Abstract
Provided is a gasifier wet ash handling device, comprising a dehydrating unit, which is communicated with a central storage bin, a feeding unit, a wet ash transportation pump and a boiler feeder in order. According to the utility model, by comprehensive utilization of discharged ash which is produced by the gasifier, the on-site pollution problem is solved and good economic benefits are achieved.
Description
Technical field
The utility model relates to a kind of ashes treating apparatus, and the wet ash specifically producing for gasification furnace is because phosphorus content is higher, and the wet ash handling equipment that it is fully utilized.
Background technology
The ature of coal difference of domestic various places is larger, therefore domestic many coal chemical industry enterprises require gasification technology to coal wide accommodation, especially require gasification technology to need to adapt to " three high coals ", but coal qualitative difference can be brought the problem of gasification furnace unburned carbon in flue dust too high (25-40%) simultaneously.Factory is mainly to take out for the processing mode of flying dust at present, has caused very large energy dissipation and environmental pollution.
Utility model content
The utility model provides a kind of device that the wet ash of gasification furnace generation is processed, and reaches the object of energy-saving and emission-reduction.
For this reason, adopt following technical scheme: a kind of wet ash handling equipment, this treating apparatus comprises dewater unit, this dewater unit is communicated with middle warehouse, charging gear, wet grey delivery pump, boiler dispenser successively.
The utility model, by the comprehensive utilization to the wet ash of gasification furnace generation, has solved on-the-spot pollution problem, and can bring good economic benefit.Concrete Economic and Efficiency Analysis is as follows:
The dry base caloric value of gasification furnace ash discharge is about 3000kcal/kg, and buck is down to through dewater unit that moisture caloric value is about 1500kcal/kg below 40%, and the wet ash of 1kg can produce the heat of 1500kcal, is equivalent to 0.214kg standard coal.With 600,000 tons/a ammonia production capacity, calculate, gasification furnace can produce the about 30t/h of wet ash amount, mixes after CFB boiler combustion, (to get Q4=0.2) and can save standard coal approximately 5.13 t/h.Because whole process belongs to continuously, steady production process (with main process unit synchronous production, year operating time coupling), device belongs to closed system substantially, has also solved and has stacked the problem of environmental pollution bringing simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to Fig. 1, a kind of wet ash handling equipment, this treating apparatus comprises dewater unit 101, should
dewater unit 101as: centrifugal drier, plate and frame type filter-press or vacuum filter are communicated with as ZSL200 type as plunger type feed pump, boiler dispenser 105 with middle warehouse 102, charging gear 103 as spiral batcher, wet grey delivery pump 104 successively.Its course of work is: the buck that gasification furnace produces is delivered to dewater unit 101 dehydrations through pipeline and obtains wet ash (water content is approximately below 40%), water send process unit reuse after collecting, wet ash falls into warehouse 102 from dewater unit 101 outlets, then by pipeline, through boiler dispenser 105, delivers to boiler combustion after charging gear 103 is sent into wet grey delivery pump 104 pressurizations.
