Description
Technical field
The present invention relates to industrial cleaning machine technical field, relate in particular to a kind of distillation recovery system.
Background technology
Used cleaning agent in the industry cleaning machine contaminatedly gradually in cleaning process is lost cleaning capacity for the cleaning agent waste liquid.If these cleaning agent waste liquids are directly outwelled, not only increase and clean cost, and can pollute environment.Therefore, need recycle processing to the cleaning agent waste liquid.
Usually adopt the distillation recovery system that the cleaning agent waste liquid is recycled processing, earlier the distillation of cleaning agent waste liquid is obtained cleaning agent volatilization composition, and then the cleaning agent composition condensation of volatilizing is obtained pure cleaning agent.In the distillation recovery system of prior art, needing external heat source usually provides the cleaning agent waste liquid of heat in the heating distillation tank that the low-volatile cleaning agent composition in the cleaning agent waste liquid is taken away in vacuum state evaporation and quilt; Simultaneously, need establish external source in addition is condensed into the cleaning agent composition of extracting out and becomes pure cleaning agent and flow out at condensate tank(trap).This not only needs a special heating so that distillation tank is heated with regard to making, and needs a special refrigeration system be used for the condensation of cleaning agent volatilization composition so that cold to be provided in addition.Therefore, there is baroque defective in existing distillation recovery system.
And; Because present heat, refrigeration system all is to adopt electric energy to carry out work; And we know that evaporation 1 premium on currency needs about 540 caloric heats; And 1 kilowatt of eletctric energy (KWE) can be converted into about 860 caloric heats, even under the situation that energy is very changed, 1 kilowatt energy approximately can only make 1.59 liters water evaporation.That is to say that present distillation recovery system directly utilizes electric energy to heat, freezing exists the defective that energy consumption is high, capacity usage ratio is low, it is unfavorable that enterprise's need energy-saving and emission-reduction that this and current social are advocated require.
In addition, the distillation tank that uses in the present distillation recovery system, its structure is that coil pipe is set in groove.During heating, be connected with the heating agent conduction oil in the coil pipe cleaning agent waste liquid is heated.Because coil pipe produces very high temperature after heating, make the impurity in the cleaning agent waste liquid be prone to be adsorbed near it, just make the coil pipe fouling for a long time.Coil pipe after the fouling the heating distillate the time, be prone to the heating uneven situation.Therefore, this regularly cleans distillation tank and coil pipe with regard to needs, because coil pipe is complicated helical structure, directly cleaning can't be carried out, and must coil pipe be dismantled during cleaning.Therefore, there is the defective of cleaning difficulty in existing distillation tank.
Summary of the invention
First technical problem to be solved by this invention provide a kind of simple in structure, capacity usage ratio is high, the distillation recovery system of saving the energy, to overcome the deficiency that prior art exists.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of distillation recovery system; Comprise distillation tank, carbon dioxide compression device and carbon dioxide pressure reducer; Heater and distillation tank form heating circuit; Cooler forms cooling circuit with condensate tank(trap) and circulating slot respectively, and carbon dioxide compression device, heater, carbon dioxide pressure reducer and cooler form the carbon dioxide refrigeration heating, and said distillation tank, condensate tank(trap), circulating slot are linked in sequence through pipeline.In the present invention, owing to only relate to distillation tank, condensate tank(trap), circulating slot, carbon dioxide refrigeration heating and carbon dioxide refrigeration heating in the whole distillation recovery system thermal source and low-temperature receiver can be provided simultaneously, therefore, the present invention has advantage of simple structure.
In addition, in the carbon dioxide refrigeration heating, on the one hand send heater to, realize heating distillation tank with producing heat in the carbon dioxide compression device carbon dioxide being compressed; On the other hand, pass to cooler and think that condensate tank(trap), circulating slot provide cold with in the carbon dioxide pressure reducer carbon dioxide of high pressure being discharged to obtain cold, same system can heat and can freeze.And this system 1 kilowatt of eletctric energy (KWE) approximately can produce 4300 caloric heats, and its efficient is about 5 times of the prior art, and therefore, the present invention also has the capacity usage ratio height, the advantage that can economize on resources.
Second technical problem to be solved by this invention is that distillation tank can convenient for cleaningly be safeguarded; For this reason; Distillation tank of the present invention comprises cell body and is arranged at the groove lid on the cell body that heating interlayer and said cell body bottom interior wall that said cell body bottom has hollow are pasted with one deck high-temperature resistant membrane.
In distillation tank distillation cleaning agent waste liquid process, bubble can be produced, and impurity can be mingled with in the bubble, in order to access pure cleaning agent volatilization composition, the present invention is in further improving, and said groove lid below is provided with an electromagnetic shaker.This electromagnetic shaker can be shatter with bubble, sneaks into down-stream in the bubble thereby avoided impurity to be mixed in, thereby avoiding influencing reclaims the pure of the cleaning agent that obtains.The heating-up temperature of heater of the present invention is 90-100 ℃; The chilling temperature of cooler is 15-20 ℃.
In order the cleaning agent condensation fluid power in the condensate tank(trap) successfully to be transferred to circulating slot; Also include circulating pump and threeway, said circulating slot and circulating pump, threeway form closed circuit, said threeway one end communication loop pump; One end communication loop groove, the other end is communicated with condensate tank(trap).Abundant for the condensation that further guarantees cleaning agent volatilization composition, between said condensate tank(trap) and distillation tank, also be provided with heat exchanger, said cooler and condensate tank(trap), heat exchanger also form a cooling circuit.
Therefore, in sum, that distillation recovery system of the present invention has is simple in structure, energy utilizes high, cleaning advantage easily.
