Abstract
The invention discloses a water jacket ascension pipe heat exchanger with a heat insulation and storage layer and a transformation method of the water jacket ascension pipe heat exchanger. The water jacket ascension pipe heat exchanger with the heat insulation and storage layer comprises an ascension pipe heat exchanger body, and the heat insulation and storage layer is attached to the inner wall of the ascension pipe heat exchanger. The transformation method of the ascension pipe heat exchanger comprises the steps of polishing the inner wall of the ascension pipe heat exchanger, welding a fixing piece, pressing the ascension pipe heat exchanger, pouring the heat insulation and storage layer, and drying or air-drying and maintaining the heat insulation and storage layer. The problem that the inner wall of an original ascension pipe heat exchanger is coked is solved, meanwhile, the wall temperature change of the inner wall of the original ascension pipe heat exchanger is reduced, high-temperature oxidation and high-temperature creep of a pipe body metal material are reduced, and the service life of the original ascension pipe heat exchanger is prolonged by 3-5 years.
