Description

Industrial dust electrostatic filter device

technical field

The utility model relates to a filter device in the field of environmental protection, in particular to an electrostatic filter device for industrial dust. the

Background technique

Dust refers to solid particles that can be suspended in the air. The dust produced in industrial production is called industrial dust. If industrial dust is not controlled, it will destroy the working environment, endanger the health of workers and damage machinery and equipment, and pollute the atmosphere. the

With the continuous expansion of industrial production scale, the types and quantities of industrial dust are also increasing. At the same time, after the formation of many industrial dusts, the surface can often absorb other gaseous or liquid harmful substances and become the carrier of other harmful substances. Industrial dust is one of the main occupational disease hazard factors that pollute the working environment and seriously endangers the health of workers. At present, there is no specific treatment for the harm caused by dust to humans, especially pneumoconiosis. Therefore, it is very important to prevent dust hazards and strengthen the control of industrial dust. the

Utility model content

The purpose of the utility model is to solve the deficiencies of the prior art and provide an industrial dust electrostatic filter device with simple structure, good control effect and convenient use and maintenance.

An electrostatic filter device for industrial dust, including a corona area and a dust collection area composed of a bracket, a front baffle and a rear baffle, the corona area includes a tungsten wire partition, a tungsten wire mounting plate, a tungsten wire, an insulating block , the tungsten wire mounting plate is installed on the bracket through an insulating block, a plurality of tungsten wires are installed on the tungsten wire mounting plate, and the adjacent tungsten wires are separated by a tungsten wire partition connected to the bracket Open into a single flue gas channel, the dust collection area includes positive aluminum plates, negative aluminum plates, spacers and screw rods, the positive aluminum plates and negative aluminum plates are fixed on the screw rods at intervals through spacers, and the screw rods are installed on the front baffle between the board and the tailgate. the

With the above scheme, in the utility model, fine particles enter the corona area of the device along with the air flow. Since the electrodes of the device are connected with the electrode shrapnel at the end of the high-voltage power supply wire, the corona electrode of the device (that is, the tungsten wire) ) emits a high voltage of about 8000 volts, under the action of a high voltage electric field, the gas passing through the vicinity of the corona electrode is ionized, generating a large number of free electrons and positive ions, these free electrons and positive ions are opposite to the polarity under the action of the electric field During the movement, it collides with gas molecules to ionize them and generate more free electrons. These free electrons and positive ions come into contact with dust particles during the movement to form dust charges. In the dust collection area of this device, due to the action of the electric field, the dust charge is adsorbed on the aluminum plate, so as to achieve the purpose of dust removal. the

To sum up, the utility model—the electrostatic filter device for industrial dust has the advantages of simple structure, good treatment effect, no secondary pollution, etc., and is suitable for industrial dust treatment. the

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described. the

As shown in Figures 1 and 2, an industrial dust electrostatic filter device includes a corona area and a dust collection area composed of a bracket 3, a front baffle 2 and a rear baffle 12, and the corona area includes a tungsten wire partition 8. Tungsten wire mounting plate 9, tungsten wire 10, insulating block 11, the tungsten wire mounting plate 9 is installed on the support through the insulating block 11, and a plurality of tungsten wires 10 are installed on the tungsten wire mounting plate 9, The adjacent tungsten wires 10 are separated into a single flue gas channel by the tungsten wire separator 8 connected with the bracket, and the dust collection area includes positive aluminum plate 4, negative aluminum plate 5, spacer ring 6 and screw rod 7. The positive aluminum plate 4 and the negative aluminum plate 5 are fixed on the screw rod 7 at intervals through spacers 6, and the screw rod 7 is installed between the front baffle plate and the rear baffle plate. the

When in use: fine particles enter the corona area of the device with the airflow (the corona area is the area where the tungsten wire 10 is located). Since the electrode 1 of the device is connected to the electrode shrapnel at the end of the high-voltage power wire, the device is in normal operation. A high-voltage electricity of about 8000 volts is released from the corona electrode. Under the action of the high-voltage electric field, the gas passing through the vicinity of the corona electrode is ionized to generate a large number of free electrons and positive ions. These free electrons and positive ions flow toward the electrode under the action of the electric field. During the movement, it collides with gas molecules to ionize them and generate more free electrons. These free electrons and positive ions come into contact with dust particles during the movement to form dust charges. In the dust collection area of this device, due to the action of the electric field, the dust charge is adsorbed on the aluminum plate, so as to achieve the purpose of dust removal. the
