Waste heat recycling chamber for recycling waste heat of fused magnesium melting lump

Abstract

The invention relates to a waste heat recycling chamber for recycling waste heat of fused magnesium melting lump. The waste heat recycling chamber comprises an annular waste heat recycling chamber anda heat storage container, wherein the annular waste heat recycling chamber is a closed annular space defined by a top water cooling wall, an inner annular water cooling wall and an outer annular water cooling wall jointly; the annular space is a moving cooling channel of the fused magnesium melting lump; a waste heat recycling chamber inlet and a waste heat recycling chamber outlet are formed inthe side face of the annular space, are adjacent to each other and are sealed through an inlet door and an outlet door separately; and the heat storage container is arranged above the annular waste heat recycling chamber and is connected with all water cooling walls of the annular waste heat recycling chamber through an ascending pipe and a descending pipe. Compared with a traditional tunnel typewaste heat recycling device, the waste heat recycling chamber has the advantages of being high in waste heat recycling efficiency, heating uniform in all heated surfaces, stable in thermal energy output, small in occupied area and energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery of fused magnesium fused lumps, in particular to a waste heat recovery chamber for recovering waste heat of fused magnesium fused lumps. Background technique [0002] In the production process of fused magnesia, magnesium fused lumps will be formed after magnesite smelting. The production process requires that the magnesium fused lump can only be cooled naturally, not forced cooling, so as not to affect the crystallization effect of magnesia; at the same time, the magnesium fused lump contains huge waste heat resources that can be recycled. [0003] At present, domestic waste heat recovery devices generally use tunnel-type waste heat recovery boilers. The hot magnesium fused lumps move longitudinally in the tunnel, and the outer wall of the tunnel is the heat-absorbing tube bundle. As time goes by, the magnesium fused lumps are gradually cooled, and the heat emitted Recovered by waste...

AI Technical Summary

Problems solved by technology

Compared with the natural cooling process without waste heat recovery, the cooling temperature difference is smaller, the cooling time is longer, the production efficiency is lower, and the consumption of metal materials is large

At the same time, it will also cause the flow of steam and water in the waste heat recovery device to be poor, and the circulation rate will drop too fast, so that the heating surface at the rear will not be able to produce steam, which will affect the waste heat recovery effect of the entire waste heat recovery device.
