DE2112754C3 - Device for cleaning flue gases and the like - Google Patents

Description

wiinschi be repeated. In the case shown there is only one repetition; the flue gases flow through the curved channel 4 between Container basin and this design adapted ceiling 5 in the second chamber part in which the particles still remaining after the first cleaning stage are thrown into the second melt bath 6. That way from the fixed parts Freed, cleaned and sterile gases are fed through a line 7 in the direction of the light arrow to a heat exchanger, for example for heat recovery, or are discharged into the outside air. The device causes a very effective cleaning of the gas from soot, ash and the like the particular advantage is that the molten baths 3 and 6 can be cast in molds, which can be used industrially or buried without any problems.

The molten baths 3 and 6 are kept continuously in the liquid state with the aid of adequate insulation. In addition to the hot flue gases, an inductive or high-frequency heater 8, 9 can be provided to maintain heat. The melt pools 10 and 11 can be tilted so that the melt can be emptied from time to time and poured into molds. In the case of stationary basins, the melt can be withdrawn in any other known manner. After cooling, solids are removed from the molds by, for example, plates, rods, bricks or similar parts. If these solids are buried in the earth like waste, they are only water-soluble to a very limited extent and do not endanger the groundwater. Cast from the melt

In addition, blocks can be used as raw material for numerous branches of industry. The construction industry in particular requires many materials with exactly the properties of the parts cast from the ash melt. As an example, only different

Lent building boards and panels mentioned.

The device is very simple in its construction and can be manufactured and operated accordingly inexpensively. The essential element is the ash bath, into which the melted particles of the flue gases are thrown by the curved flow path.

In a further development of the example explained air can be supplied to the device, which removes the combustible particles of the flue gases, e.g. B. that Carbon monoxide, burns.

Claims (1)

2Ü27Ö4 4 ι ² zebades is affected by the fact that the Patent claim- surface of the molten bath floating Scblakra a ρ kenschicht the direct entry of the ash device for cleaning flue gas particles in the surface of the molten metal bath and the like with a molten bath guided chamber into which 5 is prevented the flue gases are introduced from above. The object of the invention is to en » and they go through the device for cleaning flue gases in an approximately horizontal direction cross, characterized in that create the simple and cheap way to smoke the Kanuner (2) through at least one tub of gases before they are released to the outside air bz-v. Feed shaped container basin (10, II) under i ° energy recovery in heat recovery units one of the tub shape adapted joint fully cleans and also the urawelt-friendly loading Cover (S) is formed and allows the separated solid particles to be separated This is achieved in that the chamber, 15 through which the flue gases are passed, by at least one tub-shaped container basin under one of the tubs The invention relates to a device for cleaning a common ceiling. In this way the supply of flue gases and the like with a melting bath creates a gas flow path through the device, the chamber, into which the flue gases enter from above, transversely to the feed direction of the gas flow in and which it is curved in an approximately horizontal, vertical plane, whereby it is achieved that the solid flue gas particles, which are very high in the chamber due to the tightened legal provisions, are aimed at that at the Elimination solid into a molten state, on household and industrial waste as far as possible due to the centrifugal force triggered by the rapid flow of gas, groundwater or soil contamination, and from this straight in to keep the air clean the incineration of the waste occurring in the tub-shaped container basin collecting the smoke-melt pool of fly ash. Before being released into the outside air, the pre-gas is subjected to cleaning for all types of flue gas, in the course of which soot and ash can be fully used. The ashes and soot as well as particles removed from the smoke stream are to be removed from other non-combustible components of the smoke gases. In addition, in connection with the pro-formed melt can be poured into pieces of the desired problem of keeping the environment free from harmful forms, which no longer have any impact on waste disposal pro-pollution and also take account of problems, because their digging into groundwater pollution and soil contamination the soil Take the risk of groundwater pollution when it comes to excluding those from smoking with certainty and removing the dirt particles that have also been separated out in gases. even as a raw material for reduced industry - it has been shown, for example, that unbound ash buried in the branches, for example the construction industry, usable soil is below 40. By arranging several trough-shaped tank basins in a row, the process that causes groundwater pollution can be repeated until the desired level, which is why the waste gas is clean in this direction. Must be done with each pass. In the German patent specification 969 876, a 45 solid particles device for separating fly ash is thrown from the gas stream into the molten bath until practically no particles in the Abhochtempcrierten flue gases are described in which there are more in the gas stream. Since the gas flow can flow freely over the molten bath, a metal can flow away from the container-like lower part of a chamber, a tall molten bath is accommodated into which the device with a very large capacity with always baffles protrudes somewhat from above. Purpose of this under the 50 constant excellent cleaning effect.
Surface of the molten metal bath immersed The invention is explained in more detail using one of the retaining walls in the drawing to press the exemplary embodiment fire gases introduced into the chamber into the molten metal bath. The single figure shows a vertical section to resolve gas flows. The ash parts carried along - 55 a schematic diagram of the device,
Chen should in this way come into contact with the liquid metal in the direction of the dotted arrow from above and form a flowing flue gas entering the channel 1 will compress a slag layer, which is fed to the metal chamber 2, in which the solid parts the smoke bath floats and can be diverted. gases because of the strong radiation of a molten metal bath, 60 of which has to be regenerated and replenished in a molten metal bath, 60 of which has to be regenerated and refilled. Due to the considerable density of the device's effectiveness due to the high temperature, which is expensive due to the known device, one particles separate quickly from the one in the arch, because the throughput is due to the gas flow flowing towards it and get straight through the metal melt 6s into which is relatively small in a tub-shaped container bath per unit of time and basin 10 collected melt bath 3, from which they to the other, because the cleaning effect of the adhesive surface for the quickly absorbed by its surface tension Ash particles are melted. This process can be carried out as often as
