Material mouth and feed inlet；It is connected between circulating pump and heat exchanger by connecting tube；Spray tube be arranged in separator, spray tube with point
Upper circular tube connection outside from device, separator offer the via hole that cooperation spray tube passes through.
The feed liquid of room temperature is flowed into from feed inlet, is sent into heat exchanger and is heated through circulation pumping action, after upper circular tube
Spray tube is flowed into, the evaporator that the feed liquid of high temperature enters under vacuum after being sprayed by spray tube is flashed, the temperature after flash distillation
If reduced concentrate enters lower circulation pipe concentration and reaches requirement, it is discharged by discharge port, it, can be into if concentration not up to requires
Enter after circulating pump heats again to heat exchanger and flashed into separator, design in this way improves evaporation efficiency and vapor-liquid separation effect
Fruit；
Specifically, evaporator air pressure inside is reduced due to being vacuum inside evaporator, so that feed liquid boiling point reduces,
Further improve evaporation efficiency.
Preferred technical solution is that separator is equipped with mist eliminator, and mist eliminator is arranged in the inside of separator and is located at spray
Between pipe and venthole.
Mist eliminator is provided in separator can reduce the vapor liquid foam entrainment rate after separator flashes.
Preferred technical solution is that multiple spray heads are evenly equipped on spray tube, and spray head is connected to spray tube.
Multiple spray heads can increase spray area, improve flash efficiency.
Preferred technical solution is that spray head successively includes changeover portion, compression section and nozzle, compression along feed solution flow direction
Section internal diameter is less than changeover portion and nozzle, and nozzle is back taper pipe.
Feed liquid under the action of circulating pump at a high speed into spray head inlet after enter changeover portion, pass through compression section, material
When liquid enters compression section because channel becomes smaller suddenly, and flow velocity is multiplied, and such feed liquid mist formation drop-wise after reaching nozzle sprays,
The specific surface area of feed liquid greatly increases at this time, and evaporation efficiency also greatly increases therewith, and the feed liquid of mist formation drop-wise is because of surface tension
Change, prevent foam, from being formed, smaller drop makes vapor-liquid separation more abundant.
Preferred technical solution is that spray head is vertically arranged, and spray head includes 1 to 3 upper spray head and multiple lower sprays
The middle part of spray tube is arranged in head, upper spray head, and lower spray head is evenly arranged on spray tube.
Lower spray head is evenly arranged on spray tube, and nozzle downward, enables to the feed liquid of droplet shape uniformly to dodge in separation chamber
It steams, improves evaporation efficiency；The setting of upper spray head in the middle part of spray tube and Peng Zui upward, increase spray area, while from upper
The bottom of mist eliminator is penetrated in the mist droplet material liquid punching that the nozzle of spray head sprays, prevent the foam adsorbed on mist eliminator is from shaping,
Again reduce vapor liquid foam entrainment rate.
Advantages and beneficial effects of the utility model lie in that
Feed liquid enters back into after heat exchanger heats carries out vapor-liquid separation in separator, improve evaporation efficiency and vapour-liquid point
From effect.
