Abstract
The present invention relates to adding biomass, more precisely sucrose, which can be sugar, soy molasses, sugar cane molasses or another type of molasses, to the water used in the process of quenching coke that is produced in vertical or horizontal furnaces. The biomass may be added manually or automatically, i.e. the sugar and/or molasses is added to the container holding the water and the mixture is produced by diluting the biomass in the water. The percentage of biomass added to the water is between 5 and 30%. The carbon present in the biomass is deposited on the surface of the coke lumps, resulting in an increase in the impact and abrasion strength (an increase in the Drum index or Micum) of the coke, which reduces breaking up of said coke lumps during handling from the production site to the consumer. Said increase in the strength of the coke lumps has the benefit of resulting in an increase in the average size of the lumps, reducing the emission of fine particles into the atmosphere. Said increase in the average size of the coke lumps leads to improved pig iron production in a tall furnace.
Description
"AUMENTO DA DUREZA E RESISTÊNCIA AO IMPACTO E A ABRASÃO DO COQUE ATRAVÉS DA MISTURA DE BIOMASSA (SACAROSE; MELAÇO DE SOJA;MELAÇO DE CANA DE AÇÚCAR E OUTROS TIPOS DE MELAÇO) COM A ÁGUA DE APAGAMENTO DO COQUE PRODUZIDO EM FORNOS VERTICAIS E HORIZONTAIS". "INCREASING THE HARDNESS AND RESISTANCE TO THE IMPACT AND ABRASION OF COCK THROUGH BIOMASS MIXTURE (SACAROSE; SOY MOLASS; SUGAR MOLASS AND OTHER TYPES OF MOLASS) WITH COKE-CLEARING WATER AND" VERTICAL HORNES " .
A presente patente de modelo de utilidade tem por objetivo a aplicação da mistura composta de água e sacarose (melaço de soja e ou de cana de açúcar) no processo de apagamento e ou transporte por correias transportadoras do coque produzido em coquerias (fornos verticais ou horizontais), utilizado como matéria prima na produção de ferro gusa em alto forno. O coque sai do forno da bateria em torno de 1 100 °C e ao receber a mistura da água com a sacarose ocorre a deposição do carbono da sacarose na superfície das pedras de coque. Além de ocorrer essa deposição, há também a reação entre o carbono da estrutura do coque com o carbono da biomassa. Esse carbono adicionado promove um aumento de dureza superficial nas pedras de coque. The present utility model patent aims at the application of the mixture of water and sucrose (soy molasses and sugar cane molasses) in the process of deletion and or conveyor conveyor of coke oven (vertical or horizontal ovens). ), used as a raw material in the production of pig iron in a blast furnace. The coke comes out of the battery oven around 1,100 ° C and upon receiving the water and the sucrose mixture the sucrose carbon is deposited on the surface of the coke stones. In addition to this deposition, there is also the reaction between the coke structure carbon and the biomass carbon. This added carbon promotes an increase in surface hardness in coke stones.
A elevação da dureza superficial das pedras de coque proporciona uma maior resistência superficial desse material ao impacto e a abrasão, o que faz reduzir a degradação no transporte e a elevação do tamanho médio desse material, como também a redução da emissão para a atmosfera de particulados finos que se desprendem das pedras de coque. Increasing the surface hardness of coke stones provides greater surface resistance of this material to impact and abrasion, reducing transport degradation and increasing the average size of this material, as well as reducing particulate emissions to the atmosphere. thin ones that come off the coke stones.
O coque produzido em forno vertical e forno horizontal esta com temperatura que varia entre 1000 e 1000 C e o apagamento desse coque é feito com água, reduzindo essa temperatura para a faixa de 30 a 70 C. No processo de apagamento, é utilizada mangueiras ou a água é bombeada até um reservatório feito de concreto ou de metal, e a um detem inado intervalo de
tempo ocorre o banho para resfriar as pedras de coque dentro de um cairo denominado de cairo de apagamento. Essa água é descarregada no cairo de apagamento através de chuveiros (furos em tubulações) posicionados acima do cairo de apagamento. Com o banho, as pedras de coque, trocam calor e parte dessa água será evaporada (cerca de 10%) e esse vapor é liberado para a atmosfera. A água restante é recirculada retornando para o reservatório, onde será utilizada novamente no apagamento seguinte. The coke produced in a vertical oven and a horizontal oven has a temperature ranging from 1000 to 1000 C and the coke is blown out with water, reducing this temperature to the range of 30 to 70 C. In the process of blasting, hoses are used or the water is pumped into a reservoir made of concrete or metal, and at a certain interval of The bath takes place to cool the coke stones inside a cairo called the erasing cairo. This water is discharged into the erasing stream through showers (pipe holes) positioned above the erasing stream. With the bath, the coke stones exchange heat and some of this water will be evaporated (about 10%) and this steam is released to the atmosphere. The remaining water is recirculated returning to the reservoir where it will be used again for the next deletion.
