Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic precipitators, in particular to an anti-blocking device for an electrostatic precipitator ash hopper. Background Art

[0002] Electrostatic precipitator is an air purification device widely used in industrial fields. It uses a high-voltage electric field to deposit charged dust particles to remove suspended particles in the gas. In the structure of the electrostatic precipitator, the ash hopper is a key component used to collect and temporarily store dust captured by the electric field.

[0003] The design of traditional ash hoppers is relatively simple, relying mainly on gravity to accumulate dust and eventually removing it manually or mechanically. Under certain conditions, especially when dealing with gases with high humidity or high particle viscosity, the dust in the ash hopper is prone to form clumps, causing outlet blockage and affecting the operating efficiency of the entire electrostatic precipitator. Traditional ash hoppers usually need to be cleaned manually on a regular basis, which is not only labor-intensive, but may also cause the efficiency of the electrostatic precipitator to decrease due to untimely cleaning, and may even require shutdown for maintenance, increasing operating costs.

[0015] 1. The anti-blocking device for the ash hopper of the electrostatic precipitator can automatically identify the ash accumulation in the ash hopper and activate the cleaning mechanism in time through real-time ash accumulation monitoring of the load sensor and intelligent control of the electric control box. This automated monitoring and cleaning process not only reduces the need for manual intervention, but also ensures that the electrostatic precipitator can operate continuously in the best state, avoiding efficiency loss or shutdown caused by ash hopper blockage;

[0016] 2. The anti-blocking device of the ESP ash hopper is equipped with a scraper and a stirring rod that work together to not only effectively scrape off the accumulated dust in the ash hopper and push it to the outlet, but also break up the dust clumps and maintain the fluidity of the dust. This mechanism ensures that the ash hopper can effectively prevent blockage and keep clean even when the dust is humid or sticky.

[0017] 3. The anti-blocking device for the ash hopper of the electrostatic precipitator greatly reduces the workload of maintenance personnel through the automated dust cleaning process, making daily maintenance easier. The design of the switch valve, dust suction pipe and dust collection box allows the dust collected during the cleaning process to be directly transported to the designated dust collection container, simplifying the dust handling process and reducing the risk of dust exposure in the workplace.
