多晶硅投产前清洗概况General cleaning of polysilicon before putting into production
多晶硅装置生产中对设备洁净度极高,因此需要投产前对所有管道,精馏塔,过滤器,换热器,各类槽罐,机泵阀门等进行化学除锈,脱脂,钝化,漂洗,高纯水冲洗,氮气干燥等工艺。以保障投产后产品合格率和设备的安全运行。In the production of polysilicon device, the equipment is very clean. Therefore, before the operation, chemical rust removal, degreasing, passivation, rinsing, high purity water washing, nitrogen drying and other technologies are necessary for all pipelines, rectifying towers, filters, heat exchangers, tanks and pump valves. In order to guarantee the product qualification rate and the safe operation of the equipment after production.
