In which areas is the gas alarm applied?

Industrial and commercial applications

Regarding the hotel, restaurant, hotel kitchen, according to the "Safety Law of the People's Republic of China" and other relevant laws and regulations: All production, storage and use of flammable and violent items must be in accordance with the "Code for Design of Building Fire Protection", 10.3.2. Article "A Classy workshop and place where flammable gas and flammable steam are distributed shall be provided with a flammable gas concentration leak detection alarm device", and a flammable gas detection alarm device shall be installed reasonably; the gas, gas or artificial gas used in the kitchen of the hotel is flammable , explosive gas, and restaurant restaurant staff gathered more, is the key place to monitor fire and explosion accidents, so the installation of flammable gas alarm is a must.

Mainly produces gases: methane, carbon monoxide, hydrogen, liquefied gas.

Iron and steel smelting

The steel industry is an industrial industry mainly engaged in industrial production activities such as ferrous metal mineral mining and ferrous metal smelting processing, including mineral extraction and selection of metal iron, chromium and manganese, iron making, steel making and steel processing. The iron and steel smelting industry, steel wire and its products industry and other sub-sectors are one of the important raw material industries in the country. Metallurgical steel enterprises will produce a large number of by-products "gas" in the smelting production process (ie: coke oven gas, blast furnace gas, Converter gas), while gas is the best secondary energy source for steel companies. In order to make full use of secondary energy, gas is cleaned, transported, stored, pressurized and used. There are a large number of gas equipment and facilities. In order to make these gas equipment and facilities operate safely, operators and maintenance personnel will be exposed to carbon monoxide. Due to the lack of awareness of some people's lack of awareness of gas hazards (carbon monoxide and flammable gas), gas poisoning or explosion accidents may occur. Therefore, the safety protection test of metallurgical enterprises is very necessary.

Mainly producing gases: (CO) carbon monoxide, (CH4) methane, (H2) hydrogen, (H2S) hydrogen sulfide, (C6H6) benzene, (HN3) ammonia, (CS2) carbon disulfide, (C10H8) naphthalene, phenol, (02 Oxygen, (CO2) carbon dioxide gas, (N2) nitrogen gas.

Power Industry

Gas detection instruments have a wide market space in the power industry and can detect sulfur hexafluoride gas produced by power substations.

Mainly produces gases: ammonia, chlorine, hydrogen sulfide, sulfur hexafluoride, oxygen.

Polysilicon industry

The production process of polycrystalline silicon is mainly composed of high-purity quartz (reduced by high-temperature coke)→ industrial silicon (pickling)→ silicon powder (plus HCL)→SiHCL3 (by crude distillation)→ high-purity SiHCL3 (and hydrogen-reactive CVD process) →High purity polysilicon.

Coal industry

Coking industry, coal gasification-synthesis ammonia, coal-based methanol, coal-based synthetic oil, coal chemical co-production have a wide range of requirements for gas alarm products, especially for gas detectors such as sulfur dioxide, hydrogen sulfide, carbon monoxide, chlorine, ammonia, etc. The amount is very large.

Mainly produces gases: carbon monoxide, hydrogen sulfide, methane, sulfur dioxide, chlorine, ammonia.

Chlor-alkali industry

The production process of chlor-alkali enterprises will produce toxic, harmful, flammable gas leaks and even explosion accidents, ensuring that safe production is vital to the survival of enterprises. The hydrochloric acid process generally includes: hydrogen, chlorine→synthesis→cooling→absorption→hydrochloric acid. The process of caustic soda generally includes: raw salt→salt→filtration→neutralization→ion membrane electrolysis→caustic soda. Mainly produced gases: chlorine, hydrogen, vinyl chloride monomer, acetylene, ammonia and other toxic, flammable gases?

Fine Chemicals

Fine chemicals are closely related to people's daily life. It is as important as food production status and related to national security. Therefore, fine chemicals are one of China's pillar industries. At the beginning of the new century, fine chemicals were adopted by the State Economic and Trade Commission. It is included in one of the development priorities and guarantees safe production as the top priority of the fine chemical industry.

Mainly produced gas: concentration of combustible gas, ammonia gas, chlorine gas, methanol, acetone.

Aluminum industry

At present, all the world's aluminum is produced by electrolyzing cryolite-alumina melt. The flue gas emitted during the aluminum electrolysis process has gaseous and solid matter. The gas liberated by normal electricity is a mixture of carbon monoxide and carbon dioxide and a small amount of fluoride gas. .

Mainly producing gases: natural gas, chlorine, hydrogen, carbon monoxide, carbon dioxide

Biogas pool

The construction of biogas digesters in various places not only improved the rural health, reduced the burden on farmers, and protected the ecology. Some of them also formed an ecological agriculture system combining farming and breeding, which was widely welcomed by farmers, but the PH value of biogas digesters was 6.8- 7.5, the biogas content produced is also required to be tested.

Main tests: methane, carbon dioxide, pH.

Air quality control

With the increasing awareness of safety and health, people are increasingly pressing the air quality in the underground garage, rail transit and other spaces or the automatic air conditioning of the central air conditioner. In the areas of municipal pipe network, sewage treatment, urban pipe network, etc., municipalities need to use chlorine gas, hydrogen sulfide and other gases to detect tap water treatment and sewage treatment.
