TVA改良法的埋床式管状反应器系一将硫酸与合成氨先行分别分散,再令其反应进入粒化机内的滚动料床内,化学反应完全,化学反应热利用率高。从使用埋床式管状反应器的台湾厂与大陆使用悬空式管状反应器的类似工厂的比较,大陆类似工厂若改用埋床式管状反应器,年产量10万t的粒状复合肥厂,每年可因使用低价原料,减少动力、燃料、蒸汽消耗而减少支出2100多万元,并可提高产量72%。由于TVA改良法的化学造粒,成品颗粒坚硬耐水,肥素缓释,并可减少对河川的污染。
TVA modified method of buried tubular reactor is a first line of sulfuric acid and ammonia were dispersed, and then make it into the granulator within the rolling material bed, the chemical reaction is complete, high chemical reaction heat utilization. From the use of buried tubular reactor plant in Taiwan and the mainland use of suspended tubular reactor similar to the factory, the mainland if the switch to a similar plant buried tubular reactor, annual output of 100,000 tons of granular compound fertilizer plant, annual Due to the use of low-cost raw materials, reduce power, fuel, steam consumption and reduce spending more than 21 million yuan, and can increase production 72%. Due to the chemical granulation of the TVA Modified Method, the finished granules are hard and water-resistant, with slow release of the emollients and reduce the pollution of the river.
