Product Introduction

The working principle of an electrostatic precipitator is to use a high-voltage electric field to ionize the flue gas, and the charged dust in the airflow is separated from the airflow under the action of the electric field. The negative electrode is made of metal wires with different cross-sectional shapes and is called a discharge electrode.

The positive electrode is made of metal plates with different geometric shapes, called a dust collecting electrode. The performance of electrostatic precipitators is influenced by three factors: dust properties, equipment structure, and flue gas flow rate. The specific resistance of dust is an indicator for evaluating conductivity, which has a direct impact on dust removal efficiency. The specific resistance is too low, making it difficult for dust particles to remain on the dust collection electrode, resulting in their return to the airflow. If the specific resistance is too high, the dust particles that reach the dust collection electrode are not easily discharged, and a voltage gradient is formed between the dust layers, which can cause local breakdown and discharge phenomena. These situations will cause a decrease in dust removal efficiency.

Characteristic

Compared with other dust removal equipment, electrostatic precipitators consume less energy and are suitable for removing dust particles of 0.01-50 μ m from flue gas. They can also be used in situations where the flue gas temperature is high and the pressure is high. Practice has shown that the larger the amount of flue gas processed, the more economical the investment and operating costs of using electrostatic precipitators.

Wide spacing horizontal electrostatic precipitator technology

This achievement has been widely applied in industries such as metallurgy, power, and cement.

Wide spacing and special configuration of electrode plates

By making the electric field strength and plate current distribution uniform, the driving speed can be increased by 1.3 times, and the specific resistance range of captured dust can be expanded to 10 1-10 14 Ω - cm, which is particularly suitable for high specific resistance dust recovery from waste gases such as sulfide bed boilers, new cement dry rotary kilns, sintering machines, etc., to slow down or reverse corona phenomena.

Overall new RS corona wire

The length can reach 15 meters, with low corona voltage, high corona current density, strong rigidity, no damage, high temperature resistance and heat resistance. Combined with the top vibration method, it has good dust cleaning effect. According to the dust concentration, configure the corresponding corona wire density to adapt to high dust concentration dust collection, allowing the inlet concentration to reach 1000g/Nm3.

Top vibration of corona electrode

According to the dust cleaning theory, the top discharge electric vibration can be designed using either mechanical or electromagnetic methods.

Free suspension of yin and yang poles

Increase vibration acceleration

Small footprint and light weight

Due to the top vibration design of the discharge electrode system and the innovative use of asymmetric suspension design for each electric field, as well as the optimization design using the shell computer software of the environmental equipment company, the overall length of the electrostatic precipitator is reduced by 3-5 meters and the weight is reduced by 15% under the same total dust collection area.

High insulation system

To prevent the high-voltage insulation material of the electrostatic precipitator from condensing and creeping, the shell adopts a double-layer inflatable roof design with thermal storage, the electric heating uses PTC and PTS materials, and the bottom of the insulation sleeve adopts a hyperbolic back blowing cleaning design. This makes the ceramic sleeve prone to condensation and creeping faults, and the maintenance, upkeep, and replacement are extremely convenient.

Match L-C high system

High voltage control can be controlled by DSC system and operated by upper computer, while low voltage control can be controlled by PLC and operated by Chinese touch screen.   Can generate efficiency, overcome high specific resistance, and handle functions.
