 What are the common diseases of dust removal equipment in power plant?
The problem of bag filter in power plant is low operation efficiency. Excessive emission density of flue gas and dust will lead to the increase of bag filter load. Continuous operation will lead to damage of bag filter shell and its accessories, and even irreparable damage. If large equipment is used, the cost will be greatly increased High, economic benefits have a serious impact on the dust removal effect and resource utilization; when the power plant is in normal operation, the filter bag life of the bag filter is extremely short, and there will be wear in the process of use, especially at the opening of the filter bag and the middle and lower part of the filter bag, which is caused by the friction of the filter bag by the granular dust when filtering,

Poor operation efficiency Filter bag Short life:

Power plant Bag filter In the process of using and running, the problem is that the operation efficiency is low. In the process of dust collector operation, the emission density of flue gas dust is too high, which will lead to the increase of bag filter load. If the bag filter shell and its accessories are damaged, even irreparable damage will be caused. If large equipment is used, the cost of products will be greatly improved, and the economic benefits will be great It has a serious impact on dust removal effect and resource utilization ; During the normal operation of the power plant, the filter bag life of the bag filter is very short, and there will be wear in the process of use, especially at the opening of the filter bag and the middle and lower part of the filter bag. Because the granular dust will rub the filter bag when filtering, the maintenance cost of the filter bag is very high, and once the filter bag is damaged, the dust will enter the atmosphere once, which will cause great damage Lost.

The dust discharge container of the power plant dust remover is seriously worn and the dust deposit is easy to burn

Under normal working conditions, the bag filter will unload the dust after a certain period of time to clear the space for dust storage again. If the dust density is too high, the ash unloading rate will be high, and the ash unloading container will be worn during the process. Therefore, it needs to be replaced on time, but the cost of replacement is very high The dust is deposited in the dust collector. Under the condition of sufficient oxygen, a large amount of heat will be generated due to friction, which will lead to smoldering, which may seriously cause damage to the dust collector itself and cause losses, which not only affects the economic benefits, but also affects the work efficiency of the product.

The key parts of precipitator in power plant are easy to be blocked

The accumulation of dust makes some small pipes of the dust collector easy to be blocked, resulting in the channel not circulating, affecting production. If the dust blockage is not cleaned in time, it will seriously affect the work of the equipment, and the consequences are unimaginable.

Cause analysis and solutions of problems existing in dust remover equipment of power plant:

Bag filter for power plant Cause analysis of existing problems:

For wear, it is because there are more solid particles in the fly ash dust, which makes the filter bag and the ash unloading container easy to wear, especially in the movement of the dust discharge container In addition, there are many combustible substances in the dust. Once the ash is serious, the stored heat will produce smoldering, which will damage the filter bag and cause air leakage. The dust will flow into the atmosphere; There are also reasons for smoldering because of the poor sealing of the filter bag, which leads to good air circulation, which has a combustion supporting effect on smoldering. If the sealing is not good, dust will flow inside and outside the filter bag, which will block some small pipes, and cause a vicious circle. When using pulse jet, the frequency setting is not correct, resulting in increased cost and efficiency Small, causing unnecessary friction, resulting in equipment wear.

Solutions to the problems of bag filter in power plant:

In order to ensure the normal operation of the equipment in the power plant, the power generation mode of the power plant should be reformed to reduce the generation of dust and improve the production efficiency of the power plant. Regular inspection, maintenance and cleaning of the equipment should be carried out to ensure the normal operation of the equipment. This is also an effective way to fundamentally eradicate dust.

Improve the production status of the power plant, reduce the carbon content of dust, make full use of carbon, regularly check whether the sealing of filter bag is in good condition, replace the worn filter bag regularly, and use air flow to ventilate the small pipe regularly. The ventilation rate should be large, so that the pipe is not blocked and the dust can circulate normally.
