In the grand industrial map of non-ferrous metal smelting, since its establishment, Yunnan Chihong Zinc and Germanium Co., Ltd. has been ranked among the 100 largest non-ferrous metal smelting enterprises in China by virtue of its excellent technical strength and steady development trend. Its production process from ore smelting to metal refining, each step embodies the wisdom and sweat of countless scientific researchers and industrial workers, and continuously transports valuable metal resources for the country's economic construction.

However, behind the glory of industrial production, there are many security challenges that are difficult to ignore. At the production site of Chihong zinc germanium in Yunnan, arsine, a colorless, highly toxic and garlic-smelling gas, threatens the lives of workers at all times. It quietly pervades the production space. Once the concentration exceeds the standard, the human body will quickly cause poisoning symptoms after inhalation. In mild cases, dizziness, fatigue, nausea, and even life-threatening due to respiratory failure and multiple organ function damage. For employees who have been fighting in the production line for a long time, every time they enter the work space, it seems that they are having 1 a thrilling game with death.

at this critical moment, yiyuntian, a high-tech enterprise focusing on the field of gas safety monitoring, brought its star product MIC-600-ASH3-A-TJ an online arsine detection alarm, illuminating the road to safety upgrading of Yunnan chihong zinc germanium co., ltd. Yiyuntian With profound technical accumulation, excellent product performance and considerate service concept, it has tailored a set of comprehensive and intelligent safety protection solutions for the non-ferrous metal smelting industry, which is industrial Production safety has injected new vitality and protection.

1, scheme background

Arsine Detector is a tool for detecting arsine gas. Arsenide is a highly toxic gas, which is a waste gas produced in some industrial processes.In occupational exposure to a variety of metals (such as zinc, tin, antimony, lead, copper, etc.) ore often contains arsenic sulfide. Arsenic ore in the smelting, processing, storage process in the case of acid (sulfuric acid, hydrochloric acid), wet can produce hydrogen arsenide. Therefore, it is possible to produce arsine gas in many chemical environments. Occupational acute arsine poisoning is a systemic disease mainly caused by acute intravascular hemolysis caused by inhaling high concentrations of arsine gas in a short period of time in occupational activities. In severe cases, acute renal failure may occur. Therefore, the defense of this gas leakage is particularly important!

Health Standard: The maximum allowable concentration of harmful gases, vapors and dust in the air of workshops issued by China in 1979 is 0.3mg/m3.

Yunnan chihong zinc germanium co., ltd. was established on July 18, 2000. it is one of the 100 largest non-ferrous metal smelting enterprises in China. during the production process, the arsine produced is highly toxic to human body. a fixed arsine detector is installed and the arsine concentration exceeds the standard, in order to protect the life safety of operators entering the space.
