Embodiment 1

[0047] One of the specific implementations of a reactor with a surfacing lining structure of the present application, with reference to the prior art figure 1 , figure 2 , image 3 and Figure 4 As shown, the cylinder body 1 in the prior art is included, and the two ends of the cylinder body 1 are provided with sealing heads 3 , and the cylinder body 1 is provided with a material opening 4 , a detection opening and a supporting skirt 5 . The innovation of this application is that: the inner wall of the cylinder 1 is provided with a surfacing lining 2, and the weld beads 20 of the surfacing lining 2 are arranged along the axial direction of the cylinder 1. Any one or any combination of weld beads in the shape weld bead 22 or the linear combined weld bead 23. Compared with the prior art, the surfacing lining 2 structure of the present application has strong wear resistance, and the lining structure has a strong ability to withstand high-speed fluid erosion, and has good corr...

Embodiment 2

[0052] The second specific embodiment of a reactor with a surfacing lining structure of the present application, the main technical solution of this embodiment is the same as that of embodiment 1, and the features not explained in this embodiment are explained in embodiment 1 , which will not be repeated here. The difference between this embodiment and embodiment 1 is that the reference Image 6 As shown, the width of the edge is set to a fixed value E. During the operation, the edge E and point E of the adjacent two welding beads should be formed with a smooth and flat surface, and the edge F or G of the inappropriate weld bead should not be formed, and the point F should not be formed. There are deep uneven grooves on the connection surface due to insufficient lap joints, and it is difficult to clean up the welding slag debris at the bottom of the ditch, and it is also not conducive to the operation of the second layer of surfacing welding. A flat protrusion will hinder th...

Embodiment 3

[0054] The third specific embodiment of the application for changing a reactor with a surfacing lining structure, the main technical scheme of this embodiment is the same as that of embodiment 1, and the features that are not explained in this embodiment are adopted in embodiment 1 explanation, and will not repeat them here. The difference between this embodiment and Embodiment 1 is that the welding consumables of the surfacing lining 2 are all of the same material, and the surfacing lining 2 has a single-layer surfacing structure. This surfacing lining 2 structure is more suitable for mild corrosion conditions, simplifies the lining structure, and reduces costs.

Abstract

The invention relates to a reactor with an overlaying lining structure, comprising a barrel, wherein an overlaying lining is arranged on the inner wall of the barrel, a welding bead of the overlaying lining is arranged along the axial direction of the barrel, and the welding bead can be one or a combined welding bead of a spiral linear welding bead, an annular cascaded welding bead or a linear combined welding bead. Compared with the prior art, the overlaying lining structure is strong in wear resistant property, strong in capability of bearing high-speed scouring of fluid, and good in function of resisting high-temperature high-pressure medium corrosion, and an overlaying lining with the structure is good in flexible deformation function and can achieve integral compatible deformation along with thermal expansion and cold shrinkage of the barrel without cracking; and the overlaying lining also has the effects of being simple in structure, and capable of reducing control elements during processing, improving precision and operation efficiency, and prolonging the life of the reactor, thus being capable of meeting various chemical technological processes of high temperature reaction and heat exchange in the barrel, which have relatively high requirements.

Description

technical field [0001] This application relates to the technical field of various high-temperature and high-pressure reactors used in petroleum refining and chemical industry, coal chemical industry, chemical fertilizer industry, and other chemical equipment, especially to the hydrogenation reactor or desulfurization reactor technology that reacts through catalysts A reactor with a surfacing lining structure in the field. Background technique [0002] The basic structure of a chemical reactor generally includes a cylinder, heads arranged at both ends of the cylinder, openings for entering and exiting materials, openings for personnel detection, and supporting structures. The cylinder is made of steel plates or forgings. Generally, hydrogen reactors, desulfurization reactors, petrochemical reactors or coal chemical reactors all need catalysts to ensure the smooth progress of the reaction. In order to ensure the uniformity of the reaction, most of the reactors are installed ve...
