Abstract
本发明涉及一种硫化氢泄漏吸消液及用途,主要解决现有技术中清除效率低且易造成二次污的问题。本发明通过采用一种硫化氢泄漏吸消液,由关键氧化剂、辅助氧化剂、吸收剂、吸收强化剂和调节剂以质量比1‑10:0.01‑0.1:1‑5:0.01‑0.1:0.01‑0.5组成,其中辅助氧化剂为H2O2、KClO3、KMnO4、MnO2中的至少一种,吸收剂为二乙醇胺、三乙醇胺、异丙醇胺、甲基二乙醇胺、聚乙二醇二甲醚中的至少一种;吸收强化剂为甘氨酸、环丁砜中的至少一种;调节剂为柠檬酸钠、柠檬酸钾、乳酸、酒石酸、苹果酸中的至少一种的技术方案较好地解决了上述问题,可用于硫化氢气体泄漏应急清除中。
Description
技术领域
本发明涉及一种硫化氢泄漏吸消液及用途。
背景技术
硫化氢主要产生于采矿、含硫石油的开采、橡胶、硫化染料、造纸、菜腌溃、甜菜制糖、动物胶等行业。还存在于沼泽地、沟渠、水井、下水道、涵洞、隧道和垃圾堆、粪便池、污水池等场所。由于硫化氢比空气重,很容易流进或滞留在低洼地、地下室和楼房的底层等处,同时在疏通下水道和清洗污水池时,污水的搅动亦会使溶在水中的硫化氢大量地释放出来,从而增加了这些场所空气中的硫化氢浓度。硫化氢中毒事件具有突发性和群体性,死亡率高,一旦发生,将严重威胁职工和群众的人身安全,并且次生灾害影响大,严重污染大气环境,甚至破坏生态环境。我国对环境大气、车间空气及工业废气中硫化氢浓度已有严格规定:居民区环境大气中硫化氢的最高浓度不得超过0.01mg/m3;车间工作地点空气中硫化氢最高浓度不得超过10mg/m3;城市煤气中硫化氢浓度不得超过20mg/m3;油品炼厂废气中硫化氢浓度要求净化至10-20mg/m3。
而目前针对硫化氢气体泄漏的主要措施大都采用强风吹扫、消防水喷淋等方法,但诸如此类的方法清除硫化氢效率低下,同时还会产生大量含硫化氢废水等。
中国专利CN101648108B《硫化氢气体泄漏清除剂》中公开了一种硫化氢气体泄漏清除剂,由惰性载体、活性净化物质和疏水性物质组成,其中惰性载体为云母粉、氧化镁、活性炭等,活性净化物质为硅酸钠、氢氧化钠和金属锌化合物,但该类清除剂与气体接触不匀,且脱硫效率较低。中国专利CN102423609B《一种硫化氢泄漏捕消剂》公开了一种硫化氢气体泄漏的捕消剂,包括粉体物料,包括镁、锌的氧化物和/或碳化物;水溶性物料,包括强碱和/或强碱盐;液体物料包括硅油和/或水溶性有机溶剂,但该类硫化氢捕消剂需按照上述比例依次加入水中,混合搅拌均匀,反应至糊状后烘干、粉粹成粉末状,制备方法繁琐耗时,脱硫效率不高,且捕消后的固体粉末易造成二次环境污染。
发明内容
本发明所要解决的技术问题之一是现有技术中清除效率低且易造成二次污染的问题,提供一种新的硫化氢泄漏吸消液,具有清除效率高且不易造成二次污的优点。本发明所要解决的技术问题之二是提供一种与解决的技术问题之一相对应的硫化氢泄漏吸消液的用途。
