Abstract
The utility model discloses an anti-icing heat exchanging pipe, which comprises a bearing plate. The outer wall of the bearing plate is equipped with four fins, the fins are radially distributed along a radial direction of the bearing plate, and spaced angles among adjacent fins are identical. The anti-icing heat exchanging pipe reduces frosting and icing speed and increases defrosting and deicing capacity, thereby increasing using efficiency of a whole gasifier, prolonging service life of the heat exchanging pipe and then reducing investment cost.
Description
Technical field
The utility model relates to a kind of gasifier, particularly a kind of heat exchanger tube of gasifier.
Background technology
Gasifier is a kind ofly to change liquid the equipment of gas into, and gasifier is divided into air temperature type gasification, electrical heating type gasification and three kinds of forms of steam formula heating and gasifying.Wherein air-heating type gasifier have non-maintaining, exempt from thermal source, advantage such as easy to operate, therefore all obtained using widely in every field.Air-heating type gasifier is the special equipment that at normal temperatures cryogenic liquid is gasified, air-heating type gasifier is to utilize air to carry out heat exchange, can be divided in theory during its duty cold, the gasification, the heating three phases, be mainly used in cryogen, as: the gasification of media such as LO2, LN2, LAR, LNG, LC2H4, promptly cryogenic liquid is changed into gas at normal temperature, to satisfy the application in each field such as iron and steel, solar energy, electronics, shipbuilding, Gas Industry, chemical industry.Air-heating type gasifier utilizes atmospheric environment as thermal source, carries out heat exchange by star-like fin heat exchange pipe, makes various cryogenic liquids be gasificated into gas near normal temperature.Cryogenic gas converter mainly is made up of parts such as star fin heat exchange pipe, bend pipe, supporting leg, connector, flanges.
The gasifier heat exchanger tube form that generally adopts is 8 fins (seeing accompanying drawing 1) combined types in the market, promptly no matter cold excessively, gasification or bringing-up section, be the common heat exchanger tube of 8 fins, this method is that tradition also is modal a kind of way the most, but there is certain defective in it.
Gasifier is in working order the time, enter the super cooled sect of gasifier when cryogenic liquid, the cold energy that middle steam of super cooled sect heat exchange fin surrounding environment (atmosphere) and cryogen pass to atmosphere meets, steam is met cold suddenly, condense into frost at the finned tube outer surface, As time goes on, can be more and more serious, and do not have built-in distributing fin and can make in the fluid passage heat exchange insufficient, phenomenons such as the outer frosting of heat exchanger tube, ice extend to the gasification section and the bringing-up section of back rapidly).In gasification section, when gasifier was stopped using, frost, ice that its surface forms were not easy to come off at short notice, and cause the service efficiency of whole gasifier to reduce greatly, finally cause the user just can keep its ordinary production by buying more gasifier.
The utility model content
At above-mentioned the deficiencies in the prior art, the technical problems to be solved in the utility model provides a kind of gasifier heat exchanger tube of new structure, but this heat exchanger tube effectively preventing heat exchanger tube surface freezes the service life of prolongation heat exchanger tube.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of anti-freeze heat exchanger tube comprises a pressure-bearing pipe, and the outer wall of described pressure-bearing pipe is provided with 4 fins, and to radially distributing, the interval angle between adjacent two of the described fin is identical along described pressure-bearing caliber for described fin.
According to above-mentioned major technique feature, the inwall of described pressure-bearing pipe is provided with several distributing fins, described distributing fin along described pressure-bearing caliber to radially distributing.
According to above-mentioned major technique feature, described pressure-bearing pipe, fin, distributing fin are a monolithic construction.
According to above-mentioned major technique feature, the material of described anti-freeze heat exchanger tube is an aluminum alloy materials.
Technique scheme has following beneficial effect: at the super cooled sect of gasifier, change the present anti-freeze heat exchanger tube of 4 fins into by original common 8 fin heat exchange pipes, because the angle and the spacing of its outer surface fin are very big, frost or ice are difficult to attached to fin surface, be that the finned tube surface has possessed rapid defrost, the function of the frost that falls, particularly when gasifier was stopped using, its defrost speed was more obvious; Built-in distributing fin makes the fluid in the pressure-bearing pipe flow to occur turbulent condition easily, seethe with excitement and fully heat exchange at short notice, a large amount of colds is in the super cooled sect heat exchange, reduced the cold that extends to gasification, bringing-up section. comparatively speaking, this anti-freeze heat exchanger tube has slowed down the speed of frosting, ice, improve the ability of defrost, ice, and then improved the service efficiency of whole gasifier, thereby can reduce cost of investment.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the structural representation of existing heat exchanger tube.
Fig. 2 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 2, this anti-freeze heat exchanger tube comprises a pressure-bearing pipe 1, the outer wall of pressure-bearing pipe 1 is provided with 4 fins 2, fin 2 radially radially distributes along pressure-bearing pipe 1, the interval is 90 ° between the two adjacent fins, and the inwall of pressure-bearing pipe 1 is provided with several distributing fins 3, and distributing fin 3 is along the radial distribution of radially one-tenth of pressure-bearing pipe 1, form fluid passage 4 in the pressure-bearing pipe 1, need the liquid of gasification in the fluid passage, to flow.Pressure-bearing pipe 1 is an integral body with fin 2 and distributing fin 3, passes through extrusion molding of special purpose extrusion press by aluminium bar.
Because the angle and the spacing of the outer surface fin of this heat exchanger tube are very big, frost or ice are difficult to attached to fin surface, promptly the finned tube surface possessed rapid defrost, the function of the frost that falls, particularly when gasifier was stopped using, its defrost speed was more obvious; Built-in distributing fin makes the fluid in the pressure-bearing pipe flow to occur turbulent condition easily, boiling and fully heat exchange at short notice, and a large amount of colds has reduced the cold that extends to gasification, bringing-up section in the super cooled sect heat exchange.Comparatively speaking, this anti-freeze heat exchanger tube has slowed down the speed of frosting, ice, has improved the ability of defrost, ice, and then improves the service efficiency of whole gasifier, thereby can reduce cost of investment.
More than a kind of anti-freeze heat exchanger tube that the utility model embodiment is provided be described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; part in specific embodiments and applications all can change; in sum; this description should not be construed as restriction of the present utility model, and all any changes of being made according to the utility model design philosophy are all within protection domain of the present utility model.
