Изобретение относитс к области черной металлургии, в частности к устройствам дл подогрева газа, наПример природного, вдуваемого в доменную -печь, а также воздуха, воды и др.The invention relates to the field of ferrous metallurgy, in particular, to devices for heating gas, for example natural, blown into the blast furnace, as well as air, water, etc.
Известно устройСТво дл предварительного подогрева дуть , вдуваемого в печь путем установки теплообменника па газопроводе колошникового газа.A device for preheating a blown blown into the furnace by installing a heat exchanger on a top gas gas pipeline is known.
Недостатком такого устройства вл етс необходимость монтажа таплообменни:ка в газопроводе.The disadvantage of such a device is the need to install a gas exchanger in the gas pipeline.
. С целью использовани физического гелла колошникового газа теплообмепник предлагаемого устройства смонтирован в сухом пылеуловителе доменной печи. При наличии на доменной печи двух пылеуловителей теплообменник предпочтительнее устанавливать во пторичпо.м пылеуловителе.. In order to use a physical flue gas, the heat slug of the proposed device is mounted in a dry blast furnace dust collector. If there are two dust collectors on the blast furnace, it is preferable to install the heat exchanger in a dust collector.
В насто щее в-рем в св зи с посто нным повышением степени подготовки шихтовых материалов дл доменной плавки вынос колошниковой пыли резко снижаетс , таки.м образом, объем сухих пылеу«ювителей, установленных и устанавливаемых на доменных печах, используетс неполностью.At present, due to the constant increase in the level of preparation of charge materials for blast-furnace smelting, the removal of top dust is sharply reduced, and thus, the volume of dry dust of boilers installed and installed on blast furnaces is not fully utilized.
На чертеже показано устройство дл подогрева , например, природного газа, вдуваемого в доменную печь.The drawing shows a device for heating, for example, natural gas blown into a blast furnace.
Устройство состоит из пылеуловител 1, газопровода 2 колошникового газа, газопровода 3 очищенного колощникового газа, газового затвора пулеуловител 4, газопровода 5 подогретого природного газа, теплообменника 6, газопровода 7 холодного газа.The device consists of a dust collector 1, a gas 2 of top gas, a gas pipeline 3 of purified collar gas, a gas seal of a pulley gas 4, a gas pipeline 5 of heated natural gas, a heat exchanger 6, a gas pipeline 7 of cold gas.
Устройство работает следующим образом.The device works as follows.
Поток колошникового газа, идущий из доменной печи с температурой 300-400°С по газопроводу 2 в пылеуловителе 1, омываег те плооб:менник 6 снаружи, природный газ по газопроводу 7 проходит внутри трубок теплообменника 6, где подогреваетс , после чего по газопроводу 5 от1водитс к фурмам домепной печи. Подогрев природного газа позвол ет снизить удельный расход кокса на выплавку чугуна.The flue gas flow coming from the blast furnace with a temperature of 300-400 ° C through the gas pipeline 2 in the dust collector 1, washes the flat: 6 outside, natural gas through the gas pipeline 7 passes inside the heat exchanger tubes 6, where it is heated, then to the furnace furnace tuyeres. Heating natural gas reduces coke consumption for iron smelting.
Предмет изобретени Subject invention
Устройство дл подогрева газа, напри.мер, природного, вдуваемого в доменную печь, выключающее теплообменник и трубопроводы, отличающеес тем, что, с целью использовани физического тепла колошникового газа; теплообмениК смонтирован в сухом пылеулО вителе доменной печи.A device for heating gas, for example, natural, blown into the blast furnace, turning off the heat exchanger and pipelines, characterized in that, in order to use the physical heat of the top gas; Heat exchanger is mounted in a dry dust blast furnace.
