Abstract

The utility model discloses a system for recycling waste heat of a boiler, which is characterized in that the system comprises a smoke conveying pipe, a waste heat recycling device and a chimney, wherein a draught fan is arranged between the chimney and the waste heat recycling device, high temperature smoke exhausted by the boiler is discharged by the chimney through a smoke conveying pipe and the waste heat recycling device under the action of the draught fan, the waste heat recycling device is provided with a cold water inlet pipe and a hot water outlet pipe which is connected with a heat preservation hot water tank through a pipeline, and the pipeline of the cold water inlet pipe is also provided with a circulation water pump. The system has the beneficial effects of simple structure and high recycling rate. The high temperature smoke and the heat of water are exchanged through the waste heat recycling device, so that a large quantity of heat energy is transmitted to the water so as to raise the water temperature, the heat quantity of the high temperature smoke is recycled, so that the resource waste is reduced.

Description

The boiler afterheat recovery system
Technical field
The utility model relates to field of energy-saving technology, especially a kind of boiler afterheat recovery system.
Background technology
At present, for boiler, no matter be coal-burning boiler, gas fired-boiler or oil burning boiler; All have the lower problem of the thermal efficiency, wherein, flue gas loss is a maximum loss of boiler thermal output; Great amount of heat energy along with fume emission in atmosphere and slattern, also have waste-heat recovery device at present, but there is the shortcoming of recovering effect difference in it; And indivedual good waste-heat recovery devices of recovering effect are but promoted because of its complex structure, high being difficult to of cost.
Summary of the invention
The basic task of the utility model provides a kind of simple in structure, boiler afterheat recovery system that recovering effect is good.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: boiler afterheat reclaims heating system; It is characterized in that: this boiler afterheat reclaims heating system and comprises defeated smoke pipe, waste-heat recovery device and smoke evacuation chimney; Between smoke evacuation chimney and waste-heat recovery device, be provided with the defeated smoke pipe of high-temperature flue gas warp, waste-heat recovery device that boiler is discharged; Air-introduced machine by the smoke evacuation chimney discharge; Cold water inlet tube and hot water outlet pipe are installed on the waste-heat recovery device, and the hot water outlet pipe links to each other with a heat preservation hot water tank through pipeline, on the pipeline of cold water inlet tube, also is provided with a water circulating pump.
Said waste-heat recovery device is an air source heat pump hot-water heating system.
Between said defeated smoke pipe and smoke evacuation chimney, be provided with the bypass wind conveying pipe, respectively be provided with an air-valve on said defeated smoke pipe, smoke evacuation chimney and the bypass wind conveying pipe.
The beneficial effect of the utility model is: have advantage simple in structure, that the rate of recovery is high.
Through waste-heat recovery device, with high-temperature flue gas and hydrothermal exchange, a large amount of thermal energy transfer feedwater heats up water, and the heat of high-temperature flue gas is recycled, and reduces the wasting of resources.
Bypass airduct and air-valve are set; When the water of heat preservation hot water tank is expired; Open the air-valve of bypass wind conveying pipe, make high-temperature flue gas from the bypass wind conveying pipe, through the smoke evacuation chimney discharge, waste-heat recovery device quits work; Close the air-valve of defeated smoke pipe and smoke evacuation chimney, energy savings and avoid equipment to work long hours and reduce the life-span.
Description of drawings
Fig. 1 is the system block diagram of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model done further being described in detail.
As shown in Figure 1; Boiler afterheat reclaims heating system; Comprise defeated smoke pipe 1, waste-heat recovery device 2 and smoke evacuation chimney 3, between smoke evacuation chimney 3 and waste-heat recovery device 2, be provided with air-introduced machine 4, act on the defeated smoke pipe 1 of high-temperature flue gas warp, the waste-heat recovery device 2 that the fire grate of cooking goes out at air-introduced machine 4; Discharge by smoke evacuation chimney 3; Cold water inlet tube and hot water outlet pipe are installed on the waste-heat recovery device 2, and the hot water outlet pipe links to each other with a heat preservation hot water tank 5 through pipeline, on the pipeline of cold water inlet tube, also is provided with a water circulating pump 6.
Waste-heat recovery device 2 is an air source heat pump hot-water heating system in the present embodiment.
Between defeated smoke pipe 1 and smoke evacuation chimney 3, be provided with bypass wind conveying pipe 7, respectively be provided with an air-valve 8 on defeated smoke pipe 1, smoke evacuation chimney 3 and the bypass wind conveying pipe 7.
For improving the stability of system, the utility model also is provided with the reserve pump of water circulating pump 6, prepares against use when water circulating pump 6 breaks down, and does not influence the operate as normal of whole system.
The operation principle of the utility model is: under the effect of air-introduced machine 4; The high-temperature flue gas that boiler produces is through defeated smoke pipe 1;, discharge through smoke evacuation chimney 3 again, and waste-heat recovery device heats up water the heat that absorbs the part heat absorption through waste-heat recovery device 2; Finally be kept in the heat preservation hot water tank 5, supply and demand wants the user of hot water to use.When the water of heat preservation hot water tank is expired, open the air-valve of bypass wind conveying pipe, make high-temperature flue gas from the bypass wind conveying pipe, through the smoke evacuation chimney discharge, waste-heat recovery device then quits work.
Should be noted that at last; Above content is only in order to explain the technical scheme of the utility model; But not to the restriction of the utility model protection domain; The simple modification that those of ordinary skill in the art carries out the technical scheme of the utility model perhaps is equal to replacement, does not all break away from the essence and the scope of the utility model technical scheme.
