Background technology
Closed cycle pipeline or open circulation pipeline often need to control stable temperature.In prior art, be the temperature of rising circulation line, usually steam be directly filled with to circulation line or with the direct Heating Cyclic pipeline of electrical heating method medium; For reducing the temperature of circulation line, usually cold water is directly filled with to circulation line or only uses a heat exchanger and circulation line medium carries out cold and hot exchange.Prior art causes circulation line control temperature deviation large, and control range precision is low; Due to circulation line medium and steam or cold water mix, cause mutual pollution; If particularly its medium reverse flow enters cold water source in circulation line temperature-rise period, can cause heat too much to run off.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide one can avoid circulation line temperature to cross great fluctuation process, control range precision is high, the free of contamination a kind of double heat exchanger temperature control system of temperature control medium.
The utility model solves the technical scheme that its technical problem adopts: this double heat exchanger temperature control system, comprise the container that chuck is housed, circulation line is housed on chuck, in chuck and circulation line, circulatory mediator is housed, it is characterized in that: on described circulation line, be respectively equipped with separate hot heat exchanger and cold conditions heat exchanger; Hot heat exchanger connects heat supplying pipeline, and cold conditions heat exchanger connects refrigeration pipe; On heat supplying pipeline and refrigeration pipe, valve is housed.
Described heat supplying pipeline is the pipeline of steam heating, heat supplying pipeline comprises that steam that heating agent enters hot heat exchanger enters pipeline and heating agent and flow out the condensate return pipeline of hot heat exchanger, steam enters on pipeline steam valve is set, and on condensate return pipeline, drain valve is set.
Described refrigeration pipe is water-cooled pipeline, and refrigeration pipe comprises that cold water that refrigerant enters cold conditions heat exchanger enters pipeline and refrigerant and flow out the cold-water reflux pipeline of cold conditions heat exchanger, and cold water enters cold valves is set on pipeline.
One circulating pump also can be set on described circulation line, make circulatory mediator forced flow in external pipe and chuck.
In the utility model, circulation line and heat supplying pipeline, refrigeration pipe independence controlling run, heat supplying pipeline, refrigeration pipe have respectively independent external tapping.
In the utility model, heat supplying pipeline has by steam valve controlling run, refrigeration pipe by cold valves controlling run.
Double heat exchanger temperature control system described in the utility model, compact conformation, multiple functional, guaranteed the temperature stability in circulation line, prevented that interior media heat excessively runs off, greatly reduce the possibility that medium pollutes mutually, improved processing safety.
Heat supplying pipeline steam medium is not communicated with circulation line medium.Refrigeration pipe cold water medium is not communicated with circulation line medium.Heat supplying pipeline steam medium is not communicated with refrigeration pipe cold water medium.
Compared with prior art, the beneficial effect that double heat exchanger temperature control system of the present utility model has is: the utility model is opened by control or steam off valve and cold valves, and double heat exchanger temperature control system can maintain the temperature of system automatically in the allowed band of setting value.Even if heating steam or refrigeration water occurrence temperature change, also can keep the stable of circulation line temperature.Heat supplying pipeline, refrigeration pipe and circulation line are separate, and double heat exchanger is respectively used to heat supply and refrigeration, have avoided hot steam, cold conditions water to mix with medium in circulation line the pollution causing.
Accompanying drawing explanation
Fig. 1 is the structural representation of double heat exchanger temperature control system.
Wherein: 1, hot heat exchanger 2, cold conditions heat exchanger 3, cold valves 4, steam valve 5, circulation line 6, drain valve 7, heat supplying pipeline 8, refrigeration pipe 9, container.
Fig. 1 is the most preferred embodiment of the utility model double heat exchanger temperature control system, below in conjunction with accompanying drawing 1, the utility model is described further.
The specific embodiment
With reference to accompanying drawing 1: double heat exchanger temperature control system of the present utility model, comprise hot heat exchanger 1, cold conditions heat exchanger 2, cold valves 3, steam valve 4, circulation line 5, drain valve 6, heat supplying pipeline 7, refrigeration pipe 8, container 9, circulation line 5 is housed on the chuck of container 9, in chuck and circulation line 5, circulatory mediator is housed, on circulation line 5, is provided with hot heat exchanger 1 and cold conditions heat exchanger 2 and forms double heat exchanger.On hot heat exchanger 1, connect heat supplying pipeline 7, on cold conditions heat exchanger 2, connect refrigeration pipe 8.The pipeline that heat supplying pipeline 7 is steam heating, heat supplying pipeline 7 comprises that steam that heating agent enters hot heat exchanger 1 enters pipeline and heating agent and flow out the condensate return pipeline of hot heat exchanger 1, steam enters on pipeline steam valve 4 is set, and drain valve 6 is set on condensate return pipeline.Refrigeration pipe 8 is water-cooled pipeline, and refrigeration pipe 8 comprises that cold water that refrigerant enters cold conditions heat exchanger 2 enters pipeline and refrigerant and flow out the cold-water reflux pipeline of cold conditions heat exchanger 2, and cold water enters cold valves 3 is set on pipeline.
Double heat exchanger temperature control system is established six external tappings, and wherein double heat exchanger is established circulation line 5 imports and answered back, and heat supplying pipeline 7 establishes steam inlet and condensed water is answered back, and refrigeration pipe 8 establishes cooling water inlet and cold water is answered back.
Operation principle: double heat exchanger temperature control system of the present utility model presets after the operating temperature of circulation line 5, accesses its six external tapping successively respectively circulation line 5, vapour source and condensed water receiving system, cold water source import and answers back.
