a duster yes Cartridge filter The main component of a part, but because of the long-term use will appear some faults, the following we for the dust collector some of the more common problems students to analyze and answer. A device that separates dust from flue gas. The performance of the dust remover is expressed by the amount of gas that can be treated, the resistance loss of gas passing through the dust collector and the dust removal efficiency. The dust collector is composed of filter element or pulse jet. According to the installation methods, the cartridge dust remover can be divided into inclined plug-in type, side mounted type, hoisting type and top mounted type. It can be divided into fiber filter, filter cartridge, filter cartridge, etc.

1. If the dust collector can not receive the dust, and the dust concentration released exceeds the standard, what will happen?

A: the cylindrical dust collector is a very effective dust removal equipment, with dust removal efficiency up to 99.99%. From the dust emission at the outlet of the dust remover, the dust emission can be found in the following aspects:

The gap between the new installation of clean dust removal filter bag (1) is relatively large. At the beginning, it was not put into the bag filter to achieve the best state, and the qualified rate of dust was high. The dust collector is composed of filter element or pulse jet. According to the installation methods, the cartridge dust remover can be divided into inclined plug-in type, side mounted type, hoisting type and top mounted type. It can be divided into fiber filter, filter cartridge, filter cartridge, etc. During the use of the dust on the surface of the deposition formed in the outer layer of the precipitator dust, the outer surface of the dust remover will make the gap smaller, dust removal efficiency, dust filter is very difficult to drill into the gap.

(2) Check whether the installation enterprise of dust remover is correct. The filter chamber is usually separated from the filter chamber by the air ring inserted in the box body. If we didn't install it properly at first, the elastic expansion ring could not be fully closed with the flower plate hole, resulting in some untreated dust containing flue gas treatment directly and economically entering the air purification chamber, and dust emission occurred at the outlet of dust removal technology equipment. At the same time, pay attention to the safety inspection of bag mouth installation. If there is a gap, it should be pressed and sealed immediately.

2. What about dust clogging pores?

Answer: (1) for the time being, dust removal can be strengthened to eliminate the blockage of cloth bags;

(2) Partially or completely replace the blocked bags;

(3) Adjust installation and operation conditions;

(4) The cleaning time is too short and the cleaning cycle is too long.

When the paste bag occurs, we should first analyze its causes, aiming at the specific main reasons, we can take some corresponding measures to observe whether the students have been effectively improved or solved. If the effect is not obvious, you can choose to clean the cloth bag. If the dirt dust blocking the bag cannot be cleaned off, you can only replace the cloth bag.

3. What is the reason that the bag life is not aging?

And (1) because of abnormal high temperature hardening;

(2) Through the action of acid, in contact with the reaction alkali, organic solvent vapor or oxide;

(3) It reacts with water;

(4) The dust catcher is too loose or too tight;

(5) Incorrect operation.

In the actual conditions, the patch bag is more complex, for specific circumstances, we must start to analyze the conditions of smoke, dust, dust remover, operation control and other related factors, to understand the real patch inducing factors, in order to avoid and solve the problem.

4. How to make the dust remover play its best role?

A: timely maintenance and use of scientific methods, according to the dust can not only send out the maximum performance, but also in the use of extended 3-5 months of use, dust collector, to prevent the dew point of gas below the cooling to the private room, especially in the use of negative pressure dust removal equipment, should pay more attention. When the temperature is lower than the dew point, the bag filter becomes wet, so that the dust collected in the bag can not be removed. So try not to pay attention to the temperature higher than the dew point temperature.
