Online blast furnace cooling stave leakage detection device and detection method thereof

Abstract

The invention discloses an online blast furnace cooling stave leakage detection device and a detection method thereof and belongs to the field of cooling stave breakage detection equipment and methods of blast furnace ironmaking processes. The device comprises a main cylinder cavity, a water inlet pipe, a water inlet valve, a transparent dial, a blowdown valve, an exhaust pipe, an exhaust valve, an airbag air collecting pipe, a drainage pipe, a drainage valve, an auxiliary cylinder and an overflow water sealing hole. The water inlet pipe is located on the upper end face of the main cylinder cavity, the water inlet valve is arranged on the water inlet pipe, the exhaust pipe, the exhaust valve and the airbag air collecting pipe are arranged on the upper end face of the main cylinder cavity, the auxiliary cylinder cavity is further arranged in one side of the main cylinder cavity, the main cylinder cavity and the auxiliary cylinder cavity are partitioned through a main / auxiliary cavity partition, and the overflow water sealing hole is further arranged in the lower portion of the main / auxiliary cavity partition; the blowdown valve is arranged on the bottom surface of the main cylinder cavity. By the arrangement, problems continuous monitoring cannot be realized, actual operation is difficult and detection speed is low in the prior art are solved, continuous monitoring can be realized, convenience in operation is achieved, and efficiency in leakage detection is improved.

Description

technical field [0001] The invention belongs to the field of detection of staves in blast furnace ironmaking process, and more specifically relates to an online detection device and detection method for water leakage of a blast furnace stave. Background technique [0002] Regardless of whether it is a large blast furnace or a small and medium-sized blast furnace, half a year after the furnace is opened, the refractory lining protecting the stave will be washed and eroded by the falling charge, slag and rising high-temperature gas flow, and the hot surface of the stave will form slagging skin. Furnace shape, the slag skin falls off, sticks, falls off again, and sticks again in a cycle. Generally, after two to three years of continuous production, the furnace bosh, furnace waist, and furnace stave begin to be damaged. As the smelting time of the blast furnace goes on, the water leakage phenomenon will obviously increase. If it is not discovered in time and scientifically mana...
