Embodiment Construction

[0029] Adopting the straight-through diversion bag filter proposed by the present invention, the applicant implemented it in the No. 3 boiler flue gas purification and dust removal renovation project of Henan Jiaozuo Power Plant.

[0030] Boiler original parameters:

[0031] ●Boiler type: Ultra-high pressure primary reheating cycle pulverized coal boiler;

[0032] ●Flue gas volume: 400000×4m 3 / h;

[0033] ●Flue gas temperature: 160℃;

[0034] ●Boiler generator set: 220MW;

[0035] ●Boiler evaporation capacity: 670t / h;

[0036] The specific implementation steps are as follows:

[0037] 1. Install the shell of the straight-through diversion bag filter 3, the air inlet 1, the inlet speaker 2, the air outlet 4, and the ash hopper 12.

[0038] 2. Install a deflector 5 in the air inlet 1 of the dust collector, install a partition 7 in the inner space of the dust collector housing, and install an air distribution element 6 in the inlet horn 2 of the dust collector.

[0039] 3. ...

Abstract

A through guide type bag duster for the duster contained fume is composed of air inlet with guide plate, inlet horn with airflow distributor, casing with internal buckheads, air outlet, filtering bag and its cage, patterned plate, dust remover, air exhaust chamber and dust hopper.

Description

1. Technical field [0001] The invention relates to a bag-type dust collector, in particular to a large-scale bag-type dust collector used in the field of environmental protection for purifying dusty flue gas with a large air volume. 2. Background technology [0002] The bag filter is a kind of dust removal equipment that uses filter bags made of filter cloth to filter dusty gas and separate solid particles from the gas. It is widely used in industry. Compared with other types of dust collectors, the advantage of bag dust collectors is high dust removal efficiency, especially the ability to effectively capture fine particles (<10μm particles) in smoke and dust, but its disadvantage is that the equipment has a relatively large operating resistance, generally at The range of 1200-1800Pa ranges from 1200 to 1800Pa, and sometimes even exceeds 2000Pa. High running resistance means high energy consumption of gas flow. Therefore, how to reduce the running resistance of bag filter...
