Description
Technical field
The present invention relates to a kind of pressurized machine.
Background technique
Pressurized machine in the present invention is mainly used in the supercharging in liquid nitrogen storage tank, and it is formed by many pressure-bearing pipe UNICOMs, and every root pressure-bearing pipe is provided with multiple fin.In actual applications, liquid nitrogen storage tank comprises inner bag and outer courage, and liquid nitrogen is contained in inner bag, and inner bag top is provided with boost port, and inner bag bottom is provided with gas port and air outlet, and described pressurized machine is serially connected on the path that air outlet is connected with boost port.
Specific works situation is that liquid nitrogen is flowed into pressure-bearing pipe by air outlet, forms air pressure through heat exchange vaporization and enters inner bag by boost port, and then the inner bag supercharging to liquid nitrogen storage tank, and liquid nitrogen press-in gas port is supplied industrial application.
Currently available technology, stable liquid nitrogen flow can be provided with gas port in order to what make liquid nitrogen storage tank, usually 8 fins are fixed by the every root pressure-bearing pipe in pressurized machine, the area of contact of pressure-bearing pipe and air is increased by more number of fins, thus improve the evaporating capacity entering liquid nitrogen in pressurized machine further, finally make pressurized machine provide elevated pressures to the inner bag of liquid nitrogen container.
Simultaneously, existing heat transfer technology always Problems existing be exactly pressure-bearing pipe finned surface easily freeze frosting.When the liquid nitrogen stream of liquid nitrogen storage tank inner bag is through pressurized machine, every root pressure-bearing pipe is provided with 8 fins can have larger heat exchange amount in the starting stage; But after work a period of time, pressure-bearing pipe and finned surface there will be icing frost, and the top of eight fins is owing to forming a cup-like structure, first half frost is piled up gradually and is difficult to eliminate, cause pressure-bearing pipe heat transfer rate straight line to decline.Heat exchanger pressurized effect at the beginning of operation of this structure is remarkable, but surface starts to freeze, pressurized effect afterwards obviously reduces; After running a period of time, the effective heat exchanging part of pressurized machine is only the fin of pressure-bearing pipe bottom.In order to again provide higher pressurized effect, needing to stop liquid nitrogen storage tank work a period of time to thaw, after pressurized machine fin all thaws, again opening liquid nitrogen storage tank and liquid nitrogen supply is carried out to outside.
As can be seen from above situation, currently available technology Problems existing is: traditional liquid nitrogen storage tank pressurized machine cannot work continually and steadily.
Summary of the invention
For the problems of the prior art, the invention provides a kind of liquid nitrogen storage tank pressurized machine of sustainable stable operation.
In order to achieve the above object, technological scheme of the present invention is: a kind of pressurized machine, comprises pressure-bearing pipe and fin, and described fin is fixedly connected with pressure-bearing pipe; It is characterized in that: described fin comprises the first fin and the second fin, between described first fin and horizontal line, angle is 60 to 120 to spend, and between described second fin and horizontal line, angle is-60 to-120 to spend.
Can find out that this practical tool has the following advantages according to such scheme:
The first, eight fin structures are not re-used, but directly adopt the mode that two fins are fixedly connected with pressure-bearing pipe, because angle between the first fin and horizontal line is 60 to 120 to spend, between described second fin and horizontal line, angle is-60 to-120 to spend, after the first fin after liquid nitrogen enters pressure-bearing pipe and the second finned surface frosting are frozen, icing frost reaches constant weight and will come off from fin, thus it is white to ensure that finned surface does not freeze.
The second, on the basis ensureing the basic anti-freezing of fin on pressurized machine pressure-bearing pipe, the pressure of starting voltage supply can be slightly weak, do not affect use, can stablize vaporization after liquid nitrogen flows into pressurized machine in storage tank inner bag simultaneously, and then ensure uninterruptedly to stablize voltage supply for a long time.
Three, technician better comparatively stablizes pressurized effect for reaching, have technology prejudice always, exactly by increasing this technology general knowledge that heat exchange area is raising heat transfer rate, such as number of fins is made 8 or more, and instant invention overcomes this technology prejudice, have employed less fin and but can ensure pressurized effect continually and steadily.
As preferably, between described first fin and horizontal line, angle is 90 degree, and between described second fin and horizontal line, angle is-90 to spend; To be on same straight line when the first fin and the second fin and to be rectilinear with horizontal line, icing frost is the easiest comes off from fin in finned surface institute.
As improvement, described first fin and the second fin are provided with the thin layer for reducing adhesion; Set up the thin layer reducing finned surface adhesion and can further improve the speed that frost on fin comes off, and then improve the pressurized effect of pressurized machine.
As preferably, described thin layer is the nanometer thin rete that amido coatings is made; The nanometer thin rete that amido coatings is made can reduce the corrosion rate of heat exchanging tube further while reducing metal surface adhesion, can improve the working life of vaporizer.
