The specific embodiment:
Below in conjunction with accompanying drawing the utility model is done nearly step explanation:
As shown in Figure 1, a kind of mixed heat exchanger that abates the noise and vibrate, comprise housing 5, housing 5 is provided with cryogenic media inlet 1, cryogenic media outlet 7 and high-temperature medium inlet 4, cryogenic media inlet 1, cryogenic media outlet 7 are arranged on the long axis direction of housing 5 and with high-temperature medium inlet 4 and form three-port structures, be provided with silencing means 9 in housing 5, silencing means 9 is fixed in the housing 5 by bearing rib 8, and silencing means 9 maintains the gap with housing 5; Be fixed with the high-temperature medium jet pipe 13 with a lot of apertures in silencing means 9, high-temperature medium jet pipe 13 is communicated with high-temperature medium inlet 4 by the high-temperature medium air deflector 10 of arc, high-temperature medium air deflector 10 collection water conservancy diversion, eddy flow, injection, and speedup is.Be drilled with a lot of apertures on the wall of silencing means 9, high-temperature medium inlet 4 is provided with web plate 3, be provided with discharging hole 12 in the bottom of housing 5, be provided with cryogenic media nozzle 11 at cryogenic media 1 place that enters the mouth, the outer periphery of cryogenic media nozzle 11 is equipped with hub reinforcement pipe 2.Between housing 5 and cryogenic media outlet 7, be provided with and take over 6.
Injection enters air deflector one-level mixing chamber 14 steam several apertures from stainless web plate 3 in using this device process, mixes rapidly with the water that enters this chamber, finishes elementary Hybrid Heating process; Meanwhile, the heat of steam also heats for the liquid in the housing 5 in the mode of conducting heat by the tube wall that enters high-temperature medium air deflector 10.Make the temperature reduction of the high-temperature medium that is flowed out by high-temperature medium air deflector 10, the cryogenic media temperature that enters in the cylindrical shell raises, thereby reduces the carbonated drink temperature difference that secondary mixes, and helps steadily carrying out of secondary mixing.
