Description

Technical Field

[0001] The utility model relates to a dust collector used for removing dust from a biomass combustion furnace. Background Art

[0002] Biomass combustion furnace is a combustion equipment that uses biomass energy as fuel. It is mainly used in industrial fields such as heating, drying, and power generation. Its principle is to convert the heat energy generated by the combustion of biomass fuel into the required heat energy or electricity. The biomass combustion furnace consists of a combustion chamber, a feeding system, a smoke exhaust system, a control system, etc. The smoke discharged by the smoke exhaust system needs to be processed by a dust collector before being discharged.

[0003] A dust collector is a highly efficient dust removal device that collects and purifies dust by filtering dust-containing gases through filter bags. Its working principle is: after the dust-containing gas enters the dust collector, larger particles of dust are separated due to inertia and fall directly into the ash hopper, while finer dust is adsorbed on the surface of the filter bag. After being filtered by the filter bag, the clean gas passes through the filter bag and is discharged.

[0004] When the smoke discharged from the biomass combustion furnace is treated by a dust collector, due to the large flow rate of smoke generated by the combustion, long-term use will cause the bag surface to be blocked, and pulse dust removal is required for cleaning. However, it is difficult to ensure effective and complete cleaning, resulting in frequent cleaning and inconvenience in the use of the dust collector. In addition, large pulses will cause impact pressure on the bags, reducing the service life of the bags and increasing economic costs. Utility Model Content

[0035] In the present technical solution, the cleaning mechanism includes a pulser 16 and a pipe 17. The pulser 16 is fixedly connected to the outer wall of the outer shell 1.

[0036] In the present technical solution, the driving mechanism includes a motor 19 and a turntable 20. The motor 19 is fixedly mounted to the outer wall of the outer shell 1.
