Abstract
The utility model provides a waste heat recovery system for a range hood, which comprises a hearth, the range hood and a heat preservation water tank, wherein the range hood is arranged right above the hearth; the waste heat recovery system further comprises a heat absorbing fin group including a plurality of heat absorbing fins connected in series end to end and arranged below a plurality of oil fume inlets of the range hood; the heat absorbing fins adopt winglike structures; the included angle between the width direction of the winglike structures and the horizontal plane is 45-90 degrees; the heat absorbing fin group is communicated with the heat preservation water tank through a plurality of pipelines to form a water circulation loop; at least one water pump is arranged on each pipeline; the water pump is used for providing power for circulation of water in the water circulation loop. The heat absorbing fins are vertically arranged below the oil fume inlets of the range hood, so that the flow smoothness of flue gas and better heat exchange efficiency are ensured while the heat exchange contact area is ensured.
Description
Technical field
The utility model relates to residual neat recovering system, particularly a kind of residual neat recovering system of smoke exhaust ventilator.
Background technology
At present, the waste heat of smoke exhaust ventilator is reclaimed, the waste heat that the kitchen range top is produced is used effectively and exists many technical problems.
Chinese patent (publication number CN203116195U) discloses a kind of flue gas waste heat recovery water heater, and flue gas waste heat recovery heat exchanger is installed above smoke exhaust ventilator, and matchmaker's outlet of flue gas waste heat recovery heat exchanger is communicated with boiler by heat pump type air conditioning system.The defect arranging is like this: fume afterheat can be escaped in a large number in the time of fan inspiration smoke exhaust ventilator on the one hand, and the top that heat transmission equipment is arranged to smoke exhaust ventilator can make heat exchange efficiency significantly reduce; On the other hand, heat exchanger is set in flue, because heat exchanger is made up of copper pipe etc. conventionally, in use easily be corroded, and in order to improve heat exchange efficiency, often require heat exchanger tube and flue gas to have larger contact area, be lowered with regard to the drafting efficiency that has caused smoke exhaust ventilator like this, make the one's work ability of smoke exhaust ventilator low.
Utility model content
The technical problems to be solved in the utility model is in order to overcome the defect that prior art heat exchange efficiency is low, drafting efficiency is low, provide the higher and flow of flue gas of a kind of heat exchange efficiency the residual neat recovering system of influenced less smoke exhaust ventilator.
The utility model is to solve above-mentioned technical problem by following technical proposals:
A kind of residual neat recovering system of smoke exhaust ventilator, it includes a kitchen range top, a smoke exhaust ventilator and an attemperater, described smoke exhaust ventilator be arranged at the described kitchen range top directly over, its feature is, the residual neat recovering system of described smoke exhaust ventilator also includes, one heat absorbing fins group, described heat absorbing fins group includes the heat absorbing fins that some head and the tail series connection are communicated with, and is arranged at the below of some oil smoke entrances of described smoke exhaust ventilator;
Described heat absorbing fins is the angle of cross direction and the horizontal plane wings between 45 °～90 °;
Described heat absorbing fins group is communicated with described attemperater and is formed a water-flow circuit by some pipelines;
On described pipeline, be provided with at least one water pump, described water pump is used to the circulation of the water in described water-flow circuit that power is provided.
Herein, owing to can consuming, escaping quite a few heat in the process of fan inspiration oil smoke, so heat absorbing fins is arranged to the upstream of fan, and by the angle of the heat absorbing fins cross direction of wings and horizontal plane between 45 °～90 °, when making heat absorbing fins keep flue gas circulation smooth as shutter, keep good heat exchange efficiency.
Preferably, on described attemperater, be provided with one for the water supplement port and that described attemperater carried out to moisturizing for exporting the hot water output port of hot water.
Herein, the hot water of output can be used as domestic hot-water.
Preferably, described heat absorbing fins is made up of Ni-based oxidation-resistant alloy.
Herein, Ni-based oxidation-resistant alloy has stronger oxidation resistance, and is applicable at high temperature working, and more traditional stainless steel or copper heat-exchanger rig heat conductivility are suitable.
Positive progressive effect of the present utility model is: by heat absorbing fins being vertically set in smoke exhaust ventilator oil smoke entrance below, in ensureing heat exchange contact area, both ensured that the smoothness of flow of flue gas had also ensured good heat exchange efficiency.

Owing to can consuming, escaping quite a few heat in the process of fan inspiration oil smoke, so heat absorbing fins is arranged to the upstream of fan, the namely below of oil smoke entrance 21, and by the angle of the heat absorbing fins cross direction of wings and horizontal plane between 45 °～90 °, when making heat absorbing fins keep flue gas circulation smooth as shutter, keep good heat exchange efficiency.
Heat absorbing fins group 1 is communicated with attemperater 5 and is formed a water-flow circuit by some pipelines.
On pipeline, be provided with water pump 3, water pump 3 is used to the circulation of the water in water-flow circuit that power is provided.
On attemperater 5, be provided with one for the water supplement port 51 and that attemperater 5 carried out to moisturizing for exporting the hot water output port 52 of hot water.
In addition, heat absorbing fins is made up of Ni-based oxidation-resistant alloy.
Although more than described detailed description of the invention of the present utility model, it will be understood by those of skill in the art that this only illustrates, protection domain of the present utility model is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these changes and amendment all fall into protection domain of the present utility model.
