Problems solved by technology

However, wet desulfurization has a high load and low desulfurization precision, and is not suitable for fine desulfurization of gases; biological and decomposition methods have complicated operating conditions and high costs, and cannot be widely used at present; dry desulfurizers used in China are mainly based on oxidation Mainly iron, zinc oxide and activated carbon
However, due to the limitation of chemical balance, conventional iron oxide desulfurizers are difficult to achieve fine desulfurization, and are affected by entrained water vapor, thereby reducing the effect
Although zinc oxide can desulfurize finely, it needs high temperature and is expensive

Embodiment 1

[0029] A preparation method of iron-based anti-virus deodorizing desulfurizer:

[0030] A, choosing iron content is 70% low-carbon iron and steel material, and this iron and steel material is pulverized into 100~200 mesh fine powders with pulverizer;

[0031] B, the fine powder in step A is processed under the condition that power is 5.5 watts through magnetic separator to make its iron content reach 90%, carbon content is the iron powder of 0.2%;

[0032] C. Add isocyanate to the iron powder in step B at a temperature of 1500°C. When it enters the foaming stage, integrate nano attapulgite. After reacting for 15 minutes, add dimethyl silicone oil, stir for 15 minutes, cool to room temperature, and then add oxalic acid , stirred and reacted for 10 minutes, and then crushed to 120 mesh particles by a pulverizer;

[0033] D. React the particles in step C at 500°C for 2 hours in a heating furnace containing carbon monoxide gas flow, and cool to room temperature to obtain polariza...

Abstract

The invention relates to an iron-based antiviral deodorant desulfurizer and a preparation method thereof. The iron-based antiviral deodorant desulfurizer is prepared from the following components in parts by weight: 100-300 parts of low-carbon iron powder with the content of carbon of 0.2%-0.5%, 3-10 parts of isocyanate, 5-10 parts of nano-attapulgite, 0.5-1.5 parts of simethicone, 3-5 parts of oxalic acid, 10-20 parts of 1% sodium carbonate and 80-150 parts of ordinary activated carbon particles. The iron-based antiviral deodorant desulfurizer provided by the invention has the advantages of being recyclable, large in specific surface area, free of pollution, high in reaction speed and low in operation cost.

Description

technical field [0001] The invention belongs to the technical field of hydrogen sulfide desulfurization, and in particular relates to an iron-based anti-toxic, deodorizing and desulfurizing agent and a preparation method thereof. Background technique [0002] All sulfur-containing compounds have the possibility of generating hydrogen sulfide through various reactions. The hydrogen sulfide in industrial waste gas mainly comes from oil refineries, natural gas purification plants, gas purification plants, smelters, tanneries, nitrogen fertilizer plants, and pesticide plants. etc., but in terms of quantity, it is dominated by oil refineries, natural gas purification plants, coal gas purification plants and synthetic nitrogen fertilizer feedstock gas. h 2 S is a harmful impurity in industrial gases such as natural gas, coke oven gas, and semi-water gas. Its existence will not only cause equipment and pipeline corrosion, catalyst poisoning, but also a foul-smelling gas with the s...
