Изобретение относитс к черной металлургии и предназначено дл подогрева очищенного газа и охлаждени пара установок испарительного охлаждени .The invention relates to ferrous metallurgy and is intended to preheat the purified gas and to cool the vapor of evaporative cooling units.
Цель изобретени - увеличение степени утилизации тепла параThe purpose of the invention is to increase the degree of heat recovery of steam.
На чертеже изображена принципиальна схема предпагаемого устройства . ,The drawing shows a schematic diagram of the device being intended. ,
Устройство содержит теплообменннкрекуператор 1 с секци ми, установленный на газопроводе 2 от доменной печи 3 и мокрой газоочистки 4 к утилизатору 5, которым вл етс , например , энергетический парогенераторThe device contains heat exchanger section 1, installed on the gas pipeline 2 from the blast furnace 3 and wet gas cleaning 4 to the utilizer 5, which is, for example, an energy steam generator
Устройство работает следующим образом .The device works as follows.
Теплообменник-рекуператор 1 имеет секции q уВ и Ь , подключенные к паропроводам с давлением 1,2-13 ата. Например, в секции И доменный газ . греетс паром установки испарительного охлаждени доменных печей давлением 1,2 ата до 105с, В секции о. доменный газ нагреваетс паром уста3512Heat exchanger-heat exchanger 1 has sections q уВ and b, connected to steam pipelines with a pressure of 1.2-13 at. For example, in the section AND blast furnace gas. It is heated by the steam of an evaporative cooling plant for blast furnaces with a pressure of 1.2 atmospheres to 105 s. the blast furnace gas is heated by steam.
новок испарительного охлаждени мартеновский печей давлением 7 ата до бАс. В секции S - паром давлением 12-13 ата до 187°С, Таким образом, по ходу доменного газа, секции подключают по все более высокому давлению пара,Novokova evaporative cooling of open-hearth furnaces with pressure of 7 ATA to bАС. In section S - with steam pressure of 12-13 at to 187 ° С. Thus, along the course of blast furnace gas, the sections are connected to an ever higher vapor pressure,
В общем случае количество секций зависит от схемы паропроводов низкогоIn general, the number of sections depends on the scheme of low steam lines
давлени конкретного металлургичес кого завода и параметров пара, вырабатываемого установками испарительного охлаждени печей и отбора турбин ,the pressure of a particular metallurgical plant and the parameters of steam generated by the evaporative cooling of furnaces and the selection of turbines;
В летнее врем пар установок испарительного охлаждени и часть отбора турбин используетс дл на- грева доменного газа, В зимнее врем , в зависимости от теплового баланса конкретного производства, теплообменники 1 остаютс в работе или часть секций по пару отключаетс . Таким образом секционирование теплообменника I позвол ет болееIn the summertime, steam of the evaporative cooling units and part of the turbine extraction is used to heat the blast furnace gas. In wintertime, depending on the heat balance of the specific production, heat exchangers 1 remain in operation or part of the steam sections are disconnected. Thus, the partitioning of the heat exchanger I allows more
гибко использовать его в течение года.flexibly use it throughout the year.
