Bottom discharge hydraulic diseased methane tank maintenance method

The “four-in-one” rural energy and ecological model, biogas digester is the core part of the whole model. Whether it can operate normally will directly affect the overall benefit of the “model”. The diseased pool is caused by impeded fermentation or design, building materials, construction and management, resulting in leaks and leaks in the pool and failure in normal operation. 1. The inside of the pool is covered with shells, cracks, and shedding. Maintenance method: Brush the inner wall of the pool and dry it. Brush it with cement slurry, then wipe it again with 115 cement mortar. The thickness is about 3 mm. Thin, uniform, full, compacted, polished, no trachoma. After drying, brushing 24 times with plain grout, you can also use water glass and grout to alternately brush 2 times. You can also use neoprene latex asphalt (0.25 kg per square meter), wipe it evenly with a brush 3 times. Every time the brushing direction is vertical, each time must wait for the previous coating to dry before brushing (usually 244 hours interval), after brushing in the air to protect the water for 7 days, you can feed. Second, the cracks in the pool maintenance methods: first deepen the gap into a deep V-type, the surrounding surface of the hair, the loose concrete blocks and dust clean, brush the paste again in the V-shaped groove and pull the hair, and then use 1 : 2 cement mortar in the joints, compaction wipe, and finally brush the slurry twice. Third, the bottom of the pool along the collapse of maintenance methods: the use of large hammers together with the concrete bottom of the pool, until no longer hammer marks. Fill it with gravel, then pour 5cm thick with 200# soil, then use 10mm diameter steel reinforcement and upper corner of the pool bottom, and then use a 200# concrete to build 5cm thick to make it an organic whole. Concave light, no trachoma appears. Fourth, the pool wall and the bottom of the pool at the crack repair method: first crack open a 3 cm wide, deep 3 to 5 cm groove, clean and loose concrete and dust, brush again the cement slurry. Then use 200# fine stone concrete to fill and flatten the groove, then use the concrete to pour the pool wall and the bottom of the pool into a fillet, flatten and polish. Fifth, cover the activities cover specific practices: First clean the pool mouth and the movable cover, sealed with a sticky mud pool, the top of the activity cover and pool mouth to leave a 10 to 15 cm deep mouth, and then 1:2 cement mortar Yan After the cement is slightly condensed, brush the slurry 14 times. Sixth, the active cover seal leakage maintenance methods: the biogas run out or let go, so that the pressure is reduced. Then clean the surrounding area of ​​the movable cover, remove the air leakage part with a weapon such as iron nails (appropriately expand some), and then rinse with water, and then squeeze the dry cement into the leak part, and the moisture content of the leak part. It can make the cement reach the tidal temperature. After 24 hours, add water to cure. If the seal is seriously damaged, 12 cement mortar can be used for repair. Seventh, the air pipe breaks the repair method: Uses the steel solder to cut a small pit of 10 to 15 centimeters deep in the airway tube lightly, causes the air tube to expose, cleans with the clean water, brushes a layer of cement paste. Connect the gas pipe, close it with mortar, and use a pipe with an inner diameter of 44 cm to protect the gas pipe. Eight, switch leakage repair methods: whether metal or plastic switch, the switch torsion, twist the rotating shaft, the mechanical butter smear on the shaft, re-assemble it. Mechanical butter is both leak-proof and lubricated. Remember that butter does not block the vents.
