Industrial sulfuric acid solid-liquid separation system

Abstract

The invention relates to the technical field of sulfuric acid production, in particular to an industrial sulfuric acid solid-liquid separation system which comprises a workbench, an air drying box, a filter box and a transfer box are sequentially and fixedly mounted on the top wall of the workbench from left to right, a guide pipe extending into the filter box is fixedly mounted on the side wall of the transfer box, and a valve is mounted on the guide pipe. Under the action of gravity, liquid flowing out of the guide pipe falls onto the first filter plate, at the moment, the liquid penetrates through the first filter plate and enters the liquid accumulation box, filter residues remain on the surface of the first filter plate, and due to the fact that the first filter plate is obliquely installed, the filter residues are not prone to falling off. Therefore, the filter residues gradually slide into the flow guide pipe along the surface of the first filter plate and move to the surface of the filter screen along the flow guide pipe, after the filter residues are air-dried on the surface of the filter screen, the filter residues enter the filter residue box under the action of the feeding mechanism, and solid-liquid separation is carried out on liquid in the whole process.

Description

technical field [0001] The invention relates to the technical field of sulfuric acid production, in particular to an industrial sulfuric acid solid-liquid separation system. Background technique [0002] In the process of making acid from pyrite, due to the large amount of waste residue produced by roasters and waste heat boilers, the solid waste produced by pyrite acid production, namely high-temperature roasting slag, has always been a problem that plagues production management, site management and comprehensive management of environmental protection. The main reason is that the roasting slag produced by the roaster and the waste heat boiler has a high temperature (850℃-1100℃) and a fine particle size (200mesh-500mesh). The original treatment methods are mostly hydraulic slag flushing or direct slag treatment Water drenching and humidification will cause multiple pollution of dust and water, steam and dust on the production site. Due to the large amount of acidic substance...

Problems solved by technology

[0006] The object of the present invention is to provide a kind of industrial sulfuric acid solid-liquid separation system, to solve the problem that the residual sulfuric acid on the sponge proposed in the above-mentioned background technology will be mixed in the filter residue when the filter residue is extracted by the suction pump, so that the recovered filter residue needs to be used A large amount of clean water is used for cleaning, resulting in the waste of water resources
