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.
