Embodiment 1

[0112] Figure 4 Example 1 is shown in . As for the honeycomb rotor 12, the 30g / m 2 Coating the coating solution mixed with solid amine particles with a particle size distribution of 0.02 to 0.1 mm and a heat-resistant and water-resistant binder on porous paper, and corrugating the dried sheet (photo 2) to a pitch of 3.0 mm and a height of 2.0mm, and it is wound and rotorized to obtain a volume specific gravity of 150kg / m containing 50% by weight of solid amine particles 3 The honeycomb rotor 12. In the present invention, since steam is used to desorb the adsorbed carbon dioxide, it is not necessary to make the honeycomb rotor 12 flame-resistant. However, in order to ensure shape retention and strength in hot water, it is preferable to mix inorganic fibers such as paper glass fibers or PET. Paper made of synthetic fibers such as , etc. is used as a support body, but if it is a non-woven fabric of synthetic fibers having steam resistance, shape retention, and strength, it is...

Embodiment 2

[0119] Figure 5 Example 2 is shown in . On the front and back of the sheet of aluminum foil 25μ, coat heat-resistant, water-resistant epoxy adhesive, use the sheet that is distributed and bonded with 0.3-1.2mm granular amine-based weak base ion-exchange resin particles ( Figure 14 ) corrugated into a pitch of 9mm and a height of 5.6mm, and further coiled or stacked to obtain a load of 240g / m 3 Carbon dioxide enrichment honeycomb rotor 12 of amine-based weak base ion exchange resin.

[0120] The sheet in which the ion exchange resin is distributed and bonded can be produced, for example, by a method such as Japanese Patent Publication Hei 7-16576, but it is not limited to this method.

[0121] The carbon dioxide recovery and concentration device returns to the adsorption area 13 through the adsorption area 13 and the desorption area 14 along the rotation direction of the honeycomb rotor 12 . When the material gas containing carbon dioxide gas, which is pre-treated to cool ...

Embodiment 3

[0127] Figure 6-a , b, c show the embodiment 3 of the situation where a water curtain purification zone is provided. in addition, Figure 6-b for Figure 6-a The A-A cross-section of the view, Figure 6-c for Figure 6-a The direction view in the B-B section of . For the front and rear boundaries of the adsorption area and the desorption area, the settings are as follows Figure 6-a The advantages of the situation of the water injection curtain raw material gas purification zone 15 and the water injection curtain carbon dioxide purification zone 16 shown in , b and c will be described. At the position where the rotor honeycomb moves from the adsorption area to the desorption area, the raw material gas in the void of the honeycomb is brought into the desorption area to reduce the recovery concentration of carbon dioxide. Moreover, at the position where the rotor honeycomb moves from the desorption area to the adsorption area, the high-concentration carbon dioxide gas in ...

Abstract

The present invention relates to a high-durability temperature swing adsorption carbon dioxide recovery and concentration device. In the honeycomb rotor recovery and concentration device for recovering carbon dioxide gas from flue gas, etc., the recovery is performed at a high recovery rate and the concentration is as high as possible. It can be miniaturized, can utilize low-temperature waste heat below 100°C, and can reduce the energy used for recovery and concentration. The honeycomb rotor carrying the adsorption material (solid amine, etc.) particles having the adsorption capacity of carbon dioxide gas is rotated in the casing that is at least divided into the adsorption area and the desorption area, and the honeycomb in the adsorption area is wetted, and the carbon dioxide containing The raw material is in contact with the raw material, while evaporating the cooling water, absorbing carbon dioxide gas, and moving the honeycomb with carbon dioxide gas to the desorption area by rotating, and desorbing high-concentration carbon dioxide gas by contacting with low-pressure steam, so as to achieve high recovery rate and high Concentration of carbon dioxide gas is recovered continuously.

Description

technical field [0001] The invention relates to a temperature swing adsorption carbon dioxide recovery and concentration device, which recovers with a high recovery rate, can be concentrated to a high concentration, can be miniaturized, has high durability, can utilize waste heat below 100° C., and consumes less energy. Background technique [0002] As a response to global warming, the world is trying to reduce carbon dioxide emissions from industry, cars and homes as much as possible. For this reason, efforts are being made to improve energy-consuming equipment into energy-saving equipment and to replace old equipment. In addition, as equipment for generating energy such as power generation, use equipment using renewable energy such as sunlight or wind power, or improve the power generation efficiency of thermal power plants, and develop the recovery of carbon dioxide discharged from thermal power plants in the future. Concentrated to store in the ground or deep sea techno...
