and water. Carbon dioxide, formic acid, acetic acid, dust particles and impurities in the smoke, as well as sulfides therein, can be absorbed. A liquid addition pipe 201 is fixedly connected to the top of the purification box 2, and a sealing plug 202 made of rubber is provided at the port of the liquid addition pipe 201. A drain pipe 203 is fixedly connected to one side of the bottom of the purification box 2, and a solenoid valve is provided in the drain pipe 203. A transparent window 7 is provided on the front of the purification box 2. When the sealing plug 202 is opened and new solution is added to the purification box 2 through the liquid addition pipe 201, the amount of solution in the purification box 2 can be easily observed through the transparent window 7.

[0027] The purification chamber 2 is equipped with a suction assembly for drawing flue gas into the solution. The suction assembly includes an exhaust fan 302 fixedly connected to the top of the purification chamber 2. The exhaust fan 302 is a fire exhaust axial flow fan. An air inlet pipe 303 is fixedly connected to the air inlet of the exhaust fan 302. An air collection hood 304 is fixedly connected to the other end of the air inlet pipe 303. The section of the air inlet pipe 303 near the exhaust fan 302 is a corrugated pipe, and the rest is a rigid pipe. An air outlet pipe 305 is fixedly connected to the air outlet of the exhaust fan 302. The air outlet pipe 305 extends into the solution stored in the purification chamber 2. A gas distribution plate 306 is fixedly connected to the bottom of the air outlet pipe 305. Several air outlet holes are opened at the bottom of the gas distribution plate 306. An installation hole is opened on the rear side of the purification chamber 2. An exhaust fan 301 is fixedly connected in the installation hole.

[0028] Multiple sets of baffles 401 located above the gas distribution plate 306 are fixedly connected between the inner walls of the purification box 2. A needle 402 is fixedly connected to the bottom of the baffle 401. The multiple sets of baffles 401 are located in the solution and at different heights. The multiple sets of baffles 401 are staggered. The air outlet pipe 305 passes through the middle of the baffles 401.

[0029] The top of the purification box 2 is equipped with a lifting assembly, which includes a hydraulic cylinder 601 fixedly connected to the top of the purification box 2. A support plate 602 is fixedly connected to the top of the hydraulic cylinder 601. The rigid part of the air inlet pipe 303 near the air collection hood 304 is fixedly connected inside the support plate 602. The height of the support plate 602 is adjusted by the hydraulic cylinder 601, thereby adjusting the height of the air collection hood 304. Since most of the flue gas is dispersed at high altitudes, raising the height of the air collection hood 304 can improve the efficiency of flue gas purification.

[0030] The purification chamber 2 is equipped with an agitation mechanism, which includes a rotary motor 501. The output end of the rotary motor 501 is connected to a rotary shaft 502 via a coupling. Several soft bristles 503 are fixedly connected to the rotary shaft 502. The rotary shaft 502 is located below the gas distribution plate 306. When the rotary motor 501 is started, the rotary motor 501 drives the rotary shaft 502 to rotate the soft bristles 503. This not only breaks the air bubbles and makes the flue gas and the solution in the purification chamber 2 mix thoroughly, but also agitates the solution to prevent the particles in the flue gas from settling and being difficult to discharge with the solution.

[0031] The agitation mechanism also includes a power assembly, which drives the rotary motor 501 to move the rotary shaft 502 back and forth inside the purification chamber 2. The power assembly includes a drive motor 504 bolted to one side of the purification chamber 2. The output end of the drive motor 504 is connected to a lead screw 505 via a coupling. The lead screw 505 is rotatably connected between the inner walls of the purification chamber 2. A slider 506 is threaded onto the lead screw 505. The slider 506 slides along the inner wall of the purification chamber 2. The rotary motor 501 is bolted to the slider 506.

[0032] Working Principle: When a fire occurs inside the building, the base plate 1 is moved to a suitable fire area by the cooperation of the push handle 102 and the casters 101. The induced draft fan 302 is started, and the smoke is drawn into the purification box 2 through the air collection hood 304 and the air inlet pipe 303. Then, the smoke enters the gas distribution plate 306 through the air outlet pipe 305. The gas distribution plate 306 disperses the smoke into the solution stored inside the purification box 2. The solution absorbs carbon dioxide, formic acid, acetic acid, dust particles, etc. in the smoke. The gas discharged from the gas distribution plate 306 gradually moves upward. After being blocked by the baffle plate 401, part of it moves downward. The needles 402 on the baffle plate 401 puncture the air bubbles, allowing the smoke to escape. The gas and solution are thoroughly mixed. The purified flue gas is promptly discharged from the purification chamber 2 by the exhaust fan 301. At the same time, the rotary motor 501 and the drive motor 504 are started. The rotary motor 501 drives the rotary shaft 502 to rotate the soft bristles 503. The drive motor 504 drives the lead screw 505 to rotate. The lead screw 505 drives the slider 506 to move the rotary motor 501 and the rotary shaft 502 back and forth in the purification chamber 2. As the soft bristles 503 rotate, they help to break the air bubbles discharged from the bottom of the gas distribution plate 306, allowing them to better contact the solution. At the same time, the rotary shaft 502 and the soft bristles 503 agitate the solution, preventing the particles in the flue gas from settling and facilitating their discharge with the waste solution.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
