摘　　要： 介绍了一种利用回收高压天然气调压过程的压力能为废旧橡胶低温粉碎提供冷源的制冷装置。在此制冷装置中,高压天然气被分成2股,其中一股通过气波制冷机降压产生低温,用于另一股高压天然气的预冷;预冷的高压天然气依次通过气波制冷机和透平膨胀机降压,能够产生-100℃以下的低温,再利用循环氮气作为冷媒为废旧橡胶粉碎提供冷源。此方法不仅能够使高压天然气的压力能得到有效的回收利用,而且能够降低废旧橡胶低温粉碎的成本。 A refrigeration process for tire rubber cryogenic comminution with the pressure energy recovered from natural gas pipelines with high pressure as power is introduced.ln the process,high-pressure natural gas was split into two portions,and one portion of high-pressure gas was expanded to lower pressure in a gas wave refrigerator to produce cryogenic energy used to cool the other portion of high-pressure gas. The cold portion of high-pressure gas was expanded to low pressure in a gas wave refrigerator and an expander orderly,and it could produce a chilling condition lower than - 100% Milch was used to fire rubber comminution. It could not only recover the pressure energy of high-pressure gas, but also reduce the cooling cost for tire cryogenic comminution.
