Electrostatic precipitator

Electrostatic precipitator the anode made from different geometric shapes of metal plate, called dust collecting electrode. The performance of electrostatic precipitator dust properties, equipment structure and the influence of three factors such as flue gas flow rate. Dust resistivity is the conductivity of the evaluation index, it has a direct effect on dust removal efficiency. Low resistivity, dust particles was difficult to remain on the dust collector electrode, thus cause to return to the airflow. Than high resistance to the dust motes in the electrode charge is not easy to release, in the voltage gradient between the dust layer can produce local breakdown and discharge phenomenon. These conditions will cause the loss of dust removal efficiency. The power of the electrostatic precipitator is made up of control box, step-up transformer and rectifier. The power supply output voltage has a great influence on the dust removal efficiency is also. Therefore, electrostatic precipitator operating voltage to keep more than 40 a 75 kv and 100 kv.

Basic introduction to
The working principle of electrostatic precipitator [1] is the use of high voltage electric field ionization in the flue gas, air flow in the dust charged under the effect of electric field and flow separation. Anode made from different cross section shape of metal wire, discharge electrode.

The power of the electrostatic precipitator is made up of control box, step-up transformer and rectifier. The power supply output voltage has a great influence on the dust removal efficiency is also. Therefore, electrostatic precipitator operating voltage to keep more than 40 a 75 kv and 100 kv.

Electrostatic precipitator compared with other dust removal equipment, less energy consumption, high dust removal efficiency, and is applicable to 0 in a flue gas can be removed. 01-50 microns of dust, and can be used in the occasion of high flue gas temperature and pressure. Practice shows that the greater the processing of smoke gas, the use of electrostatic precipitator in the investment and operation cost the economy.

Wide spacing between the horizontal electrostatic precipitator technologies

An overview of the

HHD type electric precipitator is wide spacing the company introduce and draw lessons from foreign advanced technology, summarizes 30 years of experience in design, manufacturing and application, combining with the characteristics of Chinese industry industrial furnace flue gas condition, in order to meet the increasingly stringent emissions requirements and the WTO rule of market research and development of scientific research. The result has been widely used in metallurgy, electric power, cement and other industries. Deeply trusted by the customers, have strong ability of market competition.

Best wide spacing and plate special configuration

Electrostatic precipitator electrostatic precipitator

Makes the electric field intensity distribution, the plate current is more uniform and into the speed can be increased by 1.3 times, make the dust catcher than resistance expanded to 1-10 of 14 Ω - 10 cm, especially suitable for the fluidized bed boiler, new dry process cement rotary kiln, grate cooler, sintering waste gas dust recovery ratio of resistance, slow or eliminate the phenomenon of back corona.

A whole new RS corona line of domestic initiation

Maximum length can reach 15 meters, has a dizzy low voltage, corona current density is big, strong rigidity, never broken, has the ability to resist high temperature, thermal change, combined with excellent way at the top of the vibrating effect. According to the size of the dust concentration configuration corresponding corona line density, which can adapt to high dust concentration of dust collecting, maximum allowable inlet concentration of up to 1000 g/Nm 3.

Corona pole at the top of the strong shaking
Because the discharge electrode system adopting vibration at the top of the design, and break the routine to creatively USES asymmetric suspension design, each electric field and using computer software to optimize the design, the environmental equipment company shell in dust collecting area of the same situation, a decline in the overall length of electric dust collector for 3 to 5 meters, a 15% reduction in weight.

High insulation system

To prevent condensation of high voltage insulation materials by electric dust collector creepage, adopt the regenerative double pneumatic roof design, using the latest PTC, PTS materials, electrical heating insulation casing at the bottom of the hyperbolic inverse blow clean design, completely eliminate the porcelain bushing, common troubles of the condensation creepage and convenient maintenance, maintenance, replacement.

High matching L - C system

High pressure control can use DSC system control, PC operation, low voltage control adopts PLC control, touch screen operation in Chinese. High voltage power supply dc power supply, constant current and high impedance matching HHD ontology by electric dust collector. Can produce high dust removal efficiency, the ratio of high to overcome resistance, dealing with a high concentration of superior features.
