Compared with the general ammonia refrigerating, the novel ammonia refrigerating device is used as a cold storage, and is added with the heat source utilization and the pressure control flow of the ammonia-liquid separator so that the technology reduces the power consumption and the device investment, and meets different temperature generation demands.
Description
One, technical field: the present invention relates to a kind of ammonia refrigeration technology, especially a kind of novel ammonia refrigerating installation and technological process.
Two, background technology: ammonia refrigeration system generally is used for refrigeration, the freeze preservation of freezing processing and food, provides cold by the choke valve throttling, and is less to the control of liquefied ammonia temperature; Be exactly that ammonia compressor outlet thermal source does not utilize in addition, directly be recycled cooling water and take away and waste.
Three, summary of the invention: the purpose of this invention is to provide a kind of novel ammonia refrigerating installation and technological process.It has solved, and medium temperature is controlled within the specific limits and control range is less, the problem that the temperature change hysteresis is wayward and the ammonia compressor thermal source utilizes, the object of the present invention is achieved like this, its device is by ammonia compressor, gs-oil separator, dielectric heater, ammonia condenser, temperature control valve, the ammonia reservoir, choke valve, ammonia liquor separator, pressure-regulating valve, the cooling evaporimeter, flowmeter and temperature control valve (TCV) are formed by connecting, the ammonia compressor port of export links to each other with pipeline with the gs-oil separator arrival end, the gs-oil separator port of export links to each other with pipeline with the ammonia condenser arrival end with the dielectric heater arrival end respectively, and temperature control valve wherein is installed in the middle of the gs-oil separator port of export and the dielectric heater arrival end; The dielectric heater port of export and the ammonia condenser port of export converge, and the dielectric heater port of export is equipped with flowmeter, and the dielectric heater port of export links to each other with pipeline with ammonia reservoir arrival end with ammonia condenser port of export meet; The ammonia reservoir port of export links to each other with pipeline with the ammonia liquor separator arrival end, and the centre is equipped with choke valve; Ammonia liquor separator gaseous phase outlet end links to each other with pipeline with the ammonia compressor inlet, and the centre is equipped with pressure-regulating valve; The ammonia liquor separator bottom liquid phases port of export links to each other with pipeline with cooling evaporator inlet end, and the centre is equipped with temperature control valve (TCV).
Technological process is: the gas phase of HTHP comes out to enter gs-oil separator separating oil component from ammonia compressor, enter dielectric heater and ammonia condenser then respectively, enter the temperature that the hot ammonia flow of dielectric heater is regulated institute's heat medium through temperature control valve control, produce needs to satisfy; Hot ammonia converges after by dielectric heater and ammonia condenser cooling condensation and enters the ammonia reservoir, enters ammonia liquor separator through choke valve throttling cooling again; Ammonia liquor separator gas phase part enters the ammonia compressor inlet through pressure-control valve, and the ammonia liquor separator liquid phase part enters the working solution medium that the cooling evaporimeter comes in order to cooling device by temperature control valve, and the evaporation gas phase is returned ammonia liquor separator, so circulation.
Meaning of the present invention: in order to make full use of ammonia refrigeration system, when design, change general ammonia refrigeration system technological process, promptly increase by two special applications in addition: the one, the ammonia liquor separator gaseous phase outlet will carry out the control of ammonia liquor separator pressure before advancing ammonia compressor; The 2nd, the ammonia compressor outlet increases thermal source and uses.Because temperature change lags behind, can be according to different medium temperature control requirements, corresponding relation according to macroscopic property pressure and temperature under the ammonia working medium saturation state, the pressure of ammonia liquor separator is also made corresponding change, this technology and former temperature control valve work along both lines can better controlled the medium temperature of institute's chilling requirement, change pressure ratio and change temperature effect and come soon; Another has reduced energy consumption at the thermal source utilization, and corresponding ammonia condenser thermic load reduces, and has reduced equipment investment.
Four, description of drawings: Fig. 1 is novel ammonia refrigerating installation structural representation, among the figure 1, ammonia compressor 2, gs-oil separator 3, dielectric heater 4, ammonia condenser 5, temperature control valve 6, ammonia reservoir 7, choke valve 8, ammonia liquor separator 9, pressure-regulating valve 10, cooling evaporimeter 11, flowmeter 12, temperature control valve (TCV)
Five, the specific embodiment: in Fig. 1, ammonia compressor 1 port of export links to each other with pipeline with gs-oil separator 2 arrival ends, gs-oil separator 2 ports of export link to each other with pipeline with ammonia condenser 4 arrival ends with dielectric heater 3 arrival ends respectively, and temperature control valve 5 wherein is installed in the middle of gs-oil separator 2 ports of export and dielectric heater 3 arrival ends; Dielectric heater 3 ports of export and ammonia condenser 4 ports of export converge, and dielectric heater 3 ports of export are equipped with flowmeter 11, dielectric heater 3 ports of export link to each other with pipeline with ammonia reservoir 6 arrival ends with ammonia condenser 4 port of export meets: ammonia reservoir 6 ports of export link to each other with pipeline with ammonia liquor separator 8 arrival ends, and the centre is equipped with choke valve 7; Ammonia liquor separator 8 gaseous phase outlet ends link to each other with pipeline with ammonia compressor 1 inlet, and the centre is equipped with pressure-regulating valve 9; The ammonia liquor separator 8 bottom liquid phases ports of export link to each other with pipeline with cooling evaporimeter 10 arrival ends, and the centre is equipped with temperature control valve (TCV) 12.
Technological process is: the gas phase of HTHP comes out to enter gs-oil separator 2 separating oil components from ammonia compressor 1, enter dielectric heater 3 and ammonia condenser 4 then respectively, enter the temperature that the hot ammonia flow of dielectric heater is regulated institute's heat medium through temperature control valve 5 control, produce needs to satisfy.
Hot ammonia converges after by the 4 cooling condensations of dielectric heater 3 and ammonia condenser and enters ammonia reservoir 6, enters ammonia liquor separator 8 through choke valve 7 throttlings cooling again.
