Description

The full condensation gas boiler of integral type three backhaul
Technical field
The utility model belongs to gas fired-boiler manufacturing technology field, is specifically related to the full condensation gas boiler of a kind of integral type three backhaul.
Background technology
Nearly ten years, energy structure in China there occurs huge change, due to the use of bunker coal, causes huge destruction to environment, and along with the transformation of national energy policy, natural gas will become the main energy sources of domestic heating.Tradition three backhaul natural gas boiler exhaust gas temperatures, at about 150 DEG C, fail to make full use of the latent heat of vaporization of water vapour in tail flue gas.Cause energy significant wastage, environmental protection needs energy-saving and emission-reduction, and important approach is exactly the full condensed natural gas boiler of Development of Novel.General condensed natural gas boiler increases economizer surface again after conventional natural gas boiler, there is floor space large, cause customer investment to increase, and line arrangement is also difficult.So need a kind of floor space little, and the natural gas boiler of full condensation can be reached.
Utility model content
The purpose of this utility model is to provide the backhaul of a kind of integral type three full condensation gas boiler, solves the problem that floor space is large, line arrangement is difficult that existing full condensation gas boiler exists.
The technical scheme that the utility model adopts is: the full condensation gas boiler of integral type three backhaul, comprise the first backhaul set gradually from top to bottom, second backhaul and the 3rd backhaul, described first backhaul is by corrugated internal furnace, return combustion chamber and explosion proof door connect to form successively, second backhaul is connected to form by threaded flue and front smoke box, 3rd backhaul is by connecting flue, energy-saving appliance and condenser connect to form successively, first backhaul and the second backhaul are arranged in cylindrical shell, the return combustion chamber of the first backhaul is communicated with the threaded flue of the second backhaul, the front smoke box of the second backhaul is communicated with the connection flue of the 3rd backhaul.
Feature of the present utility model is also:
Condenser is connected with exhanst gas outlet.
Cylindrical shell bottom is provided with bearing.
Energy-saving appliance, condenser adopts a point flow arrangement, and heating surface is provided with finned tube, and finned tube is staggered arrangement.
Explosion proof door adopts outlet structure.
The beneficial effects of the utility model are: the full condensation gas boiler of integral type three backhaul, take into full account flue gas cascade utilization principle, first backhaul adopts larger area corrugated internal furnace radiation-absorbing heat, second backhaul adopts the threaded flue adding strong disturbance to absorb high-temperature flue gas heat, 3rd backhaul adopts high efficient heat exchanging element to absorb low-temperature flue gas heat, and the water vapor condensation adopting resistant material heat exchange to make in flue gas, release the latent heat of vaporization.Drastically increase boiler thermal output like this, and integral structure makes boiler structure more reasonable, boiler floor space is less, and whole boiler manufacture cost does not increase.
Accompanying drawing explanation
Fig. 1 is the structural representation of the full condensation gas boiler of the utility model integral type three backhaul;
Fig. 2 is the side view of the full condensation gas boiler of the utility model integral type three backhaul.
In figure, 1. cylindrical shell, 2. corrugated internal furnace, 3. return combustion chamber, 4. threaded flue, 5. front smoke box, 6. connect flue, 7. energy-saving appliance, 8. condenser, 9. finned tube, 10. explosion proof door, 11. bearings, 12. exhanst gas outlets.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The full condensation gas boiler of integral type three backhaul as shown in Figures 1 and 2, comprise the first backhaul set gradually from top to bottom, second backhaul and the 3rd backhaul, first backhaul is by corrugated internal furnace 2, return combustion chamber 3 and explosion proof door 10 connect to form successively, second backhaul is connected to form successively by threaded flue 4 and front smoke box 5, 3rd backhaul is by connecting flue 6, energy-saving appliance 7 and condenser 8 connect to form successively, first backhaul and the second backhaul are arranged in cylindrical shell 1, the return combustion chamber 3 of the first backhaul is communicated with the threaded flue 4 of the second backhaul, the front smoke box 5 of the second backhaul is communicated with the connection flue 6 of the 3rd backhaul, condenser 8 is connected with exhanst gas outlet 12, cylindrical shell 1 bottom is provided with bearing 11, energy-saving appliance 7, condenser 8 adopts a point flow arrangement, heating surface is provided with finned tube 9, finned tube 9 is in staggered arrangement, explosion proof door 10 adopts outlet structure.
During use, flue gas enters from air inlet, and first through the first backhaul that corrugated internal furnace 2 and return combustion chamber 3 form, corrugated internal furnace 2 absorbs radiant heat; Then through the second backhaul that threaded flue 4 and front smoke box 5 form, now threaded flue 4 absorbs high-temperature flue gas heat; Flue gas enters energy-saving appliance 7 in the 3rd backhaul and condenser 8 by front smoke box 5 afterwards, and now, the finned tube on energy-saving appliance 7 and condenser 8 absorbs low-temperature flue gas heat.Last flue gas is discharged by exhanst gas outlet 12.
The full condensation gas boiler of the utility model integral type three backhaul, the finned tube that special return structures, energy-saving appliance and condenser are arranged, effectively can make the water vapor condensation in flue gas, releases the latent heat of vaporization.And the full condensation gas boiler structure of this integral type three backhaul is simple, and easy to operate, floor space is little, be easy to promote.
