Embodiment Construction

[0019] Specific embodiments of the present invention will be described in detail below in conjunction with the technical solution and the drawings.

[0020] As shown in the figure, according to the described device structure connection, the method of using this device for co-production of carbon dioxide capture and seawater desalination is as follows:

[0021] (1) Gas-water transportation: seawater is introduced into the clarification tank 1, the water pump 3 pumps the seawater into the filter 12, and the gas in the gas source 2 is pressurized by the gas booster pump 4 to twice the equilibrium pressure of the carbon dioxide hydrate phase After left and right, together with seawater enter the tube heat exchanger 8 in the first stage for pre-cooling, the gas-liquid pressure before entering the tube heat exchanger is monitored by the pressure sensor 18, and the mixed gas and seawater pass through the tube heat exchanger outlet The valve 14 enters the hydrate formation reactor 9;

Abstract

The invention provides a carbon dioxide capturing and seawater desalting co-production device and method based on a hydrate method, belonging to the technical field of hydrate application. The carbon dioxide capturing and seawater desalting co-production device comprises a gas-water conveying part, a hydrate generation and decomposition control part and a product storing and discharging part. The hydrate generation and decomposition control part comprises a front-grade structure and a rear-grade structure; a hydrate generation condition is gas supersaturation. A first-grade hydrate generates residual gas and decomposed water to be used as second-grade raw materials; after two grades of treatment, fresh water is obtained and stored; N2 is discharged to atmosphere by a gas exhausting safety valve; carbon dioxide is introduced into a gas tank to be stored. The carbon dioxide capturing and seawater desalting co-production device is applicable to the co-production of carbon dioxide capturing and seawater desalting of a fossil fuel power station in a coastal region, so as to meet the requirements of the carbon dioxide capturing of a smoke CO2 / N2 power station; a heat exchanger is used for pre-cooling so that the cold loss is reduced and the energy utilization rate is improved; the reaction speed is increased by high-speed agitation in a hydrate generation process; emissions comprise the N2 and concentrated seawater and have no pollution to the environment.

Description

Technical field [0001] The invention belongs to the technical field of hydrate application, and relates to a carbon dioxide capture and seawater desalination co-production device and method based on a hydrate method. Background technique [0002] With the increasingly serious greenhouse effect, carbon dioxide capture and storage technology has received extensive attention; at the same time, due to the shortage of fresh water resources, seawater desalination technology has also been widely studied. Existing carbon dioxide capture technology and seawater desalination technology generally have the problem of high energy consumption, and the application of hydrate technology has certain potential in reducing energy consumption. The principle of CO2 capture technology based on the hydrate method is to separate the hydrate gas from the non-hydrate gas (N2, H2, etc.) by forming the hydrate component (CO2) in the mixed gas. Research has been carried out on the technology of seawater des...
