Power station boiler flue gas waste heat utilization equipment and working method thereof

Abstract

The invention discloses power station boiler flue gas waste heat utilization equipment and a working method thereof, and relates to the technical field of boiler flue gas recycling equipment.The equipment comprises a shell, a sealing door, a water tank, a baffle, a mounting plate and a sliding plate; a first opening is formed in the top of the shell, a flange plate is arranged on the side end face of the water tank in the circumferential direction of the water tank, a sealing cover, a water inlet pipe and a water outlet pipe are arranged on the upper end face of the water tank, and the water inlet pipe and the water outlet pipe are communicated with the interior of the water tank. The water tank extends into the shell from the first opening, the end face, facing the shell, of the flange plate tightly presses the shell, two sets of opposite side faces of the water tank tightly press two sets of inner walls of the shell respectively, and a heating bin is defined by the other two sets of opposite side faces of the water tank and the water tank. The equipment is convenient to use, high-temperature flue gas can be efficiently utilized for heating water, and the equipment is convenient to clean.

Description

technical field [0001] The invention relates to the technical field of boiler flue gas recycling equipment, in particular to a power plant boiler flue gas waste heat utilization equipment. Background technique [0002] A boiler is an energy converter that uses the heat energy released by the combustion of fuel to heat water or other fluids to a certain temperature; when the fuel is burned in the boiler, a large amount of flue gas will be generated, and the temperature of these flue gas can reach more than 1000 ℃ , if the high-temperature flue gas is directly discharged, it will cause waste of thermal energy in the flue gas; at this stage, the lack of energy has become a problem that plagues people, so it is necessary to make reasonable use of the thermal energy in the high-temperature flue gas, usually using more high-temperature flue gas. The water is heated to obtain the hot water required for artificial daily use; however, when the existing waste heat utilization equipmen...

Problems solved by technology

[0002] A boiler is a kind of energy converter, which is a device that uses the heat released by fuel combustion to heat water or other fluids to a certain temperature; when fuel is burned in a boiler, a large amount of flue gas will be produced, and the temperature of these flue gases can reach above 1000°C , if the high-temperature flue gas is discharged directly, it will cause waste of heat energy in the flue gas; at this stage, energy shortage has become a problem that plagues people, so it is necessary to make reasonable use of the heat energy in the high-temperature flue gas, and usually use more high-temperature flue gas Heating the water to obtain the hot water required by artificial daily; however, when the existing waste heat utilization equipment uses high-temperature flue gas to heat water, the heat energy utilization efficiency is low during the heat exchange period of the flue gas. It is convenient to clean, and after long-term use, dirt and impurities adhere to the inner wall of the equipment, which greatly reduces the heat exchange efficiency of high-temperature flue gas; therefore, this application proposes a utility boiler flue gas waste heat utilization equipment
