Description

Two-tube-pass graphite shell and tube seawater heat exchanger
Technical field
The utility model relates to a kind of heat transmission equipment, is specifically related to a kind of two-tube-pass graphite shell and tube seawater heat exchanger.
Background technology
Contain a large amount of impurity in seawater, have a little itself be exactly Korrosionsmedium, some is to be converted into Korrosionsmedium in process, the etching problem of seawater heat exchanger becomes a difficult problem, is difficult to find a kind of inexpensive seawater heat exchanger.
Summary of the invention
The utility model overcomes the deficiencies in the prior art, a kind of two-tube-pass graphite shell and tube seawater heat exchanger has been proposed, described heat exchanger utilizes tube-type graphite heat exchanger further to improve and does, the tube side of tube-type graphite heat exchanger passes into Korrosionsmedium usually, uses tube-type graphite heat exchanger more common as the ammonia alkali industry.Can with fresh water, can be with seawater, also can come heat exchange with the water that contains other media, quality is light, cost is low, reasonable price.
the technical solution of the utility model is, two-tube-pass graphite shell and tube seawater heat exchanger, comprise the tube bank of sealing steel barrel shrond and impermeable graphite, the tube bank of described impermeable graphite is arranged on can inside, regularly arranged according to equilateral triangle, a side at described steel circular cylindrical shell is respectively equipped with cooling water outlet and cooling water inlet, top at described steel circular cylindrical shell is provided with hot water inlet, opposite side at described steel circular cylindrical shell is provided with evacuated tube, be respectively equipped with hot water outlet and discharging hole below described steel circular cylindrical shell, described cooling water outlet and cooling water inlet are connected with the graphite tube bank respectively, hot water inlet and hot water outlet are connected with can respectively, be provided with baffle plate in can.
Described graphite tube bank is an integrative-structure that is assembled with binding agent by impermeable graphite heating tube and impermeable graphite tube sheet.
The beneficial effects of the utility model:
1) the utility model is many tube side, therefore the heat exchanger tube quantity of every journey is a half than single tube journey, namely circulation area is a half, so under same flow, theoretical velocity in pipe has also just been Duoed one times than the single tube journey, when the tube fluid heat transfer coefficient had considerable influence to overall heat-transfer coefficient, two-tube-pass improved 2 times than the flow velocity of single tube journey, therefore the corresponding raising of heat transfer coefficient.
2) the utility model Corrosion Protection is good, can use various heat transferring mediums, cost low, and wear-resisting, not fragile, utilize the graphite heat exchanger of the good characteristic manufacturing of graphite material, the instead of titanium plate type heat exchanger not only reduces on cost greatly, and its technical characteristic, manufacturing and maintenance are more even better than plate type heat exchanger.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing is structural representation of the present utility model.
In figure, 1, cooling water outlet; 2, hot water inlet; 3, impermeable graphite tube bank; 4, evacuated tube; 5, hot water outlet; 6, discharging hole; 7, cooling water inlet.
The specific embodiment
Shown in accompanying drawing, the utility model comprises sealing steel barrel shrond and impermeable graphite tube bank 3, and it is inner that described impermeable graphite tube bank 3 is arranged on sealing steel barrel shrond, regularly arranged according to equilateral triangle.A side at described steel circular cylindrical shell is respectively equipped with cooling water outlet 1 and cooling water inlet 7, be provided with hot water inlet 2 on the top of described steel circular cylindrical shell, opposite side at described steel circular cylindrical shell is provided with evacuated tube 4, be respectively equipped with hot water outlet 5 and discharging hole 6 below described steel circular cylindrical shell, described cooling water outlet 1 and cooling water inlet 7 are connected with the graphite tube bank respectively, and hot water inlet 2 and hot water outlet 5 are connected with can respectively.Described graphite tube bank is an integrative-structure that is assembled with binding agent by impermeable graphite heating tube and impermeable graphite tube sheet.Some baffle plates are installed in can.Baffle plate can improve hydrothermal fluid speed, force fluid in accordance with regulations distance repeatedly cross-current through the graphite tube bank outside, enhance fluid turbulent extent.The fluid that temperature is higher is restrained wall by graphite and is transferred heat to the lower fluid of temperature, and the fluid that temperature is higher is cooled, and the fluid that temperature is lower is heated and then realizes two fluid heat transfers.When being used in the seawater to make heat exchange in sea-farming, corrosion resistance is better.And due to the two-tube-pass heat exchanger many a tube side, therefore the heat exchanger tube quantity of every journey is a half than single tube journey, namely circulation area is a half, so under same flow, theoretical velocity in pipe has also just been Duoed one times than the single tube journey, when the tube fluid heat transfer coefficient had considerable influence to overall heat-transfer coefficient, two-tube-pass improved 2 times than the flow velocity of single tube journey, therefore the corresponding raising of heat transfer coefficient.Compare with its background technology: the heat transfer coefficient of this equipment is higher, and in the unit interval, the medium of the heat exchange of wanting increases.
