Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] like figure 1 As shown, this explosion-proof cooling and purification device for hydrogen reduction furnace of the present invention is mainly composed of spray water inlet pipe 1, spray water jacket 2, explosion-proof buffer chamber 3, cooling water jacket 4, water supply pipe 5, exposure The buffer tank 6, the float valve 7, the overflow pipe 8, the U-shaped connecting pipe 9 and the sewage pipe 10 are composed. The spray water jacket 2 is arranged on the upper part of the explosion-proof buffer chamber 3, and its inner jacket 21 communicates with the tail gas pipe of the hydrogen reduction furnace, and the wall of the inner jacket 21 is designed with several small holes 211. The spray water inlet pipe 1 is connected to the outer coat 22 of the spray water jacket 2 and communicates with the interlayer space between the inner jacket 21 and the ...

Abstract

The invention provides an anti-explosion cooling purifying device for a hydrogen reducing furnace, mainly comprising a spray water inlet pipe, a spray water sleeve, an anti-explosion buffering cavity, a cooling water sleeve, a water-supplying pipe, an open buffering water tank, a floating ball valve, a U-shaped communicating pipe and a waste discharging pipe. The spray water inlet pipe and the spray water sleeve are used for rinsing and cooling tail gas from the hydrogen reducing furnace for reducing the temperature of the tail gas so as to eliminate part of dust, ammonia and moisture in hydrogen as well as reduce the burden of the hydrogen recovering and purifying system; and the anti-explosion buffering cavity, the U-shaped communicating pipe and the open buffering water tank and the water column are used for isolating air in the reducing furnace from air outside so as to achieve the functions of water sealing, pressure releasing and anti-explosion. The invention is suitable for various hydrogen reducing furnaces and has the advantages of reasonable design, simplicity and practicability, safety and reliability as well as evident effect.

Description

technical field [0001] The invention relates to a tail gas treatment device for a hydrogen reduction furnace, in particular to an explosion-proof cooling and purification device for a hydrogen reduction furnace. Background technique [0002] Generally, the hydrogen reduction furnace needs to send the high-temperature, high-humidity, and high-dust tail gas mainly discharged from hydrogen to the hydrogen purification system for recovery and purification treatment, and then recycle, such as the hydrogen reduction furnace for powder reduction of tungsten, molybdenum, and cobalt. . For safety reasons, an explosion-proof device is usually connected to the exhaust port of the hydrogen reduction furnace, and then the tail gas is sent to the hydrogen purification system through the pipeline. The explosion-proof principle of the connected explosion-proof device basically adopts a pressure relief port sealed with a rubber or a burst-proof disc. When the pressure in the furnace suddenl...
