Definitions

  • the invention relates to a device for expressing a coke cake by a coke oven with a double-sided opening.
  • the expression of the coke cake of a coke oven takes place after the end of the fermentation process of a coking cycle.
  • the cooking process may take from 16 to 192 hours, depending on the oven type and process orientation of the plant, by varying the bed height, feed coal mix and oven temperature.
  • the expression is made from the opening of a coke oven side to the other coke oven side.
  • the expressions are usually made with a so-called push rod, which is driven for this purpose on a car in front of the battery to be expressed and is moved by hydraulic devices. After the process of expressing the reloading with coal takes place.
  • the coke oven is preferably a "non-recovery" or “heat-recovery” coke oven, which uses the co-products and coking gases produced during the coking to burn and recover the heat required for coking coke oven chamber but it can also be a conventional, so-called horizontal chamber oven, which absorbs the by-products of the coking process and further processed. Verkokungspro- processes are carried out at temperatures of 800 to 1500 0 C. a considerable part of the heat is stored in the walls and the furnace roof As the combustion of byproducts is usually sufficient to produce the necessary coking energy, it is desirable to minimize the loss of heat during the squeezing process.
  • a print head When expressing the coke according to the prior art, a print head, on which a push rod is attached, pushed by a suitable thruster through the coke oven.
  • the push rod is equipped at its rear end with a device that can exert a compressive force on the push rod.
  • the print head has a plate on the front to protect against the enormous heat of the coke cake.
  • the push rod and printhead are subjected to a considerable heat load in the process of squeezing. As a result, the parts can bend after a short period of operation or material have albruch. For this reason, there are a number of inventions that describe measures against the strong heating of the squeezing device.
  • DE 4224491 A1 describes a device for expressing a coke oven, which consists of a print head and a liquid-cooled push rod.
  • the push rod itself is surrounded by a radiation shield, which surrounds the push rod to the outside at a certain distance and is provided on the inside with cooling coils.
  • a cooling medium which is preferably water or a water-containing liquid.
  • the supply and return of the cooling medium via hose connections.
  • the recooling is carried out via heat exchangers which are connected to the hose connections.
  • the push rod can be formed by T-beams, which are welded, for example, side by side.
  • the device has the disadvantage that the passage of a cooling medium is complicated and prone to failure. For example, leaks in the cooling system can result in unnoticed damage to the squeezing device or the coke oven chamber.
  • DE 840538 C describes a device with a Ausd Wegstange for expressing Kokshuntöfen, which is designed box-shaped and constructed in several parts inside.
  • the push rod is preferably designed in the form of a T-beam. Through the individual parts of the push rod air flows as a cooling medium, which is guided through the rod so that the walls of the rod are always flushed in the same flow direction. As a result, warping the rod is not possible.
  • a printhead is mounted in front, which is not specified in the relevant patent specification.
  • the device cools the push rod, but does not protect the material of the push rod from the intense heat radiation.
  • the design of the push rod depending on the shape of the print head leaves large amounts of cold air of the environment in the coke oven chamber.
  • the push rod is fixed in the center of the print head, so that behind the print head a considerable space remains free, is pressed by the same time when expressing cold air of the coke oven environment in the coke oven chamber.
  • the free space that is forced into the furnace behind the print head adjacent to the push rod emits a considerable portion of the heat stored in the inner coke oven wall to the outside. This represents a considerable heat loss, which must be compensated by the subsequent coking process again.
  • the coal burn is higher and the coke produced is of poorer quality.
  • the push rod Due to the increased heat radiation, the push rod is also exposed to a strong temperature load, which can deform and become brittle after a short period of operation. This is a source of danger because the push rod must absorb strong mechanical forces.
  • the desired device should also prevent cold air from penetrating into the interior of the coking chamber, through which the interior of the coke oven chamber may cool during squeezing and loading, resulting in increased coal consumption and reduced coke quality.
  • a mounted on the printhead baffle which provides the present invention.
