at present, biomass boiler generally adopts two kinds of mode of heatings, and one is the direct-type mode of heating, and namely the direct heated portion of boiler adopts the many backhaul designs of high-temperature flue gas, makes the heating surface area of boiler internal pipeline can reach maximum, two is the indirect type mode of heating, namely be provided with heat-exchanger rig at the boiler top, and with heat-exchanger rig and air-conditioning system, hot-water heating system directly is connected, and available technology adopting indirect type mode of heating, usually can be because of each pipeline compactness in heat-exchanger rig together, heating surface area is narrow, and cause the poor problem of heat transfer effect, and also exist heat-exchanger rig through after heat convection, owing to adopting iron pipe slowly to transmit, can cause the loss of heat in its process, wasted resource, when the hot water in boiler is applied to life by air-conditioning system and hot-water heating system again, adopt external heat exchanger tube, make heat energy loss large, and also need to increase an external plate and change water circulating pump, also caused certain electric energy loss.The utility model is called on and is being solved the problems of the technologies described above.
The utility model content
The purpose of this utility model is the problem of mentioning in the above-mentioned background technology in order to solve, and a kind of reasonable in design is provided, the heat-exchanger rig that is used for biomass boiler of good effect of heat exchange.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of heat-exchanger rig for biomass boiler, comprise inlet tube, outlet and heat exchanger tube, described heat exchanger tube is arranged on described boiler internal, described inlet tube, outlet run through respectively described boiler left side wall, right side wall, described heat exchanger tube is provided with at least two, be not in contact with one another between described every heat exchanger tube, also be arranged with muff on described outlet.
Further, can adopt spiral plate-like or bending-like between described heat exchanger tube, in the utility model, heat exchanger tube is set to spiral plate-like or bending-like, makes water and the energy of the hydro-thermal in boiler convective exchange time lengthening in heat exchanger tube, has improved the boiler hot exchange efficiency.
Preferably, described heat exchanger tube diameter is the 16mm left and right, and the distance of 6mm left and right at least of being separated by between described every heat exchanger tube, this arranges the water not only improved in copper tube and the thermal energy exchange speed of boiler hot gas, has guaranteed that also the temperature of water in the heat-exchanger rig outlet satisfies air-conditioning system and the requirement of the domestic water number of degrees.
Further, described muff inner face is glass fabric, is insulation surface outside described muff.
Further, described insulation surface is the glass fabric that scribbles layer of silica gel.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, the utility model heat-exchanger rig reasonable in design can make the heating surface area of heat exchanger tube reach maximum, has improved boiler steam thermal energy conversion efficiency.In the utility model by heat exchanger tube is arranged on boiler internal, and each heat exchange is not in contact with one another between changing, the steam in boiler can permeate in whole heat exchanger tube surrounding, make the interior water of heat exchanger tube and the steam in boiler that larger heat exchange contact area be arranged, improve widely the boiler hot exchange efficiency, thereby reduced the flue-gas temperature at boiler smoke outlet place.
2, in the utility model, the thermal losses of heat-exchanger rig outlet is lower, makes in transmitting procedure, avoids heat energy loss too much.In prior art, heat-exchanger rig outlet pipe end all adopts iron pipe to transmit slowly, without any Insulation, caused very large energy loss, be provided with muff in the utility model on the heat-exchanger rig outlet, this muff inner face adopts glass fabric, insulation surface is adopted in the outside, and insulation surface is the glass fabric that scribbles layer of silica gel, thereby the hot water in outlet has been taked Insulation effectively, has reduced the thermal losses in the outlet.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, during the below will describe embodiment, the accompanying drawing of required use is done to introduce simply, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the present embodiment;
Reference numeral: 1-heat-exchanger rig, 2-heat exchanger tube, 3-inlet tube, 4-outlet, 5-boiler, 6-muff.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
In conjunction with Fig. 1, a kind of heat-exchanger rig for biomass boiler, comprise inlet tube 3, outlet 4 and heat exchanger tube 2, this heat exchanger tube 2 is arranged on boiler 5 inside, this inlet tube 3, outlet 4 run through respectively boiler 5 left side walls, right side wall, and in addition, heat exchanger tube 2 is provided with at least two, and be not in contact with one another between every heat exchanger tube 2, also be arranged with muff 6 on outlet 4.
In the present embodiment, the heat exchanger tube 2 in heat-exchanger rig 1 is arranged on boiler 5 inside, this heat exchanger tube 2 is provided with two at least, in actual the setting, can select according to the boiler drum space size radical of heat exchanger tube.In the present embodiment, be not in contact with one another between each heat exchanger tube 2, make water and the steam in boiler 5 in heat exchanger tube 2 that the heat exchange contact area of maximum be arranged, greatly improved boiler 5 rates of heat exchange, thereby reduced the flue-gas temperature at boiler 5 exhaust opening places.
