LDMD long bag offline pulse dust collector is a long bag offline pulse dust collector technology and product with the level of the 1990s, which combines more than ten years of research technology experience and achievements, and integrates the current long bag offline pulse dust removal technology to introduce to users. It is a large-scale dust removal equipment with high air volume, good dust cleaning effect, high dust removal efficiency, reliable operation, easy maintenance, and small footprint. After entering the dust collector from the middle box, the dusty gas moves downwards and is filtered by a bag filter. The dust is trapped outside the filter bag, and the purified air is collected by the clean air box at the upper opening of the bag and discharged from the air outlet. After the dust collector filters the dusty gas for a certain period of time, the dust resistance on the outer surface of the filter bag increases. The cleaning time is determined according to the actual situation, and the control instrument sends a command signal. The lifting valve in the chamber begins to close, cutting off the filtered airflow, and then the pulse valve in the chamber opens to be greater than 0. 4MPa compressed air is flushed into the clean air chamber, causing dust on the filter bag. After this action is completed, the lift valve will reopen, allowing the chamber to resume filtering work; According to the above program, automatic and continuous cleaning of the filter bag is carried out, ensuring the cleaning effect of compressed air on the filter bag.

The technical characteristics of LDMD long bag offline pulse dust collector include:

1. Low pressure spraying technology: Considering the high concentration of smoke and dust generated by the combustion of power plant boilers, equipment resistance will increase rapidly, and the frequency of dust cleaning will be accelerated as a result. Using high-pressure spraying will have adverse effects on the service life of filter bags, and the dust layer attached to the filter bags will be washed away, which is not only unfavorable for dust to fall into the ash hopper by its own gravity, but also easy to cause secondary adsorption of dust.

We monitored the fly ash in the flue gas through a camera probe and found that it is relatively dry at the operating temperature. In addition, we have made the filter bag easy to clean, using lower pressure for cleaning. This not only achieves the ideal cleaning effect, but also shortens the time for dust to fall into the ash hopper. It can avoid secondary adsorption and shorten the service life of filter bags due to frequent dust cleaning.

2. Diversion technology: Electromagnetic pulse valve and filter bag are the core components of JDDM low-pressure pulse bag filter, and diversion is the core technology. Based on our company's design philosophy, we have taken a series of measures to ensure that the flue gas is evenly distributed to each bag, which not only ensures that the filter bag can bear the load evenly and extend its service life, but also reduces equipment resistance.
