Abstract

The invention discloses a forced-circulation fixed tube sheet type evaporator, which comprises a barrel and at least one expansion joint, wherein the at least one expansion joint is arranged on the barrel; a plurality of cross baffles which are distributed in a staggering manner are arranged inside the barrel at intervals up and down; the cross baffles are correspondingly provided with a plurality of through holes; pipe spacers and pull rods are arranged in the through holes in an insertion manner; a plurality of separating plates are arranged in a cavity, near a bottom end, of the barrel; the bottom end of the barrel is provided with a plurality of emptying openings; one side, near a top end, of the barrel, is provided with a medium inlet; the other side, near the top end, of the barrel is provided with a medium outlet; a liquor condensate inlet and a liquor condensate outlet are arranged above the medium inlet and the medium outlet. The-forced circulation fixed tube sheet type evaporator is simple and compact in structure, can bear higher pressure and is low in manufacturing cost; a tube pass is cleaned conveniently; a tube is easily blocked or replaced when being damaged. The heat transfer efficiency is high; the evaporation capacity is large.

Description

Forced circulation fixed tube sheet type evaporimeter
Technical field
The present invention relates to the transformation of heat exchange equipment, be mainly used in evaporation crystallization equipment.
Background technology
Heat exchanger is many wide variety of common processing equipment of industrial department.Generally, in the construction in chemical plant, heat exchange Device accounts for the 11% ~ 40% of gross investment.Its advance, reasonability and operating reliability will directly affect quality, the quantity of product And cost.The easy plugging of heat exchanger of prior art, easy fouling, have much room for improvement.
Content of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of simple in construction, effectively improve heat conduction efficiency, effectively anti- Only plugging, fouling, prevents the forced circulation fixed tube sheet type evaporimeter of temperature distortion.
For realizing the object of the invention, provide techniques below scheme:Forced circulation fixed tube sheet type evaporimeter, its feature exists In including cylinder, at least one expansion joint of being arranged on cylinder, inner barrel be arranged at intervals with up and down some pieces staggered Deflection plate, on deflection plate, correspondence offers several through holes, is inserted with distance sink tube, pull bar in through hole, cylinder nearly bottom chamber Inside being provided with some pieces of demarcation strips, cylinder bottom offers several discharging holes, and side, cylinder nearly top offers medium entrance, Opposite side offers media outlet, and medium import and export is provided above condensate liquid import and export.
As preferably, the nearly top of cylinder is provided with fixed gas mouth, and the nearly bottom of cylinder is provided with corresponding with fixed gas mouth Lower fixed gas mouth.
As preferably, expansion joint begins with indirect steam import.
The scene temperature table mouth of pipe as preferably, below expansion joint.
As preferably, the nearly bottom of cylinder is separately provided with visor.
Beneficial effect of the present invention:Present configuration is simple, compact, can bear elevated pressures, and cost is low, tube side cleaning side Just, it is easy to plugging or replacing during damaged tubular.Heat transfer efficiency is high, and evaporation capacity is big.
Brief description
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Embodiment 1:Forced circulation fixed tube sheet type evaporimeter, including cylinder the 1st, be arranged on cylinder 1 at least one is swollen Swollen joint the 2nd, cylinder 1 is internal is arranged at intervals with some pieces of staggered deflection plates 3 up and down, and on deflection plate 3, correspondence offers some Individual through hole, is inserted with distance sink tube the 4th, pull bar 5, is provided with some pieces of demarcation strips 6, cylinder 1 end in the chamber of cylinder 1 nearly bottom in through hole End offers several discharging holes 7, and the nearly side, top of cylinder 1 offers medium entrance 8, and opposite side offers media outlet 9, is situated between Matter import and export(8、9)It is provided above condensate liquid import and export(10、11).The nearly top of cylinder 1 is provided with fixed gas mouth 12, cylinder The nearly bottom of body 1 is provided with lower fixed gas mouth 13 corresponding with fixed gas mouth 12.Indirect steam import 14 is begun with on expansion joint 2. The scene temperature table mouth of pipe 15 below expansion joint 2.The nearly bottom of cylinder 1 is separately provided with visor 16.Demarcation strip:Increase number of tube passes, carry Senior executive's inner fluid speed.Flow velocity increases, and heat transfer efficiency improves;Deflection plate:Improve shell-side fluid(Such as steam)Flow velocity and turbulence Degree;Expansion joint:The temperature difference between housing and pipe is bigger(60~70℃), and housing bear pressure not high when, benefit can be used Strong circle(Also known as expansion joint).Owing to two pieces of tube sheets are all fixed with housing, when housing, heat exchanger tube is heated, pressurized all can deform, Add expansion joint to reduce thermal stress and carry out absorbing thermal expansion difference.
