There are many dust removal equipment used in the existing industrial dust and flue gas pollution control, such as electrostatic precipitators, etc. Most of these equipment have complex structures, require high investment costs, have complex dust removal processes, and have low efficiency.

[0003] For example, a dust removal pipe drainage device with announcement number CN216954089U includes a dust removal pipe, a water receiving box and a drainage pipe. The dust removal pipe is provided with an arc-shaped opening at the lower part, the water receiving box is fixedly installed at the arc-shaped opening position, a water outlet is provided at the bottom of the water receiving box, and a threaded joint of an integrated structure is provided at the bottom of the water receiving box at the water outlet position. One end of the drainage pipe is connected with the threaded joint, and a solenoid valve is installed on the drainage pipe. A metal filter is detachably installed inside the water receiving box, and a liquid level sensor is fixedly installed outside the water receiving box. The liquid level sensor controls the opening of the solenoid valve through a PLC, and the condensed water in the dust removal pipe passes through The arc-shaped opening enters the water collecting box. When the water in the water collecting box reaches the position of the liquid level sensor, the liquid level sensor sends a signal to the PLC, and the PLC controls the solenoid valve to open. At this time, the water can be discharged through the drain pipe, which improves the on-site environment, improves the dust removal effect, and reduces the labor of personnel to clear the blockage after the dust removal pipeline is blocked. However, the device is not convenient for overall spraying and dust reduction of the flue gas to be treated, causing some flue gas with more dust to directly contact the filtering equipment, making the dust in this part of the flue gas more easily adhere to the filtering equipment, thereby hindering the subsequent flue gas dust reduction and filtering effect, which makes the device have limitations.
