Description
Technical field
The utility model relates to a kind of boiler, particularly relates to a kind of efficient energy saving and environment friendly boiler.
Background technology
At present, generally the heat-exchanger rig of the boiler of Shi Yonging is to adopt tubular type or furnace wall heat exchange, adopt many pipes as water channel, water heating through piping and body of heater, send into the heat supply district, the combustion chamber of these boilers mostly is enclosed construction greatly, the bottom is a planar structure, because the fuel in the combustion chamber can not fully contact with air, causes fuel fully to burn, the thermal efficiency is low, and easily produce black smoke, contaminated environment, and the easy scaling of ducted water, cause heat exchanger effectiveness to reduce, reduce service life.
Summary of the invention
For addressing the above problem, the utility model provides a kind of efficient energy saving and environment friendly boiler, can make full combustion of fuel, improves the thermal efficiency.The technical scheme that addresses the above problem is as follows:
A kind of efficient energy saving and environment friendly boiler comprises housing, combustion chamber and heat transfer zone, and the top of described sidewall of combustion chamber is provided with air outlet, and bottom of furnace body is provided with ajutage between the air outlet on top; Described heat transfer zone is the space in addition, combustion chamber within the housing, this heat transfer zone comprises the flue between water channel and the heat exchange screen, described water channel is the space between outer wall of combustion chamber, heat exchange screen and the housing, and described heat exchange screen is perpendicular to the housing bottom surface and is mutually circuitous parallel screen shape structure.
At least one arm is set on the described ajutage.
Described arm is distributed in the middle part or the bottom of described ajutage.
Between the described heat exchange screen water pipe that at least one links to each other with water channel is set.
Bottom, described combustion chamber is the structure to the combustion chamber convex.
The bottom of described combustion chamber is the trapezium structure to the combustion chamber convex.
Described combustion chamber is a composite chamber, and the internal diameter of combustion chamber reduces from bottom to top step by step.
The top of sidewall of combustion chamber of the present utility model is provided with air outlet, bottom of furnace body is provided with ajutage between the air outlet on top, therefore fuel can fully contact with air, make full combustion of fuel, both made owing to part of fuel does not have coal smoke gas that fully burning produces also can be in the second-time burning of air outlet place, really reach no black smoke and produce the beneficial effect of few flue dust.
Water channel of the present utility model is the space between outer wall of combustion chamber, heat exchange screen and the housing, therefore, the outer wall of combustion chamber can with water direct heat-exchange, this structure makes the temperature of furnace wall be unlikely to too high, and needn't adopt the very high refractory material of refractoriness, reduce cost, also improved the thermal efficiency simultaneously.
In a preferred implementation of the present utility model, the bottom of combustion chamber is the structure to convex, this structure has improved bearing capacity, and the bottom surface area of this structure is bigger than the bottom surface area of plane combustion chamber, increased the contact area of fuel and air, the fuel of bottom, combustion chamber can be burnt more fully.
Flue of the present utility model is the space between heat exchange screen and the heat exchange screen, because the heat exchange screen is perpendicular to the housing bottom surface and is mutually circuitous parallel screen shape structure, this just make the same flue of flue, water channel with water channel and flue with being parallel to each other between the water channel, this circuitous parallel construction of heat exchange screen helps the heat-exchange time of prolong smoke at flue, increased the heat exchange area of flue gas and water, effectively reduce exhaust gas temperature, significantly reduced incrusted speed, improved the thermal efficiency.In a preferred embodiment, also be provided with the water pipe that links to each other with water channel between the described heat exchange screen, the setting of this water pipe can increase heat exchange area, improves the thermal efficiency, has also played the effect of reinforcing simultaneously.
The efficient energy saving and environment friendly boiler that the utility model provides can make full combustion of fuel, improves the thermal efficiency, the environment protecting that really reaches no black smoke and produce few flue dust.

The specific embodiment
As depicted in figs. 1 and 2, efficient energy saving and environment friendly boiler of the present utility model is made of housing 13, the combustion chamber 2 and the heat transfer zone that are positioned at housing one side.Fuel adds combustion chamber 2 through bunkering port 22, after in combustion chamber 2, carrying out the burning first time, what produce not have the flue gas that burns when the top, combustion chamber because of anoxic, carry out second-time burning with air that enters 2 tops, combustion chamber by the blast pipe 3 that is provided with some arms and the air by air outlet 15 at this, because sufficient air is arranged to be supplied with, make second-time burning more abundant, gas fume after burning enters flue 4.Pot body 19 by many groups perpendicular to the bottom surface of housing 13 and circuitous mutually parallel heat exchange screen 5 and connect water pipe 6 and constitute, between the heat exchange screen 5 is flue, water to be heated enters boiler by water inlet pipe 14, after water channels that process outer wall of combustion chamber, housing 13 and heat exchange screen 5 constitute and flue gas carry out abundant heat exchange, enter the heat supply district by outlet pipe 11.Be provided with the water pipe 6 that links to each other with water channel between the heat exchange screen 5, can increase heat exchange area, improve the thermal efficiency, also played the effect of reinforcing simultaneously.The terminal outlet flue 7 of flue is furnished with air-introduced machine 20.
As shown in figures 1 and 3,9 is upper flue, 10 are fixing muscle, 12 is emergency vent, owing to the dust that precipitates in the smoke evacuation process, 16 was observation panel in clear cigarette ash mouth 8 was used for cleaning flues, and cleaning door 18 is used to clear up the ashes in the combustion chamber, breast hole 17 is used to clear up the slag in the combustion chamber, and 21 is sewage discharge outlet.
As shown in Figure 1,1 is trapezium structure at the bottom of the combustion chamber of efficient energy saving and environment friendly boiler of the present utility model, and this trapezium structure not only can strengthen supporting fuel, as the bearing capacity of coal, and increased the contact area of fuel and air, make fuel especially bottom fuel can burn more fully.
