The operation state of two said chambers can be switched over alternatively to recover waste heat from high temperature smoke.
Description
Technical field
The invention belongs to the nonferrous metallurgy industry, especially relate to a kind of new and effective heat accumulating type metal magnesium reduction furnace.
Background technology
Traditional metal magnesium reduction furnace generally all adopts the structure of reverberatory heating individual layer (or double-deck) reduction jar.But the flame of this traditional structure and flue gas climb over firebreak and enter burner hearth, the reduction jar of flowing through from top to bottom, and discharge burner hearth very soon by crossing fire hole, funnel temperature up to 1200 ℃ about, can not recycle preferably, heat waste is serious.In addition, the conventional metals magnesium reducing furnace generally acts as a fuel with raw coal, and efficiency of combustion is low, and is seriously polluted.
Summary of the invention
The objective of the invention is to overcome that the heat waste of conventional metals magnesium reducing furnace is serious, efficiency of combustion is low, with serious pollution shortcoming, the new and effective magnesium reducing furnace that a kind of thermal field is even, energy consumption is low, production efficiency is high is provided.
A kind of heat accumulating type metal magnesium reduction furnace, reduction furnace is made of burner hearth 1, furnace roof 2, stove headwall 3, burner 5, reduction jars 9, furnace bottom 10, blower fan 12, it is characterized in that being provided with in the stove headwall interior passageway 4, A group regenerator 7, B group regenerator 8, regenerator inside and is full of novel heat storage---ceramic honeycomb body or ceramic bead.Stove is provided with chain control valve 6, switching valve 11 outward.Furnace roof 2, stove headwall 3, furnace bottom 10 are built by laying bricks or stones by refractory materials and are formed, headwall interior passageway 4 is cavitys of stove headwall inside, A group regenerator 7 and B group regenerator 8 are positioned at the bottom of headwall interior passageway 4, burner 5 passes stove headwall 3 and stretches into burner hearth 1, chain control valve 6 is the folding degree of control burner 5 automatically, the tank body of reduction jar 9 places in the burner hearth 1, and switching valve 11 is connected with passage or steel pipe that A group regenerator 7, B group regenerator 8, blower fan 12 are built by laying bricks or stones by refractory materials.
Structure of the present invention and handling characteristics are as follows: (1) arranges two groups of regenerator (A group and B group) in reduction furnace two headwalls bottom, inside is full of novel heat storage---ceramic honeycomb body or ceramic bead.During normal the operation, the air that the A that flows through organizes heat storage is heated in the heat release of A group regenerator; At this moment, the sensible heat that the B that flows through organizes the flue gas of heat storage is reclaimed in the heat absorption of B group regenerator.After a commutation cycle, the heat absorption of A group heat storage, the heat release of B group heat storage, like this, two regenerator can replace the switch operating state and reclaim waste heat in the high-temperature flue gas.(2) a symmetric arrangement 2-40 burner on two headwalls of reduction furnace.During normal the operation, fuel is infeeded by the burner of a side, and flue gas is discharged from the burner of opposite side, periodically commutation.(3) two ends of reduction furnace within the walls portion arranged gas (high temperature air or flue gas) passage.Enter regenerator through crossing the gas passage after high-temperature flue gas in the burner hearth is discharged by burner, the air in the regenerator after the preheating also is to cross the gas passage through this to enter burner hearth by burner more combustion-supporting.(4) fuel uses coke-oven gas or producer gas.Adopt not only efficiency of combustion height of clean fuel, and the problem of environmental pollution in traditional magnesium reducing furnace production process is improved at all, the more important thing is that the flue gas flow that produced can not cause the obstruction of heat storage through heat storage, helps to prolong the life-span of heat storage.(5) combustion system is direct-fired, i.e. the furnace gas Direct Contact Heating reduction tank of fuel generation.The combustion system of direct combustion has not only been saved furnace cavity directly in the burner hearth internal-combustion, the more important thing is and has improved heat transfer efficiency.(6) the chain control of switching valve and fuel control valve, and programming control automatically.
The use of this heat accumulating type magnesium reducing furnace, the heat of the high-temperature flue gas (about 1200 ℃) of discharging burner hearth is reclaimed to greatest extent, make the final funnel temperature of reduction furnace reduce to below 200 ℃, the heat utilization efficiency of reduction furnace is brought up to more than 30% by about 8～10% of traditional burner, have good energy-saving effect, can obtain good economic benefits and environmental benefit.
