Definitions

  • the invention relates to methods and devices for removing odorous substances in gases or vapors which are used in the processing of organic substances, e.g. Food or luxury goods, created in a manufacturing facility.
  • Gases or vapors are produced in industrial food and luxury food processing, which contain strongly odor-active substances. These substances are usually organic compounds such as alcohols, aldehydes, ketones, esters, etc.
  • vapors that occur during the preparation of the mash and wort boiling in a brewery are gases and vapors laden with odor, which are used in the processing processes e.g. in fish and meat processing plants, smokers, roasters, deep-frying plants, canteen kitchens, fat melts and malting plants, but also outside of the food and luxury food industry e.g. in cellulose and paper factories, rendering plants and crematoriums.
  • Filters, scrubbers or post-combustion systems are known for removing or removing odorous substances from gases or vapors.
  • the invention has for its object to provide a method of the type mentioned, with which odorants can be removed from vapors in an extremely simple and extremely effective manner. Devices with which such a method can be carried out are also to be found.
  • this object is achieved in that the gases or vapors laden with odor are fed to a firing system of the manufacturing system and are heated there to at least 400 ° C.
  • the process according to the invention is based on the knowledge that the organic odorous substances, such as those contained in the brewhouse vapors, are decomposed at higher temperatures, water vapor and carbon dioxide predominantly being produced. When heated above the combustion temperature, the odorants also largely oxidize to water vapor and carbon dioxide in the presence of atmospheric oxygen. The resulting gases can then be discharged through the chimney with the flue gases of the combustion system, without any odor nuisance to the environment.
  • the odor-laden gases or vapors are not fed to a special post-combustion system, but rather to the combustion system which is already present in the manufacturing system for supplying energy to the machining process.
  • the use of the method according to the invention can even lead to an energy gain if the warm or hot gases or vapors replace part of the combustion air that would otherwise be supplied to the combustion system at ambient temperature becomes.
  • the vapors produced during the cooking of mash and wort in a brewery plant are fed to the firing plant of the brewery and heated there. Since the brewhouse is the main heat consumer in breweries, and this brewhouse is heated by the firing system, it can be guaranteed that the firing system is in operation during brewing. Appropriate control can ensure that the odor-active substances escape from the mash or Wort pan the combustion system is not switched off, but the vapors are heated. By heating the vapors in the brewery's firing system, it is extremely easy to completely remove the odorous substances.
  • the device according to the invention for carrying out the method in a brewery plant with a container 1 having a steam outlet 12 for boiling mash and / or wort and with a firing plant 13 which supplies the energy for the processes of mash preparation and wort boiling is characterized in that Steam extraction is connected via a gas duct 5 to the furnace.
  • the invention thus provides that a pipeline 5 begins at the steam outlet 2 and 12 provided anyway on the wort or mashing pan, in which a pan vapor condenser 3 can also be included, which leads to the firing system.
  • the steam is thus directed from the steam exhaust to the furnace.
  • a corresponding control flap 4 can be provided in the fume hood, which connects the fume hood in one position to the surroundings and in another position to the pipeline to the furnace.
  • the odor-laden gases or vapors can be fed to the combustion chamber or flue gas tract of the furnace at any point, as long as it is ensured that the odor-laden gases or vapors reach a temperature of at least 400 ° C after mixing with the combustion or flue gas of the furnace ensure the thermal decomposition of the odorants.
  • the rear turning chamber of the flue gases between the flame tube and the first flue pipe is suitable, where a nozzle 15 for introducing the odor-laden gases or vapors can be attached with very little effort even in existing systems and where in the flue gas Temperatures in the range of 700 - 900 ° C prevail.
  • a structurally very inexpensive way of supplying the odor-laden gases or vapors to the combustion system is to mix them with the combustion air.
  • the firing system is a gas or oil burner system known per se
  • the gases or vapors are fed together with the combustion air to the mixing chamber 6 of the burner and then burned in the combustion chamber.
  • a simple connection channel between the steam exhaust and the burner is sufficient, a mixture of combustion air with the gases or vapors being generated in front of the burner inlet, which is then burned with the fuel in the burner chamber.
  • the energy of the furnace can of course be given to the mash and wort pans for direct heating or indirectly using hot water or steam.
  • a container 1 denotes a container, for example a wort kettle in a brewery system.
  • wort or mash is cooked with the help of the heating device 11 in a known manner.
  • steam is generated which contains strongly odor-active substances.
  • a steam exhaust 2 is provided on the lid of the container 1, through which the steam emerges from the container at the top.
  • the steam can rise further above a ladle vapor condenser 3 indicated by a broken line.
  • a swiveling flap 4 is accommodated in the steam extraction line 12, which in the position shown redirects the steam with the odorous substances into the pipeline 5. When the flap is oriented in the vertical direction, the steam escapes into the free atmosphere in the direction of the arrow P u .
  • the steam as mentioned, is introduced into the pipeline 5 and is guided to the firing system, designated overall by 13.
  • the furnace 13 is indicated in the figure as a gas or oil burner system, which has a mixing chamber 6 and the actual combustion chamber 7.
  • Steam P D containing odorous substances and the combustion air P L mixed.
  • the fuel P B is burned in the combustion chamber 7 in a flame 8.
  • the combustion temperature of the flame 8 is usually above 1000 ° C. Due to the temperature of the flame 8, the odor-active substances consisting of organic compounds such as alcohols, aldehydes, ketones and esters decompose and mainly decompose into carbon dioxide and water vapor.
  • the exhaust gases can then escape through the exhaust stack 9 without odor-active substances being contained therein.
  • the energy obtained by the combustion in the combustion chamber 7 is fed via the line 10 to the heating device 11 and is used to heat and boil the medium in the container 1. This not only eliminates the odor-active substances from the gas or steam of the heated substance and thus to avoid annoying the environment due to unpleasant smells, but also to partially recover the heat contained in the steam.
  • this principle of eliminating odorous substances can be used not only in brewery brewing plants, as shown, but also in fish and meat processing plants, smokers, roasters, deep-frying plants, canteen kitchens, fat melts and malting plants as well as in cellulose and paper factories , Carcasses, crematoriums and the like.
