Pendant rebound bag type dust removal method and dust removal device

Abstract

The invention relates to the technical field of environment-friendly dust removers. The invention discloses a pendant rebound bag type dust removal method and a dust removal device. The device comprises a shell, an induced draft fan, an electric pull rod, a stop rod, a filter bag, a gravity weighting body and an ash bucket;, wherein a purified gas outlet is formed in one side of the shell, a dustygas inlet is formed in the other side of the shell, a gas filter bag is wrapped in the shell, a bag opening in the upper end of the gas filter bag is fixed on a pattern plate at the upper part in theshell, and a cross rod and a pull rod are arranged in the middle section of the filter bag; according to the invention, by means of the gravity and shape of the ball at the bottom of the filter bag,the internal space of the filter bag is expanded; a pulse type hard framework made of steel or plastic and the like is not used, so that friction between the filter bag and the hard framework is avoided, and an air compressor does not need to be additionally arranged; furthermore, huge power consumption and noise are avoided, and the defect that the filter bag is rapidly blocked due to large suction force is overcome; meanwhile, the occupied area is small, the treatment gas amount is large, the maintenance cost is low, and the operation cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of dust collectors, and in particular relates to a dust collector with high efficiency and long-lasting purification rate and a dust removal method. Background technique [0002] Today, as people become more and more aware of the protection of the atmospheric environment, the existing dust removal technology and equipment cannot maintain a lasting purification rate. The purification efficiency is very high in the first one or two years, and the inspections are qualified. Afterwards, the dust removal Efficiency will decrease year by year, which is a fact that the existing dust removal technology cannot change. [0003] Because the existing main dust removal methods have many disadvantages, the biggest disadvantage of the pulse filter bag dust removal technology is that due to the instantaneous expansion of the pulse and the friction between the hard frame and the filter bag, the filter bag will be damaged by ...

Problems solved by technology

[0002] Today, as people become more and more aware of the protection of the atmospheric environment, the existing dust removal technology and equipment cannot maintain a lasting purification rate. The purification efficiency is very high in the first one or two years, and the inspections are qualified. Afterwards, the dust removal The efficiency will decrease year by year, which is a fact that the existing dust removal technology cannot change

[0003] Because the existing main dust removal methods have many disadvantages, the biggest disadvantage of the pulse filter bag dust removal technology is that due to the instantaneous expansion of the pulse and the friction between the hard frame and the filter bag, the filter bag will be damaged by wire drawing, and the dusty gas will It will pollute the atmosphere directly, the loss of the filter bag is huge, the service life is very short, and the cost of dust removal operation is very high; the disadvantage of the electric dust removal technology is that the actual dust removal purification rate is lower than 99% of the bag dust collector, even for low-temperature electric dust removal, The purification rate at the beginning is only 95%, and the purification rate of electric dust removal will gradually decrease with the increase of use time, and the power consumption is also large. Equipment will gradually corrode, high maintenance costs and other disadvantages, so new dust removal technology is needed to control smog
