AI Technical Summary

Technical Problem

In the existing calcium carbide smelting technology, the radiant heat poured by the calcium carbide smelting furnace is mainly emitted into the environment through natural cooling, resulting in energy waste and increased production costs.

Method used

A radiant heat recovery and utilization system for casting of calcium carbide furnaces is designed, and the radiant heat in the caddyron is absorbed by using an inert gaseous heat exchange medium through the radiant heat exchange mode tunnel kiln, and energy conversion and reuse are realized through the heat exchange device. At the same time, external oxygen is prevented from entering through the calcium carbide protection device to avoid oxidation of calcium carbide.

Benefits of technology

It realizes efficient recycling and utilization of radiant heat from casting of calcium carbide smelting furnaces, reduces energy waste, reduces production costs, and improves the production quality of calcium carbide.

Abstract

A calcium carbide furnace pouring radiant heat recycling system comprises a calcium carbide pouring radiant heat exchange fixed die tunnel kiln, an inert gaseous heat exchange medium supply device, a calcium carbide protection device and a heat exchange device, and a fixed die trolley poured with calcium carbide is placed in the calcium carbide pouring radiant heat exchange fixed die tunnel kiln; an inert gaseous heat exchange medium is prepared by an inert gaseous heat exchange medium supply device and is continuously conveyed into a calcium carbide pouring radiant heat exchange fixed die tunnel kiln at a preset first pressure; the inert gaseous heat exchange medium entering the calcium carbide pouring radiant heat exchange fixed die tunnel kiln is used for absorbing radiant heat of calcium carbide on the fixed die trolley, so that the inert gaseous heat exchange medium becomes a high-temperature inert gaseous heat exchange medium, and the high-temperature inert gaseous heat exchange medium enters the heat exchange device from an exhaust port of the calcium carbide pouring radiant heat exchange fixed die tunnel kiln. The heat exchange device conducts heat exchange on the entered high-temperature inert gaseous heat exchange medium so as to achieve energy conversion.
