Three, the content of utility model biogas combustion chamber

The purpose of this utility model:

The purpose of the utility model is to provide a kind of biogas combustion chamber, a large amount of heat of utilizing methane gas burning back to discharge, and after water vapor, the pushing turbine generating.Using marsh gas power generation, is that produce the second time of biogas ability again, can bring into play huger benefit.Make things convenient for industrial or agricultural, transportation production; And daily life.The harm of avoiding nuclear pollution to cause for the mankind and life on earth.Renewable, inexpensive, environmental protection, efficient, can practice thrift a large amount of non-renewable coal and petroleum resources.

The biogas combustion chamber is used for the biogas combustion power generation.The huge effect of natural energy source biogas can be given full play in this chamber, has increased considerably energy wealth, promotes social development.Particularly, substitute nuclear power station, reduce the nuclear crisis.

The technical scheme of the biogas combustion chamber that this utility model provides:

The combustion chamber that the utility model provides is characterized in that, this chamber is a cuboid, also can be designed to terrace with edge, round platform, and the body that makes up each other.Be arranged with elliptical cylinder-shape vaporization water pipe in the combustion chamber.Steam pushing turbine generating after the vaporization.If a combustion chamber can not be up to standard, can a plurality ofly link to each other the multistage combustion vaporization.

The waste gas that discharge the combustion chamber is rich in a large amount of heat, the cooling tower of flowing through cooling.Hot cooling fluid can supply to prepare natural pond liquid and be back to generating tube and vaporize.Requirement can not be reached like a cooling tower, the multistage cooling of a plurality of cooling towers can be passed through.

The vaporization water pipe of the elliptical cylinder-shape of laying in the combustion chamber can enlarge heating surface, impels gasification rate to accelerate.

Cooling tower is collected heat more than needed, recycle.

The brief introduction of biogas combustion chamber:

1. combustion chamber, moulding is cuboid or square, also can be designed to the solid of other shapes, like sphere, round platform, appearance such as terrace with edge, and the spatial modelling that combines each other by these solids.Its size is confirmed according to demand in practice.This chamber, its big I are built up long 8 meters, and wide 4 meters, other greater or lesser specifications also can be built up in high 5 meters combustion chamber.The bottom surface of each combustion chamber is provided with burner and combustion spray gun, and biogas and the air ratio in 1: 10 is evenly sprayed in the combustion chamber, makes it abundant burning, the generation heat.The gas that spray the bottom, its intensity differs.Also there is the secondary injection district both sides of wall.

Design pressure meter in the combustion chamber is surveyed the indoor pressure of meter at any time.

2. during the methane normal combustion, the highest temperature can reach 1200 ℃, and discharges great amount of heat energy.Under 1 cubic metre of biogas status of criterion, can discharge the heat of 17911-25075 kilojoule, roughly be equivalent to 0.7 kilogram of gasoline, or the heat that provides of 1 kilogram raw coal.

3. in the bottom of combustion chamber, the air-flow of the varying strength that ejects, the mist that intensity is high can make flame rising burning, at middle part and top flame are arranged all.Combustion front is arranged on the burner, the gas of injection a little less than, at base burning.In addition, for increasing the even effect of combustion of indoor flame, the suitable position of two walls rationally is provided with spray-hole before and after the combustion chamber, suitably sprays the varying strength mist, remedies the defective of indoor non-uniform combustion and combustion quantity not sufficient.

4. the natural pond oxygen gas mixture sprays into and wants evenly the combustion gas physical efficiency is spread apart.Cause gas when burning, strong and weak according to air-flow, limit diffusion, limit burning, and evenly burning.The vaporization water pipe is heated evenly.This just requires that higher requirement is arranged technically, reaches suitably, and is an amount of; Power, size is different.Sufficient combustion, calorific value reaches requirement, and indoor invariablenes pressure of liquid is in the certain numerical value scope.

5. the combustion chamber also will be provided with peep hole in many places, so that open observation ward's internal combustion situation at any time.

6. the hot-water line of discharging in the combustion chamber is claimed the vaporization water pipe.Be advisable with ellipse.Vaporization water pipe multilayer is interlaced arranging laterally.Can not stop up rising flame, can impel interior flame evenly to burn again, increase heating surface area.The generating tube of arranging, vertical upright with wide of this cylindroid cross section, towards locular wall, parallel with it.So not only should not stop up rising flame, simultaneously can also increase heating surface area, better absorb heat, quicken the vaporization of the aqueous solution, and when flame was risen, curve rose, and increases the utilization rate of heat.

7. do not reach the required effect of vaporization like a combustion chamber, can be connected a plurality of combustion chambers, increase vapourizing temperature step by step.With the circulating water pipeline that each chamber is connected, outer surface is provided with attemperator, prevents that the heat of vaporize water runs off.

8. the top, combustion chamber is a hemisphere, treats waste discharge gas in order to gathering.Under the hemispherical cover, be smoke evacuation wall with holes.Its effect is blocked the flame of combustion chamber internal combustion on the one hand, makes it abundant burning.Can get rid of the burning chamber waste gas rapidly on the other hand, reduce its pressure.

9. the appropriate design smokejack is wanted in the combustion chamber, guarantees that waste gas is unimpeded, reduces room pressure, and the accident that prevents takes place.Interior space part is the combustion zone, also is the vaporize water area under control that placement of multiple layers is arranged.Center, top, chamber is provided with main smokejack, and remainder is provided with a plurality of secondary smokejacks at rational position.Establish two or more shunting by-paths on the main smokejack, also will on this by-path, assist two exhaust pumps of major-minor are set.Naturally get rid of when smooth when main smokejack, can drive the major-minor exhaust pump according to situation and quicken exhaust, to reduce indoor pressure.In like manner, as required, on each secondary smokejack, also the major-minor exhaust pump can be set, auxiliary acceleration exhaust.Make the indoor safe pressure values that a constant scope is arranged, so that safety in production.

10. the combustion chamber internal layer is one deck flame retardant coating, and the centre is high pressure resistant steel construction, and skin is an overcoat.Between flame retardant coating and the steel construction, one deck insulating is arranged.Prevent that steel construction from reducing its voltage endurance capability because of being heated.Crisscross girder steel on steel construction, designed in some big-and-middle-sized combustion chambers, is connected each other between each girder steel, to strengthen combustion chamber compression strength and stability.

11. the red-hot gas of discharging from the major-minor smokejack, through cooling tower with its heat absorption.Hot water is waited until and is produced natural pond liquid usefulness, or refluxes and make the usefulness of vaporize water.

The beneficial effect of the utility model:

Impel biogas can bring into play bigger effect, efficient, energy-saving and environmental protection, valency are low, convenient, and practice thrift a large amount of fire coals and oil, make things convenient for industrial or agricultural and transportation production, and the people's life.Enhance productivity greatly, increase the wealth of society, promote social development.Prior, alternative nuclear power station generating reduces the nuclear crisis.
