Buck multistage absorbing devices include clinker water conveyer, negative pressure generator, and negative pressure generator is by clinker water conveyer
Bottom produce negative pressure cause that the buck in clinker water is spun off by suction strainer, the clinker water in the presence of clinker water conveyer
Constantly advance, as the advance of clinker water and the effect of negative pressure generator cause that clinker water forms multistage suction during advancing
Filter, clinker water gradually solidify to form pie, and the buck that suction strainer goes out is used by pipeline to space flight gasification furnace coal ash spray equipment
In the coal ash that space flight gasification furnace is produced is sprayed into clinker water, recycling for water resource is formed.
（3）The coal ash for being solidified into pie is delivered to feed bin by belt conveyor, and stirring motor, pie are provided with feed bin
Coal ash stirred in feed bin and form wet coal ash, wet grey pump is then delivered to by malleation batcher, it is defeated finally by wet grey pump
Boiler is delivered to be burnt.
The advantage of the invention is that：1. space flight slag from gasifying furnace water joint disposal of the invention devises one with Application way
Cover the complete space flight gasification furnace Treatment of Coal Ash that the wet coal ash stirred from coal ash spray humidifying to final curing enters boiler combustion
With utilize flow, the filter cake humidity that clinker water is formed after multistage suction strainer solidifies is uniform, and it is high to reclaim combustion utilization efficiency, solves
Lime-ash water cure is of poor quality, and the low problem of combustion utilization efficiency, space flight slag from gasifying furnace water has obtained effective recycling, saves
Resource and production cost, reduce environmental pollution；2. it is completely embedded between each processing step, can effectively ensures system stream
The stable operation of journey, contributes to the continuous prodution of chemical enterprise, simplifies operation.3. the buck that suction strainer goes out passes through pipeline
Humidifying is carried out to space flight gasification furnace coal ash to spray equipment, the recycling of water resource has been reached, water resource has been saved, reduced
The environmental pollution that buck discharge is caused, is conducive to environmental protection.
