    What is the "three-state" cleaning method?

    When using two-state dust cleaning, due to the short suction time of the crawler (10-20s), the dust shaken from the lower part of the port bag near the ash bucket can still fall into the ash bucket, and when the length of the filter bag is large, the filter The dust falling off the upper part of the bag has no time to enter the ash hopper, the suction time is over, and it is brought to the filter bag by the subsequent filtering airflow, which produces the so-called "resorption". In order to prevent this phenomenon, a "sedimentation" process was added after "swelling" and "suckback" (sucking), that is, the three states of "swelling-suckback-settling" are used. This is the so-called "three-state" cleaning Grey law.

    According to the degree of cleaning, there are two forms of "three-state" cleaning: concentrated natural settlement and dispersed natural settlement.

    (1) Concentrated natural settlement

    This kind of dust removal system is that after two-state dust removal, the filter bag is concentrated for a period of time to allow it to settle naturally. Natural settlement is to close the exhaust (or air inlet) and air outlet for reverse blow at the same time, so that there is no air flow in the filter bag to achieve the stationary state of the filter bag, thereby creating a natural settlement condition for the dust falling in the filter bag.

    (2) Dispersed natural settlement

    This ash cleaning system is to arrange a period of rest time between each suction and inflation of the filter bag, so that the dust that shakes off the inside of the filter bag may naturally settle.

    The time required for natural sedimentation is related to the length of the filter bag and the nature of the dust. Generally, the longer the filter bag is, the lighter the density of the dust is, and the longer it takes to settle naturally.

    Various cleaning procedures are realized by the adjustment of the time relay. Through the control of the time relay, the anti-air blowing switching valve can be operated according to the pre-arranged cleaning program to perform the anti-air blowing cleaning.

    Maintenance of bag filter:

    1. Always check the operation of control valves, pulse valves and timers.

    The failure of the rubber diaphragm of the pulse valve is a common failure of the bag filter, which directly affects the dust removal effect. This equipment belongs to the external filter type, and the bag contains a skeleton. It is necessary to check whether the parts holding the filter bag are loose and the tension of the filter bag is appropriate. Whether the support frame is smooth to prevent abrasion of the filter bag. For cleaning, compressed air is used. Therefore, it is required to remove oil mist and water droplets, and the oil-water separator bi must be cleaned frequently to prevent the failure of the movement mechanism and the blockage of the filter bag.

    2. Whether the air volume and pressure and temperature of each test point are consistent with the design.

    3. The installation condition of the filter bag, whether there are bag dropping, loosening and abrasion after use, can be judged by visual inspection of the chimney emission after operation.

    4.Prevent condensation

    During use, it is necessary to prevent the gas from cooling in the bag room to below the lu point, especially when using a bag filter under negative pressure. Because the shell often has air leaking in, the gas temperature of the bag chamber is lower than the lu point, the filter bag will be damp, so that the dust is not loosely attached to the filter bag, and the fabric holes are blocked, causing Dust removal fails, causing the pressure drop of the dust collector to be too large to continue operation, and some paste bags cannot be removed.

    To prevent dew condensation, the temperature of the gas in the dust collector and its system must be kept at 25 to 35 ° C higher than its lu point (such as the lu point temperature of a kiln mill is 58 ° C, and the operating temperature should be above 90 ° C). ) To the good use of baozheng filter bags.

    What is the cohesiveness of dust? How does this property affect dust removal?

    Adhesiveness refers to the phenomenon of adhesion between dust frontiers or between particles and the surface of objects. The cause of stickiness is due to the presence of adhesion. The forces that produce adhesion in a gaseous medium are mainly van der Waals forces (ie, molecular gravity), electrostatic attraction, and capillary attraction.

    Adhesion of dust is a common phenomenon. It has both positive and negative aspects in practical applications. For example, if there is no adhesion, the dust falling on the ground will not be able to adhere to the ground, and will be continuously brought back to the air by the airflow, which will cause the dust concentration in the air to be high.

    Adhesion of dust also occurs in the dust removal device. Due to the existence of adhesion, the collision of dust will lead to the aggregation of dust particles. This effect will be beneficial to the capture of dust in various dust collectors, and this effect will appear in electric dust collectors and bag dust collectors. As prominent. However, in dust-containing air ducts and air purification equipment, it is necessary to prevent dust from sticking to the wall of the device, so as not to block the pipes and equipment.

    There are many factors that affect dust adhesion. In general, the particle size of the dust is very small, the more irregular the shape, the rougher the surface, the higher the moisture content, and the greater the charge, the more likely it is to cause adhesion. The degree of adhesion is also related to the surrounding medium. For example, the adhesion of dust in liquid medium is much weaker than in gas.
