Изобретение относнтс к домешюмуThe invention relates to homemade
производству, в частности дл подачи дутьевых добавок через фурменный хфибор в доменную печь.production, in particular for the supply of blast additives through the tuyere collection in the blast furnace.
Известен способ и устройство дл регулщюванн глубины расхфостраненн .5There is a known method and device for regularizing depths of dry grains .5
, дуть , в котором дополнительное топливо по раднально расположенным трубкам и через топливный расщ еделитель, имеюпщй вихревую форсунку, подаетс в поток дуть , blowing, in which the additional fuel is distributed through radially arranged tubes and through the fuel rail, the divider, which has a vortex nozzle, is blown into the flow
В таком устройстве можно достичь желаемых результатов распределени в смешивани дутьевых добавок в потоке дуть , однако даже при кратковременном отключени дутьевой добавки, что необходимо вы- 5 полн ть остановке доменной пёчв, топ ливный распределитель с вюфевой фсфсункой по действием высокой температуры газов разрушаетс .In such a device, it is possible to achieve the desired distribution results in the mixing of blast additives in the flow to blow, however, even with a brief shutdown of the blast additive that it is necessary to stop the blast furnace, the fuel distributor with the HPF element is destroyed by the high temperature of the gases.
Наиболее близким к изобретению по технической сущности и достигаемым результатам вл етс сопло фурменного прибора доменной печи, содержащее форсункуThe closest to the invention to the technical essence and the achieved results is the nozzle of the blast furnace tuyere stockpile containing the nozzle
дл вдувани мазута по осв сопла, котора снабжена расположенной на рассто нии от двух до трех его диаметров от переднего торца пoпqpeчнoй водоохлаждаемой перегч} родкой каплевидной формы, в которую встроена форсунка .Недостатками известного ссмша вл ютс ограничение объемноги расхода дутье- вой добавки, особенно газообразной, из-за малого дйаметра патрубка, так как с ув&личением его диаметра уменьшаетс 1фопускное сечение фурменного прибсра; возгорание дутьевой добавки в месте сочленени сопла и фурмы с выходом пламени за пределы фурменного прибора, фичем в месте сочленени сопла с фурмой возрастает температура, что приводит к перегреву неохлаждаемой поверхности сопла и образованию щ одувов.for injection of fuel oil by the end of the nozzle, which is equipped with a distance from two to three diameters from the front end of the intermediate water-cooled superheater} drop-like shape into which the nozzle is embedded. The disadvantages of the known smsh are limiting the amount of flow of the blowing additive, especially gas , because of the small diameter of the nozzle, since with the diameter of its diameter the 1focus section of the tuyere pribr decreases; Ignition of the blast additive at the junction of the nozzle and the tuyere with the flame coming out of the tuyere device, the temperature at the junction of the nozzle with the tuyere increases, which leads to overheating of the uncooled nozzle surface and the formation of gas.
