Description
Technical field
The present invention relates to calcining furnace field, especially a kind of high-temperature calcination exhaust-gas treatment furnace.
Background technique
High-temperature calcination stove is a kind of common calciner plant, for being sintered calcining to industrial products.
Existing includes a furnace body shell, gas-guide tube is equipped in furnace body shell, uniform intervals are equipped in the gas-guide tube
Multiple gas nozzles, the gas-guide tube are connected with gas storage case and gasifier section, the furnace by export outside furnace body inner casing
Body case upper end is equipped with escape pipe, and furnace body shell lower end is equipped with air inlet pipe.In calcining, gas-guide tube is stored up combustion gas by combustion gas
Deposit in case and import, industrial products are calcined by gas nozzle ejection after gasifier section is lighted, the exhaust gas of generation by
Escape pipe is expelled to device for recovering tail gas recycling.
Above-mentioned calcining furnace has certain problems, and is the waste that will cause waste gas residual heat first, and heating efficiency is lower；Separately
Outside, after normal temperature air external in calcination process enters furnace body shell by air inlet pipe, due to the High Temperature Gas in furnace body shell
There are the larger temperature difference for body, accordingly, it is possible to will appear sintered products due to hot and cold air conflict deformation occurs cracking the case where, influence
The quality of industrial products.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of structurally reasonable, the saving energy, and have one
Kind high-temperature calcination exhaust-gas treatment furnace.
The present invention is achieved by the following technical solutions:
A kind of high-temperature calcination exhaust-gas treatment furnace, including furnace body shell, it is characterised in that: furnace is installed in the furnace body shell
Internal shell, the furnace body inner casing two sides are symmetrically installed with gas-guide tube, and uniform intervals are equipped with multiple gas nozzles in the gas-guide tube,
The gas-guide tube is connected with gas storage case and gasifier section, the connection of furnace body inner casing upper end by export outside furnace body inner casing
There is escape pipe, which is connected with air inlet pipe, is equipped in the gap between the furnace body inner casing and furnace body shell
Coil pipe, the air inlet of the coil pipe are connected with the escape pipe of furnace body inner casing upper end installation, and the gas outlet of the coil pipe is integrally equipped with
Economizer bank, the economizer bank are coated on the outside of furnace body inner casing air inlet pipe, and the other end of the economizer bank is connected with external tail gas
Recyclable device.
The advantages and positive effects of the present invention are:
In the present invention, furnace body inner casing is installed in furnace body shell, furnace body involucrum plays heat-blocking action, and furnace body inner casing is then used for
Industrial products are accommodated, and it are sintered, gas nozzle, gas storage case and gasifier section match to be formed completely
Access calcines industrial products, and the coil pipe installed between furnace body shell and furnace body inner casing is used for will be after primary calcining
Exhaust gas export, and import in furnace body shell again, i.e., waste heat is subjected to recycling and plays the role of heat-insulation and heat-preservation, also forms heat
The interior circulation of amount, the economizer bank of the gas outlet connection of coil pipe, the then effect for being preheated to the air for flowing through air inlet pipe, nothing
Other heating equipments are needed, structure is simple, functional.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
Elaborate below by embodiment to the present invention, the embodiment be it is illustrative and not restrictive, no

Uniform intervals are equipped with multiple gas nozzles 12 in gas-guide tube, which is connected with gas storage by export outside furnace body inner casing
Case 1 and gasifier section 2, furnace body inner casing upper end are connected with escape pipe 3, which is connected with air inlet pipe
10, coil pipe 4 is installed in the gap between the furnace body inner casing and furnace body shell, the air inlet of the coil pipe is connected with furnace body inner casing
The escape pipe of upper end installation, the gas outlet of the coil pipe are connected with a side end of an economizer bank, the economizer bank packet by interface 9
The outside of furnace body inner casing air inlet pipe is overlayed on, the other end of the economizer bank is connected with external device for recovering tail gas.
In the present embodiment, partition 7 is installed on the inside of coil pipe between furnace body inner casing.
Use process of the invention:
The present invention in use, furnace body inner casing burning after exhaust gas exported through escape pipe, into coil pipe, flow back through coil pipe
The exhaust gas that has surplus heat of band import in economizer bank again, and finally export to device for recovering tail gas.
In the present invention, furnace body inner casing is installed in furnace body shell, furnace body involucrum plays heat-blocking action, and furnace body inner casing is then used for
Industrial products are accommodated, and it are sintered, gas nozzle, gas storage case and gasifier section match to be formed completely
Access calcines industrial products, and the coil pipe installed between furnace body shell and furnace body inner casing is used for will be after primary calcining
Exhaust gas export, and import in furnace body shell again, i.e., waste heat is subjected to recycling and plays the role of heat-insulation and heat-preservation, also forms heat
The interior circulation of amount, the economizer bank of the gas outlet connection of coil pipe, the then effect for being preheated to the air for flowing through air inlet pipe, nothing
