Description

Electricity starts miniature household biogas electricity generating device

Technical field

The utility model relates to a kind of electricity generating device, and especially a kind of electricity starts miniature household biogas electricity generating device.

Background technique

In the application of existing biogas technology, it mainly is as drink thing fuel and illumination, especially in spring, summer, Qiu Sanji, under the high situation of ambient temperature, the natural pond that produces under the multiple situation is large-minded and too many or too much for use, the high biogas air delivering pipeline that damages easily of biomass pool air pressure, and zymotic fluid in the pond is directly extruded outside the pond from water pressure chamber, and sewage flows everywhere, so just often directly be put into the biogas of producing the atmosphere between air storage, so both waste the gas resource, polluted air again.

The model utility content

The purpose of this utility model provides a kind of electricity and starts the miniature marsh gas power generation device of four-stroke, can obtain the combustible gas that the fermentation of small-sized methane pond, rural area produces to utilize, and also can solve the electrical problem of non-Electric region and the economize on electricity problem of electric region simultaneously.

The technical solution of the utility model is: a kind of electricity starts miniature household biogas electricity generating device, comprise air feeder and electricity generating device, actuating motor is housed on electricity generating device, electricity generating device is made up of motor and generator, between air feeder and electricity generating device, be provided with the methane voltage-stabilizing device, this methane voltage-stabilizing device is made up of biogas controlling mechanism and biogas mixed organization, the biogas controlling mechanism comprises expansion box and Air-regulating valves, the expansion box inner route clapboard is divided into, following two chambers, with dividing plate that the gas storage tank wall contacts on have the regulating the qi flowing in the channels hole adaptive with Air-regulating valves, have the suction port that is communicated with air feeder at the expansion box cavity of resorption, the biogas mixed organization comprises gas-air mixing chamber and pressure automatic valve, at gas-air mixing chamber top air-strainer is housed, pressure automatic valve couples together expansion box epicoele and gas-air mixing chamber, and gas-air mixing chamber bottom is communicated with the firing chamber of motor by pipeline.

The utility model proposes and the matching used miniature marsh gas power generation device in small-sized methane pond, rural area, can obtain unnecessary combustible gas utilizing, also can solve simultaneously the electrical problem of non-Electric region and the economize on electricity problem of electric region, along with future biogas further popularize, vast rural area will substitute conventional energy resource with the electric power that biogas sends, it is significant to the consumption that reduces China's thermal power generation construction number and coal, can produce remarkable economic efficiency and social benefit.At present each Thermal Power Station of country will invest several hundred million yuan, and floor space is big, and water resource waste is big, and befouling environment, and it mainly consumes a large amount of coal resources simultaneously, and economy and Environmental costs that every kilowatt-hour is paid are higher.Most importantly, remote power delivery line construction and transmission of electricity transformation system expense costliness, and the remote electrical loss of carrying of electric power is very big, has caused energy waste.

If with the self-supporting electricity generating device of rural area household biogas, from peasant self, cost of electricity-generating is low, saved expense, considered that from the national interests overall situation it has saved energy resources, reduced the investment of coal-fired thermal power factory, this project is very important, and has very big actual application value.

The household biogas generating; its customer volume is big; its amount of electricity saving is big; when having 200,000,000 peasant familys, China have 40% user to adopt the self-supporting generating of biogas; 8,000 ten thousand families; each household one day is with 1 degree; 8,000 ten thousand degree electricity are just arranged, and each household was sent out 7 degree electricity in one day, just with 56,000 ten thousand degree; this numeral is very surprising; it can make us build tens of the Thermal Power Stations of 1,200,000 KW/h less, save tens construction fund, save the up to ten million tons of coal; utilize renewable energy sources marsh gas power generation, for the energy security and the environmental protection of country provides strong assurance.

Fig. 1 is the utility model structural representation.

Embodiment

The utility model structure is as shown in Figure 1: comprise air feeder and electricity generating device, air feeder comprises biomass pool 1, gas holder 2 and balancing weight 3, actuating motor 16 is housed on electricity generating device, electricity generating device is made up of motor 14 and generator 15, between air feeder and electricity generating device, be provided with the methane voltage-stabilizing device, this methane voltage-stabilizing device is made up of biogas controlling mechanism and biogas mixed organization, the biogas controlling mechanism comprises expansion box and Air-regulating valves, expansion box inner route clapboard 7 is divided into, following two

chambers

8,6, with dividing plate that the gas storage tank wall contacts on have the regulating the qi flowing in the channels hole 9 adaptive with Air-regulating valves 17, regulate pressure in the expansion box by Air-regulating valves 7, have the suction port that is communicated with air feeder and be communicated with gas holder 2 on the air feeder at expansion box cavity of resorption 6 by the air supply pipe 4 of band electromagnetic valve of gas circuit 5, the biogas mixed organization comprises gas-air mixing chamber 10 and pressure automatic valve 11, at gas-air mixing chamber top air-strainer 12 is housed, pressure automatic valve 11 couples together expansion box epicoele 8 and gas-air mixing chamber 10, and gas-air mixing chamber 10 bottoms are communicated with the firing chamber of motor by pipeline 13.
