LMS series offline dust cleaning pulse bag filter

The LMS offline dust cleaning pulse bag filter solves the problems of dust reattachment and loss of control that exist in conventional pulse bag filters, greatly improving the dust cleaning effect of filter bags, thereby increasing filtration speed, saving dust cleaning energy consumption, and extending the life of filter bags. The LMS offline dust cleaning pulse bag filter is particularly suitable for air purification of lightweight, fine-grained, and viscous dust. Divided into three series: large, medium, and small.

The LMS offline dust cleaning pulse bag filter solves the problem of "dust reattachment and loss of control" that exists in conventional pulse bag filters, greatly improving the dust cleaning effect of filter bags, thereby increasing filtration speed, saving dust cleaning energy consumption, and extending the life of filter bags. The LMS offline dust cleaning pulse bag filter is particularly suitable for air purification of lightweight, fine-grained, and viscous dust. Divided into three series: large, medium, and small.

People know that LMS offline dust cleaning pulse bag filter has excellent dust collection effect and extremely high dust removal efficiency in high concentration dust working conditions, and meets certain environmental requirements for export dust concentration. However, during our use, we often encounter some problems.

Reasons for bag damage in LMS offline dust cleaning pulse bag filter:

Through the process of sampling and testing the LMS offline dust cleaning pulse bag filter bag, the results showed that except for the damaged part, the air permeability, blasting strength, and fracture strength of other parts were very normal. At the same time, it was found that the damaged parts of the dust removal bag of the LMS offline cleaning pulse bag filter were almost entirely located 20-40cm away from the bag mouth, and the damage started from the inside. The main cause should be related to the blowback system. One is that the nozzle of the blowback system is not aligned, causing the blowback to deviate; On the other hand, the pressure of the compressed air blown back is too high, which causes damage to the bag of the LMS offline dust cleaning pulse bag filter.

Solution for LMS offline dust cleaning pulse bag filter:

The compressed air pressure of the reverse blowing air is controlled between 0.25 and 0.35 MPa, which can clean the dust on the bag of the LMS offline dust cleaning pulse bag filter. If the pressure is too high, it will affect the service life of the bag. Adjustments can be made by observing changes in the pressure difference between the inlet and outlet of the dust collector to keep the pressure difference within the required control range. The renovation of the LMS offline dust cleaning pulse bag filter spraying system is costly and has a long applicable period, which cannot be completed within the normal maintenance period. After research, it has been decided to add a protective sheath inside the bag of the LMS offline dust cleaning pulse bag filter. This method is simple and easy to operate, and the cost is relatively low. Adding a sheath inside the LMS offline dust cleaning pulse bag filter bag is much easier, simpler, and more cost-effective than modifying the spray system, making it a trustworthy product for people.

Product Features:

l. The LMS offline dust cleaning pulse bag filter is particularly suitable for air purification of lightweight, fine-grained, and viscous dust.

2. LMS offline dust cleaning pulse bag filter is divided into three series: large, medium, and small:

(1) Large series (outdoor type) LDML-I type

Filter area: 2160-5760m2

Processing air volume: 259200-691200m3/h LDML-II type

Filter area: 2880-7680m2

Processing air volume: 345600-921600m3/h Type I has offline dust cleaning function, while Type II has both offline dust cleaning and offline maintenance functions.

(2) Medium Series (Outdoor Type) LDMM Type

Filter area: 225-900m2

Processing air volume: 33750-135000m3/h

(3) Small series (indoor type) LDMS type

Filter area: 50-200m2

Processing air volume: 7500-30000m3/h

If LMS offline dust cleaning pulse bag filter users have special requirements, they can design the layout according to their needs. The specifications, models, and external dimensions of the series of dust collectors are shown in the attached drawings and tables.

3. The LMS offline dust cleaning pulse bag filter adopts a submerged pulse valve, with a small negative force in the flow channel and a gas source pressure ranging from the conventional 0.5MPa to 0.3MPa

4. Due to the offline spraying and cleaning of LMS pulse bag filter, the cleaning cycle has been extended from the conventional 3-5 minutes to 20-30 minutes, resulting in a reduction in cleaning energy consumption. The compressed air consumption is only about one tenth of that of the conventional type. At the same time, the fatigue wear of the filter bag and pulse valve membrane of LMS offline cleaning pulse bag filter is correspondingly reduced, thereby doubling the service life of the filter bag and valve membrane.

5. The LMS offline dust cleaning pulse bag filter bag adopts a spring expansion ring at the bag mouth, which has good sealing performance and is firm and reliable.

6. Adopting the upper LMS offline dust cleaning pulse bag filter bag extraction method, when changing bags, after extracting the skeleton, the dirty bags are put into the lower ash door of the box and removed through the inlet hole, improving the bag replacement operation strip

7. The layout of the import and export collection pipes is compact, with low airflow resistance.
