Abstract

The invention belongs to the technical field of hydrogen sulfide treatment, and particularly discloses an efficient desulfurizing agent with an indication function and a preparation method thereof. The desulfurizing agent comprises the following components, by weight: 10-60 parts of an alkaline compound, 20-50 parts of basic cupric carbonate, 10-30 parts of nano powder and 0-25 parts of a surfacemodifier; the alkaline compound does not comprise basic cupric carbonate. And/or the desulfurizing agent comprises the following components, by weight: 30-110 parts of basic cupric carbonate, 10-30 parts of nano powder, 0-25 parts of surface modifier, 5-10 parts of activated carbon, 5-10 parts of a diatomite, 2-8 parts of a hydrophobic agent and 2-10 parts of a dispersing agent. According to the efficient desulfurizing agent with an indication function, desulfurizing agent powder with a large specific surface area is prepared by adopting a nanotechnology, so that the desulfurizing agent powderreacts with hydrogen sulfide more thoroughly, the absorption efficiency is higher; the final dosage of the desulfurizing agent can be controlled by adding an indicator, the dosage is controllable, and a problem that whether hydrogen sulfide is thoroughly removed cannot be judged is solved.

Description

technical field [0001] The invention relates to the technical field of hydrogen sulfide treatment, in particular to a high-efficiency desulfurizer with indicating function and a preparation method thereof. Background technique [0002] Hydrogen sulfide (H 2 S) is a highly toxic, colorless and transparent gas, heavier than air. Low concentration of hydrogen sulfide has a smell similar to rotten eggs; when the concentration is high, the olfactory nerve is quickly paralyzed, odorless, difficult to detect, inhaling a small amount of high Concentrations of hydrogen sulfide can be fatal in a short time. When the content of hydrogen sulfide in the air exceeds 1.5 ppm, it can cause death. Hydrogen sulfide is commonly found in mining, metal smelting, sulfur-containing oil and gas extraction, refining, rubber, leather and other industries. The death rate of hydrogen sulfide poisoning is high, and the accidents are often sudden and mass. Once a leakage accident occurs, it will serio...
