Low-pressure injection pulse-jet bag dust collector

Abstract

The invention discloses a low-pressure injection pulse-jet bag dust collector. The low-pressure injection pulse-jet bag dust collector comprises one or more same dust collector units. A flue gas inlet of each one of the dust collector units is connected to an air outlet of the previous dust collector unit. Each one of the dust collector units comprises an injection device, an upper box body, a middle box body, multiple filter-bags, a flow deflector, an ash bucket and an ash discharging device, the upper box body and the middle box body are arranged independently and are isolated by the filter-bags, openings of the filter-bags face upwards, the opening ends of the filter-bags are connected to the upper box body, the upper box body is communicated with the inner cavities of the filter-bags, the filter-bags are arranged in the middle box, the ash bucket is connected to the bottom of the middle box, the bottom of the ash bucket is connected to the ash discharging device, the side of the ash bucket is provided with the flue gas inlet, the side of the upper box is provided with the air outlet, an injection pipe of the injection device is arranged above the filter-bags, the injection pipe is provided with multiple injection holes, the injection holes respectively face to the opening ends of the filter-bags, the flow deflector is arranged in the ash bucket, and a flow deflector plane direction forms an acute angle with a flue gas inlet opening direction. The low-pressure injection pulse-jet bag dust collector has a unit combined structure and has a plurality of specifications according to the number of the dust collector units.

Description

technical field [0001] The technical proposal belongs to the technical field of environmental protection and dust removal, and is specifically a low-pressure jet pulse bag type dust collector. Background technique [0002] The bag filter is a widely used dust removal and filtration equipment. The bag filter encounters more problems that there is more dust attached to the filter bag, which brings about the problem of low dust removal and filtration efficiency. In order to solve this problem, in the prior art, a blowing device is generally used to blow air in reverse pulses into the filter bag to remove the dust on the filter bag. This type of dust collector needs to use compressed air, blowing nozzles, pulse valves and control equipment. For large-scale application scenarios, the dust is relatively large, and a relatively strong pulsed airflow is required to blow off the dust on the filter bag, which requires relatively high power requirements for the blowing equipment.

AI Technical Summary

Problems solved by technology

The more problem encountered by the bag filter is that there is a lot of dust attached to the filter bag, which brings about the problem of low dust removal and filtration efficiency.
