The performance of electrostatic precipitator is affected by three factors, including 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. If the specific resistance is too low, it is difficult for dust particles to remain on the dust collecting electrode, causing them to return to the airflow. If the specific resistance is too high, the charge of the dust particles reaching the dust collecting electrode will not be easily released, and the voltage gradient formed between the dust layers will cause local breakdown and discharge phenomena.
The power supply of the electrostatic precipitator consists of a control box step-up transformer and a rectifier. The voltage output by the power supply also has a great influence on the dust removal efficiency. Therefore, the operating voltage of the electrostatic precipitator needs to be maintained at one or more.
Compared with other dust removal equipment, electrostatic precipitators consume less energy and have high dust removal efficiency. They are suitable for removing dust in flue gas, and can be used in situations where the flue gas temperature is high and the pressure is high. Practice shows that the greater the amount of flue gas treated, the more economical the investment and operating costs of using an electrostatic precipitator are.
A type of gas dust removal method. Dust-containing gases are electrically separated when passing through a high-voltage electrostatic field. After the dust particles combine with negative ions and become negatively charged, they tend to be discharged and deposited on the anode surface. It is used to purify gas or recover useful dust particles in industries such as metallurgy and chemistry. A dust collection method that uses an electrostatic field to ionize gas so that dust particles are charged and adsorbed to electrodes. In the strong electric field, air molecules are ionized into positive ions and electrons. When the electrons run toward the positive electrode, they encounter dust particles, which cause the dust particles to be negatively charged and adsorbed to the positive electrode for collection. It is often used in factories and power stations that use coal as fuel to collect coal ash and dust in the flue gas. In metallurgy, it is used to collect oxides of tin, zinc, lead, aluminum, etc.
Jufeng Environmental Protection Company mainly selects different dust removal equipment and waste gas treatment equipment for various working conditions. Types of dust removal equipment include: cyclone dust collector, bag dust collector, wet dust collector, water bath dust collector, etc. Among them, bag dust collectors are also called bag dust collectors and dry dust collectors. They are also divided into online pulse dust cleaning bag dust collectors and offline dust cleaning bag dust collectors. In terms of design, bag dust collectors are divided into ordinary bag dust collectors and high-temperature bag dust collectors. Anti-static bag dust collector, wet dust collector, and dust collector, desulfurization tower wet dust collector, etc. are also named according to their functions and usage. Exhaust gas treatment equipment includes dust removal and desulfurization tower exhaust gas adsorption towers. Exhaust gas adsorption tower is also called activated carbon adsorber. Each type of environmental protection equipment has various series and different designs for different working conditions. The company can choose different treatment methods and environmental protection equipment for users based on their actual working conditions and requirements, and provide a complete set of dust removal and waste gas treatment services from on-site surveying and mapping system design, manufacturing, installation, commissioning and after-sales service.
