Definitions

  • the invention relates to a method for limiting the emissions from the operation of coking furnace batteries by vacuuming the emissions with tar-containing dust at the respective emission sources, such as. B. when charging coal into the ovens, at the coking oven doors and when coke is being squeezed, into stationary gas manifolds with subsequent dry dedusting in a bag filter system and with cleaning the filter by introducing compressed air.
  • the filter bags should be cleaned in such a way that compressed air is blown into a room above the filter, which is then to flow into the room around the entire filter and from there into the interior of the tubular filter, the filters should be vibrated at the same time because of the resilient suspension.
  • Such a cleaning process can only be carried out in one phase if no emissions are extracted, since the entire available suction is reduced by the back pressure of the compressed air.
  • the task of the compressed air in the entire filter housing has a gradual effect on the individual bag filter walls, so that the bag filters are only slowly vibrated and the entire cleaning process is not very intensive. It requires a considerable amount of time.
  • the object of the invention is therefore to propose a method of the generic type with which all tar-containing dusts can be removed from the bag filter surfaces more quickly and more effectively and thus all emission gases occurring in the coking plant can be cleaned in the bag filter system.
  • the invention provides that all filter bags in a bag filter row are cleaned simultaneously and the individual bag filter rows are cleaned one after the other by a short burst of compressed air from the injector.
  • the successive task of the injector compressed air blast on the individual bag filter rows may also be able to clean only a small part of the bag filter even in only a short period of time and then interrupt cleaning if, for example, a coke pushing out operation is expected contrary to expectations.
  • the pressure operation of the coking ovens at the coking plants is therefore in no way hindered by the cleaning of the bag filter system.
  • the filter system remains. an ancillary system that can be based on the accumulation of dust emissions.
  • the hose filter chambers Stalten e-the degree of cleaning by the pilot pressure in the compressed air line and / or by the time the pressurized air surge adjustably g, so that there is always a sufficient dust protection film remains on the filter bags.
  • the pre-pressure in the compressed air line can thus be controlled in a simple manner, for example, according to a predetermined program.
  • the time according to the degree of cleaning of the filter cloth is set with a relatively low pre-pressure in the compressed air line. It can surprisingly always achieve a sufficient dust protection film on the filter bags, so that damage to the bags, e.g. B. by tar approaches when coke pressing Hungarian fires can be avoided. It has proven to be advantageous according to the invention that the admission pressure in the compressed air line is at most 7 barg, preferably 4 barg, and the time of air application to the individual bag filter rows is between 0.1 and 1 second, preferably 0.2 seconds. This very low pressure and the short time are sufficient to remove a defined amount of dust from the walls of the bag filter.
  • the invention also proposes that the degree of cleaning of the bag filter be regulated as a function of the pressure drop drop achieved and measured by the cleaning.
  • the pressure loss at the bag filters can be measured and registered relatively easily in front of and behind the bag filter, so that a measured pressure drop drop can also be recorded and used as a measure of the degree of cleaning.
  • the pressure loss of the bag filter due to cleaning by 3 to 6 mbar, preferably 4 mbar.
  • the start and the end of the cleaning process of the bag filter system are also regulated as a function of adjustable setpoints for the pressure loss.
  • a cleaning process of the bag filter system can, if necessary, be initiated.
  • FIG. 1 the end of the coke oven on the coke side is indicated by (1). This is followed by the coke transfer valve (2), which is partially towered over by the hood of the hood wagon (3).
  • the coke extinguishing car (4) for receiving the glowing coke from the coke oven is shown under the hood.
  • the emission gases produced during the coke pushing out are drawn off via the hood of the hood wagon (3) into a stationary gas manifold (5) which runs along the coke oven battery and passed to the bag filter system (12) via a gas branch line (6).
  • a pre-separator (7) is connected upstream of the bag filter chambers (13), in which the dust-laden raw gas flow is diverted and any sparks and heavy dust particles are separated.
  • a fresh air flap in front of the bag filter prevents the permissible operating temperature of the filter bags from being exceeded.
  • the raw gas stream is on the raw gas channel (8) on z. B. distributed two filter blocks, each consisting of their individual filter chambers (13).
  • each filter chamber (13) there are several rows of bag filters, consisting of approx. 8 to 12 individual filter bags (30).
  • a compressed air line with compressed air supply (31) is arranged in the longitudinal direction above each bag filter row.
  • An injector nozzle (32) is located in the middle above each filter hose (30).
  • the filter bags (30) are flowed through with dust-laden gases from the outside in, the dust settling on the outside of the filter bags. When a blast of compressed air is initiated The dust hanging outside is loosened inside the filter bags and can fall down.
  • Each row of hoses is cleaned individually by a short burst of compressed air.
  • the filter cleaning runs through the entire filter in a predetermined cycle time.
  • the times are adjustable and can be adapted to the operating conditions.
  • the blast of compressed air during cleaning is set so that there is always sufficient dust on the filter bags to prevent the sticking of tar components on the bag material.
  • the upstream pressure in the air pressure line is increased to approx. 6 bar g, the pulse time to approx. 0.4 seconds and the suction volume to approx. 120,000 m 3 / h.
  • the so-called precoating ie the application of a protective layer to the filter bags after cleaning or before a new suction, can be completely dispensed with.
