Technical Field
The invention relates to the technical field of petrochemical production devices, in particular to a U-shaped conjoined pressure container.
Background
The pressure container is a closed device which contains gas or liquid and bears certain pressure. The pressure container is widely applied to the fields of petroleum, chemical engineering, aerospace, medical treatment and the like. It is classified into the following according to the grade of bearing pressure: low pressure vessels, medium pressure vessels, high pressure vessels, and ultra high pressure vessels. Vertical pressure vessels are common in pressure vessels and are most widely used. In recent years, with the development of petrochemical devices towards large-scale production, the volume of a reactor becomes larger and higher, and with the increase of the diameter of the container and the production scale, the material flow in the reaction process is large, and the medium flow speed is high, so that vibration is easily caused.

Detailed Description
The present invention will be described in detail below with reference to specific embodiments and the accompanying drawings.
The U-shaped conjoined pressure vessel of the embodiment is shown in fig. 2 and 3, and comprises a main cylinder body 1 and three auxiliary cylinder bodies 2 which are vertically arranged, wherein the three auxiliary cylinder bodies 2 are uniformly distributed around the circumference of the main cylinder body 1 and leave a distance with the main cylinder body 1, the side wall of the upper end of the main cylinder body 1 is provided with three side ports, the three side ports are uniformly distributed around the longitudinal axis of the main cylinder body 1, the side ports and the auxiliary cylinder bodies 2 are arranged in a staggered manner, and the upper ends of the three auxiliary cylinder bodies 2 are respectively provided with an upper port. The three side interfaces of the main cylinder body 1 and the upper interfaces of the three auxiliary cylinder bodies 2 are communicated through different bent pipes 3 respectively, the bent pipes 3 are connected with the side interfaces of the main cylinder body 1 and then transversely extend towards the direction far away from the corresponding auxiliary cylinder bodies 2, extend upwards to arch and bend, and then are downwards connected with the upper ports of the corresponding auxiliary cylinder bodies 2. So make three vice barrel 2 and three return bend 3 high in spatial symmetry degree, the structure is more stable, can reduce the interior medium velocity of flow of return bend during operation and the vibration that produces fast.
Compared with the traditional pressure container with a single cylinder, the pressure container has the advantages of balanced stress, uniform erosion corrosion (corrosion resistance and long service life) and capacity expansion under the same pipe diameter due to the adoption of the integral structure of the auxiliary cylinder and the bent pipe.
Under the condition of equal productivity, because the bent pipe and the auxiliary cylinder body are added, the pipe diameter of each main cylinder body or each auxiliary cylinder body can be reduced, and the bent pipe has better flexibility under the condition of reducing the pipe diameter.
In this embodiment, the cross-sectional shape of the end of the elbow 3 is gradually changed from a circular shape to a non-circular shape, such as a semicircular shape, an elliptical rectangular shape, or other polygonal shapes. Because the fluid is not very uniform due to centrifugal action after passing through the bent pipe, the flow state can be changed by changing the cross section of the outlet section, and the cyclone centrifugal separation of the gas-solid two-phase medium is better realized.
Preferably, the elbow 3 is of an integrally cast structure or a forged structure, and has a compact and stable structure and high strength. The bent pipe 3 and the main cylinder 1 are fixed by welding or flanges.
Preferably, the three side interfaces of the main cylinder 1 are respectively provided with a pipe joint 4, the axis of the pipe joint 4 is staggered with the radial direction of the main cylinder 1, the main cylinder 1 is connected with the elbow pipe 3 through different pipe joints 4, and the inner side wall of the pipe joint 4 is locally tangent to the inner side wall of the main cylinder 1. The pipe joint 4 and the main cylinder 1 are welded and fixed with each other. Smooth flowing of fluid media is guaranteed, and impact is reduced.
