Abstract
The utility model discloses an energy saving and emission reduction coal-fired boiler which comprises a boiler body, a dust remover, a draught fan and a chimney. The dust remover is respectively connected with the boiler body and the chimney through a chimney flue. A heat recovery device is arranged on the chimney flue which is used for connecting the dust remover and the boiler body. A water sprayer is arranged on the inner wall of the chimney. The energy saving and emission reduction coal-fired boiler is novel in structure and remarkable in effect. Due to arrangement of the heat recovery device, waste heat in the chimney can be reused, energy is saved, and emission of pollution is reduced. Due to the fact that water is used for secondary dust removing of coal smoke, smoke and sulphur content of final emission are lowered, pollution to environment is reduced and noise is lowered.
Description
Technical field
The utility model relates to a kind of coal-burning boiler, especially a kind of energy-saving emission-reducing coal fired boiler that reduces soot emissions and improve heat energy utilization.
Background technology
The fast development of the modernization of industry has brought energy shortage and environmental protection problem, also is the key problem of the world today, and with sustainable development mode protection of the environment with to use non-renewable resources are important topics that current scientific worker need to study.Boiler is as a kind of energy, power-equipment, for obtain to produce, the needed steam of life technique, hot water, just need to consume a large amount of energy resources, and the flue gas serious environment pollution that discharges of boiler.So energy savings, to reduce pollution emissions be the problem that field of boilers need to solve.
The used boiler of existing China mostly is coal-burning boiler, traditional coal-burning boiler is that boiler body directly is connected by flue with the cylindrical shape deduster, enter the heavier pollutant that contains in the coal smoke of deduster and sink to gathering-device in the deduster at Action of Gravity Field, the other end of deduster directly with discharge coal smoke chimney be connected by flue, air-introduced machine is located in the deduster, the dust remover for coal boiler of this structure can not effectively be removed the pollutant in the coal smoke, waste heat in the chimney can not take full advantage of, and can produce larger noise, environment and resident's health there is larger infringement.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of energy-saving emission-reducing coal fired boiler.
To achieve these goals, the technical solution adopted in the utility model is: a kind of energy-saving emission-reducing coal fired boiler, comprise boiler body, deduster, air-introduced machine and chimney, described deduster is connected with chimney with boiler body respectively by flue, described flue for connecting deduster and boiler body is provided with heat-energy recovering apparatus, and described inner wall of stack is provided with sprinkler head.
As preferably, described sprinkler head is located at the inner wall of stack of chimney and below, flue junction.
As preferably, described air-introduced machine is located in the chimney.
As preferably, be provided with particulate filter in the described heat-energy recovering apparatus.
Compared with prior art, the utility model has the advantage of: novel structure, effect is obvious, and the setting of heat-energy recovering apparatus can recycle waste heat in the chimney, has saved the energy and has reduced the discharging of polluting; Adopt water that coal smoke is carried out final dusting, reduced flue dust and the sulfur content of final emission, reduced the pollution to environment, and reduced noise.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1, boiler body; 2, deduster; 3, air-introduced machine; 4, chimney; 5, flue; 6, heat-energy recovering apparatus; 7, sprinkler head; 8, particulate filter.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As a kind of embodiment of the present utility model, consult Fig. 1, comprise boiler body 1, deduster 2, air-introduced machine 3 and chimney 4, it is characterized in that: described deduster 2 is connected with chimney with boiler body 1 respectively by flue 5 and is connected, described flue 5 for connecting deduster 2 and boiler body 1 is provided with heat-energy recovering apparatus 6, described chimney 4 inwalls are provided with sprinkler head 7, described sprinkler head 7 is located at chimney 4 inwalls of chimney 4 and below, flue 5 junctions, chimney 4 belows are provided with at least three ponds, the clear water that extracts in one of them pond with water pump sprays, the another one pond receives the sewage in the chimney 4, at this moment, in all the other ponds sewage is precipitated, each pond receives sewage in turn, the process of precipitation and the spray that supplies water.
Be provided with particulate filter 8 in the described heat-energy recovering apparatus 6, the coal smoke that is discharged in deduster 2 and the chimney 4 is further reduced, reduced the discharging of polluting.Described air-introduced machine 3 is located in the chimney 4, and the position of air-introduced machine 3 is on the inwall of chimney 4, and is parallel with the position of flue 5 junctions with chimney 4, like this can noise reduction.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from the spirit or scope of the present utility model in other embodiments realization.Therefore, the utility model will can not be limited to these embodiment shown in this article, but will accord with principle disclosed herein and features of novelty the widest consistent scope.
