Description

The twin flue environment-friendly energy-saving heating stove

Technical field

The utility model relates to the heating system field, is specifically related to a kind of twin flue environment-friendly energy-saving heating stove.

Background technology

In a lot of places, the weather in winter is colder.In order to resist severe cold, improve housing conditions, people just improve indoor temperature by various means.The equipment of existing heating usefulness has a variety of, comprises air-conditioning, heating system, heating stove etc.Air-conditioning and heating system heating effect are good, hygienic environment-protecting, but its expense is higher.And, because of electric power or the heating infrastructure perfect inadequately, its application also is restricted.The application of heating stove is more extensive, and is simple in structure based on fire coal, and it is convenient to install, use, and its use cost is lower, is subjected to the masses and welcomes.

Existing heating stove mainly comprises a shaft and a flue, and furnace body wall and walling of flue place are provided with the cooling water layer respectively.This water layer absorbs the heat in burner hearth and the flue, makes the water flow inside heat cycles.High-temperature water after the heating is circulated to outside heat abstractor from the delivery port of flue upper end, and the heat that the stove fuel combustion is produced takes indoor each position to, is the heating of whole room.Current temperature after the heat abstractor cooling reduces, and returns the shaft water layer from the water return outlet of restoration of lower stack, heats by the high temperature in the burner hearth, and circulation heats and so forth.Because this structure only heats recirculated water by furnace body wall and walling of flue, total calorific value that recirculated water absorbs is lower, and indoor temperature rise is restricted.In addition, because the hot-air in burner hearth and the flue is just directly discharged the open air by chimney under situation about fully not absorbed, Btu utilization efficient is low, and waste of fuel is serious.

Summary of the invention

The purpose of this utility model provides a kind of novel heating stove, the heat that burning produces fully can be absorbed, and take the position of respectively heating to recirculated water, thereby effectively improve indoor temperature, and and then possess efficient, energy-conservation effect.

For realizing this purpose, the scheme that the utility model adopts is, based on existing heating stove, sets up the centre water layer in flue, and it communicates with the flue water layer.

As the further embodiment of the utility model, flue wherein is set to rectangle, and middle water layer is isolated into two separate rectangular flues with flue, forms the twin flue structure.

The utility model also can be set up heating tube in shaft and combustion flue.

The beneficial effects of the utility model are: one, the setting of water layer and heating tube can promote the absorption of heat in shaft and the flue has been improved the thermal efficiency in the middle of the flue.Two, increased overall quantity of circulating water, made that the current in the outside heat abstractor can flow through with higher temperature, thereby effectively improve indoor temperature and heating area.Three, because flue gas mouth temperature reduces, and the burner hearth and the flue upper end temperature difference strengthen, and make the furnace air circulation accelerate, fuel combustion is complete, has tangible effect of coal saving.Four, because of the abundant burning of fuel, the utility model helps alleviating atmosphere pollution, has certain environmental-protection function.

Description of drawings

The utility model has three width of cloth accompanying drawings.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.

As shown in Figures 1 and 2, heating stove described in the utility model comprises shaft 1, flue 2, is provided with water layer 7,8 respectively in the furnace wall of shaft 1 and the wall place of flue 2, and water layer 7,8 connects mutually and becomes one.The lower end of shaft 1 is provided with water return outlet 3, and the upper end of flue 2 is provided with delivery port 4.

Fig. 1 represents the structural front view of a kind of embodiment of the present utility model.Wherein, flue 2 is a rectangle, and water layer 9 in the middle of these flue 2 inside are vertically arranged with communicates with the water layer 8 of flue 2, and its height is corresponding with the height of flue 2.Middle water layer 9 is isolated into two separate rectangular flues 11 with flue 2, forms the twin flue structure.As further scheme, Fig. 3 has represented the profile of present embodiment along the A-A direction.Longitudinally be respectively equipped with heating tube 10 in each independent flue 11, its concrete quantity can be determined according to the structure composition of structure, size and the shaft 1 of flue 2.In the present embodiment, be provided with four heating tubes 10 in each independent flue 11, it is respectively along the walling of flue setting.The upper and lower side of heating tube 10 communicates with water layer 8 or middle water layer 9.Heating tube 10 and middle water layer 9 can fully absorb the heat that the high temperature gas flow in the flue 2 carries, and recirculated water is heated, and promote water circulation, improve room temperature.In addition, it cools off the high temperature air in the flue 2, can reduce heat and scatter and disappear, and improves the thermal efficiency.Middle water layer 9 can have various forms when implementing, make flue form a kind of form of twin flue structure and be not limited to.For example, can be a kind of thin-walled raised structures that on the flue inwall, forms, or to the sandwich of the inner projection of flue etc., no matter which kind of form, as long as it can play the increase endotherm area, promote the effect of water circulation, all can reach the purpose of this utility model.

Fig. 2 represents the side sectional view of another preferred embodiment of the present utility model.In this scheme, be provided with heating tube 6 around burner hearth 5 in shaft 1, its two ends communicate with water layer 7 respectively, and its curved shape is corresponding with the shape of burner hearth 5, with the heat in the abundant absorption burner hearth.If burner hearth 5 is circular, also coiled circle of this heating tube then, if burner hearth 5 is square, then also coiled is square for this heating tube.The quantity of heating tube is determined according to the shaft concrete structure, generally can be 2～5 circles, and it is 3 circles that quantity is set in the present embodiment.Higher because of shaft 1 upper temp, the top that this heating tube 6 can suitably center on burner hearth 5 is provided with.Be vertically arranged with heating tube 9 in the wall of flue 2, its upper and lower side communicates with water layer 8 respectively.In addition, on the whole length of flue 2, also can be provided with a plurality of positions that communicate with water layer 8.
