Electrostatic Dust Collector

The working principle of the electrostatic dust collector is to use the high voltage electric field to ionize the flue gas. The dust charge in the air flow is separated from the air flow 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 of different geometries and is called a collecting electrode. The performance of an electrostatic precipitator is affected by three factors, the nature of the dust, the configuration of the equipment, and the flow rate of the flue gas. The specific resistance of dust is an index for evaluating conductivity, and it has a direct effect on the dust removal efficiency. The specific resistance is too low, dust particles are difficult to maintain on the dust collecting electrode, causing it to return to the air flow. The specific resistance is too high, and the dust particles that reach the dust collection electrode are not easily released. A voltage gradient between the dust layers can cause partial breakdown and discharge. These conditions will result in a drop in dust removal efficiency. The basic principle of electrostatic precipitators is to use electric power to trap dust from the fumes, which mainly includes the following four interrelated physical processes:
(1) The ionization of gas.
(2) The charge of dust.
(3) Charged dust moves to the electrode.
(4) Charged dust collection.
The most important motive of the company's products is to separate the particles and quality dust from the industrial exhaust gas, turning waste into treasure to be recycled. As the dust collection system manufacturer, main all types of dirt elimination equipment and accessories production: including long bag pulse dirt collector, gas box and stand-alone pulse dirt collector, electrostatic precipitator, electric powered auxiliary tar, etc. Warmly welcome forbusiness negotiations!

The Electromagnetic Valve 2019

Electromagnetic pulse valves (also known as diaphragm valves) are compressed air "switches" for pulse bag filter dust cleaning systems. By the control of the output signal of the pulse jet control instrument, the filter bag is cleaned by one row (chamber), so that the resistance of the filter is kept within the set range, so as to ensure the processing capacity and dust collection efficiency of the filter. DMF-Z electromagnetic pulse valve  is a right-angle valve, and the angle between the inlet and outlet is 90 degrees, which is suitable for the installation connection between the airbag and the dust blower tube. The air flow is unobstructed and it can provide the required clear air pulse. DMF-ZM electromagnetic pulse valve is the same as the "Z" series of the right-angle valve, suitable for airbag and dust collector spray pipe installation connection, the import and export of the two ends with a fixed nut for installation so that installation and us

Electrostatic Dust Precipitator

  1. Introduction of electrostatic dust precipitators   The power supply of the electrostatic precipitator consists of a control box, a step-up transformer and a rectifier. The output voltage of the power supply also has a great influence on the dust removal efficiency. Therefore, the operating voltage of the electrostatic precipitator must be maintained at 40-75kV or even above 100kV.   2. Basic structure of electrostatic dust precipitators   The electrostatic dust precipitators  are composed of two parts: one part is the main system of the electrostatic precipitator; the other part is the power supply device that provides high-voltage direct current and the low-voltage automatic control system. The high-voltage power supply system supplies power to the step-up transformer, and the dust collector of the dust collector is grounded. The low voltage electric control system is used to control the temperature of the electromagnetic vibrating hammer, the ash discharging electrode, the ash c

Ash Discharge Valve

The opening and closing part of the ash discharge valve  electric plug valve is a gate plate, and the direction of movement of the gate plate is perpendicular to the direction of the fluid. The electric plug valve can only be fully opened and fully closed and cannot be adjusted or throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valves form a wedge, and the wedge angle varies with the valve parameters. Principle: There is a round opening of a diameter on the gate, and the opening and closing of the gate makes the round opening on the gate to completely separate from and match with the diameter. Electric three-way valves are used for air conditioning, thermal ventilation, heat treatment in heat treatment plants, and industrial fluid control. Air-conditioning, heating, ventilation, domestic hot water and other civil systems and chemical, petroleum and metallurgical and fluid automation. Our dust collection syste
