Embodiment Construction

[0025] The present invention is mainly prepared by adding raw materials into a certain amount of water in a proportion and sequence, mixing and stirring at a certain temperature, reacting to a paste, and drying and pulverizing. It is made from the following raw materials by weight: 1-5% of mica powder, 1-5% of diatomaceous earth, 1-5% of hydrophobic silica, 5-10% of silicone oil, 1-5% of sodium silicate, Sodium hydroxide 5-10%, magnesium oxide 1-5%, metal zinc compound 70-80% and organic solvent 5-10%.

[0026] like figure 1 As shown, it is a graph of the experimental results of the reaction ability of the inert carrier and the active purification substance with hydrogen sulfide according to the embodiment of the present invention. The experimental steps are: weigh 5*10 -3 Kg of inert carrier and active purification substances are placed in a U-shaped tube, and an air pump is used to pass hydrogen sulfide gas through one end of the U-shaped tube at a rate of 0.05L / min. The o...

Abstract

The invention discloses a hydrogen sulfide gas leakage scavenger characterized by comprising the following components: an inert carrier, active purifying substances and an organic solvent. The inert carrier has a surface area of 30-1000 m<2> / g and can keep the thermal stability at 100-300 DEG C; and the active purifying substances are selected from simple substances, compounds and / or mixtures of sodium, aluminum, silicon, magnesium, zinc and carbon. When hydrogen sulfide is leaked, the hydrogen sulfide gas leakage scavenger can react with the hydrogen sulfide leaked in air, reduce and control the diffusion speed and the diffusion range of the hydrogen sulfide in a short time, thereby saving valuable time for surviving, rescuing and evacuating people in a diffusion area, in addition, the hydrogen sulfide gas leakage scavenger as solid powder has good dispersion, high scavenging speed and convenient use, effectively reacts with the hydrogen sulfide and lessens serious results caused by hydrogen sulfide leakage.

Description

technical field [0001] The invention relates to the technical field of chemical reagents for removing leaked toxic gas and avoiding casualties and property losses, in particular to a hydrogen sulfide gas leak scavenger. Background technique [0002] In my country's petrochemical industry, hydrogen sulfide poisoning is one of the main acute poisoning hazards in petrochemical enterprises. Fatal accidents caused by hydrogen sulfide poisoning occur frequently in the petrochemical industry. High-concentration hydrogen sulfide poisoning has a high mortality rate, and accidents are mostly sudden and group-based, so the harm is greater. [0003] When exploiting sour oil and gas fields, it will be accompanied by the production of hydrogen sulfide. Hydrogen sulfide is a nerve agent, which is a suffocating and irritating gas, mainly poisoning the central nervous system and respiratory system of people, so when it leaks, it is easy to cause a great threat to personnel.
