Description
Technical field
The present invention relates to a kind of melting furnace, specifically, relate to a kind of efficient melting furnace.
Background technology
When making metal casting at present, need raw metal be placed on and carry out heat fused in the melting furnace, pour into a mould then, through mould molding.Raw metal heat fused process need temperature is very high, therefore, need constantly heat raw metal, and the fuel that heating is now used is coal or gas mostly, and coal combustion internal heat gas is to produce the great amount of high-temperature flue gas; And traditional processing method to these high-temperature flue gas is exactly to be discharged into after the cooling processing in the atmosphere, and this way makes high-temperature flue gas in discharging, take away great amount of heat, if can the heat recovery and utilization in the flue gas just can be practiced thrift many fuel.
Summary of the invention
The purpose of this invention is to provide a kind of can be to the flue gas waste heat recovery melting furnace of heat recovery and utilization in the high-temperature flue gas.
The technical scheme that the present invention adopts is:
A kind of efficient melting furnace comprises housing, places melting chamber and combustion chamber in the housing, and said melting chamber is airtight tubular structure; Said melting chamber top sidewall is provided with observation panel, and the lower end of said melting chamber places in the combustion chamber, and said side wall of combustion chamber is provided with dog-house; The bottom of said combustion chamber is provided with slag-drip opening; All have on the said housing and observation panel, dog-house, the corresponding mouth of slag-drip opening, said inner walls is provided with refractory insulating layer, and this refractory insulating layer closely contacts with the outer wall of combustion chamber; Form the circuitous chamber of flue gas between said refractory insulating layer and melting chamber; Said case top is provided with the chimney that passes refractory insulating layer and be communicated with the circuitous chamber of flue gas, and the top of said combustion chamber is provided with the circuitous pipeline of flue gas, and this pipeline is wrapped on the outer wall of melting chamber; The circuitous pipeline of said flue gas is communicated with the circuitous chamber of flue gas, and the refractory insulating layer of said top of combustion chamber is provided with the ash discharging hole that passes housing.
Further, be connected with air blast on the said combustion chamber.
Form the circuitous chamber of flue gas between type refractory insulating layer that this practicality is new and melting chamber, the circuitous chamber of this flue gas is communicated with the circuitous pipeline of flue gas, and the circuitous pipeline of flue gas is wrapped on the outer wall of melting chamber; Like this; The high-temperature flue gas that produces in the combustion chamber is through the circuitous pipeline of flue gas process constantly on the outer wall of melting chamber, and the flue gas of high temperature plays the effect to melting chamber insulation, heating with the heat transferred melting chamber simultaneously; Can improve the melting rate of metal principle in the melting chamber; Then, high-temperature flue gas can continue the effect of bringing extra power into play after coming out to enter in the circuitous chamber of flue gas from flue gas pass-over offset road, and the top of melting chamber is heated, is incubated; The present invention also is provided with the chimney that passes refractory insulating layer and be communicated with the circuitous chamber of flue gas in case top; This chimney was brought into play the high-temperature flue gas of effect the most at last and was discharged; Even, on the refractory insulating layer of top of combustion chamber, be provided with the ash discharging hole that passes housing in order to get rid of dust residual in the housing.
Advantage of the present invention is: to heat recovery and utilization in the high-temperature flue gas, and energy savings, the utilization rate that improves fuel and the burn-off rate of raw metal.
