Abstract
The invention discloses a bag-type dust collector, and an application method thereof, and belongs to the technical field of environment-friendly equipment design. According to the application method, impact effect of entering of dust-containing gas into the bag-type dust collector is alleviated via utilization of the buffering effect of a baffle plate provided with baffle plate fan blades; in back flushing process, helical blades in a cloth bag are driven by back flushing gas to rotate, so that centrifugal force is generated, and high efficiency cleaning of all the corners of the cloth bag is realized; most large particles fall into a dust bucket directly because of the interception effect of the baffle plate fan blades, and influences on back flushing effect caused by absorption of too many large particles onto the surface of the cloth bag are avoided. In application process, dust on the surface of the cloth bag falls into the dust bucket without a plurality of times of back flushing, so that energy consumption is reduced, and problems in the prior art that direct impact of the cloth bag by the dust-containing gas is caused, and back flushing efficiency is low are solved.
Description
technical field [0001] The invention discloses a cloth bag dedusting device and an application method thereof, and relates to the technical field of environmental protection device design. Background technique [0002] At present, dust-containing gas is mostly treated with bag filter for filtration. Its working principle is to introduce dust-containing gas into the box of bag filter through connecting pipes. It is adsorbed on the cloth bag, and the purified gas is discharged from the cloth bag, so as to achieve the effect of air purification. However, because the gas connecting pipes of the existing bag filter are directly connected to the upper side of the middle box of the bag filter, the flow rate of the dusty gas entering the box will increase under the action of the induced draft fan, and the inertial force The high-speed dust-containing gas entering the box enters the box directly through the bag and then is discharged from the gas outlet of the upper box, and the oth...
