Heat pipe heat exchange device for waste heat recovery, and working method thereof

Abstract

The invention discloses a heat pipe heat exchange device for waste heat recovery, and a working method thereof. The heat exchange device comprises a hot air duct, and the hot air duct is fixedly installed on and communicates with a heat exchanger evaporation shell; the heat exchanger evaporation shell is fixedly provided with and communicates with an air outlet pipe, and an evaporation pipe is fixedly installed in the heat exchanger evaporation shell; the inner top end of the heat exchanger evaporation shell is fixedly provided with a plurality of acoustic soot blowers, and the middle part ofthe top end of the heat exchanger evaporation shell is fixedly connected with an air compression soot blower; the upper end of the evaporation pipe is fixedly provided with and communicates with a steam riser, and the other end of the steam riser is fixedly installed on and communicates with the top end of a heat exchanger condensation shell; a condensation pipe is fixedly installed in the heat exchanger condensation shell, and the other end of the steam riser penetrates through the heat exchanger condensation shell, and communicates with the top end of the condensation pipe; and the bottom end of the condensation pipe is fixedly provided with and communicates with a return pipe. The heat exchange device is scientific and reasonable and environmentally friendly, has the good effects of waste heat absorption and utilization, and is, and is suitable for promotion and application.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a heat pipe heat exchange device for waste heat recovery. Background technique [0002] The recovery and utilization of energy is a subject that people have been studying. Thermal energy is an energy that must be used in industrial production and coal-fired power plants. However, in the process of using thermal energy, it cannot be used for industrial production and coal-fired power plants. The utilization of hot steam, hot flue gas and hot exhaust gas leads to the phenomenon of waste of heat energy in the process of using heat energy. The heat transfer efficiency of the high-temperature gas discharged after combustion is not good, and the heat is difficult to be recycled reasonably. Especially for the exhaust gas temperature of the air preheater in coal-fired power plants, in order to improve the boiler efficiency, the exhaust gas temperature is often reduced as much as possible, but t...
