Biogas generator set composition analysis and application power generation conditions

Composition analysis of biogas generator set and introduction of application power generation conditions

What is the composition of the biogas generator set? Many users are not very familiar with this aspect. The following is a detailed introduction made by the technical staff.

　　 1. Biogas desulfurization and pressure stabilization, explosion-proof equipment: The biogas used by the generator must first pass through the desulfurization equipment to reduce the corrosion of hydrogen sulfide to the generator. Equipped with a pressure stabilizing device on the biogas intake pipeline, so as to adjust the flow rate to achieve the best air-fuel ratio. In addition, in order to avoid backfire in the intake pipe, anti-backfire and explosion-proof equipment should be installed on the biogas main pipe.

　　2. Air intake conditioning system: On the intake manifold, an accurate and flexible gas mixer should be set up to adjust the mixing ratio of air and biogas.

3. Initiator incineration system: The incineration speed of biogas is slow. The incineration system of the original gas generator set using gasoline, diesel and natural gas should be modified to a certain degree to increase the incineration power, reduce the appearance of post-incineration, and extend the work. Lifespan.

　　4. Speed regulation system: If the biogas generator set works independently, that is, working with electrical equipment as the load, the incorporation and unloading of electrical equipment will shake the load of the generator. In order to ensure the normal operation of the generator set, the speed regulation system on the biogas generator is indispensable.

　　5. Preheating operation system: Select preheating operation equipment to use the heat in the cooling water and exhaust gas of the generator to improve the power utilization of biogas.

　　6. Grid-connected control system: It mainly includes generator voltage regulating circuit, active quasi-synchronous side-by-side control circuit, manual side-by-side wide biogas generator set and column control circuit, measurement circuit, gas generator and auxiliary equipment control circuit, etc.

　　 What are the conditions required for biogas power generation from landfills?

　　Before, garbage disposal was mainly handled by sanitary landfill. Landfills treated in this way will produce a large amount of landfill gas. If it is not treated or used, it will cause great air pollution to the surrounding environment and seriously affect the quality of life of nearby residents. Among them, landfill gas power generation is currently a major utilization method. What are the external conditions needed for biogas power generation from landfills?

　　1: The landfill must be sanitary landfill, which means that the anti-seepage film is used in the landfill process of the landfill

　　2: The waste in the landfill must be live waste from natural gas generators, and construction waste is certainly not acceptable.

3: The daily filling of domestic waste is more than 500 tons. Only this amount will produce a large amount of landfill gas. Otherwise, the small gas volume will affect the power generation and the rate of return on investment. If the gas volume is small, consider using a biogas incineration torch to incinerate these gases. .

　　4: The landfill time is at least three years, and the waste landfill is designed to be filled for more than 10 years.

　　5: If you want to use landfill gas to generate electricity on the Internet, you must also consider whether the nearest Internet site is too far away from the landfill. Too far is a huge investment.

　　Only meet the basic conditions of the above points, it is a meaningful consideration for whether to invest in a landfill. Of course, there are other factors that also affect landfill gas power generation.
