Abstract
The invention discloses a filtering bag applied to a rotary cement kiln tail. The filtering bag comprises a filtering bag body and a mounting ring, wherein the filtering bag body is formed in a way that a mounting section, a middle section and an initial section are detachably connected with one another in sequence; the other end of the mounting section is connected with the mounting ring; the middle section is formed by sewing two layers of glassfibre bulky yarns, and ring-shaped cavities encircling the circumference of the middle section are arranged between the two layers of glassfibre bulky yarns of the middle section at intervals; an openable opening is longitudinally formed in the middle section, and two sides of the opening are connected through a connecting device; aluminium hydroxide powder is filled in the ring-shaped cavities. With the technical scheme, the filtering bag is convenient to disassemble and assemble and to be subjected to soot cleaning; in case part of the filtering bag is worn, the whole filtering bag is not required to be replaced, and as a result, the production cost is reduced. Moreover, a cavity structure is added to the middle section of the filtering bag and is filled with the aluminium hydroxide powder, so that fluorine substances in tail gas can be effectively adsorbed, and accordingly, the filtering effect of the filtering bag is further improved.
Description
Technical field
The present invention relates to a kind of filter bag, especially a kind of cement rotary kiln tail filter bag.
Background technology
Cement plant problem of environmental pollution, particularly dust pollution question are the long-standing of cement manufacturing industry always.In new type nonaqueous cement production line, the kiln hood of cement rotary kiln, kiln tail are the dust pollution sources of cement plant maximum, and kiln hood, kiln tail gas total amount account for 60% left and right of full factory waste gas total amount.The main feature of cement plant revolving cement kiln kiln tail flue dust has: particle diameter thin (average dust size 1-30 μ), high humidity, flue-gas temperature is high and the fluctuation large, and dust inlet concentration high.
At present, domestic cement plant major part is selected the electrostatic precipitator dedusting, and be characterized in: running resistance is low; The overload operation ability is strong, and operational administrative is saved trouble relatively.But electrostatic precipitator must be carried out modifier treatment to improve its efficiency of dust collection to flue gas, if dust emission is controlled strict (being less than the level of 50mg/m3), even the equipment investment of electrostatic precipitator and operating cost increase considerably, also be difficult to reach the emission request of dust.Therefore, sack cleaner more and more becomes the first-selection of cement plant revolving cement kiln kiln tail dedusting in recent years.Especially the area higher than national standard to environmental requirement, from operation stability up to standard, should select bag collector to be advisable.At first the high-temperature flue gas of discharging from the cement rotary kiln tail is used fume afterheat through waste heat boiler, then enter cyclone dust collectors and remove big dust particle, to send into sack cleaner containing raw material gas by blower fan again and remove fine dust, finally by blower fan, through chimney, arrange people's atmosphere.The filter bag that wherein sack cleaner is used is key one ring in filter process, and the filter bag quality has determined filter effect to a great extent.The cement rotary kiln tail filter bag function singleness of prior art, and cause dismounting constant because filter bag is long.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of simple in structure, easy to use, the better cement rotary kiln tail of filter effect filter bag.
The present invention for the technical scheme that solves the problems of the technologies described above employing is: a kind of cement rotary kiln tail filter bag, comprise filter bag body and installing ring, described filter bag body is by construction section, interlude and the initial segment composition that removably connects in turn, the other end of construction section is connected with installing ring, described interlude is made and is formed by two-layer glass buiky yarn, between the two-layer glass buiky yarn of described interlude, be interval with the toroidal cavity arranged around the interlude circumference, described interlude vertically be provided with openable opening, the both sides of opening connect by jockey, be filled with aluminium-hydroxide powder in described cavity.
Described filter bag body is connected by the bonding cloth I in turn by construction section, interlude and the initial segment, and described jockey is also bonding cloth.
The surfaces externally and internally of described filter bag body is covered with the PTFE film.
Beneficial effect: the present invention is owing to adopting detachable segmental structure, make dismounting and the deashing of filter bag convenient, if wearing and tearing appear local, can change the whole piece filter bag, thereby reduced production cost, increased cavity structure in addition in the filter bag in stage casing, the filling aluminium-hydroxide powder, the effective fluorine-containing material in absorption tail gas, further improved the filter effect of filter bag; The vertical deployable device in stage casing can make the filling of aluminium-hydroxide powder convenient.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is I place cutaway view Amplified image in Fig. 1.
In figure, 1, installing ring, 2, the filter bag body, 201, construction section, 202, the bonding cloth I, 203, interlude, 2031, cavity, 2032, vertical expanding unit, 204, the initial segment.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to further concrete detailed explanation.
As shown in the figure, a kind of cement rotary kiln tail filter bag, comprise filter bag body 2 and installing ring 1, described filter bag body 2 is by construction section 201, interlude 203 and the initial segment 204 composition that removably connects in turn, the other end of construction section 201 is connected with installing ring 1, described interlude 203 is made and is formed by two-layer glass buiky yarn, between the two-layer glass buiky yarn of described interlude 203, be interval with the toroidal cavity 2031 arranged around interlude 203 circumference, described interlude 203 vertically be provided with openable opening, the both sides of opening connect by jockey 2032, be filled with aluminium-hydroxide powder in described cavity 2031.
Described filter bag body is connected by bonding cloth I 202 in turn by construction section 201, interlude 203 and the initial segment, and described jockey 2032 is also bonding cloth.
The surfaces externally and internally of described filter bag body 2 is covered with the PTFE film.
A kind of cement rotary kiln tail of the present invention filter bag, before use, interlude 203 is from the both sides of opening, and aluminium-hydroxide powder is inserted in the porch of toroidal cavity 2031, then with bonding cloth by its adhering and sealing, the section of being connected and installed 201, interlude 203 and the initial segment 204 successively.
Use the present invention, owing to adopting detachable segmental structure, make dismounting and the deashing of filter bag convenient, and if local wearing and tearing appear, can displace and damage section and get final product, and needn't change the whole piece filter bag, thereby reduced production cost, increased in addition cavity 2031 structures, filling aluminium-hydroxide powder in filter bag interlude 203, the effective fluorine-containing material in absorption tail gas, further improved the filter effect of filter bag; Opening and jockey 2032 that interlude 203 arranges can make the filling of aluminium-hydroxide powder convenient.
