Method for saving activated carbon and porcelain ring in lower head of converter in calcium carbide method polyvinyl chloride production

Abstract

The application discloses a method for saving activated carbon and porcelain rings in a lower head of a converter in production of calcium carbide method polyvinyl chloride, and belongs to the technical field of polyvinyl chloride production, and comprises the following steps: S1, horizontally welding a support frame in a straight cylinder section of the lower head of the converter; S2, laying a steel grating on the support frame, laying a steel wire mesh on the steel grating, and fixing the steel wire mesh to the steel grating by iron wires; the support frame is horizontally welded in the straight cylinder section of the lower head of the converter, the steel grating is laid on the support frame, the steel wire mesh is laid on the steel grating, and the steel wire mesh is fixed to the steel grating by the iron wires; the glass silk cloth I is laid on the steel wire mesh through edge pressing, the lower head gasket is placed on the pressing surface of the lower head, the activated carbon is laid on the glass silk cloth I, the glass silk cloth II is laid on the activated carbon, the filling of the phi 50 porcelain ring and the phi 25 porcelain ring is cancelled, the filling amount of the activated carbon in the lower head of each converter is effectively reduced, the filling weight of the lower head of the converter is reduced, and the lifting and installation risk of the lower head of the converter is reduced.
