The characteristics of chemical plant dust remover are as follows
The dust remover in chemical plant is mainly composed of box, pulse valve, conveyor, ash unloading valve, electric control cabinet, air compressor, etc. it is divided into three stages: filtration, ash cleaning and transportation to complete dust purification.
1. Pulse dust collector has the advantages of short cleaning cycle, low energy consumption and long filter bag life.
2. The opening of filter bag adopts elastic expansion ring, which has good sealing performance and is firm.
3. The utility model has the advantages of convenient unloading frame and reduced friction with filter bag.
4. The inlet and outlet air ducts are arranged compactly and the air flow resistance is small.
5. When changing the dust removal cloth bag, first pull out the skeleton, the filter bag falls into the ash hopper, and takes it out from the manhole, so it is convenient to change the bag.
6. The maintenance and bag changing can be carried out in different rooms under the normal operation condition of the system without stopping the fan of the system.
Working principle of dust collector in chemical plant:
The dust remover is called the dust remover to separate the dust from the flue gas. Everyone has the experience of wearing a mask, which is a simple filter and dust removal equipment. The dust removal mechanism of dust removal equipment is very simple. It is realized by mechanical interception of fly ash particles in flue gas by filter materials, just like the dust removal mechanism of mask. But in addition, the first received fly ash particles also form a stable and dense layer of ash on the surface of the filter material (generally known as filter cake or filter bed), which also plays a very good filtering role, especially for the dust removal equipment with woven cloth as filter bag, this layer of filter bed plays the main filtering role.
How to maintain and manage bag filter in chemical plant?
There are three reasons why the maintenance of bag filter is easy to be ignored: first, the bag filter is stable in operation, with less damage and accidents The damage of bag filter in chemical plant is often manifested as the damage of filter bag, but the service life of filter bag has no definite definition, and the length of service life varies with bag quality and application occasion; third, small and medium bag filter does not have full-time management and maintenance personnel. In view of this situation, the maintenance and management of bag filter should be paid attention to, and the following matters should be paid attention to:
A. carry out maintenance management according to the key points in the table;
B. maintenance and management personnel shall be familiar with general maintenance knowledge and special requirements of dust collector;
C. before finding out the problem, do not operate rashly, so as to avoid major failure.
