Title:
HIGH-TEMPERATURE FLUE GAS MOLTEN SALT HEAT EXCHANGER AND HEAT EXCHANGE METHOD
Document Type and Number:
WIPO Patent Application WO/2022/134226
Kind Code:
A1
Abstract:
A high-temperature flue gas molten salt heat exchanger and a heat exchange method. The heat exchanger comprises a controller and a heat exchange chamber. The heat exchange chamber comprises regenerative ceramics (3), an inner wall, a thermal insulation layer (5) and an outer housing. Flue gas channels (6) pass through the heat exchange chamber. The heat exchange chamber is internally provided with a plurality of heating rods (4), and the heat exchange chamber is also internally provided with a plurality of temperature sensors (1) and pressure sensors (2). The temperature sensors (1) and pressure sensors (2) are connected to the controller, and the controller controls the heat exchange chamber to work. When used, the heat exchanger is first preheated to a set temperature. The controller opens the flue gas channels, and the heat exchange chamber is heated to an operating temperature after being blown by incoming air, the flow rate of low-concentration flue gas is adjusted, and the temperature and pressure during the heat exchange process are recorded. The heat exchange method provided for the heat exchanger can strengthen heat exchange, can withstand high-temperature flue gas, and is resistant to molten salt corrosion, and the service life of the heat exchanger under high-temperature conditions is prolonged.
