  • Design scheme for transformation of pulse bag filter of dryer in carbon plant

      Pulse bag filter Since it came into being in the 1950s, it has been widely used at home and abroad and continuously improved, and great development has been made in the purification of dust containing gas. Due to the advanced dust removal technology and the large increase of air cloth ratio, it has the characteristics of large air volume, small floor area, high purification efficiency, reliable work, simple structure and small maintenance amount. The dust removal efficiency can reach zero point nine nine above. It is a mature and perfect dust removal equipment.  

    Pulse bag filter is to make the dust gas pass through the fabric filter bag , Use high pressure air to blow dust on filter bag through pulse valve , A device that collects dust. The advantages of bag filter are : High purification efficiency , Stable performance , It is easy to operate , Strong adaptability , The recovered dust is easy to use. It is very important for the dust collector to operate normally , The operation of electrical control equipment is reliable. According to the design of dust remover and the equipment running on site for many years , Programmable control of dust removal equipment operation , It has the characteristics of compact structure, complete function, high reliability, easy operation and maintenance.

    Working principle of dust collector:

    negative pressure Pulse bag filter At the negative pressure end of the fan , The dust collector adopts the structure of lower air inlet and upper exhaust air external filter , There are separate bag chambers , When a bag filter chamber is used for ash cleaning , The pulse valve is controlled by the control mechanism , High pressure gas is ejected and a large amount of air is brought in to blow the dust on the filter bag , Make the dust fall into the ash hopper , Dust is removed by ash conveying system , Dust laden gas flows through the pores of filter material , The clean gas is discharged into the atmosphere through the exhaust pipe.

    Ash cleaning control process:

    The method of negative pressure suction was used to clean the dust in different rooms. During normal operation of dust collector , The dust containing gas enters the dust collector from the inlet short pipe on the ash hopper , The dust of coarse particles settles naturally in the ash hopper , Fine dust rises with the air flow into the filter bag , Due to the collision, screening, hook and intercept effect , Dust is trapped on the outer wall surface of the filter bag , The clean gas from the filter bag is discharged into the atmosphere through the exhaust pipe, fan and exhaust funnel. When the dust layer on the outer wall of the filter bag is gradually thickened , The resistance of the filter bag is also increased correspondingly , After reaching the specified value( 1960Pa Left and right) rear , That is to say, each room takes turns to clean the ash. Dust removal begins , First close the exhaust valve , The filter bag room is temporarily in a static state without air flow , At this time, the high-pressure gas injection valve starts , Blow the dust off the filter bag , Make the dust layer accumulated on the outer wall of the filter bag fall into the ash hopper. Because the quantity of high pressure gas ejected from pulse valve is limited by the pressure of compressed air , So the pulse valves in each chamber don't work together , Instead, one valve acts one valve at a time ,_ After the operation of the next pulse valve is completed , Open the vent valve , Return to normal filtering state , The next chamber will be cleaned.

    Pulse bag filter The structure includes the following parts:

    one Shell part: including clean room (or gas purification box, gas box), filter room, auxiliary room, diaphragm, maintenance door and shell structure. The clean room is equipped with lifting valve and flower plate, and the filter room is equipped with filter bag structure.

    two Ash hopper and ash discharging structure: according to different series and different dust concentration, ash hopper has screw conveyor, air conveying chute and ash unloading valve.

    three Inlet and outlet box: including inlet and outlet pipes and intermediate clapboard. The single row structure is arranged on one side of the shell, while the double row structure is arranged in the middle of the shell. The air inlet pipe and air outlet pipe are connected to the ash hopper clean room.

    four Pulse dust removal device: including pulse valve, air bag, lifting cylinder and electromagnetic valve.
