For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB 3836.15 Explosive atmospheres - Part 15: Code for design, selection and installation of electrical installations GB/T 4213 Pneumatic control valves GB 5908 Flame arresters GB 12158 General requirements for prevention of static electricity accidents GB/T 14441 Safety terminology for coating operations GB 15930 Fire dampers for building ventilation and smoke exhaust systems GB/T 19839 General technical conditions for industrial fuel/gas burners GB 50057 Code for design of lightning protection of buildings GB 50058 Code for design of electrical installations in explosive hazardous environments GB/T 50087 Code for design of noise control in industrial enterprises TSG 21 Safety technical supervision regulations for stationary pressure vessels 3 Terms and definitions The terms and definitions defined in GB/T 14441 and the following apply to this document. 3.1 organic waste gas; exhaust organic gas gas containing organic compounds generated during coating operations 3.2 purification equipment equipment used to reduce or remove organic substances from organic waste gas Note: It mainly includes purification devices, control systems, auxiliary equipment, filters, flame arresters, detection instruments for temperature, concentration, pressure, alarm, etc., as well as fire extinguishing, explosion-proof and safety interlock control devices. 3.3 activated carbon adsorption purification method that uses activated carbon (such as granular, honeycomb or fibrous activated carbon) as the adsorbent to adsorb and purify organic waste gas 3.4 zeolite adsorption purification method that uses hydrophobic zeolite (molecular sieve) as the adsorbent (such as granular or honeycomb zeolite) to adsorb and purify organic waste gas 3.5 zeolite rotor wheel disc-shaped or cylindrical adsorption, purification, desorption and regeneration device made of zeolite Note: The rotor is divided into three zones: adsorption zone, desorption zone and cooling zone. Driven by a motor to rotate continuously, it cyclically completes the processes of adsorption purification, desorption regeneration and cooling. 3.6 catalytic oxidation; CO purification method where organic gases undergo sufficient oxidation (flameless combustion) through the catalytic action of a catalyst at a temperature of 250°C~350°C 3.7 regenerative catalytic oxidation; RCO catalytic combustion purification method that uses refractory heat storage materials as heat transfer carriers to store the heat generated by catalytic combustion, heat the waste gas to be treated, increase the preheating temperature of organic waste gas, and make full use of waste heat 3.8 thermal oxidation; TO purification method that uses heat generated by fuel combustion to heat organic waste gas to 750°C~850°C for sufficient combustion (oxidation) 3.9 regenerative thermal oxidation; RTO thermal combustion purification method that uses refractory heat storage materials as heat transfer carriers to store the heat generated by thermal combustion, heat the waste gas to be treated, increase the preheating temperature of organic waste gas, and make full use of waste heat 3.10 liquid absorption purification method that uses an appropriate liquid as the absorbent to absorb organic waste gas through physical and chemical reactions during sufficient gas-liquid contact 4 General requirements 4.1 For organic waste gas generated during coating operations, appropriate coating organic waste gas purification equipment (hereinafter referred to as "purification equipment") shall be selected according to the coating process conditions and the nature of the organic waste gas. See Annex A for the characteristics and safety assessment of the purification equipment. 4.2 A pretreatment device shall be installed at the inlet of the purification equipment to remove impurities such as particulate matter, aerosols, oil fumes and liquid droplets, as well as pollutants of other properties such as acids and alkalis in the waste gas. A differential pressure detection device shall be installed for the pretreatment device. 4.3 A fire damper shall be installed between the adsorption-type purification equipment and the organic waste gas source, and the fire damper shall comply with the provisions of GB 15930. A flame arrester shall be installed before the combustion-type purification equipment, and the flame arrester shall comply with the provisions of GB 5908. 4.4 For purification equipment installed in an environment containing explosive gas, its electrical equipment and electrical circuits shall comply with the provisions of GB 50058 and GB 3836.15. 4.5 Both the purification equipment and pipelines shall be provided with antistatic grounding, which shall comply with the provisions of GB 12158. 4.6 The thermal insulation layer of the purification equipment shall be made of non-combustible materials. 4.7 The outer wall temperature of the thermal insulation layer of the purification equipment shall not exceed 60°C.
