Description
Technical field
The present invention relates to the continuous drying systems and its working method of a kind of slurry or powder, can be applied to phosphorus mud, slag
In the evaporation of phosphorus collect, calcium oxide or calcium chloride, the chemical residual liquor processing of chlorobenzoyl chloride etc., chemical industry finished product is dry, and the three wastes are comprehensive
Close recovery processing, the recycling of the oil such as petrol and diesel oil or machine oil or Organic Chemicals.
Background technique
In the prior art, with producing yellow Phosphorus by electric oven, the wastes such as phosphorus mud, phosphorus slag can be generated, and discarded phosphorus mud, phosphorus slag
In do not produce completely there are also substantial portion of yellow phosphorus, cause the waste of resource in this way.
The method of existing recycling yellow phosphorus has steam filtration method, dry blowing method, chemical reagent reaction method etc.；Steam filtration method
Be phosphorus mud, slag are put into container make the dissolution of phosphorus body refuse with steam laser heating, to become finished product after the phosphorus purification that filters out yellow
Phosphorus still has the P elements of l5-20% that cannot withdraw in treated in this way phosphorus mud, slag, and steam consumption quantity is big, raw
Period length (20 days or so) is produced, is polluted still serious；Dry blowing method is that phosphorus mud, slag are packed into distillation iron pan to heat iron pan, pass through
Phosphorus steam is imported in water bath and is refined into yellow phosphorus by guide pipeline, and this method is unable to continuous production, and efficiency is lower, with this side
Still there are the P elements of l5-20% that cannot withdraw in method treated phosphorus mud, slag；Chemical reagent reaction method is made using carbon disulfide
Extractant, quenching takes yellow phosphorus, and two methods are advanced earlier above for this method, but its process cycle is long, and yield is small, once quenches after taking
Recrement is there are also the phosphorus of 2-5% residual, and operating procedure is complicated, temperature is not easy to control and not easy to control to the quality of yellow phosphorus.
Chinese patent literature CN1152545 discloses a kind of Processes and apparatus that yellow phosphorus is recycled from phosphorus body refuse.This is existing
Technology is disadvantageous in that: being needed to shut down loading, unloading material, be can not achieve continuous work, causes production efficiency lower.
Chinese patent literature CN103591780A discloses a kind of main drying of the continuous drying system of slurry or powder,
It include: main shaft, multilayer annular housing setting up and down；Each annular housing is matched with the main shaft by center through hole movable sealing
On, the material scraping plate being distributed in each annular housing is fixed on the main shaft；There is gap simultaneously between two adjacent annular housings
It is connected by blanking channel sealing；Each annular housing is set in thermally conductive liquid container；The annular housing of top layer be equipped with feeding inlet and
The bottom of exhaust outlet, the annular housing of bottom is equipped with discharge port.The prior art is disadvantageous in that: on multi-layer annular cavity
Lower setting, material biggish for consistency, easily there is a situation where block blanking channel；For runny slurry, then material
It can quickly be flow in bottom annular housing from top annular cavity, lead to not dried material；Secondly, each annular housing is heated not
, the annular housing temperature of bottom is higher, and the annular housing temperature at top is lower.This causes drying temperature control difficulty larger,
The annular housing temperature control of even bottom is excessively high, and material is easy to cause to be carbonized；If the annular housing temperature of bottom is inadequate, lead
Cause material moisture excessively high, i.e. drying is not up to standard.Thirdly, material needs to be sent to the feeding inlet on the annular housing of top layer, right
In mobility is poor or the biggish material of consistency, it is not available pump conveying, causes charging difficult, mainly manually realizes charging,
It is time-consuming and laborious.Again, easily occurs agglomeration layer on each annular housing bottom wall, cleaning is more difficult, while the layer that agglomerates leads to annular housing
Between heat transfer efficiency be greatly reduced, and then seriously affect drying effect.

Object ultimately resides in recovery pond.And in the prior art, the gas containing volatile matter is directly discharged into recovery pond, volatile matter can be with gas
Bubble runs out of the solution of recovery pond, and enters atmosphere, and the rate of recovery of corresponding organic matter is caused to be generally below 60%.(4) cold when working
High pressure liquid stream in lime set input pipe makes to form negative pressure in longitudinal entrance of the threeway, and drives the gas from gas collecting tube
It is sent into drainer；Make gas and condensate liquid before entering drainer with regard to the mixing, the cooling that carry out, conducive to further providing for waving
Send out the condensation effect and the rate of recovery of object.(5) multiple cavities of the invention are vertically arranged and front and back is spaced, so that each annular chamber
Body is heated more uniform when using same burning stove heating；According to electric-heating-wire-heating, the heating temperature of each annular housing can appoint
Individually control, avoidable organic materials are carbonized meaning；Due to the transversely arranged setting of each annular housing, the pan feeding open height phase of cavity
Lower for the prior art, it is convenient, time saving and energy saving to feed.(6) when there is layer of scale on the inner sidewall of each cavity, as long as heating is each
Cavity then rushes each cavity with cold water in outside, is quickly cooled down the side wall of each cavity to certain temperature (such as 100-200 DEG C)
It shrinks, layer of scale can be made to be detached from the inner sidewall.

The connected collection system in channel 6 realizes the collection of volatile matter.
Multiple through-holes are distributed on fan blade, the liquid of condensation top tank structure bottom when fan blade rotates, can be stirred and make liquid
Body atomization；The volatile matter and the liquid of atomization are sufficiently mixed, and are condensed in the drainer, finally from the rear end of drainer
The delivery pipe of bottom is discharged into recovery pond.
After being mixed due to volatile matter with droplet, rapid condensation makes most of volatile matter dissolution in a liquid, and then makes 95%
Above volatile matter ultimately resides in recovery pond.And in the prior art, the gas containing volatile matter is directly discharged into recovery pond, is waved
Hair object can run out of the solution of recovery pond with bubble, and enter atmosphere, and the rate of recovery of corresponding organic matter is caused to be generally below 60%.
The slurry or powder are phosphorus mud, phosphorus slag, or contain the organic matters such as petrol and diesel oil or chlorobenzoyl chloride；Correspondingly, described
Volatile matter is the organic matters such as phosphorus or petrol and diesel oil or chlorobenzoyl chloride.
The slurry or powder may be calcium oxide or calcium chloride.
Obviously, the above embodiment is merely an example for clearly illustrating the present invention, and is not to of the invention
The restriction of embodiment.For those of ordinary skill in the art, it can also be made on the basis of the above description
Its various forms of variation or variation.There is no necessity and possibility to exhaust all the enbodiments.And these belong to this hair
The obvious changes or variations that bright spirit is extended out are still in the protection scope of this invention.
