Description

A kind of waste heat boiler
Technical field
The utility model relates to technical field of solar, particularly relates to a kind of waste heat boiler.
Background technology
Boiler is a kind of energy conversion, and the energy to boiler input has chemical energy, electric energy in fuel, and boiler exports steam, high-temperature water or the organic heat carrier with certain heat energy.The original meaning of pot refers to the water container heated on fire, and stove refers to the place of combustion fuel, and boiler comprises pot and stove two large divisions.The hot water produced in boiler or steam directly for industrial production and people's lives provide required heat energy, also can be converted to mechanical energy by Steam Power Equipment, or by generator, mechanical energy are converted to electric energy again.There is provided the boiler of hot water to be called hot-water boiler, be mainly used in life, in industrial production, also have a small amount of application.The boiler producing steam is called steam boiler, often referred to as boiler, is used for thermal power station, boats and ships, locomotive and industrial and mining enterprises.
The high-temperature flue gas that existing boiler is produced when burning generally discharges after dust treatment, although so effectively protect environment, the heat in flue gas is wasted, and cause the loss of energy, energy-saving effect is poor.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of waste heat boiler.
The utility model is achieved through the following technical solutions:
A kind of waste heat boiler, comprise boiler body, described boiler body upper inside is provided with heating chamber, and downside is provided with combustion chamber, and described combustion chamber side is provided with blast pipe, the inside of described combustion chamber is provided with combustion tube, described combustion tube is provided with several steam vents, and described combustion tube one end is connected with combustion fan, described blast pipe one section U-shaped structure in return water tank, U-shaped structure is provided with some pieces of heat-conducting plates from top to bottom successively, and the madial wall of described return water tank is provided with thermal insulation layer.
As optimal technical scheme of the present utility model, described vent shape is circular or oval.
As optimal technical scheme of the present utility model, described heat-conducting plate is that aluminium sheet is made.
As optimal technical scheme of the present utility model, described thermal insulation layer is pasted onto on the madial wall of return water tank, and thickness is 2mm ~ 5mm.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model is by arranging combustion tube and combustion fan, under the effect of combustion fan, produce gas like this enters in combustion chamber through combustion tube, makes the more abundant of fuel combustion; By arranging return water tank, such high-temperature flue gas is in return water tank, and heat-conducting plate can transfer heat to the water in water tank, and the heat of flue gas is re-used, improves the utilization rate of heat, decrease the waste of heat, practicality is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. boiler body; 101. heating chamber; 102. combustion chamber; 2. combustion fan; 3. combustion tube; 301. steam vent; 4. blast pipe; 5. return water tank; 6. heat-conducting plate; 7. thermal insulation layer.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of waste heat boiler, comprise boiler body 1, described boiler body 1 upper inside is provided with heating chamber 101, downside is provided with combustion chamber 102, and described combustion chamber 102 side is provided with blast pipe 4, and the inside of described combustion chamber 102 is provided with combustion tube 3, described combustion tube 3 is provided with several steam vents 301, wherein said steam vent 301 shape is circular or oval, produces gas like this and enters in combustion chamber 102 through combustion tube 3, make the more abundant of fuel combustion under the effect of combustion fan 2.Described combustion tube 3 one end is connected with combustion fan 2, and described blast pipe 4 one sections U-shaped structure in return water tank 5, U-shaped structure is provided with some pieces of heat-conducting plates 6 from top to bottom successively, and wherein said heat-conducting plate 6 is made for aluminium sheet.The madial wall of described return water tank 5 is provided with thermal insulation layer 7, and wherein said thermal insulation layer 7 is pasted onto on the madial wall of return water tank 5, and thickness is 2mm ~ 5mm, and such thermal insulation layer 7 can reduce the loss of heat.
Its detailed description of the invention is: high-temperature flue gas is in return water tank 5 like this, and heat-conducting plate 6 can transfer heat to the water in water tank, and the heat of flue gas is re-used, improves the utilization rate of heat, decrease the waste of heat, practicality is good.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
