The hazardous chemicals industry is flammable, explosive, toxic, harmful and corrosive, and is "ubiquitous" in the field of chemical production, operation and storage.
A large hydrogen sulfide poisoning accident occurred in the hydrolysis acidification tank of the sewage treatment station of a battery *** phase II industrial park in Huizhou, resulting in 3 deaths, 1 injury, and a total economic loss of more than 3200 million. The hazardous chemicals industry is flammable, explosive, toxic, harmful and corrosive, and is "ubiquitous" in the field of chemical production, operation and storage.
A listed pump company in Hefei purchased the chassis of the Yuhesen explosion-proof inspection robot, combined with its own intelligent identification system to deliver a supporting oil Yulin gas gathering station, and checked in advance the leakage of trace hydrogen sulfide from the damage of the No. 2 pipeline connecting pipe of the reactor furnace of the gas gathering station, avoiding the poisoning accident of 4 inspectors. It reduces the hidden dangers and fault points of safety accidents at a petroleum Yulin gas gathering station, optimizes the workflow and risk control mode, strengthens safety supervision and management, and conducts real-time inspections on on-site operations by adopting an 8-hour duty system and a "4-hour full patrol" method, breaking the traditional way of on-site inspection by safety management personnel. It reduces the intensity and risk of on-site work. Reduce the annual safety incident rate from 5% to 02% 。
1) Production and manufacturing of sulfur-containing compounds in the chemical industry, such as parathion, ethion, dimethoate, sulfonamides, etc.; Hydrogen sulfide can be produced in petrochemical industry, coal chemical industry, natural gas chemical industry, rubber vulcanization process, etc.
2) Petroleum exploitation In the process of drilling and extracting oil, a large amount of hydrogen sulfide can often be ejected due to the impurity sulfur contained in the oil.
3) Sodium sulfide is used to remove hair when tanning and monosodium glutamate tanning leather, and sodium sulfide is used to remove iron from monosodium glutamate, which can produce hydrogen sulfide.
4) In some production processes of papermaking, sugar and food processing industries that use animals and plants as raw materials, hydrogen sulfide can be produced due to the fermentation and corruption of organic matter.
5) Mining and smelting industry All kinds of ores contain impurity sulfur, and a large amount of hydrogen sulfide can be produced in the process of mining and smelting; Hydrogen sulfide is used to purify certain metals to produce their insoluble sulfides, which are also produced.
6) Fishing industry Hydrogen sulfide can be produced after the fish in the fish tank rots, which can easily lead to poisoning when the ventilation is poor.
7) Sewage pipelines and underground operations Cleaning pickling ponds, sewers, sewage ditches, septic tanks, and garbage dumps can often be exposed to high concentrations of hydrogen sulfide.
8) Chemical cleaning operations, cleaning operations using sulfur-containing cleaning agents; Devices, containers, pipelines, heat exchangers, etc., whose materials and scales contain sulfur and sulfur compounds, will produce hydrogen sulfide gas under certain conditions.
9) In the development and purification of high-sulfur oil and gas fields, most of the units of oil refineries, cracking and benzene production units of chemical plants, improper discharge of waste gas and waste liquid containing hydrogen sulfide, as well as sewage treatment, laboratory analysis, inspection and maintenance and other operations may be exposed to hydrogen sulfide. Hydrogen sulfide is soluble in water and oil, and can be carried away from the source of occurrence with water or oil, causing accidental poisoning accidents. Hydrogen sulfide is mainly inhaled through the respiratory tract and infects the respiratory system and eyes.
Hydrogen sulfide with the molecular formula H2S and a molecular weight of 34076, under standard conditions, is a flammable acid gas, colorless, smells of rotten eggs at low concentrations, and is toxic. Its aqueous solution is hydrosulfuric acid. The molecular weight is 3408, vapor pressure is 20265kpa/25.5, the flash point is.
Hydrogen sulfide can directly interfere with the body's oxygen uptake and transport. As a result, intracellular respiratory enzymes lose their activity, resulting in cell hypoxia suffocation and death, hydrogen sulfide is very toxic, and the absolute lethal concentration of humans is 1000mg m. When the concentration of hydrogen sulfide in the air is 10 15 ppm, people have symptoms of poisoning, and the maximum allowable concentration of hydrogen sulfide in the workplace in our country is 10 mg m (about 67ppm）。
In the hazardous chemicals industry,In particular, regular patrols and inspections are important to ensure that gas leakage caused by aging pipelines and facilities causes widespread hazards. However, for humans, these tasks can pose serious risks. In order to solve this problem, explosion-proof patrol robots came into being.
