Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] The principle of the desulfurizing agent recovery device in the organic amine desulfurization process of the present invention is: after the sintering flue gas is treated with an organic amine desulfurizing agent (absorbent), the flue gas entraining the desulfurizing agent is treated with a supergravity rotating bed to capture water and recover desulfurization The recovery liquid is concentrated in the recovery tank, and circulated to capture the entrainment of the flue gas. When the concentration of the organic amine desulfurizer in the recovery liquid reaches 5%, it returns to the desulfuri...

Abstract

The invention discloses a desulfurizer recovery device for an organic amine desulfurization process and a desulfurizer recovery method utilizing the same. A supergravity revolving bed is communicated with a recovery tank; the recovery tank is communicated with a solution tank, a new water supply system is used for supplying new water to the supergravity revolving bed, and another pipeline is used for returning the solution in the recovery tank back to the supergravity revolving bed, and the solution tank is connected with a desulfurization system; an outlet for fume obtained by desulfuration of the desulfuration system is connected with the supergravity revolving bed; a padding of the supergravity revolving bed is divided into two parts, the upper padding part is an annular padding made of a polypropylene material, the lower padding part is a stainless steel deflector padding, and a three-blade fan is arranged between the two paddings. The device and the method are capable of efficiently recovering the desulfurizer, ensuring stable desulfurizer concentration and desulfuration effect of the desulfuration system, and greatly lowering the operation cost of the process.

Description

technical field [0001] The present invention relates to the recovery technology of desulfurizing agent components in sintering flue gas organic amine wet desulfurization system, and more specifically, the embodiment of the present invention relates to a desulfurizing agent recovery device and desulfurizing agent recycling method for organic amine desulfurization process. Background technique [0002] Existing sintering flue gas desulfurization mainly adopts wet flue gas desulfurization technology. After the desulfurization system is in operation, because the sintering flue gas is sprayed to cool down, washed or absorbed at 50°C to 60°C, the flue gas entrains about 12% to 14% after the absorption is completed. % of water, which contains a lot of desulfurizer (absorbent) components, which are recovered and captured through the recovery section or the trapping device, but there is still a large amount of desulfurizer that escapes with the flue gas entrainment, and it is estimate...
