1. 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 control part including a knob that vertically adjust the length of the pipe;
a spray nozzle provided at a lower end of the pipe; and
a scraper provided on a lower side surface of the pipe,
wherein the scraper is formed of a metal material,
wherein the scraper is provided at a position higher than the lower end of the pipe at which the spray nozzle is formed,
wherein the pipe is a winding-up type pipe having multiple-stage pipes overlapped in a layer form and is configured to move only vertically,
wherein the reactor is an ethylene oligomerization reactor selected from the group consisting of a continuous stirred-tank reactor, a plug flow reactor, and a bubble column reactor,
wherein the scraper protrudes toward an inner wall of the reactor from the pipe,
wherein an outer peripheral surface of a region of the scraper protruding toward the inner wall of the reactor has a curve corresponding to a curve of the inner wall of the reactor,
wherein the scraper is configured to dislodge a contaminant accumulated on the inner wall of the reactor by the region of the scraper when the length of the pipe is adjusted by the control part to move the scraper vertically from an upper portion to a lower portion of the reactor, and
wherein the spray nozzle is directed to spray a solvent toward the inner wall of the reactor.
