[0015] Preferably, a plurality of air intake fans are arranged inside the fixing block, and a through slot is also provided on one side of the fixing block.

[0016] Beneficial effects of the utility model:

[0017] 1. This organic pollutant waste gas treatment device is provided with a filter assembly. Through the setting of the baffle in the filter assembly, the waste gas is forced to flow forward and enter the filter plate for filtration. The two-way filtration design of the filter plate increases the residence time of the waste gas in the filter plate and increases the contact time with the activated carbon material, thereby improving the filtration efficiency and more effectively purifying the waste gas. The setting of the positioning plate and the rotating grille ensures that the airflow passes through the filter plate smoothly, and can remain smooth even when the filter plate is blocked or contaminated. When the waste gas flow rate is large, the rotating grille will automatically open to ensure the smooth passage of the airflow, thereby ensuring the normal operation of the treatment equipment, and the rotating grille blocks the positioning plate when there is no airflow passing through to prevent backflow or leakage of the waste gas, thereby ensuring the filtering effect of the waste gas and protecting the equipment from the influence of waste gas leakage. At the same time, the guide block in the filter assembly prevents the waste gas from passing directly, and it must pass through the filter plate to enter other parts of the treatment box, which ensures that the waste gas must pass through the filter plate and avoids the possibility of bypassing the filter plate, thereby ensuring the full filtration and purification effect of the waste gas.

[0018] 2. This type of organic pollutant waste gas treatment device is equipped with a collecting component. The inverted trapezoidal design of the reflux groove in the collecting component helps to guide the waste gas to flow downward along the reflux groove, thereby prolonging the residence time of the waste gas at the mouth of the collecting groove. Various solid particles can fall here, and when the airflow is guided in the reflux groove, it will no longer carry out the fixed particles, effectively preventing the solid particles or liquid pollutants in the waste gas from overflowing or splashing again, and directly entering the collection box. The inclined setting of the collection box makes the fixed particles flow toward the mouth of the collection box, which is convenient for collection and centralized treatment.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0029] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

[0030] like Figures 1 to 6 As shown, the organic pollutant waste gas treatment device includes a base 1, a filtering component and a collecting component, and is characterized in that a treatment box 2 is fixedly installed on the top of the base 1, and an air inlet hopper 3 and an air outlet hopper 4 are respectively arranged at both ends of the treatment box 2; the filtering component is fixedly installed on both sides of the inside of the treatment box 2, and the filtering component is used to filter the waste gas; the collecting component is fixedly installed below the base 1, and the collecting component is used to collect waste residues generated during the waste gas filtering, and the collecting component includes a plurality of collecting troughs 13 opened at the bottom end of the base 1, and two collecting boxes 14 located at the bottom end of the base 1, and the collecting troughs 13 are arranged through the base 1 and are connected to the collecting boxes 14; the air inlet hopper 3 and the air outlet hopper 4 are both arranged in a trapezoidal shape, the air inlet hopper 3 and the air outlet hopper 4 are arranged opposite to each other, and the air inlet hopper 3 and the air outlet hopper 4 are both arranged with an opening at one end away from the treatment box 2;

[0031] The waste gas first enters the treatment box 2 through the air inlet hopper 3, and is filtered and treated by the filter component to remove pollutants such as organic pollutants. The filtered waste gas is then discharged through the air outlet hopper 4 and discharged into the environment. The filter component will gradually accumulate waste residues, and the collection component is used to collect these waste residues for subsequent treatment or disposal. The organic pollutant waste gas can be continuously treated and purified, thereby achieving the purpose of reducing air pollution. Therefore, the device only needs to connect the discharge port of the waste gas source to the air inlet hopper 3, and then turn on the equipment to start the waste gas treatment. The filtered waste gas will be discharged from the air outlet hopper 4, and the waste residue will be collected by the collection component. As time goes by, the waste residue in the collection component will increase, requiring regular cleaning and treatment.

[0032] like Figure 2 , Figure 3 , Figure 5 As shown, the filter assembly includes filter plates 5 fixedly mounted on both sides of the base 1, and a plurality of positioning plates 8 arranged on one side of the two filter plates 5, the plurality of positioning plates 8 are installed in an inclined state between the filter plates 5 and the inner wall of the base 1, the filter plates 5 are filled with activated carbon material for filtering and purifying organic pollutant waste gas, the end of the filter plates 5 close to the air inlet hopper 3 is provided with a baffle 6 to block the entry of waste gas, the end of the filter plates 5 close to the air outlet hopper 4 is provided with an air outlet groove 7 for waste gas treatment and discharge, a guide block 11 is fixedly mounted on the end of the treatment box 2 close to the air outlet hopper 4, and the two sides of the guide block 11 are respectively fixedly connected to the two filter plates 5, the side of the guide block 11 close to the air inlet hopper 3 is conically arranged, the air outlet groove 7 is inclined, the two side edges of the air outlet hopper 4 are consistent with the inclination of the two positioning plates 8, and the air outlet groove 7 is formed, and a plurality of rotating grilles 9 are rotatably installed inside the positioning plate 8, and a rotating shaft 10 is arranged between the plurality of rotating grilles 9 and the positioning plate 8 for rotational connection;

