Description

Dedusting filtering bag

Technical field

The utility model is related to a kind of bag filter more particularly to a kind of dedusting filtering bags.

Background technology

In recent years, as National urban house refuse amoun is with the speed sustainable growth every year higher than 10%, national 660 cities Have 200 cities in city to be absorbed among rubbish encirclement, garbage disposal is extremely urgent.Subtract due to carrying out burning disposal to rubbish Hold, decrement and innoxious degree it is all very high, the heat that burning process generates is used for generating electricity can realize the energy of rubbish again simultaneously Change, waste incineration and generating electricity industry is just attract more and more capital acceleration and pouring in this environmental protection industry (epi), in a few years, respectively Ground starts waste incineration project one after another, and the garbage power plant of whole nation planning and operation just has more than 100, and waste incineration is in the ascendant.

Since China's municipal refuse organic matter composition is high, moisture content is high, cause the flue gas after incineration treatment of garbage that there is height The features such as temperature, high humidity, strong corrosivity so that requirement of the incineration treatment of garbage treating tail gas to filtrate is quite harsh.Waste incineration Power generation regulation must use sack cleaner, and the effect of the filtrate as sack cleaner core is apparent.

The public number Chinese patent for CN201085970Y discloses a kind of Sack dust-collecting equipment of blowback, has babinet, case It is connected above body with outlet air manifold, lower box is connected with flue-dust retainer, and flue-dust retainer top is connected with blast pipe；It is equipped in babinet At least two bag filters, each bag filter have the skeleton being fixedly connected on babinet, the cloth being arranged on outside skeleton The empty nozzle of blowback compression of bag and deashing；At least one piece of vertical baffle is equipped in the babinet, so as to by babinet be isolated into Lack 2 deashing chambers, be all provided in each deashing chamber there are one bag filter, and control is equipped between each deashing chamber and outlet air manifold Valve processed.The utility model can effectively remove the dust filtering of cloth bag surface, the convection current of inverted draft will not be caused to interfere, energy consumption Low, evenly, the connection of cloth bag and skeleton is more secured, more closely for contact of the dust with cloth bag surface.

This Sack dust-collecting equipment of blowback has the following disadvantages：Since flue gas is with a large amount of heat, flue gas is from blast pipe Into babinet directly to blowing to cloth bag, the bottom of cloth bag will be toasted for a long time by high temperature, cause to scald.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of dedusting filtering bag for the deficiency of background technology, High-temperature damage of the flue gas to dust-removal cloth-bag bottom can be alleviated.

The utility model uses following technical scheme to solve above-mentioned technical problem：

A kind of dedusting filtering bag, the cloth bag including tubular, cloth bag bottom are provided with the collet of tubular, and the collet is by hindering Combustion fabric weaves, and composite silicate thermal insulation paint is coated with outside the collet.

Further, super silica silk thread is interspersed in the collet.

Further, the cloth bag includes base cloth layer and filter layer, and the base cloth layer is glass fibre base cloth layer.

Further, the filter layer is PTFE web layer.

Further, the overall thickness of the base cloth layer and filter layer is 1.2mm.

Further, teflon coatings are coated with outside the filter layer.

The utility model compared with prior art, has following technique effect using above technical scheme：

1st, collet is arranged in cloth bag bottom, burnt so as to reduce high-temperature flue gas to cloth bag, filament is interted in collet The intensity of collet can be improved；

2nd, due to the presence of collet, the overall thickness of the thickness for the cloth bag for being, i.e. base cloth layer and filter layer can be relatively It is thin, it is 1.2mm, improves its gas permeability.Teflon coatings are coated with outside filter layer, Teflon has good adhesion, energy Enough reduce the accumulation of dust.

Description of the drawings

Fig. 1 is the utility model structure diagram.

In figure, 1, cloth bag；11st, base cloth layer；12nd, filter layer；2nd, collet；21st, super silica silk thread.

Specific embodiment

The technical solution of the utility model is described in further detail below in conjunction with the accompanying drawings：

A kind of dedusting filtering bag, as shown in Figure 1, the cloth bag 1 including tubular, which includes base cloth layer 11 and filter layer 12, For base cloth layer 11 using glass fibre base cloth layer 11, filter layer 12 is PTFE web layer.Base cloth layer 11 and filter layer 12 Overall thickness be 1.2mm.Teflon coatings are coated with outside filter layer 12.

1 bottom of cloth bag is provided with the collet 2 of tubular, and the collet 2 is by flame-retardant fibre fabric and interts super silica silk Line 21 weaves, and composite silicate thermal insulation paint is coated with outside the collet 2.

Explanation is embodied：

Collet 2 is arranged in 1 bottom of cloth bag, so as to reduce high-temperature flue gas burning to cloth bag 1.Collet 2 is using fire-retardant Fabric and intert super silica silk thread 21 weave, interspersed filament can improve the intensity of collet 2.Flame-retardant fibre fabric It has the following advantages：

1st, safety is good.Fiber does not melt when meeting fire, and low cigarette does not discharge poison gas.

2nd, permanent fire retardation.Washing and friction etc. do not interfere with flame retardant property.

3rd, the feature of environmental protection.Using native cellulose fibre as carrier, waste can natural degradation, meet environmental requirement.

4th, excellent permanent fire retardant performance.Propagation of flame, smog release are being prevented, resist melt has in durability Good behaviour.

5th, good thermal insulation and antistatic performance.Comprehensive Thermal protection is provided.

6th, there is natural fiber characteristic.Fabric has moisture absorption and desorption property possessed by natural fiber, and fabric is soft with feel The features such as soft, comfortable, ventilative, bright.

Composite silicate thermal insulation paint is coated with outside collet 2.Composite silicate thermal insulation paint thermal conductivity factor Relatively low, cost is also low.

Due to the presence of collet 2 so that the thickness of cloth bag 1, the i.e. overall thickness of base cloth layer 11 and filter layer 12 being capable of phases To relatively thin, for 1.2mm, its gas permeability is improved.Teflon coatings are coated with outside filter layer 12, Teflon has good adhesion Property, the accumulation of dust can be reduced.

Those skilled in the art of the present technique are it is understood that unless otherwise defined, all terms used herein（Including skill Art term and scientific terminology）With the identical meaning of the general understanding with the those of ordinary skill in the utility model fields Justice.It should also be understood that those terms such as defined in the general dictionary should be understood that with upper with the prior art The consistent meaning of meaning hereinafter, and unless defined as here, will not with the meaning of idealization or too formal come It explains.

Above example is only to illustrate the technological thought of the utility model, it is impossible to the protection model of the utility model is limited with this Enclose, it is every according to the utility model proposes technological thought, any change done on the basis of technical solution each falls within this reality Within the scope of novel protected.The embodiment of the utility model is explained in detail above, but the utility model is not It is limited to the above embodiment, within the knowledge of a person skilled in the art, can also be or else detached from this practicality It is made a variety of changes under the premise of novel objective.
