Abstract
The invention relates to a basalt composite filter material used for high-temperature flue gas dedusting system and a preparation method thereof. The components of the filter material comprise a base layer (1) and a surface layer (2), wherein woven cloth woven through a basalt fiber machine is adopted by the base layer (1); tanlon superfine fibre (3) is adopted on the surface layer; and the surface layer (2) is sprayed on the base layer (1) through a spunlacing technique. The preparation method for the filter material comprises the steps as follows: basalt warps (4) and basalt wefts (5) are woven to obtain the woven cloth; then the woven cloth is used as the base layer (1) and then a water jet flow generated by the tanlon superfine fibre (3) under a spunlacing pressure of 120-240bar is sprayed on the base layer (1) to form a composite filter material with the base layer (1) by spunlacing, thus obtaining the basalt composite filter material. The basalt composite filter material has high strength, can resistant high temperature, has good filter effect and long running resistance, can prolong the service life of a filter bag, and is suitable for dust collection systems like industrial furnaces and kilns, etc. The preparation method is simple and the cost is lower.
Description
Technical field
The invention belongs to sack cleaner corollary apparatus and preparation field thereof, particularly relate to basalt composite filtering material that a kind of high temperature fume dust removal system uses and preparation method thereof.
Background technology
Bag-type dusting is that the porous filter medium of the three-dimensional solid of utilization comes the dust in the separation and collection gas.Along with development of science and technology, the appearance of filtrate and the improvement of ash-clearing technology, the ratio of bag-type dusting in collecting method is more and more big.At present, sack cleaner is widely used in numerous areas such as electric power, iron and steel, cement, coloured, waste incineration, different flue gas environment bag-feeding deduster filtrates have proposed new requirement, the sack cleaner filtrate also relies on each other with bag type dust removing technology, mutually promote, complement each other, constantly advance.
Filtrate is the main replacing accessory of sack cleaner.Strict day by day along with the boiler smoke discharge standard, also more and more stricter for the requirement in the filter efficiency of the filtrate that uses in the sack cleaner, service life etc.The bag-type dusting filtrate mainly is to adopt the conventional needle acupuncture manipulation to produce at present, but for inorfil material filtrate, because the fiber loss rate is bigger in traditional carding process, the product strainability and the service life of making are not ideal enough.And traditional woven cloth is lower for thin dust granules thing arresting efficiency.
Summary of the invention
Technical problem to be solved by this invention provides basalt composite filtering material that a kind of high temperature fume dust removal system uses and preparation method thereof, and this filtrate intensity height is high temperature resistant, good filtration effect, running resistance is low, can prolong the service life of filter bag, is suitable for dust pelletizing systems such as industrial furnace; Preparation method of the present invention is simple, and cost is lower.
The basalt composite filtering material that a kind of high temperature fume dust removal of the present invention system uses comprises basic unit and top layer, and wherein basic unit adopts the woven woven cloth that obtains of basalt fibre, and fragrant sulfone synthetic fibre superfine fibre is adopted on the top layer, and the top layer is ejected in the basic unit by water jet process.
The preparation method of the basalt composite filtering material that a kind of high temperature fume dust removal of the present invention system uses comprises:
With basalt warp thread and basalt weft yarn woven woven cloth, then with described woven cloth as basic unit, (the fine water jet of multiply that water thorn pressure 120～240bar) produces is ejected in the above-mentioned basic unit by high pressure with fragrant sulfone synthetic fibre superfine fibre again, with basic unit's water thorn formation composite filtering material, promptly.
The composite filtering material of gained in the said method is carried out PTFE (polytetrafluoroethylene (PTFE)) mass-impregnation and coating processing.
The present invention adopts the woven cloth appearance of producing in the hatching preparation method with the fibrous nonwoven layer of non-woven water jet process formation.
The present invention only needs by the water thorn polysulphonamide fiber to be ejected on warp thread and the mixed woven cloth of basalt that is made into of weft yarn, just can reach the purpose that improves filter efficiency and prolong life of bag filter, and compare with respect to the filtering material that the single needling process of tradition is made, not only reduced acupuncture, be suitable for high temperature flue gas dust collecting systems such as industrial furnace the destruction of fiber but also the use amount of having saved fiber.
Beneficial effect
(1) filtrate intensity height of the present invention, good filtration effect, running resistance is low, and long service life, reduces system operation cost, is suitable for high temperature dust pelletizing systems such as industrial furnace.
(2) directly adopt basalt fibre with the contacted woven cloth of bag cage in the filtrate of the present invention, fragrant sulfone synthetic fibre superfine fibre layer is adopted on the top layer, and for single polysulphonamide fiber Nomex, the present invention can improve the serviceability temperature of filter bag.
(3) the surface layer ultra fine fibrage made by water jet process of the present invention is compared with the filtrate that single needling process is made, and has saved the use amount of fiber.

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 and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications 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.
With basalt warp thread 4 and basalt weft yarn 5 woven woven cloth, then with described woven cloth as basic unit 1, again fragrant sulfone synthetic fibre superfine fibre 3 is ejected in the above-mentioned basic unit 1 by the fine water jet of multiply that high pressure (water thorn pressure 120bar) produces, with basic unit's 1 water thorn formation composite filtering material, promptly.
The present invention directly is enclosed within on bag cage, and when carrying out work, the woven cloth contact of the basalt of basic unit bag cage effectively reduces the contact of dusty gas to fragrant sulfone synthetic fibre superfine fibre.The top layer adopts the superfine fibre layer can effectively stop fine particle, and than the woven cloth of traditional basalt, thereby the porosity that effectively reduces woven cloth improves the arresting efficiency of particle, reduces running resistance.In addition, the present invention will weave with the non-woven preparation method that combines and effectively reduce the destruction of needled conventionally to fiber, and the loss late of fiber is little, and will be significant to prolonging life of bag filter.
