Abstract

The utility model discloses an industrial waste water vacuum distillation purifier, which belongs to the technical field of waste water purification processing, in particular to the vacuum distillation purification technology. The industrial waste water vacuum distillation purifier is characterized in that the principle that the boiling point of water is reduced with the reduction of pressure is used to greatly reduce the heat needed for changing the boiling waste water from a liquid state to a gas state in a vacuum container. Moreover, the needed heat is the heat that which shall be discharged out by a vacuum pump and a special heating device is not needed; meanwhile, the substances with high boiling point in the waste water can not be boiled, gasified and are held back, and the water in the waste water is completely vaporized, condensed and recycled to realize zero discharge of the waste water. The purifier comprises the distillation body, the vacuum pump and the afterheat collector of a cylinder container; a waste water vacuum distillation area, a condensing cavity, a waste water storage cavity and a heat exchanger are spaced in the distillation body; the industrial waste water vacuum distillation purifier has the positive effects of being beneficial to saving energies and reducing emission, recycling water resources, and providing an industrial waste water vacuum distillation purifier which is applicable to the practical use in industry and is environmental friendly to the market.

Description

Industrial wastewater vacuum distillation purifier

Technical field

Belong to the purification of waste water processing technology field, exactly relate to technology for treating industrial waste water, the vacuum distillation purification techniques.

Background technology

Can have a large amount of waste water or sewage in the industrial processes, for example other part of producing of industry be cleaned and will produce waste water, how handling this waste water is the problem that each industrial enterprise faces.

The treatment process of current back yard industry sewage-treatment plant has mostly adopted large-scale sewage treatment process and technology, and the sewage emissions amount does not reduce.Concrete grammar is: coagulation → flocculation → clarification → filtration; Also have and adopt membrane filtration technique.Preceding a kind of method floor space is big, and the structure of capital construction complexity, and operational management requires high; Then a kind of method then because the suspended particulates amount is easy to stop up film greatly, causes operating cost very high.Preceding a kind of method is to discharge after the sewage disposal, and a kind of method in back often also will just can make waste water obtain reuse by coagulation and the flocculation in preceding a kind of method.Water environment is recovered to prove with the practical experience of regeneration both at home and abroad, have only advanced treatment of wastewater and reuse, could realize healthy water circulation, that is to say, only accomplish that discharging is far from being enough after the sewage disposal, must advance effective utilization of advanced treatment of wastewater and regeneration, i.e. purification of waste water is recycled.

Summary of the invention

The technical scheme that the utility model is taked:

Adopt the distil(l) method, this method will make it gasification to the waste water heating, purge vapor is cooled to purifies waste water then, so this method will consume a large amount of energy.In order to reduce energy resource consumption, adopt vacuum distillation, and do not need special heater, the waste heat that must discharge when only needing vavuum pump work gets final product, its apparatus structure is: the waste water vacuum distillation purifier, comprise distillated subject, the structure of distillated subject is: the cylindrical container at the bottom of the band hemispherical, the subordinate has the lower clapboard of inclination near, on have the funnel-form upper spacer be separated into the sealing shape condensation chamber, vertical fixing the heat exchanger of the hollow pipe formation of band heatsink transverse sheet in the condensation chamber, and heat exchanger respectively passes upper and lower dividing plate respectively; The funnel place of upper spacer, sealing shape ground is connected with the pipeline head, and passes lower clapboard; The top of upper spacer, three springs of vertical hanging under the spherical shape upper cover of top, the broken bubble baffle plate of opening breeder tube that the level of playing is put constitutes waste water vacuum distillation district; Upper and lower in waste water vacuum distillation district is respectively arranged with upper limit liquid level meter and bottom limit level device; On distillated subject upper cover top, pass the vacuum suction pipe of band temperature detector, vacuum suction pipe and vavuum pump upper end join, and the vavuum pump lower end is connected with the surge chamber upper end, the surge chamber lower end then is subjected to the vapour-liquid recovery tube of temperature control valve control, and the vapour-liquid recovery tube inserts the top of the condensation chamber of distillated subject; The bottom of condensation chamber picks out pure water pipe along the end that has a down dip of lower clapboard, is connected with the travelling expenses shape remaining heat trap of waste water fluid storage tank, and the exit of remaining heat trap and water purification outlet pipe join; Waste water fluid storage tank upper end is inserted with wastewater inlet pipe, and there is the blow-off pipe of blowdown water valve control the lower end; And vertically be inserted with outside the vacuum dehydration pipe outlet box, feed the liquid level top of the waste water reservoir compartment of distillated subject by stop valve; Between vapour-liquid recovery tube and pure water pipe, be connected with the bypass pipe of band bypath valve; The recessed bucket place of funnel-form upper spacer, a logical vertically downward pipeline passes lower clapboard, and passes from the distillated subject sidewall, is connected with the straight tube middle part, and the band flushing valve of straight tube top is a water inlet pipe; Straight tube bottom band blowoff valve is a discharge pipe; The discharge pipe below is the residue collection case; The bottom of waste water reservoir compartment is spherical capping down, passes down capping and draws the drainpipe that is subjected to draining valve control vertically downward, and there is sewage collecting box the drainpipe below; More than all members place in the frame, constitute industrial wastewater vacuum distillation purifier.

The good effect of implementing this back utility model is:

The utility model adopts the distil(l) method of vacuum gasifying and cooling; can avoid by municipal pipeline discharging or vehicle-mounted transportation waste water; social resources have greatly been saved; and can recycle used heat on the structure; realize the few energy of consumption and sewage is made advanced treating, make the treated one-tenth pure water of sewage obtain reuse, effectively utilize water resource; remove blowdown, protected environment.For market provide volume little, be suitable for industrial practicality, meet the industrial wastewater vacuum distillation purifier of environmental protection.
