Boiler dust removal pulse bag filter is a kind of efficient dust removal equipment, which is widely used in the field of industrial dust control. It adopts pulse injection ash cleaning method, which has the advantages of high efficiency, low resistance and easy maintenance. This article will introduce the principle, characteristics, application and maintenance of boiler dust removal pulse bag filter in detail.
1. The working principle of the pulse bag filter.
The pulse bag filter is mainly composed of a box, a bag chamber, a pulse injection system, an ash discharge system and other parts. The dusty gas enters the bag chamber and is trapped on the surface of the filter bag by the filtering action of the filter bag. The purified gas enters the upper box through the filter bag mouth and is discharged from the air outlet. As filtration progresses, the dust on the surface of the filter bag increases, causing the equipment resistance to rise. When the resistance of the equipment reaches the set value, the ash cleaning system starts to work, and the filter bag is cleaned through the pulse injection device, so that the dust falls into the ash hopper. After cleaning, the filter bag starts to filter again until the set resistance value is reached again.
Second, the characteristics of the pulse bag filter.
1.Efficient dust removal: The bag filtration technology is adopted, which has a good capture effect on fine dust and high dust removal efficiency.
2.Low resistance and high efficiency: large spacing between filter bags, uniform airflow distribution, reduce secondary dust, and low equipment resistance.
3.Easy maintenance: The pulse injection cleaning method has automatic control function, which reduces the trouble of manual operation.
4.Strong adaptability: It can be applied to various types of dust control, and is widely used in electric power, metallurgy, chemical and other industries.
5.Environmental protection and energy saving: high dust removal efficiency, reducing dust pollution to the environment, in line with environmental protection requirements.
3. Application of pulse bag filter.
1.Power industry: Pulse bag filter is widely used in the power industry, mainly used for flue gas dust removal of coal-fired boilers. Through dust removal treatment, the dust content in the flue gas can be reduced and the pollution to the environment can be reduced.
2.Metallurgical industry: In the metallurgical industry, pulse bag filter is mainly used for the collection and treatment of iron ore powder, coal dust and other materials. Through dust removal treatment, the production environment can be improved and product quality can be improved.
3.Chemical industry: In the chemical industry, pulse bag filters are mainly used for the treatment of waste gases generated during various chemical reactions. Through dust removal treatment, the pollution to the atmosphere can be reduced, and the safety and stability of production can be ensured at the same time.
4.Other industries: In addition to the above industries, pulse bag filters are also widely used in dust control in ceramic, cement, wood processing and other industries.
Fourth, the maintenance of the pulse bag filter.
In order to ensure the normal operation and service life of the pulse bag filter, regular maintenance and maintenance are required. Specific maintenance includes:
1.Check the wear and tear of the filter bag: check the wear and tear of the filter bag regularly, and replace the filter bag in time if it is found to be seriously worn. At the same time, it is necessary to ensure that the screws are tightened when installing the filter bag to prevent air leakage.
2.Clean the ash hopper: clean up the ash in the ash hopper in time to ensure that there is no dust accumulation in the ash hopper, so as not to affect the normal operation and service life of the equipment.
3.Check the cleaning system: regularly check the operation of the cleaning system to ensure that the cleaning system can work normally. If any abnormal situation is found, it should be dealt with or replaced in time.
4.Check the box: regularly check the tightness and weld condition of the box, and deal with it in time if there is air leakage or weld cracking. At the same time, it is necessary to ensure that the inner wall of the box is smooth and thorny, so as not to affect the normal operation and service life of the equipment.
5.Clean the compressed air pipeline: Regularly clean the impurities and moisture in the compressed air pipeline to ensure the cleanliness and dryness of the compressed air. At the same time, it is necessary to check whether the pipe connection is tightly sealed and sealed, so as not to affect the normal operation and service life of the equipment.
