The heat tracing composite pipe is characterized by further comprising a heat-conduction protection layer which is wrapped on the sample gas pipe; and through the heat-conduction protection layer, the temperature distribution on the sample gas pipe is uniform. The heat tracing composite pipe has the advantages of uniform temperature, long-distance tracing and the like.
Description
Technical field
The present invention relates to the hot composite pipe of a kind of companion, especially a kind of hot composite pipe of companion that makes the uniformity of temperature profile on kind tracheae.
Background technique
In online sampling system, after gas is extracted by sampling head, deliver to detecting instrument through the sampling pipe of heating tape companion heat and monitor.TRACER can guarantee not dewfall of kind gas, has guaranteed the authenticity of component.
What at present general heating tape adopted is permanent power electric heating element.The structure of conventional heat traced pipeline is that heating tape directly fits together with the appearance tracheae; The heating tape of heat makes the temperature on appearance tracheae and the contacted one side of heating tape be higher than the temperature of another side; Non-uniform temperature on the feasible appearance tracheae cross section; This just causes the temperature of appearance gas in kind tracheae can not reach needed temperature fully; Or the appearance tracheae too high kind tracheae that makes of temperature on one side damages easily, and then causes some composition in depressed dew of appearance or the appearance gas to be adsorbed, and all brings influence for follow-up analyzing and testing.
Summary of the invention
In order to solve above-mentioned deficiency of the prior art, the invention provides a kind of uniformity of temperature profile, can realize the hot hot composite pipe of companion of long distance companion.
For realizing the foregoing invention purpose, the present invention adopts following technological scheme:
The hot composite pipe of a kind of companion comprises at least one heating tape, at least one kind tracheae, screen layer, thermal insulation layer and outer protective layer, is characterized in:
Said composite pipe also comprises the heat conduction protective layer that is wrapped on kind tracheae, and said heat conduction protective layer makes the uniformity of temperature profile on kind tracheae.
Further, said heat conduction protective layer is the metal heat-conducting protective layer.
Further, said metal heat-conducting protective layer is the metal flexible band.
As preferably, said metal heat-conducting protective layer is aluminium foil or Copper Foil.
Further, said heating tape is parallelly connected heating tape.
As preferably, said parallelly connected heating tape is PTC heating tape or parallelly connected permanent power heating tape.
Further, said heating tape is the series connection heating tape.
As preferably, said series connection heating tape is MI heating tape or nickel chrome wire.
Further; The hot composite pipe of said companion also comprises temperature transducer and control unit; Said temperature transducer is arranged between heat conduction protective layer and the screen layer, and said temperature transducer links to each other with control unit, and said control unit is according to the temperature of the temperature signal control heating tape of temperature transducer feedback.
The present invention compared with prior art has following beneficial effect:
1, uniformity of temperature profile
Parcel layer of metal protection heat-conducting layer on the appearance tracheae, the metal coating heat-conducting layer can make outside heat be transmitted to equably in kind tracheae, and heat was evenly distributed in one week of appearance tracheae, and this has just guaranteed the uniformity of appearance temperature degree in the appearance tracheae.
2, realize that length is apart from high temperature companion heat
During series connection heating wires such as heating tape employing MI cable of the present invention, can realize high temperature companion heat, not have the pressure drop situation owing to the series connection heating tape simultaneously, this just makes heat traced pipeline can realize that long distance companion is hot.

Embodiment
Embodiment
See also Fig. 1, the hot composite pipe of a kind of companion comprises a heating tape 1, appearance tracheae 2, heat conduction protective layer 3, screen layer 4, thermal insulation layer 5 and an oversheath 6.
Parcel is twined by heat conduction protective layer 3 in the outside of appearance tracheae 2, and screen layer 4 twines appearance tracheae 2 parcels that wrap up with heating tape 1 with by heat conduction protective layer 3, and the outer installment of screen layer 4 sets gradually thermal insulation layer 5 and oversheath 6.
Through heat conduction protective layer 3 is set, the heat on the heating tape 1 at first passes to heat conduction protective layer 3, and heat is evenly distributed on heat conduction protective layer 3, and heat conduction protective layer 3 has improved the uniformity of appearance tracheae 2 one all temperature again with heat transferred appearance tracheae 2.
The appearance tracheae is not wrapped up the heat conduction protective layer outward simulates with the heat transfer situation that is enclosed with the composite pipe of heat conduction protective layer; See also Fig. 2～Fig. 5; Can draw, the composite pipe that is enclosed with the heat conduction protective layer is more even than the heat transfer of the composite pipe that does not wrap up the heat conduction protective layer.
Said heat conduction protective layer 3 can heat conduction and is flexible good, can be the metal heat-conducting protective layer, for the metal flexible band of good heat conductivity, like aluminium foil, Copper Foil etc.
Said heating tape is parallelly connected heating tape or series connection heating tape;
When adopting parallelly connected heating tape, can realize the uniformity of kind tracheae one all temperature, and accompany hot temperature range, accompany hot length to can be 70 meters generally at the 65-140 degree;
When adopting the series connection heating tape, not only can realize the uniformity of kind tracheae one all temperature, accompany hot temperature not wait, accompany hot length can reach hundreds of rice, can realize high temperature and long distance companion's heat from the 180-600 degree.
As preferably, parallelly connected heating tape can be PTC heating tape, parallelly connected permanent power heating tape etc.;
As preferably, the series connection heating tape can be MI cable, nickel chrome wire etc.
When adopting parallelly connected heating tape PTC, accompany hot temperature to control by heating tape itself;
When adopting other heating tapes, also need outside temperature control component controls temperature; The hot composite pipe of then said companion also comprises temperature transducer and control unit; Said temperature transducer is arranged between heat conduction protective layer 3 and the screen layer 4; Said temperature transducer links to each other with control unit, and said control unit is according to the temperature of the temperature signal control heating tape of temperature transducer feedback.
Further; When a plurality of heating tapes and/or a plurality of kinds of tracheaes were arranged in the composite pipe, parcel heat conduction protective layer got final product on the appearance tracheae, is that all kinds tracheae is bundled together as for the heat conduction protective layer; Still each kind of parcel tracheae is unimportant separately; As long as an appearance tracheae is wrapped with the heat conduction protective layer, and the heat of heating tape can pass to the heat conduction protective layer, passes to a kind tracheae through the heat conduction protective layer again and gets final product.
Above-mentioned mode of execution should not be construed as the restriction to protection domain of the present invention.Key of the present invention is: at appearance tracheae outerwrap heat conduction protective layer, make heat transfer more even.Under the situation that does not break away from spirit of the present invention, any type of change that the present invention is made all should fall within protection scope of the present invention.
