Bag dust collector

Description

Pulse bag dust collector is widely used in building materials, cement, metallurgy, machinery, chemical and refractory industries dust removal system. Especially suitable for cement plant crushing, packaging, warehouse roof, clinker cooling machine and all kinds of mill dust collection system. In addition, the air box pulse bag type dust collector, which sets the advantages of separate chamber reverse blowing and pulse injection and other types of dust collectors, overcomes the shortcomings of insufficient kinetic energy strength in the separate chamber reverse blowing, filtering and cleaning at the same time, so that the bag type dust collector increases the adaptability of use and improves the dust collection efficiency.

The pulse-bag dust collector is used to clean the dust by box. When cleaning the dust, it is isolated and rotated by box to avoid the secondary flying problem of the spray-type pulse-bag dust collector. At the same time to ensure the effect of compressed air cleaning, the whole box design uses the inlet and outlet main structure, the ash bucket can be extended to the inlet main pipe, so that the dust containing gas into the expanded ash bucket directly to achieve the effect of pre-collection of dust.

Performance Advantages

• High dust removal efficiency:The dust removal efficiency of air box pulse bag dust collector can reach more than 99.9, and the dust emission can be controlled below 30mg/Nm3. And can handle 100g/Nm3 of high concentration of dust.
• Good sealing effect:Advanced sealing measures are adopted, and the air leakage coefficient is less than 2%. The cleaning method is especially effective and prolongs the service life of the filter bag.
• Stable and easy to maintain:The quality of the key parts of the air box pulse bag dust collector is very reliable, the degree of automation is high, the work is stable, and the daily maintenance management is relatively simple.

Working Principle

When working, the dust-containing gas enters the ash hopper from the inlet air duct, the coarse dust particles directly fall into the bottom of the ash hopper, the fine dust particles enter the middle and lower box with the airflow turning point, the dust accumulation is attached to the outer surface of the filter bag, the filtered gas enters the upper box to the clean gas collection tube - exhaust air duct, and is discharged to the atmosphere by the exhaust fan. The cleaning process is to cut off the clean air outlet duct of the chamber first, so that the cloth bag of the chamber is in a state of no air flow through (separate chamber stop air cleaning). Then the pulse valve is opened and the compressed air is used to pulse the ash cleaning. The closing time of the cut-off valve is enough to ensure that the dust removed from the filter bag after the injection is settled to the ash hopper, avoiding the phenomenon that the dust is separated from the surface of the filter bag and then attached to the surface of the adjacent filter bag with the air flow, so that the filter bag is cleaned thoroughly. The exhaust valve, pulse valve and ash discharge valve are fully controlled by programmable pulse controller.

Question&Answer

Q:What is the reason for the big shaking of the raw material mill?

A:The shaking of the raw material mill is relatively large, and the main reason is generally that the motor is unstable or not enough. Or it is not put right, there is some bias and the machine motor is not a line. This can easily cause shaking or vibration, you can check to see if the concentric is on a line. And whether the fastening screws are loose and so on.
