Description

JJ

Изобретение относитс  к переработке осадков , образующихс  в системах очистки городских и промышленных сточных вод.The invention relates to the processing of sludge produced in municipal and industrial wastewater treatment systems.

Известен способ обезвоживани  осадков сточных вод, заключающийс  в том, что влажный осадок питателем подаетс  на смешение с гор чим газом в трубопровод, после чего образуюпда с  в нем смесь топочных газов и частично подсушенного осадка направл ют в сушилку взвешенного сло , а затем окончательно высушенный осадок собирают в бункере .A known method for dewatering sewage sludge is that a wet sludge is fed by a feeder for mixing with hot gas into a pipeline, after which a mixture of flue gases and partially dried sludge is formed in it and sent to a suspended layer dryer, and then finally dried sludge collected in the bunker.

При этом отмечаетс  частичное выгорание осадка, которое обусловлено комкованием и неравномерной подачей осадка, а также мала  экономичность процесса, вследствие больших удельных затрат тепла на удаление влаги.At the same time, there is a partial burnout of the sediment, which is caused by the clumping and uneven feeding of the sediment, as well as the low efficiency of the process, due to the high specific heat consumption for moisture removal.

Цель изобретени  - улучшение качества нродукдии и повышение экономичности процесса . Эта цель достигаетс  за счет того, что осадок непосредственно перед нодачей на термосушку нодвергают частичному обезвоживанию и диспергированию в центрифуге.The purpose of the invention is to improve the quality of the product and increase the efficiency of the process. This goal is achieved due to the fact that the sediment is immediately subjected to partial dehydration and dispersion in a centrifuge just prior to the submersion to the thermo dryer.

На чертеже изобрал ена принципиальна  схема установки, реализующей предлагаемый способ.The drawing shows a schematic diagram of an installation that implements the proposed method.

Осадок, подлежащий обезвоживанию по трубопроводу } подаетс  в центрифугу 2, где он частично обезвоживаетс  и диспергируетс . Из центрифуги 2 осадок ненрерывно выгружаетс  шнеком в трубопровод 3 подачи теплоносител , куда одновременно подаютс  топочные газы из топки 4. Образовавша с The sediment to be dewatered through a pipeline} is fed to centrifuge 2, where it is partially dewatered and dispersed. From the centrifuge 2, the sediment is continuously discharged by the screw into the heat carrier supply pipe 3, where the flue gases from the furnace 4 are simultaneously fed.

смесь частично подсушенного осадка с топочпыми газами поступает в сушилку 5, где происходит окончательное обезвоживание осадка. Сзхой осадок через течку 6 с затвором удал етс  из сушилки в бункер 7 готового продукта . Отход щие газы по трубопроводу 8 поступают в циклон 9, откуда с помощью дымососа JO по трзбопроводам // удал ютс  в атмосферу.the mixture of partially dried sludge with topochmi gases enters the dryer 5, where the final sludge dewatering occurs. The sludge through the chute 6 with the gate is removed from the dryer to the bunker 7 of the finished product. Exhaust gases through pipeline 8 enter the cyclone 9, from where they are removed by means of a smoke exhauster JO through a three-way pipeline // to the atmosphere.
