Description

Dissolution refrigeration circulation device
Technical field
The present invention relates to a kind of dissolution refrigeration circulation device, mainly rely on the dissolving of material to produce cold.
Background technology
Known to the inventor, in existing refrigerating plant, mainly form as compressing refrigeration cycle apparatus by compressor, evaporimeter, condenser, throttling arrangement etc., it does cycle fluid (cold-producing medium) with hydrocarbon or ammonia etc., relies on the evaporation of working medium in evaporimeter to absorb heat and produces refrigeration effect.The outlet of evaporimeter links to each other with the import of compressor, the steam that produces in the evaporimeter makes its condensation by compressor compresses, the outlet of compressor connects the import of condenser, steam is sent to and is condensed into liquid in the condenser, condensed liquid enters throttling arrangement by the throttling arrangement import that is attached thereto and the pipeline of condensator outlet, the outlet of throttling arrangement connects the import of evaporimeter, liquid working substance is sweat cooling in evaporimeter, swabbing action by compressor is drawn into the steam that produces in the compressor simultaneously, thereby realizes continuous kind of refrigeration cycle.This device refrigerating capacity is big, but generally to the sealing requirements height, and can only can not utilize low grade residual heat with Mechanical Driven or the work of electric power drive compression machine.
Summary of the invention
The purpose of this invention is to provide a kind of dissolution refrigeration circulation device, it can utilize waste heat to freeze, and remedies the above-mentioned deficiency of prior art.
A kind of dissolution refrigeration circulation device is characterized in that having a dissolving refrigerator, and its top inlet is communicated with the outlet of choke valve, and another import is communicated with the outlet of heat exchanger, and the outlet of bottom is communicated with inlet of circulating pump; The import of evaporation and concentrating device is communicated with outlet of circulating pump by pipeline, and the top outlet is communicated with the import of stram condenser, and the outlet of side-lower is communicated with the import of heat exchanger; The outlet of described stram condenser is communicated with the import of choke valve.
Advantage of the present invention is not need high sealing in the circulation, can utilize engine exhaust heat or industrial exhaust heat to be used as thermal source, and is simple to operation, stable.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
This dissolution refrigeration circulation device is that a dissolving refrigerator 3 is arranged, and its top inlet is communicated with the outlet of choke valve 2, and another import is communicated with the outlet of heat exchanger 5, and the outlet of bottom is communicated with the import of circulating pump 4; An import of evaporation and concentrating device 6 is communicated with by the outlet of pipeline with circulating pump 4, and the top outlet is communicated with the import of stram condenser 1, and the outlet of side-lower is communicated with the import of heat exchanger 5; The outlet of described stram condenser 1 is communicated with the import of choke valve 2.
Dissolving refrigerator 3 in this device is existing sieve-plate tower, just its inner not perforate of baffle plate, this sieve-plate tower bottom is a heat exchanger, and chilled water is taken out of through the cold that this heat exchanger will dissolve in the refrigerator 3, and saturated solution is drawn by the bottom after finishing heat exchange and entered evaporation and concentrating device 6.
The present invention adopts nitrate (as potassium nitrate (KNO 3), silver nitrate (AgNO 3)) or bromate (as ammonia bromide (NH 4Br)) wait some materials that in course of dissolution, can produce cold as working medium, the dissolution of crystals in the supersaturated solution is produced cold by adding water.When supersaturated solution mixes with water, will produce cold in the course of dissolution of solute crystals will, solution improves the concentration of solution through after the heat exchange by evaporation and concentrating device 6, thereby realizes the continuous cycle operation of this device.
When device of the present invention operates, the pipeline of the entrance point of the saturated potassium nitrate solution of high temperature that is come out by evaporation and concentrating device 6 outlet at bottoms by connecting evaporation and concentrating device 6 and heat exchanger 5 enters in the heat exchanger 5, potassium nitrate solution is walked in the pipe in heat exchanger 5, by the temperature of solution being descended with the outer condensed water heat exchange of flowing through of pipe, form the supersaturation potassium nitrate solution, from solution, separate out potassium nitrate crystals simultaneously; Oversaturated potassium nitrate solution mixes with the water that flows out from the outlet of choke valve 2 with the top that the pipeline of dissolving refrigerator 3 imports enters dissolving refrigerator 3 by the outlet that connects heat exchanger 5, potassium nitrate crystals dissolving in the process of mixing, form saturated potassium nitrate solution, produce the output of cold simultaneously; The saturated solution that produces is drawn from the bottom of dissolving refrigerator 3, is sent in the evaporation and concentrating device 6 back to heating by the pressurization of circulating pump 4 and carries dense; The steam that evaporates in the evaporation and concentrating device 6 is drawn by the top, enter in the stram condenser 1 by the pipeline that connects evaporation and concentrating device 6 tops and stram condenser 1 import, the water that condenses enters choke valve 2, decrease temperature and pressure through choke valve 2, outlet by connecting choke valve 2 and the pipeline of the import of dissolving refrigerator 3 enter in the dissolving refrigerator 3 with the supersaturated solution of coming in the heat exchanger 5 and mix, thus the circulation of realization package unit.
