Abstract

The invention discloses a carbon dioxide hydrate reaction device and a method for improving the generation effect of the Carbon dioxide hydrate reaction device. The carbon dioxide hydrate reaction device is characterized by comprising an air supply system, a cooling system and a high-pressure reaction kettle, wherein the air supply system is connected with one side of the cooling system, and the other side of the cooling system is connected with the high-pressure reaction kettle; the air supply system comprises a carbon dioxide gas supply tank, an air compressor, a first conveying pipeline anda gas valve; and the cooling system comprises a low-temperature water domain cooling slot and a cooling tank. The method comprises the steps of regulating the temperature of a cooling liquid in the cooling tank to (-4)-(1) DEG C, keeping the temperature constant, introducing 300g of blended dry water into a reaction tank of the reaction kettle, exhausting carbon dioxide gas in the carbon dioxidegas supply tank into the reaction tank, maintaining the pressure in the reaction tank at 2.6MPa-3.5Mpa, and starting a stirring motor to drive spiral stirring blades to stir. The carbon dioxide hydrate reaction device has the advantages that the structure is simple, the reaction rate is increased, the induction time is shortened, and the efficiency is improved.

Description

technical field [0001] The invention relates to the field of hydrate technology, in particular to a carbon dioxide hydrate reaction device and a method for improving its generation effect. Background technique [0002] The modern industrial society has undergone long-term development. The industrialization of major countries in the world is highly developed, and the industrial level has made great progress. However, the entire industrial system is inseparable from the consumption of fossil fuels. The emission of exhaust gas has become the shadow of industrial development. A large amount of greenhouse gas carbon dioxide released after the combustion of these fossil fuels has the functions of heat absorption and heat insulation, thus causing global warming to become increasingly serious. my country is a big country that consumes electricity and oil, and its carbon dioxide emissions are increasing day by day. How to effectively separate and recover CO2 resources while accelerat...
