The high-voltage electrostatic precipitator produced by Hebei Chuangyi Environmental Protection Equipment Co., Ltd. is a device that uses the principle of high-voltage electrostatics to purify dusty gases. It forms a high-voltage electrostatic field by adding high-voltage direct current to the anode and cathode. The gas ionizes under the action of the electric field force, producing a large number of electrons and ions. When the dusty gas enters the electric field, the dust particles combine with these electrons and ions to charge the dust particles. Under the action of electric field force, charged dust particles tend to have opposite electrical properties, and then release charges on the electricity and deposit on it. When the number of dust deposition islands increases, the dust falls into the ash hopper through the action of the vibration device, and the purified gas from which the dust particles are removed is discharged into the atmosphere through the electric field. The same dust can have significant changes in specific resistance under different meteorological conditions, humidity, and temperature. Therefore, a more effective method is to conduct actual measurements on the processed dust. Therefore, in the case of the total height of the cylinder, appropriately increasing the height of the conical cylinder part is beneficial for improving the dust removal efficiency. Generally, the height of the cylindrical part is 1.5 times its diameter, and when the height of the conical cylinder is 2.5 times the diameter of the cylindrical body, a relatively ideal dust removal efficiency can be obtained.

Instructions for using the high-voltage electrostatic precipitator produced by Hebei Beijing Chuang Environmental Protection Equipment Co., Ltd.:

a、 Specific resistance of dust: The specific resistance requirement for dust in this tubular electrostatic precipitator is 104-1012 ohms/cm.

b、 Electric field wind speed: The recommended operating condition for electric field wind speed is 0.5-1.6m/min; If the specific resistance of dust is high or low, a lower wind speed should be selected, but because the properties of gases are constantly changing.

c、 Inlet dust concentration: The standard requirement for the inlet of this equipment is generally not greater than 35g/m3. When the concentration is greater than 35g/m3, a design scheme can be adopted to solve the problem. For dust within this range, this series of electrostatic precipitators can be used. For dust outside the range, electrostatic precipitators are generally not considered and bag filters or high-voltage electrostatic precipitators can be used.

Technical parameters of CDG series high-voltage electrostatic precipitator:

1. Equipment types: mainly divided into vertical and horizontal types; Single room, double room; Wet operation, dry operation.

2. Dimensions (mm): Depending on the cross-sectional area and length of the electric field.

3. The ability to process exhaust gas (m3/h, Nm3/h): It is generally expressed in terms of the air volume processed under working conditions or standard conditions.

4. The equipment specifications are usually expressed as: LURGL: ZG/FT/NxZST/GA; The solution can be achieved by parallel operation of several high-voltage electrostatic precipitators. The air volume processed by parallel operation is the sum of the air volumes processed by each dust collector, and the resistance is only the resistance of the portion of air volume that a single dust collector is responsible for processing. However, parallel use is more complex to manufacture, so a smaller cylinder diameter should be selected appropriately. However, if the cylinder diameter is chosen too small, the wall and exhaust pipe will be too close, and particles will easily escape; The diameter of the cylinder is too small and can easily cause blockage, especially for viscous materials. When dealing with high air volume, the dust containing air volume is limited due to the small diameter of the cylinder; Domestic: WY-F-III.

5. Equipment pressure resistance (Pa): Designed according to the requirements of the process system. The chance of separating dust from the dusty airflow increases, but the total height of the cylinder increases. The radial velocity of the centripetal force in the outer vortex also increases the chance of some small dust entering the inner vortex, thereby reducing the dust removal efficiency.

6. The velocity of flue gas in the electric field (m/s) generally needs to be less than 1m/s. The total height of the cylinder is generally 4 times the diameter of the cylindrical body. For the conical cylinder part, due to its decreasing radius, the tangential velocity of the airflow continues to increase, and the distance for dust to reach the outer wall also decreases. The dust removal effect is better than that of the cylindrical part.

7. The flange size of the air inlet and outlet (mm): There are also many materials required, and the gas is easily blocked, which increases the resistance. Therefore, when used in parallel, the number of units should not be too many. The total height of the cylinder refers to the sum of the heights of the cylindrical and conical parts of the dust collector. Increasing the total height of the cylinder can increase the number of rotations of the airflow inside the dust collector, depending on the cross-sectional area of the electric field. According to the requirements of the process layout, there are several options for horizontal intake, upper intake, and lower intake. The commonly used form is horizontal intake, with a size to mouth ratio of 15:1.

8. Equipment resistance (Pa): generally<200Pa.

The high-voltage electrostatic precipitator produced by Hebei Chuangyi Environmental Protection Equipment Co., Ltd. is a commonly used dust collector. Although it may seem simple and can often follow the example, it often fails to collect dust. The key reason is the failure to control the golden ratio of cylinder diameter. The diameter of the cylindrical body is the basic size that constitutes a high-voltage electrostatic precipitator. The tangential velocity of a rotating airflow is inversely proportional to the centrifugal force generated by dust and the diameter of the cylinder. At the same tangential velocity, the smaller the diameter D of the cylinder, the smaller the radius of rotation of the airflow, and the greater the centrifugal force experienced by particles, making it easier for dust particles to be trapped.
