Description
Technical field
The present invention relates to photo-thermal power generation field, especially a kind of composite pipeline being connected with slot type thermal-collecting tube two ends.
Background technology
At present, in industries such as photo-thermal power generation, chemical industry, heat supply, clothes, machineries, the medium of carrying in pipeline has middle high-temperature-hot-water, steam, high temperature oil plant, high temperature industrial chemicals etc., for reducing pipeline thermal loss, pipeline appearance need to be incubated, Basic practice is coated heat-preservation cotton on pipeline surface, and outside is coated with aluminium sheet, color steel or stainless steel again, plays the effects such as windproof, rain and snow;
Above-mentioned pipeline medium has continuous-flow work, has discontinuous flow work, and particularly, when the medium in pipeline stops flowing work, some medium can produce cooling solidification phenomenon, and in this case, the medium in pipeline needs heat temperature raising, avoids solidifying.At present this problem is also better solved, band is served unexpected trouble sometimes.
If the liquid of carrying in pipe is oils, when leaking, holds oil plant fire hazardous, when environment temperature is too low, easily cause that the oil plant in pipeline solidifies, generally for avoiding medium to solidify, conventionally at the outer surface of pipeline, be wound around heater strip or heating tape, but the outer pipeline of oil does not generally allow to use the pyrophoric heater block of easy product, avoids breaking out of fire; Solution is mainly pre-anti-leak at present, the restorative procedures such as repair welding that quit work, drain the oil when there is accident, and other does not have good solution.
The place that need to rotate for some, main use is metal hose at present, has some shortcomings, as function singleness, the insulation that is not easy to do, or insulation produces certain obstruction etc. to rotation.
Summary of the invention
The technical problem to be solved in the present invention is: propose the solar light-heat power-generation universal directional multifunctional multiple tube that a kind of and slot type thermal-collecting tube two ends are connected, have the functions such as insulation, heating, thermometric.
The technical solution adopted in the present invention is: a kind of solar light-heat power-generation universal directional multifunctional multiple tube, comprises and metal inner pipe and the metal outer pipe of socket between described metal inner pipe and metal outer pipe, be provided with the bracing frame for keeping space between jaw elements; In described metal outer pipe, be provided with air inlet and gas outlet; Between described metal inner and outer pipe, be connected with high-pressure pipe.
Specifically, metal outer pipe of the present invention and metal inner pipe are bellows bending on any direction within the scope of 360 °.The place that need to rotate at some like this, pipeline can rotate arbitrarily as required and can not damage.
In order to reduce the heat radiation of metal inner pipe, metal outer pipe inner surface entirety of the present invention is coated with the coat of metal.This coat of metal can be silver layer, aluminium lamination or other any coat of metal.
Further say, the present invention is fixed with temperature probe at the outer surface of described metal outer pipe, and described temperature probe does not contact with metal inner pipe, but temperature probe can directly be measured the temperature of metal inner pipe.
Metal outer pipe outer surface of the present invention is axially provided with groove, described groove at the outer surface of metal outer pipe along circumference axially parallel.In this groove, can place data wire or other electric wire, after installing, overall appearance is cleaner and tidier, attractive in appearance.
Between inside and outside jaw elements of the present invention, can be vacuum, inert gas or other high-temperature gas, while being vacuum state between pipeline, can be incubated, medium in can heating pipe line while being filled with hot-air or other gas, can play the effect of flame-proof explosion-proof while being filled with inert gas.
The invention has the beneficial effects as follows: the present invention has insulation, heating, thermometric, pressure-bearing, tension, anti-leak, the complex function such as explosion-proof, high temperature resistant, corrosion-resistant, this composite pipeline can be connected with slot type thermal-collecting tube two ends in photo-thermal power generation well, meets the multiple requirement of this position pipeline; Function is many, wide accommodation, simple in structure, easy for installation, the life-span is long.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1;
In figure: 1, metal inner pipe; 2, air inlet; 3, metal outer pipe; 4, high-pressure pipe; 5, temperature probe; 6, bracing frame; 7, gas outlet; 8, groove.
The specific embodiment
The present invention is further detailed explanation with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1, 2, a kind of solar light-heat power-generation universal directional multifunctional multiple tube, comprises and metal inner pipe 1 and the metal outer pipe 3 of socket between metal inner pipe 1 and metal outer pipe 3, is provided with the bracing frame 6 for keeping space between jaw elements; In metal outer pipe 3, be provided with air inlet 2 and gas outlet 7; Between described metal inner and outer pipe, be connected with high-pressure pipe 4.Metal outer pipe and metal inner pipe are bellows bending on any direction within the scope of 360 °.
The outer surface of metal outer pipe 3 is fixed with temperature probe 5, and temperature probe 5 does not contact with metal inner pipe 1, but temperature probe can directly be measured the temperature of metal inner pipe.Metal outer pipe outer surface is axially provided with groove 8, groove at the outer surface of metal outer pipe along circumference axially parallel.
When the medium in metal inner pipe 1 need to be incubated, first close air inlet 2, from gas outlet 7, vacuumize, when vacuum reaches certain numerical value scope, can make between metal inner pipe 1 and metal outer pipe 3 heat conduction and thermal convection current greatly reduce, thereby the medium in metal inner pipe 1 is played to insulation object;
When the medium in metal inner pipe 1 (nonflammable) need to heat, open air inlet 2 and gas outlet 7, from air inlet 2, add high temperature air or steam to heat metal inner pipe 1 outer surface, heat passes to the medium in pipe by metal inner pipe 1 surface, plays heating object;
When the medium in metal inner pipe 1 (inflammable) need to heat, open air inlet 2 and gas outlet 7, from air inlet 2, add high temperature nitrogen or other inert gas to heat inner tube 1, heat passes to the medium in pipe simultaneously, plays heating object; Even if the interior inflammable dielectric leakage of inner tube 1 is also difficult for occurring burning or blast under inert gas shielding;
When metal inner pipe 1 adds high-temperature medium, metal inner pipe 1 meeting rapid expansion, and the corrugated portion of metal outer pipe 3 can be opened simultaneously, avoids by drawing crack; When the fluid temperature of metal inner pipe 1 reduces, inner tube 1 can constantly be shunk, and the corrugated portion of metal outer pipe 3 is also along with compressed and not damaged;
When the medium needs in pipeline are emptying, open high-pressure pipe 4, the inert gas that is filled with certain pressure can be discharged the medium of pipeline, thus protection pipeline or medium.
Just the specific embodiment of the present invention of describing in above description, various not illustrating is construed as limiting flesh and blood of the present invention, person of an ordinary skill in the technical field read after description can to before the described specific embodiment make an amendment or be out of shape, and do not deviate from essence of an invention and scope.
