Theoretically, the steam of evaporation can be by the vavuum pump suction evacuation.But absolute pressure is less, the steam gasification volume is just larger, in vacuum precooling machine, the water vapor volume is about 210,000 times of water liquid volume, all only aspirate by vavuum pump such as all steam, be to be difficult to make fore-cooling room's pressure to maintain lower level, cooldown rate is also just quite slow, can't reach predetermined target; For the small size vacuum pre-cooler, select large-scale vacuum, though can make fore-cooling room's pressure maintain reduced levels, the vavuum pump power that select this moment is larger, system's power consumption can increase 2-3 doubly.So the steam that produces in the vacuum precooling machine all (is the evaporimeter of enclosed refrigeration system in fact by " water vessel " in the enclosed refrigeration system, but in vacuum precooling device, be commonly called water vapour coagulator or water vessel) be cooled to water droplet, hold water vessel surface and below storage tank in, put by water valve after precooling finishes and get rid of.Water vessel is not directly to play a part cooling food in the vacuum precooling device, water vessel is in the condensate water steam, the condensation chamber steam partial pressure is reduced, steam enters condensation chamber and is condensed continuously under the effect that condensation chamber pressure reduction and vavuum pump are bled, avoid steam to enter vavuum pump, in the vavuum pump compression chamber, be compressed into the globule, make pumping fluid emulsified, vavuum pump is caused damage.
In the process of vacuum cooled, water vessel catch the effect that outlet capacity directly affects vacuum cooled.If the ducting capacity of water vessel is good, steam and tube outer surface collision probability are high, water vessel to catch outlet capacity just high, the like this normal operation of guarantee vavuum pump.The surface temperature of water vessel has a direct impact for the effect of solidifying water, if temperature is too high, does not reach the too high again evaporation under the condition of low-pressure more of the purpose of solidifying water or adiabatic condensation temperature, thereby increases the load of water vessel; If temperature is excessively low, easily make heating surface form frost layer and glaciation, produce very large thermal resistance, affect equally heat-transfer effect, caused energy loss.
The water vessel of prior art can be divided into the finned coil formula and circle is filled with two kinds of transverse tube types, less to 16 millimeters transverse tubes of Φ owing to 9.5 millimeters of its Φ for finned coil formula water vessel, the spacing that the transverse tube center is 25 millimeters to 35 millimeters is relatively large, runner is many, arrange close (spacing is that 6 millimeters to 10 millimeters aluminium fin is divided into narrow and small runner take hundred with water vessel) and runner as through-type straight up without baffling, so finned water vessel condensate water steam ability (air-flow center steam can not skim over fin or the transverse tube surface directly enters vavuum pump behind the arrival water vessel top), it catches water efficient is 92% to 95%.And use (generally processing 5 to 8 cycles) after a period of time to cause ice stifled and can't normally use owing to fin and transverse tube form reason that moisture film liquid bridge freezes, the user needs often to judge whether to ice to block up according to operating position to select manually defrosting, causes very large inconvenience and affects service efficiency.
Transverse tube deflector type water vessel generally is usually used in ethylene glycol refrigerating system, its structure is that horizontal 32 millimeters seamless steel pipes of Φ are arranged in the cylinder of volume circle equably, the transverse tube central dividing plate is separated with transverse tube, form S type runner, but after preventing forming the water bridge between transverse tube, cause ice stifled, the spacing design is larger between transverse tube, spacing is 80 millimeters to 100 millimeters between general pipe, although this kind mode has been removed the stifled phenomenon of ice, the probability that has but reduced the collision of steam and transverse tube or skimmed over from the transverse tube surface owing to the larger reason of spacing, and the spacing between transverse tube and the outer drum has also caused a part of steam not skim over transverse tube and through vavuum pump air entry, the transverse tube spacing is larger in addition, air-flow is that disturbance is less by the water vessel transverse tube, so that comparatively stable by the air flow direction of water vessel, thereby greatly reduce the efficient that cold water vessel steam condenses.
