Description
Technical field
The invention belongs to spent acid processing technology field, and in particular to a kind of spent acid single effect evaporation processing unit
Background technology
Acid is in the industry extensive use such as chemical industry, steel.In many production processes, sour utilization rate is very low, substantial amounts of acid
Emitted in company with acid-bearing wastewater.These waste water are such as discharged into environment without processing, can not only make water body or soil acid
Change, ecological environment is caused harm, and waste ample resources.Spent acid and acid waste water are in addition to acidity, also containing a large amount of
Impurity.Harm of the spent acid to underground water is much larger than general wastewater from chemical industry.Specifically, spent acid is while permeating the ground,
River or underground are included by the heavy metal in rock, soil is reacted, severe contamination is caused to river or underground water；Also with rock
Sulphite, sulfide reaction in soil release the pernicious gas such as sulfur dioxide and hydrogen sulfide.If in addition, spent acid is not using conforming to
Reason, for producing the fertilizer type product such as phosphate fertilizer, ammonium sulfate, magnesium sulfate, organic fertilizer, nuisance will enter soil with fertilizer, cause
Organic pollution of soil；Irrigated with the water polluted by spent acid, can cause soil acidification, heavy metal in acid soil activity compared with
Height, is easily absorbed by plants, food-safe to cause major hidden danger.
The content of the invention
It is an object of the invention to provide a kind of spent acid single effect evaporation processing unit, solve present in such scheme not
Foot.
In order to achieve the above object, the technical solution used in the present invention is：
A kind of spent acid single effect evaporation processing unit, mainly by spent acid groove, filter, evaporator, separator, crystallisation by cooling
Kettle, centrifuge, recovery acid tank, condenser, recovery tank, vacuum buffer tank and vacuum pump assembly composition, described filter are set
Put on the right of spent acid groove, filter upper right side is provided with separator, the separator upper left corner is connected with filter, and the separator left side is set
There is evaporator and be connected with each other with separator, crystallisation by cooling kettle, crystallisation by cooling kettle upper end connection evaporator are provided with the right of separator
Reclaim acid tank provided with acid tank is reclaimed and be connected to centrifugation in lower end, crystallisation by cooling kettle lower end connection centrifuge, crystallisation by cooling kettle lower right
On machine, reclaim and condenser is provided with the acid tank upper right corner, condenser top is connected with separator, and recycle-water is provided with the downside of condenser
Groove, reclaims and vacuum buffer tank is provided with the right of tank, and vacuum buffer tank is connected with reclaiming tank, and the vacuum buffer tank lower right corner is provided with
Positive sky pump assembly.
The described crystallisation by cooling kettle lower left corner is provided with cooling water inlet, and the crystallisation by cooling kettle upper right corner is provided with coolant outlet.
The present invention reduces former process costs, the former process costs of pickling quality, reduction is not influenceed, pickling quality is not influenceed, real
The continuity of production is showed.Reduce potential safety hazard when spent acid processing and accumulating.Remove contained oil, wax, fat etc. in pickle
Organic impurities, it is ensured that the quality of surface treatment.Significantly reduce environmental pollution.
