The utility model relates to a safety explosion-proof type sodium hydride adding device, which is a whole structure. The feeding tank is a cylindrical tank with a conical bottom, and the side is provided with a nitrogen air pipe, and the upper cover is provided with a closed cover. A measuring tank with an upper mirror and a lower gate valve is communicated with the bottom of the charging tank under the conical bottom. The lower end of the measuring tank is a nozzle connecting pipe. Both the upper and lower gate valves of the measuring tank are provided with closed film. The material of the adding device is plastic, and the sealing film is made of rubber or plastic. The utility model has the advantages that the structure is simple, the safety is explosion-proof, and the production is maintained normally, and the quality and the yield of the product can be improved, and the cost is reduced.
【技术实现步骤摘要】
术领域本技术专门用于生产中需要有氢化钠参加反应的化工产品的生产过程 中,它与反应釜配套使用。
技术介绍
目前各种化工反应釜均无配套的氢化钠添加装置。如在生产中需要添加氢 化钠,通常采用下列办法-由于氢化钠在水中能爆炸,在空气中能自动燃烧,故添加时需特别注意, 需少量多次添加。具体操作方法是,开启反应釜的氢化钠添加管口,向釜中添 加少量氢钠并立即封闭管口,隔一段时间,再开启添加管口,再加少量氢化钠 并立即封闭管口。需多次重复这种操作,直至加完。氢化钠在水里发生爆炸是因为它与水发生化学反应产生氢气NaH+H20 ~~^ NaOH+H2氢气与空气混合达到一定体积比,即行爆炸。氢化钠在空气中自动燃烧,是因为氢化钠迂空气中水气反应生成氢气,氢 气又与空气中的氧气剧烈氧化燃烧-2H2+02 ~"^2H20综合所述,用现有反应釜添加氢化钠的方法,操作特别繁琐,且极具危险性。
