Abstract
The utility model relates to complete equipment for tail gas treatment of a graphitization furnace. The complete equipment is provided with a quenching spray cooling tower, a secondary absorption tower, a tertiary absorption tower and a quaternary absorption tower which are sequentially in series connection. An air inlet of the quenching spray cooling tower is connected with the graphitization furnace through an exhaust pipe, and an air outlet of the quaternary absorption tower is connected with a blowdown stack through an exhaust pipe. As the temperature of tail gas exhausted from the graphitization furnace is extremely high, a fresh air supplementing joint and an emergency fresh air port are further arranged at the air inlet of the quenching spray cooling tower to reduce the temperature of the tail gas and facilitate subsequent treatment. By means of washing absorption of the quenching spray cooling tower, the secondary absorption tower, the tertiary absorption tower and the quaternary absorption tower, the tail gas exhausted from the graphitization furnace can be discharged in a standard reaching manner.
Description
Technical field
The utility model relates to a kind of graphitizing furnace vent gas treatment complete set of equipments.
Background technology
Present graphitizing furnace technology is that chlorine and fluorine gas are fed in the high temperature furnace; Itself and graphite are reacted, and the exhaust temperature that therefore in graphitizing furnace, produces is also very high, and contains sour gas such as residual chlorine, hydrogen chloride; Have corrosivity, could discharge after must effectively handling.
The utility model content
The purpose of the utility model provides a kind of complete set of equipments that can handle the tail gas of graphitizing furnace.
The technical scheme that realizes the utility model purpose is: a kind of graphitizing furnace vent gas treatment complete set of equipments; Has the chilling spraying cooling tower that is connected in series successively; Two-level absorption tower; Three grades of absorption towers and level Four absorption tower, the air inlet of described chilling spraying cooling tower is connected with graphitizing furnace through blast pipe, and the air outlet on level Four absorption tower passes through blast pipe and is connected with blowdown stack.
Described blowdown stack is fixed by the well cabinet frame, and the bottom of blowdown stack also is connected with centrifugal blower.
The air inlet place of described chilling spraying cooling tower also is provided with new wind and mends interface.
Described chilling spraying cooling tower also is connected with a underground circulating slot.
Blast pipe between described chilling spraying cooling tower and the graphitizing furnace adopts fire-retardant type fiberglass to make.
The utlity model has positive effect: because the exhaust temperature that graphitizing furnace is discharged is very high; Therefore be provided with new wind at the air inlet place of chilling spraying cooling tower and mend interface and emergent fresh wind port; Be convenient to subsequent treatment to reduce exhaust temperature, through over-quenching spraying cooling tower, two-level absorption tower; The washing on three grades of absorption towers and level Four absorption tower absorbs to be handled, but the tail gas qualified discharge that graphitizing furnace is discharged.
Description of drawings
For the content that makes the utility model is expressly understood more easily,, the utility model is done further detailed explanation, wherein below according to specific embodiment and combine accompanying drawing
Fig. 1 is the structural representation of the graphitizing furnace vent gas treatment complete set of equipments of the utility model.
The specific embodiment
See Fig. 1, contained chlorine, the acid gas of hydrogen chloride for guaranteeing to reach the treatment effect of design, adopt the level Four washing absorption tower to handle in the graphitizing furnace vent gas treatment complete set of equipments main processing tail gas of the utility model.Because what handle is acid high-temperature gas, therefore, described scrubbing tower all adopts glass-reinforced plastic material.
The graphitizing furnace vent gas treatment complete set of equipments of the utility model; Mainly has the chilling spraying cooling tower 1 that is connected in series successively on the structure; Two-level absorption tower 2; Three grades of absorption towers 3 and level Four absorption tower 4, the air inlet 1.1 of described chilling spraying cooling tower 1 is connected with graphitizing furnace 10 through blast pipe 9, and the air outlet 4.1 on level Four absorption tower 4 passes through blast pipe and is connected with blowdown stack 6.Blowdown stack 6 is fixing by well cabinet frame 7, and the bottom of blowdown stack 6 also is connected with centrifugal blower 8.Air inlet 1.1 places of chilling spraying cooling tower 1 also are provided with the emergent fresh wind port 1.4 and temperature controller 1.5 that new wind is mended interface 1.3 and shielded when overheated; Wherein, the temperature of temperature controller 1.5 monitoring air inlets 11 is when temperature is too high; The emergent fresh wind port 1.4 of control is opened; Input cold wind guarantees the processing device security operation to reduce the temperature that gets into tail gas, when temperature is just often then closed emergent fresh wind port 1.4.Blast pipe 1.2 between described chilling spraying cooling tower 1 and the graphitizing furnace 10 adopts fire-retardant type fiberglass to make.
Described chilling spraying cooling tower 1,2, three grades of absorption towers of two-level absorption tower 3 and level Four absorption tower 4; Its housing structure is basic identical, and the bottom of tower body all is a water tank, and the top of water tank is the spray tower body; The spray tower body the bottom be provided with air inlet, the top is provided with exhaust outlet, the spray tower body in from top to down the compartment of terrain be provided with two layers or three layers of packing layer; Each layer packing layer top all correspondence is provided with spray system, and the top in the spray tower body also is provided with water collection device, also is provided with manhole on the tower body.
Owing to contain dust in the waste gas that graphitizing furnace 10 is discharged and temperature is very high; The effect of chilling spraying cooling tower 1 mainly is gentle dedusting; Therefore, chilling spraying cooling tower 1 adopts chilling spraying and dedusting method, because of containing dust in the waste gas; Result in blockage easily in the chilling spraying cooling tower 1, the filler in the chilling spraying cooling tower 1 adopts the high temperature resistant filler of the less extraordinary dedusting of resistance.Because the temperature of waste gas is higher, the circulating water temperature of chilling spraying cooling tower 1 is prone to raise, so the water tank of chilling spraying cooling tower 1 connects a underground circulating slot 11 in addition, the dischargeable capacity of underground circulating slot 11 is about 60M
3, it is anticorrosion that cell body is that Reinforced Concrete Structure adds FRP.Additionally descend circulating slot 11 also to play the effect of deposition dust, need regularly clear up.Add sodium hydroxide lye in the circulation fluid of chilling spraying cooling tower 1, the pH value of circulation fluid is remained on about 10, be used for the absorption of the sour gas of waste gas.The circulation fluid on 2, three grades of absorption towers of two-level absorption tower 3 and level Four absorption tower 4 is a sodium hydroxide solution also, and concentration is at 5%-10%.After the washing absorption processing on process two-level absorption tower 2, three grades of absorption towers 3 and level Four absorption tower 4 was up to standard, waste gas was discharged through blowdown stack 6 by centrifugal blower 8.
Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