A utilização da água como fluido de apagamento das pedras de coque nas coquerias não produz melhora da qualidade das pedras e sim, produz choque térmico, pois reduz bruscamente a temperatura das pedras o que gera trincas nas mesmas. The use of water as a coke stone extinguishing fluid in the coke oven does not improve the quality of the stones, but produces thermal shock, because it sharply reduces the temperature of the stones which generates cracks in them.
As coquerias mais antigas fazem o apagamento do coque com a utilização de mangueiras ou equipamentos manuais, más todas utilizam 100% água como fluido de apagamento. Para esses casos a sacarose ( melaço de soja ou cana de açúcar e outros) devera ser misturada a água de apagamento, seja manualmente ou automaticamente. Older coke ovens erase coke using hoses or hand-held equipment, but all use 100% water as an extinguishing fluid. For such cases sucrose (soya molasses or sugar cane and others) should be mixed with extinguishing water either manually or automatically.
E objetivo da invenção presente a adição dessa biomassa aos processos mencionados acima, como também reduzir a emissão de partículas (finos de coque) à atmosfera. It is an object of the present invention to add such biomass to the above mentioned processes, as well as to reduce the emission of particles (coke fines) to the atmosphere.
A invenção está baseada na utilização da mistura de água com sacarose e ou melaço de soja, como também melaço de cana de açúcar no processo de apagamento do coque, o que resulta na deposição de uma camada composta de 100% carbono orgânico na superfície das pedras de coque, carbono esse, oriundo das reações do carbono do coque com o carbono do melaço (figura 1). Essa camada por possuir maior dureza, proporcionara maior resistência mecânica às pedras de coque ao impacto e a abrasão e consequentemente menor nível de degradação desse coque no transporte seja por correias transportadoras ou por caminhões, entre a coqueria e o local de destino. O resultado final do processo de apagamento do coque com a mistura acima será: The invention is based on the use of sucrose and / or soy molasses water mixture as well as sugar cane molasses in the coke erasing process, which results in the deposition of a layer composed of 100% organic carbon on the surface of the stones. coke, this carbon, derived from the reactions of coke carbon to molasses carbon (figure 1). This layer, due to its hardness, will provide greater mechanical resistance to coke stones to impact and abrasion and consequently lower level of degradation of this coke in transport, whether by conveyor belts or trucks, between the coke oven and the destination. The end result of the coke deletion process with the above mixture will be:
1- Maior tamanho das pedras de coque;
2- Redução da emissão de partículas finas de coque à atmosfera; 1- Larger size of coke stones; 2- Reduction of the emission of fine coke particles into the atmosphere;
3- Aumento da resistência ao impacto e a abrasão, ou seja aumento a resistência mecânica a frio do coque (Drum índex ou Micum). 3- Increased impact and abrasion resistance, ie increased cold mechanical resistance of the coke (Drum Index or Micum).
4- Melhora do desempenho do coque no interior do alto forno e consequentemente na produção do ferro gusa. 4- Improvement of coke performance inside the blast furnace and consequently in the production of pig iron.
A adição da sacarose (açúcar) ou melaço na água de apagamento do coque poderá ser feita nas seguintes faixas: The sucrose (sugar) or molasses may be added to the coke extinguishing water in the following ranges:
1- 5 a 10% 1-5 to 10%
2- 10 a 20% 2-10 to 20%
3- 20 a 30% 3-20 to 30%
Quanto maior for a adição da sacarose (açúcar) ou do melaço na água de apagamento do coque, maior será a espessura da camada superficial depositada nas pedras de coque e melhor será a sua resistência ao impacto e a abrasão. The more sucrose (sugar) or molasses is added to the coke extinguishing water, the greater the thickness of the surface layer deposited on the coke stones and the better the impact and abrasion resistance.
Além do fato acima, é importante considerar que o carbono orgânico depositado sobre a superfície das pedras de coque, aumenta o teor de carbono das mesmas, carbono esse consumido no processo de fabricação do ferro gusa e favorece a redução de emissão de C02 para a atmosfera, devido ao mesmo não ser proveniente da queima do carvão mineral. In addition to the above, it is important to consider that the organic carbon deposited on the surface of coke stones increases the carbon content of the coke stones, which carbon is consumed in the pig iron manufacturing process and favors the reduction of CO2 emissions to the atmosphere. , because it does not come from burning coal.
Não existe efeito colateral negativo ao meio ambiente no processo de adição da sacarose (açúcar) e ou do melaço no apagamento e no transporte do coque, visto que se trata de um composto orgânico sem danos. There is no negative side effect to the environment in the process of adding sucrose (sugar) and / or molasses in the coke deletion and transport, since it is an undamaged organic compound.
