Description

Technical Field

[0001] The utility model relates to the technical field of dust hopper flow diversion of bag dust collectors, and more specifically to a dust hopper flow diversion device of bag dust collectors. Background Art

[0002] The bag filter is a dry dust filter. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag filter, the large particles and heavy dust settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified.

[0003] After searching, a bag dust collector air inlet guide device with an existing announcement number of CN212881500U is found, which includes an ash hopper with a cleaning port and a clean gas outlet, a guide flue connected to the inner cavity of the ash hopper is fixedly arranged on one side of the ash hopper, and a group of parallel guide plates are arranged on the top of the inner cavity of the ash hopper, each guide plate is perpendicular to the cleaning port of the ash hopper, and a multi-stage, variable-section folding plate is used as an air uniform guide device, so that the airflow changes from laminar flow to turbulent flow when entering the ash hopper of the dust collector, and changes to laminar flow with a slower flow rate after entering the filter chamber, thereby optimizing the airflow distribution, improving the dust collection efficiency of the dust collector, and extending the service life of the bag.

[0004] A louver-type guide plate is installed on the air inlet side of the ash hopper of the bag filter in the waste incineration project (the function of the guide plate: after the flue gas passes through the flue gas inlet of the middle box, it enters the air inlet system, and finally is diverted through the ash hopper guide plate to avoid disturbance caused by excessive flue gas flow rate, which causes the filter bag in the middle box to shake and affect the flue gas filtration effect). Because the flue gas from the waste incineration project contains a large number of particles with strong adhesion, the flue gas does not pass well through the louver-shaped guide plate and is very easy to accumulate at the outlet of the air inlet system, until it affects the flue gas treatment effect. Therefore, we proposed a bag filter ash hopper guide device to solve the above-mentioned problems. Utility Model Content
