Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a dust collector with an anti-blocking function. Background Art

[0002] The equipment that separates dust from flue gas is called a dust collector or dust removal equipment. The performance of a dust collector is expressed by the amount of gas that can be processed, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. At the same time, the price, operation and maintenance costs, service life, and difficulty of operation and management of the dust collector are also important factors to consider its performance. Dust collectors are commonly used facilities in boilers and industrial production.

[0003] According to the patent announcement number: CN210964459U, a dust collector is provided, including a box body, and the left and right sides of the box body are fixedly connected with an air outlet pipe. The dust collector uses the main motor to drive the fan to exhaust air, and the air carries dust from the air inlet pipe through the air inlet channel into the interior of the motor box. Due to the pipe diameter and the effect of gravity, the dust suddenly decreases in speed and the effect of gravity, and most of the dust falls into the interior of the dust collecting pipe. The rest of the dust hits the dustproof net with the air, and a part of the dust is filtered out. Then the air carries the remaining dust into the filter bag. The purified air continues to move upward and filters the air through the filter net for the last step, filtering the toxic gas, and the clean air is discharged to the outside of the box through the air outlet pipe. The whole device is a mixture of physical filtration and bag filtration, and also uses a HEPA high-efficiency filter. In addition, the universal wheels can facilitate the movement of the device, and dust removal can be carried out efficiently.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, although it can solve the problem that the general dust collector is specific to a certain dust environment, but is not effective for other dust environments, and the dust removal strength for particularly small molecules in the dust is not strong enough, but in actual use, the filter will be clogged after long-term use, and the filter needs to be replaced or cleaned frequently, which increases the maintenance cost. In addition, the clogged filter will increase the resistance of the airflow, which increases the pressure difference inside the dust collector, further reducing the dust removal efficiency.
