Problems solved by technology

[0006] However, the construction method of the above-mentioned traditional integrated tubular heating furnace requires a large number of welding constructions on site, and the penetration of the furnace tube, the welding with the elbow, the radiographic detection of the weld, and the reflection of the weld defect Repairs, strict painting on the surface of the furnace wall and other processes require open-air and high-altitude construction on site. This kind of open-air high-altitude construction brings a lot of inconvenience to installation and construction, which is far from the HSE policy of modern engineering management.
Moreover, the wear-resistant and heat-insulating lining of the furnace wall is susceptible to weather, deformation, cracking, loosening, or rain failure
Therefore, this kind of open-air high-altitude

Embodiment 1

[0042] One of the specific implementations of a kind of assembleable circular tubular heating furnace of the present invention, such as image 3 As shown, a furnace shell 31, a furnace tube 32 and a burner are included. The furnace tube 32 is arranged in the furnace shell 31, and the burner is arranged in the furnace shell 31. Specifically, the burner can be arranged at the bottom of the furnace shell 31 for bottom firing , It can also be set on the top of the furnace shell 31 for top firing. Wherein, the furnace shell 31 is a furnace shell 31 assembled and connected by at least two furnace shell modules 311 .

[0043] Specifically, the furnace shell module 311 can be an arc-shaped furnace shell module 311, and there are two arc-shaped furnace shell modules 311, and the furnace shell 31 is formed by the arc-shaped furnace shell modules 311 interacting with each other along the radial direction. The assembled and connected furnace shell 31 has a circular cross-sectional shape....

Embodiment 2

[0047] The second embodiment of a kind of assembleable circular tubular heating furnace of the present invention, as Figure 4 As shown, the main technical solution of this embodiment is the same as that of Embodiment 1, and the features not explained in this embodiment adopt the explanation in Embodiment 1, and will not be repeated here, and are described in Figure 4 neutralize image 3 The same parts bear the same reference numerals. The difference between this embodiment and Embodiment 1 is that the furnace shell module 311 is an elliptical arc-shaped furnace shell module 311, and there are four elliptical arc-shaped furnace shell modules 311, and the furnace shell 31 is an elliptical arc-shaped furnace shell The modules 311 are assembled and connected to each other along the radial direction, and have a furnace shell 31 with an elliptical cross-sectional shape. Wherein, the elliptical arc-shaped furnace shell module 311 constituting the furnace shell 31 having an ellipt...

Embodiment 3

[0049] The third specific embodiment of a kind of assembleable circular tubular heating furnace of the present invention, as Figure 5 As shown, the main technical solution of this embodiment is the same as that of Embodiment 1, and the features not explained in this embodiment adopt the explanation in Embodiment 1, and will not be repeated here, and are described in Figure 5 neutralize image 3 The same parts bear the same reference numerals. The difference between this embodiment and Embodiment 1 is that the furnace shell module 311 is an arc-shaped furnace shell module 311 and a linear furnace shell module 311, wherein the arc-shaped furnace shell module 311 is provided with two, and the linear furnace shell module 311 There are two shell modules 311, and the furnace shell 31 is a furnace shell 31 with a cross-sectional shape of an oblong ring (the The long circular ring approximates the track shape of the sports field). Wherein, the arc-shaped furnace shell module 311 ...

Abstract

The invention relates to a cylindrical tube type heating furnace capable of being assembled, comprising a furnace shell, a furnace tube and a burner. The furnace tube is arranged in the furnace shell, the burner is also arranged in the furnace shell, wherein the furnace shell is composed of at least two furnace shell modules which are assembled and connected. As the heating furnace of the invention is provided with the furnace shell modules which can be assembled and connected and are applied to furnace shell, so that assembly and welding of the parts of the furnace shells can be carried out in a workshop of a manufacturing factory and then the furnace shells can be transported to the construction site to perform modularized 'block building' type construction. The mode in which the furnace shell modules are assembled to form the furnace shell changes the traditional construction mode in which a tubular heater is assembled and welded on site at the construction site, avoids the mess that various parts are scattered at the construction site, facilitates construction of large tubular heaters, leads to industrial application of the gradual implementation of modularized construction of industrial furnaces and has the characteristics of simple assemblage, low construction cost, short construction period and convenient overhauling.

Description

technical field [0001] The invention relates to heat exchange equipment technology, in particular to an assembleable circular tubular heating furnace. It can be used in petroleum refining and chemical industry, coal chemical industry, chemical fertilizer, air conditioner, air cooling, boiler, electric power facilities and other equipment industries to heat exchange equipment through medium heating or cooling, especially suitable for flue gas heat exchange of various chemical and fertilizer industrial furnaces equipment. Background technique [0002] Industrial furnaces are key equipment in the common production process in petrochemical plants. For example, tubular heating furnaces, reforming furnaces, and cracking furnaces for oil refining and petrochemical plants; high-temperature heating and high-temperature reaction gasifiers using coal as raw materials or primary reforming furnaces and secondary reforming furnaces using gas as raw materials for ammonia synthesis plants....
