Problems solved by technology

[0005] However, there are obvious deficiencies in the ignition method: when the damaged cooling equipment has a large damage surface and the water leaks for a long time, the heat in the furnace will be transferred to the cooling water in the stave water pipe, resulting in the formation of a large amount of water vapor in the cooling water. not easy to ignite

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 As shown, the embodiment of the present invention includes a joint 1 , a water pipe 2 , a valve 3 , a short connection 4 , a pressure gauge 5 , a cover plate 6 , a drain cylinder 7 , a spring 8 , and a sealing plate 9 .

[0022] Specifically, the joint 1 is used to connect to the cooling water pipeline of the blast furnace cooling equipment. Preferably, the joint 1 is a quick joint. Generally speaking, the blast furnace cooling equipment has a water inlet valve and a water outlet valve, and a three-way valve is installed between the water inlet valve and the cooling equipment to switch between soft water and industrial water. When checking whether a cooling device is damaged, the joint 1 of this embodiment is connected to the three-way valve for leak checking. The size of the joint 1 is selected according to...

Abstract

The invention provides a blast-furnace cooling equipment leakage detecting device. The blast-furnace cooling equipment leakage detecting device comprises a connector, a water pipe and a pressure meter, wherein the connector is used for being connected to a cooling water pipeline of blast-furnace cooling equipment, one end of the water pipe is connected to the connector, and the pressure meter is connected to the other end of the water pipe. When the blast-furnace cooling equipment leakage detecting device is used, if the pressure meter relieves pressure, it is shown that the blast-furnace cooling equipment is damaged and subjected to water leakage; otherwise, it is shown that the blast-furnace cooling equipment is not subjected to water leakage. The blast-furnace cooling equipment leakage detecting device can detect leakage easily, efficiently and accurately. In addition, the blast-furnace cooling equipment leakage detecting device has the advantages of being simple in structure and convenient to carry and use.

Description

technical field [0001] The invention relates to the technical field of leak detection for water cooling equipment, in particular to a leak detection device for blast furnace cooling equipment. Background technique [0002] As we all know, blast furnace cooling equipment includes cooling staves, furnace bottom water-cooled pipes, large tuyere sets, middle and small tuyere sets, and hot blast valves and air mixing valves for hot blast stoves. The stave water pressure of the current medium-sized and large blast furnaces is generally not lower than 0.8Mpa. If the stave is damaged and not found in time, a large amount of water will leak into the furnace, which may cause the furnace temperature to cool down, or cause the hearth to freeze. Lead to a vicious production accident in the blast furnace. [0003] The large, middle and small tuyeres mentioned above are also cooled by water. The water pressure of the small and middle tuyeres is generally not lower than 1.6Mpa in medium an...
