Definitions
- the invention relates to a method and a device for cleaning contaminated or slagged containers.
- it relates to a process and a device for the so-called on-line blast cleaning of slagged Combustion devices according to the preamble of the independent claims.
- Heating surfaces z. B. from waste incineration plants or coal boilers are subject to general heavy soiling. These contaminants are inorganic Compositions and typically arise from the deposition of ash particles on the wall. Coverings in the range of high flue gas temperatures are mostly very hard as they either melt or melt on the wall remain or of deeper melting or condensing substances with them Solidification on the colder boiler wall. Such toppings are difficult and inadequate to remove by known cleaning methods. This causes the boiler to periodically shut down, cool, and manually or must be cleaned with sandblasting. Because such boilers are usually pretty large dimensions, it is often necessary to set up a scaffold in the furnace.
- Conventional cleaning methods are, for example, tapping the kettle and using it of steam jets, water jet blowers / sootblowers and bullet rain.
- a cleaning method is known in which the cooled and also in operation located hot boilers by inserting and igniting explosive devices is cleaned.
- a cooled explosive device by means of a cooled lance in the vicinity of the contaminated Brought heating surface where the explosive charge is ignited.
- the heating surface caking are caused by the force of the detonation, as well as by the the wall vibrations generated by the shock waves are blasted off.
- the cleaning time can use this method compared to traditional cleaning methods be significantly shortened.
- the cleaning can be carried out with the necessary safety precautions, on-line, i.e. during the operation of the incinerator or still in the hot state of the container. It is possible to use a boiler in this way Clean within hours, using a conventional cleaning method for days to be needed.
- the object of the invention is to provide a method and an apparatus for cleaning to create contaminated or slagged incinerators or containers, at which the system does not have to be shut down during cleaning, the System is in a clean state again in a short time and in particular the hazard of personnel and system parts minimized during the cleaning process becomes.
- the cleaning process disclosed here is based on gaseous, liquid and / or powdered or powdered substances or components, the individual or are preferably explosive only as a mixture, in the vicinity of an object to be cleaned to bring the at least partially gaseous explosive To explode mixture.
- the materials should be kept and handled separately to avoid the risk of an early explosion.
- This is possible with the cleaning method according to the invention, since the Cleaning required explosive substance or the explosive mixture at the point or can be made near the location of a container where he or it should be used. This increases the safety of personnel and objects.
- the cleaning device according to the invention during an insertion and Positioning process of the device still no explosive substances or components available and therefore not exposed to the heat.
- the cleaning method according to the invention is particularly suitable for incineration plants with sticky fly ash that tends to cake especially by burning coal, garbage, sewage sludge or soad waste. This is especially true in the area of steam generators of incineration plants.
- the cleaning process can also be used to remove dirt use in other systems with hard dirt deposits, e.g. in flue gas cleaning plants, Paper mills, silcs, in the cement industry etc.
- the blast cleaning can occur during the operation of a system, i.e. on-line, or at still hot containers and very precisely and precisely dosed. Thereby outage costs are reduced and no system parts or container sections are unnecessarily burdened. Also the dangers for the plant personnel minimized. This is particularly due to the extremely short dwell time of the at least partially gaseous explosive component or mixture in the hot Surroundings.
- the cleaning method according to the invention is a fuel, liquid or gaseous, e.g. B. acetylene, ethylene, methane, Ethane, propane, gasoline, oil etc., and an oxidizing agent, e.g. B. oxygen in the Brought close to a surface to be cleaned.
- a fuel, liquid or gaseous e.g. B. acetylene, ethylene, methane, Ethane, propane, gasoline, oil etc.
- an oxidizing agent e.g. B. oxygen in the Brought close to a surface to be cleaned.
- the strength of the explosion required for cleaning and thus the amount of used materials depends on the type of pollution and after Size and type of dirty container. Dosage and strength of the explosion can and are chosen so that no damage to installations occurs.
- the amount of mixed gas required for effective cleaning is of acetylene and oxygen between 5 and 30 liters per explosion.
- the optimal mixing ratio of the gases can be determined from the stoichiometry of the gases calculate and is 1: 3 for acetylene and oxygen. With an explosive gas mixture The ratio of oxygen and ethane is 3.5: 1 with an example total gas volume of approx. 100 liters.
