The evaporation cooling device is high in cooling efficiency, free of pollution on the environment, simple in structure and capable of effectively reducing temperature of the outer wall of the combustion chamber.
Description
Technical field
The utility model relates to a kind of firing chamber cooling unit, is specifically related to a kind of firing chamber evaporation-cooled device.
Background technique
The firing chamber is that fuel or propellant agent burn therein and generate the device of high-temperature fuel gas.It is widely used in fields such as motor or boiler.According to the difference of fuel, the firing chamber can be divided into: diesel combustion chamber, combustion of natural gas chamber, coal briquette firing chamber, biomass fuel combustion chamber etc.The firing chamber can produce great amount of heat in combustion process, this Security meeting to equipment produces fatal influence, and therefore cooling unit need be installed in most of firing chamber.
Firing chamber is in the market adopted water-cooled and air-cooled mode mostly.The former has relatively high expectations to the water yield, causes the waste of resource easily, nor enough environmental protection; The latter is a kind of type of cooling of cleaning, but because the problem of technology, its cooling effectiveness is not very desirable, has certain narrow limitation.
Evaporation cooling technique is to utilize the phase transition heat principle, and exchange capability of heat is strong; Medium has good electrical insulation properties and suitable boiling point; Adopt airtight self-circulation mode, system pressure is low, can regulate steam output automatically, is a kind of active type of cooling of environmental protection.
The model utility content
The purpose of the utility model is, a kind of firing chamber evaporation-cooled device is provided, and this device cooling effectiveness is high, and environmentally safe is simple in structure, can effectively reduce the temperature of outer wall of combustion chamber.
The purpose of the utility model realizes through following technical proposals: a kind of firing chamber evaporation-cooled device.Comprise: the firing chamber; High-temperature flame-proof wall outside the firing chamber; Annular space in the middle of the refractory walls, the condenser of top, firing chamber is installed on condenser inner cooling water inlet pipe and cooling water outlet pipe; The steam outlet pipe that connects condenser and annular space, the liquid inlet pipe of connection condenser and annular space sidewall.
In preferred embodiment of the utility model, said condenser is the tilting structure.
In preferred embodiment of the utility model, said insulation evaporative cooling medium must be realized gas-liquid conversion, the medium that density is less.
In preferred embodiment of the utility model, said steam outlet pipe should be positioned at the higher position of condenser.
In preferred embodiment of the utility model, said liquid inlet pipe should be positioned at the lower position of condenser.
In preferred embodiment of the utility model, said cooling water inlet pipe should be connected the flows outside water source with cooling water outlet pipe.
In preferred embodiment of the utility model, the fuel of said burner can be coal, diesel oil, rock gas or biomass fuel.
The utility model is compared than existing technology, has the following advantages and beneficial effect: the utility model provides a kind of firing chamber evaporation-cooled device, and this device cooling effectiveness is high, and environmentally safe is simple in structure, can effectively reduce the temperature of outer wall of combustion chamber.
Description of drawings
Fig. 1 is the whole cross-sectional view of the utility model.
The mark of each parts is following in the accompanying drawing: 1, firing chamber, 2, the high-temperature flame-proof wall, 3, the annular space, 4, the insulation evaporative cooling medium, 5, condenser, 6, steam outlet pipe, 7, liquid inlet pipe, 8, cooling water inlet pipe, 9, cooling water outlet pipe.
Embodiment
As shown in Figure 1, the utility model discloses a kind of firing chamber evaporation-cooled device.Comprise: firing chamber 1; High-temperature flame-proof wall 2 outside the firing chamber; Annular space 3 in the middle of the refractory walls, the condenser 5 of top, firing chamber is installed on condenser inner cooling water inlet pipe 8 and cooling water outlet pipe 9; The steam outlet pipe 6 that connects condenser and annular space, the liquid inlet pipe 7 of connection condenser and annular space sidewall.
A specific embodiment of the utility model is as shown in Figure 1, and the annular space 3 with in the middle of the insulation evaporative cooling medium 4 injection high-temperature flame-proof walls 2 can produce great amount of heat during 1 work of firing chamber; At this moment, insulation evaporative cooling medium between the annular space 34 becomes gaseous state by liquid state, and this gaseous state enters into condenser 5 from steam outlet pipe 6; Because the cooling water inlet pipe 8 in the condenser 5 is communicated with the mobile water source of outside with cooling water outlet pipe 9; Cooling water is entered from intake pipe 8, and the condenser 5 of flowing through spills out from outlet pipe 9 again; Reduced the temperature in the condenser 5 like this; Make insulation evaporative cooling medium 4 liquefies of steam state, because the effect of gravity, liquid medium flows to the liquid inlet pipe 7 of lower from the eminence of condenser 5; Flow back into through liquid inlet pipe 7 in the annular space 3 of high-temperature flame-proof wall 2, so just formed an airtight self-circulation system.
