Pulse dust collector
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.

Cyclone dust collector is a dust removal device that uses the centrifugal force generated by the rotating airflow to separate dust particles from the combined airflow. It has advantages of simple structure, small size, does not need special auxiliary equipment, low cost, medium resistance, no moving parts in the device, easy operation and maintenance etc. The cleaning principle is inertia (using centrifugal force) and gravity. Cyclone dust collectors are the most popular of all types of dust removal equipment and have been used in all industries.
The dust gas enters the cyclone through the tangential upward air inlet pipe, and moves spirally from top to bottom to the bottom of the cone, form a descending outer rotating dust-containing airflow. The centrifugal force generated during the strong rotation throws the dust particles towards the wall of the cyclone, once the dust particles contact the wall of the device, they lose their inertial force and fall along the wall by the momentum of the inlet velocity and their own gravity into the ash collecting bucket for discharge. After the rotating descending air reaches the bottom of the cone, turns up along the axis of the dust collector. A rising internal swirling air flow is formed and discharged from the exhaust pipe of the dust collector
