Unpowered automatic-adjustment cloth bag dust removal device

Abstract

The invention provides an unpowered automatic adjustment cloth bag dust removal device, which comprises an outer frame, a cloth bag dust removal ventilation pipeline arranged on the outer frame and aplurality of groups of cloth bag dust removers arranged on the two sides of the cloth bag dust removal ventilation pipeline in parallel. One side of the second box body is communicated with the clothbag dust removal ventilation pipeline through a first ventilation opening. An adjusting valve is arranged on the first ventilation opening. The adjusting valve comprises an outer frame fixedly connected with the ventilation opening and an adjusting plate hinged to one side of the outer frame. In the direction from the air inlet to the air outlet, the weights of the adjusting plates are sequentially decreased progressively. According to the device, the damping of the adjusting plate close to the air inlet can be enhanced, the air inflow of each second box body is balanced, the ash removal effect is remarkably improved, and the service life of an internal cloth bag is remarkably prolonged.

Description

Technical field [0001] The invention relates to the field of environmental protection and dust removal, and more specifically to a non-power automatic adjustment cloth bag dust removal device. Background technique [0002] Bag dust collectors are also called bag dust collectors and bag dust collectors. With the improvement of modern research and development technology, bag dust collectors have become the most widely used dust removal equipment. [0003] But at present, the structure of the bag filter has the following shortcomings: [0004] 1. When multiple bag filters work side by side, the air intake of each bag filter is different, resulting in a low utilization rate of the bag filter far away from the air inlet, and the dust removal effect of the bag filter near the air inlet cannot be achieved. Guaranteed and easily damaged; [0005] 2. The cross-sectional area of ​​the air inlet of each chamber of the bag filter is small, the airflow entering the chamber is unevenly distributed...

AI Technical Summary

Problems solved by technology

[0004] 1. When multiple baghouses work side by side, the air intake of each baghouse is different, resulting in a low utilization rate of the baghouse far away from the air inlet, and the dust removal effect of the baghouse near the air inlet cannot be achieved. Guaranteed, and vulnerable to damage;

[0005] 2. The cross-sectional area of ​​the air inlet of each chamber of the bag-type dust collector is small, and the airflow entering the chamber is unevenly distributed, and the uneven field flow will lead to low dust removal efficiency of the bag, and even the bag with a heavy load will burst directly;

[0006] 3. The uneven distribution of the airflow will also cause the large particles in the flue gas to be unable to settle and separate effectively;

[0007] 4. Due to the uneven distribution of air flow, the utilization rate of the bag at the edge is not high. Generally, when replacing the bag, all the bags are replaced directly at the same time. When the central bag needs to be replaced, the peripheral bag has not yet reached the replacement standard, resulting in increased operation. maintenance cost
