Large-scale wet electrostatic dust removal equipment
Large-scale wet electrostatic dust removal equipment is suitable for hot forging flue gas purification treatment, with continuous or intermittent flushing and dedusting ability, can handle high temperature and high concentration flue gas dust, viscous smoke dust, graphite dust, can also be used for VOCs front-end treatment, steel plant flue gas environmental protection Treatment, etc., can achieve centralized treatment of flue gas .
This purification equipment not only has high dust removal efficiency, small pressure loss, simple operation, and no secondary dust, but also can cool high-temperature gas and absorb harmful substances in the gas. It is suitable for the treatment of hydrophilic graphite dust with extremely small particle size. Compared with the traditional plate type wet electrostatic purification equipment or square and round tube type wet electrostatic purification equipment, the honeycomb tube type equipment has a larger dust collection area, under the same processing capacity, the volume is small, the material is less, and the investment cost is low .
Applicable occasions: hot forging, die casting, VOCs front end, steel mill, etc .;
Treatment air volume: 10 4～3 × 10 5 Nm ³ /h;
Dust collector type: tubular honeycomb type;
Purification efficiency: ≥95% ;
Peak voltage: 72 KV ;
Equipment resistance: 300~600 Pa ;
Cleaning cycle: ≥6 months.
The basic principle of wet electrostatic precipitator is the same as that of dry electrostatic precipitator. It uses the strong field strength generated by high-voltage electricity to ionize the gas around the corona pole, that is, to produce corona discharge, which generates a large number of ions in the electric field space. Collision with dust or water mist makes it charged, and because the specific resistance of water is relatively small, the combination of water mist and dust in the corona area can reduce the specific resistance of high specific resistance dust. In addition, at high DC voltage Under the action of the water mist, the charge is split and further atomized. Due to the relative movement of the dust and water mist moving with the airflow, the charged water mist can capture the dust particles through inertial collision, adsorption, condensation, and diffusion. The dust particles are subjected to electric field forces Is driven to reach the dust collecting plate, and is discharged with the water film evenly distributed on the surface of the plate.
