Induction coil cooling pressure-bearing system for induction heating equipment

Abstract

The invention discloses an induction coil cooling pressure-bearing system for induction heating equipment, comprising a pressure vessel and a heating induction coil. The heating induction coil penetrates through the pressure vessel, and comprises an inner coil section located in the pressure vessel and an outer coil section located outside the pressure vessel. The outer coil section comprises an exhaust coil section and an intake coil section. A cooling medium is arranged in the heating induction coil, and the cooling medium is a gas which is the same with or similar to the pressurized gas ofthe pressure vessel. The induction coil cooling pressure-bearing system for induction heating equipment further comprises a first air pressure detection pipeline connected with the exhaust coil section and a second air pressure detection pipeline connected with the pressure vessel, and the first air pressure detection pipeline is connected with the second air pressure detection pipeline through adifferential pressure gauge. The induction coil cooling pressure-bearing system for induction heating equipment is disclosed in order to solve the technical problem that the induction heating in the prior art can be hardly applied to high-pressure and ultrahigh-pressure equipment and is of poor safety.

Description

technical field [0001] The invention relates to the technical field of induction heating equipment, in particular to an induction coil cooling pressure bearing system for induction heating equipment. Background technique [0002] Induction heating is a heating method widely used in the steel smelting industry. Later, it was used in deposition furnaces, high-temperature furnaces and other fields due to its simple structure. The traditional induction coil design is generally wound with copper tubes, and cooling water is supplied in the middle for cooling. However, the pressure-bearing capacity of copper tubes is weak, so they cannot be used in high-pressure and ultra-high-pressure equipment. At the same time, there is a risk of leakage of copper tube cooling water, especially for high-temperature equipment with graphite materials inside. The leaked water will react with graphite materials and generate a large amount of water. Combustible gas will lead to catastrophic consequen...
