Description

Filter cylinder of dust remover

Technical Field

The utility model relates to a filter cartridge formula dust remover technical field, concretely relates to can avoid dust after the blowback to waft again and be detained at a triangle-shaped dust remover of straining on a section of thick bamboo and strain a section of thick bamboo.

Background

The filter cartridge type dust remover mainly comprises an inertia separation part and a filter cartridge filtering part, and adopts a unit module combined structure. A group of particle inertia separators and a set of filtering filter cylinders are arranged in the filter. The dust enters the dust remover through a side inlet or a top inlet by a negative pressure airflow generated by the fan through a pipeline, the dusty airflow passes through the inertial separator, and large particles carried in the airflow are directly separated into the dust collecting cylinder due to the gravity inertia effect, so that the first-stage intercepting and purifying purpose is achieved. When a small amount of dust is blocked by the filter element and deposited on the surface of the filter element and reaches a set value, the pulse electromagnetic valve is automatically opened, compressed air flows through the pipeline and flows back to the back flushing cleaning system, so that dust particles deposited on the filter element are separated from the surface of the filter element and fall into the dust collection barrel under the action of high-pressure air flow, the surface of the whole filter element is cleaned, and the optimal filtering state is always kept. The purified air is discharged from the air duct through the fan.

In the process that the dust-containing gas enters the interior of the dust remover from the gas inlet at the lower part of the dust remover, larger particles (with the diameter of 100 mu m) are firstly settled; smaller particles (0.1-50 μm in diameter) are adsorbed on the surface of the filter cartridge in the air treatment chamber. The purified air passing through the filter cartridge is exhausted through the exhaust chamber. When the running resistance of the equipment reaches a certain value, the pulse control instrument triggers the electromagnetic valve to open, compressed air (P is 0.5-0.6 Mpa) is blown into the filter cylinder through the blowing pipe, and dust particles fall off under the action of instantaneous high-pressure airflow, so that the filtering resistance is reduced to finish the dust removal and ash removal process. The dust on the surface of the filter cylinder is periodically cleaned, so that the running resistance of the equipment is relatively stable, and the dust removal device is an important link for ensuring the normal work of a dust removal system.

A traditional section of thick bamboo dust remover of straining is circular, and when the blowback cleaned, the upper filter cartridge surface dust fall back on the surface of straining a section of thick bamboo of lower floor after the blowback, and the blowback cleans the effect poorly, has increased the energy consumption, has increased manufacturing cost, has increased the plant maintenance frequency and has maintained the cost.
