The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
The evaporative crystallization tank of internal heat type of the present invention comprises: bottom open type baiting valve 1, bearing 2, agitator 3, reinforcement 4, visor 5, blow-down pipe 6, gas-liquid separator 7, indirect steam outlet 8, soft water entrance 9, upper cover 10, tank body 11, charging aperture 12, tube still heater 13, low head 14, condensate water outlet 15, transmission device 16.The evaporative crystallization tank of internal heat type is comprised of upper cover 10, tank body 11, low head 14, bearing 2, and tapered upper cover 10 and low head 14 lay respectively at top and the bottom of tank body 11, has formed an enclosed tank structure.The inside of tank body 11 is disposed with gas-liquid separator 7, tube still heater 13, agitator 3 from top to bottom, and the end of agitator 3 is connected with transmission device 16.
When feed liquid enters from the bottom of tank body 11, heating steam is conducted heat and condensation between pipe, transfers heat to feed liquid.Feed liquid is heated boiling vaporization, and the indirect steam of generation and feed liquid rise at a high speed in pipe, and the indirect steam that the feed liquid after evaporation and concentration is risen at a high speed drives, and along tube wall, becomes membranaceous rising to be constantly heated evaporation.Feed liquid is concentrated to top exit gradually from heating clamber bottom, and concentrate enters gas-liquid separator 7, and indirect steam is discharged from the indirect steam outlet 8 of upper cover 10.A concentrate part is passed through circulation pipe, then enters heating clamber bottom, continues to concentrate, and another part reaches the concentrate of concentration requirement can emit from the bottom of low head 14, thereby realizes the process of whole evaporative crystallization.
The concentration that adds a certain amount of solvent or diluent liquid product extremely final needs of heating evaporation under the effect of stirring.For keeping quantitative liquid, by regularly adding the mode of feed liquid can reach semicontinuous operation in evaporation process.
Evaporative crystallization tank body of the present invention adopts sanitation-grade to open soon interface outward.Several visors 5 are equipped with, the interfaces such as rotating wash bowl and nitrogen inlet.And, evaporative crystallization tank of the present invention adopts SUS304 stainless steel, and crystallizing tank inwall is processed through mirror finish, and totally enclosed design is guaranteed that material is under free of contamination state all the time and operated, equipment sealing adopts special sanitation-grade mechanical seal, guarantees that material is not contaminated.
The present invention selects hollow helix(ribbon type) agitator 3 structures can increase heat exchange area, improves heat exchange efficiency, promotes crystallization production capacity, and charging discharging is convenient; In equipment chuck, can pass into steam or refrigerant so that the advantage such as material, under optimum temperature, has efficiency high, easy to operate.
In operating process, should control charging liquid measure, the amount of moisture through once concentration evaporation, can not be greater than 80% of inlet amount, if charging is too much, pipe bottom hydrops is too much; Very little, can there is tube wall coking phenomenon in charging.Material adds after crystallizer, starts agitator, passes into cooling water, and crystallization control temperature is slowly grown up crystal, after crystal grain reaches requirement, emits magma.
Internal heat type evaporative crystallization tank of the present invention has advantages of that heat exchange area is large, circulate in tank, with short production cycle, single tank output is large etc.
