As a widely used dust collector, some customers report that they will always encounter problems such as substandard discharge. The reason for this problem may be due to the fast filtration speed of the filter cartridge, the short cleaning cycle of the filter cartridge, and the injection of compressed air. Caused by high pressure and reduced dust loadability.
At present, the standard of environmental protection testing is based on the emission concentration, which restricts the environmental protection of enterprises that produce exhaust gas pollutants: for example, if the national emission standard is 30mg/m3. But our local emission standard is lower, maybe 10mg/m3, so can we meet the standard?
At this time, the particle size of the dust must be considered. If the particle size of the dust is above 3 microns, it is no problem to control the emission concentration within the standard, but if the particle size of the dust particles in the exhaust gas is very fine, even below 0.3 microns, Then it is more difficult to control the emission standard within the standard range.
If the discharge of the filter cartridge dust collector exceeds the standard after cleaning the filter cartridge, it is necessary to detect whether the cleaning compressed air pressure is too large. Insufficient dust layer. The injected compressed air pressure is too high, and the dust load capacity is reduced.
When setting the pulse cleaning time of the filter cartridge dust collector, it should be ensured that the equipment works normally under the corresponding pressure, and the pulse cleaning cycle should be extended to ensure that the initial dust is not easy to fall off. If the initial dust layer is insufficient, the cleaning time can be extended. If the differential pressure control is adopted, the set value of the inlet and outlet pressure of the filter cartridge dust collector can be increased.
The reduction of the dust load of the filter cartridge dust collector may come from the reduction of productivity, or it may be caused by the inspection and adjustment of the control system of the filter cartridge dust collector. The treatment method: you may choose to use light load and slow starting to lift or use pre-coated dust. way to deal with.
In addition, it is recommended to replace the filter cartridge in the filter cartridge dust collector every 2 years, and check and check all components before installation. If there are problems such as deformation, repairs should be carried out before installation.
