Description

A kind of preheating type hot-water boiler
Technical field
It the utility model is related to hot-water boiler field, and in particular to a kind of preheating type hot-water boiler.
Background technology
Normal-pressure hot-water boiler, is also unpressurized hot water boiler, belongs to the category of domestic life boiler, and normal-pressure hot-water boiler is one Atmosphere entry is equipped with the top of kind, electrothermal atmospheric boiler boiler body is in the unpressurized hot water boiler of normal pressure operating status all the time, Its main feature is exactly boiler not pressure-bearing, without security risk, is mainly used for for warm production hot water.
In the prior art, the furnace body of the boiler is monolithic construction, mainly by monoblock type shell and its stove of interior setting Courage, has upper, middle and lower-ranking horizontal water tube in flue, the chimney above shell is connected through impact tube and formed with flue.It is this Recirculated water in boiler is to pass through the water storage room formed between shell and flue and the horizontal water tube connected with water storage room from bottom to top Circulated, its heating surface area is small, water capacity is larger, and consumption coal is more, and heating is slow.And the direct all-radiant furnace of combustion flame in combustion chamber Courage, after high-temperature flue gas flows up heating horizontal water tube, is directly entered chimney discharge, flue gas flow is short, and burning is not filled through impact tube Point, a big chunk heat is discharged with flue gas, its thermal efficiency is relatively low, and the flue-gas temperature being discharged is higher, causes the energy Waste.
Utility model content
The utility model aims to provide a kind of preheating type hot-water boiler, to improve the efficiency of utilization of boiler.
To achieve the above object, the technical solution of the utility model is as follows:
A kind of preheating type hot-water boiler, it is characterised in that:Heating flue including combustion chamber and combustion chamber, parcel Heat the water storage room of flue, the heat exchange mechanism being arranged on above water storage room;The heat exchange mechanism include more with heat exchanging water pipe, The moisturizing path and hot water outlet of heat exchanging water pipe's connection respectively;Described heating flue one end is also associated with smoke evacuation room, and smoke evacuation room connects Water preheating boiler is connected to, the flue of detour is provided with water preheating boiler, and is provided with multiple heat on flue pipe wall and hands over Change plate, multiple interlaced settings of heat exchanger plate.
Further, connect to form detour circuit two-by-two by elbow between the more heat exchanging water pipes, and finally connect To hot water outlet.
Further, the water preheating boiler water outlet is connected to moisturizing path by water pump.
Further, it is provided with flue gas emission passage at the top of the water preheating boiler.
Further, the water preheating boiler side is provided with into water passage.
The beneficial effects of the utility model are:Difference lies in increase for the utility model and traditional preheating type hot-water boiler Efficiency of utilization, the flue gas after burning is passed into water preheating boiler, flue gas preheats quilt in the flue gas air flue of detour It is a large amount of to absorb, and certain preheating is carried out, so as to improve efficiency of utilization.
Brief description of the drawings
Fig. 1 is preheating type hot water boiler structure schematic diagram provided by the utility model.
Marked in figure:1 it is combustion chamber, 2 be heating flue, 3 be water storage room, 4 be heat exchanging water pipe, 5 be smoke evacuation room, 6 is pre- Water heater, 7 be flue, 8 be moisturizing path, 9 be hot water outlet.
Embodiment
The utility model is described further with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of preheating type hot-water boiler, including combustion chamber 1, the heating flue 2 connected with combustion chamber 1, bag Wrap up in the water storage room 3 of heating flue 2, be arranged on the heat exchange mechanism of the top of water storage room 3;The heat exchange mechanism is included more with heat exchange Water pipe 4, heat exchanging water pipe 4 connects respectively moisturizing path 8 and hot water outlet 9;2 one end of the heating flue is also associated with smoke evacuation room 5, smoke evacuation room 5 is connected with water preheating boiler 6, and the flue 7 of detour is provided with water preheating boiler 6, and on 7 inner wall of flue It is provided with multiple heat exchanger plates, multiple interlaced settings of heat exchanger plate.
Connect to form detour circuit two-by-two by elbow between the more heat exchanging water pipes 4, and be eventually connected to hot water and go out Mouth 9.6 water outlet of water preheating boiler is connected to moisturizing path 8 by water pump.The top of water preheating boiler 6 is provided with flue gas row Put passage.6 side of water preheating boiler is provided with into water passage.
In actual use, the fuel in combustion chamber 1 largely burns, and to persistently inputting heat in heating flue 2, and A large amount of flue gas for containing and having surplus heat can be produced, flue gas is passed into water preheating boiler 6, and flue gas is in the flue gas air flue of detour Preheating is largely absorbed, and carries out certain preheating, so as to improve efficiency of utilization.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the present invention, for this For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model Within, any modification, equivalent replacement, improvement and so on, should be included within the scope of protection of this utility model.
