Description
Technical field
The present invention relates to a kind of furnace cupola, and in particular to a kind of energy saving and environment friendly totally-enclosed blast-heating cupola.
Background technology
Blast-heating cupola is for melting used in molten iron foundry machinery part, mainly by body of heater, forehearth and heating system group
Into.Forehearth is provided with tapping hole, slag notch, is connected by passing a bridge with body of heater.Body of heater is divided into furnace roof, shaft and cupola well, because of furnace roof
It is provided with upward outlet therefore claims furnace cupola.The furnace roof of existing blast-heating cupola uses evolution formula, although being connected with dust pelletizing system,
But still there are a large amount of dusts to discharge on furnace roof, while large quantity of exhaust gas waste heat can be also dispersed into air, cause hot loss of energy；
Heat exchange is swapped using hot air container, therefore hot air container contacts thermal-flame and is easy to burn out deformation often, typically continuously makes
It is no more than half a year with the life-span, and the manufacture cost of repairs is larger, improves the production cost of cast iron.
The content of the invention
The present invention solves the deficiencies in the prior art, there is provided heat energy can be made full use of and can to reduce and is produced into by one kind
This energy saving and environment friendly totally-enclosed blast-heating cupola.
The used to achieve these goals technical scheme of the present invention is：
A kind of energy saving and environment friendly totally-enclosed blast-heating cupola, including body of heater, the bottom of furnace body at the top of bellows with being connected, in body of heater
Outside, which is provided with, makes body of heater shell be in double-deck and top closure totally-enclosed housing, is provided between case inside and the body of heater outside
Ajutage, the ajutage import is located at case top side, and is connected with air blower, and ajutage exports and is located at bottom of furnace body
The connection of bellows air inlet, the housing and body of heater charge door corresponding position be provided with charge door, housing bottom provided with and dedusting wind
The dust excluding hood of machine connection.Hot useless furnace gas is collected discharge by the present invention using totally-enclosed mode, in discharge process with air-supply
Pipe carries out abundant heat transfer, and the natural wind for burner hearth of making a gift to someone is become into hot blast using EGT, has both reduced thermal losses and has improved iron
Coke ratio is easy to focus on waste gas again, realizes the purpose of energy-saving safety and environmental protection.
Further, the ajutage by ajutage import to ajutage export between in it is tortuous be distributed in case inside with
Between on the outside of body of heater, by the ajutage of tortuous distribution, ajutage is set fully to be contacted with high exhaust temperatures, there is provided in high ajutage
Wind-warm syndrome, increase iron(-)coke ratio.
Preferably, the ajutage is stainless steel tube.
Further, the case top opposite side is additionally provided with the automatic burst-preventing valve that furnace gas superpressure can automatically open up.This hair
Bright that automatic burst-preventing valve is stayed at the top of the body of heater of closing, furnace gas superpressure can automatically open up, it is ensured that safety.
Further, it is connected at the top of the dust excluding hood with housing bottom, any side in bottom is provided with dust removal port, and the dust removal port is led to
Dedusting fan is crossed to be connected with dust pelletizing system.Waste gas will be connected by the present invention by dedusting fan with dust pelletizing system, enter one to waste gas
Discharged again after step processing, reduce environmental pollution.
Present invention eliminates hot air container, and body of heater shell is made into bilayer and closes chimney, distributing disc between double casing
Bent stainless steel tube, hot useless furnace gas can not only be collected to discharge, while carry out fully heat with ajutage in discharge process
Transmit, the natural wind that burner hearth is will be fed into using EGT becomes hot blast, has not only reduced thermal losses and has improved iron(-)coke ratio but also be easy to collect
Middle processing waste gas, realize the purpose of energy-saving safety and environmental protection；Automatic burst-preventing valve is stayed at the top of the body of heater of inventive closure, furnace gas surpasses
Pressure can automatically open up, it is ensured that safety.
Brief description of the drawings
