for ammonia walk-in cooler gas-liquid separator
for ammonia walk-in cooler gas-liquid separator, or ammonia separator. The ammonia liquid separator is an important auxiliary equipment in the ammonia gravity liquid supply system. Its function is: one is to separate the ammonia droplets contained in the return gas from the evaporator, and then be sucked by the compressor to prevent the compressor from wet stroke; the other is the high-pressure ammonia from the reservoir The flash gas produced by the throttling and pressure reduction of the liquid through the throttle valve can be separated in the ammonia liquid separator to prevent the flash gas from entering the evaporator, so as to give full play to the heat exchange effect of the heat transfer surface of the evaporator, and at the same time Ensure even liquid supply to the evaporator. The working principle of the gas-liquid separator for ammonia is as follows: the large amount of gas produced by the boiling of ammonia in the evaporator moves in the evaporation tube at a high speed of 8~12m/s under the suction action of the compressor, resulting in some unevaporated ammonia droplets Carried out with ammonia. When these ammonia gas (return gas) enters the ammonia gas-liquid separator, the cross section of the channel suddenly expands 4 to 5 times, the flow rate is reduced to about 0.5m/s, and the flow direction changes, so that the denser ammonia droplets are removed from the ammonia gas. Separated from the water and deposited under the container, while the ammonia gas is sucked back by the compressor. The separated ammonia can be sent back to the walk-in cooler evaporator for evaporation. Different vaporization temperatures should be equipped with gas-liquid separators for ammonia. The gas-liquid separator for ammonia is a low-temperature container and should be covered with an insulating layer.
