Abstract
A closed energy-concentrated multifunctional nonferrous metal smelting furnace relates to the metal ore refining and smelting technical field The smelting furnace is characterized in that a downward sloping combustion wall is wound from the top of the smelting furnace, and is communicated with a recycling pool; the inside of the combustion wall has a hot blast pipe which is connected with a porous melting zone on the bottom of the furnace and an air inlet pipe outside the furnace; the middle part of the furnace is surrounded by a hot air bag; a pair of warming electrodes facing the center are inserted in both sides of the bottom of the furnace; a bottom side of the recycling pool is provided with a hole; the recycling pool is communicated with the bottom of a cleaning pool through a pipe, and extracts and recycles clean coal gas from an outlet on the top of the cleaning pool; and the smelting furnace also has a cracked water combustion chamber. The closed energy-concentrated multifunctional nonferrous metal smelting furnace reduces heat energy radiation, and ensures even and complete smelting without causing caking; the smelting furnace makes use of the heat of rising waste gas inside the furnace so as to reduce energy consumption; the warming electrodes speed up the melting of metal; the low-boiling point metal recycling pool ensures better smelting benefits; the electricity consumption of the smelting furnace is only one twenty second of that of a common smelting furnace; aluminum smelting speed is greatly increased; and the smelting furnace overcomes the disadvantages that the prior refining is not complete, and slag still containing metal is discarded everywhere, thereby wasting resources and polluting the environment.
Description
Technical field
The utility model relates to refinement, the technical field of smelting of metallic ore; Closed cumulative multifunctional smelting furnace for non-ferrous metal specifically.
Background technology
In the refinement of domestic metallic ore, usually the scattering in vain of the refining unnecessary heat energy that gets off of ore is fallen, caused energy consumption big, the cost height; And will not refine clean slag and huddle everywhere, not only contaminated environment, and serious waste resource as rubbish.
Summary of the invention
It is a kind of the unnecessary heat energy recycle of getting off of refining ore that the utility model provides, thereby cut down the consumption of energy, and can not refine once more refining clean slag on furnace design, reaches a kind of closed cumulative multifunctional smelting furnace for non-ferrous metal that makes full use of resource.
The technical scheme that the utility model is taked:
The smelting furnace segmentation connects, center on combustion wall in eel-like figure bottle formula smelting furnace top downward, communicate with low boiling metal recovery pond, the nearly bottom of smelting furnace has porous fusion zone and blast pipe to join, be with high temperature resistant furnace lining around the smelting furnace lower curtate inwall, there is cooling atomizing cover the outer ring, smelting furnace has the hot blast courage to center on around the middle part, smelting furnace roof central authorities has a charging hopper and the outer feed pipe of smelting furnace to join, both sides are inserted with a pair of electrode that heats at the bottom of the smelting furnace towards the center, smelt furnace wall outer bottom end and airduct is arranged to the top, the porous fusion zone joins in bottom and the smelting furnace, and the top joins with the combustion chamber heat airduct that leads to low boiling metal recovery pond, and free wheel is arranged at the bottom of the smelting furnace, place on the movable table base, the base in low boiling metal recovery pond punches; Low boiling metal recovery pond is gone into by the exhausting motor at the bottom of the kitchen sink of environmental purification tower by logical outer pipe, and draws clean coal-gas recovering from the outlet on kitchen sink top; The heavy metal tap hole is arranged at the bottom of the smelting furnace, and the other perforate of furnace bottom side, there is refractory material to surround passage mutually, link to each other with metal recovery cell, the cracking water combustion chamber that constitutes is enclosed mutually by the hot blast courage in the metal recovery cell top, cracking water top of combustion chamber has pipe and porous fusion zone to join, and the metal recovery cell bottom side has molten iron tank, aluminium tank respectively, draws collection mouth separately.
Good effect behind enforcement the utility model is:
Because double-decker is adopted in the furnace wall, has reduced the heat energy radiation; Adopting the porous fusion zone of the little tuyere structure of many rows, make melting evenly, fully, does not lump in inside; In the stove rising waste-gas heat to air heat in the warm-air pipe after, return furnace bottom porous fusion zone by airduct again, improved calory burning; And with cracking water combustion chamber, high temperature sulphur, the hydrogen that produces in the stove is recovered to the porous fusion zone, participates in burning once more; And heat electrode and can quicken metal molten; Be provided with low boiling metal recovery pond in addition, make the smelting benefit better.
Because above measure, conventional way is produced one ton of fine aluminium and is wanted power consumption 12000KW-13000KW; The utility model only needs power consumption 550kw-600KW, power consumption only conventional power consumption 1/22nd; And aluminium metallurgy speed greatly improves: the conventional electrolysis stove can refine 2.2 tons of electrolytic aluminiums, power consumption 22000KW in one day approximately; The utility model per hour can refine the 1.5-2 ton, power consumption 600KW.
The coal gas that produces in stove, the past is excessive in vain have been wasted as waste gas, has reclaimed coal gas in the purifying column by entering in the stove now, the coal gas that produces can be used for the residential area.Can supply about 50,000 families after the discarded coal-gas recovering of a smelting furnace and occupy domestic gas; calculate with 5 kilograms of coals of coal with one day one family, the north; 1 year one family has 50,000 families to calculate with 1825 kilograms in coal with the small town, and button removes the smelting furnace coal; use for the resident with discarded coal-gas recovering; replace the resident and burn coal, can save 340,000 tons of coals in 1 year, and change the contaminated environment of soot all over the sky; save the energy, protected environment.
And conventional way is smelted, and it is not thorough to extract metal, and also metallic slag can all over the mountainly be abandoned everywhere, waste resource, contaminated environment; The utility model just adopts gangue, discarded bauxite, power plant slag to refine as raw material, has saved resource, has safeguarded environment.
