Abstract
A vacuum flash evaporation crystallizer belongs to the technical field of chemical equipment. The device comprises a crystallization tank, a circulating pipe, a distribution pipe, a vacuum pipe, a feeding hole, a discharging hole and a slag discharging hole, and is characterized in that a trap and a reflector are arranged at the upper part in the crystallization tank, the vacuum pipe is arranged at the top of the crystallization tank, the lower part of the crystallization tank is a cone, the circulating pipe is arranged outside a lower cone, the inlet end and the outlet end of the circulating pipe are arranged in the crystallization tank, the outlet of the circulating pipe is arranged in the middle of the crystallization tank and connected with the cone distributor, a cleaning device with the slag discharging hole is arranged in the middle of the circulating pipe, and. The utility model has the advantages of reasonable and simple structure, easy production and manufacture, convenient use, energy conservation and good crystallization effect. The crystallizer has small volume, no wearing parts and low operation cost. The single-person operation is realized, the labor intensity is low, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of structure of vacuum crystallizer, belongs to technical field of chemical.
Background technology
In industries such as medicine, chemical industry, there are many products to make by crystallization from solution.This class operation generally need be finished by the system that crystallizer main body, outer circulation part, vacuum plant, feed pump, discharging pump etc. are formed.The crystallizer of commercial Application has a variety ofly, and the hot solution of chemical substance is under vacuum, and a part of solvent is evaporated, and the heat in the solution is taken away by steam, and solution temperature descends and separates out crystallization, and such device is called vacuum crystallizer.Existing vacuum crystallizer is mainly installed by crystallizing tank and on crystallizing tank and circulation pipe, distributing pipe, vacuum tube, charging aperture, discharging opening, slag-drip opening etc. are set are constituted, agitator or forced circulation pump all are housed, the equipment complex structure, increased the chance of gas leakage, and the energy consumption height, the product crystal fineness is inhomogeneous.
The utility model content
The purpose of this utility model is to realize like this, the vacuum flashing crystallizer, comprise crystallizing tank, circulation pipe, distributing pipe, vacuum tube, charging aperture, discharging opening, slag-drip opening, it is characterized in that the crystallizing tank internal upper part is provided with trap, reflector, vacuum tube is installed in the crystallizing tank top, the crystallizing tank bottom is a cone, circulation pipe is installed in outside the lower cone, the turnover of circulation pipe, the mouth end is arranged in the crystallizing tank, the middle part that the outlet of circulation pipe is arranged in the crystallizing tank connects conical distributor, the cleaning plant of band slag-drip opening is housed in the centre of circulation pipe, is provided with return duct between the charging aperture on crystallizing tank lower cone and the circulation pipe and is connected.
Adopt this vacuum flash evaporation crystallizer from solution, to produce crystallization, charging aperture is on circulation pipe, because the feed liquor temperature is than mixeding liquid temperature height in the crystallizing tank, therefore feed liquid can directly rapidly increase to distributor, the pressure of crystallizer under the assisted vacuum appointed condition (crystallizing tank) can remain on≤0.09MPa, the boiling point of water is at 50～55 ℃ with this understanding, overflow the material vaporization fast of distributor cone, material can be fountain shape and gushes out under vaporization and the double action of circulation thrust, simultaneously also play the enhancing vaporization effect, in repetitive process, moisture content slows down few in the solution, concentration improves, because the solution itself that enters is just saturated, ordinary material solubility under the cooling condition reduces in addition, has a large amount of crystal in the solution simultaneously and separates out, sedimentation under the effect of gravity is carried out discharge through opening the discharging opening valve behind the certain hour.
The utility model is rational in infrastructure simple, manufactures easily, and cost is low, and is easy to use, energy savings, and crystallization effect is good.In the general crystallizer agitator to be installed, prevent the sticking wall of material material in crystallization process, this vacuum flash evaporation crystallizer is equipped with EGR, utilize temperature official post material to flow at the crystallizer fountain shape, this new device is provided with linkage path at cone base and circulation pipe in addition, because above 2 factors have solved the phenomenon of sticking wall, and need not to stir.Material is delivered to crystallizer, is in high vacuum state in the crystallizer, and material can produce rapid evaporation under corresponding conditions, simultaneous temperature reduces, and material can produce Natural Circulation in circulation pipe, and temperature of charge constantly reduces in the time of circulation, concentration improves constantly, and separates out with a large amount of crystalline solid.The volume of crystallizer is less, and is simple to operation.Can realize continuous automatic production, no consumable accessory, operating cost is low, and the one man operation reduces labour intensity, and operating cost is low, enhances productivity.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 vacuum tube, 2 traps, 3 reflectors, 4 crystallizing tanks, 5 distributors, 6 circulation pipes, 7 charging apertures, 8 discharging openings, 9 return ducts, 10 cleaning plants, 11 slag-drip openings.
The specific embodiment
Claims (1)
1. vacuum flashing crystallizer, comprise crystallizing tank, circulation pipe, distributing pipe, vacuum tube, charging aperture, discharging opening, slag-drip opening, it is characterized in that the crystallizing tank internal upper part is provided with trap, reflector, vacuum tube is installed in the crystallizing tank top, the crystallizing tank bottom is a cone, circulation pipe is installed in outside the lower cone, the turnover of circulation pipe, the mouth end is arranged in the crystallizing tank, the middle part that the outlet of circulation pipe is arranged in the crystallizing tank connects conical distributor, the cleaning plant of band slag-drip opening is housed in the centre of circulation pipe, is provided with return duct between the charging aperture on crystallizing tank lower cone and the circulation pipe and is connected.
