Embodiment Construction

[0009] Two sets of regenerators (group A and group B) are arranged at the bottom of the walls at both ends of the reduction furnace, and the interior is filled with a new type of regenerator—ceramic honeycomb or ceramic pellets. During normal operation, the regenerators of group A release heat and heat the air flowing through the regenerators of group A; at this time, the regenerators of group B absorb heat and recover the sensible heat of the flue gas flowing through the regenerators of group B. After a reversing cycle, the regenerators of group A absorb heat and the regenerators of group B release heat. In this way, the two regenerators can alternately switch working states to recover the waste heat in the high-temperature flue gas. 2-40 burners are arranged symmetrically on the walls at both ends of the reduction furnace. During normal operation, the fuel is supplied from the burner on one side, and the flue gas is discharged from the burner on the other side, and the direc...

Abstract

A metal Mg reduction furnace of heat accumulating type consisting of firepot, furnace top and bottom, furnace end wall , nozzle , reduction tank and fan features setting end wall inner channel , A set and B set of heat accumulating chambers in which packed fully with new type of accumulation body of ceramic cellular body or ceramic pellet , setting interlocking control valve and switching over valve on external of furnace . The operation state of two said chambers can be switched over alternatively to recover waste heat from high temperature smoke.

Description

technical field [0001] The invention belongs to the nonferrous metallurgy industry, and in particular relates to a novel high-efficiency regenerative type metal magnesium reduction furnace. Background technique [0002] Traditional metal magnesium reduction furnaces generally adopt the structure of single-layer (or double-layer) reduction tanks heated by back flame. However, the flame and flue gas of this traditional structure enter the furnace through the fire-retaining wall, flow through the reduction tank from top to bottom, and quickly exit the furnace through the fire hole. Serious waste of heat. In addition, traditional metal magnesium reduction furnaces generally use raw coal as fuel, which has low combustion efficiency and serious pollution. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of traditional metal magnesium reduction furnaces, such as serious heat waste, low combustion efficiency and serious poll...
