Problems solved by technology
However, the disadvantage of using this method to recycle flash steam is that since the process of heating hot water through the heat exchanger is a dynamic process (cold water enters from one end of the heat exchanger, hot water exits from the other end of the pipe, water It flows in the heat exchanger and is continuously heated), which requires that the heated medium is also continuous and uninterrupted, and the flow rate meets a fixed demand (such as industrial steam prepared by a boiler), but the characteristics of flash steam are intermittent, not It is generated regularly, and the amount generated at the same time is not fixed, sometimes large and sometimes small, so this method must be equipped with steam as a heating auxiliary medium, and the heating requirements of hot water are met through self-control technology, which not only increases the recovery cost, but also controls The system is relatively complex, with poor stability and reliability, and it is extremely difficult for continuous heating conditions

The invention relates to a waste liquor inactivating device utilizing flash steam. The waste liquor inactivating device utilizing the flash steam comprises two independent waste liquor inactivating tanks, wherein a liquor inlet connector, a flash steam inlet connector, a water inlet connector, an industrial steam inlet connector, an air exhaust connector and a safety valve are arranged at the top of each waste liquor inactivating tank, a control valve is arranged on each of the liquor inlet connectors, the flash steam inlet connectors, the water inlet connectors, the industrial steam inlet connectors and the air exhaust connectors, a liquor discharging connector is arranged at the bottom of each waste liquor inactivating tank, and a control valve is arranged on each liquor discharging connector. The waste liquor inactivating device utilizing the flash steam has the advantages that waste liquor is inactivated by introducing the flash steam into the waste liquor inactivating tanks, so that quantity of industrial steam in the waste liquor inactivating tanks is greatly reduced, and recycling of heat energy is effectively realized; and the two waste liquor inactivating tanks are arranged, so that the two waste liquor inactivating tanks can alternately inactivate the waste liquor, produced waste liquor can be continuously inactivated, recycling of the heat energy is guaranteed, and production cost is reduced.
Description
technical field [0001] The invention relates to a flash steam recycling device, in particular to a waste liquid deactivation device utilizing flash steam. Background technique [0002] At present, in biopharmaceutical projects, because microorganisms are the most important products in process production, such as bacteria, fungi, viruses, etc., there are often a large number of active microorganisms in the production waste liquid, and we must conduct a unified waste collection for waste liquid collection. After liquid inactivation treatment, it can be discharged to the outdoor wastewater pipe network to the sewage treatment station for subsequent treatment. In the current biological waste liquid inactivation treatment method, high-temperature sterilization is one of the most important methods, such as sterilization at 121°C for 15 minutes, and the heat source for sterilization mainly comes from industrial steam. Convenience, reliability, high efficiency and low cost. In the...
