Abstract

The utility model relates to a bag type dust collector with a novel gas intake mode and a novel airflow distribution structure, which comprises a dust gas inlet, a gravity separation area, a dust hopper, a filter bag area, an outer wall plate, a dedusting assembly, a purified gas outlet and a card. The bag type dust collector is characterized in that the side of the dust gas inlet is provided with a labyrinth type flow diversion and separation plate group, and the labyrinth type flow diversion and separation plate group is positioned at the inner side of the outer wall plate of the dust collector and the outer side of the filter bag area of the dust collector. The labyrinth type flow diversion and separation plate group comprises two groups of shaping plates which are staggered, buckled, engaged mutually and arranged, and can be in a C shape, or a V shape, or a [ shape, or a ( shape. The utility model has the advantages that a sudden expansion state is formed after airflow containing dust enters the dust collector, and a gas motion trend from bottom to top is formed at the filter bag area by separating the airflow again through the labyrinth type flow diversion plate group; and the utility model is beneficial to removing the dust of a filter bag, is suitable for purifying various gases, is especially suitable for filtering dust with high concentration, large particles and strong grinding property and can enhance the service life of a dust-removal filter bag by more than 1/2, compared with a conventional dust collector.

Description

A kind of sack cleaner that has the gentle distributions structure of novel intake method
Technical field
The utility model relates to the sack cleaner field, particularly a kind of sack cleaner that has the gentle distributions structure of novel intake method.
Background technology
In recent years, because the development of iron and steel and metallurgy industry, make internal and international coke consumption amount in continuous increase, the coking industry development rapidly, dry coke quenching technology is also adopted by most coke-oven plant as environmental protection industry, along with country to newly-built, enlarging coke oven production environmental requirement is more and more stricter, coke oven production, dry coke quenching, coke are stored and transhipment has increased a lot of dust pelletizing systems, sack cleaner is used also more and more, prolong sack cleaner cloth bag service life, guarantee that the safe and effective operation of dust pelletizing system seems particularly important.
The coke dust has very strong chiseling property of mill, the deduster that uses is because the inlet air flow skewness at present, high velocity air carries the phenomenon that dust washes away cloth bag and often takes place, cause the cloth bag local damage, not only cloth bag shortening in service life, also bring influence to safety in production, to this, use the utility model sack cleaner air-flow distribution mode, can be widely used in sack cleaner, make the air-flow that enters the filter bag chamber not have bulky grain, can be used for all gases and purify, be particularly useful for high concentration, bulky grain, the strong dust-filtering of chiseling property of mill, avoiding producing high velocity air carries dust and washes away cloth bag, cause the cloth bag local damage, prolong sack cleaner cloth bag whole service life, for safety in production provides advantage.
Summary of the invention
The purpose of this utility model provides a kind of sack cleaner that has the gentle distributions structure of novel intake method, being widely used in all gases purifies, be particularly useful for high concentration, bulky grain, dust-filtering that chiseling property of mill is strong, can avoid producing high velocity air carries dust and washes away cloth bag, cause the cloth bag local damage, improved the service life of dedusting filter bag greatly.
To achieve these goals, the utility model is by the following technical solutions:
A kind of sack cleaner that has the gentle distributions structure of novel intake method, comprise dirt gas inlet, Gravity Separation district, ash bucket, filter bag district, exterior panel, deashing assembly, pure qi (oxygen) outlet, card, it is characterized in that, at dirt gas entrance side labyrinth type water conservancy diversion separating plate group is installed, labyrinth type water conservancy diversion separating plate group is positioned at the inboard of deduster exterior panel, the outside in filter bag of dust collector district.
Described labyrinth type water conservancy diversion separating plate group is made up of the template of two groups of mutual snap-fit arrangement of dislocation make-up, leaves gas channel between the template, and the gap of gas channel is 10~100mm.
Described labyrinth type water conservancy diversion separating plate group template is C type or V-type or [type or (type.
The Lower Half of casing during described dirt gas inlet is arranged in, its airintake direction is for straight down or horizontal or side direction air inlet.
Compared with prior art, the beneficial effects of the utility model are: at dirt gas entrance side labyrinth type water conservancy diversion separating plate group is installed, form the sudden expansion state after making dust-contained airflow enter deduster, the dust granules that wherein has certain speed and energy directly falls into ash bucket, there is 1/5~2/5 gas to enter the filter bag district approximately by the bottom ash bucket, discharging after filtering, remaining have 4/5~3/5 gas carry fine dusts be diffused in whole guide faces of casing air inlet side, separate once more through labyrinth type deflector group, have only fine dust evenly to enter the filter bag district with air-flow, in filter bag district formation gas motion trend from bottom to top, be beneficial to and remove the filter bag dust, be applicable to that all gases purifies, be particularly useful for high concentration, bulky grain, mill chiseling property strong dust-filtering can improve dedusting filter bag ground service life more than 1/2 than conventional deduster.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, a kind of sack cleaner that has the gentle distributions structure of novel intake method, comprise dirt gas inlet 1, Gravity Separation district 2, labyrinth type water conservancy diversion separating plate group 3, ash bucket 4, filter bag district 5, exterior panel 6, deashing assembly 7, pure qi (oxygen) outlet 8, card 9, labyrinth type water conservancy diversion separating plate group 3 vertically is installed on deduster dirt gas 1 side that enters the mouth, be positioned at the inboard of deduster exterior panel 6, the outside in filter bag of dust collector district 5.
Labyrinth type water conservancy diversion separating plate group 3 is made of the template of two groups of mutual snap-fit arrangement of dislocation make-up, template can be C type (Fig. 2) or V-type (Fig. 3) or [type (Fig. 4) or (type (Fig. 5) template, leave gas channel between two groups of mutual interlock templates of dislocation make-up, the gap of its each gas channel is 10~100mm, the maximum height that the top of dislocation make-up mutual biteplate can be extended is to deduster top card 9, and the minimum constructive height that can extend is a deduster dirt gas inlet 1 to half of height between the deduster top card 9.Highly select to be distributed as principle with the grade of dusty gas, fine particle fraction is many, and the height of labyrinth type water conservancy diversion separating plate group 3 will be high, captures area to improve, and the coarse granule ratio is many, and height just can be shorter.
