Description

A new type of dust removal bin

technical field

The utility model relates to the technical field of application of dust removal bins, in particular to a novel dust removal bin.

Background technique

The dust removal bin is a kind of equipment that separates dust particles from the flue gas. It is often used in cement and other powder processing plants or processing plants with large smoke particles. The dust collector is mainly composed of an upper box, a middle box, an ash hopper, It is composed of air inlet equalizing pipe, support filter bag, injection device, ash unloading device, etc. The dust-laden gas enters the ash hoppers of each compartment from the air inlet uniform flow pipe of the dust collector, and under the guidance of the ash hopper diversion device, the large particles of dust are separated and directly fall into the ash hopper, while the finer dust enters the ash hopper evenly. The middle box is adsorbed on the outer surface of the filter bag. The clean gas enters the upper box through the filter bag and is discharged into the atmosphere through the off-line valves and exhaust pipes. However, after a certain number of years in the traditional dust removal bin, hardening occurs. The problem is that the substances that cause hardening are related compounds produced during the smelting process using scrap steel as raw material in the steelmaking process. Because the paint surface of scrap steel contains zinc, the compound after smelting contains zinc hydroxide (Zn(OH) ₂ ) and Zinc oxide (ZnO), according to its physical form, zinc oxide will not cause hardening problems, so the substance that causes hardening is zinc hydroxide, dust particles and dust accumulate on the inner wall of the ash hopper and the overall device, causing accumulation and cannot be disposed of. The volume of the device will become smaller, and the corrosiveness of dust particles will also cause irreparable damage to the device and reduce the service life of the device.
