Description
Technical field
The present invention relates to a kind of cross temperature measurer with warning function that can change online, belong to metallurgy industry ironmaking technology field.
Background technology
Cross temperature is the device that is widely used in blast furnace roof thermometric, and its effect is the variation of Real-Time Monitoring blast furnace top gas temperature, for blast furnace operating and production provide guidance.Conventionally in blast furnace construction, be arranged on blast furnace roof position period, at blast furnace, carry out between turn(a)round, cross temperature measurer just can keep in repair and change, other times generally can not keep in repair, change, 1 year at least, blast furnace maintenance interval, at most the several years, therefore the long-term stability under cross temperature furnace roof high-temperature and high-pressure conditions is used and proposed high requirement.Result based on cross temperature, variation that can anticipation blast furnace production process, for on-the-spot technician's operating blast furnaces provides important data basis, be the important means that discloses high temperature, high pressure, the various physicochemical change of airtight high furnace interior, be the important device that maintains blast furnace stably manufactured.
The main body temperature element of cross temperature measurer is thermopair, and thermopair is placed in the thermopair cavity passage of cross temperature body, and directly communicate with outside environment for use (being top gas) makes thermopair can directly contact blast furnace gas.At cross temperature measurer, be applied in blast furnace temperature-measuring process, thermopair stretches out from the tapping of cross temperature measurer, directly contacts the High Temperature High Pressure coal gas in blast furnace.Yet, when using cross temperature, all multiple enterprises all face a common problem: because cross temperature is subject to the erosion of continuous high temperature gas, the impact of iron-containing charge etc. cause lasting thermal stresses and mechanical stress, the two cross action, very large on the thermopair impact that particularly its internal independence is installed of the service life of cross temperature measurer, the active time of part thermopair only can maintain 3-6 month mostly, even shorter.After thermopair damages, overall tightness due to blast furnace, thermopair cannot be changed in time, and thermopair is the main part of cross temperature, be the device of directly measuring temperature, after thermopair damages, cross temperature measurer will lose temp sensing function, cause temperature measurement data to lose, site operation personnel, owing to lacking temperature data, will have a strong impact on the normal production of blast furnace.If involuntary conversion thermopair, in blast furnace, high warm high pressure gas outwards sprays the tapping along above-mentioned cross temperature and thermopair passage, will cause gas leak, easily causes great loss of life and personal injury; On the one hand, the thermopair of involuntary conversion cross temperature also will cause blast furnace maintenance outside the plan, stopping production ，Gei enterprise to cause great financial loss in addition.As can be seen here, the thermopair of cross temperature can be changed rapidly online most important to the normal production of site operation personnel's personnel safety, enterprise.
Summary of the invention
Object: in order to overcome the deficiencies in the prior art, the invention provides a kind of cross temperature measurer with warning function that can change online, after can damaging at the thermopair of cross temperature, can carry out online immediately, change rapidly thermopair, and guarantee that High Temperature High Pressure coal gas does not leak, do not affect the normal production of blast furnace; With temperature pre-warning function, when abnormal conditions appear in the gas temperature of blast furnace roof, can give warning in advance simultaneously; Adopt wireless data transmission function simultaneously, simplified to greatest extent the various connection problems of thermopair in design, installation process.
