Embodiment 1

[0020] First, put 100g of spherical desulfurizer whose active components are ferric oxide and ferric oxide, organic binders are kale powder and cellulose powder in a beaker, add about 300ml of water to it, at 25°C After soaking for 2 hours, filter to remove the water therein, and then cure the wet bulb under natural conditions for 20 hours. Finally, the spherical desulfurizer was dried at 90° C. for 1.5 hours to prepare a high-strength spherical desulfurizer A.

[0021] The spherical desulfurizer described in this example is the JX-1A spherical desulfurizer produced by Beijing Sanju Environmental Protection New Materials Co., Ltd.

Embodiment 2

[0023] First, put 100g of spherical desulfurizer whose active component is amorphous ferric oxyhydroxide and organic binder is methyl cellulose sodium into a beaker, add about 300ml of water to it, soak at 15°C for 12h, and filter Remove the moisture therein, and then cure the wet bulb under natural conditions for 32 hours. Finally, the spherical desulfurizer was dried at 90° C. for 1.5 hours to prepare high-strength spherical desulfurizer B.

[0024] The spherical desulfurizer described in this example is SDS-100 spherical desulfurizer produced by Beijing Sanju Environmental Protection New Materials Co., Ltd.

Embodiment 3

[0026] First, put 100g of spherical desulfurizer whose active component is amorphous ferric oxyhydroxide and organic binder is cellulose powder into a beaker, add about 300ml of water to it, soak at 10°C for 18h, and filter to remove the Moisture, and then the wet bulb is cured under natural conditions for 24 hours. Finally, the spherical desulfurizer was dried at 110° C. for 1 hour to prepare a high-strength spherical desulfurizer C.

Abstract

The invention provides a method for enhancing strength of a ball-type desulfurizer, and belongs to the technical field of desulfuration purification. Specifically, the method comprises the following steps of (1) immersing the ball-type desulfurizer in water for some time, leaching out the desulfurizer, placing the desulfurizer under a natural condition for curing; and (2) drying the ball-type desulfurizer obtained by the step (1) at a certain temperature to obtain the ball-type desulfurizer with high strength. The ball-type desulfurizer prepared by the method has point particle strength reaching as high as 50 N without reducing a desulfuration effect.

Description

technical field [0001] The invention relates to a treatment method for a desulfurizing agent, in particular to a method for increasing the strength of a spherical desulfurizing agent, and belongs to the technical field of desulfurization and purification. Background technique [0002] Sulfides are produced in many occasions of industrial production. For example, in the production process of producing chemical raw materials from coal or petroleum, as well as in the wastewater or waste gas discharged from general industrial production. Among them, in the production process of producing chemical raw materials from coal or petroleum, hydrogen sulfide will be produced. The production of hydrogen sulfide is mainly due to the presence of more sulfur-containing substances in the raw materials. This part of sulfur-containing substances will occur during the above-mentioned production process. The presence of hydrogen sulfide released by the reaction will directly lead to the poisoni...
