DMC grain bag dust collector environmental protection and energy saving professional production
The grain bag dust removal equipment is a new type of pulse dust collector improved on the basis of the bag dust collector. It combines the advantages of various pulse jet dust collectors for reverse blowing in the compartment, and overcomes the shortcomings of insufficient cleaning intensity of the compartment and uneven distribution of inlet and outlet air. Expanded the scope of application.
Grain dust removal equipment is when the dusty gas enters the dust collector from the air inlet, it first encounters the inclined plate and baffle in the middle of the air inlet and outlet, and the airflow turns to flow into the ash hopper. At the same time, the airflow speed slows down. Due to inertia, coarse particles in the gas are caused. The dust flows directly into the ash hopper. It plays a role of pre-collecting dust. The airflow entering the ash hopper is then folded upwards and passes through the filter bag with a metal skeleton inside. The dust is trapped on the outer surface of the filter bag. The air outlet is discharged, and the dust-laden gas is purified through the filter bag. As time increases, more and more dust accumulates on the filter bag, which increases the resistance of the filter bag, resulting in a gradual decrease in the processing air volume. For normal work, it must be controlled The resistance is within a certain range (140-170 mm water column). Once the range is exceeded, the filter bag must be cleaned. When cleaning the dust, the pulse controller will trigger each control valve in sequence to open the pulse valve, and the compressed air in the air bag will be blown by the injection pipe. Each hole passes through the venturi tube to each corresponding filter bag, and the filter bag instantly expands rapidly, so that the dust accumulated on the surface of the filter bag falls off, and the filter bag returns to its original state. The cleaned dust falls into the ash hopper and is discharged from the body through the ash discharge system. As a result, the dust accumulated on the filter bag is periodically pulsed to clean the dust, so that the purified gas can pass through normally, and the operation of the dust removal system is ensured.
