Technical Field
The utility model relates to an erection equipment technical field of ironmaking hot-blast furnace temperature measurement observation pipe, concretely relates to tilting installation device for ironmaking hot-blast furnace temperature measurement observation pipe.
Background
In the iron-making production of steel plants, the combustion-supporting gas of a blast furnace is preheated in a hot blast stove to reach the optimum temperature for effective production. The hot blast stove is divided into two parts: the combustion chamber and the checker bricks, after the fuel in gas state is combusted in the combustion chamber, hot air passes through the checker bricks to heat the bricks, and the checker bricks are used as a heat exchanger to preheat the air of the blast furnace. The hot air is fed into the blast furnace through a huge hot air pipe. Temperature control in a hot blast stove is very important. The traditional thermocouple for temperature measurement has higher measurement precision and higher reaction speed than a thermocouple, has wide temperature measurement range, is not easy to damage equipment, and is increasingly adopted on a hot blast stove. The infrared thermometer detects the temperature of hot air or the temperature of a refractory wall in the furnace through an observation tube extending into the furnace, and sends a temperature signal to the main control room to participate in the control of production. In the early stage of putting a newly-built hot blast stove into production, building fragments in the stove often fall into the observation pipe after being violently impacted by high-temperature airflow to block the lens, cause measurement interruption, and influence blast furnace production.
At the present stage, if the observation pipe extending into the hot blast furnace wall is installed in a downward inclined mode, the observation pipe can be effectively prevented from being blocked by building fragments, even if the fragments enter the observation pipe, the fragments can automatically fall out, but inclined holes can cause the looseness of a bricked furnace wall refractory brick, the structural surface is damaged greatly, the construction is inconvenient, the safety of the iron-making hot blast furnace is influenced, and therefore the temperature measurement problem must be solved on the premise of not influencing the safety.
