Pulse bag dust collector is mainly a device that uses bag-shaped filter elements made of fabric to capture solid particles in dust-containing gas. The emergence of new filter materials and automatic dust cleaning methods has made this dust removal equipment, which has a history of more than 100 years, become increasingly perfect and widely used in modern industry. Botou Keming Environmental Protection Equipment Co., Ltd. will introduce to you the classification of single-machine bag dust collectors. According to the national standards for bag dust collector classification and specification performance expression methods, bag dust collectors are divided into five categories. The dust cleaning method is the main symbol of the classification of pulse bag dust collector
. Mechanical vibration type: a bag dust collector that uses a mechanical device (including manual, electromagnetic or pneumatic device) to vibrate the filter bag to clean the dust, and has a suitable gap There are two types of bag dust collectors: non-divided chamber structure for working and divided chamber structure suitable for continuous operation.
.Divided chamber backflush type: A bag dust collector that adopts a divided chamber structure and uses valves to switch the air flow chamber by chamber. Under the action of the reverse air flow, the filter bag is forced to shrink or bulge to clean the dust.
3. Nozzle back-flushing type: a bag dust collector that uses a high-pressure fan or compressor to provide back-flushing airflow, and carries out back-flushing through the moving nozzle, causing the filter bag to deform, shake, and penetrate the filter material to clean the dust ( All are non-divided structures).
. Combination of vibration and backflush: bag dust collector that uses mechanical vibration (including electromagnetic vibration or pneumatic vibration) and backflush (both are divided-chamber structures).
.Pulse injection type: Using compressed air as the cleaning power, the pulse injection mechanism is used to release the compressed air in an instant, inducing several times of secondary air to be injected into the filter bag at high speed, causing the filter bag to bulge sharply. Bag dust collector that cleans dust due to impact vibration and reverse airflow.
Summary of the main advantages of pulse bag dust collector
. The dust removal efficiency is high, generally above 10%, and the dust concentration in the gas at the outlet of the dust collector is within tens/3, which is suitable for sub-micron particle size The fine dust has higher classification efficiency.
. The air volume can be processed in a wide range, ranging from a small one to tens of thousands. It can be used to remove dust from flue gases in industrial furnaces and reduce the emission of atmospheric pollutants.
3. Simple structure, easy maintenance and operation.
.On the premise of ensuring the same high dust removal efficiency, the cost is lower than that of electrostatic precipitator.
.When using glass fiber, polytetrafluoroethylene, and other high temperature resistant filter materials, it can operate under high temperature conditions above ℃.
.Insensitive to the characteristics of dust and not affected by dust and electrical resistance.
