Problems solved by technology

Due to the need to achieve high-pressure sealing, the motor and screw generally use magnetic transmission. When the hydrate reaction device is enlarged, the magnetic transmission device is very heavy, and often requires high mechanical energy consumption, which increases additional energy consumption.

Abstract

The invention belongs to the technical field of hydrate reaction equipment, and in particular relates to a spray hydrate continuous reaction device, which adopts the spray hydrate reaction mode, and has a relatively large gas-liquid contact area between atomized small droplets and gas , can enhance mass transfer and significantly increase the hydration reaction rate. During the reaction process, with the help of the pressure difference between the high-pressure environment inside the reactor and the low-pressure environment outside the reactor, the small hydrate particles are continuously transported out of the reactor, realizing The continuous production of hydrates can avoid the problems of complex mechanical structure and high energy consumption of the traditional screw extrusion transportation method by means of pressure difference to transport small hydrate particles; its structure is simple, the principle is scientific and reliable, and it can The pressure difference between the high-pressure environment in the reactor and the low-pressure environment outside the reactor uses the function of the fluidized restrictor to continuously transport small hydrate particles from the reactor to the outside, as well as unreacted reaction liquid and unreacted materials that can be reused. reactive gas.

Description

Technical field: [0001] The invention belongs to the technical field of hydrate reaction equipment, in particular to a spray type hydrate continuous reaction device, which realizes the continuous production of hydrate. Background technique: [0002] Due to its excellent characteristics, natural gas has accounted for an increasing proportion of energy supply in recent years, and its development and promotion have been severely restricted due to its huge regional distribution differences and seasonal supply and demand imbalances. Although compressed natural gas, liquefied natural gas technology and long-distance gas transmission have played a huge role in the seasonal peak shaving and regional allocation of natural gas, the pressure and temperature conditions when using CNG and LNG technology for storage and transportation are very harsh. Issues such as pressure supplementation and pipeline maintenance should be considered. Based on this, researchers continue to explore and d...
