Description
Technical field
The present invention relates to a kind of environmentally friendly coal-turned-gas boiler system, belong to boiler plant field.
Background technology
Currently, coal-burning boiler is cheap and easy to get because of coal, can not possibly eliminate in practical situations both, but coal-fired undisputable fact big for environment pollution, main cause is that coal produces a large amount of dust and sulfur dioxide in combustion, therefore, realize that the environmental protection of coal is used, must just avoid producing both to endanger.
The content of the invention
The present invention relates to a kind of environmentally friendly coal-turned-gas boiler system, to realize coal-fired environmental protection is used in boiler plant purpose.
To realize above-mentioned purpose, the present invention is adopted the following technical scheme that：
A kind of environmentally friendly coal-turned-gas boiler system, comprising：Blue-gas generator (1), gravitational precipitator (2), spiral dirt device (3), sulphur removal scrubbing tower (4), liquid trap (5), gas burner (6), gas fired-boiler (7)；As shown in Figure 1.
Below in conjunction with accompanying drawing, technical construction of the invention and method are illustrated：Blue-gas generator (1) is connected with gravitational precipitator (2),Gravitational precipitator (2) is connected with spiral dirt device (3),Spiral dirt device (3) is connected with sulphur removal scrubbing tower (4),Sulphur removal scrubbing tower (4) is connected with liquid trap (5),Liquid trap (5) is connected with gas burner (6),Gas burner (6) hits exactly installed in gas fired-boiler (7) burner hearth front end,Its course of work is,Blue-gas generator (1) is by coal through high temperature and thermal reduction generation water-gas,Water-gas removes big dust particle by gravitational precipitator (2),Then small particles dust is removed by spiral dirt device (3) again,Alkali wash sulphur removal is carried out to the sulfur dioxide of water-gas by sulphur removal scrubbing tower (4) again,Then last time removing is carried out to the moisture content in water-gas by liquid trap (5) again,At this moment water-gas sucks gas fired-boiler (7) burner hearth internal-combustion by gas burner (6),Due to water-gas dust-removing sulphur removing function,The flue gas that whole combustion process is produced is dustless,Without sulphur,Meet environment protection emission requirement.
Beneficial effects of the present invention：Environmental protection and energy saving, it is safe and reliable.
Brief description of the drawings：
Accompanying drawing 1 is structural representation of the invention.
Specific embodiment：
In order that technical scheme becomes more apparent, below in conjunction with drawings and Examples, the present invention is described in more detail, instantiation described herein, is only used to explain the present invention, is not intended to limit the invention.
Embodiment：
Refer to shown in accompanying drawing 1,Blue-gas generator (1) is connected with gravitational precipitator (2),Gravitational precipitator (2) is connected with spiral dirt device (3),Spiral dirt device (3) is connected with sulphur removal scrubbing tower (4),Sulphur removal scrubbing tower (4) is connected with liquid trap (5),Liquid trap (5) is connected with gas burner (6),Gas burner (6) hits exactly installed in gas fired-boiler (7) burner hearth front end,Its course of work is,Blue-gas generator (1) is by coal through high temperature and thermal reduction generation water-gas,Water-gas removes big dust particle by gravitational precipitator (2),Then small particles dust is removed by spiral dirt device (3) again,Alkali wash sulphur removal is carried out to the sulfur dioxide of water-gas by sulphur removal scrubbing tower (4) again,Then last time removing is carried out to the moisture content in water-gas by liquid trap (5) again,At this moment water-gas sucks gas fired-boiler (7) burner hearth internal-combustion by gas burner (6),Due to water-gas dust-removing sulphur removing function,The flue gas that whole combustion process is produced is dustless,Without sulphur,Meet environment protection emission requirement.
