Escopo e aplicabilidade

This standard specifies the safety technical requirements for purification equipment of coating organic waste gas and describes the verification methods. It is applicable to the design, manufacturing, installation, acceptance, operation, and maintenance of such purification equipment. The standard covers various types of equipment including activated carbon adsorption, zeolite adsorption, zeolite rotor wheel, thermal oxidation (TO), catalytic oxidation (CO), regenerative thermal oxidation (RTO), regenerative catalytic oxidation (RCO), and liquid absorption devices. It replaces the previous version GB 20101-2006 and introduces new requirements for control systems and specific purification technologies.

Requisitos técnicos

The standard outlines comprehensive safety requirements across several key areas. General Requirements mandate pre-treatment devices to remove particulates and pollutants, installation of fire dampers and flame arresters, and compliance with explosion-proof electrical standards like GB 50058 and GB 3836.15. Equipment must feature anti-static grounding, lightning protection, and emergency discharge systems that activate upon power failure. For Adsorption Equipment (including activated carbon and zeolite), the standard requires temperature sensors within adsorption tanks, automatic cooling devices triggering at specific temperature thresholds, and fire extinguishing systems. For desorption processes, it specifies safety measures for steam, nitrogen, and hot air regeneration, including oxygen content monitoring and concentration limits to prevent explosions. Combustion Equipment (TO, CO, RTO, RCO) must include safety devices such as emergency fuel shut-off valves, over-temperature protectors, and combustion monitoring systems. Combustion chambers require explosion relief devices with specific area and pressure parameters. The standard also restricts the use of certain combustion methods for waste gas containing halogens or heavy metals to prevent catalyst poisoning and secondary pollution. Liquid Absorption Equipment must use non-toxic, chemically stable absorbents and include cooling, regeneration, and waste liquid treatment systems. Explosion-proof transfer pumps are required, and they must be interlocked with the ventilation fans.

Métodos de ensaio

Verification of compliance is achieved through a combination of methods. Visual inspection is used to confirm the presence and basic functionality of safety devices like fire dampers, flame arresters, combustible gas alarms, and emergency discharge systems. Testing and documentation review verify that temperature, pressure, gas concentration, and air leakage rates meet the specified limits. This includes checking explosion-proof certifications, material certificates, and control interlock records. Finally, design verification involves reviewing equipment drawings, calculation books, and manuals to ensure structural and safety integrity, such as confirming flame arresters meet GB 5908 requirements.

Perguntas frequentes

What products are regulated under GB 20101-2025?

GB 20101-2025 regulates safety technical requirements for purification equipment of coating organic waste gas. This includes devices based on adsorption (activated carbon, zeolite), combustion (TO, CO, RTO, RCO), and liquid absorption technologies.

Are there any updates from the previous version of GB 20101-2025?

Yes, GB 20101-2025 replaces GB 20101-2006. Key updates include an expanded scope, new definitions for technologies like zeolite rotors and RCO/RTO, added requirements for control systems and combustible gas alarm placement, and the deletion of certain provisions regarding facility siting and manufacturer qualifications.

What are the key safety features required for combustion-type purification devices?

Combustion devices must be equipped with safety devices including emergency fuel shut-off valves, over-temperature protectors, fuel pressure monitoring, and explosion relief devices. They also require combustible gas alarms at the inlet that trigger safety interlocks when gas concentrations exceed 10% of the lower explosive limit (LEL).
