本発明はコークス乾式消火の技術分野に関して、特に、コークス乾式消火用除塵装置、及びコークス乾式消火ボイラの蒸気収率を向上させる方法に関している。 TECHNICAL FIELD The present invention relates to the technical field of coke dry quenching, and more particularly to a dust removal device for coke dry quenching and a method for improving the steam yield of a coke dry quenching boiler.
コークス乾式消火のプロセス過程で、赤熱コークスをコークス炉の天井部から入れて、低温の不活性ガスは循環送風機から、コークス炉の冷却部の赤熱コークス層内に送風され、赤熱コークスの顕熱を吸収し、冷却後のコークスはコークス炉の底部から排出され、コークス炉の環状煙道から排出された高温の不活性ガスはコークス乾式消火ボイラを経由して熱交換を行って、コークス乾式消火ボイラから蒸気を発生させ、冷却後の不活性ガスは循環送風機によって、改めてコークス炉に送風され、密閉システム内で循環使用される。一般的に、高温の循環ガスは一次除塵機を介して粗いコークス粉を分離させられた後、コークス乾式消火ボイラに入って熱交換を行って、温度が約１６０℃に低下した低温の循環ガスはコークス乾式消火ボイラから排出され、二次除塵機を介して細いコークス粉をさらに分離させられた後、循環送風機によって、給水予熱器に送られて、約１３０℃まで冷却されてから、コークス炉に入って循環使用される。 In the process of coke dry quenching, the red hot coke is put into the coke oven ceiling, and the low temperature inert gas is blown into the red hot coke layer in the cooling part of the coke oven from the circulation fan, and the sensible heat of the red hot coke is The coke after absorption and cooling is discharged from the bottom of the coke oven, and the hot inert gas discharged from the annular flue of the coke oven undergoes heat exchange through the coke dry quenching boiler, and the coke dry quenching boiler Steam is generated from the coke oven, and the inert gas after cooling is blown again to the coke oven by a circulation fan, and is circulated within the closed system. In general, high-temperature circulating gas passes through a primary dust remover to separate coarse coke powder, and then enters a coke dry-extinguishing boiler to perform heat exchange. is discharged from the coke dry quenching boiler, fine coke powder is further separated through the secondary dust remover, sent to the feed water preheater by the circulation fan, cooled to about 130 ° C, and then coke oven are used cyclically.
一次除塵機は循環ガスにおける大粒子のコークス粉を分離させ、循環ガスの、ボイラ配管に対するフラッシング摩耗を低減させる。現在、一次除塵機により分離されたコークス粉は主に、焼結、再配合コークス製造及びコークス化除塵灰系活性炭の製造などに用いられるが、分離されたコークス粉の品質が低く、エネルギー消費が高く、または技術レベルに制限があるため、このようなプロセスによる経済的利益は有限であり、環境汚染を招致しやすい。 The primary dust remover separates large particles of coke dust in the circulating gas to reduce flushing wear of the circulating gas to the boiler piping. At present, the coke powder separated by the primary dust remover is mainly used for sintering, recombined coke production and coking dust-removed ash-based activated carbon production. Due to high or technical level limitations, such processes have limited economic benefits and are prone to environmental pollution.
本発明は、除塵機の下方に設けられるバーナーを利用して、除塵機から沈下したコークス粉を十分に燃焼させ、発生した大量の熱煙ガスを循環ガスに導入し、コークス乾式消火ボイラにより多くの蒸気を発生させ、これによって、より大きな経済的利益を取得するコークス乾式消火用除塵装置、及びコークス乾式消火ボイラの蒸気収率を向上させる方法を提供する。 The present invention uses a burner installed below the dust remover to sufficiently burn the coke powder that has settled down from the dust remover, introduces a large amount of generated hot smoke gas into the circulating gas, and increases the coke dry fire extinguishing boiler. steam, thereby obtaining greater economic benefits, and a method for improving the steam yield of a coke dry fire boiler.
