Abstract

Disclosed herein are a treatment apparatus and method for a waste steam generator, and an installation method of a treatment apparatus for a waste steam generator. The treatment apparatus includes a cutting part for cutting a body of a waste steam generator, a driving part for driving the cutting part, and a support frame for supporting the cutting part and the driving part, wherein the support frame is coupled to an outer peripheral surface of the body of the waste steam generator in a divided state, and the cutting part is driven and cuts the body in a state in which the support frame is coupled to the outer peripheral surface of the body. Consequently, since the treatment apparatus is easily moved and installed, an installation time of the treatment apparatus may be shortened and an exposure time of a worker can be reduced.

First claim

an electric supply module for supplying electric power to the driving part and the frame driving part, the electric supply module comprises an electric power supply rail coupled to the other surface of the main frame, a rail connection part maintained and rotated in a state of coming into contact with the electric power supply rail when the rotation frame is stopped and rotated, and a connection part connecting the rail connection part to the rotation frame, and the driving part and the frame driving part are electrically connected to the electric supply module through the rotation frame.

2. The treatment apparatus according to claim 1 , wherein the support frame is divided into four portions, and the four portions are coupled to the outer peripheral surface of the body in the four locations.

3. The treatment apparatus according to claim 1 , wherein the cutting part is provided in plural numbers and is a circular cutter having a circular saw.

4. The treatment apparatus according to claim 3 , wherein the plurality of cutting parts is spaced apart from each other and pass along a cutting path.

5. The treatment apparatus according to claim 4 , wherein each of the cutting parts comprises a first cutter and a second cutter, and the first and second cutters are installed so as to have the same central axis and such that circular surfaces of the respective first and second cutters face each other and cutting paths of the respective first and second cutters are parallel to each other.

6. The treatment apparatus according to claim 4 , wherein each of the cutting parts comprises first and second cutters having the same cutting path, and the second cutter repeatedly passes along the cutting path along which the first cutter passes.

7. The treatment apparatus according to claim 6 , wherein the first cutter has a greater cutting width (t) than a cutting width (t 1 ) of the second cutter, the first cutter has a cutting depth from the outer peripheral surface of the body to a preset cutting depth (H), and the second cutter has a cutting depth from the preset cutting depth (H) to an inner peripheral surface of the body.

8. The treatment apparatus according to claim 7 , wherein the driving part drives the cutting part in a first direction in which the cutting part rotates, in a second direction in which the cutting part is moved toward the outer peripheral surface of the body, and in a third direction in which the cutting part is spaced apart from the body.

9. The treatment apparatus according to claim 1 , wherein the rotation frame is infinitely rotated when the electric power is supplied thereto through the electric supply module, and the driving part and the frame driving part are controlled in a wireless manner.

10. The treatment apparatus according to claim 1 , further comprising an injection unit installed on the rotation frame, and the injection unit comprises an injection nozzle for spraying cutting oil in a mist form, a pressure supply part supplied with the electric power from the electric supply module so as to provide an injection pressure of the cutting oil, and an oil tank for storing the cutting oil.

11. The treatment apparatus according to claim 1 , further comprising a movable installation jig which supports the support frame at a lower portion and is separated when the support frame is moved and then coupled to the body.

12. A treatment method for a waste steam generator, the method comprising:
