TWO-STAGE 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 cyclone contains a housing consisting of a cylindrical and a conic parts, a peripheral gas flow inlet represented by an inlet nipple, an exhaust device containing an exhaust pipe with a splitter for decontaminated gas inlet, a socket contained inside the housing with a water collector and a drain tube. The exhaust pipe is 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.

EFFECT: improved efficiency and reliability of the dust collection process, reduction of metal-intensity and vibroacoustic activity of the device in general.
