Embodiment Construction

[0015] Below in conjunction with accompanying drawing this equipment is described in detail as follows:

[0016] A prestressed pressure vessel, which is composed of axial prestressed tendons 2, circumferential prestressed tendons 4, prestressed concrete blocks 3, etc., and the detachable prestressed concrete blocks 3 The stress tendon 4 is fixed into a cylinder, and the inner wall of the prestressed concrete block 3 is provided with an insulating material layer 5. The inner wall of the insulating material layer 5 has a bushing 10, and the bushing 10 is used to hold the solution, and an end cap is arranged at the upper end of the container 1. The maintenance of the large container is facilitated, the middle, upper and bottom are provided with pipes leading to the outside of the container, and the middle pipe 7 and the upper pipe 8 can be used to enter and exit the solution. The prestressed concrete block 2 is provided with a plurality of axial prefabricated holes 12 in the axia...

Abstract

The invention discloses a prestress pressure container which comprises axial prestressed tendons, annular prestressed tendons and prestressed concrete blocks, and the prestress pressure container is characterized in that the concrete blocks are fixed by the axial prestressed tendons and the annular prestressed tendons to form a cylinder; the inner wall of each concrete block is provided with a heat insulating material layer, the inner wall of the heat insulating material layer is provided with a lining, the upper end of the container is provided with an end cover, and the middle part, the upper part and the bottom part of the container are provided with pipelines which are led to the outside of the container; and the pressure container device is suitable for large middle-low pressure containers, and is particularly suitable for large-scale district heating containers. The stress inverse to the working pressure of the container is applied to the container first, so that the stress tolerance capability of the pressure container is improved. The container is formed by splicing multiple sections of concrete blocks which can be dismounted, thereby avoiding the difficulties that the manufacturing process of general large pressure containers is complicated, the transportation is difficult and the like.

Description

technical field [0001] The invention belongs to the field of pressure vessel equipment, in particular to a prestressed pressure vessel. Background technique [0002] Pressure vessels are widely used in the production field, and are key equipment necessary for many industries such as chemical industry, oil refining, light industry and energy. It has two types of structures, single-layer and multi-layer. Compared with the single-layer structure, the multi-layer structure not only solves the difficult problem of thick-walled manufacturing, but also has special advantages in the rational use of materials and safety. Therefore, multi-layer containers, especially multi-layer high-pressure containers, are used as pressure vessels. A structural form that has been widely used in various fields of process industry production. For example, ammonia synthesis towers and urea synthesis towers in the chemical industry, hydrogenation reactors in petroleum refining, fully multi-layer high-p...
