Abstract
The invention discloses an electrically fused magnesium lump waste heat reclaiming device and method. The device consists of a closed furnace jacket, a heat exchanger and a draught fan; the closed furnace jacket consists of a furnace vehicle bottom plate (1), a furnace shell (6) and a furnace cover (7); the heat exchanger can be a waste heat boiler or a raw material preheating chamber; an air inlet pipeline (2) and a valve (9) are arranged below the furnace vehicle bottom plate, and an upright post (4) and a guide plate (5) are arranged above the furnace vehicle bottom plate; the furnace cover is buckled at the upper port of the furnace shell and connected with the heat exchanger (9) through a pipeline (8); the air outlet of the heat exchanger is connected with the draught fan (14) through a pipeline (13); and the air outlet of the draught fan is connected with the air inlet pipeline (2) of the furnace vehicle bottom plate. Therefore, a closed circulating system is formed, external cold air is prevented from entering, recycle of waste heat is realized, and the device has remarkable energy-saving effect.
Description
Technical field: the present invention relates to a kind of waste-heat recovery device and method, especially a kind of electric-melting magnesium lump afterheat retracting device and method,
Background technology: electric-melting magnesium melting temperature is more than 3000 degree, to stick together to lower the temperature up to more than 1500 electric-melting magnesium of spending to electro-temperature after the melting and cool off tens hours, reach the workman and can carry out broken temperature, in this course, a large amount of waste heats are dispersed into the workshop, have not only caused very big energy waste also to worsen working environment, if can recycle waste heat, to save a large amount of energy, by retrieval and investigation, up to the present also not have relevant technological invention and recovery example.
Summary of the invention: in order to address the above problem, the invention provides a kind of electric-melting magnesium lump afterheat retracting device and method, the waste heat that electric-melting magnesium is sticked together obtains a large amount of recyclings, can also improve working environment, realize that the technical scheme that above-mentioned purpose is taked is characterised in that: by the sealing boiler clothing, heat exchanger and air-introduced machine are formed, the sealing boiler clothing is by stove car bottom plate (1), furnace shell (6), bell (7) is formed, heat exchanger can be that waste heat boiler also can be a dog house, intake stack (2) and valve (9) are arranged below the stove car bottom plate, column (4) and deflector (5) are arranged above, it is suitable for reading and be connected with heat exchanger (9) by pipeline (8) that bell is buckled in furnace shell, the air outlet of heat exchanger is connected with air-introduced machine (14) by pipeline (13), the air outlet of air-introduced machine is connected with the intake stack (2) of stove car bottom plate again, constitute closed cycle system according to this, prevent that cool ambient air from entering, realize the recycling of waste heat, all parts all need be handled through insulation, the invention has the beneficial effects as follows and to recycle waste heat to greatest extent, have obvious energy-saving effect, further specify below in conjunction with drawings and Examples.
Accompanying drawing is retracting device structure and method flow diagram
Embodiment: architectural feature shown in the drawings is: by stove car bottom plate (1), furnace shell (6), bell (7), pipeline (8), heat exchanger (9), pipeline (13), air-introduced machine (14) is formed, intake stack (2) and valve (3) are arranged below the stove car bottom plate (1), column (4) is arranged above, deflector (5) is arranged above the column, if waste heat boiler, safety valve (10) is arranged above, turnover water valve (11,12), method flow is characterised in that: furnace shell (6) is sitting on the stove car bottom plate (1), the inside is that electric-melting magnesium sticks together, buckle bell (7) above, with pipeline (8) exhaust outlet of bell and the air inlet of heat exchanger (9) are connected, the air outlet of heat exchanger is connected with air-introduced machine (14) by pipeline (13), the air outlet of air-introduced machine is connected with the intake stack (2) of stove car bottom plate again, constitute closed cycle system according to this, open valve (3), startup air-introduced machine (14) hot blast just enters into heat exchanger and carries out waste heat recovery, hot blast after the cooling replaces cold air and enters in the furnace shell, recovery circulates, when hot blast temperature approaches boiler temperature, if still have recovery value, can emit hot water, add cold water and proceed to reclaim, till hot blast temperature approaches environment temperature.
