Abstract
The utility model relates to a combustion-supporting gas heater, which is used for heating combustion-supporting gas. The combustion-supporting gas heater comprises a first heat exchanger, a second heat exchanger, a combustion-supporting gas passage and an inert gas passage, wherein the inertia gas passage is provided with a heater, is connected to the heater after passing through the second heat exchanger and is also connected to the first heat exchanger through the heater; and the combustion-supporting gas passage is connected with a high-temperature technical area through the first heat exchanger and is connected with the second heat exchanger through the high-temperature technical area. The combustion-supporting gas heater disclosed by the utility model indirectly heats the combustion-supporting gas by utilizing inertial gas so as to improve the safety of the combustion-supporting gas heating operation, and has the advantages of stability, reliability and good heating effect.
Description
Technical field
The utility model relates to a kind of heater that is used to heat combustion-supporting property gas.
Background technology
In the prior art, combustion-supporting property gas (like oxygen etc.) when being heated to high temperature (as＞300 ℃), is adopted direct-fired method usually, be about to electric heating tube and insert directly heating in the combustion-supporting property gas.When electric heating tube punctured, there was bigger potential safety hazard in this heating means.
Summary of the invention
The purpose of the utility model provides a kind of combustion-supporting gas heater of the security when improving the heating of combustion-supporting property gas.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of combustion-supporting gas heater is used to heat combustion-supporting property gas, and described combustion-supporting gas heater comprises first heat exchanger, second heat exchanger, combustion-supporting gas path, inert gas path; Described inert gas path is provided with heater, and described inert gas path is connected to described heater through behind described second heat exchanger, and is connected to described first heat exchanger by described heater; Described combustion-supporting gas path is connected to the high-temperature technology district through behind described first heat exchanger, and is connected to described second heat exchanger by described high-temperature technology district.
Preferably, described heater is an electric heater.
The utility model operation principle is: inert gas behind second heat exchanger, get into be heated in the heater temperature required; Get into then in first heat exchanger with behind the combustion-supporting property gas converting heat that feeds wherein and see off; Make combustion-supporting property gas be heated to required temperature; Combustion-supporting property gas after the heating gets into and gets in second heat exchanger, with the heat transferred inert gas after related process is accomplished in the high-temperature technology zone.
Because technique scheme utilization; The utility model compared with prior art has advantage: because the utility model adopts the combustion-supporting property of inert gas indirect gas; Improved the security of heating combustion-supporting property gas, device is stable, reliable, and heats is good.
Description of drawings
Accompanying drawing 1 is the structural representation of the combustion-supporting gas heater of the utility model.
In the above accompanying drawing: 1, first heat exchanger; 2, heater; 3, high-temperature technology district; 4, second heat exchanger.
The specific embodiment
Below in conjunction with embodiment shown in the drawings the utility model is further described.
Embodiment one: shown in accompanying drawing 1.
A kind of combustion-supporting gas heater is used to heat combustion-supporting property gas (like oxygen etc.).
The combustion-supporting gas heater comprises first heat exchanger 1, second heat exchanger 4, combustion-supporting gas path, inert gas path.The inert gas path is provided with heater 2, and the inert gas path is connected to heater 2 after through second heat exchanger 4, and is connected to first heat exchanger 1 by heater.The combustion-supporting gas path is connected to high-temperature technology district 3 after through first heat exchanger 1, and is connected to second heat exchanger 4 by high-temperature technology district 3.Wherein, heater 2 is an electric heater.
This combustion-supporting gas heater in use; Inert gas is heated by the combustion-supporting gas behind the hot operation through second heat exchanger 4; Heater via 2 is heated to temperature requiredly again, gets in first heat exchanger 1 and the heat exchange of combustion-supporting gas gas, sees system off after heat is passed to combustion-supporting gas.
Combustion-supporting gas is heated to temperature required by inert gas through first heat exchanger 1, after entering high-temperature technology district 3 accomplishes related process, send into second heat exchanger 4 and reclaim heats, and heat is passed to combustion-supporting gas, sends into next equipment then.
The foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.
Claims (2)
1. a combustion-supporting gas heater is used to heat combustion-supporting property gas, and it is characterized in that: described combustion-supporting gas heater comprises first heat exchanger, second heat exchanger, combustion-supporting gas path, inert gas path; Described inert gas path is provided with heater, and described inert gas path is connected to described heater through behind described second heat exchanger, and is connected to described first heat exchanger by described heater; Described combustion-supporting gas path is connected to the high-temperature technology district through behind described first heat exchanger, and is connected to described second heat exchanger by described high-temperature technology district.
