Description
Technical field
The present invention relates to smelting furnace tail gas collecting devices, the more particularly, to collapsible furnace of silicon carbide smelting exhaust collection
Cover.
Background technique
Silicon carbide is also known as diamond dust, hardness between corundum and diamond, have high mechanical strength, thermal stability it is good,
The series of advantages such as acid-alkali-corrosive-resisting, anti-thermal shock be good, are widely applied to the fields such as grinding tool, smelting iron and steel, military project.China
It is that maximum country silicon carbide production and used, the country are commonly linear type for the type of furnace of silicon carbide smelting and fix in the world
Furnace.It can generate during silicon carbide smelting largely with CO gas as main component, while with a small amount of SO2The production of gas
It is raw.The fixed furnace length of linear type is longer, and exhaust collection is relatively difficult, and there are risk of explosion.Country's common practice is at present
The direct emission after furnace charge surface is by the gas ignition of spilling, lacks necessary gas gathering mask.It not only results in so uncombusted
CO and SO2It is discharged into atmosphere and pollutes environment, and dust from flying causes operating condition in workshop severe, while valuable gases CO
Burning causes the significant wastage of the energy.
There are two types of modes for the processing of silicon carbide smelting tail gas recycle: (1) collecting after lighting to the gas for smelting generation, so
It concentrates afterwards and desulphurization and denitration processing is carried out to the tail gas of collection, discharged after up to standard；(2) concentration receipts are carried out to the gas for smelting generation
Collection, by being comprehensively utilized CO (such as combustion power generation, production industrial chemicals) after purified treatment.But both
Take-back model common keypoints are the gas for how collecting silicon carbide smelting generation or the tail gas after burning.Its difficult point mainly exists
In: (1) silicon carbide smelting furnace length longer, and the flue gas area that sheds is larger, needs to make huge gas gathering mask；(2) smelting process
Middle furnace charge head temperature is higher, and usually at 300 degrees Celsius or more, common gas gathering mask is difficult to apply under this operating condition；(3) it smelts
Contain CO in the tail gas of generation, there are the risks of explosion；(4) sic smelting furnace generally uses in groups, usual 4 ~ 6 smelting furnaces
It is one group, is required according to smelting process, gas gathering mask is needed in smelting process, but carry out taking off furnace, come out of the stove and fill after the completion of smelting
When furnace, gas gathering mask allows for removing completely.Therefore, still unmature currently on the market to be used for silicon carbide smelting exhaust collection
Bonnet system.
Summary of the invention
It is an object of that present invention to provide a kind of collapsible bonnets for silicon carbide smelting exhaust collection.
To achieve the above object, the present invention takes following technical proposals:
Collapsible bonnet of the present invention for silicon carbide smelting exhaust collection, including by movable support and it is hinged on the work
The bonnet frame that the fixation bracket of the character "door" form structure at dynamic bracket both ends is constituted, is disposed around the bonnet top of support by fixing piece
The bonnet face being fabricated from a flexible material with side；The movable support is by spaced multiple groups door shape frame and door shape branch
Support composition, is hinged by scissor expansion bracket respectively between the adjacent door shape frame and door shape support frame；Often
A door shape support frame and support bracket fastened bottom end are provided with rail wheel；It is axially disposed at the top of it in bonnet frame to have row
Air hose, the air-exhausting duct are connected by air pipe connector with bonnet frame, on the bottom wall of air-exhausting duct it is axially spaced offer it is more
A air inlet, the air outlet of air-exhausting duct extend except the fixation bracket of corresponding side and are connected by pipe collar with smoke exhaust pipe,
Temperature sensor and carbon monoxide detector are provided on the smoke exhaust pipe.
The air pipe connector is the hanging ring for being fixed on each door shape support frame and fixed cradle top, the air-exhausting duct
It is mutually fixed with the hanging ring of corresponding position.
The air-exhausting duct variable cross-section setting, it may be assumed that the diameter of air-exhausting duct is gradually increased from the air inlet to the air outlet.
The invention has the advantages that realizing that silicon carbide smelting tail gas and shove charge take off the collection of dust during furnace, to production field
Ground require it is lower, it is easy to operate.Using telescopic structure form, space occupied is reduced, conveniently in groups between sic smelting furnace
It calls.Bonnet is made of flexible material, and light-weight, from steel quantity consumption is largely reduced, manufacturing cost is low, while even if
Occur the urgent working of a furnace (such as tail gas explosion, spray furnace), flexible material can pressure release quickly, be unlikely to cause disaster, and be easy to repair
It mends.In addition, temperature sensor and carbon monoxide detector are arranged on the pipe fitting that bonnet external support casing is connected, be conducive to ensure
Bonnet takes out smoke evacuation system and stablizes safe operation, can add video monitoring system inside bonnet when necessary, for smelting operating condition reality
When monitor.
