Embodiment 1

[0028] In order to improve the sediment separation efficiency in the process of natural gas hydrate exploitation, reduce the loss of natural gas hydrate and avoid the formation of air resistance in the separator by natural gas, this embodiment discloses a sediment cyclone separator for natural gas hydrate exploitation, specifically Organization see Figure 1-5 , the body of the cyclone separator includes a cylindrical shell 3 above and a conical shell 5 below, wherein the cylindrical shell is 285 mm high, the shell diameter is 250 mm, the conical shell is 463 mm high, and the cone angle is 15°. An overflow port 1 is provided on the top of the cylinder body 3, and a feed port 2 is provided on the side wall. The diameter of the overflow port is 70 mm, and the total length of the overflow pipe is 85 mm. is 65 mm, the diameter of the feed inlet is 40 mm, and the length is 50 mm; at the bottom of the conical cylinder 5, there is an underflow opening 9, and the diameter of the under...

Embodiment 2

[0035] In order to illustrate the impact of the flow hole on the link in the sediment cyclone separator for natural gas hydrate exploitation disclosed in Example 1 on the change in resistance, this embodiment did separator pressure drop experiments at different flow rates. The result is as Image 6 As shown, it can be seen from the figure that within the given flow range, the pressure drop of the separator without flow holes on the link is about 9.5% higher than that of the separator with flow holes.

Abstract

The invention discloses a sediment cyclone separator for natural gas hydrate mining. The separator body includes a cylindrical cylinder and a conical cylinder. An overflow port is provided on the top of the cylindrical cylinder and a feed port is provided on the side wall. There is an underflow port at the bottom of the conical cylinder, and a bond is arranged longitudinally inside the separator body and at the center of the separator axis. The top of the bond is fixedly connected to the cylindrical cylinder through the upper fixing bracket of the tie, and the bottom end of the tie is fixed through the lower fixing bracket of the tie. It is fixedly connected with the tapered cylinder. The separator has simple structure, convenient installation, low processing cost, wide application range and high separation efficiency, and is suitable for sediment separation in the process of natural gas hydrate exploitation; the built-in link enhances the strength of internal swirl flow and helps to achieve secondary separation; The flow stability in the inner swirl area is improved, which is conducive to the safe operation of the system; the ties move the zero-velocity envelope outward, which is beneficial to reduce the loss of hydrate; the flow hole provides a channel for the central gas to float up, avoiding the gas resistance caused by operation failure.

Description

technical field [0001] The invention belongs to the technical field of separation of mixtures in the exploitation process of seabed natural gas hydrate, and in particular relates to a sediment separation device for fluidized exploitation of seabed natural gas hydrate, and can also be used for purification and separation of complex flow systems of other pipelines. Background technique [0002] As a new type of clean energy, natural gas hydrate is abundant in polar permafrost, marine sediments, and land-sea borders. Under the same conditions, the carbon content of the same volume of natural gas hydrate is much higher than that of other fossil energy sources. Therefore, natural gas hydrate, as a new type of clean energy that can replace fossil energy in the future, has attracted attention from all over the world. [0003] However, due to the unique occurrence conditions of natural gas hydrate and its own physical characteristics, the production process of natural gas hydrate is...
