Abstract

The utility model discloses a prevent static filter bag relates to a dust bag, is to constitute by the bag body, bag head and the bag end, the bag body sew up an one end that is fixed in the bag body for tubbiness, bag head, an other end that is fixed in the bag body is sewed up to the lateral wall at the bag end, the bag end appears for the round platform, bag head insidely be equipped with clamp and spring piston ring, the spring piston ring is adhere in the bottom of clamp. The utility model discloses a prevent static filter bag, its main material is given first place to with mekralon > 70%, low in production cost, filter effect be good, prevent that static electricity effect is good, the control of its base cloth surface resistance makes the whole conducting resistance of filter bag be less than 106 omega at 1011-1012 omega, satisfies the national standard requirement, and simultaneous control filter bag surface charge eliminates speed, the during operation, and filter bag surface potential can be less than the impurity current potential slightly, has just so eliminated the electric charge that gathers, and then has solved the problem that the dust blocks the filter bag.

Description

Antistatic filter bag

Technical field

The utility model relates to a kind of dedusting filtering bag, particularly relates to a kind of antistatic filter bag.

Background technology

In petrochemical enterprise production process, industry gas dust removing is as one of its indispensable link often such as air, nitrogen, in order to remove the foreign material in air, as produced medium dust, reach qualified recycling or discharge standard, because surface sediment electric charge produces static discharge when avoiding sock filtration, cause the accidents such as flash burn, all the time, antistatic filter bag is the first-selection of most petrochemical enterprise dedusting.Tradition antistatic filter bag, often ask most conductive effect, thoroughly to eliminate for the purpose of pocket surface charge, and have ignored because Electrostatic Absorption causes filter bag to block, cause filtration resistance to increase, safeguard the drawbacks such as frequent, when Electrostatic Absorption is serious, filter bag may be caused cannot to continue to use, increase enterprise's production cost.

Summary of the invention

The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of antistatic filter bag.

Antistatic filter bag of the present utility model, form by the bottom of bag, bag head and bag, described bag is tubbiness, bag head sews up the one end being fixed on bag, the bag end is truncated cone-shaped, the sidewall at the bag end sews up the other end being fixed on bag, and described bag head inside is provided with clip and spring piston ring, and spring piston ring is bonded in the bottom of clip.

As further improvement of the utility model, described bag, bag head and the filter cloth at the bottom of bag are all twist Split Down by polypropylene fibre filament fiber, absorbent cotton filament fiber and stainless steel fibre, woven mutually formed by warp, latitude.

As further improvement of the utility model, described bag, bag head and the surface at the bottom of bag are all covered with poly tetrafluoroethylene.

As further improvement of the utility model, described clip is the concave structure that strip filter cloth both sides turnup is sewed up.

As further improvement of the utility model, described spring piston ring is stainless steel.

Antistatic filter bag of the present utility model, its base cloth adopts polypropylene fibre, degreasing cotton fiber, stainless steel fibre reasonably combined, and its advantage is: one, main material is with polypropylene fibre for main > 70%, and production cost is low; Two, appropriate collocation natural fine fiber-degreasing cotton fiber being evenly arranged, can reach expection filter effect; Three, add stainless steel fibre in right amount, filter bag electric conductivity and the point discharge of charge discharging resisting function metal fine fibre can be increased, increase anti-static effect; Four, scrim surfaces resistance controls at 1011 ~ 1012 Ω, the overall conducting resistance of filter bag is made to be less than 106 Ω, meet national standard requirement, control filter bag surface charge release rate simultaneously, during work, filter bag surface potential slightly lower than impurity current potential, can thus eliminating the need the electric charge gathered, and then solves the problem of dust obstruction filter bag.

Detailed description of the invention

As shown in Figure 1, antistatic filter bag of the present utility model, by 2 forming at the bottom of bag 1, bag 3 and bag, described bag 1 is tubbiness, and bag 3 forms for filter cloth is folding, and the one end being fixed on bag 1 is all sewed up on two limits after bag 3 doubling, the sidewall at the bag end 2 sews up the other end (as Fig. 3) being fixed on bag 1, the bag end 2 be truncated cone-shaped, this structure can make bag 1 with at the bottom of bag 3 sews up more closely, placement dust overflows from interface; Described bag 3 inside are provided with clip 4 and spring piston ring 5, described clip 4 is the concave structure that strip filter cloth both sides turnup is sewed up, the groove formed is for being fixed on cleaner, and described spring piston ring 5 is stainless steel, and spring piston ring 5 is bonded in the bottom (as Fig. 2) of clip 4; At the bottom of described bag 1, bag 3 and bag, the filter cloth of 2 is all twist Split Down by polypropylene fibre filament fiber (> 70%), absorbent cotton filament fiber (15% ~ 20%) and stainless steel fibre (6% ~ 7%), weave mutually form by warp, latitude, polyphenylene sulfide fibre, Fypro, polytetrafluoroethylene fibre, stainless steel fibre are evenly distributed state, its main material is polypropylene fibre filament fiber, low production cost; At the bottom of described bag 1, bag 3 and bag, the surface of 2 is all covered with poly tetrafluoroethylene, strengthens the effect that industrial gasses filter.
