Abstract

The invention discloses a waste heat recycling device for steelmaking, and relates to the technical field of steelmaking waste heat recycling. The waste heat recycling device for steelmaking comprises a gas inlet pipe and a treatment device, the top end of the gas inlet pipe is communicated with the interior of the treatment device, a spiral water guide sheet is fixed to the inner wall of the gas inlet pipe and is made of a heat conduction metal sheet material, and a spiral groove is formed between the spiral water guide sheet and the inner wall of the gas inlet pipe. According to the waste heat recycling device for steelmaking, water can be added into the gas inlet pipe by arranging a water inlet, and the water added into the gas inlet pipe can flow in the spiral groove directly formed by the spiral water guide sheet and the gas inlet pipe and finally flows out through a water outlet; and hot waste gas rising from the bottom of the gas inlet pipe can heat the water flowing on the spiral water guide sheet, so that the water becomes water vapor, the humidity in the gas inlet pipe is improved, and the probability of combustion and explosion of carbon monoxide in the gas inlet pipe is reduced.

Description

technical field [0001] The invention relates to the technical field of steelmaking waste heat recovery, in particular to a steelmaking waste heat recovery and utilization device. Background technique [0002] Steelmaking refers to controlling the carbon content (generally less than 2%), eliminating harmful elements such as P, S, O, and N, retaining or increasing beneficial elements such as Si, Mn, Ni, and Cr, and adjusting the ratio between elements to obtain the best performance. [0003] In the existing steelmaking process, a large amount of waste gas will be generated. These waste gases contain a large amount of carbon monoxide, and the temperature is also high. When the waste gas leaks during the discharge and treatment process, the high content of carbon monoxide may cause carbon monoxide poisoning of nearby personnel. thereby causing danger. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the p...
