Description
Technical field
This utility model relates to chemical process technical field, particularly relates to a kind of oven gas or natural gas etc. rich in steam methane catalyzed conversion stove in the unstripped gas of methane gas composition, and the gas after conversion can be used to synthesize ammonia and synthesizing methanol。
Background technology
Reburner is the visual plant in the oven gas synthesis chemical plant installations such as ammonia and synthesizing methanol。Reburner burner is entered from the unstripped gas of purification section after being preheated, burner is entered after oxygen is preheated, burn in burner, after gas after burning is sufficiently mixed, enter in the reforming catalyst contained in reburner body of heater and carry out conversion reaction, conversion gas through conversion reaction discharges reburner, removes synthesis ammonia or methanol, CH in conversion gas now4Content is less than 0.5%, the reburner structure commonly used now is: the unstripped gas of preheating is imported in body of heater by reburner top, the oxygen enrichment of preheating or pure oxygen are entered non-metallic combustion device by oxygen intake, dispensing orifice on non-metallic combustion device enters in body of heater, combustion reaction is carried out with unstripped gas, conversion reaction is carried out subsequently into beds, finally convert gas and discharged out of the furnace by converting gas outlet, easily produce reburner due to high temperature and burn accident, catalyst is short for service life, and inner member is easily damaged, need often to change, waste manpower and materials, easily have an accident, cause the injury of the person。
Summary of the invention
In order to solve problems of the prior art, the utility model discloses a kind of methane reborner, it is desirable to provide a kind of esy to use, safe and reliable, reburner that thermal insulation is effective。
This utility model is achieved through the following technical solutions:
A kind of methane reborner, including housing, the vacuum heat-insulating layer being located in inner walls and beds, described housing and vacuum heat-insulating layer constitute body of heater, unstripped gas entrance and burner it is arranged at body of heater, burner adopts refractory metal material to make, directly fuel oxygen is sprayed in unstripped gas, flame not with reburner contact internal walls, it is to avoid to reburner inwall produce damage；Set cellular board on the top of described beds and bottom respectively and support platform, improving the dispersion situation of fluid, it is to avoid direct flame contact catalyst, improve the service life of catalyst；Converting gas outlet and be located at the lower section of stove inner support platform, and be provided with control damper converting gas outlet, the design supporting platform improves force-bearing situation, decreases maintenance load, and control damper solves and converts the problem that entraining air stream washes away。
Burn to solve thermometer boss, the problem of thermocouple ejection, improve the security performance of reburner operation, be provided with, at described beds place, the thermocouple thermometer that concave support frame is connected with beds。
Preferably, it is coated with protection against erosion coating in the outlet of described conversion gas。
Preferably, described vacuum heat-insulating layer inwall is coated with high temperature coating。
It is preferred that design for circular hollow bottom described support platform, and support platform sidewall offers multiple through hole。
The beneficial effects of the utility model are: this utility model is rational in infrastructure, easy to use, practical, safe and reliable, catalyst long service life, thermal insulation is effective, extends the service life of reburner, saves manpower and materials, ensure that reburner long-term operation, the unstripped gas system of improve synthesis ammonia, the economic benefit of synthesizing methanol, it is simple to promote。
