SU434965A1 - GAS CLEANING FILTER - Google Patents

Description

one

The invention relates to gas cleaning and dust collection and is intended for use in industries associated with the capture of harmful dust materials, such as dust, soot, complex phosphoric fertilizers and chemical compounds, as well as expensive materials (diamond, dust from gold processing, etc. .).

A filter for cleaning gases is known, comprising a housing divided by a partition with diffusers into a cleaned chamber and a dusty gas chamber in which filter sleeves are located attached to diffusers.

In the event of damage to the sleeves, the known filter fails.

The purpose of the invention is to increase the reliability of the filter.

For this purpose, additional sleeves are located in the clean gas chamber, which form an enclosed space with the sleeves of the dust pelvis chamber.

The drawing shows the proposed filter.

The filter consists of a housing divided by a partition 1 with diffusers 2 on the chamber 3 cleaned and chamber 4 of dusty gas, in which the lower filter sleeves 5 are located, stretched on the frame 6 and attached to the diffusers 2. At the bottom of the frame 6 a dust collector 7 is installed a check valve 8. In the clean gas chamber there are upper additional frameless sleeves 9, inside of which nozzles 10 are installed to purge sleeves 5 and 9 connected to solenoid valves 11. Upper frameless additional sleeves 9 adjoining ineny to the diffusers 2 to form the lower sleeve chamber 5 dusted

gas closed space.

The filter works as follows. Dust gas enters chamber 4, seeps into the lower sleeves 5 and passes through the diffusers 2 into the upper sleeves 9. The cleaned gas is removed from the filter. When a predetermined filter resistance is reached in the cavity of the sleeves 5 and 9, a compression air pulse is applied through the connector 10 by means of electromagnetic valves 11, which ejects the cleaned gas from the upper sleeves 9 into the lower 5, creating a vacuum in the upper sleeves and pressure in the lower ones . The dust from the lower sleeves 5 is discharged into a common hopper, and the dust dropped from

the internal surfaces of the upper sleeves 9, falls into the collector 7 and, through the check valve 8, which opens as a result of the excess pressure inside the sleeve during the regeneration period, is thrown into the chamber of dust-laden gas.
