Description
Technical field
The utility model belongs to a kind of magnesium metal smelting device of nonferrous metallurgy industry, particularly a kind of new and effective direct combustion, the close reduction furnace for smelting metal magnesium putting formula.
Background technology
Traditional reduction furnace for smelting metal magnesium generally all adopts the structure of reverberatory heating individual layer (bilayer) reductive jar.But the flame of this traditional structure and flue gas climb over firebreak and enter burner hearth, flow through reductive jar from top to bottom, and very fast by crossing fire hole discharge burner hearth, and heat-transfer effect is poor, and in addition, reductive jar arrangement is not compact, and heat utilization efficiency is low.
Utility model content
The purpose of this utility model is to solve the problem, a kind of two-sided double high-density Mg-smelting furnace is proposed, this two-sided double high-density Mg-smelting furnace make use of the heat of fuel release to a greater extent, shorten the recovery time, improve single stove productivity, reduce production cost, recycle fume afterheat, save fuel, be priorly reduction of igniting difficulty, made fire box temperature more even.
The purpose of this utility model is achieved through the following technical solutions: two-sided double high-density Mg-smelting furnace, be provided with body of heater, it is characterized in that: described body of heater is provided with furnace roof, the both sides body of heater of correspondence is set to body of heater headwall by described body of heater, described body of heater headwall bottom is provided with a burner open holes, described burner passes through burner open holes to flame in body of heater, described body of heater headwall is added is provided with supporting steel pipe, described supporting steel pipe is welded with high temperature steel pad, described high temperature steel pad is added is provided with reductive jar, described body of heater headwall is provided with smoke outlet at top, described furnace bottom is provided with two slide rails, described two slide rails are equipped with ash discharge dolly, described ash discharge dolly lays insulation material layer and refractory masses.
Described reductive jar adopts high-density arrangement, i.e. four layers of upper and lower wrong row's mode of tank, and lower two-layer reductive jar is towards a side opening of stove, and upper two-layer reductive jar is towards opposite side opening.
Described body of heater both sides arrange two not contour service platforms, make both sides facilitate input and output material, and meet original operating habit.
Described supporting steel pipe uses water-cooled steel pipe, often props up an all corresponding water-cooled steel pipe bottom reductive jar, steel pipe upper surface weldering high temperature steel pad, Guan Yugang pad external welding anchoring piece pouring heat insulating refractory masses, logical recirculated cooling water guarantee steel strength in pipe.
Described body of heater headwall combined water-cooled steel pipe support, steel pipe external welding anchoring piece also lays mould material rear support stove headwall.
Described body of heater headwall has 3 exhanst gas outlets, arrange flue gas-air heat exchanger in flue, described interchanger uses tubular heat exchanger, makes with high temperature steel.
The utility model burner arrangement is bottom reduction furnace on headwall, and entirety have employed the combustion system of direct-fired naked burning reductive jar, the flame of the fuel combustion that two burners spray forms swirling flow again in burner hearth, heat exchange in efficient hardening stove; The ashes that fuel combustion produces drop on interval on furnace bottom dolly and release, and achieve mechanical ash discharge; Reductive jar adopts the high-density arrangement of about four layers wrong rows, make use of the heat of fuel release efficiently, upper two-layer and both direction that lower two-layer tank mouth is towards the opposite, arrange two not contour service platforms, vacuum system corresponding with it also leads to two contrary directions; The support of reductive jar and body of heater headwall employs the steel pipe of the heat insulation resistance to material of interior logical recirculated cooling water external application, and the recirculated cooling water in pipe forms self-circulation system; Arrange the flue gas-air heat exchanger that high temperature steel is made in flue, reclaim the waste heat of high-temperature flue gas, reduce igniting difficulty, improve the homogeneity in in-furnace temperature and temperature field, further increase energy-saving effect.
