A spiral coiled pipe type jet fluid exchanger comprises a straight cylinder-shaped outer housing, wherein a jet flow nozzle is mounted inside the outer housing, and the jet flow nozzle and the outer housing are coaxially arranged; the front end of the jet flow nozzle is fixed on the inner wall of the outer housing; the middle part of the jet flow nozzle is a narrow diameter section; a double helix groove is formed in the inner wall of the narrow diameter section; low pressure fluid inlets are formed in positions, downstream the fixed position of the jet flow nozzle, on the outer housing; the low pressure fluid inlets are communicated with the outlet of the jet flow nozzle; at least three groups of coiled pipes are arranged downstream the outlet of the jet flow nozzle. According to the designed concave coiled pipe type jet fluid exchanger, a low pressure fluid pipeline is eliminated; heat exchanging during the mixing of high pressure fluids and low pressure fluids is promoted by the three groups of coiled pipes, so that the high pressure fluids and the low pressure fluids are fully mixed to improve the heat exchange efficiency; the structure is simple integrally, and the occupied space is small.
Description
technical field [0001] The invention relates to a spiral coil type jet fluid exchanger, which belongs to the field of jet heat exchangers. Background technique [0002] The ejector heat exchanger is an ejector for the purpose of heat exchange. It is a device for mixing two fluids with different pressures and temperatures and exchanging energy during the mixing process. According to the different fluids to be mixed, it can be divided into steam-water exchangers, water-water exchangers, steam-steam exchangers, etc. Among them, the steam-water exchanger has a huge structure, low heat exchange efficiency, and uneven jet mixing, resulting in low overall work efficiency. Contents of the invention [0003] The object of the present invention is to provide a spiral-coil type jet fluid exchanger, which ensures efficient operation of the heat exchanger and saves space. [0004] The purpose of the present invention is specifically achieved through the following technical solutions:...
