Description

Gas fired-boiler flue gas waste heat recovery formula heating plant
Technical field
This utility model relates to a kind of flue gas waste heat recovery formula heating plant, belongs to energy-conservation recycling heating equipment field.
Background technology
In current heating system, generally use gas fired-boiler that the water in system is heated, the smoke evacuation of gas fired-boiler Temperature is 70-100 DEG C.In heating system, the general input water temperature of heat user that sets is as 70 DEG C, and outfan water temperature is 50 DEG C.For The water yield in guarantee system and hydraulic pressure, also can use water supply tank to supplement the water of loss in system, usual water supply tank be communicated to heat The outfan of user, the backwater together with heat user is co-flowed in gas fired-boiler.The temperature of the compensation water in replenishing water tank of water is The temperature of extraneous tap water, compensation water is heat user heat supply after gas fired-boiler is heated to design temperature.
Utility model content
The purpose of this utility model is to provide a kind of thermal efficiency height, the gas fired-boiler flue gas waste heat recovery formula of simple in construction Heating plant, utilizes fume afterheat to heat replenishing water tank of water, makes full use of the energy, reduce cost.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of gas fired-boiler flue gas waste heat recovery formula heating plant, including gas fired-boiler and heat user, gas fired-boiler defeated Going out end to be connected with the input of heat user, the outfan of heat user is communicated to the input of gas fired-boiler by circulating pump, also wraps Including the water supply tank being connected with heat user, the input of described water supply tank is connected with external source by inlet channel;Water supply tank Outfan be communicated in the pipeline between the outfan of heat user and circulating pump by moisturizing pipeline, the flue of gas fired-boiler lead to Crossing connecting tube to be connected with exhaust opening, described connecting tube installs and is arranged in water supply tank.
Being improved by of above-mentioned gas fired-boiler flue gas waste heat recovery formula heating plant, described connecting tube is corrugated tube.
Further improvement is that of above-mentioned gas fired-boiler flue gas waste heat recovery formula heating plant, described connecting tube arranges many Bar, is parallel to each other respectively and is arranged in juxtaposition in the inner chamber of water supply tank.
The beneficial effects of the utility model are:
Heating plant described in the utility model uses connecting tube connection flue and exhaust opening, and connecting tube passes water supply tank, profit With the compensation water in fume afterheat heating water supply tank, save fuel, reduce energy consumption.
Corrugated tube can effectively strengthen heat transfer effect as connecting tube, corrugated tube, improve the temperature of compensation water, save Boiler oil;Reduce exhaust gas temperature simultaneously, improve boiler thermal output.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model, and in figure, single lined arrows represents the flow direction of water;Double-lined arrow represents flue gas The flow direction.
In figure, each list of reference numerals is: 1, gas fired-boiler, 2, heat user, 3, water supply tank, 4, circulating pump, 5, flue, 6, moisturizing Pipeline, 7, inlet channel, 8, exhaust opening, 9, connecting tube, 10, sewage draining exit.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, a kind of gas fired-boiler flue gas waste heat recovery formula heating plant, including gas fired-boiler 1, heat user 2, follows Ring pump 4 and water supply tank 3.Described gas fired-boiler 1, heat user 2 and circulating pump 4 form heat supplying loop;Water supply tank 3 connects at circulating pump Before the input of 4, the water yield in heat supplying loop is supplemented.
The outfan of gas fired-boiler 1 is connected with the input of heat user 2, and the outfan of heat user 2 is communicated to circulating pump 4 Input, the outfan of circulating pump 4 is connected with the input of gas fired-boiler 1.I.e. by the backwater flowed out in heat user 2 through circulating pump The inflow gas fired-boiler 1 of 4 heats again, meets heat supply temperature requirement.Circulating pump 4 arranges two sets, uses a set of, another set of As standby.
The input of described water supply tank 3 is connected with external source by inlet channel 7;The outfan of water supply tank 3 arranges benefit Waterpipe 6, the end of moisturizing pipeline 6 is communicated in the pipeline between the outfan of heat user 2 and circulating pump 1.I.e. moisturizing pipeline 6 In compensation water finally flow into gas fired-boiler 1 through circulating pump 4.
One end of the flue 5 of gas fired-boiler 4 is connected with gas fired-boiler 4;The other end of flue 5 arranges connecting tube 9, connecting tube The other end of 9 is communicated to exhaust opening 8.Connecting tube 9 installs and is arranged in water supply tank 3.High-temperature flue gas in gas fired-boiler 4 is through cigarette When road 5 arrives in connecting tube 9, by heat exchange action, the compensation water in water supply tank 3 is heated by flue gas, promotes compensation water Temperature;Compensation water reduces the temperature of flue gas, energy efficient simultaneously, makes full use of fume afterheat.For improve flue gas delay time Between, strengthening heat exchange effect, described connecting tube 9 is corrugated tube, and connecting tube 9 arranges a plurality of, and be parallel to each other cloth arranged side by side respectively It is placed in the inner chamber of water supply tank 3.In the present embodiment, connecting tube 9 arranges two.
Sewage draining exit 10, easy cleaning is set in the lower end of the position that flue 5 is connected with connecting tube 9, flue 5.At sewage draining exit 10 Valve is set.
The foregoing is only preferred embodiment of the present utility model, all according to this utility model claim done equal Deng change and modification, covering scope of the present utility model all should be belonged to.
