[0002] Organic waste gas treatment refers to the treatment work of adsorbing, filtering and purifying organic waste gas generated in the industrial production process. In the process of organic waste gas treatment, a variety of technical measures are used to reduce oil loss, reduce the amount of organic solvents or exhaust gas purification through different ways to eliminate organic waste gas pollution. In order to prevent pollution, in addition to reducing oil loss and reducing the amount of organic solvents to reduce the generation and emission of organic waste gas, exhaust gas purification is a practical treatment method;

[0003] Among them, the existing patent with announcement number CN219168010U discloses an organic waste gas treatment device, including a box body, an air inlet is provided on one side of the box body, an air outlet is provided on the side opposite to the air inlet, a filter block filling bin is detachably provided in the box body, the filter block filling bin is arranged between the air inlet and the air outlet, and the top cover of the box body is provided with an opening, and the opening is adapted to the filter block filling bin; but the above patent only filters through a single filter block, so that the filter block needs to be replaced frequently, which increases the labor intensity of the staff and increases the cost of filtration processing. At the same time, when the filter block is saturated with adsorption and cannot be replaced in time, the waste gas cannot be filtered, resulting in waste gas discharge and air pollution. Therefore, there is a defect of a relatively single filtering method, which cannot meet the customer's usage needs. Therefore, the technicians in this field provide a laboratory oil-containing low-concentration organic waste gas treatment device to solve the problems raised in the above background technology. Utility Model Content
