A high-temperature waste heat power generation device for metal smelting waste slag

Abstract

The invention provides a metal smelting waste slag high-temperature waste heat generation device. The metal smelting waste slag high-temperature waste heat generation device comprises a steam structure, a generation device structure, a metal smelting waste slag conveying structure and a metal smelting furnace. A heat conduction plate I is installed at the upper end of a heat-insulation conveying groove. A water containing cavity is formed in the upper end of the heat conduction plate I. A heat-insulation outer shell I is installed at the upper end of the water containing cavity. A heat-insulation outer shell II is installed at the lower end of a steam outlet. A water inlet is assembled on the right side of the steam outlet. A control valve II is arranged on the water inlet. A water flowing opening is installed on the left side of the heat-insulation outer shell II. A waste slag inlet is assembled under the water flowing opening. A water adding cavity is arranged at the right end of the water flowing opening. A heat conduction plate II is installed inside the water adding cavity and internally provided with a waste slag containing cavity. A waste slag outlet is assembled at the lower end of the waste slag containing cavity. A water outlet is installed on the right side of the waste slag outlet. A control valve II is arranged on the water outlet. The metal smelting waste slag high-temperature waste heat generation device improves the waste heat utilization rate, can recycle water resources and relieves labor intensity.

Description

technical field [0001] The invention relates to a high-temperature waste heat power generation device for metal smelting waste residue, which belongs to the field of mechanical equipment. Background technique [0002] In the current metal smelting process, most of them use the technology of converting the excess heat energy on the waste slag generated after metal smelting into electrical energy. Waste heat power generation is not only energy-saving, but also conducive to environmental protection. The important equipment for waste heat power generation is the steam boiler. It uses the excess heat energy on the waste slag produced after metal smelting as a heat source to produce steam for power generation. Because the temperature of the working medium is not high, the boiler is large in size and consumes a lot of metal. In the prior art, the waste slag is transferred from the smelting furnace In the process of reaching the steam boiler, the waste heat on the waste slag will d...

Problems solved by technology

It uses the excess heat energy on the waste slag produced after metal smelting as a heat source to produce steam for power generation. Because the temperature of the working medium is not high, the boiler is large in size and consumes a lot of metal. In the prior art, the waste slag is transferred from the smelting furnace In the process of reaching the steam boiler, the waste heat on the waste slag will dissipate, resulting in a lower utilization rate. The existing steam boilers are equipped with water storage devices inside and waste slag outside. This structure does not have a high utilization rate of waste heat from waste slag.
