DUST COLLECTION SYSTEM BY KOCHETOV Russian patent published in 2010 - IPC B04C9/00 

FIELD: mechanics.

SUBSTANCE: invention is related to dust collection machinery. The dust collection system contains a cyclone representing the first decontamination stage and connected to the filtering element representing the second stage of removal of dust from gas-and-air mixture. The spiral-and-conic cyclone contains a housing consisting of a cylindrical part and an inverted cone, a spiral gas flow inlet represented by an inlet nipple, an inner cone forming a circular slot together with the inverted cone, a bin with a gate and an exhaust pipe for decontaminated gas outlet connected to the hose filter filtering chamber via an air duct. The hose filter filtering chamber is shaped as a cabinet with side doors for removal of vertically position filtering elements represented by filtering hoses. The decontaminated gas outlet flange is located inside the decontaminated gas chamber positioned over the filtering chamber, its cross section dimensions equal to those of the flange for inlet of gas to be decontaminated into the filter which is additionally equipped with a temperature sensor mounted inside the filtering section housing. Mounted inside the dust collection bin is an emergency dust level sensor; mounted inside the filtering section outlet box is an automatic thermal annunciator sensor. The above sensors outputs are connected to the governing controller. In the filter filtering section outlet box a manifold is mounted with nipples for connection to the fire extinguishing system.

EFFECT: improved efficiency and reliability of the dust collection process.
