Hydrate pellet continuously processing device

Abstract

The invention relates to a hydrate pellet continuously processing device. The hydrate pellet continuously processing device is composed of three functional units including, a, a pelleting unit, b, a sorting unit and c, a copious cooling unit, wherein the pelleting unit produces hydrate pellets, reduces the possibility of collision and breakage when the pellets fall off and improves the pelleting efficiency; the sorting unit sorts the semi-finished hydrate pellets to ensure regular shape and appropriate size of the hydrate pellets; the copious cooling unit performs copious cooling operation with a small amount water stuck on the surfaces of the hydrate pellets during pelleting to coagulate the water to a layer of protective casing on the surface of every pellet and accordingly to increase the strength of the hydrate pellets, and the protective casing can retard decomposition of the hydrate pellets to some extent. By means of the three units above which are independent and applicable tocontinuous operation, the hydrate pellet continuously processing device achieve continuous processing and production of the hydrate pellets and enables the produced hydrate pellets to have certain strength and adapt to complex and severe transport environments.

Description

technical field [0001] The invention relates to the technical field of natural gas hydrate application, in particular to a continuous processing device for hydrate balls. Background technique [0002] Natural gas hydrate is a clathrate complex formed by gas molecules under certain temperature and pressure conditions. The water molecules are combined by hydrogen bonds to form the main lattice, while the gas molecules are fixed in the lattice gaps formed by the water molecules under the action of van der Waals force. Due to its high gas storage capacity and excellent physical and chemical properties, gas hydrate has long been considered by researchers as an excellent way to transport natural gas. The method of transporting natural gas with hydrate technology is called NGH technology. Compared with compressed natural gas (CNG) and liquefied natural gas (LNG), this technology has lower pressure and temperature requirements, which greatly increases the safety and security of tra...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing pelletizing machines are suitable for steel, non-ferrous metallurgy, cement, fertilizer and other industrial fields. Due to the special properties of hydrate pellets, traditional pelletizing machines cannot be directly applied to the NGH industry.

At the same time, after a simple modification of the traditional pelletizing machine, it is directly used in the production process of hydrate pellets, which will bring great safety hazards, and will also lead to limited strength of the produced hydrate pellets, which cannot cope with the complex transportation environment.
