Definitions
- the invention relates to a method for reducing Gregasemissions when loading furnace chambers of a coke oven battery with coal cake.
- the driving in of the coal cake in the approximately 1000 ° C hot oven chamber arise spontaneously so-called filling gases that contain harmful components. Unless suitable countermeasures are taken, the opening of the furnace chamber leads to unacceptable environmental pollution.
- the furnace chambers are filled by filling openings in the furnace roof from above with coal, the pressure in the furnace chambers is sometimes regulated individually, the raw gas of the coke oven battery is operated with a slight negative pressure.
- the negative pressure of the raw gas template is used to suck the resulting filling gases and supply the gas treatment. If this method is transferred to coke oven batteries whose furnace chambers are charged with coal cake, the visible emissions during charging of the furnace chambers can indeed be reduced, but this mode of operation leads to inadmissibly high oxygen concentrations in the raw gas.
- DE 2 238 372 also relates to coke oven batteries whose furnace chambers are filled with carbon from filling openings in the top of the furnace.
- the furnace chambers can be optionally connected to two templates, one for withdrawing the production gas and the other for sucking off the filling gases is used.
- the extracted filling gases are dedusted in a gas scrubber and cleaned of tar components.
- the present invention seeks to provide a suitable method for reducing Gregasemissions when loading furnace chambers of a coke oven battery with coal cake.
- the method should be able to suck off as completely as possible the filling gases produced during the setting of the coal cake, so that they do not escape into the atmosphere through the open door of the machine side;
- the process must ensure that as far as possible no atmospheric oxygen enters the raw gas feedstock and thus into the coke oven gas.
- the object of the invention and solution of this problem is a method for reducing filling gas emissions according to claim 1.
- the procedure assumes that the coal chamber to be charged on the machine side of the coke oven battery is opened and a coal cake cake is introduced into the open furnace chamber.
- Filling gases which are released during introduction of the coal cake in the hot oven chamber, according to the invention derived by a connected to the furnace chamber filling gas reservoir and preferably then dedusted and burned.
- Raw gases which are formed during a coking process in the closed furnace chambers, are discharged through a raw gas reservoir connected to the furnace chambers and fed to a gas treatment, which comprises at least one gas scrubber. In the gas scrubber separated components of the raw gas can be further processed into by-products. Connections,
- the inventive method is based in essence on the combination of a conventional raw gas template for the derivation of the raw gases formed by coking and a separate filling gas template, which exclusively serves to extract the filling gases without their transfer into the gas treatment of the raw gas.
- the pressure in the filling gas reservoir is preferably regulated, wherein the suction can be adapted to the local conditions. Since the filling gases are not supplied to a gas treatment in which by-products are produced, an oxygen input into the filling gases is harmless.
- the filling gases are completely burned and then fed to a stationary dedusting device. For this purpose, either a separate dedusting provided or an optionally existing stationary dedusting for the detection of the coke pressures resulting emissions can be used.
- the filling gas template for sucking off the filling gases can be connected to a filling gas suction trolley movable along the coke oven battery.
- the Gregasabsaugewagen can m or with no combustion chamber
- the filling gas reservoir extends as a collecting pipe along the coke oven battery and is connected by branch lines, each with a shut-off device to the furnace chambers of the coke oven battery.
- the shut-off devices are butterfly valves or gate valves with temperature-resistant closing elements or water immersions, which can be opened and closed from the outside.
- the pressure in the closed coke oven chambers is appropriately regulated individually during the coking process.
- the raw gas template may extend as a collecting pipe along the coke oven battery and be connected by branch lines m with a respective shut-off device to the furnace chambers of the coke oven battery.
- the shut-off devices preferably have a dipping cup filled with water and a dip tube connected to the gas-conducting branch line. The liquid level is controlled within the immersion cup, thereby opening or shutting off the gas path.
- the pressure of the associated furnace chamber can be regulated. Regulators for compliance with certain pressure levels in the furnace chambers may also consist of temperature-resistant elements with or without water immersions.
- the raw gas template and the filling gas template can be installed and operated on the same side of the coke oven battery or on different sides of the coke oven battery.
- the raw gas template is arranged on the machine side of the coke oven battery. Here it makes sense to install the filling gas template on the other side, the coke side, the coke oven battery and operate. It is understood that a mirror-image arrangement is possible.
- the invention also provides a suitable for carrying out the method described coke oven battery according to claim 12.
