Accompanying drawing explanation
Fig. 1 is the structured flowchart of thermal siphon screw type cold compressibility described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the utility model thermal siphon screw type cold compressibility, comprise ammonia cooler 1, evaporative condenser 2, thermal siphon liquid reservoir 3, thermal siphon oil cooler 4, thermal siphon screw type refrigerating compressor 5, ammonia tank 6 and water replanishing device 7, the liquefied ammonia outlet of evaporative condenser 2 is connected with the liquefied ammonia entrance of thermal siphon liquid reservoir 3, the liquefied ammonia outlet of thermal siphon liquid reservoir 3 is connected with the feed pipe of thermal siphon oil cooler 4, the muffler of thermal siphon oil cooler 4 is connected with the gas-liquid mixed ammonia entrance of thermal siphon liquid reservoir 3, the gas ammonia outlet of thermal siphon liquid reservoir 3 is connected with the gas ammonia entrance of evaporative condenser 2, the air inlet of thermal siphon screw type refrigerating compressor 5 exports with the gas ammonia of ammonia cooler 1 and is connected, the gas outlet of thermal siphon screw type refrigerating compressor 5 is connected with the gas ammonia entrance of evaporative condenser 2, the ammon entry hole of ammonia tank 6 is connected with the overfall of thermal siphon liquid reservoir 3, the delivery port of water replanishing device 7 is connected with the water inlet of evaporative condenser 2, the number of evaporative condenser 2 is multiple.
The operation principle of the utility model thermal siphon screw type cold compressibility is as follows:
The ammonia cooler 1 of synthetic ammonia steams the gas ammonia (0.16Mpa ~ 0.23Mpa (gauge pressure)) of discharging out after thermal siphon screw type refrigerating compressor 5 pressurizes (≤1.6Mpa (gauge pressure)), enters evaporative condenser 2 and cools.
After evaporative condenser 2 condensed liquefied ammonia inflow thermal siphon liquid reservoir 3, distribute a part of liquefied ammonia enter thermal siphon oil cooler 4, absorb thermal siphon have the heat of the high temperature oil outside the heat exchanger tube in cooler and be evaporated to gas-liquid mixed ammonia, liquefied ammonia reduces gradually at evaporation process Midst density, the density of the gas-liquid mixture in thermal siphon oil cooler 4 muffler will lower than the density of liquefied ammonia in thermal siphon oil cooler 4 feed pipe, this density contrast just generates a pressure differential, liquefied ammonia is constantly flowed in oil cooler, the continuous heat absorbing oil, realizes the cooling of oil.
Thermal siphon oil cooling is but a kind of mode of the indirect cutting oil of exhaust end base of oil injection threaded bolt formula refrigeration compressor, different from water cooling lubricating oil mode, and it relies on the evaporative cooling lubricating oil of cold-producing medium, the thermic load of cold oil is transferred in condenser.
Wherein, thermal siphon liquid reservoir 3 is also utilize siphon principle, gas-liquid mixed ammonia in thermal siphon oil cooler 4 is drawn in thermal siphon liquid reservoir 3 and is separated, gas ammonia after separation converges by the gas ammonia after siphonage and thermal siphon screw type refrigerating compressor 5 pressurize and enters evaporative condenser 2, and unnecessary liquefied ammonia is stored from overfall inflow ammonia tank 6.
Thermal siphon oil cooling system and water-cooling type oil cooling system contrast, compact conformation, refrigerating capacity is large, conventional operating mode (entry/exit oil temperature is: 85/50 DEG C, condensation temperature: 40 DEG C), recirculated cooling water (inlet/outlet temperature is: 35/25 DEG C) is compared, and " temperature difference " of thermal siphon liquid reservoir 3 is large, and the efficiency of cooling is just large than water-cooled oil cooling machine, therefore heat exchange area can significantly reduce, and area occupied is little.
Oil cooling is but relatively reliable, and rely on siphonage, system is normally run it and just run, and save the equipment such as a large amount of water pumps, cooling tower, wasted work is few, economical operation, also saves a large amount of installation cost and regular maintenance expense.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion made according to the technical solution of the utility model, all falls within protection domain of the present utility model.
