The utility model discloses not only being favorable to the smooth and easy emission of flue gas comdenstion water in energy -saving appliance and the condenser, but also reaching the comdenstion water and do not spill from the flange between energy -saving appliance and condenser, condenser and the afterbody flue, this structure has still formed the flue gas water seal, has prevented that the flue gas from passing through the hydrophobic means atmospheric dilution, has simplified hydrophobic structural.
Description
Technical field
The utility model relates to a kind of boiler hydrophobic structure, specifically a kind of combustion natural gas boiler flue gas hydrophobic structure.
Background technique
Gas fired boiler is listed in one of upgrading products replacing coal-burned industrial boiler by country, gas fired boiler is mainly divided into fire tube gas fired boiler (WNS) and water pipe gas boiler (SZS, DHS), fire tube gas fired boiler (WNS) mostly is small-sized industrial boiler, its compact structure, do not exist leak out, the thermal efficiency high (its condenser boiler efficiency is higher than 100%), easy transportation and installation are quick.Water pipe gas boiler (SZS, DHS) mostly is medium-and-large-sized boiler, and burner hearth and back-end surfaces all adopt totally enclosed fin panel casing, have good airproof performance, the thermal efficiency high feature.Economizer and condenser are one of critical components of combustion natural gas boiler; because combustion natural gas boiler temperature of exhaust fume is lower than less than 70 DEG C; water vapour in flue gas can be a large amount of condensation; so installed flue gas steam trap connection additional on economizer and condenser; economizer and condenser is discharged, the object of protection safe operation of the boiler to reach condensed water.
But combustion natural gas boiler flue gas hydrophobic structure of the prior art is unfavorable for that condensed water discharges economizer and condenser smoothly, and economizer and condenser, adpting flange between condenser and back-end ductwork are immersed in condensed water, very easily make economizer and condenser, between condenser and back-end ductwork, joint often leaks, necessary blowing out when leaking, then sealing gasket is changed, formation vicious circle like this, and water-heating boiler is all generally for warming, the maintenance once leak, certainly will impact the heating of boiler.
Model utility content
For above-mentioned prior art Problems existing, the utility model provides a kind of combustion natural gas boiler flue gas hydrophobic structure, the smooth discharge of flue gas condensing water in economizer and condenser can not only be conducive to, and condensed water can also be reached not from economizer and condenser, adpting flange place between condenser and back-end ductwork spills, and can effectively prevent flue gas from entering air by steam trap connection simultaneously.
To achieve these goals, this combustion natural gas boiler flue gas hydrophobic structure comprises the economizer be connected with turning flue by adpting flange one;
Described economizer connects condenser by adpting flange two;
Described condenser connects back-end ductwork by adpting flange three;
The mid-rear portion of described economizer and condenser is respectively equipped with steam trap connection;
Described steam trap connection is communicated with drain nozzle, and is fixed by hydrophobic fixing device gusset;
Described economizer and the smoke entrance at condenser two ends are separately installed with the flap be connected with described steam trap connection.
Further, described drain nozzle is U-tube structure.
Further, the middle part of described condenser and rear portion are respectively equipped with steam trap connection.
Compared with prior art, this combustion natural gas boiler flue gas hydrophobic structure is not only conducive to the smooth discharge of flue gas condensing water in economizer and condenser, and condensed water can also be reached do not spill from economizer and condenser, adpting flange between condenser and back-end ductwork, this structure yet forms both flue gas water seal, prevent flue gas to enter air by steam trap connection, simplify hydrophobic structure.
Accompanying drawing explanation
Fig. 1 is agent structure schematic diagram of the present utility model;
Fig. 2 is the left view of Fig. 1;
In figure: 1, turning flue, 2, adpting flange one, 3, economizer, 3.1, flap, 3.2, hydrophobic fixing device gusset, 3.3, steam trap connection, 3.4, steel plate, 3.5, spiral fin coil, 4, adpting flange two, 5, condenser, 6, adpting flange three, 7, back-end ductwork, 8, drain nozzle.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As depicted in figs. 1 and 2, this combustion natural gas boiler flue gas hydrophobic structure comprises the economizer 3 be connected with turning flue 1 by adpting flange 1;
Described economizer 3 connects condenser 5 by adpting flange 24;
Described condenser 5 connects back-end ductwork 7 by adpting flange 36;
Described economizer 3 is respectively equipped with steam trap connection 3.3 with the mid-rear portion of condenser 5;
Described steam trap connection 3.3 is communicated with drain nozzle 8, and is fixed by hydrophobic fixing device gusset 3.2;
Described economizer 3 and the smoke entrance at condenser 5 two ends are separately installed with the flap 3.1 be connected with described steam trap connection 3.3, the structure of flap 3.1 is adopted to make the adpting flange 1 of turning flue 1 and economizer 3, the adpting flange 24 of economizer 3 and condenser 5, the position of the adpting flange 36 of condenser 5 and back-end ductwork 7 is all higher than steam trap connection 3.3, this structure is not only conducive to the smooth discharge of flue gas condensing water in economizer 3 and condenser 5, and condensed water can also be reached not from economizer 3 and condenser 5, adpting flange place between condenser 5 and back-end ductwork 7 spills.
Further, as shown in Figure 2, described drain nozzle 8 is U-tube structure.Can form water seal by the drain nozzle 8 of U-tube structure prevents flue gas from entering air by steam trap connection 3.3.
Further, as shown in Figure 1, because of the water that meeting condensation in condenser 5 is a large amount of, condenser 5 is hydrophobic for convenience, is respectively equipped with steam trap connection 3.3, to make not remaining condensed water in condenser 5 at the middle part of condenser 5 and rear portion.
This combustion natural gas boiler flue gas hydrophobic structure operationally, flue gas condensing water is pooled to steam trap connection 3.3 by flap 3.1, U-shaped drain nozzle 8 is connected with steam trap connection 3.3, condensed water discharges economizer 3 by steam trap connection 3.3 and U-shaped drain nozzle 8, condenser 5, condensed water is by forming flue gas water seal during U-shaped drain nozzle 8, be conducive to the smooth discharge of flue gas condensing water in economizer 3 and condenser 5, and condensed water can also be made not from economizer 3 and condenser 5, adpting flange place between condenser 5 and back-end ductwork 7 spills, can also prevent flue gas from entering air by steam trap connection 3.3.
In sum, this combustion natural gas boiler flue gas hydrophobic structure is not only conducive to the smooth discharge of flue gas condensing water in economizer and condenser, and condensed water can also be reached do not spill from economizer and condenser, adpting flange between condenser and back-end ductwork, this structure yet forms both flue gas water seal, prevent flue gas to enter air by steam trap connection, simplify hydrophobic structure.
