The battery cyclone includes a housing 1, divided into a chamber 2 of dusty gas, a chamber 3 of purified gas and a bunker 4 for collecting drums of the upper 5 and lower 6 tube plates. In the housing 1, in the direction of movement of the gases, several rows of cyclone elements 7 are installed, which have tapered 8 and cylindrical 9 parts, branch pipes

on the back of the cyclone elements, and their inlets 14 are directed perpendicular to the direction of the gas flow. The nozzles 11 of the axial exhaust gas are flush with the top covers 12 elements 7.

In the course of the gas movement, the cyclone elements are connected by successive portions of flat rectangular plates. In this case, the first plate 15 of each pair along the gas flow is located

The parallel plates 15 are aligned with the upper caps 12 of the cyclone elements 7 of the previous rows, and the plates 16, which are perpendicular, are connected to the upper caps 12 of the subsequent rows of rows and are directed tangentially to the cyclone surface facing the gas inlet.

The upper clamps are located in the chamber 3 of the cleaned gas, and the lower claws 13 of the latter along the gas path are parallel cyclone elements combined with the lower tube plate 6 and are located in the chamber 2 of the dusty gas.

The distance between the parallel plates and the bottom tube plate of the first downstream gas p and the cyclone elements is equal to the length of the cylindrical part of the cyclone elements with the gas inlet pipe, and each subsequent number is reduced by

Due to the tangential gas supply, it is twisted in the cylindrical part 9 of the cyclone element and in a downward spiral heaped gas is directed to the conical part 8 of the element and then to the picty collection hopper 4, where the separation of piti from gas occurs. Dust. besieged in the bunker, and ochshtsenny. the gas in the central part of the cyclone is directed upwards into the nozzle 11 of the axial exhaust of gases, from which only the cylindrical part in the first row of elements eliminates the turbulence of the gas flow and improves the operation of the cyclone.
