Description
Technical field
The utility model relates to a kind of boiler exhaust gas treating apparatus, is specifically related to a kind of residual heat reclaiming apparatus for boiler vent gas.
Background technology
At present, the boiler on market is that fuel carrys out heating water with coal, thus reaches the object of heating.The heat utilization efficiency of general boiler is relatively low, and there are uneven, the problems such as air pollution is large to external world of being heated of smoke temperature too high waste energy, water, these all become the stumbling-block of construction of energy type society.Existing its complex structure of tail gas exhaust heat recovery, cost is higher, is not suitable for medium-sized and small enterprises and uses.Therefore, be necessary to solve the problem.
Utility model content
The purpose of this utility model is to provide a kind of residual heat reclaiming apparatus for boiler vent gas, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of residual heat reclaiming apparatus for boiler vent gas, comprise boiler and combustion chamber, be connected on the upside of described combustion chamber with smoke discharging pipe, described smoke discharging pipe and junction, combustion chamber are provided with smoke filters, and described smoke discharging pipe is connected with the water tank be positioned on the left of boiler; Be provided with coil pipe in water tank, coil pipe import is connected with smoke discharging pipe, and coil outlets is positioned at the opposite side of water tank, and is connected with harmful gas processing device, and described coil pipe is evenly provided with several fin; Also have two temperature sensors in described water tank, water tank is also provided with a heater for subsequent use be connected with water tank outward.
As further program of the utility model: described smoke filters is screen pack.
As the utility model further scheme: described fin is made up of aluminium alloy.
As the utility model further scheme: described fin is sheet.
The beneficial effects of the utility model are that structure is simple, and practicality is comparatively strong, can utilize fully the heat in smoke exhaust pipe, and the water in water tank absorbs the heat of tail gas, improves the temperature of water in water tank; When the shortage of heat in tail gas is to be heated to temperature required by the water in water tank, start heater for subsequent use, the water in water tank is heated to temperature required, ensure that the needs of enterprise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-boiler, 2-combustion chamber, 3-smoke filters, the import of 4-coil pipe, 5-heater for subsequent use, 6-temperature sensor, 7-harmful gas processing device, 8-coil outlets, 9-water tank, 10-coil pipe, 11-fin, 12-smoke discharging pipe.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of residual heat reclaiming apparatus for boiler vent gas, comprise boiler 1 and combustion chamber 2, be connected with smoke discharging pipe 12 on the upside of described combustion chamber 2, described smoke discharging pipe 12 is provided with smoke filters 3 with junction, combustion chamber 2, and described smoke discharging pipe 12 is connected with the water tank 9 be positioned on the left of boiler 1; Be provided with coil pipe 10 in water tank 9, coil pipe import 4 is connected with smoke discharging pipe 12, and coil outlets 8 is positioned at the opposite side of water tank 9, and is connected with harmful gas processing device 7, makes it possible to process the pernicious gas in flue gas, decreases environmental pollution.
Described coil pipe 10 is evenly provided with several fin 11, fin 11 increases the area of heat exchange, thus improves exchange efficiency.
Two temperature sensors 6 are also had in described water tank 9, water tank 9 is outer is also provided with a heater for subsequent use 5 be connected with water tank 9, when the shortage of heat in tail gas is to be heated to temperature required by the water of 9 li, water tank, start heater 5 for subsequent use, the water of 9 li, water tank is heated to temperature required, ensure that the needs of enterprise.
Described smoke filters 3 is screen pack.The bulky grain thing produced that burns in combustion chamber 2 is retained down by smoke filters 3, reduces the accumulation of ashes in coil pipe 10, prevents the blocking causing coil pipe 10.
Described fin 11 is made up of aluminium alloy.Described fin 11 is sheet.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
