[0029] As Figures 1 to 9 shown, an exhaust gas purification and environmental protection device includes a first housing 1, an intake pipe 2 is provided on the first housing 1, a first air pump 21 is provided on the surface of the intake pipe 2, and a water washing component 3 is provided on the bottom surface of the first housing 1. The end of the intake pipe 2 is located inside the water washing component 3 for washing the exhaust gas; As Figure 1 , Figure 2 , Figure 3 and Figure 6 shown, specifically, the water washing component 3 includes bolts 301 provided on the bottom surface of the first housing 1, and a water washing tank 302 is connected to the bottom surface of the first housing 1 through the bolts 301. The end of the intake pipe 2 is located inside the water washing tank 302. Water inlets 303 and a drain outlet 304 are provided on the surface of the water washing tank 302, and valves 305 are provided on the surfaces of the water inlets 303 and the drain outlet 304.
[0030] More specifically, the water inlet 303 is used to inject water into the water washing tank 302, the drain outlet 304 is used to discharge the washed sewage, and the valve 305 on its surface is used to control the on-off of the water flow and adjust the water flow rate, so as to achieve precise control of the water level and water flow state in the water washing tank 302, ensure the normal progress of the water washing process, and effectively remove water-soluble pollutants and dust in the exhaust gas.
[0031] As Figure 2 , Figure 3 and Figure 6 shown, in some practical applications, the water washing tank 302 can be made of a transparent material, and scale lines 306 are provided on the surface of the water washing tank 302 for observing the water level inside the water washing tank 302.
[0032] More specifically, the staff can directly observe the change of the water level in the tank through the transparent water washing tank 302, and the scale lines 306 provide an accurate water level scale reference, which is convenient for the staff to timely and accurately understand the water level height in the water washing tank 302, so as to supplement or replace the water washing liquid in a timely manner according to actual needs, ensure the effect and efficiency of the water washing process, and ensure the stability of the exhaust gas purification quality.
[0033] The end face of the first housing 1 is connected with a plasma purification component 4;
[0034] As Figure 1 , Figure 2 , Figure 3 and Figure 7 shown, specifically, the plasma purification component 4 includes a first channel 401 fixedly installed on the end face of the first cover 1, and a partition 402 is fixedly installed on the inner wall of the first channel 401. A high-voltage electric field generator 403 is installed inside the first channel 401. High-energy electrons are generated by the high-voltage electric field generator 403 to activate the waste gas molecules. A high-voltage electric field controller 404 is arranged on the surface of the first channel 401 for controlling the power and parameters of the high-voltage electric field generator 403.
[0035] More specifically, when the waste gas flows through the first channel 401, the high-voltage electric field generator 403 generates high-energy electrons under the control of the high-voltage electric field controller 404. These high-energy electrons collide with the waste gas molecules to activate the waste gas molecules, causing them to undergo chemical reactions and decompose into harmless or low-harm small-molecule substances. At the same time, a large number of active free radicals are generated, further oxidizing and decomposing the organic matter in the waste gas, thereby achieving efficient purification of the waste gas.
[0036] The end face of the plasma purification component 4 is connected to a photocatalytic oxidation component 5, and the end face of the photocatalytic oxidation component 5 is connected to a second cover 6; as Figure 1 , Figure 2 , Figure 3 and Figure 8 shown, the photocatalytic oxidation component 5 includes a second channel 501 fixedly installed on the end face of the first channel 401. A frame 502 is fixedly installed on the inner wall of the second channel 501. A photocatalyst carrier 503 is arranged on the inner wall of the frame 502. A number of groups of ultraviolet lamps 504 are fixedly installed on both inner walls of the second channel 501, and a metal protective cover 505 is fixedly installed on both inner walls of the second channel 501. The metal protective cover 505 is arranged corresponding to the ultraviolet lamps 504, and a lamp tube controller 506 is fixedly installed on the surface of the second channel 501.
[0037] More specifically, when the waste gas purified by the plasma enters the second channel 501, the ultraviolet lamps 504 emit ultraviolet light with a specific wavelength under the control of the lamp tube controller 506. The photocatalyst on the photocatalyst carrier 503 is excited under the irradiation of the ultraviolet light, generating strongly oxidizing active substances such as hydroxyl free radicals. These active substances undergo deep oxidation reactions with the organic matter and odor gases in the waste gas, converting them into harmless substances such as carbon dioxide and water, further improving the purification degree of the waste gas and making the waste gas meet the emission standards.
