The working principle of the single pulse dust collector produced by Hebei Beijing Chuang Environmental Protection Equipment Co., Ltd. is as follows:

The dusty gas enters the expanded ash hopper of the XMC pulse jet bag filter for pre dust collection. It is evenly distributed between each filter bag through the guide plate, and the dust is retained on the outer surface of the filter bag to ensure that the equipment resistance does not exceed 1200Pa. High pressure gas is sprayed through an electromagnetic valve, causing compressed air (0.5~0.7MPa) inside the air bag to be blown out through the nozzle holes (called primary air) and induced by the Venturi tube to enter the filter bag. The surrounding air (called secondary air), which is several times the primary air, rapidly expands in an instant and shakes off dust with the opposite direction of the airflow, achieving the purpose of cleaning. Use a microcomputer automatic control device to adjust the cleaning cycle and pulse spraying time according to the dust, so that the dust collector operates within the range of the mouth.

The single machine pulse dust collector produced by Hebei Chuangyi Environmental Protection Equipment Co., Ltd. combines the advantages of various pulse jet dust collectors with chamber back blowing, overcomes the disadvantages of insufficient chamber dust cleaning intensity and uneven distribution of inlet and outlet air, and expands the application range.

The structure of a single pulse dust collector has its own characteristics, which improve dust collection efficiency, adaptability, and extend the service life of filter bags. Through production practice, the equipment operates stably, requires minimal maintenance, and has a wide range of combinations, receiving high praise from users.

The single machine pulse dust collector adopts the technology of high-pressure (0.5~0.4MPa) high flow pulse valve to blow and clean the dust filter bags one by one, which can collect a large amount of high concentration (1300g/m3n) dust (particles of 5 μ m, with a content of over 370%).

The single pulse dust collector produced by Hebei Chuangyi Environmental Protection Equipment Co., Ltd. can be widely used in the dust and smoke collection system of asphalt mixing plants such as crushing, grinding, drying machines, furnaces, etc. The material of the dust collector filter bag is generally polyester needle punched felt, which allows continuous use temperature ≤ 120 ℃. If the filter bag uses Metas high-temperature needle punched felt, its allowable use temperature can reach 204 ℃.

Single machine pulse dust collectors are widely used for dust control in cement plants, and are also widely used in the deep processing of non-metallic mineral fines. They have good application prospects in industries such as power, chemical, metallurgy, and steel.

Single machine pulse dust collector refers to the method of removing dust attached to the filter medium (bag or filter cartridge) by blowing compressed air; According to the size of a single pulse dust collector, there may be several sets of pulse valves controlled by a pulse controller or PLC. Each set of pulse valves is opened to remove dust from the bag or filter cartridge it controls, while the other bags or filter cartridges work normally. After a period of time, the next set of pulse valves is opened to clean the next part of the dust collector, which consists of ash hopper, upper box, middle box, lower box, etc. The upper, middle, and lower boxes are divided into compartments. During operation, dusty gas enters the ash hopper through the air inlet duct. Coarse dust particles directly fall into the bottom of the ash hopper, while fine dust particles enter the middle and lower boxes upwards with the turning of the airflow. Dust accumulates on the outer surface of the filter bag, and the filtered gas enters the upper box to the clean gas collection pipe exhaust duct, and is discharged to the atmosphere through the exhaust fan. The dust cleaning process involves first cutting off the clean air outlet duct of the room, so that the bag in the room is in a state of no airflow passing through (stopping the air and cleaning the dust in each room). Then, the pulse valve is opened and compressed air is used for pulse blowing to clean the dust. The shut-off valve is closed for a sufficient time for the dust peeled off from the filter bag to settle in the ash hopper after spraying, avoiding the phenomenon of dust adhering to the adjacent filter bag surface with the airflow after leaving the filter bag surface. The filter bag is cleaned, and the exhaust valve, pulse valve, and ash discharge valve are fully automatically controlled by a programmable controller. The dusty gas enters through the air inlet, and when passing through the ash hopper, some large particles of dust in the gas are separated by inertia and gravity, and directly fall into the bottom of the ash hopper. The dusty gas enters the filter bag filtration area of the middle box after passing through the ash hopper. The gas passes through the filter bag, and the dust is trapped on the outer surface of the filter bag. The purified gas enters the upper box through the filter bag opening and is then discharged through the air outlet.
