Abstract
The invention discloses an evaporator in a high-temperature and high-pressure natural-circulation dry quenching waste heat boiler. The main technical scheme is as following: the evaporator adopts a natural-circulation style; the pipes forming the evaporator are all arranged into a horizontal disposition structure and adopt light tubes or extended surface tubes. Owing to adopting a complete horizontal-disposition evaporator in the dry quenching waste heat boiler, the arrangement of the heating surface in a vertical flue is more convenient and the workload of manufacturing and maintenance is greatly reduced; besides, the round through holes formed by the horizontal pipes extracted out of the vertical flue are also convenient for a treatment in a sealing way.
Description
Technical field
The present invention relates to the high-temperature high-pressure natural circulating dry coke quenching residual heat boiler field, refer more particularly to the natural convection loop evaporimeter in the vertical well gas flue of this kind boiler.
Background technology
In the vertical well gas flue of high-temperature high-pressure natural circulating dry coke quenching residual heat boiler, be provided with each heating surface---comprise economizer, double effect evaporator and two-stage superheater, wherein economizer adopts the forced circulation loop usually, double effect evaporator adopts natural convection loop, each heating surface particularly double effect evaporator and two-stage superheater adopts the form that hangs to install, from the boiler water cycle security, the evaporimeter of Natural Circulation adopts the arrangement of inclination in vertical well gas flue, promptly constitute the angle that has usually between the pipe of evaporimeter and the horizontal plane greater than 15 degree, perhaps, be provided with angle between that root pipe that directly is connected with fairlead in the evaporimeter at least and the horizontal plane.The shortcoming of the evaporimeter of the arrangement of above-mentioned this band tilting angle is: one: the space of occupying is bigger, makes the layout of each heating surface in the vertical well gas flue more complicated; Can on the vertical well gas flue wall, form ellipse hole when two, the pipe of Qing Xieing is drawn vertical well gas flue, and relatively more difficult to the encapsulation process of ellipse hole.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of layout that can make each heating surface in vertical well gas flue evaporimeter in the high-temperature high-pressure natural circulating dry coke quenching residual heat boiler more simply and easily is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the evaporimeter in the described high-temperature high-pressure natural circulating dry coke quenching residual heat boiler, be characterized in: described evaporimeter adopts the mode of Natural Circulation, and the pipe of composition evaporimeter all is arranged to horizontally disposed structure.
The further technical scheme of the present invention is: the pipe of composition evaporimeter recited above adopts light pipe or extended surface tube.
Advantage of the present invention is: the evaporimeter that adopts full horizontal mode to arrange, and more convenient to the layout of each heating surface in the vertical well gas flue, also significantly reduced the workload of making and keeping in repair simultaneously; The manhole that forms when in addition, the pipe of level is drawn vertical well gas flue also more helps encapsulation process.
Description of drawings
Fig. 1 is the arrangement schematic diagram of the evaporimeter in the high-temperature high-pressure natural circulating dry coke quenching residual heat boiler of the present invention.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, each heating surface in the vertical well gas flue of described dry coke quenching residual heat boiler comprises: economizer 1, first evaporator 2, second level evaporimeter 3, first order superheater 4 and second level superheater 5.Among the present invention, first evaporator 2 and second level evaporimeter 3 are the full horizontal tube evaporator of Natural Circulation, that is: all pipes that constitute evaporimeter are parallel with horizontal plane.In actual applications, the pipe that is adopted in the above-mentioned evaporimeter can be light pipe or extended surface tube, as: first evaporator 2 can adopt extended surface tube formation, second level evaporimeter 3 can adopt light pipe to constitute.In dry coke quenching residual heat boiler, adopt complete horizontally disposed evaporimeter, more convenient to the layout of each heating surface in the vertical well gas flue, also significantly reduced the workload of making and keeping in repair simultaneously; The manhole that forms when in addition, the pipe of level is drawn vertical well gas flue also more helps encapsulation process.
Claims (2)
1, the evaporimeter in the high-temperature high-pressure natural circulating dry coke quenching residual heat boiler is characterized in that: described evaporimeter adopts the mode of Natural Circulation, and the pipe of composition evaporimeter all is arranged to horizontally disposed structure.
2, evaporimeter as claimed in claim 1 is characterized in that: the pipe of described composition evaporimeter adopts light pipe or extended surface tube.
