TWO-STEP DUST COLLECTOR SYSTEM WITH INERTIAL DUST SEPARATOR Russian patent published in 2018 - IPC B04C1/00 

FIELD: dust collection equipment.

SUBSTANCE: invention relates to the dry dust collection technique and can be used in chemical, textile, food, light and other industries to clean dusty gases. In a two-stage dust collecting system with an inertial dust separator, comprising a body consisting of a cylindrical and conical parts, dusty gas flow injection, a dust collecting bin with a mechanical dust removal device, curtain and outlet branch pipe of purified gas, the curtain is made in the form of a package of chain and at least one continuous protective elements, fixed on a plate suspended on elastic elements to the body, chain-shaped barrier elements are evenly distributed over the entire area of the passage section of the body and along its length, and the solid barrier element is located with a gap relative to the walls of the body, a layer of a soft vibration damping material is applied to the surface of the body parts, for example VD-17 mastics, the ratio between the thickness of the metal and the vibration damping coating is in the optimum values range of 1/(2.5…4), wherein fine dust collecting apparatus includes a frame body with fences, a support part with a dust collecting bin and a dust collector mounted on the base, as well as the inlet and outlet ducts of the filter section of the dust collector with bag-type filters, respectively, with inlet and outlet nozzles, in this case, the collector is installed with injectors of the fire and explosion safety system with the control unit, which is connected electronically to the common microprocessor, the bag filter regeneration system with the pulse purging mechanism, which is provided with the control unit for each purge nozzle solenoid valve and is connected to the common regeneration control unit, which is connected electronically to the common microprocessor, temperature sensor is installed in the inlet duct of the filter section, the emergency dust level sensor is installed in the dust collecting hopper, and the thermal automatic sensor-detector is installed in the outlet box of the filter section, outputs of which are connected to a common microprocessor located in the control cabinet,and each of the nozzles of the fire and explosion safety system of the device includes a housing with a swirl chamber and a nozzle.

EFFECT: increased dust collection process efficiency and reliability.
