Abstract

"MéTODO E SISTEMA PARA SOPRO DE CIRCULAçãO DE CDQ". A presente invenção refere-se a um método para sopro de circulação de extintor a seco de coque (CDQ) capaz de iniciar sem usar um soprador de circulação dimensionado pequeno acionado eletricamente no momento de iniciar, mas usando um soprador de circulação acionado por uma turbina a vapor usada em operação estável, e um sistema de sopro de circulação simplificado em recursos é fornecido, isto é, um método de sopro de circulação de CDQ executando a troca de calor entre o coque quente rubro carregado para um corpo de CDQ 1 e um gás inerte introduzido debaixo do dito corpo de CDQ 1, recuperando o calor latente do gás inerte depois da troca de calor em um boiler 4, e introduzindo o gás inerte resfriado pela recuperação do seu calor latente no boiler 4 no corpo de CDQ 1 outra vez para circulação, que produz vapor, a fonte de acionamento para acionar o dito soprador de circulação 5, introduz vapor de uma fonte de suprimento de vapor fornecida separadamente 18 quando está iniciando o CDQ, e introduz vapor de uma tubulação de bypass 17 ramificada de uma tubulação de vapor 13 do boiler 4 depois que o CDQ termina de dar partida."CDQ CIRCULATION BLOWING METHOD AND SYSTEM". The present invention relates to a method of coke dry fire extinguisher (CDQ) circulation blowing capable of starting without using an electrically actuated small sized circulating blower but using a turbine driven circulation blower. steam system used in stable operation, and a resource-simplified circulation blowing system is provided, that is, a CDQ circulation blowing method by performing heat exchange between the red hot coke charged to a CDQ body 1 and a inert gas introduced under said CDQ body 1, recovering the latent heat of the inert gas after heat exchange in a boiler 4, and introducing the cooled inert gas by recovering its latent heat in boiler 4 in the CDQ 1 body again for circulation, which produces steam, the drive source for driving said circulation blower 5 introduces steam from a separately supplied steam supply source 18 when is starting CDQ, and introduces steam from a branched bypass pipe 17 from a steam pipe 13 from boiler 4 after the CDQ finishes starting.
