Purifier is connect with interface by pipeline.
The further technical solution of the utility model is：Purifier includes waste recovery pond, and waste recovery fills in pond
Dedusting liquid is additionally provided with drying outlet port on waste recovery pond.
The further technical solution of the utility model is：Pipe end stretches into waste recovery pond and is located at dedusting liquid liquid
Above face.
Further technical solution is the utility model：Pipe end is apart from 50~100mm of dedusting liquid liquid level.
The further technical solution of the utility model is：Dedusting liquid is water.
The further technical solution of the utility model is：Waste recovery bottom of pond portion is equipped with dedusting liquid discharge port.
The further technical solution of the utility model is：Dedusting liquid discharge port is connected with choline bucket.
The further technical solution of the utility model is：Waste recovery is additionally provided with gauge glass on pond.
The further technical solution of the utility model is：It is additionally provided with exhaust fan on the pipeline that purifier is connected with interface.
Compared with prior art, the utility model has the advantage that：
1. being then exhausted from after " dedusting " that tail gas passes through purifier, the pollution sources content in tail gas is greatly reduced, can be made
The tail gas meet the requirement of environmental protection of discharge；
2. purifier absorbs the dust in tail gas, dust is set to be melted into dedusting liquid, which can continue to make as mother liquor
With, clear water magnitude of recruitment in mother liquor is reduced, it is cost-effective；
3. the dust incorporated in dedusting liquid as mother liquor in use, yield equivalent to increase sodium pyrosulfite, on year-on-year basis
The in line mode of conventional exhaust makes the preparation amount of sodium pyrosulfite rise a step.
The detailed technology scheme of the utility model is further described below in conjunction with the drawings and specific embodiments.
Description of the drawings
Fig. 1 is the simplified diagram of the sodium pyrosulfite drying system of effective ingredient in the recyclable drying exhaust gas；
Fig. 2 is the structural schematic diagram of the purifier.
Specific implementation mode
Embodiment
As depicted in figs. 1 and 2, the present embodiment provides a kind of sodium pyrosulfite bakings of effective ingredient in recyclable drying exhaust gas
Dry systems comprising the sulfur dioxide gas exported in sulphur stove 1, receiving sulphur stove carries out preparing sodium pyrosulfite
Choline bucket 2, the sodium pyrosulfite prepared in choline bucket 2 subsequently enters to be dehydrated in centrifugal dehydrator 3, is dehydrated
It is transported in centrifugal separator 4 and is dried after sodium pyrosulfite afterwards, centrifugal separator 4 has useless for drying to be discharged
The interface of gas, sodium pyrosulfite are also being connected with from the pipeline that centrifugal dehydrator 3 is transferred to centrifugal separator 4 from sulphur stove
Middle generation simultaneously conveys the hot-air come, and hot-air can effectively assist the baking operation of sodium pyrosulfite.
The utility model is intended to the active ingredient in recycling drying exhaust gas, therefore creatively in centrifugal separator 4
Exhaust gas discharge interface connecting pipe 5, the pipeline other end are equipped with the purifier 6 for being dusted to drying exhaust gas.
Purifier 6 specifically includes the interior waste recovery pond 62 for filling dedusting liquid 61, and baking is additionally provided on waste recovery pond 62
Dry outlet port 63, the exhaust gas being discharged from centrifugal separator 5 enter waste recovery pond 62 by pipeline 5, then in dedusting liquid 61
" washing " effect under absorbed sodium pyrosulfite Dust therein, then exhaust gas after processing, which passes through, dries exhaust gas row
63 discharge of outlet, exhaust gas at this time meet environment protection emission requirement.
Because exhaust gas can slightly be dissolved in water, combined to avoid large quantity of exhaust gas from being passed directly into dedusting liquid 61, the present embodiment
Though 5 end of pipeline stretch into waste recovery pond but be located at dedusting liquid ullage, exhaust gas can pass through itself impact force and dedusting
Liquid 61 comes into full contact with, and the dust that dedusting liquid absorbs in exhaust gas reaches dust removing effects.
Specifically, 5 threshold value dedusting liquid of pipeline, 61 50~100mm of liquid level.
The dedusting liquid 61 of the present embodiment is water, and water has very strong adsorbing powder dust effect, without configuring special dedusting
Liquid.
Dedusting liquid measure increasing with adsorbing powder dust in waste recovery pond 62, liquid level will increase, to save artificial behaviour
Make, convenient for being expelled directly out for dedusting liquid, can dedusting liquid discharge port 64 be set in 62 bottom of waste recovery pond, when need to dedusting liquid into
When row cleaning, the dedusting liquid that corresponding amount is discharged in dedusting liquid discharge port 64 is opened.
To save the manufacturing cost of sodium pyrosulfite, the utility model considers that the dedusting liquid recycling that will absorb dust is made
It being used for mother liquor, i.e., dedusting liquid discharge port 64 is connected with choline bucket 2, has so both reduced the clear water magnitude of recruitment in mother liquor,
The yield for also increasing sodium pyrosulfite simultaneously, reduces production cost.
Meanwhile gauge glass 65 is additionally provided on waste recovery pond 62, it is used for removing in monitor passage of waste material recovery pond at any time
Dirt liquid liquid level face.
Specifically, automatic valve can be arranged in dedusting liquid discharge port 64（It is not shown）, while also setting up and gauge glass 65
The solenoid valve of electrical connection（It is not shown）, when gauge glass shows liquid level superelevation, solenoid valve control automatic valve is opened, will be right
The dedusting liquid 61 that should be measured is automatically drained out and has drained the closing that rear solenoid valve controls automatic valve again to choline bucket 2.
For improving production efficiency, it is useless for aspirating that exhaust fan 7 is additionally provided on the pipeline 5 that purifier 6 is connected with interface
Gas avoids exhaust gas from hovering in egress edge, while also allowing for being pumped in exhaust gas centralized in waste recovery pond, keeps gas impact force sufficient
It is enough big.
The structure of the utility model is not limited to above-mentioned concrete mode and structure setting, as long as and the utility model
The technical solution of the close or similar set-up mode of the structure is all fallen within the scope of protection of the utility model.
