In response to the inherent defects of the traditional sulphuric acid drying and absorption process pump tank negative pressure control device,a new pump tank negative pressure control device renovation plan is proposed and implemented.After the renovation,a balanced and stable micro negative pressure control was achieved for each pump slot in the dry suction process,while solving other problems caused by traditional negative pressure control devices.Through the transformation and application practice of the negative pressure control device for the drying and absorption pump slot,a corresponding optimization scheme for the structure of the dry and absorption pump slot has been further proposed,providing a more reasonable solution for the promotion and application of new pump slot negative pressure pumping devices.
