Abstract
The utility model discloses a device for drying and concentrating solution in vacuum, aiming to provide a device for drying and concentrating the solution by evaporating water in the solution through a combined action of vacuum and a low-temperature hot source, so as to achieve the purposes of reducing energy consumption and saving energy. The device comprises a concentrating container; the concentrating container is provided with a dilute solution inlet and a concentrated solution outlet; the concentrating container is connected with a vacuum pump, a pressure gage and a decompression valve; and the concentrating container is internally provided with a low-temperature heat source heater. According to the device for drying and concentrating the solution in vacuum provided by the utility model, based on a principle that the water in a vacuum state is easy to evaporate at a low temperature, the solution is dried and concentrated by evaporation of the water in the solution through the combined action of the vacuum and the low-temperature hot source, so as to achieve the purposes of reducing the energy consumption and saving the energy.
Description
Technical field
The utility model relates to the dry enrichment facility of a kind of solution for vacuum.
Background technology
In solution dehumidifying air-conditioning system, the later concentration of salt solution of moisture absorption diminishes, and needs to regain wettability power through concentration, carries out air dewetting with circulation.The process that concentrates, regains wettability power of hygroscopic solution can be described as the regenerative process of solution, and this process is separated the portion of water in the salting liquid essentially exactly from solution.Can be known that by Engineering Thermodynamics dissolution phenomena is an irreversible procedure, realize from mixture, separating pure substance needs consumes energy, and method commonly used is to use the normal pressure heating vaporization that common dry enrichment facility is realized on the engineering.Normal pressure heating requirements heat hot source temperature is higher, and because the salting liquid temperature is very big to its moisture pick-up properties influence, must be cooled to normal temperature to the hot solution after the regeneration dehumidification process is adhered to specification.Therefore, the regeneration of salting liquid all is to go out moisture through the higher temperature heating evaporation at present, weak solution is concentrated obtain concentrated solution, dehumidifies delivering to dehumidifier again after the concentrated solution cooling again.This sensible heat change procedure is with the system resources such as time, space and energy of labor, and system architecture is complicated.
The utility model content
The utility model is in order to overcome weak point of the prior art, a kind of acting in conjunction through vacuum and low-temperature heat source to be provided, the moisture in the evaporating liquid; Realize the concentrated device of drying of solution; To cut down the consumption of energy, reach purpose of energy saving, be applicable to the regeneration of solution.
The utility model is realized through following technical proposals:
The dry enrichment facility of a kind of solution for vacuum; It is characterized in that, comprise concentrate container, said concentrate container is provided with dilute solution inlet, concentrated solution outlet; Be connected with vavuum pump, Pressure gauge and relief valve on the said concentrate container, said concentrate container inside is equipped with the low-temperature heat source heater.
Said low-temperature heat source heater employing temperature is 45-60 ℃ a low-temperature heat source.
The utlity model has following technique effect:
1, the dry enrichment facility of the solution for vacuum of the utility model is prone to the principle of evaporation at low temperatures based on moisture under the vacuum state, and through the acting in conjunction of vacuum and low-temperature heat source, the moisture in the evaporating liquid realizes that the drying of solution concentrates.Reduced heat source temperature, reduced energy consumption, the energy-conservation energy.
When 2, the dry enrichment facility of the solution for vacuum of the utility model is used for the regeneration of solution, avoid the process of cooling again that heats up, practiced thrift system resource, simplified system architecture.
Description of drawings
Fig. 1 is the sketch map of the dry enrichment facility of the utility model solution for vacuum.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Fig. 1 is the sketch map of the dry enrichment facility of the utility model solution for vacuum; Comprise concentrate container 3; Said concentrate container 3 is provided with dilute solution inlet 2, concentrated solution outlet 4; Be connected with vavuum pump 5, Pressure gauge 6 and relief valve 7 on the said concentrate container 3, said concentrate container inside is equipped with low-temperature heat source heater 1.Said low-temperature heat source heater employing temperature is 45-60 ℃ a low-temperature heat source.
Earlier concentrate container is vacuumized, when meeting the requirements of vacuum weak solution is put into, under vacuum state, the water evaporates in the concentrate container makes weak solution become suitable concentrated solution.Because water evaporates will be taken away heat, solution temperature is reduced, in order to accelerate the evaporation of moisture, keep solution temperature simultaneously, utilize low-temperature heat source heater heated solution.Weak solution is closed weak solution feed liquor valve after becoming concentrated solution, opens relief valve and makes concentrate container return to normal pressure, opens the concentrated solution outlet valve, and concentrated solution gets into the sump assemblies of concentrated solution, accomplishes the dry concentration process of solution.
