Pulse dust collector adopts a cleaning method using pulse spraying. The interior contains multiple cylindrical high-temperature resistance filter bags, and the box is made by strict welding process. The inspection doors are sealed with plastic rubber, so it can ensure that the whole machine is tight and does not leak air. It has advantages of high efficiency, large processing air volume, long filter bag life, small maintenance workload, safe and reliable operation, etc. It is widely used in dust removal and purification of non-fibrous dust in various industrial and mining enterprises like metallurgical, construction, machinery, chemical, and mining etc. This product is mainly composed of a box body, air filter bags, ash hopper, gas pipe, pulse valves, a fan and a controller.
Dust-containing gas enters the interior of the dust collector from the air inlet. Due to the rapid expansion of the gas volume, some of the coarse dust particles fall into the ash bucket due to inertia or natural settlement, most of the remaining dust particles enter the bag chamber with the airflow. After filtering through the filter bag, the dust particles are retained on the outside of the filter bag. When the dust on the surface of the filter bag continues to increase, causing the equipment resistance to rise to the set value, the time relay (or differential pressure controller) outputs a signal and the program controller starts to work. The pulse valves are opened one by one, so that the compressed air is sprayed through the nozzle, so that the filter bag suddenly expands. Under the action of reverse airflow, the dust attached to the surface of the filter bag quickly leaves the filter bag and falls into the ash hopper (Or ash bin), the dust is discharged by the ash discharge valve, the purified gas enters the upper box from the inside of the filter bag, and then is discharged into the atmosphere through the valve plate hole and the air outlet, so as to achieve the purpose of dust removal.
The cyclone dust collector is designed for cleaning gases or liquids from suspended particles. The cleaning principle is inertial (using centrifugal force) and gravitational. Cyclone dust collectors constitute the most massive group among all types of dust collection equipment and are used in all industries.
Principle of operation
The principle of the counter-flow cyclone is as follows: a stream of dusty gas is introduced into the apparatus through the inlet pipe tangentially in the upper part. A rotating gas flow is formed in the apparatus, directed downward towards the conical part of the apparatus. Due to the inertial force (centrifugal force), dust particles are carried out of the stream and settle on the walls of the apparatus, then are captured by the secondary stream and enter the lower part, through the outlet into the dust collection bin. The dust-free gas stream then moves upwards and out of the cyclone through a coaxial exhaust pipe.
