Abstract

The invention discloses a separate type pressure-bearing anti-corrosion device which comprises a corrosion resistant material layer, a pressure-bearing material layer, a corrosive pressure medium inlet, a corrosive pressure medium outlet and a pressure balancing system, wherein an area for containing a corrosive pressure medium is formed in the corrosion resistant material layer; a separate area is formed between the pressure-bearing material layer and the corrosion resistant material layer; the pressure balancing system comprises a first pressure balancing pipe, a second pressure balancing pipe, a liquid storage device and a liquid filling pipe, wherein one end of the first pressure balancing pipe and one end of the second pressure balancing pipe are respectively communicated with the area for containing the corrosive pressure medium and the separate area, the liquid storage device is used for communicating the other end of the first pressure balancing pipe with the other end of the second pressure balancing pipe, the liquid filling pipe is communicated with the second pressure balancing pipe, and separation media which are used for separating the corrosive pressure medium from a pressure guiding medium are led into the first pressure balancing pipe, the second pressure balancing pipe and the liquid storage device. By using the separate type pressure-bearing anti-corrosion device, on one hand, the problem of high cost is solved, and on the other hand, safety accidents are avoided. Additionally, the separate type pressure-bearing anti-corrosion device has the advantages of simple structure and convenience in implementation.

Description

technical field [0001] The invention relates to a pressure-bearing anti-corrosion device, in particular to a separated pressure-bearing anti-corrosion device. Background technique [0002] With the continuous advancement of science and technology, various complex and diverse chemical processes, environmental engineering processes, energy recovery and other related engineering processes have been developed rapidly. The development and progress of these processes will inevitably put forward more stringent requirements for the process equipment that realizes these processes, such as higher requirements for the material performance, economic cost, and safety performance of the equipment. At the same time, the pressure-bearing equipment used in the pressure-bearing system of various processes should have a higher strength grade. Especially in the high pressure state, in order to achieve the purpose of bearing higher pressure, the amount of pressure equipment materials is relativ...

Problems solved by technology

[0004] From the above discussion, it can be seen that how to reduce the cost of pressure-bearing equipment and improve the economic applicability of the equipment while meeting the high-pressure and corrosion-resistant process requirements is currently the The key to researching pressure-bearing equipment. At the same time, when the pressure of the corrosive medium in the high-pressure storage tank gradually increases until it exceeds the bearing range of the high-pressure storage tank, it will lead to safety accidents, and the consequences are very serious.
