Embodiment Construction

[0016] The specific embodiments of the invention will be described in detail below in conjunction with the accompanying drawings.

[0017] figure 1 Shown in the present invention is a flow chart of a helium recovery system for a wire drawing furnace. After the helium is discharged from the drawing furnace, it passes through the helium gas collector and filter, and then passes through the mass flow regulating valve to the low-pressure collection stage. After passing through the low-pressure collection, it leads to the buffer tank. The compressed buffer tank leads to the purification system.

[0018] Such as figure 2 As shown in the present invention, a wire drawing furnace recovery system includes in turn: 1. Helium recovery device; 2. Coarse filter; 3. Precision filter; 4. Solenoid valve; 5. Mass flow regulating valve; 8. Helium vacuum pump; 9. 12. Buffer tank; 10. Pressure regulating valve; 11. Helium compressor.

[0019] After the helium gas is discharged from the drawi...

Abstract

The invention discloses a recovery system for helium in a fiber drawing furnace. The helium passes a helium recovery device connected to the bottom of the fiber drawing furnace and designed independently; the helium is subjected to secondary filtering and low-pressure recovery, enters a buffer tank, and then enters a purification system after leaving the buffer tank and being subjected to high-pressure compression. According to the scheme, the problem of low helium recovery rate and non-ideal recovery effect in the prior art can be solved with the adoption of the independently designed helium recovery device and follow-up recovery technology.

Description

technical field [0001] The invention relates to the field of helium recovery, in particular to a helium recovery system for a wire drawing furnace. Background technique [0002] Helium is an inert gas, colorless, odorless, non-toxic and non-flammable at normal pressure and temperature. It is the substance with the lowest critical temperature found by human beings. It is dark yellow when discharged at low pressure. It is the most difficult to liquefy gas. It is extremely inactive, cannot burn, and is not flame-retardant. Helium will not solidify at absolute zero under normal pressure. Due to such characteristics of helium, helium is widely used in modern industry. During the fiber manufacturing process, helium is used as the protective gas for the heating and softening of the optical rod in the drawing stage. The superconductivity and inert gas characteristics of helium are used to prevent the oxidation of the optical rod, and to exert the thermal conductivity to save energy...
