As a clean energy, biogas is flammable, explosive and toxic. At present, the large-scale use of biogas in rural areas to replace traditional bio-energy such as straw and firewood, the comprehensive benefits are increasingly apparent, but due to non-standard operation and other reasons, there are also some potential safety hazards. Biological desulfurization of biogas reminds you that the safety of biogas should pay attention to the following problems.
It is strictly forbidden to throw various toxic pesticides, fungicides and other toxic substances or phosphorus-containing substances such as bone meal, animal corpses into the biogas digester in order to prevent the production of phosphine, a highly toxic gas which has serious harm to human body. When using biogas, it is strictly forbidden to play with fire around the mouth of the pond. If smelling bad eggs or finding air leakage in the room, the doors and windows should be opened quickly, the biogas should be discharged out of the room, and smoking, using open fire or switching power supply should be prohibited in order to prevent fire. It is strictly forbidden to use open fire to check the leakage of gas at the gas switch and joint. Do not test gas at the gas duct mouth of the gas, so as not to cause tempering and explosion.
Regular maintenance of digging and repairing of biogas digesters must be carried out by professionals. It is strictly forbidden for users of biogas to enter digging and repairing without authorization. Gas pipeline switches, joints and elbows are often detected with a brush dipped in laundry liquid or soapy water. The defective fittings are repaired or replaced in time after closing the main air switch. Always observe the change of water column of methane pressure gauge. When the methane digester produces gas vigorously and the pressure in the digester is too high, it is necessary to use gas, exhaust gas or extract part of material liquid from the discharging room immediately in order to prevent the expansion of the gas tank from breaking the lid of the digester and causing accidents. At the same time, keep the maintenance water of the movable cover of the biogas digester dry, so as to prevent the sealing clay of the movable cover from breaking and leaking, and poisoning livestock.
In case of fainting, people in the pool can not be rescued blindly. In the process of repairing, if they have headache, dizziness, nausea, vomiting or feel uncomfortable, they should leave the scene immediately. In case of fainting, fresh air should be conveyed to the pool by manual means immediately, so as not to be rescued blindly, so as to avoid a continuous suffocation poisoning accident. After the suffocation personnel rescue the pool in time, they should be lifted to the shady and ventilated place on the ground, unlock their jackets and trousers, pay attention to keeping warm, and send them to the nearest hospital for rescue.
