Abstract

The utility model discloses a waste heat utilization stove, which relates to the technical field of stoves, the utility model comprises a chimney, a stove chamber and a stove shell, wherein, the periphery of a flue is provided with an interlayer containing the water, when the smoke which contains a large amount of waste heat and is generated after the combustion of the fuel in the stove chamber passes through the flue, the smoke can carry out the heat exchange with the water in the interlayer to change the water into the hot water. Compared with the prior art, the utility model solves the problem of the waste of the waste heat caused by the current existing stoves.

Description

The UTILIZATION OF VESIDUAL HEAT IN cooking stove

Technical field

The utility model relates to the kitchen range technical field, especially a kind of UTILIZATION OF VESIDUAL HEAT IN cooking stove.

Background technology

At present, widely usedly at home include chimney and burner hearth as the cooking stove of combustion medium with faggot and coal cinder, the subsidiary use device that has surplus heat, and for the firepower that produces when the fuel combustion not by too much the taking away of chimney, so the inlet of chimney flue is very short and little.Be single pot for cooking rice placed thereon, frying pan or kettle are heated in use, and the utilization rate of the heat energy that produces for combustion medium only is 10%～20%, all the other heats of 80%～90% all directly do not distribute from air or from chimney because there being residual heat using device, waste, and Civil energy-saving cooking stove also becomes genuine " tiger kitchen range ", thereby cause the huge waste of energy, the severe contamination of environment, and to the heavy damage of natural resources, the production and the life of returning the people have simultaneously caused great burden.

Summary of the invention

The UTILIZATION OF VESIDUAL HEAT IN cooking stove that the utility model provides, what it mainly solved is the problem that there is the waste heat waste in existing cooking stove.

In order to address the above problem, the scheme that the utility model adopts is: it includes chimney and burner hearth, be provided with the interlayer that is filled with water around its flue, when produce after the fuel combustion in burner hearth have a large amount of waste heat flue gases by flue the time and interlayer in water carry out heat exchange and make water become hot water.

In such scheme, in order to increase the area of heat exchange, in the endoporus of described chimney, can be provided with many staggered endothermic tubes, the interlayer UNICOM that is filled with water of this endothermic tube inner chamber and described chimney wall; Inwall at described chimney can be provided with the polylith buffler; Flue entrance the widest part of described chimney and the ratio at the narrowest place can for; In described chimney, can be equiped with the calandria heat exchanger

Owing to adopted such scheme, the utility model compared with prior art has following beneficial effect:

1, because it is provided with the interlayer that is filled with water around described flue, therefore, when people cook when preparing food in the burner hearth combust fuel, the flue gas that has the waste heat flue of promptly flowing through carries out heat exchange with water in the interlayer that is located at around the flue, heat in the flue gas is become hot water by the absorption of water, and heat energy is fully utilized, and has also removed the fuel consumption of heating up water from, saving at double fuel and time, alleviated people's labour intensity and economic spending.

2, because it is in the endoporus of described chimney, being provided with many is staggered and the endothermic tube of the interlayer UNICOM that is filled with water of its inner chamber and described chimney wall and be provided with the polylith buffler at the inwall of chimney, make the trend of flue gas the time be " Z " shape by flue, prolonged the time that the flue gas that has waste heat is detained in chimney, increased heat exchange area, make that waste heat can be by the more abundant absorption of the water in the interlayer, improve the afterheat utilization rate, when flue gas when the outlet of chimney is discharged, the heat energy that is had only is 10～20%, and remaining is all fully absorbed by the water in the interlayer.

3, because it is made as the inlet of the widest part greater than the thin-and-long of burner hearth upper end open the widest part to the inlet of flue, make more flue gas can flow to flue, and the inlet of thin-and-long can increase heat exchange area, the waste heat that makes flue gas in the porch by a large amount of absorbing.

The specific embodiment

Below in conjunction with the accompanying drawing example structure of the present utility model is described in further detail:

In the structure shown in the figure (1,2,3,4), burner hearth 1 of the present utility model adopts secondary air heat build-up insulation flue to surround, and the grate of installing in its underpart 2 is tower grates.Above burner hearth 1, be arranged with the following air draft flue 5 that constitutes by ring flat-plate 3 and cylindrical shell 4.Kitchen range shell 6 is mounted in down outside the secondary air passage of air exhaust passage 5 and secondary air heat build-up insulation flue, and like this, the flue gas that is produced when combustion fuel can flow in the flue of kitchen range shell 6 along following air draft flue 5.Kitchen range shell 6 is connected with chimney 7, is provided with the fire cover 10 that adapts with opening and pot shape above kitchen range shell 6.Be provided with the interlayer 11 that is filled with water around the flue of kitchen range shell 6, also be provided with the interlayer 12 that is filled with water at the flue of chimney 7, interlayer 12 links with interlayer 11.In the endoporus of chimney 7, be provided with many staggered endothermic tubes 8, the interlayer that is used to be filled with water 12 UNICOMs on the inner chamber of this endothermic tube 8 and chimney 7 walls.Inwall at chimney 7 also is provided with polylith buffler 9, make the trend of flue gas the time be " Z " shape by the chimney flue, so that prolong the holdup time of flue gas in chimney 7 that has waste heat, increase heat exchange area, waste heat can be absorbed more fully by the water in the interlayer.The flue entrance 13 of described chimney 7 is one thin-and-long inlet, and its widest part is 2: 40～8: 40 with the ratio at the narrowest place, and its widest part is greater than upper end open the widest part of burner hearth 1.The flue gas that such thin-and-long inlet is more conducive in the kitchen range shell flue flows into the chimney flue.Flue entrance 13 places at thin-and-long also are provided with the firepower catching sheet 14 that twice have the hole, are used for the firepower interception a pot body is absorbed fully, and waste heat also can flowing into the chimney flue uniformly through via hole around the pot body.

In the installation process of reality, as required, the not UNICOM of interlayer 12 that is filled with water of the be filled with water interlayer 11 and the chimney of kitchen range shell 6, independent respectively is installed on the existing Civil energy-saving cooking stove.Kitchen range shell 6 also can manufacture a chain of kitchen range and use.
