AI Technical Summary

Technical Problem

The waste heat recovery device in the existing quenching pool fails to effectively recover the heat from the hot slag dropped by the workpiece, causing the heat to dissipate into the cooling water and air, causing energy waste.

Method used

A heat recovery system for a quenching tank is designed, including a heat recovery device and a fluid drive assembly installed in the quenching tank. The heat recovery device consists of a hot slag storage compartment, a circulation channel and a heat exchange channel. The fluid drive assembly drives the coolant flow through the nozzle and introduces the hot slag to the input end of the heat recovery device.

Benefits of technology

The collection of hot slag and the concentrated recovery of heat in the coolant and hot slag are achieved, the heat recovery efficiency is improved, and the heat dissipation and energy waste are avoided.

Abstract

The invention is applicable to the field of quenching baths, and provides a heat recovery system of a quenching bath, which comprises a heat recoverer and a fluid driving assembly mounted in the quenching bath, the heat recoverer comprises a hot slag storage bin arranged at the input end of the heat recoverer, a circulation channel with the end corresponding to the hot slag storage bin and allowing cooling liquid to pass through and a heat exchange channel distributed in the side wall of the circulation channel, a heat absorption medium flows in the heat exchange channel, and the heat exchange channel is connected with an external heat absorption medium circulation device through a pipeline. One side wall of the hot slag storage bin is of an opening and closing structure, and when the fluid driving assembly works, the opening and closing structure is in an open state so that hot slag can enter the hot slag storage bin; when the fluid driving assembly stops working, the opening and closing structure is in a closed state; and at least one side wall of the hot slag storage bin is provided with a circulating hole through which the cooling liquid passes, so that the hot slag can be collected, heat in the cooling liquid and the hot slag can be recycled in a centralized manner, and the heat recycling efficiency is high.
