Description

The dehydration adapted device of coking residual sludge

Technical field

The utility model relates to Technologies of Coke Plant Wastewater Treatment field, the dehydration adapted of especially a kind of coking residual sludge is filled It sets.

Background technique

The excess sludge of disposal of coking plant waste water system includes that biochemical sludge and mixed heavy sludge, domestic coking industry are useless to it The excess sludge that water treatment system generates, mostly uses greatly sludge dewatering equipment matched with waste water treatment system, excess sludge is taken off It is packed into bucket after water, dewatered sludge is transported to coal yard with vehicle, then dewatered sludge is blended into simultaneously by coking coal by load wagon It is sent into coke furnace carbonization chamber coking, or is sent into the processing side of coke furnace carbonization chamber coking after being simply directly incorporated on mixed coal belt Formula.

1, long flow path, low efficiency are had the disadvantage that using above system processing sludge: dewatered sludge caches through bucket, Vehicle transhipment and the blending of coal yard vehicle, coal yard caching, process flow is long, need to could be most sent within 48 hours coke oven fastly, locates Manage low efficiency, be unable to meet production in a large amount of excess sludges processing burden requirements.2, pollution is big: since sludge distributes certain evil It is smelly, blended the coal charge of sludge to the post of stop or approach cause biggish pollution.3, it is big to consume artificial amount: each work Day day shift need to occupy an operative employee and carry out sludge dewatering operation, and occupy a transit vehicle driver change bucket dress mud, Transport mud operation；In addition, also taking up a load wagon driver carries out coal yard blending operation.4, rainy day coal yard can not receive sludge: de- Sludge itself also contains a certain amount of moisture after water, when meeting rainy day coal yard ponding, cannot receive dewatered sludge again, cause at sewage Reason system sludge can not be discharged, and influence the normal technological operation of waste water treatment system, and cause outer draining discharge beyond standards.5, coal yard Blend and irregular cause mass loss big: dewatered sludge contains many inorganic matters, be incorporated in coking coal blend it is irregular can pair Coke quality generates apparent influence.Dewatered sludge is sent to coal yard, and loaded vehicle is needed to blend dewatered sludge and coking coal materials It just can enter coal blending process afterwards.It, can not due to very low to dewatered sludge-coal charge mixing proportion control accuracy using vehicle Guarantee the stability for entering the cooperation coal quality of coking by coke oven, the coke quality fluctuation that coke oven is produced is larger.When serious, it will lead to The blast furnace working of a furnace has some setbacks, and material consumption, energy consumption increase, and cost is sharply increased.In view of the presence of above-mentioned limitation, coke-oven plant is handled at present The mode processing mode of excess sludge can not disposably be completed to be dehydrated sludge, and be precisely incorporated in coking mixed coal and handle Requirement.Increasingly stringent with " coking industry pollutant emission standard ", the current excess sludge processing mode in coke-oven plant is It is unable to meet production and environmentally friendly needs, need to improve.
