Abstract
The utility model discloses an external auto-rotation spring type heat exchange tube, comprising a heat exchange tube body; an auto-rotation spring which can axially move along the heat exchange tube body is sheathed outside the heat exchange tube body under the action of fluid outside the tube. The external auto-rotation spring type heat exchange tube has the advantages that the heat exchange performance of the outer wall of the heat exchange tube is enhanced, the outer wall of the heat exchange tube can be effectively prevented from being scaled, partial scaling at the outer wall of the heat exchange tube can be removed in an on-line manner, the heat exchange effect is enhanced and the comprehensive performance is good.
Description
Technical field
The utility model relates to heat exchanger tube, relates in particular to external spin spring heat exchanger tube.
Background technology
Heat exchanger is widely used in the industries such as oil, chemical industry, metallurgy, the energy, light industry, pharmacy, electric power as a kind of important process device.The quality of heat exchange property directly affects the height of the heat-economy of process industrial.In view of heat exchanger important function and energy consumption present situation thereof aborning, the heat transfer efficiency and the performance thereof of improvement and raising heat exchanger have become the important channel of reducing investment outlay, saving energy consumption, improve production capacity.The present enhancements of exchange heat pipe can be divided into and strengthen in the exchange heat pipe and exchange heat pipe two kinds of augmentation of heat transfers outward.Enhancements in the heat exchanger tube mainly contains and add spiral winding, hurricane band, flight, tie, static mixer and blender etc. radially in heat exchanger tube; The outer reinforcement research of exchange heat pipe comprises the research of supporter between the research of cast and pipe, can be divided into board-like support according to different tube bundle support structures, rod-type supports, several forms such as cavity ring support and pipe self-supporting, the change of heat exchange pipe external surface shape mainly is to process groove and fin at its outer surface, the fluted heat exchanger tube of outer surface comprises helix tube, band pipe and bellows etc.Have following shortcoming in the outer enhancements of now common heat exchanger tube: (1) is difficult to keep higher heat exchange efficiency of long period; (2) do not have the function of on-line cleaning dirt; (3) part tube manufacture expense costliness.Can keep higher heat exchange efficiency, again can online scale removal and the good comprehensive properties heat exchanger of effectively pre-good antiscale property seldom.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of can thermoexcell the outer wall heat exchange property, effectively prevent the fouling of heat exchanger tube outer wall, can onlinely remove the fouling of heat exchanger tube outer wall section, strengthen the external spin spring heat exchanger tube of heat exchange effect, good combination property.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of external spin spring heat exchanger tube comprises heat exchange pipe body, and described heat exchange pipe body is arranged with outward can be at the axially movable spin spring of extratubal fluid effect lower edge heat exchange pipe body.
The external diameter of described heat exchange pipe body is D, and the internal diameter of described spin spring is d, 1.05D≤d≤1.15D.
The length of described heat exchange pipe body is L, and the length of described spin spring is s, 0.75L≤s≤0.9L.
Compared with prior art, advantage of the present utility model is:
External spin spring heat exchanger tube of the present utility model, being outside equipped with in heat exchange pipe body can be at the axially movable spin spring of extratubal fluid effect lower edge heat exchange pipe body, when fluid flows along the spin spring, the hand of spiral at the spin spring produces shunting, heat exchanging tube body outer wall forms and washes away, the attenuate boundary layer thickness, and fluid can form turbulent flow, strengthened the heat exchange effect; Fluid heat exchanging tube body outer wall wash away the scale velocity that has effectively reduced the heat exchange pipe body outer wall, increased heat transfer coefficient, strengthened heat transfer property, prolonged the service life of heat exchanger tube; The mobile meeting of fluid produces axial force to the spin spring, the spin spring is produced to be moved axially, when moving axially when being obstructed of spring of spin can produce reaction force by compression, and produce reverse moving axially, the spin spring can be implemented on the heat exchange pipe body and move reciprocatingly effectively prevention pipe outer wall fouling under the effect of fluid force and self reaction force like this, and the fouling that can effectively remove the heat exchange pipe body outer wall, play the effect of enhanced heat exchange performance.The spin spring inside diameter is bigger than heat exchange pipe body external diameter, and spin spring length is shorter than heat exchange pipe body length, and the spring of guaranteeing to spin can move at the heat exchanger tube external freedom.External spin spring heat exchanger tube of the present utility model can be realized self cleaning in the heat exchanger operation, has good enhanced heat exchange performance simultaneously, and applied range simple in structure, has very high economic serviceability and promotional value.
