Description

Stable supporting inlet and outlet pipe structure of spherical tank

Technical Field

The utility model belongs to the technical field of chemical industry equipment, in particular to stable supporting business turn over tubular construction of spherical tank is applicable to the stable bearing structure who stores the business turn over pipe of VCM medium spherical tank or is applied to other spherical tanks that store highly extremely harm the medium.

Background

In the vinyl chloride device, for the VCM spherical tank, the VCM medium characteristics are as follows: the material is extremely explosive, can form an explosive mixture when mixed with air, has the risk of combustion and explosion when meeting heat sources and open fire, has higher density than air, can be diffused to a far place at a lower place, and is determined to be a human carcinogen. The design of the inlet and outlet positions and the structure of the spherical tank not only ensures the realization of the process purpose, but also meets the requirements of safety and economy. In chemical production, similar extremely highly hazardous media are numerous, and for this type of media, VCM canisters are an example, being explored. The spherical tank is divided into an upper polar zone, an upper warm zone, an equatorial zone, a lower warm zone and a lower polar zone from top to bottom in sequence, the inlet and outlet positions of the spherical tank are generally arranged at the lower pole of the spherical tank, the lower pole is opened, the inlet and outlet forged piece pipes are integrally reinforced, and the outlet pipe is provided with a vortex breaker.

In order to solve the technical problems, in the existing spherical tank structure, a liquid inlet and a liquid outlet of the spherical tank are arranged at the upper pole, the liquid needs to be sent out from the top of the spherical tank, and as VCM is saturated liquid, the liquid cannot be pumped out from the spherical tank through a pump, and the material in the spherical tank can be sent out only by adopting a nitrogen pressurization mode or a compressor pressurization mode. The existing structure that the inlet and the outlet are arranged on the upper pole of the spherical tank is generally arranged as follows:

(1) the inlet and outlet are arranged on the upper pole and are not provided with the inward extending pipes. The mode adopts the upper pole of the spherical tank to be provided with the hole, and the inlet and the outlet are integrally reinforced by the forged piece pipe. For the inlet pipe, since the spherical tank is generally tens of meters high, the liquid directly impacts the bottom from the top of the tens of meters high, so that a large impact force is generated, and the liquid splashes, so that static electricity is generated, and the spherical tank is very dangerous for explosive media. For the outlet pipe, without the inner extension pipe, the liquid needs to be directly sucked from the spherical tank, which cannot be realized in the technical aspect.

(2) The inlet and the outlet are arranged on the upper pole, the outlet is provided with an inner straight pipe, and the bottom of the inner straight pipe is supported. As shown in figure 1, this kind of mode adopts the utmost point trompil on the spherical tank, the whole reinforcement of forging pipe is used to medium exit 2, the export is in forging pipe below welding inner extension pipe 3 and is linked to the spherical tank bottom, inner extension pipe bottom is fixed a position with the inner extension pipe supporting component 4 that the sleeve pipe adds the adjusting bolt, this problem of medium in the spherical tank taken out from the outlet pipe has been solved, but this kind of bearing structure is not very stable, to the spherical tank of major diameter, the pipe support is not arrived in very long partly inner extension, can arouse vibrations at the in-process that the medium flows out, outlet pipe stability has the problem.

(3) The inlet and the outlet are arranged on the upper pole, the outlet is provided with an inner extension pipe, and the whole section of the inner extension pipe is supported by the reinforcing rib. As shown in figure 2, in the mode, an upper pole of the spherical tank is provided with a hole, an inlet and an outlet are integrally reinforced by a forged pipe, an inner extension pipe 3 is welded below the forged pipe at the outlet, rib plates are added to the inner extension pipe every 2-3 meters, the rib plates are used as inner extension pipe supporting components 4, one end of each rib plate is welded on the inner extension pipe, the other end of each rib plate is welded on the inner wall of the spherical tank, the supporting distance is long, and the supporting stability is poor. In addition, in a large spherical tank, the material is very consumed, and the problem that the medium at the bottom of the tank cannot be discharged is also solved.
