Title:
COAL TO ACETYLENE PLASMA REACTOR HAVING COKING INHIBITION AND ONLINE DECOKING FUNCTIONS
Document Type and Number:
WIPO Patent Application WO/2021/093470
Kind Code:
A1
Abstract:
Disclosed is a coal to acetylene plasma reactor having coking inhibition and online decoking functions, comprising a cathode rod which is vertically provided, an anode, and a circulating cooling water sleeve provided at the outer side of the anode. The anode comprises from top to bottom an anode of an electric arc operation section used for matching the cathode rod to generate an electric arc, and an anode of a reaction section located below the electric arc. The anode is grounded. The inner diameter of the anode of the reaction section is 1.2-10 times of that of the anode of the electric arc operation section. Decoking nozzles which can spray decoking media toward the anode of the reaction section are circumferentially provided at the position where the anode of the reaction section is connected to the anode of the electric arc operation section. According to the present invention, a method for changing the inner diameter of the reactor and providing the nozzles for diaphragm protection is used to fundamentally inhibit or even eliminate the decoking phenomenon during the reactor operation, the decoking period does not need to be set, and the continuous cracking operation of the reactor is achieved.
