Embodiment Construction

[0012] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the following embodiments are described in detail in conjunction with the accompanying drawings as follows:

[0013] The accompanying drawings are main / side / overhead / sectional schematic diagrams of the dust collector with the upper outer peripheral air outlet structure and the middle inner air outlet structure type dust collector according to the embodiment of the present invention.

[0014] In this embodiment, the present invention adopts a filter bag dust collector whose main shell is cylindrical in shape. It is mainly adopted that an ash hopper (2) is provided at the lower part of the main shell (1); a rotary plow scraper type ash unloader (3) is installed at the lower part of the ash hopper (2); and a filter chamber (4) is provided at the upper part of the ash hopper (2); A flower plate (5) is installed on the top of the filter chamber (4)...

Abstract

The invention relates to an offline ash removal online overhauling rotary pulse blowing filter-bag dust catcher, which comprises a cylindrical main shell, an ash discharger, a filter chamber, a tube nest, filter bags and an annular clean air chamber, wherein a fixed air storage bag, pulse valves, a compressed air distributor, a rotary driving device and a plurality of rotary pulse blowing pipes are arranged in the center of the main shell; a plurality of insulating plate structures of which the peripheries are provided with sealing devices are arranged above the rotary pulse blowing pipes; offline ash removal hoods are arranged on two sides of each pulse blowing pipe; the tube nest (5) is arranged on the top of the filter chamber (4); the filter bags (6) are arranged between the tube nest (5) and the filter chamber (4) in a concentric circle; an air outlet valve is arranged at an air outlet corresponding to each fan-shaped clean air chamber; and an air outlet pipe is arranged at the periphery of the inside or outside of the main shell. By the offline ash removal online overhauling rotary pulse blowing filter-bag dust catcher, the offline ash removal and online maintenance of the dust catcher can be realized, the ash removal of all filter bags can be completed by a plurality of pulse valves; the installation height of the dust catcher can be reduced effectively; the drag loss of the dust catcher can be reduced; and the running power consumption can be reduced.

Description

technical field [0001] The invention relates to a rotary pulse-jet filter bag type dust collector for off-line cleaning and on-line maintenance, in particular to a bag filter for a cylinder-shaped main shell, which belongs to the technical field of environmental protection equipment. It is widely used in the control of smoke and dust in metallurgy, electric power, chemical industry, construction and other fields. Background technique [0002] In metallurgy, electric power, chemical industry, construction and other fields, there will be a lot of smoke and dust to be treated, which usually requires the use of pulse jet filter bag dust collectors. However, conventional pulse-jet filter bag filters at home and abroad generally have shortcomings and disadvantages such as complex structure, high resistance, large floor area, difficult layout of inlet and outlet air ducts, and offline cleaning but no online maintenance. [0003] In order to effectively control the smoke and dust, ...