[0038] As Figure 1 , Figure 2 , Figure 3 and Figure 8As shown, in some practical applications, the photocatalyst carrier 503 is made of honeycomb ceramics and its surface is coated with a photocatalyst active coating. The coating is attached to the surface of the carrier through special impregnation and coating processes to form a uniform and firm photocatalytic active layer.
[0039] More specifically, the photocatalyst carrier 503 is made of honeycomb ceramics, which has a high specific surface area and good air permeability, can provide a large reaction surface, enhance the adhesion amount and reaction rate of the photocatalyst. Its surface is evenly coated with a photocatalyst active coating through special impregnation and coating processes. The main components of this coating are semiconductor materials such as nano-titanium dioxide (TiO2), which have strong redox properties and good photocatalytic activity. Under the irradiation of ultraviolet light, the photocatalyst active coating can be effectively excited to generate a large number of highly oxidizing active free radicals. These active free radicals react with the organic molecule in the waste gas, oxidize and decompose them into harmless substances such as carbon dioxide and water, thus realizing the deep purification of the waste gas, effectively removing harmful organic substances and odor gases in the waste gas, and improving the waste gas purification effect.
[0040] The second cover 6 is provided with a plug-in through hole, and a detachable activated carbon adsorption component 7 is vertically inserted into the through hole; as Figure 1 、 Figure 2 、 Figure 3 and Figure 9 shown, the detachable activated carbon adsorption component 7 includes a box body 701 vertically inserted into the plug-in slot on the top surface of the second cover 6. Through slots 702 are opened on both side walls of the box body 701, and a stainless steel mesh plate 703 is fixedly installed in the through slots 702. The top of the box body 701 is covered with a sealing cover 704, and a handle 705 is fixedly installed on the top surface of the sealing cover 704. The inside of the box body 701 is filled with activated carbon particles.
[0041] More specifically, the inside of the box body 701 is filled with activated carbon particles. Activated carbon has high adsorption performance and can adsorb a small amount of remaining organic substances and odor molecules in the waste gas. When the waste gas flows through the activated carbon particles in the detachable box body 701, the activated carbon particles adsorb the harmful substances in the waste gas on the surface through physical adsorption, thereby further purifying the waste gas and ensuring that the waste gas is discharged after meeting the emission standards.
[0042] The end face of the second cover 6 is connected with an exhaust pipe 8. A second air extraction pump 81 is arranged on the surface of the exhaust pipe 8. A pre-filtering component 9 is connected to the input end of the intake pipe 2 for filtering dust impurities in the waste gas; as Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown in the figure, specifically, the pre-filtering assembly 9 includes a main pipeline 901 fixedly installed at the input end of the intake pipe 2, and a branch pipe 902 is provided on the main pipeline 901. A limiting ring 903 is fixedly installed on the inner wall of the main pipeline 901, and a filter screen 904 is installed on the main pipeline 901 in a manner that fits the surface of the limiting ring 903. The bottom end of the branch pipe 902 is inserted with a collection box 905.
[0043] More specifically, the filter screen 904 is inclinedly installed in the main pipeline 901. The limiting ring 903 plays a role in limiting and supporting the filter screen 904. The collection box 905 is located below the filter screen 904 for collecting the filtered dust and impurities, realizing the preliminary filtration of the dust in the waste gas, and avoiding large particle impurities from affecting the normal operation and service life of the subsequent purification assembly.
[0044] As Figure 5 shown in the figure, in some practical applications, the filter screen 904 is inclinedly installed in the main pipeline 901 under the limitation of the limiting ring 903, and the filter screen 904 is located above the branch pipe 902.
[0045] More specifically, since the inclined filter screen 904 is located above the branch pipe 902, the dust accumulated on the surface of the collection box 905 can fall into the collection box 905 under the action of gravity.
[0046] In summary: The waste gas enters the device through the intake pipe 2, and is first pretreated by the pre-filtering assembly 9 to realize the preliminary filtration of the dust in the waste gas, avoiding large particle impurities from affecting the normal operation and service life of the subsequent purification assembly. Subsequently, the waste gas enters the water washing assembly 3 to wash the waste gas with water, preliminarily removing some soluble gas pollutants and dust in the waste gas, and at the same time playing a role in cooling and humidifying the waste gas, adjusting the state of the waste gas, which is beneficial to subsequent purification treatment. Then the waste gas passes through the plasma purification assembly 4, the photocatalytic oxidation assembly 5 and the detachable activated carbon adsorption assembly 7 in sequence, and finally is discharged through the exhaust pipe 8 to complete the purification treatment of the waste gas.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
