Description
Technical field
The present invention relates to biomass combustion machine field, particularly relate to a kind of biomass combustion machine that has evaporation-cooled device.
Background technology
Owing to behind the biomass combustion, can produce the temperature that is close to more than thousand degree, therefore, can bear high temperature in order to make combustion furnace; Increase the service life of combustion furnace, generally all can be at outside wall surface parcel one deck fire-resistant heat insulating material of combustion furnace, like brick material or sheet material, still; These fireclay insulating refractories still can be too high because of temperature under the situation of bearing high temperature for a long time, and the disappearance of be full of cracks, damage is arranged; And must regularly replace, cause puzzlement and inconvenience in the use and the waste that causes resource.
Therefore, in order to reach better cooling effect of heat insulation, often outside fire-resistant heat insulating material, set up cooling device again; At present the biomass combustion machine uses is mainly water cooling mode and air cooling mode, and the advantage of water-cooling apparatus is good cooling results, refrigerating efficiency height, and the initial stage input cost is lower; Be applicable to medium-and-large-sized refrigeration system; But this device can cause the waste of great lot of water resources, and needs to install water circuit system and water system etc. in the device, and structure is comparatively complicated; Air-cooling apparatus is for water-cooling apparatus; Structure is comparatively simple, can not cause a large amount of wastes of resource, still; Because the thermal conductivity far of air is lower than the thermal conductivity of water; This will certainly make lower that its heat transfer coefficient falls, so the required heat transfer area of air cooler is than big many of water-cooled under identical thermic load, so the investment cost of air-cooling apparatus generally is more than 2～3 times of water cooler.
Summary of the invention
The technical problem that the present invention mainly solves is: resource is wasted in a large number in the above-mentioned solutions for refrigeration, refrigerating efficiency is not high and the problem of refrigeration plant expensive.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of biomass combustion machine that has evaporation-cooled device is provided, comprises: cylindrical shell, air blast and combustion chamber, and said combustion chamber is in barrel; Said air blast is arranged on the cylindrical shell; Be evaporimeter between said cylindrical shell and the combustion chamber, be filled with evaporative cooling medium in the said evaporimeter, said medium is close to outer wall of combustion chamber and is full of whole evaporimeter; Said cylindrical shell top is provided with condenser, passes through pipeline connection between said evaporimeter and the condenser.
In preferred embodiment of the present invention, said pipeline is gas flow tube and return duct, and said evaporimeter gets into condenser through gas flow tube earlier, cools off after return duct is got back to evaporimeter through condenser.
In preferred embodiment of the present invention, the inside of said condenser is cooling cast or fin type.
In preferred embodiment of the present invention, said condenser outer walls lower end and return duct junction are provided with a groove.
In preferred embodiment of the present invention, said cooling medium circulation can provide circulation power or not have the pump self-loopa by pump.
In preferred embodiment of the present invention, said outer wall of combustion chamber scribbles heat insulation, the high-temperature refractory of one deck.
The invention has the beneficial effects as follows: the present invention provides a kind of biomass combustion machine that has evaporation-cooled device; Can effectively reduce the temperature of outer wall of combustion chamber; And can promote the service life and the safety in utilization of biomass combustion machine combustion chamber effectively, and simple in structure, investment cost is lower, stronger practicality is arranged.
Description of drawings
Fig. 1 is the structural representation that the present invention has the biomass combustion machine-preferred embodiment of evaporation-cooled device;
The mark of each parts is following in the accompanying drawing: 1, cylindrical shell, 2, the combustion chamber, 21, outer wall of combustion chamber, 22, heat resistant fireproof material, 3, evaporimeter, 31, evaporative cooling medium, 32, gas flow tube, 33, return duct, 4, air blast, 5, condenser, 51, groove.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1; The embodiment of the invention comprises: cylindrical shell 1, air blast 4, combustion chamber 2, evaporimeter 3 and condenser 5; Combustion chamber 2 is in cylindrical shell 1 inside; Air blast 4 is arranged on the cylindrical shell 1 and with combustion chamber 2 and communicates, and makes that the living beings in the combustion chamber 2 can be burnt fully under the situation of air abundance, thereby produces the flame that has high temperature.
Combustion chamber 2 outer walls scribble heat insulation, the high-temperature refractory 22 of one deck brick material or sheet material, have improved the security that use the combustion chamber.
Be evaporimeter 3 between cylindrical shell 1 and the combustion chamber 2, be filled with insulation evaporative cooling medium 31 in the evaporimeter 3, medium 31 is close to combustion chamber 2 outer walls and is full of whole evaporimeter 3, makes evaporative cooling medium 31 fully absorb the heat in the combustion chamber 2.There is condenser 5 on top at cylindrical shell 1 through pipeline connection, has constituted totally enclosed cooling recirculation system thus.
Connecting pipeline between cylindrical shell 1 and the condenser 5 is gas flow tube 32 and return duct 33.When start working in combustion chamber 2,31 of evaporative cooling mediums begin to absorb heat, begin to vaporize when reaching the boiling point of medium 31 itself, rise also through gas flow tube 32 entering condensers 5.Cast or fin type can be selected to cool off in the inside of condenser 5; When selecting the cooling cast, establish horizontal U-shaped circulation passage pipe in the condenser 5, the upper end is the cooling water water inlet end; The lower end is the cooling water water side, and the cooling water of inflow is with getting into evaporimeter 3 through the return duct circulation after the steam cooled; When selecting fin type, fin is arranged in the condenser 5, and gas flow tube 32 is passed a plurality of fin and is connected with return duct 33, thereby ascending air is cooled off rapidly.Condenser 5 outer wall lower ends and return duct 33 junctions are provided with a groove 51, make the cooled liquid of air-flow flow into return duct 33.Directly effectively take away the heat of outer wall of combustion chamber 21 through this cooling recirculation system, made the temperature of outer wall of combustion chamber 21 depend on the evaporating temperature of the evaporative cooling medium 31 that insulate.
Be different from prior art; The combustion chamber cooling technology of biomass combustion machine of the present invention adopts evaporation cooling technique; Solved high problem and the water cooling mode wasting of resources and the baroque problem of investment cost of existing air cooling mode; Can effectively reduce the temperature of outer wall of combustion chamber 21, and can promote the service life and the safety in utilization of biomass combustion machine combustion chamber 2 effectively, and simple in structure, investment cost is lower, stronger practicality is arranged.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
