Description
Technical field
The utility model relates to a kind of shell-and-tube cooler.
Background technology
Alcohols is a raw material commonly used in the commercial production, in commercial production, usually can produce the how pure lean solution of a large amount of ethene, promptly distills raffinate remaining in the ethylene glycol production process; It contains ethylene glycol, diethylene glycol and other alcohols material, and its alcohols content is lower, impurity is more, and through using distillation still; Then through condenser condenses; Can reclaim the alcohols cut in the useless alcoholic solution, be used for as the raw material of producing the modulation cooling fluid, not only environmental protection but also energy savings.How pure the structure of condenser of using in the existing ethene lean solution purifying technique be complicated; And the heat exchange effect of the condensing and recycling of ethylene glycol is unsatisfactory after being used to gasify; And the cylindrical shell thickness of condenser is generally 10 millimeters, in order to reduce stress, need establish plural expansion joint; This has increased the complexity that condenser is made to a certain extent, has increased production cost.
Summary of the invention
The problem that the utility model will solve provides a kind of simple in structure, and good effect of heat exchange, the shell-and-tube cooler that production cost is low especially are suitable for use in the purifying technique of the how pure lean solution of ethene and apply.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of shell-and-tube cooler comprises a cylindrical shell, two tube sheets and two end sockets; Said tube sheet is connected with cylindrical shell through ring flange; Said end socket is welded on the tube sheet, and the upper end of one of them end socket is provided with charging aperture, and the lower end of another end socket is provided with discharging opening; The left upper end of said cylindrical shell is provided with delivery port, and the bottom righthand side of cylindrical shell is provided with water inlet; Be provided with the heat exchanger tube of some single-pass in the said cylindrical shell, heat exchanger tube is fixed on the tube sheet, and is communicated with end socket; Between delivery port and water inlet; Be staggeredly equipped with the deflection plate of some equidistance in the cylindrical shell; Said deflection plate is fixed on the positioning pipe that is installed with pull bar; One of pull bar is fixed on a nearest tube sheet of charging aperture, and the other end of pull bar is fixed on last nearest piece deflection plate of water inlet; The thickness of said cylindrical shell is 6 millimeters, and the middle part of cylindrical shell is provided with an expansion joint, and the lower end of said cylindrical shell is provided with saddle.
Preferably, the diameter of said charging aperture is greater than the diameter of delivery port and water inlet, and the diameter of said discharging opening is less than the diameter of delivery port and water inlet.
Preferably, be equipped with discharging hole, be beneficial to the cleaning and the maintenance of condenser in the lower end of the end socket that is provided with discharging opening and the lower end of said expansion joint.
Advantage and the good effect that the utlity model has are:
1, owing to adopt technique scheme, the thickness of cylindrical shell is reduced to 6 millimeters from 10 millimeters, and an expansion joint only need be set, and can reach the effect that reduces stress, has reduced the manufacture difficulty and the production cost of condenser, has prolonged the service life of condenser;
2, reduced the shell side flow velocity through the staggered deflection plate of the polylith that in cylindrical shell, is provided with, conduct heat with the fluid resistance performance be improved significantly, make the heat exchange effect be improved significantly;
3, through diameter setting to charging aperture, discharging opening, better met the production demand of ethylene glycol condensation, the utlity model has advantages such as processing cost is low, simple in structure, easy to maintenance, good effect of heat exchange.
