Abstract
The utility model provides a novel vacuum distillation system design. Gas at a top of a distillation tower is condensed through a condenser; crude alcohol enters a temporary storage tank; gas which is not condensed is brought to the temporary storage tank through an ejector taking the crude alcohol as a circulation medium, and then is condensed again; noncondensable gas is exhausted into the atmosphere; the crude alcohol in the temporary storage tank is ejected out through a high-pressure circulating pump, is condensed by a condenser and enters the ejector; the crude alcohol is ejected at a high speed through a spray nozzle under high pressure; low pressure is produced in a mixing chamber; the gas is sucked into the mixing chamber by a conveying liquid and is mixed with condensed crude alcohol; most of the gas is condensed into a liquid, a small amount of the gas which is not condensed and the crude alcohol enter an amplifying pipe together; when passing through the amplifying pipe, pressure of the liquid gradually rises; and the gas enters the temporary storage tank with the crude alcohol and then is exhausted. In the whole process, the crude alcohol is taken as the circulation medium of the vacuum injection pump, so that vacuum is formed in the distillation crude tower.
Description
Technical field
The utility model relates to the material vacuum distillation equipment in a kind of alcohol industry, relates in particular to a kind of material vacuum distillation equipment of applying the airless injection system.
Background technology
Along with China's fast economic growth, every construction has all obtained great achievement, but also paid huge resources and environment cost, the contradiction of economic development and resource environment is increasingly sharp-pointed, further strengthening energy-saving and emission-reduction work, is all social responsibilities of enterprises, and energy-saving and emission-reduction are gone in group with enterprise, not only can bring social benefit to enterprise, also can increase the economic benefit of enterprise simultaneously.What the vacuum distillation apparatus of current domestic most alcohol enterprise adopted is nearly all that water-ring vacuum pump vacuumizes, and in thick wine still-process, can cause alcohol losses significantly, needs to consume a large amount of fresh waters, has produced again a large amount of waste water simultaneously.
The utility model content
In the alcohol vacuum distillation process, thick wine, as the airless injection system of medium, has been saved the energy consumption of pumped vacuum systems greatly, reduced the discharge of waste water, lowered the loss of alcohol in the still-process, when increasing economic efficiency, played a role in energy saving.Ripe wine with dregs is removed involatile substance through thick column distillation, and the ethanol that tower top is separated and the mixture of contained volatile impurity are thick wine.
The utility model provides a kind of alcohol material vacuum distillation equipment, comprises destilling tower (1), condenser (2), temporary tank (3), vacuum ejector (4), high-pressure circulation pump (5), plate type heat exchanger (6), filter (7), wherein, described vacuum ejector (4) comprises, liquid chamber (41), nozzle (42), mixing chamber (43) and trunnion (44), enlarged tube (45), air entry (46), outlet (47), liquid inlet (48); In thick wine vacuum distillation process, by described vacuum ejector, make to distill thick tower and form vacuum.
In a preferred embodiment, in described thick wine vacuum distillation process, utilize thick wine as ejection medium, become the vacuum source of the thick tower of distillation.
Destilling tower (1) top vapour (thick wine vapour) is through condenser (2) condensation, thick wine enters into temporary tank (3), uncooled gas is brought in temporary tank and again carries out condensation by take vacuum ejector (4) that thick wine is circulatory mediator, and fixed gas is disposed in atmosphere.Vacuum ejector (4) course of work is, thick wine is got through high-pressure circulation pump (5) in temporary tank (3), enter vacuum ejector (4) after plate type heat exchanger (6) cooling, thick wine under high pressure passes through nozzle (42) while at full speed penetrating, produce low pressure in mixing chamber, the fluid that gas is transferred sucks mixing chamber (43), mixed mutually with condensed thick wine, most of gas cold liquid that congeals into, a small amount of uncooled gas together enters enlarged tube (45) with thick wine, through enlarged tube (45) time, the pressure of fluid rises again gradually, gas is discharged after entering temporary tank with thick wine.In overall process, thick wine, as the vacuum jet pump circulatory mediator, makes to distill thick tower and forms vacuum.
Useful technique effect of the present utility model is, with the water ring vacuum pump pumped vacuum systems, compares, and the present invention has following advantage:
When 1, saving the fresh water consumption, reduce discharge of wastewater, reduced the cost of sewage disposal, in energy-saving and emission-reduction, increased enterprise income.
2, thick wine, as circulatory mediator, reduces the loss of alcohol in still-process, has improved economic benefit.
3, increased filter in the device, thick wine from temporary tank out, enters injector via filter, prevents that the small part material that thick wine carries from causing injector nozzle to stop up.
The accompanying drawing explanation:
Fig. 1 is: alcohol material vacuum distillation equipment schematic diagram of the present utility model;
Fig. 2 is: the schematic diagram of vacuum ejector.
The specific embodiment
In order more clearly to understand the purpose of this utility model, technical scheme and beneficial effect, below by specific embodiment, the utility model is described further.
As shown in Figure 1, the top vapour of destilling tower (1) carries out condensation through condenser (2), and thick wine enters into temporary tank (3), and uncooled gas is by take the vacuum ejector (4) that thick wine is circulatory mediator, be brought in temporary tank (3) and again carry out condensation, fixed gas is disposed in atmosphere.Thick wine, in temporary tank (3), is got by high-pressure circulation pump (5), after plate type heat exchanger (6) condensation, enters vacuum ejector (4).In injector (4), as shown in Figure 2, thick wine is by liquid inlet
enter liquid chamber (41), under high pressure pass through nozzle (42) while at full speed penetrating, produce low pressure in mixing chamber (43) and trunnion (44), the fluid that gas is transferred brings mixing chamber (43) into by air entry (46) and trunnion (44) is mixed mutually with condensed thick wine, most of gas cold liquid that congeals into, a small amount of uncooled gas together enters enlarged tube (45) with thick wine.Through enlarged tube (45) time, the pressure of fluid rises again gradually, and gas is discharged after outlet (47) enters temporary tank (3) with thick wine.In overall process, thick wine, as the vacuum jet pump circulatory mediator, makes to distill thick tower and forms vacuum.Basic conception of the present utility model is: by increasing vacuum jet pump, utilize thick wine as ejection medium, become the vacuum source of the thick tower of distillation.Reduce energy consumption when meeting process requirements.
Through calculating equipment of the present utility model, to increase economic benefit obvious: fresh water: jet pump than water ring vacuum pump few consume 5 tons, water/time; Wastewater flow rate: jet pump than water ring vacuum pump few produce 5 tons of waste water/time, reduce sewage disposal; Alcohol output: jet pump than water ring vacuum pump few lose 14.5 kilograms of alcohol/time.
Above-described embodiment is the utility model embodiment preferably; but embodiment of the present utility model does not accept to appeal the restriction of embodiment; other any do not deviate from the change of doing, modification under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent displacement and prevent, within being included in protection domain of the present utility model.
