Deduster inlet three-dimensional air distribution device

Abstract

The invention discloses a deduster inlet three-dimensional air distribution device. The device comprises a duster box provided with an air inlet and a smoke inlet pipe; the smoke inlet pipe is provided inside with an air distributor; one of the upper side edge and lower side edge of the air distributor aligns with one air inlet edge at the same side as the side edge, and the distance between the other side edge and one air inlet edge at the same side as the side edge is 0.30-0.35 time of the length of the air distributor. One of the left side edge and right side edge of the air distributor aligns with one air inlet edge at the same side as the side edge, and the distance between the other side edge and one air inlet edge at the same side as the side edge is 0.30-0.35 time of the width of the air distributor. Air distributing holes are uniformly distributed on the air distributor and have diameter in the range of 150-165 mm, and the opening rate of the air distributor is 0.32-0.40. The invention has the advantage that the device can make the dust-containing smoke flow into the deduster box in a high flow distribution uniformity.

Description

technical field [0001] The invention relates to a bag type dust collector and an electric bag composite dust collector, in particular to a three-dimensional air distribution device at the inlet of the dust collector. Background technique [0002] The structure of the bag type dust collector and the electric bag composite dust collector both include a dust collector box and a trumpet-shaped smoke inlet pipe with a square cross-section formed by four side panels. chamber and the lower flue gas chamber, a number of filter bags connected to the upper clean gas chamber are hung on the flower plate, an air inlet is opened on the side wall of the lower flue gas chamber of the dust collector box, and a Air outlet; the large-diameter nozzle of the trumpet-shaped smoke inlet pipe is connected with the air inlet of the flue gas chamber under the dust collector box, and the gas outlet of the clean air chamber on the dust collector box is connected with the smoke outlet pipe. The filter...

AI Technical Summary

Problems solved by technology

The filter bag is a key component of dust collectors such as bag filter and electric bag composite dust collector. Preventing the filter bag from being damaged is of great significance to the stable operation of the dust collector; Uneven air distribution of dust and flue gas and low air distribution uniformity are the main factors causing damage to the filter bag. When the dusty flue gas with uneven air distribution is discharged into the dust collector box, it will cause the dust filtration load of the entire dust collector. Uneven, the filter bag in the area where the airflow is concentrated is relatively large due to the relatively large filter dust load and the relatively high filtering wind speed, and the filter bag is prone to damage. Once the filter bag is damaged, the air flow resistance in the damaged filter bag area will be greater Low, resulting in a more concentrated airflow, which in turn causes a larger area of ​​filter bag damage