  • a baffle or apron is mounted, which covers the push rod almost the entire length.
  • an envelope or enclosure forms around the entire expressing device.
  • the space between the push rod and the enclosure can be left free. But it can also be filled out for better isolation.
  • Glass wool or ceramic fibers are suitable for this purpose, for example.
  • the expressing device takes the form of a cuboid, when the printhead is rectangular and is wrapped on all sides of the enclosure according to the invention. In the interior, the push rod then forms one massive cylinder.
  • the enveloping device is preferably made of a temperature-resistant material.
  • the push rod is protected against the high temperatures of the coke oven chamber and in particular the coke oven walls, which are exposed after expressing the coke. Since the heat capacity and the heating rate of the enclosure is low, the cooling of the coke oven chamber and in particular the coke oven walls is largely prevented. The cold air of the environment can not penetrate to the coke oven walls and thus not cool them. If there is an insulating filling in the interior of the housing, the coke oven walls will remain almost the same temperature if the squeezing process does not last too long.
  • Claimed is in particular a device for pressing out the filling of a coke oven, wherein
  • the device is formed as a push rod in the form of a rod with an oven-side mounted printhead in the form of a plate, and which is characterized in that
  • the printhead is surrounded with mounted rearward baffles or skirts to form an enclosure having the same outer side lengths as the printhead and the outer shape of a square having a uniform cross section when the printhead is rectangular or square; located in the interior pressure rod forms a solid cylinder when it is round in cross-section.
  • the print head has the same cross section as the opening of the coke oven chamber. Then, the outer walls of the enclosure abut exactly on the coke oven chamber walls, so that they are completely shielded from the relatively cold temperatures of the coke oven environment when the contents of the coke oven furnace are pushed out. This allows the process of Koksofenausconces be carried out even in adverse weather conditions.
  • the aprons also protect the rear side of the printhead and the push rod against the high temperatures during squeezing.
  • the printhead may be rectangular or square for use in expressing the coke cake. However, it is also possible to make this round. This is particularly advantageous for a special form of coke oven. It is possible in principle to design the print head in any desired form, if this requires an optimum process of coke ejection.
  • the push rod may have any shape and any cross-section.
  • the push rod is designed as a solid cylinder and round in cross-section. Since the push rod is advantageously mounted in the center of the print head, this forms a solid cylinder in the box or cylinder forming by the housing, depending on the shape of the print head.
  • the push rod can also have any shape for the production of the device according to the invention. So this can be designed as a cuboid.
  • it can also be made of simple, head-mounted T-beams. It is also possible to weld together T-beams and use them as push rods with improved stability.
  • the push rods can be arbitrarily shaped, depending on the requirement of Ausdrückvorganges.
  • the shape that forms the printhead with the mounted enclosure or enclosure in the length of uniform cross-section.
  • the coke oven chamber walls are completely covered by the housing and do not come into contact with the cooler ambient air.
  • this may be tapered or thickened in length and change in cross section. This may be useful, for example, in sensitive secondary air loaf shelves or chambers.
  • the shape may also be irregular in shape if the shape of the coke oven chamber or optimum thermal protection so requires.
  • the entire device for expressing is advantageously formed with the housing in such a way that the process of pushing out the contents of the coke oven chamber is as heat-exchangeable as possible.
  • the baffles may be alsmontiert to manufacture the enclosure according to the invention on all sides of the print head.
  • all oven walls are protected against cooling or cooling down by the simultaneous penetration of cold ambient air.
  • the lower side of the mold may remain free to protect the bottom of the coke oven chamber, which is typically thinner and therefore less robust. It is also possible to protect only one side of the print head with the housing according to the invention.
  • the Aprons can also be of different lengths when an optimal expression process requires it.
  • the aprons or baffles which are used for the construction of the housing according to the invention, can be made of a heat-resistant metallic material. But they can also be made of a ceramic material. It is also possible to make the aprons from a metallic material and to provide it with a ceramic coating. This can advantageously be designed so that it reflects or reflects the heat of the environment.
