Abstract

The utility model provides an automatic coal-falling smokeless boiler, which belongs to the manufacturing field of the boiler, and resolves the problem that the ordinary boiler discharges the black smoke, and comprises a combustion chamber that is shaped like the Chinese character ER, a small drum, a big drum, a heat-exchanging quirk vertical pipe, a boiler housing, a flue, an oxygen inlet hole, a coal hopper, firebars and an electric vibration machine, wherein, the coal hopper is arranged at one side on the bottom of the combustion chamber to be communicated with the hearth, and the firebars of the hearth are installed at an angle of 30 degrees to 50 degrees, thus changing the traditional paralleling firebars, and favoring the automatic intake of the coal that is arranged inside the coal hopper into the hearth to be burned adequately under the vibration of the electric vibration machine; the length of the combustion chamber that is shaped like the Chinese character ER is 1 to 1.8 m, thus lengthening the combustion space and increasing the combustion time, so that the produced smoke and the coal particles are suspended to be burned, and no black smoke produces, and the coal is completely transformed to the heat, thereby improving the utilization rate of the heat energy; and the smoke dust emission is better than the national standard, and the utility model is an ideal automatic coal-falling smokeless boiler.

Description

The coal less boiler falls automatically

One, technical field

The utility model relates to a kind of boiler processing technique field, specifically relates to a kind of coal less boiler that falls automatically.

Two, background technology

Continuous development along with society; people's the protection consciousness to environment is more and more stronger; thereby energy saving and environment friendly boiler also more and more is subjected to people's attention and welcome; China is the production of coal and uses big country; industrial coal and coal consumption of living use amount are very big; continually developing and utilizing along with coal; the coal resources of China are fewer and feweri; therefore the thermal efficiency that improves and make full use of coal is very to need the problem that solves, and the transformation by boiler structure can make coal burn fully, improves the thermal efficiency of coal; reduce the exhaust emission of flue dust; the environment that purifies air, thus reach the purpose of energy-conserving and environment-protective, and the boiler structure of prior art is varied; most boiler structures is unreasonable; coal burning is insufficient, produces a large amount of flue dust in combustion process, and Dark smoke billows; the soot emissions severe overweight; do not meet the requirement of national energy-saving and emission-reduction, not only wasted resource but also polluted environment, research and develop the energy-efficient coal less boiler that falls automatically and be very important.

Three, summary of the invention

The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of safe and reliable, rational in infrastructure, pure bituminous coal of burning not over-emitting black exhaust, energy-conservation, efficient, quick heating, thermal efficiency height, no flue dust discharging, environmentally safe, the coal less boiler that falls automatically applied widely are provided.

In order to solve the problems of the technologies described above, the utility model is achieved in that and comprises " youngster " font combustion chamber, little drum, big drum, heat exchange quirk standpipe, boiler jacket, flue, feeding oxygen hole, coal bunker, fire bars, the electricity machine that shakes; Bottom one side of described " youngster " font combustion chamber is provided with coal bunker and is communicated with burner hearth, and opposite side is provided with feeding oxygen hole, and the fire bars of burner hearth is that rake angle is installed, and the space that burner hearth one side and boiler jacket form is provided with U type water jacket; Form around the water high-temperature region between " youngster " font combustion chamber and the little drum, its top is connected with outlet pipe; Form between little drum and the big drum that " is circuitous to be connected with the heat exchange quirk standpipe bottom that is located at the annular space that forms between big drum and the boiler jacket around space, quirk loop, heat exchange quirk riser upper is communicated with fume collecting chamber, flue.Described " youngster " font combustion chamber is long to be 1---1.8 rice.Described flue is arranged on the side on boiler jacket top.Described heat exchange quirk standpipe is many and evenly is provided with on a circle and the big drum.Be provided with the electricity machine that shakes in the described coal bunker.Described fire bars setting angle is the 30-50 degree.

Owing to adopt technique scheme, the utlity model has automatic ventilation oxygenation, make flue gas and little carbon granules of generation change into heat fully at " youngster " font combustion chamber suspension combustion, extended combustion space and burning time, improve the utilization rate of heat energy, further realized the optimum state of heat exchange, thereby reached the smokeless and dust free discharge standard.

Four, description of drawings

Accompanying drawing is a structural representation of the present utility model

Among the figure 1, boiler jacket 2, big drum 3, pannikin tube 4, " youngster " font combustion chamber 5, heat exchange quirk standpipe 6, flue 7, feeding oxygen hole 8, coal bunker 9, fume collecting chamber 10, electricity shake machine 11, fire bars 12, outlet pipe 13, water jacket

Five, specific embodiments

In conjunction with the accompanying drawings the utility model is further described.

Less boiler of the present utility model, its structure are that " youngster " font combustion chamber 1, pannikin tube 3, big drum 2, heat exchange quirk standpipe 5, boiler jacket 1, flue 6, feeding oxygen hole 7, coal bunker 8, fire bars 11, the electricity machine 10 that shakes constitutes; Successively " youngster " font combustion chamber 4 and pannikin tube 3, big drum 2, boiler jacket 1 welding are fixed from inside to outside; On big drum 2, weld, evenly be provided with a circle heat exchange quirk standpipe 5 between boiler jacket 1 and the big drum 2 and be many, to reach abundant absorption heat, reduce exhaust gas temperature, the upper end is connected with fume collecting chamber 9, flue 6, the lower end makes a circulation to be connected around space, quirk loop with the " that big drum 2 and pannikin tube 3 form, strengthened heating surface area and burning time, improved the utilization rate of heat energy, further realized the optimum state of heat exchange; Space between " youngster " font combustion chamber 4 and the pannikin tube 3 is around the water high-temperature region, and top and outlet pipe 13 are welded to connect; Described flue 6 is arranged on the side on boiler jacket 1 top.Described feeding oxygen hole 7 is located at a side of boiler jacket 1 bottom, and the fire bars 11 of burner hearth has changed traditional open hearth bar for installing for 30-50 degree rake angle; Be provided with the electricity machine 10 that shakes in the described coal bunker 8, the coal that helps coal bunker 8 enters burner hearth fully burning on fire bars 11 automatically under electricity shakes the vibration of machine 10; The space that burner hearth one side and boiler jacket 1 form is provided with U type water jacket 13 so that abundant preheating is heated to the water in the boiler, guarantees effective utilization of heat; " youngster " font combustion chamber is long to be 1---1.8 rice, the combustion space and prolonged burning time of having extended, the flue gas that make to produce and little carbon granules suspension combustion, change into heat fully, do not produce black smoke, improved the utilization rate of heat energy, realized that the smokeless and dust free discharging has reached national requirements for environmental protection.
