Liaoning environmental protection dust removal equipment cleaning installation

Date of release:2018-10-25 Author: Click:

Installation of cleaning dust for environmental protection dust removal equipment: cleaning dust is an important measure to ensure the normal operation of environmental protection dust removal equipment. If the injection function and air volume of the pulse valve cannot effectively remove the dust cake formed on the dust-receiving surface of the filter bag, it will cause environmental protection dust removal equipment. The resistance (pressure difference between inlet and outlet) rises, the negative pressure at the dust source collection port decreases, the treatment air volume is reduced, and the working conditions of all systems are deteriorated. Once the resistance cannot be controlled and continues to rise, environmental protection dust removal equipment will be in a paralyzed state. Conversely, excessive dust removal will result in low resistance, which will cause particulate matter (especially fine particles) to be discharged and added, and affect the filter bag. Since the pulse valve's blowing function and gas volume are very important for the dust removal effect of environmentally friendly dust removal equipment, it also has Restricted and affected by various elements in the cleaning system, it is difficult for the pulse valve manufacturer to answer how many filter bags (filter area) a pulse valve can clean. Although some pulse valve manufacturing plants are also equipped with injection experimental equipment, due to the lack of special dust and special dust removal experimental equipment, at best, only the amount of air blown by the pulse valve under limited conditions and the pressure of each point of the filter bag during injection can be measured. distributed. Some large dust collector companies in China have bag filter test benches, which can determine the raw materials, caliber, length and number of combinations of filter bags, and can be used in different dust concentration, discharge concentration, filtration speed, pulse valves with different calibers and Under the conditions of the required equipment resistance and discharge requirements, the experiment determines the pulse valve cleaning function, which provides a certain scientific basis for the selection of the pulse valve and the planning of the cleaning system.
