Sulfur solid-liquid separation device and use method thereof

Abstract

The invention relates to the field of mechanical equipment manufacturing, in particular to a sulfur solid-liquid separation device and a using method thereof.The sulfur solid-liquid separation device comprises a material containing pool for containing a mixture, a driving assembly and a filter plate are arranged on the material containing pool, and the driving assembly drives the filter plate to enter and exit from the mixture; the filter plate is provided with a concave cavity, an opening of the concave cavity is covered with filter cloth, the concave cavity is communicated with a suction assembly used for changing the pressure state in the concave cavity, the concave cavity is in a negative pressure state when the filter plate is located in the mixture, and the concave cavity is in a positive pressure state when the filter plate is located outside the mixture; a scraper for scraping substances on the surface of the filter cloth is arranged on a moving path of the filter plate; according to the invention, the vacuum degree generated by adsorption can be increased, the solid-liquid separation degree of sulfur is improved, and the energy consumption is reduced, so that the reutilization of resources is improved.

Description

technical field [0001] The invention relates to the field of mechanical equipment manufacturing, in particular to a sulfur solid-liquid separation device and a use method thereof. Background technique [0002] Coal contains sulfur, and the sulfur content varies depending on the source and type of coal. During coal gasification or combustion, sulfur in coal is transformed and enriched at high temperature. In coal conversion technology, coal gasification is an important way to clean coal conversion. my country's coal gasification is large in scale and develops rapidly, and a large amount of hydrogen sulfide will be generated during the coal gasification process. [0003] On the one hand, hydrogen sulfide needs to be treated and eliminated as a pollutant. On the other hand, hydrogen sulfide can also be processed and converted as a resource. Therefore, the catalytic conversion of hydrogen sulfide to obtain sulfur has good environmental and economic benefits. In order to obtain...

Problems solved by technology

In order to obtain sulfur products and filtrate, it is necessary to carry out solid-liquid separation treatment on the slurry generated in the above process. At present, a horizontal belt vacuum filter is often used to achieve solid-liquid separation, but the vacuum degree of this type of device is low, resulting in relatively strong adsorption. Small, the amount that can be separated each time is small; the residue on the adsorption surface is not cleaned cleanly, which leads to the blockage of some filter holes and reduces the next adsorption efficiency, so it needs to be solved urgently
