Comparison of Four Gasification Coarse Slag Drainage Technologies
In order to select the most suitable drainage method for gasification furnace slag,combined with the actual operation of four slag extractors in a certain device for subsequent drainage,a water box was set up at the bottom of the slag truck,and the carriage was sealed.At the same time,a drainage filter plate and a water guide hose were set up at the bottom of the carriage,a drainage filter plate and a drainage system were set up at the side cone of the slag hopper of the slag scraper,and a two-stage large angle slag scraper was set up with a drainage filter plate and a drainage system.The water content,environmental pollution,investment and operation cost,and stable operation cycle of the four slag drainage technologies were compared.The vacuum drain type has the lowest moisture content,is easy to operate and maintain,runs stably,and has a longer cycle.
