In a method of processing paint sludge, measured portions of the sludge are supplied into a heating chamber for pyrolysis at about 1500°F to disintegrate into organic and inorganic portions, the organic portion in the form of syngas is then drawn out, cooled, and pressurized to be used in kilns or combustion chambers, whereas the inorganic portion in the form of ash is directed to a calciner, where it is heated at about 1500°F in a controlled presence of oxygen and cooled to have it ready for the reuse in paint manufacturing.
摘要:
The present technology is generally directed to systems and methods for optimizing the burn profiles for coke ovens, such as horizontal heat recovery ovens. In various embodiments the burn profile is at least partially optimized by controlling air distribution in the coke oven. In some embodiments, the air distribution is controlled according to temperature readings in the coke oven. In particular embodiments, the system monitors the crown temperature of the coke oven. After the crown reaches a particular temperature range the flow of volatile matter is transferred to the sole flue to increase sole flue temperatures throughout the coking cycle. Embodiments of the present technology include an air distribution system having a plurality of crown air inlets positioned above the oven floor.

摘要:
The invention relates to a device on a coal charging car for lifting covers from filling hole frames in the furnace roof of a coke furnace and for cleaning the filling hole frames. The basic design of the device comprises a cover lifter (3) having a supporting arm (4) with a lifting magnet (5), a frame cleaner (6) having a supporting arm (4') with a cleaning head (7), and lifting devices (8, 8') for vertically adjusting the supporting arms (4, 4'). The cover lifter (3) and the frame cleaner (6) can be horizontally displaced by means of a travelling gear (12, 12') between an operating position (A) in which the lifting magnet (5) or the cleaning head (7) is aligned with a filling hole (13) in the furnace roof of the coke furnace, and a rest position (B) spaced apart from the filling hole. The device according to the invention is characterized in that the travelling gear (12, 12') comprises a travelling frame (15) which can be horizontally displaced on tracks (14) on the underside of the coal charging car along a first axis and a supporting frame (16) arranged inside the travelling frame (15), said supporting frame (16) being movably guided on the travelling frame along a second axis at a right angle to the direction of movement of the travelling frame (15), and the lifting devices (8, 8') for the cover lifter (3) and/or the frame cleaner (6) being arranged on the supporting frame.

摘要:
The present technology is generally directed to methods of increasing coal processing rates for coke ovens. In various embodiments, the present technology is applied to methods of coking relatively small coal charges over relatively short time periods, resulting in an increase in coal processing rate. In some embodiments, a coal charging system includes a charging head having opposing wings that extend outwardly and forwardly from the charging head, leaving an open pathway through which coal may be directed toward side edges of the coal bed. In other embodiments, an extrusion plate is positioned on a rearward face of the charging head and oriented to engage and compress coal as the coal is charged along a length of the coking oven. In other embodiments, a false door system includes a false door that is vertically oriented to maximize an amount of coal being charged into the oven.

摘要:
Изобретения могут быть использованы в области промышленной переработки горючих углерод- и углеводородсодержащих продуктов. Способ переработки горючих углерод- и/или углеводородсодержащих продуктов, включает последовательную послойную переработку шихты в реакторе в присутствии катализатора. В реакторе шихта сверху вниз проходит зоны нагрева продуктов переработки (9), пиролиза (8), коксования (7), горения (6) с образованием твердого остатка, который выгружают из зоны выгрузки твердых остатков переработки (2) с выгрузным окном (3) из рабочего пространства реактора циклически с сохранением его герметичности. Герметичная рабочая камера (1) реактора содержит зону подвода влажных мелких частиц отходов твердых топлив и их пиролиза и коксования (14), совмещенную с зонами подвода (4) и нагрева (5) кислородсодержащего агента. Канал подвода кислородсодержащего агента (15) соединен с бункером-дозатором (16) влажных мелких частиц отходов твердых топлив, из которых в зоне (14) реактора формируется псевдоожиженный поток. В реактор вводят дополнительное количество кислородсодержащего агента в составе основного потока, необходимое для последующего горения мелких частиц отходов твердых топлив, прошедших зоны пиролиза (8) и коксования (7), и перевода из влаги в перегретый пар. Изобретения осуществляют полную утилизацию мелких фракций продуктов переработки, позволяют получить высококалорийный газ и увеличить выход и качество готовых продуктов.
