Industrial wet electrostatic precipitator

Basic Info

Brand: yaoxian

Product Description

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

Working principle of electrostatic precipitator

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.

Advantages of electrostatic precipitator

1. Adequate dust collection area and suitable electric field wind speed;

2. Adopting 540mm same pole distance;

3. Adopting a reasonable extreme configuration form;

4. Adopting a uniquely designed inlet airflow distribution plate;

5. Establish effective mechanisms to reduce smoke and dust spillage;

6. Adopt reasonable vibration force and vibration speed to prevent the plates and wires from sticking to dust;

7. Ensure smooth operation of the ash hopper and ensure the normal functioning of the ash conveying system;

8. Adopting sealing technology to strictly control shell air leakage;

The electrostatic precipitator was successfully developed by Jiangyin Yaoxian Environmental Equipment Co., Ltd. It adopts a special tubular three electrode structure, which has a wider adaptability to capturing powder. At the same time, an appropriate pre charged electrode is added at the inlet, which can achieve high dust removal efficiency with a shorter electric field. The entire electric field is firm and reliable, and the price is relatively low. Easy to install, adjust, maintain and use, it is an ideal dust removal equipment for small and medium-sized enterprises.

Scope of use:

1. Industrial and heating coal-fired boilers, heavy oil fired boilers.

2. Building materials: dry and wet cement rotary kilns, mechanized shaft kilns, raw and clinker mills, raw material dryers, and cement packaging machines.

3. Nonferrous smelting: sintering of copper, lead, zinc, copper melting furnace, electric arc furnace, reflector furnace, etc.

4. Metallurgy: Iron ore sintering machines (head and tail), blast furnaces, open hearth furnaces, coke ovens, converters, electric arc furnaces, and refractory materials industries.
