化工生产过程中的反应生成气,一般都用冷冻机来进行冷凝分离,而日本三菱重工业公司引进法国 NAT 公司的技术,开发了旋转喷咀式膨胀机,利用反应生成气本身的压力,不要外来能量,在接近等熵的条件下绝热膨胀进行制冷,来冷凝分离生成气的成分,该膨胀机结构简单,适应节能的要求。 Chemical reaction process gas production, the general use of freezers for condensation separation, and Japan’s Mitsubishi Heavy Industries introduced the French NAT company’s technology, the development of rotary nozzle expander, the pressure of the reaction to generate gas itself, do not outside Energy, adiabatic expansion near the isentropic conditions for refrigeration, to condense and separate the components of the generated gas, the expander structure is simple, to meet the energy-saving requirements.
