Stirring device of slurry storage tank

Abstract

The invention relates to a slurry storage tank stirring device which comprises a slurry pump, an external connecting pipe, a slurry spraying main pipe and a slurry spraying disc. The slurry spraying disc is arranged in the slurry storage tank and above the slurry level, a slurry spraying main pipe is arranged above the slurry spraying disc, one end of the slurry spraying main pipe is connected with the slurry spraying disc, the other end of the slurry spraying main pipe is connected with a slurry outlet in the bottom of the slurry storage tank through an external connecting pipe, and a slurry pump is arranged on the external connecting pipe; the guniting disc is composed of a plurality of guniting ring pipes, a plurality of radial communicating pipes and a plurality of nozzles, the multiple guniting ring pipes are coaxially arranged from inside to outside, every two adjacent guniting ring pipes are communicated through the multiple radial communicating pipes, and the multiple nozzles are arranged at the bottom of each guniting ring pipe. Slurry is pumped by the slurry pump, and is uniformly sprayed on the upper part of the sulfur slurry level through the jet nozzle, so that a foam layer at the top of sulfur slurry is eliminated, and the sulfur slurry in the slurry storage tank is uniformly mixed.

Description

technical field [0001] The invention relates to the technical field of desulfurization waste liquid treatment, in particular to a stirring device for a slurry storage tank. Background technique [0002] Using low-quality sulfur and auxiliary salt waste liquid produced by HPF, PDS and other ammonia-based wet oxidation desulfurization processes as raw materials to produce sulfuric acid is a conventional treatment method for desulfurization waste liquid. The pretreatment process of this process is used to complete the sulfuric acid raw material sulfur Preparation and storage of pulp. The specific process is: the sulfur foam liquid sent from the desulfurization unit is centrifugally separated by the centrifuge, and concentrated and dehydrated by the concentration tower to obtain the raw material sulfur slurry for the incineration process, which is sent to the slurry storage tank, and then pumped for incineration in the incineration process. furnace. [0003] Raw sulfur slurry ...

Problems solved by technology

However, with this stirring method, the sulfur foam layer often appears on the top of the sulfur slurry after stirring, which affects the uniformity of the sulfur slurry components.
