Description

(5) DUST COLLISION DEVICES

one

The invention relates to devices for the purification of air and gas from mechanical impurities and can be used in all industries related to the purification of gas streams.

The closest to the proposed technical essence and the achieved result is a dust removal unit: a device comprising a housing, an inlet and an outlet for gas. SlaveMOOT device, flushing device and perforated partition 1.

A disadvantage of the known device is the insufficient degree of purification of the dusty gas.

The purpose of the invention is to increase the efficiency of the gas cleaning process.

This goal is achieved by the fact that in a dust collecting device, including a housing, an inlet and an outlet for gas, a sludge removal device, a flushing device

and a perforated partition, the partition is equipped with a connecting rod, a hinged, parallelogram mechanism.

The height of the partition H is determined by the ratio

where W is the gas velocity in the partition; and) is the angular velocity of rotation of the cranks of the articulated parallelogram mechanism.

Claims (2)

The dust collecting device comprises a housing 1 which includes inlet 2 and outlet 3 nozzles and a bin k for collecting sludge, a perforated partition 5, two flexible sealing housings 6 and 7, a flushing device 8, the partition 5 is divided into a number of channels of the same type 9 and rigidly connected with a connecting rod 10, which is hingedly connected with two (or more) cranks 1 1, in the same way together with the hinge parallelogram. Counterweights 12 are attached to the cranks 11. One of the crankshafts is driven and driven by the engine 13. The dust collecting device operates as follows. The partition wall 5, using a hinged parallelogram, imparts translational motion along a circular trajectory. Then through the pipe 2 serves dusty gas, pass it through the partition 5 and the purified gas outlet through the pipe 3. Dusty gas, the passage through the wall 9 of the partition 5, gets together with them the same movement. In this case, particles of mechanical impurities that are carried by the gas acquire relative motion (relative to the partition) along the screw lines. The radius of the helix depends on the particle mass, the viscosity of the gas, and the velocity of the forward movement of the partition and is determined by the formula VA2 + Sh3 / g J is the gas viscosity; p is the particle density; (5 is the particle diameter; R is the radius of the rotor's circular trajectory; tjJ is the angular velocity of rotation of this radius. The helix pitch h is equal to L-71Г W - W where W is the gas velocity in the mouth of the pipe. that they are deposited on the walls of the channels 9 of the partition 5. Moreover, if the height of the partition H is not less than the pitch of the helix, i.e., then a particle whose helix radius is greater than or equal to the radius of the circle inscribed in the channel section is inevitable but it will touch the walls of the canal and will be caught. For such mastics, the partition is not permeable. At the height of the partition, less than the magician of the helical lines of particles, the cleaning efficiency of the dust collecting device decreases, since a part of the particles, without completing the full turn of the helix, removes from the channel without touching its walls. The dust collecting device is not fully used. About the dust that has settled on the walls of the channels 9 of the partition 5 is periodically or continuously washed into the bunker k with a flushing device 8. Due to the fact that in the proposed dust collecting device stve partition performs reciprocating movement along a circular path, the energy proportional to the square sectional peregodki, just like performance. For this reason, the specific energy consumption for cleaning is relatively small and remains unchanged at any performance. The use of the proposed dust removal device is particularly efficient when cleaning large volumes of gas. Claim 1. A dust removal device comprising a housing, an inlet and an outlet for gas, a sludge removal device, a flushing device and a perforated partition, characterized in that, in order to increase the efficiency of the gas cleaning process, the partition is equipped with a connecting rod articulated parallelogramme mechanism, 2. The device according to claim 1, about tl, and that the height of the partition H is determined by the ratio H 2 E where W is the gas velocity in the partition; - the angular velocity of the spikes of the hinge-parallelogram mechanism.
