Embodiment 1
[0038] Such as figure 1 and figure 2 Shown is a kind of equipment that applies ozone disinfection water to microbial fermentation, the equipment includes a water treatment system and an ozone unit; the water treatment system includes a water storage tank 1, and the bottom of the water storage tank 1 is provided with a The mixing pump 2 is connected and is used to send the water in the water storage tank 1 into the first liquid outlet pipe 1-1 in the gas-liquid mixing pump 2, and the sterile pipeline 1-2 communicating with the fermenter 16; The liquid outlet of the gas-liquid mixing pump 2 is provided with a second liquid outlet pipe 2-1 communicated with the gas-liquid separation tank 3, and the top of the gas-liquid separation tank 3 is provided with an It is used to send the gas separated in the gas-liquid separation tank 3 into the first gas outlet pipe 3-1 in the tail gas processor 4. One side of the gas-liquid separation tank 3 is provided with a water storage tank 1 fo...
Embodiment 2
[0047] Adopt the equipment of embodiment 1 to carry out disinfection and sterilization to microbial fermentation water:
[0048] Step 1. Close the sterile pipeline 1-2 of the water storage tank 1, close the ozone eliminator 5, inject 900L of water into the water storage tank 1, turn on the gas-liquid mixing pump 2, and the water passes through the first liquid outlet pipe 1-1 Flow into the gas-liquid mixing pump 2 from the water storage tank 1, and control the opening degree of the first valve 6 so as to adjust the flow rate of water in the first liquid outlet pipe 1-1 so that the vacuum degree of the vacuum gauge 7 is 0.005MPa, which means The measured volume flow rate of water is 30L / min;
[0049] Step 2: Start the oxygen generator 11 to produce oxygen, adjust the oxygen flow rate, wait for the pressure of the second pressure gauge 14 to reach 0.015MPa, keep it for 3 minutes, start the ozone generator 12 to prepare ozone, and open the stop valve 15 at the same time to make t...
Embodiment 3
[0054] Adopt the equipment of embodiment 1 to carry out disinfection and sterilization to microbial fermentation water:
[0055] Step 1. Close the sterile pipeline 1-2 of the water storage tank 1, close the ozone eliminator 5, inject 1000L of water into the water storage tank 1, turn on the gas-liquid mixing pump 2, and the water passes through the first liquid outlet pipe 1-1 Flow into the gas-liquid mixing pump 2 from the water storage tank 1, and control the opening degree of the first valve 6 so as to adjust the flow rate of water in the first liquid outlet pipe 1-1 so that the vacuum degree of the vacuum gauge 7 is 0.015MPa. The volume flow rate of water measured at the time is 20L / min;
[0056] Step 2: Start the oxygen generator 11 to produce oxygen, adjust the oxygen flow rate, wait for the pressure of the second pressure gauge 14 to reach 0.030MPa, keep it for 5 minutes, start the ozone generator 12 to prepare ozone, and open the stop valve 15 at the same time to make ...
