行业简介 Industry profile

       涂料是涂覆在被保护或被装饰的物体表面,并能与被涂物形成牢固附着的连续薄膜,通常是以树脂、或油、或乳液为主,添加或不添加颜料、填料,添加相应助剂,用有机溶剂或水配制而成的粘稠液体。全球涂料行业的发展趋势是向着减少挥发性有机化合物等方面发展。

       Coating is coated in the protection or decoration of the object surface and can be firmly attached to the coating, usually based on resin, or oil, or emulsion, adding or not adding pigments, fillers, and corresponding additives. A viscous liquid formulated with organic solvents or water. The development trend of the global coating industry is to reduce volatile organic compounds and other aspects of development.

行业特点 Industry characteristics

       调漆房用于油漆的调配,大多靠自然通风,存在VOCs无组织排放。涂料干燥大部分都采用自然风干,有与喷涂车间相连,同在一个密封空间内,也有独立敞开的车间。若是独立敞开车间,涂料干燥过程中产生的VOCs将以无组织形式排放。故涂料行业首先需要做到密封,降低排风量。

       Most of the paint mixing rooms adopts natural air drying, and VOCs are emitted without organization. Coatings are mostly dried by natural air, which is connected with spraying workshop, in a sealed space, and also has an independent open workshop. If the workshop is independent and open, the VOCs produced in the drying process of the coating will be discharged in an unorganized form. Therefore, coating industry needs to seal first, reduce exhaust air volume.

工艺选择 Process selection

        如涂料生产车间具有良好的密封性,则涂料生产废气属于风量小、浓度高、常温,优先选用蓄热式焚烧炉(RTO)处理,该法通过天然气助燃,将有机物加热到分解温度,高温氧化裂解成无害的CO2和H2O,由于涂料行业有机废气浓度较高,正常运行时,设备本身不消耗燃料。

       If the coating workshop has good sealing property, the waste gas of coating production belongs to small air volume, high concentration and normal temperature. The (RTO) treatment of regenerative incinerator is preferred. The organic matter is heated to the decomposition temperature by natural gas combustion aid, and the organic matter is heated to the decomposition temperature by the method of natural gas combustion. High temperature oxidation cracking to harmless CO2 and H2O, due to the high concentration of organic waste gas in the coating industry, the equipment itself does not consume fuel under normal operation.
