  • cement plant PPC Dust cleaning principle of air box pulse bag filter

      PPC Air box pulse bag filter There are several filter bag rooms in the filter, and the ash cleaning control of each chamber is an off-line ash cleaning mode under separate control, PPC There are many places in the design of the dust remover, which makes the use efficiency of the dust collector high and the service life is long.

    one When the dust containing gas enters the bag chamber, it will first touch the baffle plate, and the dust containing gas will move into the ash hopper along the direction of the baffle, and the larger particles will directly fall into the ash hopper under the action of gravity to pre collect dust and reduce the load of the bag.

    two In the process of ash cleaning, the off-line ash cleaning shall be carried out in each compartment in turn. During the dust cleaning, other chambers will not be affected and continue to work, which has no impact on the overall dust removal effect.

    three During ash cleaning, the air flow in the box chamber is controlled by the cylinder, and the compressed air is shared with the electromagnetic pulse valve, so the cost is reduced and the operation is simple.

    four The control during ash cleaning is PLC Control, to achieve automatic continuous control of ash cleaning, do not need to consider the control. After setting the program, the system will carry out continuous ash cleaning one by one according to the set time or pressure, making the operation simple.

    five Only one electromagnetic pulse valve is needed to control the dust cleaning of the box chamber. During the dust cleaning, the cloth bags in a box room will be cleaned at the same time. At this time, only one electromagnetic pulse valve is needed to solve the problem, which reduces the production cost and operation cost.

    PPC The off-line dust cleaning mode adopted by the air box pulse bag filter makes the dust cleaning efficiency of the dust collector high .

    Gas box pulse dust remover series products are based on the patented product technology, in order to expand the scope of use, to meet the needs of more users in the dust treatment capacity, high concentration.

    The main features of the product are as follows:

    one For the key components that affect the main performance, such as pulse valve and imported parts, the service life of diaphragm is longer than that of vulnerable parts one hundred Ten thousand times, continuous operation can guarantee more than four years.

    two One pulse valve needs to blow one chamber at the same time thirty-two sixty-four ninety-six one hundred and twenty-eight Four specifications series), so more common high pressure pulse dust collector one Valve injection six Strip bag can reduce the number of pulse valves six twenty Times.

    three A pre dust collecting mechanism is designed, which not only overcomes the direct erosion and wear of filter bags, but also can deal with high concentration, allowing the inlet concentration up to 1000g/Nm3

    four The ash cleaning mechanism of pulse valve is controlled by single chip microcomputer. It also has three control modes: fixed resistance, fixed time or manual control. This product is widely used in building materials industry, such as crushing, packing, silo top, grate and dust collecting system of various mills. It can also be used in metallurgical industry and foundry industry.

    Structure:

    The dust remover is composed of upper box, middle box, lower box and ash hopper, ash discharge device, ladder platform and pulse dust cleaning device.

    The upper box includes a small lifting cover, an air storage bag and a pulse valve.

    The middle box includes a filter bag, a cage bone and an air inlet and exhaust pipe.

    The lower box and ash hopper include column, ash hopper and manhole.

    The ash discharging device includes an ash unloading valve.

    The ladder platform includes vertical ladder and railing.

    The pulse ash cleaning device includes three control modes of fixed resistance, fixed advance or manual operation.

    working principle:

    Under the action of the main fan of the system, the dust containing gas enters the pre dust chamber of the dust collector from the air inlet of the dust remover, and the dust laden air flow turns to flow into the ash hopper under the impact of the baffle plate. At the same time, the flow rate slows down. Under the action of inertia and self weight of dust, the coarse dust directly falls into the ash hopper and is discharged from the ash discharge mechanism, playing the role of pre dust collection; other light and fine dust are adsorbed on the outer surface of the filter bag along with the gas flow direction, and the filtered clean gas enters the upper box through the filter bag and is collected and discharged from the air duct. For small specifications thirty-two The air inlet of bag series products is set on the ash hopper with the same principle.

    With the continuous filtration condition, more and more dust accumulated on the outer surface of the filter bag, which will increase the operation resistance of the equipment. In order to ensure the normal operation of the system, the resistance of the dust collector should be maintained within the limit one thousand and four hundred 1700Pa Within the range, when the limit is exceeded, the pulse shall automatically send out the command of fixed resistance or fixed advance or manual to clear the ash.
