Description

석탄 열분해 처리장치Coal pyrolysis processing equipment

본 발명은 열교환 기술분야에 관한 것이고, 구체적으로 석탄 열분해 처리 장치에 관한 것이다.TECHNICAL FIELD The present invention relates to the field of heat exchange technology, and more particularly, to a coal pyrolysis treatment apparatus.

석탄의 열분해 설비는 최종 산물에 대한 요구에 따라, 열분해 설비도 크게 상이하고, 콜타르 산율도 크게 상이하며, 예를 들어, 코크스를 제조하기 위한 코크스로 및 반성코크스를 생산하기 위한 반성코크스로는 로 타입 면에서 크게 상이하고, 코크스로에서 제조된 코크스의 휘발 성분이 비교적 낮으며, 콜타르 산율이 낮으나 석탄 가스량이 크고, 반성코크스로에서 제조된 반성코크스는 휘발 성분이 비교적 높고, 콜타르 산율이 상대적으로 높으며, 석탄 가스량이 다소 낮고, 석유 전략의 필요에 따라, 최근 오일 생산율이 높은 저온 콜타르를 생산하기 위한 회전로가 각광을 받고 있다. 출원번호가 201010262786.6이고, 공개번호가 CN101985558인 석탄 물질의 분해 설비에 관한 특허에서 재료 투입구 및 재료 토출구가 마련되어 있는 밀폐된 가마 본체를 포함하고，상기 가마 본체 내에 화염 파이프 가열기구가 설치되어 있으며, 상기 화염 파이프 가열기구와 가마 본체 내벽 사이에 석탄 물질 분해 추진 통로가 설치되어 있고, 상기 가마 본체에는 석탄 물질 분해 추진 통로에 연통되는 석탄 분해 가스 수집관이 설치되어 있는 석탄 물질의 분해 설비를 공개하였다. 당해 발명은 화염 통로 가열기구에서 생성된 대량의 열을 석탄 물질 분해 추진 통로의 석탄 분말에 전달하고 열복사하여, 석탄 분말이 열을 충분히 흡수하여, 온도가 상승하여 분해됨으로써 석탄 물질 추진 분리 통로 내에서 가스, 타르 가스 및 발열량이 비교적 높은 석탄으로 분해되고, 가스 및 타르 가스는 상기 석탄 분해 가스 수집관을 통해 회전로 외부의 기체 제진 액화기구에 연결되어, 분해된 가스, 타르 가스에 대해 제진, 분리 및 가압 액화를 진행한다.The pyrolysis plant of coal varies greatly depending on the requirements of the final product, the pyrolysis plant and the coal tar acid rates are also very different. For example, the coke furnace for producing coke and the semi-coke for producing semicoke are In terms of type, the volatile components of coke produced in coke oven are relatively low, the coal tar acid rate is low, but the amount of coal gas is high, and the semi-coke produced in semi-coke oven is relatively high in volatile component, and the coal tar acid rate is relatively high. Higher, somewhat lower coal gas, and the need for petroleum strategy, the rotary furnace for producing low-temperature coal tar with high oil production rate is in the limelight. Patent No. 201010262786.6 and Patent No. 1010558558 disclose a coal material decomposing facility comprising a closed kiln body is provided with a material inlet and a material outlet, the flame pipe heating mechanism is installed in the kiln body, The coal material decomposition propagation path is provided between the flame pipe heating mechanism and the inner wall of the kiln body, and the coal material decomposition facility in which the coal decomposition gas collection pipe communicating with the coal material decomposition propulsion path is provided is disclosed. The present invention transfers a large amount of heat generated by the flame passage heating mechanism to the coal powder in the coal decomposition cracking propagation passage and heat radiation, so that the coal powder absorbs the heat sufficiently, and the temperature rises and decomposes so as to decompose in the coal mass propulsion separation passage. Gas, tar gas and calorific value are decomposed into coal, which has a relatively high calorific value, and the gas and tar gas are connected to the gas dedusting liquefaction mechanism outside the rotary furnace through the coal cracking gas collection pipe, to dedust and separate the decomposed gas and tar gas. And pressurized liquefaction.

상술한 특허는 오일 생산율 방면에서 확실히 비교적 높고 시범적이나, 당해 특허는 타르 생산율을 가능한 한 최대로 높이는 것만 고려하고, 이러한 저온 열분해로 인해 초래되는 개질 후의 석탄에 휘발 성분이 여전히 비교적 많은 점 및 석탄 가스량에 대한 콜타르 수소화의 수요를 고려하지 않았다. 상술한 특허는 콜타르 산율이 높을 시 석탄 가스량이 낮거나 또는 가스 생산량이 높을 시 콜타르 산율이 낮을 수 있어 양자를 겸하여 고려할 수 없다는 한계가 있다.The above-mentioned patents are certainly relatively high and pilot in terms of oil production rate, but the patent only considers the highest possible tar production rate and considers that there is still a relatively high amount of volatile components in the coal after reforming caused by such low temperature pyrolysis and the amount of coal gas. The demand for coal tar hydrogenation was not taken into account. The above-described patent has a limitation in that coal gas content may be low when the coal tar acid rate is high or coal tar acid rate may be low when the gas production rate is high, so that both may not be considered.

이에 감안하여, 본 발명은 기존 기술의 부족점을 개선하기 위한 것이며 효율 높은 가스 생산 및 콜타르 생산을 동시에 고려할 수 있는 석탄 열분해 처리장치를 제공하는 것을 목적으로 한다.In view of this, an object of the present invention is to improve the shortcomings of the existing technology, and an object of the present invention is to provide a coal pyrolysis treatment apparatus capable of simultaneously considering high-efficiency gas production and coal tar production.
