One year after the use of biogas digesters, due to the lack of farmer management, there will be excessive debris, sedimentation and other impurities in the pool water, which will lead to a significant drop in gas production, which will seriously affect the normal use of farm households. In order to solve the above problem, it is necessary to refuel the digester. When reloading, pay attention to the following matters: 1.Technical Regulations: Stop feeds 20 days before the big refueling, and prepare enough new raw materials for stacking. When the liquids reach 70%-80% of the total amount (20%-30% of the total content in the digesters should be retained) The active material liquid of methane bacteria is used as an inoculum), and the newly-packed good materials are put into it. The refueling time of biogas digesters should be the most suitable in September. The fermentation speed during this period is fast, which can guarantee the normal use of biogas after the spring, if the refueling time is after the winter in October (the pool temperature is lower than 15), bacterial activity is slow during this period, fermentation Basically stopped, it is difficult to start the digester after the spring, affecting normal use. 2. Accurate operation: When discharging a large quantity, it is necessary to turn off the regulating switch on the purifier (to prevent the desulfurizer from regenerating in the purifier after entering the air and burning the equipment), and to replace and regenerate the desulfurizer at this time. Unplug the air pipe from the air pipe or water bottle and let the air enter the biogas tank to prevent vacuum in the tank. Once a vacuum occurs, the water column in the pressure gauge will fall back into the gas pipeline; it will also cause the paint layer in the pool to fall off, and the sealing performance will deteriorate, and even lead to biogas leakage, resulting in difficult to recover losses. 3. Timing feeding: After large discharge, the water storage ring and the inlet and outlet should be covered to prevent the air from flowing in the tank and dehydrating the air chamber, resulting in crack leakage. 1-2 days should be quickly overhauled biogas digesters, biogas tanks in a timely manner to seal the conservation, in order to improve the closed performance of the biogas digester, continue to use new materials. , 4. Winter insulation: When the temperature drops below 10, the biogas tank should be insulated. The biogas tank can be covered with plastic film, or firewood can be stacked on the biogas tank to ensure the normal fermentation temperature of the biogas digester. Observe that the biogas digester does not produce in the winter. Gas is prone to acidification, and it is not easy to start fermentation in the spring. 5. Safe operation: Do not ignite and smoke within 10 meters of the digester when discharging. Do not use open flame. If you need to clear the bottom of the pool or maintenance must be done to ensure safety measures. The first is that professional security administrators are not present and are not operational. The second is to open the movable cover so that the feed inlet, discharge outlet, and active cover outlet can be ventilated for 2-3 days. The air in the reservoir can be renewed, or a blower with 150 watts can be used to ventilate the air from the outlet to the reservoir for more than 6 hours. The third is to put small animals (chicken, rabbit) into the pool and observe for 15-30 minutes. If the animal activity is normal, you can go to the pool. Fourth, the lower pool personnel need to tie down the rope, the other end of the rope is controlled by others. The staff in the lower pool feels uncomfortable. The nursing staff should immediately pull it out of the pool and take it to the shade of the ventilation.
