Technical Field

[0001] This utility model relates to the technical field of baghouse dust collectors, and in particular to a baghouse dust collector for a semi-dry desulfurization and denitrification system. Background Technology

[0002] A dust collector or dust removal equipment is a device that separates dust from flue gas. A baghouse dust collector, also known as a filter dust collector, is a dry, high-efficiency dust collector that uses bag-type filter elements made of woven fiber fabric to capture solid particles in dust-laden gas. Its working principle is that dust particles are intercepted by colliding with the filter fibers due to inertial forces as they wrap around the fibers.

[0003] However, in the existing technology, when treating flue gas from semi-dry desulfurization and denitrification, bag filters are required. When filtering flue gas, the flow of flue gas in commonly used bag filters can easily cause one side of the filter bags inside the filter to be used frequently while the other side is used less, resulting in dust accumulating on one side and affecting the filtration and dust removal effect.

After the flue gas enters the dust removal chamber 201, it is filtered by the filter bags 305. When the device is running, the external controller starts the motor 207. The motor 207 drives the mounting plate 301 to rotate through the gear 208 and gear ring 302, so that the multiple filter bags 305 at the bottom of the mounting plate 301 rotate synchronously, filter the flue gas evenly, prevent dust from accumulating on one side, and improve the filtration effect.

[0040] After prolonged filtration, the electric air pump 401 can be started by an external controller.
