Description
Technical Field
The utility model belongs to the technical field of a boiler that is used for steam to cook food, domestic heating, hotel's bathing, concretely relates to biomass boiler of smokeless environmental protection.
Background
At present, common biomass boilers on the market have the advantages of low heat efficiency, slow steam generation, large occupied area, complex installation, no energy conservation and no environmental protection. For example, patent CN206831820U discloses a smokeless and environment-friendly biomass boiler, which has a complex structure, and the heat in the furnace heats the water in the coil, so that the heat efficiency and the utilization rate are low.
Disclosure of Invention
In order to solve the problems in the prior art, the utility model discloses a smokeless environment-friendly biomass boiler, which is provided with a hearth, a furnace and a water body from inside to outside; the boiler is provided with a rotary flue in the outer furnace pipe of the hearth, the rotary flue comprises a first flue and a second flue, the first flue is connected with the hearth and the second flue, and the second flue is connected with a flue gas outlet.
A ring wall is arranged between the hearth and the furnace pipe; the hearth wall and the ring wall enclose a first flue, and the ring wall and the furnace shell enclose a second flue; a first gap is reserved between the top of the hearth and the top cover of the furnace pipe, and the first gap is used as an inlet of a first flue; the top end of the annular wall is hermetically connected with the furnace pipe top cover, and a second gap is reserved between the bottom end of the annular wall and the furnace pipe shell; the second gap serves as an inlet for the second flue.
The hearth is communicated with a first flue through a first gap, the first flue is connected with a second flue through a second gap, and an outlet of the second flue is connected with a flue gas outlet; heat generated by combustion of fuel in the hearth flows from top to bottom in the hearth through the first flue and then flows from bottom to top through the second flue.
A fire grate is arranged at the bottom of the hearth, and an air blowing layer is arranged below the fire grate; the blast layer is connected with the blast port.
The boiler furnace and the boiler shell are enclosed to form a water body, an upper charging opening is formed in the top cover of the boiler furnace and extends out of the boiler shell, and the upper charging opening is communicated with the hearth. Biomass fuel or fuel such as coal may be added to the upper charging port.
The technical scheme of the utility model, firstly adopt the technical scheme of ring body water cladding furnace pipe, furnace, make between the heat in the furnace add the internal water of hot water, secondly adopt the circle shape flue, the heat in the make full use of flue continues to add the internal water of hot water, and the circle shape flue can prolong the formation of flue gas, makes the dust deposit in the flue, and the flue gas continues to clear up in long stroke, and is almost smokeless in the exhanst gas outlet.
The common boiler can be smokeless only by adding a set of dust removal equipment, and the product can achieve the effects of smokeless, energy-saving, environmental protection and rapid steam generation without adding the dust removal equipment, thereby reducing the cost and lightening the investment pressure of consumers.
