Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1, the novel continuous inactivation system of the present embodiment includes a waste water collection tank 10, a delivery pump 20, a heat recovery unit 30, a steam-water mixed heater 40, a heat preservation unit 50, a CIP cleaning tank 60 and a three-way valve 70, biological waste water is stored in the waste water collection tank 10, a water outlet of the waste water collection tank 10 is sequentially connected with the delivery pump 20 in series through a first pipeline 80, the heat recovery unit 30, the steam-water mixed heater 40 and the heat preservation unit 50, a water outlet of the heat preservation unit 50 is communicated with a return port of the waste water collection tank 10 through a second pipeline 90, the three-way valve 70 is installed on the second pipeline 90, one of liquid outlets of the three-way valve 70 is communicated with the return port of the heat recovery unit 30, a cleaning liquid is stored in the CIP cleaning tank 60, and a pipe section of the first pipeline 80 between the waste water collection tank 10 and the delivery.

During the use, biological waste water carries in proper order through delivery pump 20 and preheats in the heat recovery unit 30, carries and heats to the inactivation temperature in steam-water mixing heater 40, carries and inactivates in the heat preservation unit 50, and after the inactivation finishes, control three-way valve 70 makes biological waste water in the heat preservation unit 50 get into in the heat recovery unit 30, carries out the heat transfer cooling with new batch biological waste water, and the biological waste water of waiting to inactivate cools off to safe discharge temperature back, discharges it. The heat recovery unit 30 can recycle heat in the inactivated biological wastewater, thereby saving cost. Because biological waste water has a large amount of dirt, the dirt stagnation can make the equipment pipeline produce the scale deposit in the equipment, influence equipment use, so after biological waste water deactivation finishes discharging, utilize delivery pump 20 to pump the washing liquid in CIP washs jar 60 into inside the whole system and wash each pipeline, can avoid the impurity in the biological waste water to block up the pipeline, prevent to produce the peculiar smell, the life of each equipment in the extension system, wherein, the washing liquid can be clear water, alkali lye etc..
