Abstract

The invention discloses an integral superheater which comprises a steam collector and a superheater body. Input pipelines and an output pipeline communicate to the steam collector. The superheater body comprises a shell, second-stage heated pieces, a first-stage heated piece and a rotating lifting device. Openings are formed in the two ends of the shell. The second-stage heated pieces and the first-stage heated piece are arranged in the shell and communicate with the outside through the rotating lifting device. The input ends of the second-stage heated piece serve as refrigerant inlets, and the output ends of the second-stage heated pieces communicate with the input pipelines. The input end of the first-stage heated piece communicates with the output pipeline, and the output end of the first-stage heated piece carries out outward output. In a waste heat recovery system, the integral superheater is utilized as a heat exchanger. The work number and the heated area of the heated pieces can be adjusted through the rotating lifting device, maintenance and replacement of heated face parts can be completed in the production process, and safety and stability of the waste heat recovery process are guaranteed. In the metallurgical process, process heat energy can be efficiently recycled, and the problem of environment heat pollution can be solved.

Description

technical field [0001] The invention belongs to the technical field of nonferrous metal smelting, and in particular relates to an integrated superheater. Background technique [0002] There are many medium and high temperature fluids in the field of nonferrous metal smelting technology, such as: medium and high temperature flue gas, high temperature slag, medium and high temperature metal melt, high temperature molten salt, etc. [0003] At present, the non-ferrous metal smelting industry has very limited R&D and application of waste heat recovery of medium and high temperature fluids. At present, the waste heat recovery of high-temperature flue gas is widely used, and it only stops at generating saturated steam, and the electricity generated by sending it to the power generation system is far less than Superheating system; most of the heat of other medium and high temperature fluids is lost in the process of process flow, and there is no recovery measure. [0004] In the p...
