Embodiment Construction

[0010] Such as figure 1 as shown,

[0011] The present invention consists of an intermediate frequency furnace 1, a water seal 2 for isolating the hydrogen discharged from the intermediate frequency furnace from the outside air, a gas-water separator 3 for removing moisture in the hydrogen discharged from the water seal, and a hydrogen recovery treatment system 4 It consists of an intermediate frequency furnace 1, a water seal 2, a gas-water separator 3, and a hydrogen recovery treatment system 4 which are sequentially connected through pipelines.

[0012] In addition, the gas-water separator 3 and the water seal 2 are connected through a return pipe 5 . The upper end of the water seal 2 is connected with the water supply pipe 6, and the lower end is also connected with the drain pipe 7.

[0013] The hydrogen gas discharged from the intermediate frequency furnace 1 enters the water seal 2, and the hydrogen gas is cooled by the water seal 2 and then input into the gas-water s...

Abstract

The invention discloses a hydrogen reclaiming device for a medium frequency furnace, and relates to a hydrogen reclaiming device for the medium frequency furnace for producing tungsten and molybdenum. The hydrogen reclaiming device for the medium frequency furnace comprises the medium frequency furnace, and a water seal which is used for isolating hydrogen exhausted out of the medium frequency furnace from ambient air, and also comprises a gas-water separator which is used for removing the moisture in the hydrogen exhausted out of the water seal, and a hydrogen reclaiming processing system, wherein the medium frequency furnace, the water seal, the gas-water separator and the hydrogen reclaiming processing system are annularly connected with each other in turn through pipelines. The water seal in the hydrogen reclaiming device for the medium frequency furnace not only is used for isolating the hydrogen exhausted out of the medium frequency furnace from the ambient air, but also has the function of explosion protection and pressure relief; the gas-water separator is used for separating the moisture in the hydrogen exhausted out of the water seal; and the hydrogen reclaiming processing system reclaims the hydrogen which is subjected to gas-water separation by the gas-water separator, conveys the hydrogen to the medium frequency furnace for use, and has the functions of energy conservation and consumption reduction.

Description

technical field [0001] The invention relates to a hydrogen recovery device, in particular to a hydrogen recovery device for an intermediate frequency furnace used to produce tungsten and molybdenum. Background technique [0002] The intermediate frequency furnace is an important equipment for the production of tungsten and molybdenum. When the intermediate frequency furnace is working, it usually fills the furnace with hydrogen to form a hydrogen protective sintering atmosphere. In the existing production process, the exhausted hydrogen is usually ignited and burned, which not only wastes the hydrogen seriously, increases the production cost, but also increases the hidden danger of unsafe production. Contents of the invention [0003] The object of the present invention is to provide a hydrogen recovery device for an intermediate frequency furnace that reduces production costs and eliminates production safety hazards. [0004] The invention includes an intermediate freque...
