laser dust collector in stock is a dry filter device. It is suitable for capturing fine, dry, non-fibrous dust. The dust bag is made of textile filter cloth or non-textile felt, and the filter effect of fiber fabric is used to filter the dust containing gas. We all know that the bag dust collector has the corresponding resistance when it runs, which mainly comes from the pipeline, elbow, inlet and outlet, dust bag, smoke pipe and so on. The resistance of the dust collector is directly related to the length of the pipeline, the number of elbows, the material of the cloth bag, and the filter resistance. The general operating resistance of laser dust collector in stock is between 1200-2000pa.

When setting the pulse cleaning cycle of a small laser dust collector in stock, it is better to ensure that the dust collector works under stable pressure and the set pulse cleaning cycle time is long, and the pulse cleaning time is better to ensure that the initial dust does not fall off and the set cleaning time is short. If the initial dust layer is insufficient, Can be extended cleaning cycle reward, if the use of differential pressure control, can improve the dust collector inlet and outlet pressure setting stability. If the excessive discharge of the dust collector occurs only after cleaning the filter bag, it is only necessary to check whether the pressure of the compressed air for pulse cleaning is too large. The load reduction of dust may come from the reduction of productivity, or is caused by the maintenance and adjustment of the control system of the dust collector, the solution: you can use the light load slowly start to lift the load or use the method of pre-coating dust to solve. Some studies have shown that: too high filtration speed, dust discharge rate will increase, too high filtration gas speed, will make the initial dust layer broken, and dust impact filter bag caused by excessive wear, if the cleaning bag is too high, easy to lead to loose filter bag fabric, these will make the dust collector emissions exceed the standard.

When running a single pulse bag filter, the state of the differential pressure system should be observed to see if there is a fault. The pressure difference value of the pressure difference system of the pulse single bag dust collector is accurately recorded. If the pressure difference is suddenly found in the recording process, it is necessary to check the filter bag to see whether there is blockage or dust compaction. At the same time, the ash cleaning system should be accurately checked to avoid excessive ash accumulation in the ash hopper. If there is a sharp drop during the recording process, it may be that the filter bag is damaged or is falling off.

laser dust collector in stock has the advantages of simple structure, low investment cost, simple operation, low technical requirements for management and maintenance. When the flue gas containing dust enters the middle and lower box by the inlet of the dust collector, the dust is adsorbed on the dust filter bag, and the gas enters the upper box through the Venturi tube through the filter bag, and is discharged from the outlet. With the accumulation of dust on the filter bag, the pressure loss of the filter bag gradually increases, and the pressure loss is fed back to the controller by the pressure gauge. The controller receives and issues instructions to trigger each pulse solenoid valve in sequence, so that the gas in the air bag is sprayed instantaneously from the holes of the spray pipe, and the pipe is sprayed into the corresponding filter bag. The filter bag does not expand slowly under the instantaneous reaction of the air flow, so that the dust accumulated on the surface of the filter bag falls off, and the filter bag can be recycled and reused. Field observation of a large number of damaged filter bags shows that the damaged parts of the filter bags are almost circular holes and long cracks. The test also showed that the undamaged part of the damaged filter bag and other filter bags in the filter unit were not significantly deformed, and the good residue rate was basically normal. This shows that the polymer fiber filter material does not have obvious cracking during use.

laser dust collector in stock The performance of filter cloth has a great influence on the dust removal rate and property of filter cloth. The filter material should have the following conditions: it can prevent dust from passing through, and the weft and weft holes are small, and the warp and weft themselves should be able to increase the area of the screen and reduce resistance. The fabric is long and elastic, can cover the holes and has a good degree; To promote the use of reverse air cleaning, the wool of the fabric is located on the side where the dust and air come into contact. The lower the filtration rate, the easier it is to form a dust layer with small particle size and large porosity, and the more dust particles can be collected. When the wind speed is too high, the filtration rate is reduced by increasing the penetration of dust particles into the filter material. Of course, penetration can also be overcome by choosing the right filter material. In addition, when the filtration speed changes within the range, it almost does not affect the dust removal rate of some filter media.
