Abstract
The invention provides a special kiln head filter material for oxynitride in a cement kiln. The base fabric of the filter material is a basalt base fabric; fibrous layers are symmetrically pasted on the upper and lower surfaces of the basalt base fabric by using a needle machine; the fibrous layer is a mixture of basalt fiber composite/chopped basalt fiber/chopped carbon fiber; and the outer surface of the basalt fiber composite is compounded with an organic coating. The special kiln head filter material is high-temperature resistant, and the normal working temperature of the filter material is 320 DEG C; the corrosion resistance of the filter material is good and superior to the corrosion resistance of common needled felt; the filter material has high filtration accuracy, wherein the filtration performance of the filter material is greatly improved by compounding the organic coating on the surfaces facing and not facing dust; and the filter material has a small heat-shrinkage rate and excellent dimensional stability.
Description
Technical field
The present invention relates to filtrate technical field, be specifically related to the special filtrate of a kind of cement kiln nitrogen oxide kiln hood.
Background technology
A large amount of submicron particles that present every profession and trade produces discharge are larger compared with the harm of other particle diameter dust to the mankind and environment, are but difficult to remove.How to collect the difficult problem that chemical industry submicron particles has become aerosol and dedusting circle, our dedusting product yield reaches more than 99%, the most I of dedusting particle radius reaches 0.5 μm, due to running efficiency of system and efficiency of dust collection high, plant running is stablized, for enterprise creates larger economic benefit and social benefit, toxic emission is completely up to standard.
Various raw materials in silicate industry, as the calcining of dolomite, bauxite, clay and metallurgy lime stone, mainly carry out in cement kiln, in calcination process, can produce the tail gas such as a large amount of nitrogen oxide.Dust containing less than 1 μm in cement in vertical kiln discharge gas accounts for 7.92%, less than 2 μm account for 19.05%, less than 3 μm account for 24.83%, existing cement kiln majority adopts filter bag bag-type dust, but the discarded object temperature in kiln is higher, so require higher to the heat-resisting quantity of filter bag cloth bag.
In addition, also there is same problem in the tails dedusting of cement in vertical kiln stove, coal-burning glass stove, coking furnace, the dry kiln of composite fertilizer, municipal refuse dry kiln, pottery and various building materials combustion furnace.
Summary of the invention
in order to overcome the deficiency in background technology, the invention discloses a kind of cement kiln nitrogen oxide kiln hood filtrate.
In order to realize described goal of the invention, the present invention adopts following technical scheme: the special filtrate of a kind of cement kiln nitrogen oxide kiln hood, Ji Bu is Black Warrior batholith cloth, in the upper and lower surface of Black Warrior batholith cloth, needing machine symmetry is adopted to paste fibrage, described fibrage is the mixture of basalt fibre compound/short chopping of glass chopped silk/carbon fiber, the outer surface compositing organic material coating of described basalt fibre compound.
Fibrolaminar dust-collecting face surface recombination coating of organic material of the present invention.
Fibrolaminar non-dust-collecting face surface recombination coating of organic material of the present invention.
Coating of organic material of the present invention is organic siliconresin.
Coating of organic material of the present invention is epoxy resin.
Coating of organic material of the present invention is phenolic resins.
The fibre length of the short chopping of carbon fiber of the present invention is 5 ~ 20mm.
The fibre length of glass chopped silk of the present invention is 0.3 ~ 0.6mm.
Owing to have employed technique scheme, the present invention has following beneficial effect:
1, high temperature resistant, normal working temperature 320 DEG C.
2, good corrosion resistance, is better than general acupuncture felt.
3, filtering accuracy is high: by dust-collecting face and non-dust-collecting face compositing organic material coating, substantially increase the strainability of filtrate.
4, percent thermal shrinkage is little, has outstanding dimensional stability.
5, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, Black Warrior batholith cloth; 2, fibrage; 3, coating of organic material.
Detailed description of the invention
By explanation the present invention that the following examples can be detailed, disclose object of the present invention and be intended to protect all technological improvements in the scope of the invention.
The invention provides a kind of filtrate, Ji Bu is Black Warrior batholith cloth 1, in the upper and lower surface of Black Warrior batholith cloth 1, needing machine symmetry is adopted to paste fibrage 2, described fibrage 2 is the mixture of basalt fibre compound/short chopping of glass chopped silk/carbon fiber, the outer surface compositing organic material coating 3 of described basalt fibre compound 2.
The special filtrate of described cement kiln nitrogen oxide kiln hood by cutting, cutting, the operation such as to make and be processed into the special filter bag of cement kiln nitrogen oxide kiln hood.
The present invention is dropped into actual operating mode to use, through implementing to prove, continuous serviceability temperature of the present invention is 280 DEG C, serviceability temperature is 320 DEG C instantaneously, warp-wise fracture strength >=1800N/520cm, broadwise fracture strength >=1800N/520cm, warp-wise elongation at break≤10%, broadwise elongation at break≤10%, rupture strength >=3.8MPa.
Part not in the detailed description of the invention is prior art.
