Sterile air preparation system and method for preparing acrylamide by biological method

Abstract

The invention relates to a sterile air preparation system and method for preparing acrylamide through a biological method, and relates to the technical field of chemical production, the sterile air preparation system comprises a rough filtration compression thermal sterilization gas production unit, a double-cooling separation heating unit and a secondary filtration gas supply unit, the rough filtration compression thermal sterilization gas production unit is connected with the double-cooling separation heating unit through a compressed air pipeline, and the double-cooling separation heating unit is connected with the secondary filtration gas supply unit; high-altitude air collected after filtration and high-temperature sterilization is introduced into the double-cooling separation heating unit; the double-cooling separation heating unit is connected with the secondary filtering air supply unit through a compressed air pipeline, so that the air subjected to two-time separation is cooled to 30-35 DEG C and enters the secondary filtering air supply unit; and the secondary filtering air supply unit is used for introducing filtered sterile air into the strain chamber through two groups of sterile air delivery pipes. The device has the advantages that the sterile standard and the automation degree are high, the preparation process is energy-saving and environment-friendly, and the operation is stable.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a system and method for preparing sterile air for acrylamide by biological method. Background technique [0002] The production process of acrylamide by biological method requires a certain amount of sterile air to be injected in sections after the inoculation of the bacteria, the first fermentation and the second fermentation, and the separation of mycelia into the hydration reactor for hydration reaction. Directly affect the quality of the fermentation of the strain and the subsequent hydration reaction: the quality of sterile air is too high, the effect is good, but the production cost is high and uneconomical. The air quality of simple filtration cannot meet the requirements of the biological acrylamide production process. Suitable aseptic air contains less other microorganisms, and effectively inhibits the rapid reproduction and growth of other microorganisms, p...
