Description

Technical Field

[0001] The utility model relates to the technical field of high-efficiency bag dust collectors for industrial waste gas, in particular to a high-efficiency bag dust collector for industrial waste gas. Background Art

[0002] In the process of industrial production, industrial waste gas will be generated. Before the industrial waste gas is discharged, the dust particles inside the waste gas need to be filtered through a dust collector to reduce the pollution to the environment. However, the existing industrial waste gas high-efficiency bag dust collector still has certain defects when used, such as;

[0003] For example, a high-efficiency bag dust collector with publication number CN206103544U adopts a bag with an inverted cone structure, so that dust on the bag is easy to fall off and not easy to accumulate. The bag is easy to install and can be replaced as needed. The combination of the ultrasonic generator and the ultrasonic transducer can emit ultrasonic waves, which can penetrate into the filter material to break up the dust particles squeezed or wrapped by the filter material fibers, thereby minimizing the clogging of the bag, extending the service life of the bag, and reducing the maintenance cost of the entire dust collector. The design of the sound-absorbing layer can also greatly reduce the noise pollution generated by the dust collector.

[0004] However, this high-efficiency bag dust collector still has the following disadvantages in actual use:

[0005] The cleaning operation is performed by emitting ultrasonic waves through an ultrasonic generator. The overall equipment cost is high, which increases the equipment investment cost, and the overall operation and maintenance are relatively complicated. In addition, only preliminary filtration is performed through cloth bags, so there is still a certain amount of fine particles and microparticles emitted, which not only pollutes the environment, but also reduces the efficiency of dust removal.

[0006] In response to the above problems, it is urgent to carry out innovative design based on the original industrial waste gas high-efficiency bag dust collector. Therefore, we proposed that the industrial waste gas high-efficiency bag dust collector can solve the above problems well. Utility Model Content
