Description

Technical Field

[0001] This utility model belongs to the field of electrostatic precipitator technology, specifically relating to a novel heat-free and anti-clogging structure for electrostatic precipitators. Background Technology

[0002] An electrostatic precipitator (ESP) is a highly efficient and widely used industrial flue gas purification device, primarily used to remove solid particulate matter (dust) and liquid droplets (mist) from gases (usually flue gas). Its working principle is based on a high-voltage electrostatic field that ionizes the gas, causing dust particles to become charged and collected onto electrodes under the influence of the electric field. ESPs are mature, efficient, and reliable large-scale industrial flue gas dust removal equipment, particularly adept at handling high-temperature, high-volume, and fine-particulate conditions. Their high efficiency and low resistance have long made them dominant in heavy industries such as power generation, cement, and metallurgy. However, when ESPs are operating, fly ash caking and clogging in the ash hopper can easily occur, increasing energy consumption and maintenance costs significantly. To achieve the goal of energy-saving, reliable, and low-maintenance ESPs, a new type of heat-tracing-free anti-clogging structure for ESPs has been designed. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-3 This utility model provides the following technical solution: a novel electrostatic precipitator structure with heat tracing-free anti-clogging, comprising an adsorption box 1, a suction pipe 2 installed on one side of the adsorption box 1, a conveying pipe 3 installed on the other side of the adsorption box 1, a first support column 13 installed inside the adsorption box 1, a connecting column 14 installed below the first support column 13, an anode plate 15 installed below the connecting column 14, an ash hopper 6 installed below the adsorption box 1, an ash outlet 7 installed below the ash hopper 6, a first bottom plate 8 installed on one side of the ash hopper 6, and a blower 9 installed on the upper side of the first bottom plate 8. A flexible hose 10 is installed at the output end. A connecting rod 12 is installed on the inner side of the ash hopper 6. A gear 11 is installed on the other side of the connecting rod 12. A snap-fit ​​plate 20 is movably installed on the inner side of the gear 11. A second base plate 19 is installed on the other side of the snap-fit ​​plate 20. A motor 16 is installed on the upper side of the second base plate 19. A rotating shaft 17 is installed at the output end of the motor 16. A bevel gear 18 is installed on the other side of the rotating shaft 17. A fixing block 21 is installed on the lower side of the second base plate 19. Fixed air supply pipes 22 are installed on both sides of the fixing block 21. An air outlet pipe 23 is installed on the other side of the fixed air supply pipe 22.

[0015] In this embodiment: by setting a smooth coating on the inner wall of the ash hopper 6, it is easier and more effective to blow the dust generated on the surface of 6 into the ash outlet 7. The material of the smooth coating is polytetrafluoroethylene.

[0016] In this embodiment, by setting the tilt angle of the ash hopper 6 to be greater than 65 degrees, the normal pressure between the fly ash and the hopper wall is directly reduced, and the friction is significantly reduced.

[0017] In this embodiment: by setting an insulation layer to tightly wrap the entire ash hopper 6, the temperature of the ash hopper wall is always higher than the flue gas dew point temperature, preventing water from precipitating out.

[0018] The working principle and usage process of this utility model are as follows: After installation, first connect the suction pipe 2 to the flue gas conveying pipe, then turn on the motor 16, causing the motor 16 to drive the rotating shaft 17 to rotate, thereby rotating the bevel gear 18. The bevel gear 18 meshes with the gear 11, allowing the bevel gear 18 to rotate on the surface of the gear 11. The fixed air supply pipe 22 mounted on the fixed block 21 will also move with the rotation of the bevel gear 18. By turning on the blower 9, air is introduced into the fixed air supply pipe 22 through the hose 10, resulting in air being blown out at the air outlet 23. When the generated dust falls into the dust hopper 6, it is... With its excellent insulation, the temperature of the ash hopper wall is always higher than the flue gas dew point temperature, preventing water precipitation. Furthermore, by using an ultra-smooth, low-surface-energy lining material, the friction and adhesion between fly ash and the wall surface are significantly reduced. Therefore, the air blown by the outlet duct 23 can easily blow the dust that falls on the ash hopper 6, making the device better able to prevent ash hopper blockage and fundamentally solving the problem of ash hopper blockage. This achieves the working goals of energy saving, reliability, and low maintenance, greatly reducing the operating cost of the electrostatic precipitator. All electrical equipment in this device is powered by an external power source, and all motors in this device are connected and controlled by a PLC control system.
