Abstract
The utility model discloses a dust removal filter media for ferro -silico -manganese stove, it includes the fine base cloth layer of glass, the upper and lower surface on the fine base cloth layer of glass is equipped with blend fibre layer and composite bed respectively, blend fibre layer upper berth is equipped with the P84 fibrous layer, the blend fibre layer is formed by P84 fibre and aramid fiber mixture. Its beneficial effect lies in: the utility model provides a pair of a dust removal filter media for ferro -silico -manganese stove, it forms the counter -bending and resistant higher compound filter media of folding endurance through the multilayer material, can effectively increase the intensity that makes the filter bag, reduces the impaired rate of filter bag in the use, improves filter bag life, reduce cost.
Description
[technical field]
The utility model relates to a kind of fabric for dedusting filtering bag, particularly a kind of dedusting filter material for ferro-silico-manganese stove.
[background technology]
Current sack cleaner is glass filter material or glass overlay film filter material at the normally used filter material of ferro-silico-manganese smelting furnace, though high temperature resistant, corrosion-resistant, dimensionally stable, glass is crisp, counter-bending and folding resistance is poor.Not only flue-gas temperature high (250 ~ 280 DEG C) in ferro-silico-manganese smelting furnace, and have the easy moisture absorption of dust, ratio resistance high, the characteristic that dust content is large, smoke granularity is superfine (be less than 0.3um and account for 99.9%), so vibration or pulse dust cleaning dynamics just need to strengthen, in addition soot emissions rate variation is large, in actual production, the vibration of this great dynamics or pulse dust cleaning very easily cause glass filter material (bag) injured and demoulding, breakage halfway.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, for the normally used glass filter material of current ferro-silico-manganese smelting furnace dedusting very easily injured and midway demoulding, damaged deficiency, a kind of dedusting filter material for ferro-silico-manganese stove is provided, it forms counter-bending and that folding resistance is higher Compound filtering material by multi-layer material, effectively can increase the intensity of obtained filter bag, reduce the filter bag loss percentage in use procedure, improve life of bag filter, reduce costs.
The technical solution of the utility model is achieved in that a kind of dedusting filter material for ferro-silico-manganese stove of the present utility model, its improvements are: it comprises glass base cloth layer, the upper and lower surface of described glass base cloth layer is respectively equipped with blend fibre layer and composite bed, described blend fibre layer is equipped with P84 fibrage, and described blend fibre layer is mixed by P84 fiber and aramid fiber.
In said structure, described composite bed is composited by P84 fiber, aramid fiber and glass.
In said structure, the fibrolaminar thickness of described P84 is 0.1 ~ 0.3mm.
In said structure, the thickness of described blend fibre layer is 0.1 ~ 0.1mm.
In said structure, the thickness of described blend fibre layer is 0.5 ~ 0.8mm.
In said structure, the thickness of described blend fibre layer is 0.2 ~ 0.3mm.
The beneficial effects of the utility model are: a kind of dedusting filter material for ferro-silico-manganese stove that the utility model provides, it forms counter-bending and that folding resistance is higher Compound filtering material by multi-layer material, effectively can increase the intensity of obtained filter bag, reduce the filter bag loss percentage in use procedure, improve life of bag filter, reduce costs.
[accompanying drawing explanation]
Fig. 1 is a kind of dedusting filter medium structure schematic diagram for ferro-silico-manganese stove of the present utility model.
In figure: 1, P84 fibrage; 2, blend fibre layer; 3, glass base cloth layer; 4, composite bed.
[detailed description of the invention]
Below in conjunction with the drawings and the specific embodiments, the utility model is further described:
With reference to shown in Fig. 1, a kind of dedusting filter material for ferro-silico-manganese stove that the utility model discloses, adopt four-layer structure to be composited, top layer is P84 fibrage 1, non-thermal shrinkage fiber, has outstanding resistance to elevated temperatures (transient temperature can reach 280 DEG C) suitable with glass; Fibre section is irregular three leaf lobe shapes, adds the surface area of filtration, and the efficiency of trapping minuteness particle is 2 times of other fibers, and dust can not infilter filter material; Stripping performance is good, reduces Pressure Drop; Solve ferro-silico-manganese working condition dust thin, easily embed filter material inner, blocking filter material increases the problem of running resistance; The second layer is the blend fibre layer 2 adopting P84 fiber and aramid fiber (polyamide) to be mixed, and aramid fiber system flexible macromolecule fiber, has good mechanical performance, and rub resistance, toughness are 2 times of steel wire, and weight is 1/5 of steel wire; Also belong to non-hot shortness's high-temperature fibre, just start carbonization in temperature higher than when 370 DEG C; Price, far below P84 fiber, with P84 fiber blend, can reduce product cost, is applicable to again ferro-silico-manganese smelting furnace duty requirements; Third layer is glass base cloth layer 3, and corrosion-and high-temp-resistant, good stability of the dimension, greatly reduce cost; Bottom is composite bed 4, and it adopts P84 fiber, aramid fiber and glass to be composited, and its performance is good, and cost is low.
The fiber of this filter material and structural allocation, play the advantage of P84 fiber, aramid fiber, glass three kinds of materials well, in addition filter material grammes per square metre is higher, namely the advantage of glass filter material is maintained, overcome again that glass filter material folding resistance is poor, the midway deficiency such as demoulding, breakage, strainability is far superior to glass filter material, filtering accuracy 99.992%, this filter material has good filter effect to bottom successively from top layer, and it is contrary, have good ash-removal effect to top layer successively from bottom, this filter material is applicable to being made into the dedusting of filter bag for ferro-silico-manganese stove very much.
Described above is only preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to restriction of the present utility model.In technological thought category of the present utility model, can occur various distortion and amendment, all those of ordinary skill in the art, according to describing retouching, the amendment made above or equivalent replacing, all belong to the scope that the utility model is protected.
