Description
Technical field
The utility model relates to smelting furnace tail gas collecting devices, the more particularly, to folding of silicon carbide smelting exhaust collection
Formula bonnet.
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
The utility model aim is to provide a kind of collapsible bonnet for silicon carbide smelting exhaust collection.
To achieve the above object, the utility model takes following technical proposals:
Collapsible bonnet described in the utility model for silicon carbide smelting exhaust collection, including by movable support and hingedly
In the bonnet frame that the fixation bracket of the character "door" form structure at the movable support both ends is constituted, the furnace is disposed around by fixing piece
The bonnet face that cage top surface and side are fabricated from a flexible material；The movable support by spaced multiple groups door shape frame and
Door shape support frame composition, passes through scissor expansion bracket phase respectively between the adjacent door shape frame and door shape support frame
Hingedly；Each door shape support frame and support bracket fastened bottom end are provided with rail wheel；It is located at its top in bonnet frame along axial direction
It is provided with air-exhausting duct, the air-exhausting duct is connected by air pipe connector with bonnet frame, axially spaced on the bottom wall of air-exhausting duct
Offer multiple air inlets, the air outlet of air-exhausting duct extends except the fixation bracket of corresponding side and by pipe collar and smoke exhaust pipe
It is connected, is provided with temperature sensor and carbon monoxide detector 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 row
Air hose and the hanging ring of corresponding position are mutually fixed.
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 utility model advantage is the collection for realizing that silicon carbide smelting tail gas and shove charge take off dust during furnace, to life
It is lower to produce site requirements, it is easy to operate.Using telescopic structure form, space occupied, convenient sic smelting furnace in groups are reduced
Between call.Bonnet is made of flexible material, and light-weight, from steel quantity consumption is largely reduced, manufacturing cost is low, simultaneously
Even if the urgent working of a furnace (such as tail gas explosion, spray furnace) occurs, flexible material can pressure release quickly, be unlikely to cause disaster, and easily
In repairing.In addition, temperature sensor and carbon monoxide detector are arranged on the pipe fitting that bonnet external support casing is connected, be conducive to
It ensures that bonnet takes out smoke evacuation system and stablizes safe operation, video monitoring system can be added inside bonnet when necessary, be used for smelter
Condition real time monitoring.
