When the dust removal equipment is in use, there are often some failures. Some failures can be resolved by themselves, and some failures require the dust removal equipment manufacturers to come to the door to resolve the failures. , Or if the dust removal equipment manufacturer comes to the door to solve it, it can do half the work with half the effort. So how to deal with the failure of the dust removal equipment?
How to troubleshoot the dust removal equipment is as follows:
First, the reason for the damage of the dust removal equipment bag
The first is that the nozzle of the backflush system is not correct, which constitutes the backflip deflection; the other is that the pressure of the backflush compressed air is too high.
： 进行喷吹体系改造，改造费用高、周期长，不能在正常的检修期间内完结。 1 : Transform the injection system. The cost of the transformation is high and the cycle is long. It cannot be completed within the normal maintenance period.
： 反吹风压缩空气压力操控在 0．25～0．35MPa之间，能够把布袋上的灰清掉即可，如压力过高则影响布袋的运用寿命。 2 : The pressure of the back blowing compressed air is controlled between 0.25 and 0.35 MPa, and the ash on the bag can be removed. If the pressure is too high, the service life of the bag will be affected. It can be adjusted after investigating the pressure difference between the inlet and outlet of the dust collector to make the pressure difference within the control requirements (planned pressure difference <1700Pa).
： 调整喷吹程序，把喷吹脉宽从 150ms调整为250ms，以减小喷吹的力度，削减布袋的磨损。 3 : Adjust the spraying program, and adjust the spraying pulse width from 150ms to 250ms to reduce the intensity of spraying and reduce the wear of the bag. Because it cannot be replaced under normal startup conditions, when the bag is severely damaged, it will not only cause the surrounding bag to accumulate and cannot be used normally. Together, it will also constitute an overdose of exhaust dust and pollute the environment. The cost of other bags is also higher. This treatment not only saves costs, maintains the normal operation of the equipment, extends the service life of the bag, but also maintains the environment well.
、除尘效果欠安 ,排放粉尘浓度超支，出口冒灰,粉尘排放量大,可从以下几个方面查找原因： Second , the dust removal effect is not safe , the discharge dust concentration is overrun, the outlet is ashing, and the dust emission is large. The reasons can be found from the following aspects:
： 新装的洁净滤袋孔隙较大 ,刚开始运用时粉尘经过率较高,没有到达最佳的过滤状况,粉尘排放量较大。 1 : The newly installed clean filter bag has large pores , and the dust passing rate is high at the beginning of use. It does not reach the optimal filtering condition, and the dust emission is large. With the progress of filtration, dust accumulates on the outer surface of the filter bag to form a dust layer, which reduces the pores on the outer surface of the filter bag, improves the dust removal power, and the effect of "dust filtration" can remove more than 99% of fine dust. Therefore, the determination of the dust removal power of the pulse bag dust removal equipment is more accurate after one month of continuous use.
： 2 : Check that the filter bag is installed correctly. ,依托缝制于滤袋口的弹性胀圈将滤袋嵌压在花板孔内,经过花板将中箱体尘气室与上箱体净气室严厉区别。 The general pulse bag type dust removal equipment relies on the elastic expansion ring sewn on the filter bag mouth to press the filter bag into the hole of the flower plate, and the medium box dust room is severely distinguished from the upper box clean room through the flower plate. If the elastic expansion ring at the mouth of the filter bag is not completely in close contact with the hole of the flower plate, and there is a gap, it will cause the air flow containing dust to directly enter the clean room, and the outlet of the exhaust tube will be dusty. You can check the condition of the device of the dust filter bag one by one, and find that the gap must be tightly sealed. During the installation of the pulse bag type dust removal equipment, the quality of the filter bag is one of the main points for supervision and inspection. The iron plant has improved and optimized the filter bag device: a ferrule is welded above each hole of the flower plate, the height of the ring is 30mm and is concentric with the hole of the flower plate. The ring is closely attached to the inner wall device of the ferrule, which not only ensures that the device of the filter bag is highly flat and sealed, but also makes the device of the filter bag easier to disassemble.

： 3 : Damage to the filter bag will cause the dust-containing air stream to be discharged directly, and the outlet of the exhaust pipe behind the dust collector will ash. ,能够选用以下办法断定破袋的方位:用手动操作方法逐一仓室进行清灰,每次关闭1个仓室的出气阀,留意调查排气筒出口,当有破袋的仓室中止过滤时,排气筒出口就不再冒灰,据此可断定哪个仓室呈现破袋。 Regarding the large-scale pulse bag dust removal equipment for off-line dust removal , the following methods can be used to determine the direction of the broken bag: Manually clean the dust one by one, and close the air outlet valve of one compartment at a time. When the filtering is stopped in the compartment with broken bags, the outlet of the exhaust cylinder will no longer be dusty. Based on this, it can be determined which compartment shows broken bags. If only a single filter bag is damaged and the hole of the flower plate is sealed with an iron cover, the discharged dust concentration can be guaranteed to be qualified. When it is necessary to replace the filter bag, it is advisable to replace one cut dust cloth bag of the same dust collector to ensure that each filter bag has equal resistance. If only a few filter bags can be replaced, the bag mouth of the new filter bag needs to be closed, buried in the dust removal ash for a few days, the resistance of the new filter bag is added, and the resistance of the new filter bag is close to the old filter bag.
： 关于进风通道与出风通道仅用隔板分隔的除尘器 ,须查看中心隔板是否焊接紧密。 4 : Regarding the dust collector in which the air inlet channel and the air outlet channel are separated by partitions only , check whether the center partition is welded tightly. If the center partition shows welding seams and gaps, the high-concentration dust near the inlet air will enter the air outlet channel, resulting in ash at the outlet of the exhaust pipe. Ensuring the welding quality of the central partition and completely separating the air inlet channel from the air outlet channel is another important point of quality inspection of the side of the dust collector manufacturing device.
