Abstract
The utility model relates to a blast type top heating water heating furnace. A furnace body is composed of an upper seal head, a lower seal head and a cylindrical casing body which are vertically arranged along the axial line thereof. A water inlet is arranged on the lower part of the casing body, and a water outlet is arranged on the center of the top of the upper seal head. A combustion chamber which is provided with a gas jet head and an ignitor in the interior is arranged on the upper position of an inner cavity of the furnace body, and a gas inlet pipe on the upper part of the casing body is communicated with the combustion chamber. A pipeline which is used for heat exchange and is communicated with the combustion chamber is used as a heat pipe, and the heat pipe spirals downwards in a spiral mode and is connected with a gas outlet pipe on the lower part of the casing body. The utility model reduces heat loss of the furnace body wall and the combustion for environment, lowers exhaust emission temperature and improves heat efficiency.
Description
The utility model relates to heat exchanger, makes the field in particular for producing life with the heat exchanger of hot water.
The existing water heater of life that provide with hot water, comprise body of heater (mainly forming) by upper and lower end socket and garden tubular shell, place the combustion chamber (in be provided with gas spray head and igniter or directly burn coal) of body of heater inner chamber bottom, place the body of heater inner chamber, be used for the pipeline of heat exchange, and the entery and delivery port and the combustion gas import and export pipe of relative set on the body of heater.It adopts the shell and tube heat exchange mode, cold medium---cold water is in pipe, thermal medium---combustion gas is outside pipe, between pipe, thermal medium is from bottom to top discharged from flue after heat exchange, and its exhaust temperature is up to 200 ℃, and all there are the heat loss phenomenon in body of heater wall and combustion chamber, therefore, the thermal efficiency is very low, and a large amount of heat energy have been wasted in vain.
Task of the present utility model is to overcome above weak point and heat hot water stove on a kind of blowing-type is provided, and its thermal loss is little, has the higher thermal efficiency.
Task of the present utility model is realized by following design: heat hot water stove on a kind of blowing-type, mainly by upper and lower end socket, the body of heater that the garden tubular shell is formed, be arranged on entery and delivery port and combustion gas import and export pipe on the body of heater, inside is provided with the combustion chamber of gas spray head and igniter, and the pipeline that place the body of heater inner chamber, is used for heat exchange is formed; This body of heater vertically is provided with by its axis; This combustion chamber is arranged on body of heater inner chamber top position, and the fuel gas inlet pipe that is arranged on housing top is connected with this combustion chamber; The above-mentioned pipeline that is used for heat exchange is connected with the combustion chamber, and for the combustion gas circulation, this heat pipe spirals downwards by spiral way, until being connected with the gas outlet pipe that is arranged on lower housing portion as heat pipe; Above-mentioned water inlet is arranged on lower housing portion, and above-mentioned delivery port is arranged on the upper cover center of top.
Adopt as above design, under situation by the inside air blast in fuel gas inlet pipe place, combustion gas (as natural gas, coal gas etc.) is in combustion chambers burn, and flows in the pipeline that is provided with downwards that spirals by spiral way, after the gas outlet pipe of lower housing portion discharge, meanwhile, cold water enters body of heater through the water inlet of lower housing portion, outside pipe, between pipe, flows, and through whole combustion chamber outer surface, after the delivery port on the upper cover, becoming hot water outwards provides.The utility model characteristics are, one, with thermal medium in that pipe is outer, heat exchange mode is compared between pipe, thermal medium (combustion gas) is in pipe, cold medium (cold water) is outside pipe, between pipe and the injection inboard wall of furnace body, this has just been avoided the heat loss of body of heater wall to external environment; Its two, under the identical situation of body of heater height, compare with the shell and tube heat exchange mode, the heat pipe that spiral way is spiraled and is provided with downwards, the passage of its combustion gas can be longer, thereby the exhaust temperature of its combustion gas tail gas is minimized, the thermal efficiency is improved; Its three, whole combustion chamber is fully immersed in the cold medium, the heat energy of fuel gas buring can not scatter and disappear, and has stopped the phenomenon of the heat-energy losses that the combustion chamber part of aforementioned existing water heater exists.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the vertical view (removing upper cover) of an embodiment of the utility model;
Fig. 2 is the cutaway view along the A-A line shown in Figure 1;
Fig. 3 is the schematic perspective view of heat pipe shown in Figure 1;
Fig. 4 is the vertical view (removing upper cover) of another embodiment of the utility model;
Fig. 5 is the schematic perspective view of heat pipe shown in Figure 4.
Fig. 1 and Fig. 2 illustrate, body of heater is mainly by last, low head 2,16 and garden tubular shell 4 form, body of heater vertically is provided with by its axis (being the axis of garden tubular shell), be vertical being arranged on the leg 11, in be provided with the combustion chamber 3 of gas spray head and igniter (with combustion gas, coal gas, biogas etc. are fuel) be arranged on body of heater inner chamber top position, the fuel gas inlet pipe 13 that is arranged on housing 4 tops is connected with combustion chamber 3, the pipeline that is used for heat exchange is connected with combustion chamber 3, circulate for combustion gas as heat pipe (heat medium flow is threaded a pipe), this heat pipe spirals downwards by spiral way, until being connected with the gas outlet pipe 9 that is arranged on housing 4 bottoms; Water inlet 10 is arranged on housing 4 bottoms, and delivery port 1 is arranged on upper cover 2 center of top.Like this, thermal medium (combustion gas) in heat pipe from top to bottom, (take from fuel gas inlet pipe 13 in combustion chamber 3 and heat pipe air blast as power), cold medium (water) is outside heat pipe, between pipe and be full of inboard wall of furnace body, from bottom to top form reverse flow (by the pressure head of running water), finish heat exchanging process.Fig. 3 illustrates a kind of form of heat pipe, and it is connected to end by the multi-turn heat pipe of in the vertical direction spaced set and constitutes, and the outlet of promptly going up a circle heat pipe is again simultaneously inlet tube of next circle heat pipe; And every circle heat pipe adopts stainless steel tube to be welded as regular hexagon, by the horizontal direction setting, outlet 14 as a last circle heat pipe 6 among Fig. 3 is again simultaneously the inlet tube of next circle heat pipe 7, if a last circle heat pipe 6 is as the first lap heat pipe, its inlet tube 5 directly is connected with combustion chamber 3, and the inlet tube 8 of next circle heat pipe 7 is simultaneously as next encloses the inlet tube of heat pipe again.(perhaps referring to Fig. 3, the outlet of a last circle heat pipe 6 is communicated with the import of next circle heat pipe 7 through bending directly), Fig. 4,5 illustrated the another kind of form of heat pipe, and it is the coiled pipe 15 that adopts stainless steel tube to make.The inlet tube 5a of coiled pipe 15 directly is connected with combustion chamber 3.The other end of coiled pipe 15 is connected with gas outlet pipe 9.Sewage draining exit 12 (see figure 2)s are arranged on low head 6 bottom center positions, are used for the dirt of discharging precipitation regularly.
