Frozen food processing plants almost invariably utilize ammonia-based refrigeration systems. Wherever ammonia is present, there is essentially a "ticking time bomb." To mitigate this risk, a

Due to the high water content of the sludge after the sludge thickening process in the sewage treatment plant, it is still in a fluid state. Therefore, sludge dewatering and dry chemical process treat

In warehouses where baijiu, huangjiu, and fruit wine are produced, alcohol (ethanol) is highly volatile. Ethanol vapor is a Class A flammable and explosive gas. When the gas reaches the lower explosiv

In the wastewater treatment industry, disinfection is a critical step in ensuring effluent quality meets standards. Chlorine gas (Cl₂) has long been one of the most widely used disinfectants in water

Chlorine gas (Cl₂) is a toxic, yellow-green gas with a strong, pungent odor. Accurately detecting the presence of chlorine gas is crucial in chemical laboratories and industrial settings to ensure per

As a clean and efficient energy source, fuel gas (primarily natural gas) is widely used in sectors such as residential living, industrial production, power generation, and transportation. Its main com

Mine environments are complex and entail high potential risks; miners are frequently exposed to various hazardous gases. These gases not only threaten their health but can also trigger serious safety

Gas detectors are critical equipment for ensuring the safety of personnel during operations; improper use can lead to misinterpretation or even hazardous situations. The following are key consideratio

LEL (Lower Explosive Limit) refers to the Lower Explosive Limit concentration of the gas. A 20%LEL indicates that the concentration of flammable gas in the environment has reached 20% of its lower exp

The fire alarm system comprises triggering devices-such as smoke detectors, heat detectors, flame detectors, and combustible EX gas detector -as well as a fire alarm control panel, which is used to re

To select an appropriate calibration gas cylinder for gas detector, you must determine the type of gas, its concentration, and the cylinder material. 1.Select the cylinder body material based on the c

First, during the coking process, coal is heated to temperatures exceeding 1000℃, triggering reactions that generate toxic gases: carbon monoxide (CO) and hydrogen (H₂). Hydrogen sulfide (H₂S) is form
