A gas hydrate high-speed preparation method and device

Abstract

The invention discloses a high-speed preparation method and device of gas hydrate. First, the water and gas required for the hydration reaction are cooled and then enter the bubble generator. The gas is directly inhaled by the negative pressure generated when the water flows through the bubble generator, and the mixture of water and gas enters the tubular reactor to continuously obtain the generated hydrate. The device includes a gas source, a heat exchanger, a bubble generator, a tubular reactor, a cooling heat exchanger, a separation device, a connecting pipeline, a valve, and a water pump connected in sequence; the bubble generator is composed of an inner and outer tube, and the inner tube is connected through a constriction The outlet of the generator, the casing is sleeved outside the inner tube and communicated with the outlet of the generator; the tubular reactor is a tubular structure with spiral blades inside. The separation equipment is respectively connected with the gas inlet or the liquid inlet of the bubble generator to form a gas or liquid circulation loop. The invention avoids the use of a gas compressor, which not only greatly reduces the energy consumption of the hydrate generating system, but also makes the bubble size smaller and the size distribution more uniform.

Description

technical field [0001] The invention relates to a high-speed preparation method and device of gas hydrate. technical background [0002] Gas hydrate is an ice-state supramolecular cage formed by water and small molecular gases under high pressure and low temperature conditions. Different types of gases form different types of gas hydrates. 1 volume of gas hydrate can release 100~200 volumes The gas, that is to say, can compress its body by 100~200 times. Combining gas and water at the gas source to produce gas hydrate (solid like ice), transporting the solid gas hydrate to the gas destination, releasing the gas for domestic and production use, achieving the purpose of efficient and safe transportation. The application of this technology requires an efficient gas hydrate generation method and equipment. [0003] For example, natural gas hydrate (NGH) is a cage compound formed by water and natural gas under low temperature and high pressure conditions. Under the condition o...
