Abstract
The utility model discloses a portable blast furnace cooling water temperature detection device, which is mainly used for monitoring the temperature of circulating cooling water of a blast furnace. The device comprises a thermal resistor, and is characterized in that: the thermal resistor penetrates through a compression nut, a connecting piece and a ball valve in turn and is arranged in the compression nut, the connecting piece and the ball valve; the ball valve is connected with the compression nut through the connecting piece; the connecting piece is a hollow pipe with external threads; and a filler is filled between the connecting piece and the thermal resistor. By measuring the water temperature at the cooling water inlet of the blast furnace and the water temperature at the cooling water outlet of the blast furnace, the working state of a liner of a blast furnace body can be judged, the thickness of a brick liner, the stability of a slag crust and the working safety of a cooling element can be calculated, a basis for operation in the blast furnace is provided, and the device particularly has important significance for judging whether the working condition of a hearth is safe by calculating the heat flow intensity of a cooling wall through the temperature rise of the cooling water when the brick liner of the hearth in the later stage of campaign is corroded and the temperature is raised.
Description
Technical field
The utility model is mainly used in the water temperature detection of blast furnace recirculated cooling water, is specifically related to a kind of portable blast-furnace cooled water temperature detector.
Background technology
The modern blast furnace body extensively adopts soft water closed cycle methods for cooling, and to the shaft cascaded structure, every road arm all is connected with some cooling elements from furnace foundation in employing usually; Because soft water closed cycle form; Thermal load in the measuring water temperature difference monitoring stove is caused difficulty, and especially the cupola well position needs the areal survey water temperature difference; Every road cooling-water duct water yield is more than 20t/h, and temperature rise just often has only several degrees centigrade of zero points.Usually adopting discharges water from the vapor cock of the water-in and water-out external connecting pipe of required measurement cooling element measures the blast-furnace cooled water water temperature.
Interfere because water displacement constitutes closed circuit circulatory system when big, the arm water yield changes, water displacement hour, the ambient temperature influence is big, and is also influential to the arm water yield, the water temperature error of surveying very big, can not reflect real thermal load of blast furnace and heat flow rate per unit area.
Summary of the invention
For the accurate temperature of areal survey blast furnace closed circuit circulatory system water coolant, the utility model provides a kind of portable blast-furnace cooled water temperature detector.
The utility model comprises hot resistance; It is characterized in that hot resistance passes hold-down nut, web member, ball valve successively and is arranged in hold-down nut, web member, the ball valve; Be connected through web member between ball valve and the hold-down nut; Web member is filled with filler for having externally threaded hollow tube between web member and the hot resistance.
Described hot resistance is 0～99.9 ℃ of PT1000 type of XM2000B digital thermometer hot resistance.
In being inserted in the water coolant through the water coolant joint outer part probe of the hot resistance of the utility model, vapor pipe is connected with ball valve, waits for for 5 seconds, just can measure the water temperature that this water coolant joint outer part goes out.
Through the water temperature of measurement blast-furnace cooled water water-in and the water temperature of blast-furnace cooled water water outlet; Can judge the blast-furnace body liner working order, calculate the security of bricking thickness, slag crust stability, cooling element work; Giving to operate in the State of Blast Furnace provides foundation, especially arrives stove labour later stage brick lining and corrodes, when temperature raises; The cooling stave heat flow rate per unit area is calculated in temperature rise through with water coolant, and whether safety is significant to judge the cupola well operating mode.
