The invention discloses a cold guide cylinder for rapid cooling of a coal-fired boiler, and relates to the field of boiler cooling and refrigeration. A liquid CO2 storage and output pipeline is connected outside a combustion chamber of the coal-fired boiler, and the output pipeline is provided with a throttle valve and is connected with a cold coil pipe in the combustion chamber. The cold coil pipe is positioned in the cold guide cylinder, and the output tail end of the cold coil pipe is connected into an external gas collecting pipe and finally led into a CO2 collecting device. By means of the cold guide cylinder device, rapid cooling in the boiler is achieved, and the problems of potential safety hazards and equipment damage caused by too high steam temperature are solved.
Description
technical field [0001] The invention discloses a cooling tube used for rapid cooling of a coal-fired boiler, relates to the fields of safety protection and cooling of a coal-fired boiler, and in particular relates to a novel refrigeration system using liquid carbon dioxide as a working medium. Background technique [0002] Liquid carbon dioxide refers to the liquefaction of carbon dioxide gas into a liquid form under high pressure and low temperature. Liquid carbon dioxide is a refrigerant that can be used to preserve food and can also be used for artificial rainfall. It is also an industrial raw material, which can be used to make soda ash, urea and soda. CO2 has a critical pressure: 7.39 MPa and a critical temperature: 31.06°C. When neither the temperature nor the pressure exceeds the critical point, CO2 can be liquefied by increasing the pressure or lowering the temperature. When the pressure or temperature exceeds the critical value, CO2 in this state is called superc...
