Abstract

The invention discloses a novel annular airway of a dry quenching coke. The annular airway is characterized in that: the outlet part of the annular airway is provided with several inclined supports, and several horizontal supports are arranged between the inner ring and the outer ring of the annular airway; each inclined support comprises a support plate and a heatproof steel bar cage, two side ends of the support plate, which outwardly project, stick into the inner ring and a fireproof brick at the bottom of the outlet of the annular airway respectively, and heatproof steel bars in the heatproof steel bar cage between a base plate and a side plate are inserted into fireproof bricks; and each horizontal support comprises an epibolic heatproof plate and a heatproof steel bar cage, and heatproof steel bars in the heatproof steel bar cage are inserted into fireproof bricks of the inner ring and the outer ring. So when the deformation of the inner ring of the annular airway of the dry quenching oven generates, the projection of the inner ring along the circumference is restricted by the inclined supports and the horizontal supports, thereby the strength of the annular airway and an inclined withe is substantially improved, the collapse of the inner ring of the annular airway in the production process is avoided, and the service life and the service period of the dry quenching ovenare prolonged.

Description

A kind of novel dried ring shape air flue that puts out
Technical field
The dried stove that puts out that the present invention relates to use in the Dry Quenching Technology is applicable to coking industry.
Background technology
Environmental protection, power-saving technology that the coking industry Dry Quenching Technology is widelyd popularize for country Tenth Five-Year Plan Period, its principle of work is by nitrogen red-hot coke to be cooled off, the heat energy of nitrogen replacement is produced steam by waste heat boiler, and is used for generating.Dry coke quenching main process equipment is the dried stove that puts out, it mainly is comprised of the chamber that prestores, annular air channel, oblique flue, four parts of cooling room, prestore indoor filling red-hot coke, cooling room is nitrogen and red-hot coke thermal energy exchange zone, be provided with several oblique flues between chamber and the cooling room prestoring, as the nitrogen outlet passage after the heat exchange, the nitrogen of outflow leads to waste heat boiler from its outlet after annular air channel compiles.Because the refractory materials of ring is to rely on the basis of oblique flue refractory brick up to build by laying bricks or stones in the existing annular air channel, can be necessarily retrained in the degree of freedom of vertical direction, but radially only be relied on the refractory mortar constraint.And the annular air channel working condition is abominable, approximately 980 ℃ of temperature, and gas flow rate is large in addition, and annular air channel will be at circumferential direction generation bulging deformation.In case surmount the design load of circumferential expansion seam, the collapse accident of ring in the annular air channel can occur just when distortion, cause the dried stove that puts out to destroy and can not use.
Summary of the invention
Problem to be solved by this invention provides a kind of novel dried ring shape air flue that puts out, it is by increasing support at the existing dried ring shape air flue that puts out, limit the dried distortion of ring shape air flue under bad working environments of putting out, prevented that ring collapses in the annular air channel, prolonged dried work-ing life of putting out stove.
The dried ring shape air flue that puts out of the present invention, it is characterized in that: the outlet position at annular air channel is provided with several diagonal ligaments, is provided with several horizontal supports between the inner and outer ring of annular air channel.
Diagonal ligament comprises back up pad, heat-resisting Steel Reinforcement Cage, the cross-sectional shape of back up pad is " recessed " shape, the end of biside plate is projection outwards, extend into respectively in the refractory brick of interior ring and annular air channel outlet bottom, be provided with heat-resisting Steel Reinforcement Cage between base plate and the side plate, between back up pad and the heat-resisting Steel Reinforcement Cage, heat-resisting Steel Reinforcement Cage the inside all fills refractory castable, the heat-resisting reinforcing bar in the heat-resisting Steel Reinforcement Cage inserts in the refractory brick, the base of back up pad bottom is fixed on the refractory brick of annular air channel outlet bottom.
Horizontal support comprises outsourcing refractory plate, heat-resisting Steel Reinforcement Cage, between the heat-resisting Steel Reinforcement Cage of outsourcing refractory plate and its inside, heat-resisting Steel Reinforcement Cage the inside all fills refractory castable, heat-resisting reinforcing bar in the heat-resisting Steel Reinforcement Cage inserts in the refractory brick of inner and outer rings, outsourcing refractory plate bottom is placed on the supporting plate, and the supporting plate at two ends, the left and right sides is separately fixed on the refractory brick of inner and outer rings.
The present invention is by being provided with several diagonal ligaments between the interior ring of the outlet position of annular air channel and annular air channel, be provided with several horizontal supports between the inner and outer ring of annular air channel: the back up pad in the diagonal ligament, heat-resisting reinforcing bar stretch in the refractory brick of interior ring and annular air channel outlet bottom, and the base of back up pad bottom has further been reinforced back up pad; Heat-resisting reinforcing bar in the horizontal support extend in the refractory brick of inner and outer ring, and supporting plate has played the effect of supporting.Like this when dried when putting out in the ring shape air flue ring and deforming, diagonal ligament and horizontal support have all limited it along circumferential projection, greatly improved the intensity of belt air channel and oblique mid-feather, avoid the in process of production interior environment-development life of annular air channel to collapse, prolonged dried work-ing life and the life cycle of putting out stove.
