Description
Technical field
It the utility model is related to cement produced with the dry method field, and in particular to a kind of efficiently double air-out cyclone preheaters.
Background technology
In System during New Style Dry-Process Production, the task of cyclone preheater is to make full use of in kiln tail discharge waste gas largely
Heat energy enters kiln to reduce system heat consumption or carry out the cement slurry feeding dore furnace after preheating in next step after raw meal powder is preheated
Suspended state carbonate decomposition process.Pre-heating system is formed by plural serial stage, from the point of view of optimization design, to different positions
The preheating cyclone cylinder put should have different requirements.In general, the cyclone cylinder as top preheater C1 is wanted to separative efficiency
Highest is sought, because the height of its separative efficiency plays decisive role to system separating effect.But the resistance damage of this grade of suspended state
Lose often also bigger.The situation of each new cyclone cylinder is also substantially such.Such as the new one cyclonic cylinder of Smith company, resistance
It is relatively low, air quantity people is handled, but the more conventional top cyclone cylinder of separative efficiency is much lower.Qinghai, this grade of cyclone cylinder in Shunchang cement plant
Separation effect rather under operating mode wind speed only have 90%-92%, the one-level cylinder of Huaxin Cement Factory is more slightly higher, but also only 93%-
93.5%, less than normal level.Fowler type cyclone cylinder is also roughly the same.And Japan, a little top cyclone cylinders of Germany, Ru Hongbao,
Top cyclone cylinder, the separating effect of small wild field, Kawasaki, Japanese cement company etc. are satisfactory, but drag losses is obvious high,
Such as the top cyclone cylinder in Yao County cement plant, separative efficiency is up to 96%-98% (chill), but drag losses is very high, handles air quantity
Than relatively low, the cyclone cylinder that size can only be used bigger works (3-4m/s) under relatively low section wind speed, otherwise can cause to hinder
Power skyrockets.
Heat exchange, minimum flow resistance, high separative efficiency of trying one's best, the capital expenditure most saved and operating are reliable to greatest extent
It is the dreamboat that preheater is pursued.
Utility model content
The utility model provides a kind of efficient double air-out cyclone preheaters that can be used in cement firing system, can not only
Enough ensure the separating effect of system, and drag losses is small, helps to give full play to the potentiality of kiln tail high-temperature blower, improves system
Clinker, there is the extremely strong market competitiveness.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that：
Efficiently double air-out cyclone preheaters, it is characterised in that including cyclone muff, the cylinder includes upper cylindrical shape
Cylinder and lower section divergent-cone wall, the interior upper discharge pipe that cylinder is set of cylindrical tube body；
Also include intake stack, the annular formed between the intake stack connecting cylinder shape cylinder and upper discharge pipe is empty
Between, and it is tangent with cylindrical tube and upper discharge pipe；
Also include lower discharge pipe, the lower discharge pipe is arranged in cylindrical tube body.
Foregoing efficient double air-out cyclone preheaters, it is characterised in that also including radiation shield.
Foregoing efficient double air-out cyclone preheaters, it is characterised in that under the radiation shield is arranged in conical tube body
Portion.
Foregoing efficient double air-out cyclone preheaters, it is characterised in that be respectively provided with the upper discharge pipe and lower discharge pipe
There is guide shell.
Foregoing efficient double air-out cyclone preheaters, it is characterised in that set dust to discharge below the divergent-cone wall
Mouthful.
Foregoing efficient double air-out cyclone preheaters, it is characterised in that the purifying gas flow after gas solid separation is strong through radiation shield
System changed course, rotates along water conservancy diversion drum outer wall and is discharged into exhaust duct from upper and lower air outlet.
The beneficial effects of the utility model are：Product technological transformation and newly-built, increase list while being effectively reduced energy resource consumption
Machine yield, strengthen the market competitiveness of company, strengthen the delayed effect of development in cement plant, be advantageously implemented the sustainable development of enterprise.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and detailed description：
Fig. 1 is schematic diagram of the present utility model.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings：

Also include intake stack (4), the annular formed between the intake stack connecting cylinder shape cylinder and upper discharge pipe
Space, and it is tangent with cylindrical tube and upper discharge pipe；
Also include lower discharge pipe (5), the lower discharge pipe is arranged in cylindrical tube body.
Foregoing efficient double air-out cyclone preheaters, it is characterised in that also including radiation shield (6).
Foregoing efficient double air-out cyclone preheaters, it is characterised in that under the radiation shield is arranged in conical tube body
Portion.
Foregoing efficient double air-out cyclone preheaters, it is characterised in that be respectively provided with the upper discharge pipe and lower discharge pipe
There is guide shell (7).
Foregoing efficient double air-out cyclone preheaters, it is characterised in that set dust to discharge below the divergent-cone wall
Mouthful.
Foregoing efficient double air-out cyclone preheaters, it is characterised in that the purifying gas flow after gas solid separation is strong through radiation shield
System changed course, rotates along water conservancy diversion drum outer wall and is discharged into exhaust duct from upper and lower air outlet.
Dusty gas tangentially enters cylinder from air inlet, the annular space between cylinder and discharge pipe, inner cylinder rotate to
Descend and progress into cone, centrifugal action of the dust in gas in by rotational flow field and separated with air-flow and collide barrel,
Kinetic energy is lost, discharge is fallen along barrel；Purifying gas flow after gas solid separation, force to alter course through radiation shield, revolved along water conservancy diversion drum outer wall
