A burning chamber and a smoke pipeline in the stove body are communicated with by a smoke chamber to form a vertical angle with 90 DEG to cause heat energy to form multiple circulation trend in the stove. A lateral partition board which is provided with a gap and can control water to flow in an S-shaped return stroke is arranged in the body cavity of the stove, and the circumference of the burning chamber and one side of the smoke chamber adjacent to the inner wall of the stove body are provided with current guiding rings. The multiple return-stroke ordinary pressure diesel hot-water stove has the features of large heat-exchange area, high heat efficiency and low oil consumption, and the heat efficiency reaches 92.5%.

Description

Multiple return-stroke ordinary pressure diesel hot-water stove

The utility model relates to a kind of fluid heater that heat-generating device is arranged, and specifically is a kind of many backhauls of combustion diesel oil normal pressure water heater.

Disclosed normal pressure diesel oil water heater has vertical and horizontal two kinds.The combustion chamber of vertical heater is to be contained in the bottom of body of heater and to be connected logical with pipeline group perpendicular to body of heater, making heat energy directly enter pipeline from the combustion chamber promptly discharges from chimney after heat exchange, this stove heat energy flow velocity is fast, heat exchanger time is short, the thermal efficiency is low, stack temperature is more than 250 ℃, and the thermal efficiency is generally below 85%; Though some horizontal chamber furnace (oven) has increased the length of heat energy backhaul, the thermal efficiency increases, but still the problem that does not have fine solution heat energy to make full use of, be in particular in that above-mentioned two kinds of water heater current all are directly to be risen by the bottom, do not solve heat exchange blind area and heating problem of non-uniform, be to isolate simultaneously between outer wall of combustion chamber and the stove inwall, be unfavorable for the utilization of heat energy with refractory brick.

The purpose of this utility model is to provide a kind of improvement stove inner combustion chamber and pipeline configuration thereof, increases the device of the flow direction of restriction water, and heat energy can be made full use of, and improves the water heater of the thermal efficiency.

The concrete scheme that the utility model purpose realizes is: increase in termination, body of heater inner combustion chamber and be connected to smoke-box, the smoke pipe road is connected on the smoke-box rather than directly communicates with the combustion chamber.Reaching smoke-box around the combustion chamber leans on inboard wall of furnace body one to the current guide ring is arranged, to increase heat exchange area.All be to be 90 ° of right angles to be connected logically between stove inner combustion chamber and smoke-box and smoke-box and the pipeline, make heat energy in body of heater, form repeatedly circulation trend, increase heat energy heat exchanger time in stove.In body of heater, be equipped with leaving certain gaps uncovered by the economic plan, can control water and be the bottom-up mobile diaphragm plate of serpentine backhaul, water is heated evenly in stove.

The utility model water heater when being vertical, be with the combustion chamber perpendicular to a side in the body of heater, bottom of furnace body is equipped with the smoke-box of connecting with the combustion chamber, and is connected by smoke-box and smoke pipe road perpendicular to body of heater.When water heater when being horizontal, the combustion chamber is to be contained in bottom of furnace body, and the smoke-box that symmetry row puts more than three is arranged, and connects logical between the smoke-box by the smoke pipe road.

Fuel oil hot water boiler behind the employing such scheme, heat energy and current form repeatedly circulation and walk about in body of heater, increased heat energy heat exchanger time in stove, strengthened heat exchange area, solve heat exchange blind area and hot problem of non-uniform, increased substantially the thermal efficiency, reduced oil consumption.Detect through the Guangxi product quality supervision and testing institute, the thermal efficiency reaches 92.5%.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the longitudinal section of the vertical embodiment of the utility model.

Fig. 2 is Fig. 1 embodiment A-A section plan view.

Fig. 3 is the longitudinal section of the horizontal embodiment of the utility model.

Among the figure 1, water inlet pipe 2, combustion chamber 3, smoke-box 4, current guide ring 5, pod apertures 6, smoke pipe road 7, body of heater 8, dividing plate 9, outlet pipe 10, chimney.

Among Fig. 1-2, throat less chamber 2 vertically stands on a side in the body of heater 7, is connected with 3 one-tenth 90 ° of right angles of smoke-box.To current guide ring 4 is arranged, fixedly smoke-box 3 has pod apertures 5 in the side plate of body of heater 7 walls, so that the current guide ring 4 of combustion chamber 2 and smoke-box 3 communicates by body of heater 7 inwalls one for combustion chamber 2 circumference and smoke-box 3.Smoke pipe road 6 is connected logical with smoke-box 3 perpendicular to body of heater 7.In body of heater 7 chambeies, divide two layers of intersection be symmetrically fixed with two leaving certain gaps uncovered by the economic plans, can control that water is bottom-up does the metal diaphragm plate 8 that serpentine flows.Water inlet pipe 1 is contained in body of heater 7 tops of combustion chamber 2 one sides, and outlet pipe 9 is contained in body of heater 7 opposite sides that are symmetrical in water inlet pipe 1.During use, the heat energy that combustion chamber 2 produces enters smoke-box 3 from top to bottom, upwards enters smoke pipe road 6 again, does two backhauls and walks about the back from chimney 10 discharges.Meanwhile, cold water is from water inlet pipe 1 ingoing stream guide ring 4,2 weeks in week from top to bottom flowed in the combustion chamber, utilize maximum temperature difference cooling combustion chamber and intensification, and then through the guide ring breach and smoke-box water jacket layer pod apertures 5 enters in body of heater 7 chambeies and bottom-uply under the restriction of dividing plate 8 do serpentine three backhauls and flow, make it fully with smoke pipe 6 heat exchanges after from outlet pipe 9 discharges.

In embodiment illustrated in fig. 3, body of heater 7 is horizontal, and combustion chamber 2 levels are contained in body of heater 7 bottoms.Diaphragm plate in the right-hand leaving certain gaps uncovered by the economic plan of body of heater is housed in the body of heater 7, makes the body of heater inner chamber be divided into two parts up and down.3 smoke-boxes 3 are housed in the stove, and smoke-box A is contained in body of heater 7 left side Lower Halves and is connected logical with combustion chamber 2; Smoke-box B is vertically fixed on current guide ring 4 tops of combustion chamber, body of heater 7 right side 2; Smoke-box C is vertically fixed on the diaphragm plate 8 in body of heater 7 left sides, and is connected to chimney 10 above it.Combustion chamber 2 circumference and smoke-box 3 lean on body of heater 7 inwalls one to current guide ring 4 is arranged.Smoke pipe road 6 connects the smoke-box 3 of logical body of heater 7 left and right sides.On body of heater right side, 7 bottom and top left side water inlet pipe 1 and outlet pipe 9 are housed respectively.During use, heat energy enters smoke-box A from the combustion chamber, enters smoke-box B through smoke pipe road 6, enters smoke-box C through the smoke pipe road again, carries out repeatedly return cycle.Meanwhile, water is also bottom-up under the restriction of current guide ring 4 and diaphragm plate 8 to be done the many backhauls of serpentine and flows, and gets rid of from outlet pipe 9 at last.
