Description

A kind of shell-and-tube heat exchanger
Technical field:
The utility model is related to technical field of heat exchangers, and in particular to a kind of shell-and-tube heat exchanger.
Background technology:
Gas or steam, can be transformed into liquid by heat exchanger, by the heat in pipe, in the way of quickly, pass to pipe In neighbouring air.Shell-and-tube exchanger is mainly made up of parts such as tube bank, tube sheet, deflection plate, shell and end sockets, tube bank according to Connect and be securely seated between on tube sheet by welding, expanded joint, expanded and welded tube joint, tube sheet is together with cage connection.Filled on the end socket of heat exchanger There are outlet and the entrance of fluid.When carrying out caloic exchange, a kind of fluid enters heat exchanger Bottomhole pressure, another stream by tube side Body is taken over to enter in the gap (shell side) between tube bank and housing by shell to be flowed.Carried out by the temperature difference of two kinds of fluids by tube wall Heat exchange, the surface area of tube bank is exactly heat exchange area.The structure of existing Reconstruction of End Gas Separator and common condenser structure basic one Cause, structure setting is unreasonable, in-convenience in use, existing condenser structure is relatively simple, typically there was only cylinder or casing, envelope Laminar flow phenomenon can all occur in head and heat exchanger tube, internal gas and condenser pipe, and the effect of water conservancy diversion is poor, and the effect of condensation is poor, and After gas enters heat exchanger, speed, impulsive force is increased, and causes gas to enter heat exchanger skewness, easily quick Into bottom, so as to reduce the efficiency of heat exchange.
Utility model content:
Technical problem to be solved in the utility model is to overcome existing technological deficiency there is provided one kind is easy to use, Laminar flow phenomenon is avoided, gas velocity is reduced, is uniformly dispersed, the good shell-and-tube heat exchanger of heat exchange condensation effect.
Technical problem to be solved in the utility model is realized using following technical scheme:
A kind of shell-and-tube heat exchanger, it is characterised in that:Including cylinder, upper cover, low head, tube sheet, cooling tube, dividing plate and Fix bar, the upper end sidepiece of described cylinder is provided with charging aperture, and the lower end sidepiece of cylinder is provided with discharging opening, described upper envelope Head is fixedly installed on the upper end of cylinder, and described low head is fixedly installed on the lower end of cylinder, described upper cover and low head On be respectively arranged with cooling medium gateway, described tube sheet is respectively fixedly disposed between cylinder and upper cover and low head, Described cooling tube is uniformly arranged between tube sheet, and described dividing plate is fixedly installed on two side positions of inner barrel and positioned at cylinder The dividing plate of body both sides is into being staggered, and described fix bar is fixedly installed between dividing plate and the lower end of fix bar is fixedly installed on On tube sheet.
Two sides of described cylinder and it is close to the position of tube sheet and is respectively arranged with rinse mouth.Cleaning performance is good.
Fixed ear is provided with the outside of described cylinder.
The outside of described cooling tube sets cooling fins, the screw thread for being internally provided with curl of described cooling tube Groove.The cooling medium in cooling tube is avoided to occur the phenomenon of laminar flow.
The inside portion of the upper end of described cylinder and it is fixedly installed dispersion plate against the position of charging aperture.
Described dispersion plate is into cross type.So that speed is fast, the impulsive force gas having just enter into greatly point, which is let go, to be come.
The inner side of described cylinder is located at the dividing plate of top side and charging aperture is located at homonymy, and the membrane backside of top side is set The flanging being upturned, the bottom of described flanging is provided with hole slot.Gas flow rates are reduced, prevent gas from rapidly entering down Layer, and the condensed liquid in top can also be flowed into lower section from hole slot.
The beneficial effects of the utility model are:
1st, energy-efficient, the heat transfer coefficient of heat exchanger is 6000-8000W/m2.0C.All steel makes, service life It is long, up to more than 20 years.Change laminar flow for turbulent flow, improve heat exchange efficiency, reduce thermal resistance.
2nd, heat transfer rate is fast, and high temperature resistant is high pressure resistant.Compact conformation, floor space is small, lightweight, easy for installation, saves soil Build investment.Flexible design, it is complete in specifications, it is practical with strong points, save fund.
3rd, application conditions extensively, are applicable larger pressure, temperature range and medium heat exchange.Maintenance cost is low, easily Operation, the snaking cycle is long, easy to clean.Application field is wide, can be widely used for thermoelectricity, factories and miness, petrochemical industry, city concentration and supplies The field such as heat, food medicine, energy electronic, mechanical light industry.
