BACKGROUND OF THE INVENTION In a coke dry fire extinguishing apparatus (hereinafter, referred to as a kiss: c〇ke Dry Quencher), as disclosed in Japanese Patent Laid-Open Publication No. 9-9 No. Processing the chamber and lowering it to the cooling chamber, and supplying the inert gas as a cooling gas from the lower portion of the cooling chamber to the chamber to exchange heat with the hot coke, and introducing the hot high-temperature inert gas that has recovered the hot coke into the waste hot-spinning furnace The heat exchange was carried out, and then the exhaust gas from the waste hot steel furnace was again blown to the cooling chamber by a circulation blower to perform 15 cycles. The steam obtained by heat exchange in the waste heat boiler is used to drive the generator and is recovered as an electric energy source. Fig. 8 is a plan view of a conventional CDQ, and Fig. 9 is a front view (a side view seen from C-C of Fig. 8), and Fig. 1 is a side view seen from d-d of Fig. 8. In Figures 8 to 10, the CDQ gas circulation system is connected to the gas circulation blower 8, the cooling tower i, the secondary dust collector 3, the waste hot steel furnace 2, and the secondary dust remover 6' by The gas pressurized by the gas circulation blower 8 passes through the cooling tower 1 - the primary dust remover 3 - the waste heat boiler 2 - the secondary dust remover 6 is again boosted by the gas circulation blower 8 and sent to the cooling pull 1 . In order to reduce the installation space between the waste heat boiler outlet conduit and the suction side of the gas circulation blower 1258502, the gas flow of the conventional gas circulation system is generally divided into two systems, and further, in order to make the waste heat boiler outlet conduit to the suction side of the gas circulation blower The system becomes 2 systems, and the piping resistance of the two systems is the same. The position of the gas circulation blower is directly below the primary dust collector. In the conventional CDQ, since the gas circulation blower 8 is disposed directly under the primary precipitator 3 and the dust collecting machine is disposed at the upper portion, the space above the circulating blower becomes small, which is obviously disadvantageous to the maintainability of the blower. Moreover, considering the large-scale trend of CDQ in recent years, the problem of narrow space will become an increasingly serious problem. Furthermore, since the waste heat boiler outlet 10 pipe is connected to the gas circulation blower as two systems, the gas conduit of the passage must be of two types, and the secondary dust collector must also have two, so that the non-fit will not be met. Economic benefits. Therefore, the present invention provides a CDQ which can improve the maintainability of a CDQ gas circulation blower while constituting a gas circulation system in an economical configuration. SUMMARY OF THE INVENTION The present invention relates to a coke dry fire extinguishing apparatus, which is connected to a cooling tower, a primary dust remover, a waste heat boiler, a secondary dust remover, a gas circulation blower 20, and the aforementioned cooling tower, and is used to cool the heat. The coke gas flow is sequentially passed through the closed circuit of each of the machines to form a circulating gas flow path, wherein the gas flow path from the lower portion of the waste heat boiler to the secondary dust remover is one piece, and is connected to the foregoing A portion of the gas flow path in the lower part of the waste heat boiler is provided with a rectifying plate. 1258502 Further, the discharge direction of the gas flow path from the lower portion of the waste heat boiler to the secondary dust remover may be parallel or at right angles to the gas flow path from the primary dust collector to the upper portion of the waste heat boiler.
