Example Embodiment

[0030] Hereinafter, preferred embodiments of the present invention will be described in detail based on the drawings.

[0031] Such as Figure 4 to Figure 6 As shown, the composite tower support cylinder of the present invention includes a first support cylinder 1 and a second support cylinder 6;

[0032] The first support cylinder 1 and the second support cylinder 6 are connected end to end to form a cylindrical cylinder. The cylindrical cylinder is provided with a synthesis gas outlet 2. The synthesis gas outlet 2 is a semicircular hole, and the synthesis gas outlet 2 is directly above the The connecting seam is a short longitudinal seam 4, and the connecting seam opposite to the short longitudinal seam 4 is a long longitudinal seam 3. Both the first support cylinder 1 and the second support cylinder 6 are densely distributed with regularly arranged circular holes 5.

[0033] The manufacturing method of the support cylinder of the synthesis tower, such as Figure 7 with Figure 8...

Abstract

The invention discloses a synthesis tower supporting cylinder and a manufacturing method thereof. In the prior art, whole plate unloading is adopted, dense holes are drilled, coil welding moulding isperformed, artificial plasma cutting is carried out to form a syngas outlet, the material consumption is large, the surface quality of the syngas outlet is bad, and the drilling efficiency is low. Theinvention aims to solve the problem mentioned above. A novel designing-manufacturing method is provided and comprises following steps: dual vertical seam frame processing, dense hole overlap-drilling, and CNC plasma cutting to form a syngas outlet. The synthesis tower supporting cylinder material utilization rate is improved, the manufacturing cost is reduced, and the product surface quality is improved.

Description

technical field [0001] The invention relates to a design and manufacturing method of a support cylinder, in particular to a synthesis tower support cylinder and a manufacturing method, belonging to the technical field of ethylene glycol synthesis towers and the design and manufacture technology of cylinder inner parts with the same structure as pressure equipment. Background technique [0002] For a long time, the refractory ball catalyst stainless steel support cylinder of ethylene glycol synthesis tower or synthesis reactor has non-pressurized internal parts, densely arranged square holes of φ12-24mm, and large-sized semi-circular holes as synthesis gas outlet channels. The existing method has been adopting the manufacturing method of blanking the whole plate of the cylinder, processing dense holes, rolling, manual plasma cutting and grinding the semi-circular holes, which consumes a lot of materials, the surface quality of the semi-circular holes is poor, and the drilling ...
