Air-cannon multipoint oscillation dust removing device for bag-type dust collector

Abstract

The invention discloses an air-cannon multipoint oscillation dust removing device for a bag-type dust collector. An air-cannon electric control device of the device is connected with an electromagnetic directional valve which is arranged on a rear cover of an air-cannon quick opening valve and communicated with the air-cannon quick opening valve. The electromagnetic directional valve and the air-cannon quick opening valve are connected with an air-cannon storage air cylinder through an internal channel respectively. A compressed air inlet pipe is connected with the electromagnetic directionalvalve. The air-cannon quick opening valve is communicated with horizontal pipes and vertical pipes in turn through pipelines. Conical impact air openings are formed on the vertical pipes. The vertical pipes are arranged between bags and have length which is identical with or a little shorter than the length of the bags. The conical impact air openings are reserved at different length positions ofall the vertical pipes, a plurality of conical impact air openings are reserved at the length positions, and each conical impact air opening is formed in a manner of facing the bag transversely. The air-cannon multipoint oscillation dust removing device for the bag-type dust collector provided by the invention has the advantages of large bag oscillation amplitude, good dust removing effect and long bag service life.

Description

Technical field: [0001] The invention relates to a dust removal device for a dust collector, in particular to an air cannon multi-point oscillation dust removal device for a bag dust collector. Background technique: [0002] In the field of dust collectors, the bag filter has its unique advantages as a dry dust collector. Because its working principle is that the dust-containing gas is directly filtered through the cloth bag, and the dust removal effect can reach more than 90%. Especially for ultra-fine dust, as long as the gap of the bag is small enough, it can be effectively filtered out. This is incomparable to other centrifugal, inertial, dynamic and other dust collectors. Of course, wet dust removal can also wash away tiny particles, but the mud treatment in wet method is very difficult, which also limits its scope of use. . [0003] Although the effect of the bag filter is good, it is necessary to clean the dust in time, because the gaps in the bag will be gradually...

Problems solved by technology

In this way, when the bag filter is used for a period of time, the air intake resistance to the fan will become larger and larger. When the dust removal effect is too small, the bag must be cleaned or replaced.
