They are suitable for removing dust from flue gas and can be used in situations where the flue gas temperature is high and the pressure is high. Practice has shown that the larger the amount of flue gas treated, the more economical the investment and operating costs of using electrostatic precipitators, so they are widely used.

[0003] After searching, the Chinese patent with publication number CN218359935U discloses an air intake duct for an electrostatic precipitator based on flue gas treatment, wherein the two ends of the air-blocking belt respectively pass through two reel-up boxes and are connected to the reel-up rollers in the reel-up boxes, the air-blocking belt is slidably arranged between the two side edges and fits with the inner side of the grid plate, and a strip opening is opened on the air-blocking belt, and the strip opening is arranged parallel to the reel-up box.

[0004] However, similar to the above-mentioned electrostatic precipitator based on flue gas treatment, the size of the strip opening is fixed and cannot be changed according to the gas flow rate, flow velocity and specifications of the dust collector in the pipeline, thereby affecting the uniform distribution of the flue gas. Therefore, a new solution is needed to solve this problem. Utility Model Content

The movement of slide plates 1 3 and slide plate 2 4 is controlled by a driving component to adjust the positions of slide plates 1 3 and slide plate 2 4 so that the smoke can pass through different positions of the filter plate 2.
