Description
Technical field
The present invention relates to incineration of waste technical field, steam caused by especially a kind of cold slag of Rotation error and two combustions
Room separator.
Background technology
Rotary kiln incineration technique is the conventional process in dangerous waste incineration.According to national related demand of technical standard,
The Rotation error used in above-mentioned technique must be connected with dual firing chamber below.High temperature furnace caused by Rotation error
In the water cooling dreg cooling chamber of slag vertical landing below, because dreg cooling chamber is connected with dual firing chamber, when high temperature furnace slag falls into the water, production
Raw a large amount of steam enter dual firing chamber.The harm that a large amount of steam are brought into dual firing chamber is huge, greatly reduces dual firing chamber's fire resisting
The service life of material, add exhaust gas volumn, add the water content in flue gas so add to the corrosivity of equipment and after
The difficulty of continuous dedusting.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide steam caused by a kind of cold slag of Rotation error
With dual firing chamber's separator, the device has slagging channel between dual firing chamber and dreg cooling chamber, the slagging channel by setting cover plate,
Effectively in dreg cooling chamber, prevent steam from being caused into dual firing chamber to equipment vapor barrier caused by the cold slag of Rotation error
Damage.
To reach above-mentioned purpose, the technical scheme is that be achieved in：Caused by the cold slag of Rotation error
Steam and dual firing chamber's separator, separator are located at turn around between slag mouth and the dreg cooling chamber below kiln and dual firing chamber, this point
Include being connected with slag mouth lower section from device and the slagging channel of all round closure, the bottom of slagging channel have slag-drip opening,
There is the cover plate being flexibly connected with slagging channel at slag-drip opening.
Further improvement of the present invention also has, and the angle of slagging channel and horizontal plane is 60 ° ~ 70 °.Using this technology side
Case, it is ensured that the slag charge to have been burnt inside Rotation error quickly slides in slagging channel, is not detained in deslagging and leads to
In road, this inclination angle is that the angle of repose of slag caused by Rotation error is 3 ~ 5 ° in theory.
Further improvement of the present invention also has, and has air feed mouth on top surface on the slagging channel of slag-drip opening oblique upper；Should
The import of air feed mouth is connected with slagging channel.
Further improvement of the present invention also has, and slagging channel is the diminishing inverted tubaeform of sectional area from top to bottom.
Further improvement of the present invention also has, and the angle of cover plate and horizontal plane is 85 °.Using the technical program, cover plate exists
Deadweight is lower and slagging channel closes, and prevents cold slag combustion gas to rise completely.
Further improvement of the present invention also has, and cover plate bottom is in contact with the water surface of dreg cooling chamber so that high temperature furnace slag can be with
Quickly contacted with water.
Further improvement of the present invention also has, and slagging channel is the passage that castable refractory pours or uses fire resisting not
Become rusty passage made from steel, improves equipment durability.
Further improvement of the present invention also has, cover plate and slagging channel hinge connection.
Beneficial effects of the present invention：(1) device is provided with slagging channel between dual firing chamber and dreg cooling chamber, and the deslagging leads to
Road sets cover plate, and the cover plate is in closed state with slagging channel when being fallen without high temperature furnace slag, when cover plate under gravity will
Go out slagging channel sealing, when there is high temperature furnace slag whereabouts, can be impacted by slag charge and open cover plate, effectively by rotary kiln incineration
Vapor barrier prevents steam from causing to damage to equipment into dual firing chamber in dreg cooling chamber caused by the cold slag of stove；(2) portion on the cover board
Slagging channel be provided with dual firing chamber's air feed mouth, the basic air feed as dual firing chamber.The air feed can reduce the temperature of slag, reduce
The consumption of cold pulp water；Using the preheating temperature air feed of slag, energy-conservation is realized；The rising of cold slag steam in slag, can be stopped.

Fig. 1 is the structural representation of steam caused by the cold slag of Rotation error and dual firing chamber's separator.
In figure：1st, cover plate, 2, dual firing chamber, 3, slagging channel, 4, dreg cooling chamber, 5, rotary kiln, 6, air feed mouth, 7, slag mouth,
8th, slag-drip opening.
Embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
Embodiment 1：Steam caused by the cold slag of Rotation error and dual firing chamber's separator, separator are located at turn around kiln
Between 5 and the slag mouth 7 of the lower section of dual firing chamber 2 and dreg cooling chamber 4, the separator includes being connected with the lower section of slag mouth 7 and surrounding
The slagging channel 3 of closing, the bottom of slagging channel 3 have slag-drip opening 8, there is what is be flexibly connected with slagging channel 3 at slag-drip opening 8
Cover plate 1.
The angle of slagging channel 3 and horizontal plane is 60 ° ~ 70 °；The top surface on the slagging channel 3 of the oblique upper of slag-drip opening 8
On have air feed mouth 6；The import of the air feed mouth 6 is connected with slagging channel 3；Slagging channel be 3 from top to bottom sectional area gradually contract
Small inverted tubaeform；The angle of cover plate 1 and horizontal plane is 85 °；The bottom of cover plate 1 is in contact with the water surface of dreg cooling chamber 4；Slagging channel
3 are the passage that castable refractory pours or use passage made from fire resisting stainless steel；Cover plate 1 connects with the hinge of slagging channel 3
Connect.
In specific implementation, when no high temperature furnace slag falls, cover plate 1 encloses with the bottom of slagging channel 3 under gravity
Into closed cavity, when there is high temperature furnace slag whereabouts, high temperature furnace slag caused by incinerator is entered by slag mouth 7 and arranged in rotary kiln 5
Slag passage 3, under gravity high temperature furnace slag fall into the bottom of slagging channel 3 along slagging channel 3, and by slag-drip opening 8
The impact of cover plate 1 at place is opened, so as to fall into 4 in dreg cooling chamber；Now, cover plate 1 by vapor barrier caused by cold slag in dreg cooling chamber 4,
Prevent steam from causing to damage to equipment into dual firing chamber 2.Before improvement, there is the service life about 1.5 of the dual firing chamber of steam entrance
Year, the dual firing chamber, its service life 5-6 or so for not having steam to enter after improvement, cost is reduced, reduces environmental pollution.
