Multiple apertures are offered in the indoor pipeline section top wall surface of gas-liquid contact；There is spiral shape natural gas tube in the inside for crossing cold house
Road, the side for crossing cold house set through-pore and pass through the natural gas inlet pipe that is separately connected with spiral shape natural gas line and naturally
Gas outlet pipe, bottom have one end of through-pore and supercooled liquid return pipe to weld, the other end and gas-liquid of the supercooled liquid return pipe
The another side bottom through-pore of contact chamber welds, and the supercooled liquid return pipe medial fascicle and supercooled liquid are in charge of welding；Institute
The position being fitted and connected on face close to top stated gas-liquid contact room and cross cold house has through the gas-liquid contact room and crosses cold house
The by-pass port of connection.
Bracket is respectively welded in the gas-liquid contact room and the bottom for crossing cold house.
The gas-liquid contact room is closed hollow square body structure.
The cold house of crossing is closed hollow square body structure.
The height of the gas-liquid contact room was greater than the height of cold house.
The natural gas waste cold supercooling of the utility model and directly contact condensation heat transfer equipment, utilize natural gas transportation process
Gasify waste cold, and refrigerant liquid is subcooled, and high-temperature high-pressure refrigerant gas and supercooled liquid direct contact heat transfer condense, and reduces heat transfer
The temperature difference, refrigeration compressor pressure ratio reduce, and wasted work is reduced, and the performance of refrigeration system improves.
In addition, the utility model economizes on resources by the waste cold of sufficiently recycling natural gas, protects environment.
Detailed description of the invention
Fig. 1 show the supercooling of natural gas waste cold and the schematic diagram of directly contact condensation heat transfer equipment of the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the supercooling of natural gas waste cold and directly contact condensation heat transfer equipment, comprising:

Liquid return pipe 7, high-temperature gas pipe 8.
The gas-liquid contact room 1 is closed hollow square body structure, and a side bottom of the gas-liquid contact room, which is equipped with, to be passed through
The aperture worn passes through high-temperature gas pipe 8, and is welded to connect；Crossing cold house 3 is closed hollow square body structure, is internally provided with spiral shell
Shape natural gas line is revolved, side is equipped with through-pore and passes through natural gas inlet pipe 4 and natural gas outlet pipe 5, and is welded to connect, spiral shape
Natural gas line is separately connected with natural gas inlet pipe 4 and natural gas outlet pipe 5, the bottom through-pore for crossing cold house 3 and supercooling
One end of liquid return pipe 7 is welded, and the other end of the supercooled liquid return pipe 7 runs through with the another side bottom of gas-liquid contact room 1
Aperture welding, 7 medial fascicle of supercooled liquid return pipe (mouth) and supercooled liquid are in charge of 6 welding.
Wherein, 1 height of gas-liquid contact room was greater than the height of cold house 3, this two outdoor of gas-liquid contact room and excessively cold house
Surface fitting welding, being bonded on welding surface has the by-pass port 2 through connection close to top, and gas-liquid contact room and supercooling is indoor
Space connection, the gas-liquid contact room and the bottom welding support (not shown) for crossing cold house.
Wherein, the top wall surface that the high-temperature gas pipe 8 is located on the pipeline section of gas-liquid contact room offer multiple apertures or
