Description

一种用于喷涂的环保装置 技术领域
本实用新型涉及喷涂技术领域，尤其涉及一种用于喷涂的环保装置。
背景技术
油漆喷涂是工件表面涂装过程中应用最普遍的技术。油漆喷涂过程中会产生大量含油漆雾、粉尘和挥发性有机物等物质的废气，喷漆废气中的VOCs是导致“光化学烟雾”、雾霾等恶劣天气的诱因之一，国家一直很重视对该类废气的收集治理，出台了一系列的整治文件。在该类废气治理过程中，由于废气中油漆雾的高粘性、细颗粒的特点，导致后续的VOCs废气治理技术运行极不稳定，对油漆雾的去除是油漆喷涂废气治理设施的预处理系统，也是保证系统持续稳定运行的关键技术。
现有技术中，常见的用于喷涂的装置只是进行简单的一次过滤，去除粉尘和喷涂后的油漆并不彻底；大多数有毒有害的气体和颗粒会残留到空气中。因此在喷涂过程中会产生严重的环境污染，也会影响到工人的身体健康。
