An ammonia gas detection sensor is fixed to the cooling evaporator and used for detecting leaking ammonia gas, and therefore running safety of the device is ensured. The ammonia-liquid separator is reasonable in structural design, ammonia oil, water and the like which are carried in the normal ammonia refrigeration process can be effectively evaporated, and the phenomenon that ammonia is carried by an ice maker in the normal working process can be effectively avoided.
Description
Technical field
The invention belongs to refrigeration technology field, relate to a kind of for ammonia refrigeration system, be specifically related to a kind of intelligent ammonia refrigerating installation for agricultural byproducts.
Background technology
Ammonia refrigeration system forms primarily of compressor, condenser, storage ammonia device, oil eliminator, choke valve, ammonia liquor separator, evaporimeter, intercooler, emergency ammonia drainer, oil catcher, various valve, Pressure gauge and high-low pressure pipeline.Wherein, the compressor in refrigeration system, condenser, choke valve and evaporimeter freezer comb are four most basic elements of character.Connect successively with pipeline between them, form a closed system, cold-producing medium ammonia constantly circulates in systems in which, generation state changes, exchange heat is carried out with the external world, its course of work is: after liquid ammonia absorbs the heat of cooled object in evaporimeter, be vaporized into the ammonia of low-pressure low-temperature, sucked by compressor, enter condenser after being compressed into the ammonia of high pressure-temperature, cooled water for cooling exothermic condensation is high pressure ammoniacal liquor within the condenser, is the ammoniacal liquor of low-temp low-pressure through choke valve throttling, again enter evaporimeter endothermic gasification, reach the object of circularly cooling.
The concentration having toxicity due to ammonia and gather in space has potential explosion danger when acquiring a certain degree, and makes it when using as cold-producing medium, and its application scenario is restricted and is mainly used in huge industrial refrigeration and commercial freezer refrigeration field; Simultaneously, because the vapor pressure of liquefied ammonia is very large, if evaporimeter produces pore or crack, ammonia can be revealed rapidly, and in freezer, the fresh fruits and vegetables of storage are exposed in ammonia environment for a long time, can rot very soon, and because freezer is closed area, after ammonia is revealed, freezer management personnel can not find at once, and therefore to reveal the loss caused very large due to ammonia for some freezers.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of energy-conservation, operating cost is low and the intelligent ammonia refrigerating installation for agricultural byproducts of safety.
For solving the problems of the technologies described above, a kind of intelligent ammonia refrigerating installation for agricultural byproducts of the present invention, be formed by connecting by ammonia compressor, gs-oil separator, dielectric heater, ammonia condenser, temperature control valve, ammonia reservoir, choke valve, ammonia liquor separator, pressure-regulating valve, cooling evaporator and temperature control valve (TCV), the described ammonia compressor port of export is connected with gs-oil separator arrival end pipeline, the dielectric heater port of export and the ammonia condenser port of export converge, the port of export of ammonia liquor separator is connected with ammonia compressor entrance pipeline, and centre is provided with pressure-regulating valve; Described cooling evaporator is installed with ammonia detecting sensor, ammonia detecting sensor is connected with controller, and controller also connects warning device.
Gas outlet and liquid outlet is respectively equipped with at the two ends up and down of above-mentioned ammonia liquor separator, air inlet and inlet are arranged on the sidewall of ammonia liquor separator, and the liquid level of described air inlet in ammonia liquor separator is lower than gas outlet, the liquid level of liquid outlet in ammonia liquor separator is lower than inlet, gas equalizing line is positioned on the sidewall of ammonia liquor separator, fuel outlet is arranged on the bottom of ammonia liquor separator, is provided with safety valve on the top of ammonia liquor separator.
Compared with prior art, beneficial effect of the present invention is:
The present invention fixedly mounts ammonia detecting sensor on cooling evaporator, for detecting the ammonia of leakage, thus guarantee equipment security of operation.
The present invention can according to different medium temperature control overflow, and according to the corresponding relation of macroscopic property pressure and temperature under ammonia working medium saturation state, thermal source utilizes and reduces energy consumption, and corresponding ammonia condenser thermic load reduces, and decreases equipment investment.
The tectonic sieving of ammonia liquor separator of the present invention is reasonable, the liquid level of air inlet in ammonia liquor separator lower than liquid level in ammonia liquor separator of gas outlet, liquid outlet lower than inlet, effectively can evaporate the ammonia oil, water etc. carried secretly in normal ammonia refrigeration technique, the phenomenon with ammonia in can effectively avoiding ice maker normally to work.
