Description
Изобретение относитс к угольной промышленности и касаетс измерени температуры воздуха в стволе шахты или рудника , обогреваемом с помощью калорифера.The invention relates to the coal industry and concerns the measurement of air temperature in a mine shaft or mine heated by an air heater.
Известен способ измерени температуры воздуха в стволе шахты, обогреваемом калорифером, заключаюшийс в непосредственном контроле температуры в стволе шахты с помощью датчиков 1.There is a method of measuring air temperature in a shaft heated by a heater, which consists in directly monitoring the temperature in a shaft using sensors 1.
Недостатком известного способа вл етс сложность процесса измерени в св зи с тем, что используемые дл непосредственного измерени в стволе датчики необходимо выполн ть взрыво- и искробезопасными, что приводит к погрешност м измерени .A disadvantage of the known method is the complexity of the measurement process due to the fact that the sensors used for direct measurement in the barrel must be made explosion-proof and intrinsically safe, which leads to measurement errors.
Целью изобретени вл етс упрощение процесса измерени и снижение, погрешности за счет использовани средств измерени в обычном исполнении. .The aim of the invention is to simplify the measurement process and reduce the error due to the use of the measurement means in a conventional design. .
Это достигаетс тем, что измер ют температуру наружного воздуха на входе калорифера , температуру нагретого воздуха на выходе калорифера, относительный расход воздуха, проход щего через калорифер, иThis is achieved by measuring the outside air temperature at the inlet of the heater, the temperature of the heated air at the outlet of the heater, the relative flow rate of the air passing through the heater, and
определ ют температуру воздуха в стволе шахты, исход из следующего соотношени :determine the temperature of the air in the shaft, based on the following relationship:
tca,a (ta-ti) gj+ ti, гдet|,t2, ttmg- соответственно температура нуржного воздуха, нагретого воздуха и в стволе шахты;tca, a (ta-ti) gj + ti, get |, t2, ttmg-, respectively, the temperature of the fresh air, the heated air and in the shaft of the shaft;
1 - относительный расход воздуха , проход щего через калорифер;1 is the relative flow rate of air passing through the heater;
GK и Ощ-расход воздуха в единицу времени соответственно через ка.торифер по стволу шахты.GK and Osch-air flow per unit of time, respectively, through ka.orifer on the shaft of the mine.
На чертеже показана функциональна схема, реализующа предлагаемый способ. Способ измерени температуры воздуха в стволе шахты основан на установленной физической зависимости между температурой воздуха в стволе шахты и величинами, доступными измеренинэ в месте расположени калорифера.The drawing shows a functional diagram that implements the proposed method. The method of measuring the air temperature in the shaft is based on the established physical relationship between the air temperature in the shaft and the values available for measurement at the location of the heater.
Эта зависимость описываетс уравнением теплового баланса в смесительной камере калориферной установки .. b-C-GK-trC-G, t;,-C-G -trC-G, где ti, iz и t(,p,g - температура наружного воздуха на входе в калорифер нагретогоThis dependence is described by the equation of heat balance in the mixing chamber of the heater unit. BC-GK-trC-G, t;, - CG -trC-G, where ti, iz and t (, p, g is the outside air temperature heated
