Abstract

The invention provides a waste heat recovery device of an aluminum alloy smelting furnace. The waste heat recovery device comprises a tail gas collecting tube and a heat exchange tube, wherein an air inlet of the tail gas collecting tuber is located above an opening of a swirl chamber, the tail gas collecting tube is connected to the outer side of the heat exchange tube in a sleeving manner, one end of the heat exchange tube stretches into the air inlet of the tail gas collecting tube and is located outside the tail gas collecting tube, and the other end of the heat exchange tube is communicated with the furnace body internally; the tail gas collecting tube is provided with a first fan, and the heat exchange tube is provided with a second fan; and a guiding vane is arranged between the inner wall of the tail gas collecting tube and the inner wall of the heat exchange tube, and the guiding vane is arranged spirally around a center axis of the heat exchange tube.

Description

technical field [0001] The present application relates to the technical field of aluminum alloy melting furnaces, in particular to a waste heat recovery device for aluminum alloy melting furnaces. Background technique [0002] The aluminum alloy melting furnace is used to heat and melt aluminum alloy raw materials. The aluminum alloy melting furnace in the prior art includes a furnace body and a vortex chamber. Through the vortex chamber, the vortex chamber is located outside the furnace body, and the opening of the vortex chamber faces upward and is open. When the liquid aluminum is in the vortex chamber, the liquid surface is in contact with the external air, and the aluminum chips are put into the vortex chamber. The liquid aluminum in the vortex chamber makes the aluminum The shavings are melted or the aluminum shavings are brought into the furnace body to be melted again. Due to the high temperature of the liquid aluminum, the liquid aluminum transfers heat to the outs...
