(54) ТРУБЧАТАЯ ПЕЧЬ(54) TUBULAR OVEN

1one

Изобретение,относитс к нефтехимии и нефтепереработке, в частности к трубчатым печам дл термической переработки нефтепродуктов и других углеводородных смесей.This invention relates to petrochemistry and oil refining, in particular to tube furnaces for thermal processing of petroleum products and other hydrocarbon mixtures.

Известна трубчата печь, содержаща боковые и торцевые стены, потолочное перекрытие, конвективную и радиантную секции продуктового змеевика. На боковых стенах печи расположень ра,аиа1шонные горелки. Радиантна секци продуктового змеевика расположена горизонтально по центру радиантной зоны, образованной боковыми и торцевыми стенами и потолочным перекрытием Г1 .A well-known tubular furnace containing side and end walls, a ceiling, a convective and radiant sections of the product coil. On the side walls of the furnace there is a ra, aa-ashon burners. The radiant section of the product coil is located horizontally in the center of the radiant zone formed by the side and end walls and the ceiling G1.

Эта конструкци печи не экономична с точки зрени использовани топлива на нагрев реакционного-продуктового змеевика , так как с двух сторон змеевик обогреваетс радиационными горелками, в которых сжигаетс качественное топливо , и не дает возмож}юсти сжигать в ней отходы основного производства и другие виды некондиционного топлива.This furnace design is not economical from the point of view of using fuel for heating a reaction-product coil, since the coil is heated on both sides by radiation burners that burn high-quality fuel and does not allow} the main production and other low-grade fuel .

При сжигании отходов основного производства образуютс смолы, которые оседают на наружной поверхности реакционного змеевика и тем самым ухудшаетс теплообмен, а следовательно,и прюизводительность процесса. Удельный расход топлива при этом возрастает.When incineration of the main production wastes, resins are formed, which settle on the outer surface of the reaction coil, and thus the heat exchange and, consequently, the productivity of the process are impaired. The specific fuel consumption increases.

Известна также трубчата печь дл переработки нефтепродуктов, в которой продуктовые трубы размешены в корпусе Also known is a tubular kiln for oil refining, in which product tubes are placed in the body.

10 между внешними и внутренними бокоЕ ыми стенами. На стенах установлены горелки , обогревающие с двух сторон продуктовые трубы 2 .10 between the outer and inner side walls. There are burners on the walls, which heat the food pipes on both sides 2.

Недостатком этой печи вл етс то, The disadvantage of this furnace is that

15 что в ней нельз сжигать жидкое топливо, обеспечив при этом такую же теплоотдачу к трубам. В известной печи сжигаетс газообразное топливо и нет возможности регулировать тепловой прток вдоль 15 that it cannot burn liquid fuel, while providing the same heat transfer to the pipes. In a known furnace, gaseous fuel is burned and it is not possible to regulate the heat flow along

20 змеевика с заданным режимом нагрева.20 coil with a given heating mode.

Claims

The purpose of the invention is to reduce the specific fuel consumption, the use of uncommitted fuels and production wastes, while simultaneously neutralizing them and controlling the heat flow along the product coil. This goal is achieved by the fact that a tubular furnace for processing petroleum products, including groceries. pipes placed between the inner and outer lateral walls, provided with burners, equipped with burners for burning liquid GB located between the inner walls, perforated perforated, and perforated partitions between them. In FIG. 1 shows a furnace, a cross-section; in fig. 2 - a section in plan of internal side walls with partitions.,. The furnace contains two radiant chambers which are formed from the side outer walls 1 and the inner 2, end walls 3 and the ceiling 4. The side walls of the radiant chambers are parallel to each other and the longitudinal axis of the furnace. In the radiant chambers along its side walls 1 and 2, product tubes 5 are installed, made in the form of a two-way screen attached to the ceiling CTeijbi 2 radiant chambers are perforated. Between the perforated walls 2, perforated partitions 6 are installed. In the ceiling cover 7, burners 8 are installed for burning liquid fuel. Radiation torches 9 are installed on the outer side walls 1, designed to burn gaseous fuel. Two convection chambers are made in the lower part of the furnace under the radiant chambers. Convective coil Y. The furnace works as follows. Liquid raw materials are fed under pressure to a convective coil, where it is heated by waste gas. Then it enters the product tubes 5, heated on one side by burning fuel gas in the radiation burners on the other side, the tubes 5 are heated by the heat radiated by the perforated wall 2 as a result of fuel burned in the burners 8 installed in the ceiling 7. Different types of fuels are used, including the possible burning and harmful hydrocarbon waste. The flue gases are vented through the holes in the perforated walls 2, and they heat the walls. The heat accumulated by the perforated walls is transferred by radiation to the product tubes 5, which reduces the consumption of gas burned by the radiation burners 9. Formula of the invention , in order to use non-conforming types of fuel and production wastes with their simultaneous neutralization, it is additionally equipped with burners for burning one fuel arranged between the inner walls, made perforated and placed between these walls perforated baffles.
