Description
Technical field
The present invention relates to a kind of cross temperature measurer of the band warning function that can change online, belong to metallurgy industry ironmaking technology field.
Background technology
Cross temperature is the device being widely used in blast furnace roof thermometric, and its effect is the change of Real-Time Monitoring blast furnace top gas temperature, for blast furnace operating and production provide guidance.Usually build at blast furnace and be arranged on blast furnace roof position period, carry out between turn(a)round at blast furnace, 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, several years at most, therefore the long-term stability under cross temperature furnace roof high-temperature and high-pressure conditions is used and propose high requirement.Based on the result of cross temperature, can the change of anticipation blast furnace production process, technician's operating blast furnaces for scene provides important data basis, is the important means disclosing high temperature, high pressure, the various physicochemical change of airtight high furnace interior, is the important device maintaining 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 the environment for use of outside (i.e. top gas), makes thermopair directly can contact blast furnace gas.Be applied in blast furnace temperature-measuring process at cross temperature measurer, thermopair stretches out from the tapping of cross temperature measurer, directly contacts the High Temperature High Pressure coal gas in blast furnace.But, when using cross temperature, all multiple enterprises all face a common problem: due to cross temperature be subject to the erosion of continuous high temperature gas, the impact etc. of iron-containing charge causes lasting thermal stresses and mechanical stress, the two cross action, affect very large on the service life thermopair that particularly its internal independence is installed of cross temperature measurer, the active time of part thermopair only can maintain 3-6 month mostly, even shorter.When after thermocouple break, due to the overall tightness of blast furnace, thermopair cannot be changed in time, and thermopair is the main part of cross temperature, be the device of direct measuring tempeature, after thermocouple break, 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, warm high pressure gas high in blast furnace outwards sprays along the tapping of above-mentioned cross temperature and thermopair passage, will cause gas leak, easily causes great loss of life and personal injury; In addition on the one hand, the thermopair of involuntary conversion cross temperature also will cause blast furnace maintenance outside the plan, stopping production, cause great financial loss to enterprise.As can be seen here, can change online rapidly the personnel safety of thermopair to site operation personnel of cross temperature, enterprise normal production most important.
Summary of the invention
Object: in order to overcome the deficiencies in the prior art, the invention provides a kind of cross temperature measurer of the band warning function that can change online, can after the thermocouple break of cross temperature, can carry out immediately changing thermopair online, rapidly, and guarantee that High Temperature High Pressure coal gas does not leak, do not affect the normal production of blast furnace; Simultaneously with temperature pre-warning function, when abnormal conditions appear in the gas temperature of blast furnace roof, can give warning in advance; Have employed wireless data transmission function simultaneously, simplify the various connection problems of thermopair in design, installation process to greatest extent.
