Description
Technical field
The utility model relates to the supporting unit chlorine liquefier of sodium metal process units, refers to a kind of vertical chlorine liquefier particularly.
Background technology
Sodium metal is one of important chemical material, and its joint product chlorine is extremely extensive in industrial purposes, as is used to produce polyvinyl chloride, chlorinated solvents, hydrochloric acid etc.Yet the volume of the chlorine Unit Weight of this gaseous state is very big, and contains other on-condensible gas and dust, the needs that can not satisfy transportation and use.Must be liquid condition with the joint product chlorine conversion of producing sodium metal for this reason.Liquid chlorine not only has chloride purity height, can satisfy some particular requirement of user and is convenient to advantages such as transportation and storage, and produces the production serialization that liquid chlorine can guarantee sodium metal manufacturer self.At present, the device that above-mentioned gaseous chlorine cyclostrophic is turned to liquid chlorine has only horizontal chlorine liquefier, its operation principle be chlorine in the heat exchanger tube of level through the liquefaction that is cooled of two flow processs, cold-producing medium R22 evaporates in that pipe is outer.Because the joint product chlorine in the sodium metal engineering contains a large amount of dust, horizontal chlorine liquefier does not have dedusting function, enter like this when finishing the liquefaction of two flow processs in the dust-laden chlorine heat exchanger tube in the horizontal direction of horizontal chlorine liquefier, the dust that heat exchanger tube and liquid chlorine outlet produce when tending to by chlorine gas liquefaction is detained and stops up and the production of sodium metal can not be carried out continuously.Dust and incrustation in the horizontal chlorine liquefier has also greatly influenced heat exchange efficiency simultaneously, has increased the cost of sodium metal production run.
Summary of the invention
The purpose of this utility model will overcome above-mentioned deficiency of the prior art exactly, and a kind of good dedusting effect, the liquid chlorine degree of purity is good, rate of heat exchange is high vertical chlorine liquefier are provided.
For realizing this purpose, the vertical chlorine liquefier that the utility model is designed, have one and be vertically arranged cylindrical shell, the upper/lower terminal of this cylindrical shell has designed upper perforated plate and lower perforated plate respectively, be densely covered with some heat exchanger tubes between upper perforated plate and the lower perforated plate, upper perforated plate, lower perforated plate and heat exchanger tube are separated into chlorine space in the heat exchanger tube and the outer cryogen of heat exchanger tube with cylindrical shell.Refrigerant inlet is arranged on the middle part wall of cylindrical shell, and refrigerant outlet is arranged on the top wall of cylindrical shell.The upper/lower terminal of this cylindrical shell also is separately installed with upper tube box and the lower tube box that communicates with above-mentioned heat exchanger tube, the inside of lower tube box is provided with a porous plate, the wall that the chlorine intake elbow passes lower tube box is inserted into the bottom of porous plate, liquid chlorine exports the position that the wall top that is arranged on lower tube box is higher than the chlorine intake elbow, and the outlet of tail chlorine then is arranged on the wall of upper tube box.The utility model adopts upright heat exchange form, its operation principle is such: after cold-producing medium flow into inner barrel by the refrigerant inlet in the middle part of the cylindrical shell, keep higher evaporation liquid level chlorine in the evaporative cooling heat exchanger tube outside heat exchanger tube to make its liquefaction, the cold-producing medium after the evaporation rises to the refrigerant outlet return-air on cylindrical shell top again.High temperature dust chlorine is then by the porous plate bottom in the chlorine intake elbow importing lower tube box, with original liquid chlorine heating and gasifying in the lower tube box.The chlorine of gasification is comparatively pure, and it rises in the heat exchanger tube with the outer cold-producing medium of pipe and carries out heat exchange, and overflow along the liquid chlorine outlet that inside pipe wall falls to lower tube box the liquefaction back that is cooled, and does not coagulate the tail chlorine outlet that tail gas rises to upper tube box and discharges on a small quantity.Because of dust is heavier than liquid chlorine, and being provided with of porous plate blocked raising up of dust, utilizes it dust can be stayed the lower tube box bottom from gravity like this.
Advantage of the present utility model is: designed chlorine intake elbow is inserted in below the porous plate of liquid chlorine liquid level, the chlorine of high temperature is with the liquid chlorine vaporizing of low temperature, the chlorine of gasification can not be taken away heavier dust and other dirt, thereby removed dust, purified chlorine, prevented that effectively dust is detained clogging, guaranteed that sodium metal production can carry out continuously.The position of designed liquid chlorine outlet is higher than the chlorine intake elbow, thereby makes the liquid chlorine after the liquefaction overflow more pure.Designed refrigerant inlet is at the middle part at cylindrical shell, thereby make cold-producing medium outside heat exchanger tube, evaporate heat absorption and remain higher liquid level, most of heat exchanger tube is immersed in the refrigerant liquid, all there is the gas, liquid of generation to become during work inside and outside the heat exchanger tube, heat exchange efficiency can significantly improve, and has reduced production cost.Simultaneously, the utility model is not only the best corollary equipment that sodium metal is produced, and also is applicable to the gas liquefaction of other engineering that contains dust, heavy dirt chlorine gas source.
