Heat recycling device of smelting furnace

Abstract

The invention relates to the technical field of smelting furnaces, and discloses a heat recycling device of a smelting furnace. The heat recycling device of the smelting furnace comprises a first base, a second base and a third base, wherein a furnace body is fixedly connected to the top part of the first base; a chimney fixedly communicates to the top part of the furnace body; a first fixing ringis fixedly sleeved on the bottom part of an outer surface of the chimney; a heat exchange guide plate located above the first fixing ring is fixedly sleeved on the outer surface of the chimney; and ahot water collection tank is fixedly sleeved on an outer surface of the heat exchange guide plate. According to the heat recycling device of the smelting furnace, the heat exchange guide plate can beused for heating water in the hot water collection tank through collecting heat on the chimney, and water is conveyed to a hot water tank through the pumping of the first pump and is then dischargedfrom a drainage pipe for the use by people, so that the outer wall of the chimney can be cooled, the service life of the chimney is prolonged, meanwhile, an effect on recycling waste heat is achieved,the energy is saved, and the energy utilization ratio is improved.

Description

technical field [0001] The invention relates to the technical field of smelting furnaces, in particular to a heat recovery and utilization device for smelting furnaces. Background technique [0002] Smelting is a refining technology, which refers to the extraction of metals from ores by means of roasting, smelting, electrolysis, and the use of chemicals, to reduce impurities contained in metals or to increase certain components in metals, and to smelt them into required metals. . [0003] When the metal in the ore needs to be extracted, the ore needs to be placed inside the furnace, and the metal in the ore is extracted by the high temperature of the furnace, and then the exhaust gas is discharged from the chimney, but the exhaust gas contains a lot of heat, and the exhaust gas The discharge will cause the chimney to generate heat, which will affect the service life of the chimney. The heat discharge will not be fully utilized and will also cause energy waste. Therefore, we...
