High voltage pulse dust collector

Institutional principles
The dust collector is divided into four parts: the upper box, the middle box, the lower box and the injection system. There is a flower board isolation between the upper box and the middle box, making the upper box a clean air chamber and the middle box It is a dust chamber with bags installed on the ceiling. When the dusty gas in the dust bin enters the dust air chamber of the middle box, the dust is blocked on the outside of the bag, and the filtered air enters the clean air chamber of the upper box and is then discharged into the atmosphere through the outlet.
As the operation continues, the dust attached to the bag accumulates more and more. The longer the time, the greater the resistance of the bag, the smaller the exhaust volume, which will affect the normal operation of the dust collector. For this reason, we designed a pulse reaction system. Dust blowing system. The pulse backflush cleaning system is controlled by a pulse controller. The dust on the outer surface of the bag is regularly cleaned. The dust cleaning is done round by round, so the normal operation of the dust collector is not affected during dust cleaning. The dust swept down by dust cleaning falls directly into the dust bin, and no special staff is required. The dust removal work of the dust collector.
According to the design requirements of the dust removal system, the dust collector must also be equipped with a fan to force the ash warehouse to exhaust and reduce the pressure in the ash warehouse, thereby ensuring the safety of the ash warehouse.

Working principle

The compressed air flow ejected from the blow hole attracts the surrounding air and sprays it into the venturi tube and then enters the bag. Due to the sudden expansion of the gas, the bag vibrates and the gas passes rapidly from the inside of the bag to the outside of the bag, causing the adhesion to the bag. The dust on the surface of the bag breaks away from the bag.

High voltage pulse dust collector

Main features

1.The dust removal efficiency is high, generally above 99%. The dust concentration in the gas at the outlet of the dust collector is within 10 mg/N㎡’, and it has a high classification efficiency for fine dust with sub-micron particle size.
2.The processing air volume range is wide, the small one is only a few m’ per minute, and the large one can reach tens of thousands of m’ per minute.
3.Simple structure, easy maintenance and operation.
4.On the premise of ensuring the same high dust removal efficiency, the cost is lower than that of the electrostatic precipitator.
5.When using high temperature resistant filter materials such as glass fiber and polytetrafluoroethylene, it can operate under high temperature conditions of 200~250℃.
6.Insensitive to the characteristics of dust and not affected by dust and resistance.

Components

Upper box: composed of a liftable cover and an air outlet;
Middle box: composed of flower board and filter bag device;
Lower box: composed of air inlet and ash hopper (TBLMY series only) Injection system: composed of pulse controller, solenoid valve, injection pipe air storage bag, etc.
Filter bag: filters dust and discharges clean gas.
Cage bone: fixes the filter bag and allows the filter bag to filter the largest area. Flower board: fixes the filter bag and keel, and divides the dust collector into two parts (i.e. upper box and middle box).
Flower board: fix the filter bag and keel, and divide the dust collector into two parts (i.e. upper box and middle box)
Blow pipe: There is a nozzle hole on the wall of the pipe, and the compressed air enters the bag through the nozzle hole. Centrifugal fan: discharges the filtered air into the atmosphere.
Air pipe: used to transport compressed air into the jet pipe
Solenoid valve: It is a switch that injects compressed air into the filter bag and is controlled by the output signal of the pulse meter.
Air storage bag: used to store compressed air source.
Pulse controller: used to control pulse injection time, pulse interval time and automatically control the injection sequence of each row of bags.
