What is the working principle of a dust collector?
2023-11-18 06:18:30

Dust Collector is a common and efficient dust removal equipment, mainly used for centralized treatment and purification of dust in industrial production. It has the advantages of simple structure, stable operation, and high dust removal efficiency, and has been widely used in many industries. The working principle of this equipment mainly includes aspects such as device structure, working process, and ash cleaning method.

Firstly, let's understand the structure of the dust collector. The dust collector mainly consists of an air box, a filter bag room, a spraying system, and an ash cleaning device. The bellows is installed in the upper part of the dust collector for inhaling air and dust airflow. The filter bag room is the core part of the entire dust collector, with many cloth bags inside. When the dust airflow passes through the filter bag room, it will be intercepted on the filter bag, and the purified gas will be discharged through the air outlet. The blowing system is responsible for spraying pulse airflow, causing the dust on the filter bag to fall off and fall into the ash hopper. The dust removal device is used to remove dust from the ash hopper, ensuring that the dust collector maintains a good dust removal effect.

The working process of a dust collector can be roughly divided into several steps, such as filtering material, filtering, pulse blowing, and dust cleaning. Firstly, after the dust airflow enters the filter bag room, due to the decrease in air flow rate, the dust begins to sink and come into contact with the surface of the filter bag. Large particles of dust directly fall into the ash hopper, while smaller particles of dust are intercepted by the filter bag. As time passed, enough dust gradually accumulated on the surface of the filter bag.

Next, when the thickness of the dust layer reaches a certain level, the dust removal device begins to work. The pulse blowing system will spray high-pressure pulse airflow onto the surface of the filter bag, causing the dust on the filter bag to shake off through rapid expansion and contraction. Under the action of the blowing airflow, the dust on the filter bag will fall off in a pulsating manner and fall into the ash hopper. This process can be carried out either on one side or on both sides, ensuring the uniformity of the dust removal effect.

Finally, the dust removal device sends the dust from the ash hopper out of the dust collector for subsequent treatment. When cleaning the ash, methods such as mechanical vibration, gas flushing, or gas back blowing can be used to achieve this. These methods can effectively remove dust from the ash hopper and prevent it from entering the filter bag room again. In addition, to ensure the effectiveness of ash cleaning, the working cycle and cleaning time of the ash cleaning device can be adjusted according to actual needs.

Overall, the dust collector traps dust on the filter bag through the action of the filter bag, while the purified gas is discharged through the air outlet. Under the spraying effect of the pulse blowing system, the dust on the surface of the filter bag is detached and falls into the ash hopper. The dust removal device is responsible for removing dust from the ash hopper and ensuring the normal operation of the dust collector. In this way, the dust collector can efficiently filter and clean the dust generated in industrial production, purify the air, and ensure the cleanliness and hygiene of the production environment.
