At present, a large number of domestic Vacuum Cleaner Constructor is used in large quantities of acupunctured felt materials, which belongs to deep filtration and rely on the dust particles that are cut on the filter material for filtering. The life of the dust collector is shortened and the operation is relatively difficult.

In addition, the price of Vacuum Cleaner Constructor is high, and the pressure fluctuations during operation and backwashing are relatively large. These factors have greatly limited the use of Vacuum Cleaner Constructor in industrial production. Surface filtering technology can solve the problems mentioned above. Surface filtering technology refers to the filtering technology that is not in the filter material, and all deposit in the filter surface.

The surface filtration mainly uses the film to filter the dust, rely on the filter of the film, and also use the dusty thin layer on the surface of the membrane surface. The pore diameter of the thin hole is very small, which can remove most of the dust particles on the surface of the membrane, and the process of completely qi is separated. Small than the separation of ordinary filter materials, the dust does not penetrate inside the fiber. The advantage is that when the bag starts to work, it can form a thin and thin layer of dust on the surface of the membrane, which can ensure higher dust removal efficiency and lower operating resistance.

Vacuum Cleaner Constructor can be widely used for the dust -controlling dust removal system such as ironmaking plants, steelmaking plants, refractory plants, casting plants, and power plants, and its use scope is very wide. When work in dust removal, it will also be affected by some factors. Among them, the efficiency factors affect the efficiency of the dust collector:

1. Selection of dust removal bags: Dust -dust bags should choose wear -resistant high -temperature material, including glass fiber cloth, NOMEX, needle felt, P84 needle felt, etc. Considering the wear resistance, high temperature resistance and cost of cloth bags, and the transformation, and the transformation of the cloth bags and other factors. The copper industry generally uses NOMEX acupuncture.

2. Temperature control: Generally, the temperature of the NOMEX bag to withstand the temperature is 200 degrees, so the import temperature of the processing facility should be controlled below 200 degrees. When the flue gas reaches the dust collector in a long tobacco pipe, the temperature can drop to 200 ° C to 200 ° C. In the following special circumstances, water cooling can be performed and a cooler is installed in the total cigarette pipe.

3. Fan selector: The fans are better than the ventilator.

4. Machinery dust removal is more convenient and clean than artificial dust removal, but the cost of dust removal is high. Most of the pulse removal method is used.

5. Wind leakage and resistance: Theoretically calculate Vacuum Cleaner Constructor dust removal efficiency of 99%, but the measured measurement cannot be achieved. It is mainly the effect of leakage and resistance. The lower the leakage rate, the better the dust removal effect. , Frequent filter bags to reduce resistance and improve the dust removal effect.

6. The dust cover should be as close as possible to the stove's head, making the dust easier to enter the cover, increase the amount of dust collection, and reduce the pollution of no tissue emissions.

7. Equipment maintenance: Instrument equipment and cloth bags are prone to damage to timely repair and replacement of cloth bags.

8. Pitching speed: At the speed of 1 ～ 3 m/s, the dust removal effect is good, and the general wind speed is controlled at 2 to 4 m/s.

9. Filtering area: The larger the filtration area, the higher the dust removal efficiency, but the cost will increase accordingly. Therefore, the air volume should be calculated in advance, and then the corresponding dust collector model should be selected.

10. Secondary dust removal: In front of the Vacuum Cleaner Constructor box, a sedimentation room is installed to form a secondary dust removal. The settlement room can remove some large particles of dust, reduce the temperature, and reduce the pressure of the dust collector.
