Upper and lower two parts, the evaporation tube bottom passes through filter, and is tightly connected with the junction of filter；The evaporation
Pipe is internally provided with heat exchanger tube, and the heat exchanger tube upper and lower ends are respectively arranged with gear tube sheet and lower block tube sheet, the lower block pipe
Plate is located at filter lower end.
Preferably, spoiler is installed inside the heat exchanger tube additional, when the spoiler in heat exchanger tube be spiral shape, its pitch is to change
3-4 times of heat pipe internal diameter, fin width are 0.08-0.2 times of heat exchange bore.During actual fabrication, spoiler total length is not
Preferably exceed heat exchanger tube pipe range, recommend the half that its length is heat exchanger tube pipe range.Spoiler in heat exchanger tube is by steel material or modeling
Property material make, its thickness needs the requirement of sufficient strength and stiffness.Recommend thickness 1mm, but not limited to this.Spoiler in heat exchanger tube leads to
Air-flow caused by pervaporation and Flow of Goods and Materials can drive.Without evaporator external energy.When flow velocity is slow, itself spoiler
Change material flow pattern in heat exchanger tube.Based on turbulent flow.When flow velocity is accelerated, also faster, heat exchange intraductal turbulance is imitated for spoiler rotation
Fruit will be apparent from.
Preferably, honeycomb structure is opened up on the filter, it is desirable to which its is every square centimeter, there is the honeycomb hole of more than 5.Or
Person's filter is made by silk screen.According to the granularity size of material come its mesh number of requirement.
Preferably, the heat exchange bottom of the tube is provided with orifice plate, and the orifice plate is arranged between heat exchanger tube and lower block tube sheet.
Preferably, aerator is installed on the filter additional, aerator can be located at filter top, bottom or both sides
Have.
Aerator uses tube aerator, is connected by flange and outside.
The beneficial effects of the invention are as follows：
1st, can be transformed using original evaporator or newly-built.2nd, heat exchange pipe of evaporator heat exchange efficiency is at longer one section
Interior stabilization declines unobvious.3rd, tube fluid is exchanged heat based on turbulent flow, increases heat exchanger efficiency.4th, add in process units
The utilization of low-grade steam.5th, it is also effective when the evaporator feed separation temperature difference is smaller.6th, after using two effects or multiple-effect series connection,
Increase the utilization rate of steam.7th, the evaporator cycle of operation extends.8th, cost of labor is reduced, evaporation efficiency is high, evaporation time
Accelerate.
