In view of this, the purpose of the present invention is to provide a kind of heat-exchanger rigs.
To achieve the goals above, technical scheme of the present invention provides a kind of heat-exchanger rig, is used for dry coke quenching equipment, changes
Thermal has tube sheet, including：First cylinder and the second cylinder made of being enclosed by shell；Multiple ash pipelines are set to first
In body and the second cylinder, the both ends of ash pipeline are connected to corresponding tube sheet respectively；At least one expansion joint, the first cylinder and second
Cylinder is connected by expansion joint.
Optionally, heat-exchanger rig further includes：Baffle plate is fixed on perpendicular to ash pipeline in shell.
Optionally, heat-exchanger rig further includes：Stay-bolt is fixed on the both ends of expansion joint along the telescopic direction of expansion joint.
Further, heat-exchanger rig further includes：Two support elements are opposite to be set to outside shell；Two elastic components, are respectively arranged on
The lower section of support element.
Compared with the existing technology, beneficial effects of the present invention are as follows：
By using tubular heat exchanger principle, the heat-exchanger rig for dry coke quenching equipment to be not easy block, it is existing to reduce leakage
As the possibility of generation, and then make the production that dry coke quenching equipment is safe efficient, stablizes.
The additional aspect and advantage of the present invention will become apparent in following description section, or practice through the invention
Recognize.
Description of the drawings
Fig. 1 shows the structural schematic diagram of the heat-exchanger rig of a specific embodiment according to the present invention；
Wherein, the correspondence in Fig. 1 between reference numeral and component names is：
10 first cylinders, 102 upper flanges, 20 second cylinders, 202 lower flanges, 30 ash pipelines, 40 baffle plates, 50 pull rod spiral shells
Bolt, 60 expansion joints, 70 inlet tubes, 80 outlets, 90 support elements, 100 elastic components.
Specific implementation mode
The present invention is further described in detail with reference to the accompanying drawings and detailed description.It should be noted that
Feature in embodiments herein and embodiment can be combined with each other.
Many details are elaborated in the following description to facilitate a thorough understanding of the present invention, still, the present invention may be used also
To be implemented different from other modes described here using other, therefore, protection scope of the present invention is not by described below
Specific embodiment limitation.
According to some embodiments of the present invention referring to Fig. 1 descriptions.
As shown in Figure 1, according to the heat-exchanger rig of one embodiment provided by the invention, it to be used for dry coke quenching equipment, heat exchange dress
It sets with tube sheet, including：First cylinder 10 and the second cylinder 20 made of being enclosed by shell；Multiple ash pipelines 30 are set to first
In cylinder 10 and the second cylinder 20, the both ends of ash pipeline 30 are connected to corresponding tube sheet respectively；At least one expansion joint 60, first
Cylinder 10 and the second cylinder 20 are connected by expansion joint 60.
To the water cold sleeve phenomenon analysis of damage, the water cold sleeve used now is by 46 single independent small water-cooled jackets
Pipe combination uniformly arranges, and the annular seal head in its bottom is cracking, and cooling water is caused to seal in coke powder side, into coke dry quenching furnace
System.The reason is that recirculating cooling water system be it is open, northern weather dust storm is big, the sundries such as leaf, polybag, sandy soil be easy into
Enter pond of cooling tower, and independent small water cold sleeve cooling water flow conduits are narrow, only 9mm wide, easily silting, water flow velocity gradually become
Slowly, final cutout.The heat displacement of 600 DEG C or so of high temperature coke powder is not walked at this time, causes the weld seam at annular seal head position weak
Place cracking, it is final to damage, cooling water string occurs and leaks phenomenon.
The heat-exchanger rig of the present embodiment is tubular heat exchanger, and coke powder is flowed down from top to bottom by ash pipeline 30, first
Body 10 and the second cylinder 20 are connected and are connected by expansion joint 60, and to absorb the swell increment of internal ash pipeline 30, guarantee every is defeated
The end of ash pipe 30 will not be because of expanding with heat and contract with cold and drawing crack, thus heat exchanger is not easy block, is not easy string leakage, reduces leakage phenomenon hair
Raw possibility, and then make the production that dry coke quenching equipment is safe efficient, stablizes.
In the present embodiment, expansion joint 60 is the preferable corrugated stainless steel tubing expansion joint 60 of ductility, Φ 1724 × 24.Ash pipeline
30 be the conventional heat refractory 20G seamless steel pipes of Φ 159 × 10, ensures original circulation area, prevents dry coke quenching from floating burnt accident occur
When, the bulk coke blocking that is blown afloat.Heat-exchanger rig is connect by upper flange 102 with upper storage ash bucket, by lower flange 202 under
Store up ash bucket connection.
Heat-exchanger rig further includes cooling medium inlet pipe 70, and cooling media outlet pipe 80, and cooling medium is through inlet tube 70
It flows into inside heat-exchanger rig, coke powder is cooled down, then flowed out via outlet 80.
Optionally, heat-exchanger rig further includes：Baffle plate 40 perpendicular to ash pipeline 30, and is fixed in shell.
Baffle plate 40 is used to increase the flow time of cooling medium, to reach the sufficient purpose of heat exchange.
Optionally, heat-exchanger rig further includes：Stay-bolt 50 is fixed on expansion joint 60 along the telescopic direction of expansion joint 60
Both ends.
Stay-bolt 50 will not distort cracking for 60 weld seam of expansion joint in transport or installation process, play a supporting role.
Further, heat-exchanger rig further includes：Two support elements 90 are opposite to be set to outside shell；Two elastic components 100, point
Not She Yu support element 90 lower section.
Heat-exchanger rig is right angle setting, weighs 20 tons or so, and the clamp force for depending merely on bolt is thiner, so needing in lower part
Increase support element 90 at support platform to protect.Since expanding with heat and contract with cold for internal ash pipeline 30 must drive the first cylinder 10 and second
20 synchronization telescope of cylinder, otherwise weld seam is easy drawing crack, therefore 90 lower section of support element is fixed with elastic component 100, is stayed to expand with heat and contract with cold
There is flexible surplus.Elastic component 100 in the present embodiment is spring.
Technical scheme of the present invention is described in detail above in association with attached drawing, technical solution through the invention, the first cylinder
It is connected by expansion joint with the second cylinder, to absorb the swell increment of internal ash pipeline, ensures that the end of every ash pipeline will not be because
To expand with heat and contract with cold and drawing crack, thus heat exchanger is not easy block, is not easy string leakage, reduces the possibility that leakage phenomenon occurs, and then make
The production that dry coke quenching equipment is safe efficient, stablizes.
The above, only presently preferred embodiments of the present invention, not does limitation in any form to the present invention, appoints
What those skilled in the art, without departing from the scope of the present invention, when in the technology using the disclosure above
Hold the equivalent embodiment made a little change or be modified to equivalent variations, as long as being the content without departing from technical solution of the present invention,
According to the technical essence of the invention to any simple modification, equivalent change and modification made by above example, this is still fallen within
The range of inventive technique scheme.