[0033] After the exhaust gas enters from the air inlet of the air inlet hopper 3, the exhaust gas will first be blocked by the baffle 6 on the treatment side, causing the exhaust gas to flow forward. When the exhaust gas flows forward, the exhaust gas will be filtered through the filter plates 5 on both sides and enter the other side of the filter plate 5, which can increase the residence time of the exhaust gas inside the filter plate 5, increase the contact time with the activated carbon material, and improve the filtration efficiency. When the airflow enters the other side of the filter plate 5, because the several positioning plates 8 on the other side of the filter plate 5 are inclined, the entry of the airflow will promote the several rotating grilles 9 in the positioning plate 8 to rotate, so that the airflow passes through unimpeded, ensuring the smooth flow of the exhaust gas. When there is no airflow passing through, the rotating grille 9 blocks the positioning plate 8 to prevent backflow or leakage of the exhaust gas, thereby ensuring the filtering effect. The guide block 11 blocks the possibility of direct passage of the exhaust gas inside the treatment box 2, ensuring that the exhaust gas must pass through the filter plate 5 before entering the filter plate 5, avoiding the exhaust gas bypassing the filter plate 5, and ensuring sufficient filtration of the exhaust gas.

[0034] like Figure 4 As shown, the top surface of the base 1 is provided with two reflux grooves 12 corresponding to two collection boxes 14, the reflux groove 12 is arranged in an inverted trapezoidal shape, and the collection groove 13 is arranged in the middle of the bottom of the reflux groove 12, and the collection box 14 is arranged in an inclined shape, with an open mouth and a tightened tail;

[0035] The inverted trapezoidal design of the reflux groove 12 helps to guide the exhaust gas to flow downward along the reflux groove 12, thereby prolonging the residence time of the exhaust gas at the collecting groove 13, and various solid particles can fall here. When the airflow is guided in the reflux groove 12, the fixed particles will no longer be brought out, which effectively prevents the solid particles or liquid pollutants in the exhaust gas from overflowing or splashing again, and directly enters the collecting box 14. The collecting box 14 is set with an open mouth and a tightened tail, and is longitudinally installed under the base 1. One side is narrow in height and the other side is wide in height, which causes the bottom of the collecting box 14 to tilt, so that the fixed particles and the like flow toward the open mouth of the collecting box 14, which is convenient for collection and centralized treatment.

[0036] like Figure 1 , Figure 6 As shown, a plurality of air intake boxes 15 are further provided at the bottom of the treatment box 2, and a plurality of air intake boxes 15 include a water tank 16, a fixing block 17 and a dust screen 20 inside. The water tank 16 is located above the inside of the air intake box 15, and the dust screen 20 is located below the inside of the air intake box 15 and communicates with the inside of the treatment box 2. The fixing block 17 is located between the water tank 16 and the dust screen 20, and a plurality of air intake fans 18 are provided inside the fixing block 17. A through slot 19 is also provided on one side of the fixing block 17.

[0037] A water tank 16 and an air intake fan 18 are provided in the air box. By utilizing the cooling effect of water and the blowing effect of the fan, cold air can be blown into the treatment box 2, thereby effectively reducing the temperature inside the treatment box 2 and helping to improve the efficiency of exhaust gas treatment. In addition, by blowing cold air into the treatment box 2, the cooling of organic matter in the exhaust gas can be promoted, reducing the possibility of its decomposition or combustion, and helping to improve the effect of exhaust gas treatment. When the intake air passes through the water tank 16, the humidity can be increased, which is beneficial to reduce the dust content in the exhaust gas and helps to improve the exhaust gas treatment effect. Moreover, through the through groove 19, the air can flow more smoothly through the air intake box 15, thereby increasing the ventilation capacity of the air intake box 15.

[0038] The working principle of the utility model is as follows: the exhaust gas first enters the treatment box 2 through the air inlet hopper 3. In the treatment box 2, the exhaust gas passes through the filter assembly, in which the filter plate 5 is filled with activated carbon material. The design of these filter plates 5 makes the exhaust gas blocked when passing through the filter plate 5, thereby increasing the time the exhaust gas stays inside. At the same time, a baffle 6 is set at the air inlet to prevent the exhaust gas from directly entering the other side of the filter plate 5. The exhaust gas filtered by the filter plate 5 is then discharged into the environment through the air outlet hopper 4. During the discharge process, the guide block 11 blocks the possibility of the exhaust gas in the treatment box 2 passing directly, ensuring that the exhaust gas must pass through the filter plate 5 before entering the filter plate 5, avoiding the exhaust gas bypassing the filter plate 5 without being filtered.

[0039] At the same time, the structural design of the filter assembly also includes a positioning plate 8 and an air outlet slot 7. The inclined setting of the positioning plate 8 allows the airflow to pass smoothly when passing through the other side of the filter plate 5, ensuring the smooth flow of the exhaust gas, while the air outlet slot 7 ensures that the exhaust gas can be discharged smoothly after treatment. In addition, a rotating grille 9 is installed on the positioning plate 8. When the airflow passes through, the rotating grille 9 will open to ensure smooth airflow, and will close when the airflow stops passing, preventing the exhaust gas from flowing back or leaking, thereby ensuring the filtering effect.

[0040] In addition, waste residue collection and treatment is also an important function of the device. A collection component is arranged under the base 1, including a collection trough 13 and a collection box 14. During the waste gas treatment process, the filter component gradually accumulates waste residue, and the collection component is used to collect the waste residue. The collection trough 13 runs through the base 1 and is connected to the collection box 14, ensuring the centralized collection of waste residue for subsequent treatment or disposal.

[0041] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.

[0042] The utility model is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
