Supercritical carbon dioxide fluid flash explosion machine

Abstract

The invention discloses a supercritical carbon dioxide fluid flash explosion machine. The supercritical carbon dioxide fluid flash explosion machine comprises a high-temperature and high-pressure fluid flash explosion system, a carbon dioxide medium pressurization system, a circulation treatment system and a carbon dioxide separation and recovery system. A high-temperature and high-pressure fluidtreatment area and a fluid flash explosion area are arranged in the high-temperature and high-pressure fluid flash explosion system and communicate through a quick-opening valve, the quick-opening valve can conveniently and rapidly achieve adjustment of different opening degrees and opening rates according to requirements, the requirements for different temperatures and pressures in the final treatment state can be effectively met, and flash explosion machining of materials under different working conditions is achieved. A magnetic stirring system and an external fluid circulation system are arranged in the high-temperature and high-pressure fluid treatment area, and the treatment uniformity of the treated materials is greatly improved. The fluid flash explosion area can achieve anhydrousdry-state machining of the materials, the technological process is shortened, the obvious ecological and environment-friendly characteristics are achieved, and efficient flash explosion treatment of compact type materials difficult to permeate is achieved and improved.

Description

technical field [0001] The invention relates to a supercritical carbon dioxide fluid flash explosion machine, which belongs to the technical field of manufacturing pressure vessels and textile dyeing and finishing processing equipment. Background technique [0002] In recent years, the survival and development of the traditional textile printing and dyeing industry has encountered unprecedented challenges due to high water consumption and prominent ecological and environmental protection issues.
