High voltage electrostatic precipitator overview:
The power supply of the high voltage electrostatic precipitator is composed 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 operation voltage of electrostatic precipitator should be kept at 40 75kV or more than 100kV.
Hebei Botou professional production base of high voltage electrostatic precipitator, product distribution throughout the country, high voltage electrostatic precipitator is a type of dust collector in Hebei high tech Environmental Protection Group Co. Ltd. the main sales; high voltage electrostatic precipitator has the advantages of reasonable design, high efficiency, safe and reliable use, wide application, maintenance and operation has the advantages of low cost more and more widely used. The electrostatic precipitator in our factory is a device for collecting dust from flue gas by electrostatic cleaning. It is an ideal equipment for purifying industrial waste gas.
High pressure purification mainly depends on two systems: discharge electrode and precipitating pole. Especially in large volume, special dust condition, wide spacing, horizontal electric dust remover shows the superiority of more and more, especially for general difficult to collect high resistive dust has unique advantages, so it is an ideal equipment for environmental protection.
High voltage electrostatic precipitator principle:
Dust gas from the top of the equipment inlet into the device, high-speed through cyclone separator, so that dust gas along the axis adjustment screw downward rotation, the use of centrifugal force to remove coarse particles of dust, effectively control the initial dust concentration into the electric field. Then, the gas under the hopper into the field, because the pipe section number under the hopper times greater than the cross-sectional area, according to the principle of constant torque, radial velocity and axial velocity decreases sharply from zero speed and heavy dust particle interface in the inner tube to settlement in the hopper, reducing the dust concentration into the low electric field. The concentration of dust containing gas by electric dust collector and condense in anode plate, after cleaning the dust and the dust collected by the air lock ash conveying device to go. The flue gas is ionized by the high voltage electric field, and the dust charge in the airflow is separated from the air flow under the action of the electric field. The negative electrode is made of metal wires of different sections, called discharge electrodes. The cathode is made of metal plates of different geometric shapes, called dust collecting electrodes. The performance of electrostatic precipitator is affected by three factors, such as dust properties, equipment structure and flue gas flow rate. The specific resistance of dust is an index to evaluate the conductivity, and it has a direct impact on the dust removal efficiency. When the specific resistance is too low, the dust particles are difficult to remain on the dust collecting electrode, resulting in the return flow. When the specific resistance is too high, the dust charge of the dust collecting electrode is not easy to release. The formation of voltage gradient between the dust layers will cause local breakdown and discharge phenomenon. These conditions will lead to the decrease of dust removal efficiency.
The characteristics of high voltage electrostatic precipitator:
Compared with other dedusting equipment, the high voltage electrostatic precipitator has less energy consumption and high dust removal efficiency, which is suitable for removing 0.01&mdash, 50&mu, m dust in the flue gas, and can be used in occasions where the flue gas temperature is high and the pressure is large. Practice shows that the greater the amount of flue gas treatment, the more economical the investment and operating cost of using electrostatic precipitator. The collection type high voltage electrostatic precipitator is a new type of dust removal equipment. The utility model has the advantages of reasonable design, compact structure, high dust removal efficiency, strong anti condensation ability, safe and reliable use, etc..
The structure of high voltage electrostatic precipitator:
1. electrostatic precipitator adopts steel shell, compact structure, convenient installation and maintenance, on one side of the shell and the ash bucket are equipped with the access door, so that workers in the installation and maintenance of internal, hopper part of the casing is provided with a spoiler, top beam and electric field two are arranged outside the windshield, to prevent the entrance to exit by bypassing the electric field gas containing dust and reduce dust removal efficiency. The shell of each column are respectively arranged on the fixed support and the movable support, to eliminate the casing heat stress. It is suitable for outdoor installation. The top of the shell has two layers of steel plate cover. One layer contacting with the smoke is the inner cover, which acts as the sealing electric field. The top layer is the outer cover to prevent the rain and snow from protecting the equipment. The insulation layer is installed on the outside of the equipment, and the insulation layer is made of heat preservation cotton and colored steel plate.
2. cathode (corona pole) and resonance rapping device: the corona line of electrostatic precipitator series uses knot like barbed wire, which has good discharge effect and intensity. The first electric field corona frame consists of four hangers suspended on the upper cone insulation electric porcelain bushing. The irregular deformation caused by heating will not affect its polar spacing, but also has enough mechanical strength and withstand voltage performance. Cathode rapping equipment according to the size of the top or side respectively around the rotary arm shaking mechanism, the rotating shaft charged so the ceramic shaft insulation, ceramic shaft through a universal joint shaft is connected with the rotation of the reducer motor drive, the vibration mechanism, reliable performance, it can avoid the vibration from the lifting type the phenomenon of clamping mechanism is easy to play.
The 3. anode (precipitation pole) device and vibration: anode steel rolled into “ C ” plate type, it has a certain strength, and can expand freely without causing the stress. The two time flying and can overcome the dust, the anode vibration are used around the side arm rotary vibration the mechanism, decelaration motor drive, has the advantages of small size, compact structure, convenient maintenance and installation has the advantages of stable and reliable.
Four. the electrostatic precipitator thermal insulation device: electrostatic precipitator to prevent surface condensation caused by electrical breakdown, porcelain bushing cathode ceramic shaft and hanging frame is provided with a heat preservation pipe and insulator insulation room configuration electric heaters and thermocouples, temperature control, using electric heating and steam heating for dew point temperature requirements of the users the ash bucket, to prevent condensation and clogging.
5. electrostatic precipitator air distribution device; as the dust gas evenly into the field, in the dust remover is provided with one to three days into the air distribution plate and a guide plate in a pair of on-demand, diversion according to airflow simulation experiments and field test results set hanging, hanging in the multi orifice hole position. Practice has proved that this form has a good uniform effect and not easy to plug holes and other advantages.
