this is technical data for parts of our ESP
Product Overview:The high-pressure electrostatic precipitator of SLDW Horizontal our newly developed dust products, good corrosion resistance, all parts in contact with corrosive gases are corrosion-resistant materials, the distribution of positive and negative plates using the latest technology, to improve the corona electric field, current density, and better capture the dust, it is widely used in electric power, metallurgy, chemical industry, building materials, light industry and other exhaust gas purification and recycling of waste.
The electrostatic precipitator is the use of the electrostatic force (Coulomb force), the dust in the gas or liquid droplets separated dust removal equipment, also called ESP, electrostatic precipitator. The electrostatic precipitator has been widely used in the smelting, cement, gas, power station boilers, sulfuric acid, paper and other industries.
The electrostatic precipitator its distinguishing feature is: almost all kinds of dust, smoke, etc., until the tiny particles have high collection efficiency; Even if the high-temperature, high-pressure gas can also be applied; resistance of the device is low compared with other precipitator ( 100 ~ 300Pa), low energy consumption; maintenance and overhaul is not complicated.
Second, the product features:
The electrostatic precipitator is composed by two parts of the the precipitator body and the power supply apparatus. Precipitator body including part of the discharge electrode, dust collection electrode, air distribution device, cleaning agencies, insulation device and shell.
1, single-zone ESP can be divided into the following types:
1) cleaning methods can be divided into wet electrostatic precipitator and dry electrostatic precipitator. Wet electrostatic precipitator using a spray, spray and overflow, water film is formed on the dust collection pole will adhere to the very surface of the dust particles away. The dry ESP vibration, etc., so that the accumulation of dust particles in the dust collecting on the polar surface off and fall into the ash bucket are excluded.
2) according to the direction of air flow, can be divided into vertical and horizontal electrostatic precipitators. Vertical ESP is generally made of tubular, bottom-up flow airflow, often operating under positive pressure. Horizontal electrostatic precipitators the airflow horizontal flow, high separation efficiency, easy maintenance, industrial-like horizontal ESP.
3) According to the dust collection can be divided into the very form of the tube and plate electrostatic precipitator. Tubular electrostatic precipitator is a safety in the center of the cylindrical tube into the electrode, and the circular tube inner wall to become the surface of the dust collection electrode, and the commonly used multi-row tube disposed in parallel arrangement. Plate electrostatic precipitator is installed between a series of parallel channels discharge electrode.
2, single electrostatic precipitator (grade)
In the single-zone precipitators, the chargeability of the particles and the dust collecting process in the same area, that is, the corona electrode and the dust collecting electrode in the same area.
3, dual-zone (level) precipitator
Particle charge and sedimentation dust collection in the dual zone electrostatic precipitator in the two regions, respectively, and are equipped with a set of electrodes in the first region is the dust particles charged in the second region, are equipped with another set of electrodes to make dust particles sedimentation dust collection. And more used in the air conditioning system.
Electrostatic precipitator works:
Electrostatic precipitator is the use of high-voltage electric field the flue gas to ionize charged dust in the air flow in the electric field and the flow separation. , Called the discharge electrode, a negative electrode is made by the different cross-sectional shape of the metal wires. The positive electrode is made of a different geometric shape of the metal plate, called the collecting electrode.
Electrostatic precipitator performance by the three factors of the dust characteristics, device structure and the flue gas flow rate. The specific resistance of dust is to evaluate the conductivity indicators, and its removal efficiency has a direct impact. The specific resistance is too low, dust is difficult to maintain on the collecting electrode, resulting in its return to the stream. Specific resistance is too high to reach the dust charge of collecting electrode is difficult to release, in the voltage gradient is formed between the dust layer will produce a partial breakdown and discharge phenomenon. These conditions will result in the removal efficiency decreased.
The electrostatic precipitators power control box, a step-up transformer and rectifier. The power supply output voltage level of the dedusting efficiency is also greatly affected. Therefore, the electrostatic precipitator operating voltage required to maintain more than 40 75kV even 100kV.
