The advantages of a central dust collector for sale are many. The structure is relatively simple, for some factories that need to regularly replace or clean the bag dust collector, the single pulse dust collector has a simple structure, the installation is more simple, the maintenance is also easy, and the price is favorable, so it is a good choice for some small factory enterprises, and the cost performance is also a better dust collector. Secondly, the dust removal effect is good. About can absorb fine dust, tens of meters of cubic environment can be easily vacuum work. It can be directly hung around some small machinery, so it is a good choice for small equipment working environments.

Pulse bag dust collectors also have disadvantages. At first, for dust with a good water content, the effect of a single pulse dust collector will be greatly reduced. And with the increase of water content, the inside of the bag will slowly deposit, which is not convenient to clean, so the service life will be shorter. In addition, there are relatively good requirements for temperature, too high temperature will make the bag can not support, reduce the use effect, so the use of pulse bag dust collector space to small and medium-sized dry environment.

The filter bag material of the pulse cloth bag dust collector is determined by the size and height of the dust removal gas according to its moisture content, temperature, acid and alkali and dust concentration. The filter bag material of LUP series filter type low-pressure pulse bag filter, when there is no acid, it needs to be determined according to the temperature of dust. At less than 130 ° C, choose 500-55 polyester material.

When more than 130℃ is less than 250℃, choose aramid Nomex needle felt, glass fiber needle felt or Flumas FMS high temperature filter material. If the fluorine content in the flue gas is relatively good, then the glass fiber material cannot be used. When the dust concentration is large, the anti-condensation filter and anti-wear filter are selected. These can be afraid of water,. If it is an acid-base gas and the temperature is less than 190 ° C, then Rvton polyphenylene sulfide is selected. Less than 240℃ gas temperature, can not require too high sex, should choose polyphthalimide material. If the dust is flammable and explosive gas, then choose polyester needle felt.

The compressed gas in the bag is mainly used as ash cleaning energy, so that the electromagnetic pulse valve forms a pulse airflow from the top of the bag to the bottom of the bag and shakes. The purpose is to shake the dust cake tied to the outside of the cloth bag into the dust bucket of the dust collector by pulse shaking. If the pressure or flow is insufficient and the air flow is too weak, the ash removal strength cannot reach the bottom of the filter bag of the power plant dust collector, and the dust cake cannot be peeled off to form local ash accumulation. Resulting in large equipment resistance, uneven load of filter material, shorten the service life of the cloth bag. On the other hand, if the ash removal force is too large, the fine particles that have penetrated into the surface of the filter material will be punched out of the surface, resulting in excessive friction with the dragon frame and the broken bag.

In the box design of the pulse bag dust collector, it is generally required that the height is more than one meter longer than the installed dust collector, which is conducive to air diffusion, reducing the impact on the dust bag, and improving the life of the bag and the dust removal rate. The dust bag base wood installed in the sinter batching dust removal device is flush with the upper edge of the ash hopper, and the cloth bag is replaced frequently. When making the upper box, the wall should be smooth (it is the inquiry between the warehouse roof, and the rain often flows away). The installation of the four-sided beam of the warehouse top cover should have sufficient strength to prevent the deformation and sinking of the four-sided beam, otherwise it will lead to the warehouse top cover is not tightly sealed and air leakage. This problem exists in the dust removal process of 50 ton steel converter, which leads to difficult maintenance. The plate in the box (the wicker between the upper box and the middle box) is one of the key accessories of the bag dust collector, which mainly plays the role of separating dust gas and fixing dust bags. When bidding, the positioning die technology should be adopted, the plate hole should be processed by CNC four-column stamping, the aperture deviation is ±0.1mm, the hole distance deviation is ±0.5mm, the flatness of the board is less than 2CP1000, the diagonal length deviation is less than 5mm, and the dust bag should be installed. To facilitate the air leakage caused by the corrosion deformation of the plate, the dust collector will be similar to the installation of the coke tank in the storage and transportation department of our factory. There has been a problem of corrosion deformation of the plate, producing smoke, and then replacing the plate to solve the smoking problem.

Since the advent of the central dust collector for sale in the 1950s, after external use, continuous improvement, in the purification of dust containing gas has made great development, due to ash cleaning, gas cloth ratio is large, so it has the characteristics of large air volume, small footprint, good purification rate, work, simple structure, small maintenance and so on. The dust removal rate can reach more than 90%. It is a mature and better dust removal equipment.
