Description
Technical field
The utility model is related to feed liquid evaporation concentration technique fields, and in particular to a kind of falling film evaporator.
Background technology
Forced-circulation evaporation is by external force --- circulating pump makes liquid be recycled, when circulating liquid flows through heater device
It is heated, then in the pressure reduction of vaporization chamber, part is evaporated, to which liquid to be cooled to the boiling point temperature under the corresponding pressure
Degree forms fouling or generation crystallization for avoiding the product to boil on heating surface.
The heating device that existing falling film evaporator evaporation process uses is generally using the double-deck knot formed by inner and outer wall
Structure, inner wall are passed through the liquid for needing to heat, and outer wall is passed through the liquid that steam heats needs and heats, in the prior art inner wall
For the consistent barrel-like structure of diameter everywhere, since liquid flows through, speed is fast, is unfavorable for the heating of liquid at center, while cannot be right
Liquid carries out water conservancy diversion, and the efficiency of heating surface is low.
Invention content
Technical problem to be solved in the utility model is：A kind of falling film evaporator is provided, existing skill can be effectively solved
The heating device of art falling film evaporator there is technical issues that be unfavorable at center liquid heating and cannot be to.
The purpose of this utility model is realized by following technical measures：
Falling film evaporator, including vaporization chamber, circulating pump and heating room, the vaporization chamber bottom pass through circulation pipe and heating room
Bottom is connected to, and the circulating pump is located on the circulation pipe, and the heating room upper end passes through diversion pipe and the vaporization chamber upper end
Connection, the heating room include inner wall and outer wall, are hollow structure, the diversion pipe and institute among the inner wall and the outer wall
Circulation pipe to be stated all to be connected to the inner wall, the outer wall upper end is equipped with steam inlet, and the outer wall lower end is equipped with condensation-water drain,
The inner wall is equipped with spiral groove.
Preferably, the screw pitch of the groove is 0.5-1.5 times of inner diameter, and the groove outermost width is that inner wall is straight
0.2-0.5 times of diameter, the depth of the groove are 0.1-0.5 times of inner diameter.
Preferably, the inner wall is the compound inner wall of titanium.
Preferably, the outer wall is equipped with muff.
After using said program, the utility model has the beneficial effects that：
The inner wall that the utility model falling film evaporator heats room is equipped with spiral groove, is conducive to the indoor centre bit of heating
The liquid set is heated, while helical structure has guide functions to liquid, is conducive to liquid in heating indoor moveable.
Inner wall is the compound inner wall of titanium, improves bonding strength and corrosion resistance, is not susceptible to asking for liquid leakage in tank body
Topic.
Outer wall is equipped with muff, so that internal heat is utilized, reaches energy saving purpose.
In conclusion the utility model falling film evaporator heating effect is good, heat utilization ratio is high, and has water conservancy diversion to liquid
Effect improves the efficiency of liquid evaporation concentration.
