Definitions
- the invention relates to a device for sucking and passing over
- the preamble of claim 9 Such a device is known for example from DE 1 161 847 B.
- Feed opening can severely obstruct the work on the machine side of the oven and is detrimental to health. Since the filling gases contain combustible components, there is also the risk of stinging flame. The contained soot and dust leads to heavy pollution of the environment and atmosphere. In addition, valuable raw materials and residual gases of high calorific value can be obtained from the filling gases. The fullest possible detection of the filling gases is therefore not only health and
- the ramming cake can be damaged by the mechanical contact with the sealing elements, since the sealing elements against the
- the invention is therefore an object of the invention to provide an improved device for the suction of filling gases, which effectively suppresses the formation of filling emissions and low cost, without damaging the rammed cake.
- the object is achieved by a device for suctioning and passing of filling gases from a gas collection chamber of a coke oven chamber, comprising at least one suction hole, which is arranged on the gas collection chamber and through which the filling gases are sucked out of the gas collection chamber, wherein the device has a frame for arrangement a feed opening of the coke oven chamber, the frame forming pressure relief passages, and wherein the pressure relief passages with the at least one suction hole
- the device is characterized by a simple structure. Only one (often already existing) suction hole and an easy-to-produce frame are needed. The frame that the
- Detecting and preventing emissions at the feed opening does not involve any active technical devices, but is completely passive.
- the frame is simple and inexpensive to manufacture. It only has to be adapted to the dimensions of the loading opening. This is the result
- the device according to the invention is very flexible and universally applicable to any coke ovens.
- the emission suppression is non-contact against the stamping cake, so that its surface is not damaged. Since the frame thus does not come into contact with the tamping cake and also has no moving elements, the device according to the invention is very susceptible to damage and reliable in operation.
- the frame has a transfer passage which fluidly connects the pressure relief passages and the gas collection chamber.
- the pressure relief passages may be provided as vertical channels on the sides of the feed opening. These preferably extend over the entire height of the feed opening. In this case, the
- the device comprises a box profile which can be arranged with a side surface on the frame for sealing the device from the outside.
- a further improvement of the seal can be achieved.
- the box profile may be formed by a ramming frame in which the ram cake has been stamped.
- the dimensions of the side surface of the box profile, which can be arranged on the tamping cake from the outside, are preferably equal to or greater than the dimensions of the corresponding
- the box profile covers the opening of the frame and thus blocks the feed opening, so that the emission of filling gases is further suppressed.
- the frame is made of a metal, for example cast metal or steel sheet. This allows a simple and inexpensive production. In addition, it ensures that the frame withstands the high temperature differences that occur in the feed.
- a suction device for the extraction of filling gases from the Gassammeiraum is attached.
- a cross-sectional area of the pressure relief passages is in a range between 0.02 m 2 and 0.25 m 2 . If the cross-sectional area is smaller, the volume provided for the escape of the filling gases is too small and the efficiency of the device is impaired. For larger cross-sectional areas than the specified range increases the required suction power and thus the operating costs. Since in Koksofenbatterien the individual coke oven chambers are arranged close to each other, too large cross-sectional areas are not feasible for reasons of space.
- the Gassammeiraum is limited by a furnace roof of the coke oven chamber.
- the volume below the furnace roof is an advantageous choice for the gas collection room.
- the transfer duct disposed at an upper end of vertical pressure relief passages is a
- the at least one suction hole is arranged in the furnace roof and that a distance between the at least one suction hole in the furnace ceiling and a front edge of the furnace roof at the feed opening of the coke oven chamber in a range between 0.5 m and 5.5 m lies. If the distance is too short, the suction in the pressure relief channels may be too irregular. If the distance is too large, a correspondingly high suction power must be applied in order to maintain a sufficient negative pressure in the pressure relief channels. This leads to higher ones
- the invention also provides a method for preventing filling emissions during the setting of a tamping cake.
- the method according to the invention comprises the following steps:
- sealing method of the present invention By the sealing method of the present invention, leakage of filling gases through the charging port into the atmosphere can be effectively suppressed. Filling gases that exit through the feed opening are sucked in by the negative pressure in the pressure relief channels. This prevents emission of filling gases without requiring mechanical contact with the tamping cake. This effectively prevents damage to the tamping cake while at the same time preventing filling emissions.
- the negative pressure generated in the pressure relief passages is in a range between -50 Pa and -500 Pa. This ensures that the negative pressure is sufficiently high to suck the filling gases into the gas collecting chamber without the filling gases escaping to the atmosphere. A heavier vacuum would unnecessarily increase energy consumption.
- a box member is provided at the end of the tamping cake facing away from the loading opening, which seals the pressure relief channels after complete setting of the tamping cake against the outside. If the charge is such that the ram cake is introduced on a setting plate, which may be formed for example by a bottom plate of the ramming frame, the box element can also serve in addition to the sealing function, the rammed cake at
- Coke oven chamber on both side surfaces and the top of the tamping cake each have a gap between the frame and the tamping cake, whose width is in a range between 0 mm and 30 mm. This ensures that the feed takes place without touching the frame. If the gap is too large, the sealing effect with respect to the atmosphere decreases.
- filling gases which are sucked through the at least one suction hole when setting the tamping cake, are passed via a riser pipe into a gas reservoir and / or via a transfer tube into a neighboring furnace connected thereto.
- the gases are supplied to the gas feedstock, valuable raw materials can be obtained by gas scrubbing.
- the filling gases can first be passed into the gas collection chamber of a neighboring furnace in which little gas is released at this time. The filling gases can then be sucked out of this adjacent furnace via an associated riser and fed to a treatment plant and / or the gas feed.
