System device for lawfully gathering and separating CO2/CH4/N2 by using phase change ionic liquid water

Abstract

The invention relates to a system device for lawfully gathering and separating CO2 / CH4 / N2 by using phase change ionic liquid water, which can effectively solve the problems of lawfully gathering and separating CO2 / CH4 / N2 by using phase change ionic liquid water and air pollution and energy loss from industry waste gas discharge. The structure comprises a first reaction kettle and a second reactionkettle, a clamp sleeve is arranged on the outer wall of each reaction kettle, a heat insulation layer is arranged outside each clamp sleeve, a pressure gauge, a temperature sensor and a gas detectorwhich are communicated with the inside of the reaction kettles are arranged on the reaction kettles, a stirrer is arranged in each reaction kettle, the stirrer passes through a stirring rod which extends out of the upper part of the reaction kettle and is connected with the rotating shaft of the motor to form a stirring structure in the reaction kettle; an air inlet pipeline is communicated with the reaction kettle, an air outlet pipeline connected with the reaction kettle is communicated with the reaction kettle through a flow control instrument, a gas storage tank is arranged on the pipelinebetween the first reaction kettle and the second flow control instrument, the gas storage tank is communicated with the corresponding kettle, The system device is suitable for the absorption and separation of mixed gas, and can monitor the air pressure change in the gas hydrate formation process in real time.

Description

technical field [0001] The invention relates to chemical equipment, especially for capturing and separating CO 2 、CH 4 and N 2 A phase change ionic liquid hydration method to capture and separate CO by promoting the formation of gas hydrate 2 / CH 4 / N 2 system device. Background technique: [0002] According to statistics, the global average temperature increased by 0.6°C in the 20th century. If measures are not taken to limit CO 2 、CH 4 The global temperature will rise by 2~5℃ in the 21st century. As the largest developing country, our country bears the inescapable responsibility for the increasingly serious problem of greenhouse effect. According to the statistical survey of the International Energy Agency, my country's current CO 2 Emissions are second only to the United States, accounting for 1 / 7 of the world's total emissions. [0003] The gas emitted from the natural gas industry, mine mining and energy utilization usually contains a large amount of CO 2 and...
