Abstract

Provided are a vitrification equipment starting method and starting unit. The vitrification equipment starting method includes: preparing an ignition module; putting the ignition module into a chamber of a low-temperature melting furnace; and performing an ignition operation inside the chamber of the low-temperature melting furnace using the ignition module connected to a high-frequency heating unit outside the low-temperature melting furnace, wherein the ignition module is put into the chamber of the low-temperature melting furnace in an initial state before a form thereof is changed and, when put into the chamber of the low-temperature melting furnace, becomes a variable state in which the form thereof is changed from the initial state and performs the ignition operation.

First claim

1 . A vitrification equipment starting method comprising:
preparing an ignition module; putting the ignition module into a chamber of a low-temperature melting furnace; and performing an ignition operation inside the chamber of the low-temperature melting furnace using the ignition module connected to a high-frequency heating unit outside the low-temperature melting furnace, wherein the ignition module is put into the chamber of the low-temperature melting furnace in an initial state before a form thereof is changed and, when put into the chamber of the low-temperature melting furnace, becomes a variable state in which the form thereof is changed from the initial state and performs the ignition operation.

2 . The method of claim 1 , wherein the low-temperature melting furnace comprises a gate which connects the inside and the outside, the ignition module is put into the low-temperature melting furnace in the initial state via the gate, and the variable state of the ignition module comprises a form expanded larger than a volume of the ignition module in the initial state.

3 . The method of claim 2 , wherein a first volume value of the ignition module, which is a volume value in the initial state, has a value equal to or less than an area value of the gate, and a second volume value of the ignition module, which is a volume value in the variable state, has a value exceeding the area value of the gate.

4 . The method of claim 2 , wherein the ignition module comprises:
an ignition body in the initial state or the variable state; and a storage body accommodating the ignition body in the initial state therein so that the ignition body maintains the initial state.

5 . The method of claim 4 , wherein the ignition body of the ignition module comprises a plurality of joint portions, a rotating portion rotating the joint portions, and an elastic portion fitted over the joint portions and at least a part of the rotating portion to surround an outer surface of the joint portions and at least a part of the rotating portion and provide an elastic restoring force to each of the joint portions of the rotating portion.

6 . The method of claim 4 , wherein the storage body of the ignition module is at least partially destroyed by external force applied in a process of being put into the gate of the low-temperature melting furnace, and the ignition body of the ignition module becomes the variable state as the ignition body is discharged to the outside of the storage body based on the destruction of the storage body.

7 . The method of claim 6 , wherein the storage body comprises any one of rubber, glass, and plastic materials.

8 . A vitrification equipment starting unit comprising an ignition module put into a chamber of a low-temperature melting furnace to perform an ignition operation, wherein the ignition module is put into the chamber of the low-temperature melting furnace in an initial state before a form thereof is changed and, when put into the chamber of the low-temperature melting furnace, becomes a variable state in which the form thereof is changed from the initial state, performs the ignition operation in contact with melt inside the low-temperature melting furnace, and performs the ignition operation inside the chamber of the low-temperature melting furnace while being connected to a high-frequency heating unit outside the low-temperature melting furnace.
