[0022] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Combine the following Figures 1 to 3 The utility model is described in detail.

[0024] A waste gas purification device of a heating formaldehyde removal equipment includes a main body 1, an exhaust pipe 101 is arranged on one side of the main body 1, an activated carbon plate 2 is connected to the inside of the main body 1, an intake pipe 3 is arranged on the side of the main body 1 away from the exhaust pipe 101, a mounting base 102 is arranged at the bottom of the main body 1, the bottom of the activated carbon plate 2 is connected to the mounting base 102, a cooling component is arranged on the outer wall of the intake pipe 3, the cooling component is penetrated by the intake pipe 3, and the cooling component is partially connected to the intake pipe 3.

[0025] First, the waste gas after formaldehyde removal by heating is transported into the main body 1 through the air inlet pipe 3 , and then the waste gas containing formaldehyde is purified by the activated carbon plate 2 in the main body 1 , and then discharged through the exhaust pipe 101 .

[0026] Furthermore, the mounting base 102 includes a slide groove 103 , which is arranged on the top of the mounting base 102 , and the activated carbon board 2 includes a slider 201 , which is arranged on both sides of the bottom of the activated carbon board 2 , and the slider 201 cooperates with the slide groove 103 .

[0027] At the same time, the activated carbon plate 2 is slidably connected to the mounting base 102 through a slider 201 at the bottom, and one side of the activated carbon plate 2 protrudes from the outer wall of the main body 1, so that the activated carbon plate 2 can be moved along the slide groove 103 on the mounting base 102 by applying force to the part protruding from the outer wall, thereby separating the activated carbon plate 2 from the main body 1 and removing it for easy cleaning.

[0028] Furthermore, the cooling component includes a water flow pipe 4, a branch pipe 301, an atomizing disk 302 and a collecting tank 303. The water flow pipe 4 is arranged on the side wall of the air inlet pipe 3, the branch pipe 301 is arranged on the top of the air inlet pipe 3, the atomizing disk 302 is arranged in the middle of one end of the branch pipe 3, the collecting tank 303 is arranged at the bottom near one end of the air inlet pipe 3, and a water injection pipe is arranged at the end of the water flow pipe 4 near the air inlet pipe 3. The end of the water flow pipe 4 away from the water injection pipe is connected to the outer wall of the main body 1, and the end of the air inlet pipe 3 away from the air inlet end extends through the bottom of the water flow pipe 4. The branch pipe 301 is an inclined cylinder, and the upward inclined part of the branch pipe 301 is connected to the inside of the water flow pipe 4. The atomizing disk 302 is arranged at one end of the branch pipe 301 that extends downwardly to the inside of the air inlet pipe 3.

[0029] When the exhaust gas enters the intake pipe 3, the water flow pipe 4 is connected to the external water injection pipe to inject water into the gap between the water flow pipe 4 and the side wall of the intake pipe 3, so that the water will flow along the gap, thereby reducing the temperature of the intake pipe 3 to cool the exhaust gas after heating and formaldehyde removal. At the same time, when the water flows, the water flows into the part of the branch pipe 301 protruding in the gap, and then because of the continuous water injection pressure, the water is forced to be squeezed and sprayed out from the atomizing disk 302, thereby forming water mist to humidify the exhaust gas, so that harmful particles in the exhaust gas can adhere to the activated carbon plate, and then the water flows out through the water flow pipe 4 connected to one end extending to the outside for recycling.

[0030] Furthermore, the collecting tank 303 also includes a pressure plate 3031 and a flow hole 3032. The pressure plate 3031 is arranged in the middle of the collecting tank 303, and the flow hole 3032 is arranged in the middle of the collecting tank 303 near the bottom end. The bottom of the pressure plate 3031 is connected to the bottom of the collecting tank 303 through a spring telescopic rod.

[0031] At the same time, when water mist is generated to increase humidity, part of the water mist will form water droplets and flow in the intake pipe 3. When it flows to the end of the intake pipe where it is about to be discharged, the water droplets will enter the collecting tank 303, so that the water droplets will gather in the collecting tank 303. When a certain amount is gathered, the formed water flow will be at one end of the intake pipe 3, thereby increasing the humidity of the exhaust gas when it is discharged. At the same time, if too much water accumulates, the weight of the water flow will exert pressure on the pressure plate 3031, forcing the pressure plate 3031 to move downward through the spring telescopic rod at the bottom. When moving downward, the accumulated water flow will contact the flow hole 3032, allowing the water flow to flow out of the flow hole 3032, and at the same time reducing the water flow, so that the pressure plate 3031 will reset, allowing the accumulated water flow to approach the intake pipe 3 again, thereby increasing the humidity of the exhaust gas passing through.

[0032] The following is a specific implementation process of the utility model. First, the exhaust gas after heating and formaldehyde removal is transported into the main body 1 through the intake pipe 3, and then the exhaust gas containing formaldehyde is purified by the activated carbon plate 2 in the main body 1, and then discharged through the exhaust pipe 101. At the same time, the activated carbon plate 2 is slidably connected to the mounting base 102 through the slider 201 at the bottom, and one side of the activated carbon plate 2 protrudes from the outer wall of the main body 1, so that the activated carbon plate 2 can be moved along the slide groove 103 on the mounting base 102 by applying force to the part protruding from the outer wall, so that the activated carbon plate 2 can be separated and taken out from the main body 1 for easy cleaning. When the air pipe 3 is connected, the external water injection pipe is connected through the water flow pipe 4, and water is injected into the gap between the water flow pipe 4 and the side wall of the air inlet pipe 3, so that the water will flow along the gap, thereby reducing the temperature of the air inlet pipe 3 to cool the exhaust gas after heating and formaldehyde removal. At the same time, when the water flows, the water flows into the part of the branch pipe 301 protruding into the gap, and then because of the continuous water injection pressure, the water is forced to be squeezed and sprayed out from the atomizing disk 302, thereby forming water mist to humidify the exhaust gas, so that the harmful particles in the exhaust gas can adhere to the activated carbon plate, and then the water flows out through the water flow pipe 4 connected to one end extending to the outside for recycling.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
