Abstract
The utility model relates to a centripetal concave-cone-shaped radiation furnace tube of a cylindrical heating furnace, belonging to a furnace tube used for the heating furnace. The furnace tubes are vertically arranged along the periphery of a furnace body; every two lower ends of the adjacent furnace tubes are connected with each other in a U-shaped manner, the bending transverse section at the upper ends thereof declines towards the axial center of the furnace body, every two upper ends thereof are connected with each other in a U-shaped manner and arranged in a long-short alternation and concave-cone-shaped space manner; and the tube bundle of the transverse section at the top of the furnace tube takes on a concave cone with symmetrical space axis. The centripetal concave-cone-shaped radiation furnace tube has the advantages of reasonable design and simple structure; and under the premise of no change of the whole structure dimension of the furnace body, the radiation furnace tube is additionally arranged in the furnace body so as to increase the heat exchange area of the furnace tube, fully utilize the space of a radiation chamber, and also increase the radiation rate of the upper part of the furnace tube of the radiation chamber, thus effectively increasing the heat load of the heating furnace, reducing equipment investment, improving the comprehensive efficiency of the heating furnace, effectively enlarging the heat exchange area of the furnace tube, and improving the production capacity of the device.
Description
Technical field
The utility model belongs to the heating furnace boiler tube, particularly relates to entad concave cone shape radiating furnace tube of a kind of cylindric heater.
Background technology
In the petrochemical industry process, heating furnace is the most basic, imperative equipment, it simultaneously also is the key equipment that petrochemical industry production capacity size is played decisive factor, the thermic load size of heating furnace is the working ability of decision petrochemical equipment directly, therefore, under the situation of comparable size structure, it is particularly important that the thermic load of raising heating furnace shows.According to present science and technology development present situation, closely bound up with the thermic load of petrochemical industry heating furnace is that the heat exchange area of heating furnace radiation chamber boiler tube is (because of the surface heat intensity of boiler tube is limited to certain limit, can not infinitely increase), the boiler tube heat exchange area that therefore improves the heating furnace radiation chamber is the effective way that improves the heating furnace thermic load.And existing heating furnace radiation chamber has influenced heat exchange area because its inner boiler tube layout is unreasonable, has limited the production capacity of device.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and entad concave cone shape radiating furnace tube of a kind of cylindric heater is provided.
Cylindric heater of the present utility model is concave cone shape radiating furnace tube entad, described boiler tube be along two two U-shapeds that body of heater ring Zhou Shuli arranges, its lower end is adjacent connect, horizontal section of the bending of its upper end has a down dip, still connects for adjacent termination two two U-shapeds and length alternately is space concave cone shape and arranges to the body of heater axle center.
As further improvement of the utility model, the tube bank that the top of boiler tube is horizontal section is the concave cone shape of spatial axis symmetry.
As further improvement of the utility model, comprise on the top of boiler tube with the vertical U-shaped of horizontal section two two tube bank separately being connected.
Cylindric heater of the present utility model is concave cone shape radiating furnace tube entad, reasonable in design, simple in structure, be under the prerequisite of body of heater general structure size constancy, in body of heater, set up radiating furnace tube and increase the boiler tube heat exchange area, make full use of the radiation chamber space, also increased the radiance on radiation chamber boiler tube top, thus improve effectively heating furnace thermic load, reduce equipment investment, improve the overall efficiency of heating furnace, strengthen the heat exchange area of boiler tube effectively, improved the production capacity of device.
Description of drawings
Figure of description is the entad structural representation of concave cone shape radiating furnace tube of the utility model cylindric heater.
The specific embodiment
Cylindric heater of the present utility model is concave cone shape radiating furnace tube entad, described boiler tube 1 be along two two U-shapeds that body of heater ring Zhou Shuli arranges, its lower end is adjacent connect, horizontal section 2 of the bending of its upper end have a down dip, still connect for adjacent termination two two U-shapeds and length alternately is space concave cone shape and arranges to the body of heater axle center.The tube bank that the top of boiler tube 1 is horizontal section 2 is the concave cone shape of spatial axis symmetry.
Cylindric heater of the present utility model is concave cone shape radiating furnace tube entad, described boiler tube 1 be along two two U-shapeds that body of heater ring Zhou Shuli arranges, its lower end is adjacent connect, horizontal section 2 of the bending of its upper end has a down dip, still connects for adjacent termination two two U-shapeds and length alternately is space concave cone shape and arranges to the body of heater axle center, be vertical U-shaped connection between horizontal section 2 two two tube banks separately.。The tube bank that the top of boiler tube 1 is horizontal section 2 is the concave cone shape of spatial axis symmetry.
