Abstract

The invention relates to a novel seawater heat exchanger. The novel seawater heat exchanger comprises a sealed cylindrical steel shell and impermeable graphite tube bundles; the impermeable graphite tube bundles are arranged inside the sealed shell and regularly arranged in a regular triangle shape; a cold water outlet and a cold water inlet are formed in one side of the cylindrical steel shell; a hot water inlet is formed in the upper portion of the cylindrical steel shell; an emptying pipe is arranged on the other side of the cylindrical steel shell; a hot water outlet and an emptying opening are formed in the lower portion of the cylindrical steel shell; the cold water outlet and the cold water inlet are communicated with the graphite tube bundles; the hot water inlet and the hot water outlet are communicated with the sealed shell; baffles are arranged inside the sealed shell.

Description

Novel seawater heat exchanger
Technical field
The present invention relates to a kind of heat transmission equipment, be specifically related to a kind of novel seawater heat exchanger.
Background technology
Containing a large amount of impurity in seawater, a little inherently Korrosionsmediums had, some is then be converted into Korrosionsmedium in process, and 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 present invention overcomes the deficiencies in the prior art, propose a kind of novel seawater heat exchanger, described heat exchanger utilizes tube-type graphite heat exchanger improve further and do, and the tube side of tube-type graphite heat exchanger passes into Korrosionsmedium usually, uses tube-type graphite heat exchanger more common as ammonia alkali industry.Can with fresh water, can with seawater, also heat exchange can be carried out with containing the water of other media, quality is light, cost is low, reasonable price.
Technical scheme of the present invention is, novel seawater heat exchanger, comprise sealing steel cylinder shell and impermeable graphite tube bank, described impermeable graphite tube bank is arranged on can inside, regularly arranged according to equilateral triangle, cooling water outlet and cooling water inlet is respectively equipped with in the side of described steel cylinder housing, hot water inlet is provided with on the top of described steel cylinder housing, evacuated tube is provided with at the opposite side of described steel cylinder housing, hot water outlet and discharging hole is respectively equipped with in the below of described steel cylinder housing, described cooling water outlet and cooling water inlet are restrained with graphite respectively and are connected, hot water inlet is connected with can respectively with hot water outlet, baffle plate is provided with in can.
Described graphite tube bank is an integrative-structure assembled by impermeable graphite heating tube and impermeable graphite tube sheet binding agent.
Beneficial effect of the present invention:
1) the present invention is a many tube side, therefore the heat exchanger tube number ratio single tube journey of every journey is a half, namely circulation area is a half, so under same flow, theoretical velocity in pipe is also just many than single tube journey one times, when tube fluid heat transfer coefficient has considerable influence to overall heat-transfer coefficient, two-tube-pass improves 2 times than the flow velocity of single tube journey, therefore the corresponding raising of heat transfer coefficient.
2) Corrosion Protection of the present invention is good, various heat transferring medium, cost can be used low, and it is wear-resisting, not fragile, utilize the graphite heat exchanger that the good characteristic of graphite material manufactures, substitute titanium plate type heat exchanger, not only greatly reduce on cost, its technical characteristic, manufacture and maintenance are more even better than plate type heat exchanger.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Accompanying drawing is structural representation of the present invention.
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.
Detailed description of the invention
Shown in accompanying drawing, the present invention includes sealing steel cylinder shell and impermeable graphite tube bank 3, described impermeable graphite tube bank 3 is arranged on sealing steel cylinder enclosure, regularly arranged according to equilateral triangle.Cooling water outlet 1 and cooling water inlet 7 is respectively equipped with in the side of described steel cylinder housing, hot water inlet 2 is provided with on the top of described steel cylinder housing, evacuated tube 4 is provided with at the opposite side of described steel cylinder housing, hot water outlet 5 and discharging hole 6 is respectively equipped with in the below of described steel cylinder housing, described cooling water outlet 1 and cooling water inlet 7 are restrained with graphite respectively and are connected, and hot water inlet 2 is connected with can respectively with hot water outlet 5.Described graphite tube bank is an integrative-structure assembled by impermeable graphite heating tube and impermeable graphite tube sheet binding agent.Some baffle plates are installed in can.Baffle plate can improve hydrothermal fluid speed, forces fluid repeatedly laterally to flow through graphite tube bank outside by regulation distance, enhance fluid turbulent extent.The fluid that temperature is higher transfers heat to the lower fluid of temperature by graphite tube bank wall, 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 many tube sides of two-tube-pass heat exchanger, therefore the heat exchanger tube number ratio single tube journey of every journey is a half, namely circulation area is a half, so under same flow, theoretical velocity in pipe is also just many than single tube journey one times, when tube fluid heat transfer coefficient has considerable influence to overall heat-transfer coefficient, two-tube-pass improves 2 times than the flow velocity of single tube journey, therefore the corresponding raising of heat transfer coefficient.Compared with its background technology: the heat transfer coefficient of this equipment is higher, in the unit interval want the medium of heat exchange to increase.
