[0001] The utility model relates to an environmental pollution prevention and control device with a purification structure, in particular to an environmental pollution prevention and control device with a purification structure, belonging to the technical field of environmental pollution prevention and control. Background Art

[0002] Environmental pollution refers to natural or man-made destruction, the act of adding certain substances to the environment that exceed the self-purification capacity of the environment and cause harm. Due to human factors, the composition or state of the environment changes, the environmental quality decreases, thus disrupting and destroying the ecosystem and the normal production and living conditions of human beings.

[0003] The existing technologies for environmental pollution prevention and control have the following disadvantages: 1. When purifying polluted air, activated carbon is often used to adsorb it. During the continuous adsorption process, the activated carbon needs to be manually replaced after it is saturated. If the activated carbon is forgotten to be replaced or is continuously used after saturation, the prevention and control effect will be affected; 2. The exhaust gas is purified by filtering components and activated carbon, and the purification efficiency is low. Therefore, improvements are made to the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an environmental pollution control device with a purification structure in order to solve the above-mentioned problem. When the activated carbon in the control box continues to adsorb the air, after a certain period of time, the activated carbon falls between the partition b and the top plate for desorption. The desorbed activated carbon is transported back between the partition c and the partition frame, and the adsorption effect is good; the cold catalyst filter, the electrostatic electret filter, the biological activated carbon, the ultraviolet lamp, etc. cooperate to achieve a better purification effect.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: an environmental pollution control device with a purification structure, including a control box, the control box is equipped with a filter screen, the filter screen is located above the cold catalyst filter screen, the cold catalyst filter screen is located above the electrostatic electret filter screen, the control box is equipped with a baffle, the baffle is located below the biological activated carbon, the baffle is located above the ultraviolet lamp, the ultraviolet lamp is located behind the photocatalyst, the ultraviolet lamp is located above the partition c, the partition c is located above the activated carbon, the activated carbon is located above the partition frame, the partition frame is connected to the partition b through a feed pipe, the control box is slidably connected to the top plate, and the control box is communicated with the heating box.

[0006] Preferably, an air inlet is provided at the top of the prevention and control box, and an air supply pipe is installed at the outside of the prevention and control box.

[0007] Preferably, a guide frame is installed in the prevention and control box, and the guide frame is located above the fan b.

[0008] Preferably, the fan b is installed on the surface of the partition a, and the air outlet of the fan b extends to the interior of the aeration pipe, and the aeration pipe is located above the baffle.

[0009] Preferably, an air return pipe is installed on the left side of the prevention and control box, and a feed pipe is installed on the left side of the partition frame.

[0010] Preferably, an electric push rod is installed in the prevention and control box, and the electric push rod is installed with a top plate.

[0011] Preferably, a fan a is installed in the heating box, and the fan a is located below the electric heating tube.

[0012] The beneficial effects of the utility model are:

[0013] When the activated carbon in the prevention and control box continuously adsorbs the air, after a certain period of time, the activated carbon falls between the partition b and the top plate for desorption, and the desorbed activated carbon is transported back to between the partition c and the partition frame, with good adsorption effect; the outside air enters the prevention and control box and continuously moves downward, and after being catalytically oxidized by the ultraviolet lamp and the photocatalyst, it enters between the partition c and the partition frame through the air outlet opened on the partition c and contacts with the activated carbon for adsorption. After the activated carbon is adsorbed for a certain period of time, the valve on the discharge pipe on the right side of the bottom end of the partition frame is opened regularly, and the activated carbon on the partition frame continuously falls between the partition b and the top plate through the discharge pipe. After the activated carbon falls, the electric heating pipe in the heating box is energized to generate heat to heat the air, and the heated air is heated in Under the action of fan a, it is transported between partition b and the top plate, which can heat and desorb the activated carbon, so that the gas adsorbed in the activated carbon escapes from the activated carbon, and is transported into the space between the baffle and the partition c through the return air pipe connected on the left. After photolysis treatment by ultraviolet lamp and photocatalyst, the valve on the feeding pipe is opened after the activated carbon is desorbed, and the electric push rod is extended to push the top plate up. The top plate continues to move up to push the activated carbon on the top plate up, and the activated carbon moves up through the feeding pipe back to between the partition c and the partition frame. After entering, the valve on the feeding pipe is closed, and the activated carbon can have a good adsorption effect again. Most of the activated carbon can be desorbed at regular intervals to maintain a good adsorption effect and avoid affecting the purification effect due to long-term non-replacement.

[0014] The cold catalyst filter, electrostatic electret filter, biological activated carbon, ultraviolet lamp, etc. work together to achieve a good purification effect; fan b starts to draw air upward, and the outside air enters the prevention and control box through the air inlet, first contacts the filter to filter the air, and then moves down to pass through the cold catalyst filter. The cold catalyst can catalyze a reaction under normal temperature conditions, and decompose a variety of harmful odorous gases into harmless and odorless substances at normal temperature and pressure, changing from simple physical adsorption to chemical adsorption, while decomposing while adsorbing, removing harmful gases such as formaldehyde, benzene, xylene, toluene, TVOC, and generating water and carbon dioxide. After being treated by the cold catalyst filter, the air moves down to pass through the electrostatic electret filter. The dielectric that stores space charge and dipole charge for a long time in the electrostatic electret filter can filter the air while using the electrostatic force of the charge to capture dust particles, which can be further The air is further dusted. After dust removal, the air is transported into the aeration pipe under the action of the fan b, and is transported upward through the aeration pipe to contact with water. Some organic matter is dissolved in the water and degraded by biological activated carbon. The undissolved air is transported into the space between the baffle and the partition c through the air supply pipe. After the ultraviolet lamp is powered on, it emits ultraviolet rays, which are irradiated on the surface of the photocatalyst coated on the inner wall of the prevention and control box, producing a strong catalytic oxidation effect, which can decompose toxic and harmful gases in the air into water and carbon dioxide, and can effectively kill a variety of bacteria. The treated air is transported downward through the air outlet opened on the partition c and contacts with the activated carbon. The activated carbon has a good adsorption effect and can adsorb the harmful gases that are not completely treated. It can achieve a good purification effect through the cold catalyst filter, electrostatic electret filter, biological activated carbon, ultraviolet lamp, photocatalyst and activated carbon.
