Abstract

The invention discloses a high-temperature flue gas heat energy recovery system. The high-temperature flue gas heat energy recovery system comprises a gas inlet pipe and a gas outlet pipe, one end of the gas outlet pipe is fixedly connected with a position between the two ends of the gas inlet pipe, the gas outlet pipe communicates with the gas inlet pipe, a first partition plate is fixedly connected to the interior of the gas inlet pipe, the first partition plate is fixedly connected with a first heat exchange pipe, and the first heat exchange pipe is arranged in a snakelike mode along the central axis of the air inlet pipe. A cold medium is input into an inlet of the first heat exchange pipe, a hot medium is output from an outlet of the first heat exchange pipe, the cold medium becomes a hot medium after absorbing heat and is discharged from the outlet of the first heat exchange pipe, the outlet of the first heat exchange pipe is connected with a cleaning pool, water in the cleaning pool circularly flows through the first heat exchange pipe and absorbs the heat of high-temperature flue gas, recovery is carried out on the heat energy in the high-temperature flue gas, after the water in the cleaning pool is heated, sundries and oil stains adhered to the surface of a workpiece can be separated from the workpiece more quickly, and therefore the cleaning effect and the cleaning efficiency are improved.

Description

technical field [0001] The present application relates to the technical field of heat recovery, in particular to a high-temperature flue gas heat energy recovery system. Background technique [0002] In the manufacturing process of fasteners such as bolts and nuts, quenching and annealing processes are required. In order to improve the efficiency of quenching and annealing, it is usually used to pass through the quenching furnace and annealing furnace. The quenching furnace is equipped with a heater and a quenching liquid. (water or oil), put the workpiece on the conveyor belt, when the workpiece passes through the quenching furnace with the conveyor belt, it is heated first, and then enters to complete quenching, and after quenching, it goes through the annealing furnace with the conveyor belt to complete annealing. [0003] After the workpiece enters the quenching furnace, the workpiece is in contact with the air in the quenching furnace and a part of the heat is transferr...