- the possibility of optimal dosage of the components used on the one hand reduces the cleaning costs, on the other hand, the risk of danger and damage to the system and people.
- a tube-like device e.g. a lance
- a tube is in a plant or inserted a container and brought it close to the place to be cleaned.
- the or the components are introduced into the system or the container.
- the container to be cleaned and e.g. the flowing flue gas be hot up to 1000 ° C.
- the materials used for cleaning e.g. Gases and fuels
- the tube is thermal isolated and / or chilled. This can be done through a pipe made of thermally insulating materials or by cooling attached to or guided through the pipe happen.
- the cooling is preferably for a pipe and / or for cleaning
- the materials used are designed in such a way that they can be Coolant from the outside into the cleaning device or to the components or to the explosive gas mixture.
- a pipe or lance would have to be only be provided with connections for the gaseous components, for example and could be made correspondingly simpler.
- Such a cleaning device is also not due to the presence of water connections in the Depends on the proximity of the object to be cleaned. If a coolant such as For example, water is used as insulation material for the lance, so there are connections to be attached to the lance. Any hoses could, if desired, be removed before cleaning the lance.
- Cooling of the lance in the positioned state by means of coolant flow desired this is preferably done by passing a coolant through the lance so that it flows directly into the hot container.
- a cleaning device but can also be designed so that a coolant in the device again flowing back.
- the explosive, at least partially gaseous mixture preferably produced only at the point where the explosion is to take place. This is done, for example, by mixing one flammable gas and an oxidizing agent in a thin-walled container in the container to be cleaned itself but it is also possible to have the individual components in one part of a supply line, e.g. the lance inside. This will make the thorough Mixing of individual components shortly before the point to be cleaned began. It is also possible to take the necessary safety precautions directly explosive gas or gas mixture in a thin-walled container, which is located in a system or a container.
- the dosing of gases or gas mixtures, u. U. also of liquid materials, is preferably carried out via a pressure vessel into which exactly dosed beforehand Quantities of gas or liquid can be introduced, e.g. through controlled Filling from standard gas bottles.
- Quantities of gas or liquid can be introduced, e.g. through controlled Filling from standard gas bottles.

- the gases or liquids under pressure the length of time of the components used in the hot environment is extremely high be kept short.
- a suitable thin-walled container To dilute gases, gas mixtures, powder or powder or liquid materials, e.g. B. to avoid by ambient air or flue gas, the materials are as close as possible to or near the place to be cleaned held by a suitable thin-walled container. This is Particularly advantageous if an explosive mixture is only close to the cleaning surface is to be produced, for example by a separate guidance of individual Gases or fuels in a pipe-like device or lance.
- Such a container serves, among other things, to avoid the dilution of the gases, especially before they are completely mixed and, if necessary, for their mixing Cooling.
- suitable thin-walled containers are stretchable thin-walled balloon-like containers, or flexible, compliant thin-walled containers such as for example sack-like envelopes or pouches.
- a thin-walled container is preferred at one end of a pipe, e.g. attached to the head of the lance and is inflated by the gases themselves.
- the thin-walled containers preferably have a larger volume than that total volume of the components brought into it. On the one hand, this prevents premature destruction of the thin-walled container by bursting, e.g. of elastic balloon-like containers.

- Passive cooling for one explosive mixture and one Lance is independent of active coolant supplied from outside during the Cleaning process itself, i.e. in the inserted condition of the lance.
- a passive one Lance cooling is preferably done by attaching suitable materials around the gas and / or liquid pipe or by producing the Pipe or supply lines made of suitable materials. These are, for example insulating, essentially heat-resistant and / or coolant-absorbing Materials or suitable material arrangements. Examples of the latter are absorbent Materials such as paper, wadding, or fabric that are in water or before use other coolant. To protect against injury to a cooling Layer, outer protective layers can be applied.
- cooling methods and protective devices can also be combined, omitted or supplemented.
- the ignition of the explosive gas mixture or liquid / gas mixture takes place from the state of the Technology known means. This is preferably done by electrically triggered Spark ignition, by auxiliary flames or by pyrotechnic ignition with the help of appropriately attached ignition devices and ignition devices.
