Mixing-type bag dust collector

Abstract

The invention specifically relates to a mixing-type bag dust collector, which comprises a housing, a filtering bag, dust hoppers, an air inlet, and an air outlet. The dust hoppers are connected to the bottom of the housing. The air inlet includes a left air inlet and a right air inlet, wherein the left air inlet is connected to a left end of an expanded pipe, and the right inlet is connected to a right end of the expanded pipe. The expanded pipe is located at the middle part of a lower end of the housing and comprises an expanded pipe I, an opening, and an expanded pipe II, wherein the expanded pipe I has the same structure, shape, and size as that the expanded pipe II does; a transverse section of the expanded pipe I gradually increases from left to right; and the right side of the expanded pipe I is connected to the opening. A right end of the opening is connected to a left side of the expanded pipe II. The opening includes an upper opening and a lower opening. An ion fan is located above the filter bag and comprises a hood. A plane where a lower end face of the hood is is located above a plane where an upper end face of the filtering bag is. Based on the reasonable structure design, the work efficiency and safety of the mixing-type bag dust collector is greatly improved.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to a hybrid bag filter. Background technique [0002] The bag filter is a dry dust filter device, which is suitable for collecting fine, dry, non-fibrous dust. When the dusty gas enters the bag filter, the dust with large particles or specific gravity will settle due to the action of gravity. It falls directly into the ash hopper, and the gas with finer dust is blocked when it passes through the filter material, so that the gas is purified. The dust adsorbed on the filter bag will increase with the continuous passage of the dusty gas. In order to restore the filter performance of the filter bag in time, it is necessary to clean the filter bag. The time interval between two cleanings is called the cleaning period, but the mixing The bag filter has the following disadvantages in the actual production and use process: the cleaning cycle is not long, which reduces the work efficie...

The dust adsorbed on the filter bag will increase with the continuous passage of the dusty gas. In order to restore the filter performance of the filter bag in time, it is necessary to clean the filter bag. The time interval between two cleanings is called the cleaning cycle, but the mixing The bag filter has the following disadvantages in the actual production and use process: the dust cleaning cycle is not long, which reduces the work efficiency, and the dust accumulated on the filter bag is dangerous, which reduces the safety performance of the mixed bag filter
