Abstract

The invention relates to a filter bag used for a bag type dust collector. The filter bag comprises a bag body, wherein one end of the bag body is fixedly connected with a bag bottom, and the other end of the bag body is opened. A filter layer of the bag body adopts a composite structure and comprises an outer filter layer and an inner filter layer, wherein the outer filter layer is made of woven fabric of a high-temperature-resistant flame retardant fiber material, and the inner filter layer is made of non-woven fabric of a high-polymer fiber material. The filter bag disclosed by the invention solves the problems that the filter bag of the bag type dust collector in the prior art easily suffers from aging damage and ablation damage. The filter bag is especially suitable for the filtering of dusty smoke in big difference between dust temperature and smoke temperature. In addition, after the high-temperature dusty smoke is filtered by the outer filter layer, high-temperature particulate matters are blocked to form a dust filter layer to make a dust filter action, so that the filter efficiency of the inner filter layer is improved, and the service life of the inner filter layer is prolonged.

Said nonwovens process is water jet process or needling process.
Said heat-resistance and flame-retardant fiber is glass fibre or basalt fibre.
Said macromolecular fibre is polyster fibre or aramid fiber or polysulphonamide fiber or PPS or P84 or PTFE or their composite fibre.
Said bag adopts high temperature resistant sewing thread to sew up and processes.
It is that stitching is sewed up or flushed in interlock that said bag is sewed up the scrap (bridge) mode that is adopted.
Said carvel joint is combined into flanging and flushes stitching or directly flush stitching.
Beneficial effect
The present invention compares prior art and has following beneficial effect:
1) bag of the present invention adopts the composite construction filter course; Outer filter course is the woven cloth filtering layer of heat-resistance and flame-retardant fiber material; The main high-temperature particle thing that filters in the ash-laden gas; The inner filtration layer is the non-weaving cloth filtering layer of polymer fiber material, mainly filters in the ash-laden gas by gas-cooled fine particle, can effectively solve the problem that the filter bag easy ageing of sack cleaner in the prior art is damaged, ablated and damage like this;
2) after the high temperature dust flue gas filtered through outer filter course, the high-temperature particle thing is stopped formed the dust filtering layer, produces the dust-filtering effect, helps improving the filter efficiency of inner filtration layer, can also prolong the service life of inner filtration layer;
3) the used sewing thread of the present invention is high temperature resistant sewing thread, and the scrap (bridge) mode of employing is that stitching (flanging flushes and sews up or directly flush stitching) is sewed up or flushed in interlock, satisfies the requirement of filter bag intensity and filter bag surface heatproof.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in the restriction scope of the present invention.Should be understood that in addition those skilled in the art can do various changes or modification to the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Like Fig. 1~shown in Figure 6; The present invention includes bag, said bag one end was fixedly connected with the bag end, and the other end is open; The filter course of said bag adopts composite construction; Comprise outer filter course 1, inner filtration layer 2, said outer filter course 1 adopts the woven cloth of heat-resistance and flame-retardant fiber material to process, and said inner filtration layer 2 adopts the non-weaving cloth of polymer fiber materials to process.
Said bag cross sectional shape is circular or oval.
Said bag adopts nonwovens process that inner filtration layer 2 is directly combined with outer filter course 1 or adopts sewing process that Manufactured inner filtration layer 2 is combined with outer filter course 1.
Said nonwovens process is water jet process or needling process.
Said heat-resistance and flame-retardant fiber is glass fibre or basalt fibre.
Said macromolecular fibre is polyster fibre or aramid fiber or polysulphonamide fiber or PPS or P84 or PTFE or their composite fibre.
Said bag adopts high temperature resistant sewing thread to sew up and processes.
It is that stitching is sewed up or flushed in interlock that said bag is sewed up the scrap (bridge) mode that is adopted.
Said carvel joint is combined into flanging and flushes stitching or directly flush stitching.
Filter course of the present invention adopts composite construction; Outer filter course 1 is the woven cloth filtering layer of heat-resistance and flame-retardant fiber material; The main high-temperature particle thing that filters in the ash-laden gas; Inner filtration layer 2 is the non-weaving cloth filtering layer of polymer fiber material, mainly filters in the ash-laden gas by gas-cooled fine particle, thereby has solved the problem that the filter bag easy ageing of sack cleaner is damaged, ablated and damage in the prior art; Simultaneously, after the high temperature dust flue gas filtered through outer filter course 1, the high-temperature particle thing is stopped formed the dust filtering layer, produces the dust-filtering effect, helps improving the filter efficiency of inner filtration layer 2, can also prolong the service life of inner filtration layer 2.
