Specific embodiments

[0025] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited are not intended to limit the present utility model.

[0026] Referring to Figures 1 to 6 As shown, a VOC energy-saving exhaust device of the present utility model includes a VOC purification device 11 and a support frame 12 fixedly installed on the outer surface of the top of the VOC purification device 11, a limit rod 13 movably sleeved on the outer surface of the VOC purification device 11, a water vapor filtration box 121 fixedly connected to the top surface of the support frame 12, a return air pipe 122 fixedly connected to one side surface of the water vapor filtration box 121 and arranged on the outer surface of the top of the VOC purification device 11, a diversion air pipe 123 fixedly connected to the other side surface of the water vapor filtration box 121 and arranged on the outer surface of the filtration box 111, a filter sponge plate 126 arranged on the inner wall surface of the water vapor filtration box 121, a filtration box 111 fixedly connected to the top surface of the VOC purification device 11 and located at one side edge position, and a VOC filter plate 114 movably sleeved on the inner wall surface of the filtration box 111.

[0027] During operation, the exhaust fan is used to absorb the VOC gas on the inner wall of the top of the VOC purification device 11, and the VOC gas is injected into the return air pipe 122. At the same time, the return air pipe 122 is used to perform secondary absorption on the VOC gas in the middle and tail parts of the VOC purification device 11, and these semi-treated VOC gases are re-injected into the water vapor filter box 121. At the same time, the filter sponge plate 126 on the inner wall of the water vapor filter box 121 is used to filter the residual chemical agents in the VOC gas, and then the VOC gas is re-injected into the interior of the VOC purification device 11 through the guide air pipe 123, and the guide air pipe 123 is used to inject it into the filter box The airflow inside 111 blows up the gas impurities initially filtered out from the top surface of the VOC filter plate 114, thereby achieving the effect of using the gas refluxed from the side to blow up the VOC impurity gas adhering to the top of the VOC filter plate 114, reducing the VOC impurities on the top surface of the VOC filter plate 114 from clogging the VOC filter plate 114, and avoiding a large amount of VOC gas impurities passing through the VOC filter plate 114. The impurities inside the VOC gas will adhere to the top surface of the VOC filter plate 114, and then block the gap holes on the top surface of the VOC filter plate 114, making it impossible for subsequent VOC gas to effectively pass through the inside of the VOC filter plate 114.

[0028] Further, such as Figures 1 to 6 As shown, elastic wires 124 are fixedly connected to the inner wall surfaces on both sides of the water vapor filter box 121, and a limiting sleeve 125 is fixedly connected to one end of the elastic wire 124. The inner wall surface of the limiting sleeve 125 is detachably mounted on the outer surface of the filter sponge plate 126, and the outer surface of the limiting sleeve 125 is movably sleeved on the inner wall surface of the water vapor filter box 121. An exhaust fan is provided at the connection between the return air pipe 122 and the VOC purification device 11, an air inlet pipe 112 is provided on the top surface of the filter box 111, and an exhaust pipe 113 is fixedly connected to the top surface of the VOC purification device 11 and located at a side edge position, and the limiting rod 13 There are multiple groups of limit rods 13, one end of which is detachably mounted with a motor 131 on the outer surface, and multiple groups of limit rods 13 are movably sleeved with a transmission crawler 132 on the outer surfaces. One end of the limit rod 13 is fixedly connected to a limit turntable 133 located on the inner wall of the VOC purification device 11, and a sealing soft plate 134 movably sleeved on the inner wall of the VOC purification device 11 is provided on the outer surface of the limit turntable 133. An arc plate 135 is fixedly connected to the other side surface of the limit turntable 133, and the interior of the VOC purification device 11 is filled with an ozone chemical covering the outer surface of the arc plate 135.

[0029] During operation, the VOC gas is fed into the interior of the filtration tank 111 in cooperation with the intake pipe 112. Some solid impurities inside the VOC gas are filtered out by the VOC filter plate 114, enabling the VOC gas to enter the interior of the VOC purification device 11. The chemical agent inside the VOC purification device 11 is mixed with the filtered VOC gas. Meanwhile, the motor 131 rotates the limiting rod 13 and drives the transmission track 132 on the outer surface of the limiting rod 13 to rotate multiple limiting rods 13 simultaneously, thereby driving the limiting turntable 133 at one end of the limiting rod 13 to rotate on the inner wall surface of the VOC purification device 11. When the limiting turntable 133 rotates, it drives the arc plate 135 on the outer surface of the limiting turntable 133 to stir and turn inside the VOC purification device 11, achieving the effect of continuously stirring the chemical agent inside the VOC purification device 11 using the curvature of the surface of the arc plate 135 to fully mix the chemical agent with the VOC gas. Then, the VOC gas in the middle and end parts inside the VOC purification device 11 is secondarily absorbed through the reflux gas pipe 122, and these semi-treated VOC gases are re-fed into the interior of the water vapor filtration tank 121 for secondary recycling and utilization.

[0030] Working principle: The VOC gas is fed into the interior of the filtration tank 111 in cooperation with the intake pipe 112. Some solid impurities inside the VOC gas are filtered out by the VOC filter plate 114, enabling the VOC gas to enter the interior of the VOC purification device 11. The chemical agent inside the VOC purification device 11 is mixed with the filtered VOC gas. Meanwhile, the motor 131 rotates the limiting rod 13 and drives the transmission track 132 on the outer surface of the limiting rod 13 to rotate multiple limiting rods 13 simultaneously, thereby driving the limiting turntable 133 at one end of the limiting rod 13 to rotate on the inner wall surface of the VOC purification device 11. When the limiting turntable 133 rotates, it drives the arc plate 135 on the outer surface of the limiting turntable 133 to stir and turn inside the VOC purification device 11, achieving the effect of continuously stirring the chemical agent inside the VOC purification device 11 using the curvature of the surface of the arc plate 135 to fully mix the chemical agent with the VOC gas;

[0031] The exhaust fan is used to absorb the VOC gas on the inner wall of the top of the VOC purification device 11, and the VOC gas is injected into the interior of the return air pipe 122. At the same time, the return air pipe 122 is used to perform secondary absorption on the VOC gas in the middle and tail parts of the VOC purification device 11, and these semi-treated VOC gases are re-injected into the interior of the water vapor filter box 121. At the same time, the filter sponge plate 126 on the inner wall of the water vapor filter box 121 is used to filter out the residual chemical agents in the VOC gas, and then the VOC gas is re-injected into the interior of the VOC purification device 11 through the guide air pipe 123. The airflow injected into the filter box 111 by the guide air pipe 123 is used to blow up the gas impurities filtered out at the beginning on the top surface of the VOC filter plate 114, so as to achieve the effect of using the side reflux gas to blow up the VOC impurity gas adhering to the top of the VOC filter plate 114, thereby reducing the VOC impurities on the top surface of the VOC filter plate 114 that will block the VOC filter plate 114.

[0032] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
