The content of the invention
The technical problem to be solved is to provide a kind of improved structure of dry-type soot defecator, existing to overcome
What the filtration that some purifiers are easily caused that waste gas filter effect is bad, arrange inside purifier was not easy to dismantle asks
The present invention the adopted technical scheme that solves the above problems is：A kind of improved structure of dry-type soot defecator,
Including poly- petticoat pipe, the outfan of poly- petticoat pipe is connected with waste gas inlet pipe, is provided with blower fan, the outfan of waste gas inlet pipe on waste gas inlet pipe
Purification chamber is threaded with, the outfan for purifying chamber is threaded with exhaustor, is provided with activated carbon filter bag, institute in exhaustor
State purification cavity wall and be symmetrically arranged with 2 guide channels in the axial direction, one end of guide channel is closed, and the other end is the beginning, is led
Clip is equipped with to the beginning of passage, 2 relative sides of symmetrically arranged guide channel offer bar-shaped trough, ceramics
The two ends of filter are provided with connection sheet, and connection sheet end is connected with the fixed column coordinated with guide channel, the length of fixed column
More than the thickness of ceramic filter, the purification intracavity is at least provided with activated carbon mistake again in 4 ceramic filters, waste gas inlet pipe
The front end of filter bag is provided with soda lime filter.Existing purifier is typically all using the adsorption material for being filled with porous
Material, removes the harmful substance in waste gas by the absorbability of hole, and it is less that filler is arranged, then cause the purification of waste gas
Effect is bad, if filling is too many, then to cause the blocking of hole, the clean-up effect for also resulting in waste gas is bad；Also, fill out
The filtration for filling formula is not easy to remove, and soda lime filter bag of the present invention refers specifically to inside and is placed with the netted of soda lime
Bag, soda lime can effectively absorb the harmful gass such as sulfide in waste gas, carbide, and the activated carbon filter bag is specifically
Refer to the internal mesh bag for being placed with activated carbon, activated carbon can effectively absorb the penetrating odor in waste gas, described ceramics
Filter specifically refers to a kind of porous ceramic structure, and the particulate matter in waste gas can be carried out effectively to catch precipitation, porous
Ceramics are prior art material, and which has filtration efficiency, low pressure drop, high flue dust carrying capacity and high temperature resistant, resistance to thermal strain
With resistance to thermal contraction, the performance of resistance to chemical attack；Described guide channel is specifically referred to for placing fixed column and realizing fixing
The movement of post, clip are specifically referred to for fixing fixed column, it is to avoid fixed column comes off logical in being oriented to from the beginning of guide channel
Road, the length of fixed column specifically refer to length of the fixed column on guide channel axial direction, and the thickness of ceramic filter is specifically referred to
The length of fixed column is set greater than the thickness of ceramic filter parallel to the thickness on fixed column direction by ceramic filter,
So that there is the gap of certain distance between adjacent 2 ceramic filters, multiple filtration is realized, waste gas is through last layer ceramic filter
Enter back into next layer of ceramic filter to be filtered after entering row buffering in gap after device, improve filter effect, it is to avoid existing
The bad problem of filter effect caused by the single layer filter of purifier filled type, and before activated carbon filter bag in exhaustor
End is provided with soda lime filter bag, to being filtered by purification chamber expellant gas, improves the clean-up effect of gas, activated carbon
The front end of filter bag is specifically referred to where in exhaustor, gas is first flowed through, the course of work of the present invention：By ceramic filter by
Individual to be put into guide channel so that fixed column is arranged in guide channel, connection sheet passes through bar-shaped trough, buckles clip, completes pottery
Porcelain filter is fixed on purification intracavity, then twists the input in purification chamber, outfan respectively with waste gas inlet pipe, aerofluxuss pipe screw thread
Connect, purify the input in chamber, outfan and specifically refer to the inflow end of waste gas, outflow end, poly- petticoat pipe is used for assembling waste gas, waste gas according to
Secondary to filter bag filtration, then the discharge of Jing exhaustors through multi-layer ceramics filter, soda lime filter bag, activated carbon, the present invention's tears open
Unload mode：After turning on purification chamber, clip is opened, ceramic filter is poured out one by one from the beginning in purification chamber, it is simple to operate
It is convenient, thus, instant invention overcomes existing purifier is easily caused, waste gas filter effect is bad, arrange inside purifier
Filtration is not easy to the problem dismantled.
Further, ceramic filter includes expanded metal, if expanded metal outer wall parcel dried layer ceramic fibre.Adopt
Ceramic filter prepared by the mode for wrapping up expanded metal with ceramic fibre, is on the one hand conveniently replaceable ceramic fibre, it is to avoid pottery
The caused ceramic hole plug of porcelain fiber use time length, improves the convenience for using；On the other hand can be given up according to actual
Gas disposal amount and processing speed are made rational use of resources determining the number of plies of ceramic fibre parcel.
Further, the flexure strip coordinated with guide channel is provided with clip.There is flexure strip certain buffering to make
With, it is to avoid rigidity effect when clip is directly contacted with fixed column, be conducive to the clip to fix and protect fixed column.
Further, the internal diameter of waste gas inlet pipe and purification chamber connection end is in the trend for gradually increasing in airflow direction.Can
Play cushioning effect so that the exhaust gas pressure for entering into waste gas inlet pipe is gradually lowered, it is to avoid the too high waste gas direct effect of air pressure
In ceramic filter, and then damage is produced to ceramic filter.
Further, drainage screen is provided with waste gas inlet pipe.The setting of drainage screen can be tentatively filtered to waste gas, will
Larger impurity is intercepted, it is to avoid the purification intracavity that larger impurity is carried out affects the filter effect of ceramic filter.
Further, poly- petticoat pipe is funnel structure, and the less one end of funnel structure internal diameter is connected with waste gas inlet pipe.The leakage
Bucket structure specifically refers to the interior input without leave of poly- petticoat pipe and is gradually reduced to outfan, and the internal diameter of poly- petticoat pipe outfan is arranged
It is larger, be conducive to the absorption to waste gas, improve the absorption efficiency to waste gas.
To sum up, the invention has the beneficial effects as follows：
1st, by arranging guide channel in purification intracavity, the beginning of guide channel is provided with clip, was used for the present invention
The fixed column and guide channel, the cooperation of clip that the ceramic filter of filter waste gas is arranged by its end realizes ceramic filter
Installation and dismounting, it is easy to operate simple.
2nd, it is of the invention by being provided with multiple ceramic filters in purification intracavity, and the two neighboring ceramic filter time sets
Gap is equipped with, multiple filtration is on the one hand realized, filter effect is improve, on the other hand, gap has certain cushioning effect, makes
Waste gas enter row buffering in gap after last layer ceramic filter after enter back into next layer of ceramic filter and filtered,
Improve filter effect.
3rd, the ceramic filter that the present invention is prepared by way of wrapping up expanded metal using ceramic fibre, on the one hand just
In changing ceramic fibre, it is to avoid the caused ceramic hole plug of ceramic fibre use time length, the convenience for using is improved；It is another
Aspect can determine the number of plies of ceramic fibre parcel according to actual exhaust-gas treatment amount and processing speed, make rational use of resources.
