The main gas produced: methane, carbon monoxide, hydrogen, liquefied gas.
1. Biogas pool
The construction of biogas digesters in various places not only improves the sanitation of rural areas, but also reduces the burden on farmers, protects the ecology, and is generally welcomed by farmers. However, the PH value of the fermentation materials in biogas digesters is required to be 6.8~7.5, and the content of biogas produced also needs to be tested.
Main detection: methane, carbon dioxide, PH value.
2. Air quality control
With the enhancement of safety and health awareness, people are more and more urgent to control the air quality of underground garages, rail transit and other spaces or the automatic ventilation of central air conditioners. In the fields of municipal pipe network, sewage treatment, urban pipe network, etc., the municipal government needs to use gas detectors to detect chlorine, hydrogen sulfide and other gases in tap water treatment and sewer sewage treatment.
3. Steel smelting
The iron and steel industry is one of the important raw material industries in the country, but a large amount of by-product "gas" (ie: coke oven gas, blast furnace gas, converter gas) will be produced in the smelting and production process. Combustible gas), ineffective prevention, resulting in gas poisoning or explosion accidents. Therefore, it is very necessary for the metallurgical industry to install gas detectors to detect gas concentrations.
The main gases produced are: carbon monoxide (CO), methane (CH4), hydrogen (H2), hydrogen sulfide (H2S), benzene (C6H6), ammonia (NH3), carbon disulfide (CS2), oxygen (O2), carbon dioxide ( CO2), nitrogen (N2), naphthalene (C10H8), phenol, etc.
Fourth, the power industry
The power industry involves many fields and has a wide market space. It can detect sulfur hexafluoride gas generated by power substations.
The main gases produced are: ammonia, chlorine, hydrogen sulfide, sulfur hexafluoride, oxygen, combustible gas, hydrogen, carbon monoxide, sulfur dioxide, nitrogen oxides, etc.
5. Polysilicon Industry
The production process of polysilicon is mainly composed of high-purity quartz (reduced by high-temperature coke) - industrial silicon (pickling) - silicon powder (adding HCL - SiHCL3 (through crude distillation and rectification) - high-purity SiHCL3 (with hydrogen reaction CVD) process) - high-purity polysilicon.
6. Coal Industry
Coking industry, coal gasification, synthetic ammonia, coal-based methanol, coal-based synthetic oil, and coal chemical co-production all have extensive demand for gas alarms, especially for sulfur dioxide, hydrogen sulfide, carbon monoxide, chlorine, ammonia and other gas detectors. Very big.
The main gas produced: carbon monoxide, hydrogen sulfide, methane, sulfur dioxide, chlorine, ammonia.
In addition, the chlor-alkali industry, fine chemicals, aluminum industry, agricultural greenhouses, food cold storage, urban automobile exhaust and other fields all need to detect gas, and all need to install gas detection alarms.
