Description
Technical field
The utility model relates to the technical field of waste incineration sack cleaner, especially relates to a kind of sack cleaner of anticorrosive square bag cage.
Background technology
Existing sack cleaner, its structure comprises dust collector box body, and box house divides, by card, casing is divided into upper box and lower box, and lower box is provided with smoke inlet, the outlet of the flue gas that upper box is cleaner after being provided with filtration, the card in lower box is provided with dust-removal cloth-bag.The defect that current this traditional sack cleaner exists has: 1, its card hole is round structure, and it is less that filter area accounts for card total area ratio, and deduster is arranged and often taken larger area place; 2, this dust-removal cloth-bag only plays the effect of common filtering smoke, cannot filter bioxin in flue gas further after being applied to garbage combustion device sack cleaner; 3, dust collector box body and card material are carbon steel material, higher for corrosive gas content in flue gas in incineration treatment of garbage process, start-stop frequency is higher, in garbage incinerating system furnace shutdown period and start-stop process, flue-gas temperature is often lower than dew-point temperature, deduster, very easily by sour gas and ash deposits corrosion, shortens deduster service life.
Summary of the invention
For the deficiency that above-mentioned prior art exists, it is little that the purpose of this utility model is to provide a kind of floor space, long service life, the sack cleaner of the anticorrosive square bag cage of good filtration effect.
For realizing above-mentioned object, the utility model provides following technical scheme:
A kind of sack cleaner of anticorrosive square bag cage, comprise casing, in casing, middle part is provided with card, casing is separated into upper box and lower box by card, side near card in upper box is provided with pulse blowing pipe, described card is provided with several square card holes, and the card face in described lower box is provided with the filter bag corresponding with square card hole site and quantity.
The utility model is set to further: described filter bag comprises PTFE thin layer, a PTFE base cloth layer, PTFE fiber and active carbon blended layer and the 2nd PTFE base cloth layer, one PTFE base cloth layer, PTFE fiber and active carbon blended layer are between PTFE thin layer and the 2nd PTFE base cloth layer, and a PTFE base cloth layer is at PTFE fiber and between active carbon blended layer and PTFE thin layer.
The utility model is set to further: described PTFE thin layer fits on a PTFE base cloth layer, is linked together between a described PTFE base cloth layer, PTFE fiber and active carbon blended layer and the 2nd PTFE base cloth layer by the mode of making.
The utility model is set to further: described casing lateral wall and card adopt stainless steel to make.
The utility model is set to further: the downside of described lower box is provided with ash bucket.
The utility model is set to further: the downside of described ash bucket is provided with hand operated gate valve, double-layer linkage unloading valve successively.
The utility model is set to further: described ash bucket is provided with vibrator.
By adopting technique scheme, the technique effect that the utility model reaches is:
1, by changing the structure of sack cleaner card, square structure is changed into by circular configuration in card hole, and this change will effectively increase deduster filter area, reduces deduster floor space, especially waste incineration and generating electricity project floor space is applicable to little, the feature that device layout is compact;
2, adopt PTFE material overlay film activated carbon interlayer filter bag, effectively can prevent Yan gas Zhong bioxin low-temp recovery from becoming, thoroughly remove the harmful substances such as heavy metal;
3, the casing lateral wall of stainless steel and card is adopted to replace casing lateral wall and the card of carbon steel material, effectively prevent flue-gas temperature lower than dew-point temperature corrosion cabinet exterior plate and card, prevent sour gas and dust stratification from causing corrosion to casing and card, while reaching deduster structural strength, greatly reduce the weight of deduster.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural principle schematic diagram of the present utility model.
Fig. 2 is the structural principle schematic diagram of card of the present utility model.
Fig. 3 is the sectional structure principle schematic of cloth bag of the present utility model.
Detailed description of the invention
With reference to Fig. 1 ~ 3, a kind of sack cleaner of anticorrosive square bag cage disclosed in the utility model, in casing, middle part is provided with card 11, casing is separated into upper box 10a and lower box 10b by card 11, side near card 11 in upper box 10a is provided with pulse blowing pipe 12, described card 11 is provided with several square card holes 13, assuming that in length be same size two pieces of square cards on offer circular with square card hole, spacing between the adjacent card hole of two pieces of cards and card bore dia D all identical, then under the condition that filter bag length is identical, calculate filter area: the area in square card hole is D
2the area π (D/2) in the circular card hole of >
2.By this result of calculation, at the deduster of same size, adopt square card pore structure can obtain the filter area more strengthened.Application the present invention will reduce the floor space of sack cleaner, be applicable to incineration treatment of garbage project.
Card face in described lower box 10b is provided with the filter bag 14 corresponding with square position, card hole 13 and quantity, filter bag 14 comprises PTFE thin layer 15, a PTFE base cloth layer 16, PTFE fiber and active carbon blended layer 17 and the 2nd PTFE base cloth layer 18, one PTFE base cloth layer 16, PTFE fiber and active carbon blended layer 17 are between PTFE thin layer 15 and the 2nd PTFE base cloth layer 18, and a PTFE base cloth layer is at PTFE fiber and between active carbon blended layer and PTFE thin layer.Described PTFE thin layer utilizes pressure and high temperature to fit on a PTFE base cloth layer, and the mode of being made by needling technique between a described PTFE base cloth layer, PTFE fiber and active carbon blended layer and the 2nd PTFE base cloth layer is linked together.Containing layer flue gas by PTFE thin layer, filter the flying dust in flue gas, PTFE fiber and the active carbon blended layer material such as bioxin and heavy metal in further smoke treatment again, makes pollutant emission in flue gas be down to minimum simultaneously.
Technical term in above-mentioned is explained: PTFE: polytetrafluoroethylene (PTFE), has high, high temperature resistant, the corrosion resistant feature of intensity.
In above-mentioned, casing lateral wall and card 11 adopt stainless steel to make.The downside of described lower box 10b is provided with ash bucket 19, and the downside of ash bucket 19 is provided with hand operated gate valve 20, double-layer linkage unloading valve 21 successively, ash bucket 19 is provided with vibrator 22.
Dusty gas enters sack cleaner lower box from gas approach by sack cleaner smoke inlet 23 (arrange cloth bag bin number of chambers amount according to exhaust gas volumn, this sentences two bins is example).By sock filtration, the flying dust in flue gas is attached to filter bag overlay film surface.Clean gas after filtration, by card hole, enters upper box and is connected with exhaust pass to exhanst gas outlet 24.Jetted by pulse blowing pipe, will the flying dust blowback of filter bag film surface be attached to in ash bucket.Flying dust is under vibrator and Action of Gravity Field, and manually unloading valve, double-layer linkage unloading valve are expelled to deduster.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
