Red mud biogas bag use and maintenance methods, red mud biogas bag products, detailed introduction of red mud biogas bag price and installation, biogas bag collapsible biogas bag, biogas process flow chart, rural biogas equipment purchase, red mud biogas bag, please call Manager of Hongjing Environmental Protection Chen understands the introduction of “Red Mud Gas Bag†1.1 Fermentation Inoculum Rural biogas fermentation inoculum Generally, a certain amount of human and animal waste is added by the fermentation broth of the old red mud biogas bag. For example, to prepare 500 kg of fermentation inoculum, generally 200 kg of biogas fermentation broth and 300 kg of human and animal feces are mixed, stacked in a water-tight pit and sealed with a plastic film, and used as an inoculum after one week. If there is no biogas fermentation broth, it can be directly packed with 500kg of human and animal waste, and it can be used as biogas fermentation inoculum after 10 days. 1.2 The red mud biogas bag is filled and the sealing performance of the red mud biogas bag is checked to meet the requirements. There are many kinds of biogas fermentation materials, and various organic substances can be used as biogas fermentation materials. Such as: human and livestock poultry manure, crop straw, agricultural and sideline products waste, domestic sewage. The amount of feed should be 60% to 65% of the volume of the red mud biogas bag. After the feed is completed, the water is added to the pool. The amount of water added is 20 cm higher than that of the dry material. Zuihao is a sewage, manure and biogas slurry with higher temperature. It is forbidden to directly extract cold water from the well to avoid red mud gas bag. It is in a "cold immersion" state and is difficult to start. 1.3 Red Mud Gas Bag Starts The second day after the general red mud biogas bag is put into operation, the rise of the barometer can be observed, indicating that gas has been generated in the red mud gas bag. Initially, the gas produced is released (until the barometer drops to zero). Because the gas produced in the early stage of biogas fermentation is mainly carbon dioxide gas, and there is a large amount of air in the pool. The methane gas content is low and usually cannot be burned. When the barometer rises again, it will ignite on the cooker. If it can ignite, it indicates that the red mud biogas bag has started normally. Otherwise, try again as above. 1.4 Red mud biogas bag discharge After the flammable gas generated by the red mud biogas bag is used, the waste must be taken out, and safety must be taken when discharging. Because the red mud biogas bag is fermented in an anaerobic state for a long time, there is no oxygen in the pool, and people are prone to danger after entering. First, open the lid of the pool and ventilate for a certain period of time. Then, ignite the candle and put the candle into the pool with a rope. The candle can continue to burn and the person can enter. If the candle is extinguished, the person cannot enter. 2. Maintenance and fault handling 2.1 The gas pipeline is often inspected for the gas pipeline. The inspection method is: unplug the gas pipeline from the red mud biogas bag air pipe, connect a switch on the gas pipe, and close the lamp and the switch before the stove. One end of the air pipe connecting switch blows or inflates into the gas pipe. When the pressure on the pressure gauge reaches 30 cm water column height, the switch is turned off and the pressure gauge is observed for 3 minutes. When the pressure gauge drops to indicate air leakage, use the above method to raise the pressure to 30 cm water column height, then apply soapy water to the gas pipeline and switch. The place where the air bubbles are generated is the place where the air leaks, and should be repaired and replaced. 2.2 Leakage and air leakage 2.2.1 Carefully observe whether there are cracks or pores on the inner wall of the red mud biogas bag. If the air pipe is loose, use a finger or a small wooden stick to strike the whole area of ​​the pool. Observe the water wall traces. If there is no obvious water seepage, the surface should be cleaned and evenly spread a layer of dry cement powder. If there is a wet or wet line, it will be a leaking hole or a water leaking seam. 2.2.2 Fill the pool with water. After the pool wall absorbs enough water, mark the water level every other day and night. If the water level does not drop, it indicates that the red mud biogas bag does not leak water. If the water level drops to a certain position, it will not drop, indicating that the water is leaking. Mark the water line, carefully look for cracks or pores above the water line, and then drain and repair. 2.2.3 After checking the water leakage by the above method, seal the sealing cover, connect the tee on the gas transmission pipe, connect the pressure gauge to one end, and pump the air to the other end with qiqiang. When the pressure of the pressure gauge reaches 80cm water column, turn off the air switch. After 24 hours, if the water column of the pressure gauge drops 3 to 4 cm, it indicates air leakage. If the water column drops to a certain position, it will not drop, indicating that the pool has no air leakage. When testing the water test pressure, when the water column on the pressure gauge rises to the design position, the pressure is first fast and then slow down to indicate the water leakage, and the uniform speed drop is the air leakage. It was found that water leakage and air leakage were repaired in time. 2.3 The reason for not producing gas is: there is not enough biogas bacteria; the temperature of the liquid in the tank is low; the concentration of the fermentation liquid is too large. Solution: Add appropriate amount of bacteria to increase the temperature inside the pool. Hongjing Environmental Manager Chen WeChat tongbu QQ http://news.chinawj.com.cn
High Speed Door Motor And Control Box
Our company have German SEW Motor, Japan Mitsubishi Controller. Our own brand Hofic servo motor and controller. Chinese famous brand SEJ motor and Holip controller.
About our German SEW Motor and Japan Mitsubishi Controller: It is easy to find the ideal energy-efficient motor for your application at SEW.
