This invention discloses a Sophora japonica bud threshing device and method. The threshing device includes a drum open at both ends, with a door cover at each opening. The drum wall has sieve holes and a toothed ring. A hopper is located below the drum, a support is provided around the drum, and a scraper is provided on the inner wall of the drum. The threshing method includes the following steps: 1) collecting and high-temperature treating the Sophora japonica buds; 2) threshing the Sophora japonica buds: the high-temperature treated Sophora japonica buds are fed into the threshing device of this invention for rolling threshing. Existing mechanized threshing of Sophora japonica buds is carried out while the buds are fresh, resulting in poor threshing efficiency. This invention adopts a method of high-temperature fumigation treatment of the Sophora japonica buds followed by mechanized threshing, and a threshing device is specifically designed for this purpose. This invention enables complete threshing of Sophora japonica buds. Compared with traditional methods that require manual kneading and beating to achieve complete threshing, the threshing operation of this invention is time-saving and labor-saving, and has good prospects for widespread application.

The utility model discloses a recycle gas compressor energy-saving system of an ethylene oxide device, which belongs to the technical field of ethylene oxide production and comprises an EO absorption tower, a recycle gas compressor, a recycle gas compressor surface cooler, an EO desorption tower, an EO desorption tower reboiler, a secondary cooler, an EO lean and rich absorption liquid plate heat exchanger a, a light component removal tower reboiler and an EO refining tower reboiler. The EO desorption tower kettle pump and the newly added EO lean and rich absorption liquid plate heat exchanger b can be used for reutilizing the circulating water return of the circulating gas compressor surface air cooler, and the shell pass of the EO lean and rich absorption liquid plate heat exchanger b is connected with the EO refining tower reboiler, the EO lean and rich absorption liquid plate heat exchanger a and the EO desorption tower through pipelines. The energy utilization efficiency is improved, the cooling capacity of circulating water is fully utilized, the circulating water quantity of the device is reduced, and the technology is mainly applied to ethylene oxide production.
