What are the precautions when dry anaerobic normal operation?

1. When the dry anaerobic reactor is exhausted, the reactor should be connected with the gas storage tank to avoid the formation of negative pressure.

2. The anaerobic reactor overflow pipe needs to maintain a smooth and water-sealed height.

3. To make full use of biogas, the biogas that needs to be discharged needs to be standardized.

4. The water seal of the gas storage cabinet should maintain the height of the water seal. The summer should be supplemented in time. When the temperature is below zero in winter, anti-freezing measures should be taken.

5. The pH value of the water in the water seal of the gas storage tank should be measured regularly. When the pH is less than 6, the water should be replaced.

6. The condensed water in the gas pipeline should be discharged regularly, and the leakage of biogas should be prevented when draining.

The desulfurizer in the desulfurization unit should be regenerated or replaced regularly. Winter temperatures below 0 degrees Celsius, anti-freezing measures should be taken.

8. Dry sulfur rate should be greater than 90%; wet desulfurization,

What is the maintenance and maintenance of dry anaerobic?

1. The instrument should be installed in a place where the air is relatively clean and the temperature change is relatively small.

2. Before starting the machine, you should be fully familiar with and understand the instructions for using instruments and meters, and master the correct method of use.

3. The culture needs to be placed in an oxygen-free environment in the training room.

4. If the cause of failure (the cause of gas stop, etc.) It can be maintained in the operating room, and it can still remain oxygen-free for 12 hours. (More than 12 small, need to take out culture, separate treatment).

5. Pay attention to air leakage.

6. When the gas cylinder is exhausted and the total output pressure is less than 0.1MPa, the gas cylinder should be replaced as soon as possible. When replacing the gas cylinder, pay attention to tighten the gas pipe to prevent oxygen-containing gas from flowing into the pipe.

7. When germicidal lamps are needed, can germicidal lamps radiate strong short-wave ultraviolet rays, which have a strong effect on nucleic acid proteins. It can kill bacterial mutations. At the same time, ultraviolet light is deadly to organic cells. People's eyes and skin are exposed to ultraviolet rays for a long time, so be sure to take out the training room or training room when opening it. After starting up, you should leave the ultraviolet radiation in time to avoid causing human discomfort, such as headache, chest tightness, dizziness and other phenomena.

8. Dry anaerobic machine without electricity. Can check whether the power plug-in terminal is 220V power plug-in. If there is a power supply, you can unplug it. Check whether the fuse on the control panel is blown. If personnel or electrical knowledge is required to replace or maintain the melter, you can also ask the manufacturer. Don't change yourself to avoid accidents and unnecessary losses.

9. When the initial gas replacement or the release of mixed gas at the end of the culture, the doors and windows of the laboratory should be opened or the air outlet should be opened to accelerate the gas circulation. To reduce the release of excess gas and the inhalation of the human body, the anaerobic training box is a special equipment for bacterial culture and operation in an anaerobic environment. The oxygen training box adopts scientific and advanced methods to achieve high precision in anaerobic environment, which is convenient for operators to operate in anaerobic environment and cultivate anaerobic bacteria. It can provide rigorous anaerobic temperature training conditions and system scientific working area. Can be cultured in very difficult to grow anaerobic organisms.

10. Dry anaerobic operation in the atmosphere can avoid the risk of death from oxygen in the atmosphere. Operating room environment coverage: place necessary accessories and appliances as required, and place two non-toxic plastic bags in the operating room. Turn on the power light, turn on the temperature and temperature, adjust the required temperature and safe temperature. Put 1000 grams of melted granules (closed) and 500 grams of desiccant into the operating room, and put into the Mei Lan indicator (closed). Close the door inside and outside the sample chamber and vacuum for verification. Operating room * secondary replacement (nitrogen replacement): first insert a rubber tube into an indoor air inlet, and insert a plastic bag at the other end. Put nitrogen into the gas circuit, open the nitrogen control valve, make two plastic bags enough, and then tie the bags tightly.

11. Place the latex glove on the observation board and tighten. The nitrogen in the plastic bag is gradually put into the internal operating room until it is released. The secondary replacement operating room (nitrogen replacement) repeats the nitrogen filling process. Note that the exhaust is turned on and off at any time using the foot switch. Third replacement of operating room (mixed gas replacement):(mixed gas ratio: n2 85% H2 10% CO2 5%) The mixing tube opens the mixing tube through the air inlet, and the foot should open and close the switch at any time during inflation. When the mixed gas is filled with plastic bags, the mixed gas is closed through the valve (three-way valve) so that the mixed gas can be input and operated, and the flowmeter is adjusted to about 10 ml per minute.

12. The mixed gas in the plastic bag is gradually discharged out of the room. After three times of ventilation, the oxygen content in the indoor gas is in a small amount of micro-expansion. Turn on the granular oxygen, turn on the power supply of the oxygen dehydration catalyst for catalytic removal, and turn on the Meilan indicator (Meilan bottle) to observe the change after one hour. Turn on the ultraviolet germicidal lamp for indoor disinfection. disinfection time. Anaerobic training box note: the installation as quiet as possible, less temperature change. Before starting, you need to be fully familiar with and understand the composition of the supporting instruments and meters, and master the correct use method. Cultures need to be placed in an anaerobic environment in the operating room.

13. If there is a malfunction (gas stop, etc.), the operating room can still maintain an anaerobic state for 12 hours. (For more than 12 hours, remove media as needed). Pay attention to air phenomena. When replacing the gas cylinder, pay attention to tighten the gas pipe to avoid the inflow of oxygen-containing gas. The vacuum pump is used as required to refuel for regular inspections. Stop using it and turn off the main power button and power switch on the back of the device.

Dry anaerobic YQX-II anaerobic training box is a special equipment for bacterial culture and operation in anaerobic environment. It can provide rigorous anaerobic temperature training conditions and system scientific working area. Operated and trained in this device, it is possible to cultivate anaerobic organisms that are difficult to grow. When operating in the atmosphere, the risk of death in the atmosphere can be avoided. Therefore, the device is an ideal tool for anaerobic biological testing and research. This device is also a good instrument. Used in one thing, such as changing the mode of operation to provide good growth conditions for the growth and reproduction of micro-tension.
