At present, some areas of China utilize coal, oil, rock gas to generate electricity, but these resources are limited, and in power generation process, to give off harmful gases such as carbon dioxide, sulfur dioxide, the severe contamination air destroys ecotope, and the heat consumption height, the thermal efficiency is low.From the environmental protection and the angle that economizes on resources, national encourage growth hydroelectric power and wind-power electricity generation must have powerful water source drop but build the water power plant, limited by the geographical environment objective condition; Build the natural wind power station and need wind regime, but natural wind is generally unstable, generating efficiency is low, will be subjected to the restriction of regional condition equally.

A kind of wind energy power plant is arranged, comprise wind power generating set that wind turbine and generator constitute, make the wind tower, wherein communicate with ambient atmosphere by the air intake lane at the intracavity bottom of making the wind tower, wind turbine is arranged in the air intake lane, be provided with atomized water nozzle and the gas nozzle that links to each other with water pipe, tracheae respectively on the wind tower internal chamber wall making, the middle part of making wind tower inner chamber is provided with the heat tracing lid.The ignition device that this wind energy power station structure utilizes gas nozzle to carry is lighted rock gas, the air of making in the wind tower is heated, inside and outside making the wind tower, form the temperature difference, after being elevated to a certain degree, temperature opens the heat tracing lid, hot air in the tower rises at a high speed, the outer air of tower is then irritated into from the air intake lane at high speed and is replenished in the tower, and the wind turbine that air-flow promotes in the air intake lane rotates and the generating of drive generator set.But the hot air that this wind energy power plant produced scatters and disappears very fast, consumes greatly, and the heat energy utilization rate is lower; And it mainly is to be fuel with the rock gas, and cost is higher.

The model utility content

For solving above technical problem, it is main fuel with biogas that the purpose of this utility model is to provide a kind of, and the higher artificial thermo-electric generation station of heat energy utilization rate.

The technical solution of the utility model is as follows: a kind of artificial thermo-electric generation station, comprise the wind power generating set that wind turbine and generator constitute and make the wind tower, wherein wind power generating set is arranged in the air intake lane of making the wind tower bottom, the intracavity bottom of making the wind tower communicates with ambient atmosphere by this air intake lane, on the internal chamber wall of making the wind tower, be provided with the natural gas nozzle that is communicated with gas source, the top of making wind tower inner chamber is provided with the heat tracing lid, its key is: also be provided with return air mouth and biogas nozzle on the described internal chamber wall of making wind tower middle part, the biogas nozzle is positioned at the below of return air mouth and communicates with biomass pool by pipeline; Whorl is wound with the energy recovery pipe on the internal chamber wall of making the wind top of tower, and this energy recovery pipe is communicated with described return air mouth by being arranged at the backwind tube of making wind tower outer wall, is distributed with several through holes on the wall of energy recovery pipe.

The utility model utilizes biogas to replace the main fuel of rock gas of the prior art as heated air, the air of making in the wind tower is heated, the heat energy circulation makes makes the inside and outside temperature difference that forms of wind tower, drives the generator set generating thereby the wind turbine in the generation air-flow promotion air intake lane rotates.Biogas can place biomass pool to produce by municipal waste and mud.Because all there is rubbish and mud more than 300 tons every day in each cities and towns above county level, city, province city are more, 300 tons of rubbish and mud can be produced 1800 cubic metres biogas, the composite fertilizer that remaining bits can be produced ton surplus in the of 100 is supplied to vast farmers to be a farmer, both solved the municipal waste problem, increase the energy again, also supported agricultural production, belonged to an environmental protection conveyance system.

Owing to also contain a large amount of heat energy from making the air that wind tower upper end exhaust outlet goes out, the utility model is provided with the energy recovery pipe making on the wind top of tower internal chamber wall, it is recycling that the air that will contain heat energy is input to igniting place of making wind tower inner chamber, its loss part is replenished by the biogas burning in the heat energy cyclic process, has improved the utilization ratio of heat energy greatly.

Above-mentioned heat tracing lid is formed by two airtight box bodys butt joints, and the outer end of this box body is hinged with the inwall of making the wind tower, and the inner chamber of box body is connected to intake pipe and waste pipe respectively and draws and make outside the wind tower.

When making the wind generating, intake pipe connects cold water source, and cold water is constantly flowed in the box body, has both realized cooling, protective action to the heat tracing lid, can use to do him with the cold water heating after waste pipe flows out again.

Above-mentioned biomass pool be positioned at make the wind tower under.

Beneficial effect: the utility model makes full use of municipal waste and mud generation biogas is used for generating, has solved the treatment of urban garbage problem, has increased the energy, and the biogas bits can be used for production composite fertilizer, have supported agricultural production.Its used fuel is few, and heat energy utilization rate height can not cause environmental pollution; Make building of wind tower and not limited by geographical conditions, the use in power station is not subjected to seasonal effect yet, have addressing easily, little investment, advantages such as the construction period is short, cost is low, instant effect.
