vacuum fume extractor classification because the filter material is folded into a cylinder, the filter material layout density is large, so the dust removal mechanism is compact, small volume; Filter cylinder height is small, easy to install, use and maintenance workload is small; The filter area of the same volume dust collector is relatively large, the filter wind speed is small, and the sniper is not big. Filter material folding requires strict sealing at both ends and no air leakage, otherwise it will affect the dust removal effect. The cylinder type dust collector is composed of air inlet pipe, air exhaust pipe, box, ash hopper, dust cleaning device, filter drum and electronic control device. The arrangement of the filter cylinder in the dust collector is very important, the filter cylinder can be arranged vertically on the box flower plate of the dust collector, can also be arranged tilted on the flower plate, fixed with bolts, and the rubber pad, the lower part of the flower plate is divided into the filter chamber, the upper part is divided into the clean gas chamber, the filter cylinder is fixed with bolts, the convenient method is automatic locking device and rubber pressing device, these two methods, It is convenient for installation and maintenance. The tilt Angle of the dust hopper should be fixed according to the rerest Angle of the dust, which should not be less than 60 degrees. The discharge valve of the cartridge dust collector should be tight. The height of the clean chamber of the cylinder dust collector should be convenient for the installation and maintenance of the pulse jet device.
The following, a detailed talk about the vacuum fume extractor classification dust collection cover setting method:
First, the external dust removal cover is adopted, and the enclosure is installed at the lower part of the cover as far as possible to reduce the scope of dust suction.
2. The setting of dust collecting hood shall not hinder operation and maintenance.
3. Dust bearing air controlled by dust collecting hood does not pass through the operator's breathing area.
Four, under the condition of permitting, as far as possible the use of closed cover, so that the dust and the operator separate, and limited in the local.
5. When installing the receiving external dust cover, the direction of vacuuming should be consistent with the direction of dust particle ejection.
Vi. When setting the external dust removal cover, the cover mouth should be as close as possible to the place where dust occurs.
vacuum fume extractor classification is the use of the filter bag made of fiber woven material to filter dust, so that dust air purification. When the dust accumulates on the filter bag to the corresponding degree, the filter bag is sprayed and cleaned by means of compressed air in the form of pulse, so as to achieve the purpose of cleaning the filter bag. The dust bag is attracted by the fan, and the dusty air enters the dust chamber through the air inlet at the bottom of the lower box. The dust particles are blocked in the outer wall of the filter bag, and the air purified through the filter bag is discharged from the fan outlet. With the increase of dust particles on the surface of the filter bag, the resistance of the dust collector also increases correspondingly, gradually weakening the filtration capacity. When the resistance reaches the corresponding degree, it needs to be cleaned. At this time, the pulse control instrument sends a signal regularly, and opens the electromagnetic pulse valve step by step, so that the compressed air in the air bag passes through the pulse valve through the small hole on the spray pipe, and ejects a high pressure jet air into the filter bag. The filter bag expands, and then the middle finger is sprayed, and the filter bag shrinks sharply again, so that the dust accumulates on the outer wall of the filter bag is shook off, and the filter bag is in good working condition. Since the dust removal process is carried out in turn, and the dusty air is not cut off all the time, the dust removal capacity of the dust collector basically remains unchanged during the working process. In order to adapt to the requirements of different working conditions, the pulse interval and pulse width of the pulse controller can be adjusted arbitrarily.
vacuum fume extractor classification structure is composed of air intake pipe, exhaust pipe, box, ash bucket, ash cleaning device, flow guide device, air distribution plate, filter cylinder and electronic control device, similar to air box pulse bag dust collection structure. The arrangement of the filter cylinder in the dust collector is very important. It can be arranged vertically on the flower plate of the box body or tilted on the flower plate. From the effect of dust removal, the vertical arrangement is more correct. The lower part of the flower plate is the filter chamber, and the upper part is the air box pulse chamber. A airflow distribution plate is installed at the inlet of the dust collector.
vacuum fume extractor classification operation is good or bad, the speed of pressure loss rise and ash cleaning effect has an important relationship. In the desulfurization dust collector, the dust particles are easy to plate on the surface of the filter cylinder, resulting in the surface adhesion of the filter material. At this time, if you want to achieve a more ideal cleaning effect, you need a better spray pressure and a more frequent spray frequency, which will cause energy loss. Therefore, the selection of appropriate filter materials has an impact on the spray system. In many projects, there exists the problem of bad cleaning in the filter cylinder backblowing. During the pilot run of the boiler dust removal treatment project, it is found that the early cleaning effect is better than expected, but it does not meet the design requirements after working for a period of time. By adjusting the injection interval of the pulse valve, the effect is still not very ideal. On the basis of changing the nozzle, the injection pressure is increased to solve the problem of poor cleaning in the process of back blowing.
