Research and Application on Hydraulic Model Test of Auxiliary Spray Guns in Hazardous Waste Melting Furnace
A plasma melting furnace of a 10 000 t/a solid waste disposal system in Guangdong province was taken as an example,the auxiliary spray gun hydraulic model test and industrial application of the hazardous waste plasma melting furnace were carried out by setting up a hydraulic model test platform.The results showed that as the spray gun load increased,the penetration depth,splash height,amplitude and material discharge ratio gradually increased.As the height of the spray gun arrangement increased,the penetration depth,splash height,amplitude and material discharge ratio gradually decreased.Compared with the staggered layout schemes,the penetration depth,splash height,amplitude and material discharge ratio of symmetrical layout were smaller.Finally,the auxiliary gun design scheme of the prototype furnace body was determined as the gun layout height was 250 mm and symmetrical layout.According to this plan,the on-site renovation achieved the expected effect,with 28.6%reduction in plasma torch power consumption,13.2%reduction in system power consumption after considering oxygen preparation,and 9.8%reduction in hourly operating costs.
