SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an energy-conserving formula boiler improves thermal utilization ratio, reduces the waste of heat.

In order to achieve the above object, the basic scheme of the utility model is: an energy-saving boiler comprises a boiler body, wherein a smoke exhaust pipe is arranged at the bottom of the boiler body, an air outlet pipe is further arranged on the boiler body, a first smoke collecting cavity is formed in the boiler body, an ignition device is arranged in the first smoke collecting cavity, the smoke exhaust pipe is in a snake shape, the head end of the smoke exhaust pipe is communicated with the first smoke collecting cavity, and the tail end of the smoke exhaust pipe is communicated with the air outlet pipe; the corner of the smoke exhaust pipe is provided with a convex block, and the convex block is positioned inside the smoke exhaust pipe.

The working principle and the beneficial effects of the basic scheme are as follows:

in the process of researching heat exchange of a boiler, the inventor finds that when smoke flows in a smoke exhaust pipe, the smoke exhaust pipe is longer due to a larger furnace body, and the temperature change in the smoke exhaust pipe is different due to the fact that the smoke exhaust pipe is longer due to the fact that the smoke exhaust pipe is only arranged with a simple structure in the prior art; in addition, the flue gas in the smoke exhaust pipe is in the same position of the smoke exhaust pipe, the temperature of the flue gas is also different, one side of the smoke exhaust pipe discharging heat, namely the heat transferred by one side close to the pipe wall of the smoke exhaust pipe, is lower than the temperature of the flue gas in the middle of the smoke exhaust pipe, the smoke exhaust pipe with a simple structure is generally adopted in the prior art, for example, a longer straight pipe is adopted, the flue gas with higher temperature in the middle of the smoke exhaust pipe is directly discharged under the condition that the flue gas is not fully utilized, the heat is not effectively utilized, and the heat energy waste is caused.

The pipe of discharging fume sets the snake shape to among this technical scheme, can make the flue gas that gets into in the pipe of discharging fume change flow direction in the corner of the pipe of discharging fume, can also make the flue gas produce the effect of collision in the corner when changing flue gas flow direction simultaneously, thereby make the flue gas that is close to the pipe wall of discharging fume and discharge fume the flue gas in the middle of the pipe and produce the effect of mixing, flue gas in the pipe of discharging fume is always collided then remixed like this, make the temperature of flue gas keep relative even, simultaneously also abundant utilization lie in the heat of the higher flue gas of pipe intermediate position temperature of discharging fume, reduce thermal loss rate.

Still set up the lug in the corner of discharging fume the pipe among this technical scheme, the setting of lug can produce stronger impact force to the flue gas, strengthens the mixed effect of flue gas, and heat utilization rate is higher.

The snakelike pipe of discharging fume that is that sets up among this technical scheme has increased the length of discharging fume the pipe in the furnace body to make the heat transfer time of flue gas long, and still increased the area of discharging fume the pipe in the furnace body, make the pipe of discharging fume and the increase of the water contact area in the furnace body, the flue gas heat can obtain more abundant utilization.

Further, a cavity is arranged inside the lug, a plurality of orifices are formed in the surface of the lug and communicated with the cavity.

Be equipped with the cavity in the inside of lug and be equipped with the drill way on its surface, can make the flue gas when the corner of discharging fume the pipe produces the collision, do not reduce the volume that the flue gas flows, make the flue gas still can normally pass through, compare in directly setting up inside being solid lug in the corner, reduced the width of discharging fume intraductal circulation, the speed that the flue gas among this technical scheme flows can not receive too big influence.

Furthermore, each corner of the smoke exhaust pipe is respectively provided with two convex blocks, and the two convex blocks are respectively positioned on the upper wall and the lower wall of the smoke exhaust pipe.

The setting of two lugs can produce stronger impact to the flue gas, and the flue gas mixing effect is better.

Further, still include second collection smoke chamber in the furnace body, first collection smoke chamber and second collection smoke chamber are located the furnace body both sides respectively, the outlet duct communicates with one side of second collection smoke chamber, discharge fume the pipe tail end and second collection smoke chamber opposite side intercommunication.

The second collection smoke chamber that sets up among this technical scheme can play the effect that prevents thermal diffusion equally, has further improved thermal utilization ratio.

Further, ignition device includes fire row, ignition needle and flame-out protection needle are located the fire row.

The ignition device in the scheme is simple and is safer in use.

Further, a smoke exhaust fan is arranged in the second smoke collecting cavity.

The smoke exhaust fan can absorb smoke in the first smoke collecting cavity through the smoke exhaust pipe, and meanwhile, the oxygen content of fuel in the combustion process can be increased, and the fuel can be combusted more fully.

Further, the ignition device is provided with at least two.

The ignition device can realize rapid heating and rapidly improve the temperature in the furnace body.

Furthermore, the smoke exhaust pipe is provided with a plurality of smoke exhaust pipes which are distributed around the first smoke collecting cavity.

The many pipes of discharging fume that set up can make the area of contact of discharging fume pipe and furnace body bigger and the heat transfer time increases, has further improved thermal utilization ratio, and will discharge fume around the first collection flue chamber of the distribution of pipe, make high temperature flue gas follow first collection flue chamber all around more even sucked the pipe of discharging fume, flame can not skew to one side like this to the burning is also more even, and is more abundant, has improved the utilization ratio of the energy.

Furthermore, the smoke exhaust pipe is provided with three smoke exhaust pipes, and the head ends of the three smoke exhaust pipes are respectively positioned on three surfaces of the first smoke collecting cavity and are communicated with the first smoke collecting cavity.

The pipe of will discharging fume is equipped with three, compares in a pipe of discharging fume, can shorten the width of discharging fume the pipe in this scheme, not only conveniently makes and installs, can also accelerate the flow of flue gas to can make the flue gas obtain abundant timely mixture.

Furthermore, the corner of the smoke exhaust pipe is in a 90-degree right-angle shape.

The corner setting that will discharge fume the pipe is the right angle of 90 degrees and compares in the corner for glossy curved surface, and this technical scheme's corner is stronger to the impact of flue gas, and is better to the mixed effect of flue gas.
