Description
Technical Field
The utility model belongs to the field of resource utilization and environmental protection, in particular to a clear water compressed air methane tank.
Background
Biogas: the combustible gas is generated by organic substances through microbial fermentation under the conditions of certain temperature, humidity and pH value in an anaerobic environment. This gas is called biogas because it is originally found in swamps, lakes, ponds. Biogas is a mixed gas, the main component of which is methane, and the secondary components are carbon dioxide and hydrogen sulfide (H)2S), ammonia, and other components. In the composition of the biogas, combustible components comprise methane, hydrogen sulfide, carbon monoxide, heavy hydrocarbon and other gases; the non-combustible components include gases such as carbon dioxide, nitrogen and ammonia.
The existing hydraulic methane tank mainly comprises a feeding pipe, a tank body, a discharging pipe, a discharging chamber and an air guide pipe, wherein the lower half part of the tank body is a fermentation chamber, the upper half part of the tank body is an air storage chamber, and the fermentation chamber and the air storage chamber are mixed into a whole without an interface. The working principle is as follows: when gas is produced, the liquid level of the discharged material is raised by the gradually increased methane pressing liquid, and the liquid level difference is formed between the liquid level of the discharged material and the liquid level in the tank so as to maintain the balance of the internal pressure and the external pressure. When the user uses the methane, the air pressure in the pool is reduced, and the feed liquid in the discharging room is pressed back to the fermentation room to maintain the new balance of the internal and external pressure. Therefore, gas production and gas utilization are carried out continuously, so that the liquid level of the fermentation chamber and the liquid level of the discharging chamber are lifted continuously, and the pressure balance state is maintained all the time. The gas generation and the gas utilization work circularly, and the air pressure of the gas chamber is automatically adjusted by the automatic lifting of the material liquid in the discharging chamber, thereby ensuring the stable firepower of the combustion furnace. However, the methane generated by the feed liquid in the discharging room is directly discharged, which wastes methane resources and pollutes the environment.
