Description
技术领域
本发明涉及硫酸生产领域，尤其涉及一种溶硫过滤机卸压装置。
背景技术
硫磺制硫酸用到固体原料硫磺，必须去除工业硫磺中的杂质才能供制硫酸使用，该过程是固体硫磺先熔融成液体硫磺，再经过滤、沉降精制后才能合格供焚转使用。
液体硫磺的过滤是硫磺精制最重要的部分，首先用硅藻土将叶片过滤机进行预涂，合格后再保持一定的流量和压力进行过滤，过滤机截留的滤渣满后要进行清理除渣。除渣前，必须对过滤机进行卸压操作，前期卸压时，常保持过滤机进口、回流阀门打开卸压，但弊端是从过滤机进口卸压时，过滤机内的渣和液磺同时通过泵出口回流至粗硫槽内，常导致泵出口堵塞；以这种自然卸压的方式，最终硫磺渣中的液硫占比还是比较高，每年损失硫磺近200吨。
发明内容
本发明的目的是提出一种溶硫过滤机卸压装置，有助于粗硫泵的长期运行，有助于液磺和渣的分离，减少硫磺损失，有助于过滤机清理。
本发明是通过以下技术方案实现：
一种溶硫过滤机卸压装置，包括粗硫槽和过滤机，过滤机具有进口和出口，所述过滤机进口通过进硫通道与粗硫槽连接，进硫通道上设置有粗硫泵用以提供硫磺进入过滤机的动力，所述过滤机出口通过出硫管道与沉降槽连接，还设置有空气管路，所述空气管路一端与空压机连接，另一端与过滤机连接，与过滤机连接处设置有溢流分路，溢流分路上设置溢流阀；空气管路上从空压机到溢流分路依次设置有压缩空气总阀、压缩空气放空阀和压缩空气阀，所述过滤机出口处还连接设置有回流管道，回流管道另一端与粗硫槽上设置的的回流口连通。
作为优选，所述进硫通道从粗硫槽向过滤机方向依次设置有粗硫阀和止回阀。
作为优选，所述出硫管道上设置有出硫阀。
作为优选，所述回流管道上设置有回流阀。
作为优选，所述溢流阀开启气压为0.2MPa。
作为优选，所述过滤机上设置有压力表。
作为优选，所述回流管道的出口接在粗硫槽上表面，进硫通道伸入到沉降槽底部。
本发明在使用时，通过将压缩空气接至过滤机，卸压时，关过滤机进口阀门，仅开回流阀，利用溢流阀控制过滤机内压力在0.2MPa内，用压缩空气吹尽过滤机内液磺。该方法有助于粗硫泵的长期运行，有助于液磺和渣的分离，减少硫磺损失，有助于过滤机清理。
