High-voltage direct current decomposing dust wide-pitch electrostatic precipitator

The wide-pitch electrostatic precipitator is a kind of dust collector. The device uses high-voltage direct current to charge the dust particles in the dust-containing gas. Under the action of the electric field force, it is deposited on the surface of the sedimentation pole and then vibrated. The role of force causes the flakes to fall into the device, so that the flue gas passing through the electrostatic precipitator can be purified to meet environmental emission standards. It is an ideal equipment for industrial waste gas purification such as thermal power generation, metallurgy and non-ferrous metals. Based on years of production experience, we do not draw on advanced technology at home and abroad. Production of dust collection equipment for coal-fired power plants.

Installation of wide-pitch electrostatic precipitator:

1. Before the installation of the equipment, the size of the civil engineering foundation should be checked. If there is any discrepancy, the support should be installed on the basic table and leveled with the spirit level.

2. Unpack and check according to the equipment list. Correct the parts that have been deformed by lifting and long-term stacking before installation. Sampling inspection of major components (such as plate, corona wire corona pole frame), manufacturing deviation should exceed the design requirements should be corrected, if it can not be corrected, it should be scrapped.

3. All parts of the discharge electrode and sedimentation system are coated with special paint in the factory. If you can not buy kerosene and carbon black seasoning instead.

4, the transmission parts cleaning, refueling and other references (mechanical equipment installation and acceptance specifications).

Features of wide-pitch electrostatic precipitator:

1 can effectively capture high specific resistance soot. The wide-space anti-corona phenomenon is reduced, and at the same time, due to the large electric wind speed near the corona wire, the smoke is not easily bonded, and the electric corona lock-up phenomenon is not easily generated.

2 can capture smoke. The wide-pitch electrostatic precipitator can increase the operating voltage, accelerate the coagulation of soot, increase the particle size of soot, and increase the speed of soot driving, which is conducive to the collection of soot.

3 reduce power consumption. Although the corona electrode line current of the wide-pitch electrostatic precipitator increases, the number of corona electrodes decreases, so the total current decreases, and the total power also decreases.

4 save investment. As the pole pitch increases, the number of corona electrodes decreases and the weight of the dust collector decreases. However, for the pole pitch of 400~500mm, there is little or no increase in the cost of increasing the voltage.

5 easy to repair and install. Generally, the installation error of the electrostatic precipitator is extremely strict. The installation error of the electrostatic precipitator with a pole distance of 400~500mm can be slightly relaxed, and the wide-pole electrostatic precipitator can easily change the corona line.

6 Some applicable conditions. If the dust content of the flue gas is large, the spark voltage is lowered, and the space charge effect of the soot is strengthened to reduce the charge stability. In practice, a combination of wide and narrow pole pitch can be adopted, that is, the front electric field adopts a regular pitch, and the rear electric field adopts a wide pitch.

Wide-pitch electrostatic precipitators are widely used in industrial waste gas purification such as thermal power generation, metallurgy and non-ferrous metals.
