Abstract
The present disclosure provides a reactor cleaning apparatus including: a fixing part having a partial region inserted into a hole formed in an upper portion of a reactor to be coupled to the reactor and fixing a pipe; the pipe inserted into a hole formed in the fixing part, protruding downward from the fixing part, and having a length adjustable in a vertical direction; a spray nozzle provided at a lower end of the pipe; and a screener provided on a lower side surface of the pipe, and a reactor cleaning method using the same.
Claims14
A reactor cleaning apparatus_, comprising:
- a fixing part having a partial region inserted into a hole formed in an upper portion of a reactor to be coupled to the reactor and fixing a pipe;
- the pipe inserted into a hole formed in the fixing part, protruding downward from the fixing part, and having a length adjustable in a vertical direction;
- a spray nozzle provided at a lower end of the pipe;
- and
- a screener provided on a lower side surface of the pipe.
A reactor cleaning method comprising:
- inserting a partial region of each of a plurality of fixing parts of a reactor cleaning apparatus into each of a plurality of holes formed along a circumference of an upper portion of a reactor to couple the reactor and the reactor cleaning apparatus to each other;
- spraying a solvent toward a contaminant accumulated on an inner wall of the reactor using a spray nozzle provided at a lower end of a pipe inserted into a hole formed in the fixing part of the reactor cleaning apparatus;
- dislodging the contaminant accumulated on the inner wall of the reactor using a screener provided on a lower side surface of the pipe while vertically moving the pipe from an upper portion to a lower portion of the reactor by adjusting a length of the pipe of the reactor cleaning apparatus;
- and
- removing the dislodged contaminant from the reactor.
