Description
Technical field
The present invention relates to a kind of chimney zero meter of surface drainage system, particularly a kind of single-drum chimney zero meter of surface drainage system and apply method.
Background technology
Single-drum chimney is simple with its construction, short construction period, and the low feature of cost is by wide selection.But along with the employing of coal-burning power plant's wet desulfurizing process, the cancellation of bypass flue and flue gas heating system, the flue-gas temperature of discharging from single-drum chimney reduces greatly, substantially remains on about 50 DEG C.In addition, when a flue high position is arranged, dust stratification platform imperviously constitutes larger hidden danger for the entirety of chimney is anticorrosion, cancels dust stratification platform and becomes main trend.Therefore, the condensation sour water that have employed a large amount of low-temperature flue gas in the single-drum chimney of wet desulfurizing process and cancellation dust stratification platform can from cylinder head along cylinder inboard wall downstream to zero meter face, and the condensation water quantity in usual chimney can reach several tons per hour.Therefore, chimney zero meter face, as the key position of single-drum chimney dust stratification and draining tissue, carries the inner discharge of all acid solutions of chimney and the accumulation task of dust.Existing single-drum chimney zero meter of draining tissue is made up of steel concrete acid solution collecting pit, annular draining ramp, deashing passage and drainage pipe four part.In zero meter of drainage system of this structure, acid solution could import in the acid solution collecting pit in zero centre, meter face downstream to flowing through annular ramp behind chimney zero meter face again through barrel, and then from collecting pit, connects ejectment through drainage pipe go out chimney.In such drainage system, acid solution can not when flowing to zero meter face the very first time be discharged to outside cylinder; When cigarette ash comes together in acid solution collecting pit in a large number with acid solution, cigarette ash through precipitation also easily causes the blocking of drainage pipe at the bottom of acid solution collecting pit, make zero meter of land drainage organization system impeded drainage, therefore often need carry out deashing work to the drainage system in zero meter face, again because of deashing passage and deashing narrow space, the operation of fortune ash deashing is met difficulty.
