Large chemical equipment assembled by plate-shaped modules with anticorrosion liners and manufacturing method of chemical equipment

Abstract

The invention discloses large chemical equipment assembled by plate-shaped modules with anticorrosion liners and a manufacturing method of the chemical equipment. The chemical equipment comprises the metal plate-shaped modules with flanges at the peripheries, wherein the metal plate-shaped modules are connected through bolts; the anticorrosion liner layers are lined on the inner surfaces and the flange sealing surfaces of the metal plate-shaped modules. According to the chemical equipment, a conventional design and manufacture concept is broken through, and any lined equipment with the diameter more than 4 m can be designed into large integral equipment assembled by a plurality of plate-shaped modules, so that the equipment can be manufactured on a production line in a manufacture enterprise and assembled on site, and the effects of reducing the cost and guaranteeing the quality are achieved.

Description

technical field [0001] The invention relates to a plate-shaped module assembled large-scale chemical equipment with an anti-corrosion lining and a manufacturing method. Background technique [0002] In order to overcome the corrosion of many chemical media on containers, chemical reaction equipment and other equipment during storage and reaction, steel-lined PTFE, steel-lined PE, steel-lined PO chemical storage tanks, chemical reactor reaction towers, chemical Heat exchangers have been used more and more widely. [0003] Historically, for all large-scale chemical equipment with a diameter of more than four meters, the entire steel shell has been manufactured on site, and then lined with anticorrosion on site. This traditional manufacturing method not only increases the difficulty of construction and increases the cost, but more importantly, it is difficult to ensure the quality of lining anti-corrosion, which brings great hidden dangers to the service life of the equipment ...

AI Technical Summary

Problems solved by technology

This traditional manufacturing method not only increases the difficulty of construction and increases the cost, but more importantly, it is difficult to ensure the quality of lining anti-corrosion, which brings great hidden dangers to the service life of the equipment and long-term safe production.

Especially for some large storage tanks that must be lined with PTFE, large-diameter reaction towers, reaction kettles, large chemical gas cabinets, and large heat exchangers, when PTFE lining is performed on site, manual hot air welding can only be used. It is more difficult to complete, the strength of PTFE weld is low, and the reliability of the whole equipment is difficult to guarantee
