  • the invention relates to a system for handling and processing of solid combustion residues from a furnace.
  • a wet-type decanter is provided as part of the known measures, in which the ash, whose temperature may be about 500 to 600 ° C, is quenched with water.
  • the wet scrubber has an elongate collecting container which contains a water bath and is arranged below the opening of the usually several ash outlet funnels of the furnace. It contains a conveyor with circulating chains, which receive the combustion residues discharged from the ash outflow funnels and transport them to the discharge, which is rising.
  • the invention has the object to provide a maintenance-friendly device for transporting away and handling the combustion residues.
  • an exchange of arranged under the ash outlet funnels parts of the system should be easily possible.
  • the invention and solution of this problem is a system for handling and processing of solid combustion residues from a furnace according to claim 1.
  • the system has at least one collecting container, which is arranged on the underside of an ash outlet funnel of the furnace and contains a water bath.
  • a crusher for crushing the emerging from the ash outlet funnel combustion residues is arranged in the collecting container above the water bath.
  • the breaker room is charged with water.
  • a device for hydraulic delivery is connected to the collecting container, which feeds a water and combustion residues existing suspension from the collecting container of a separating device for the separation of solids. If the firing plant has several ash outlet funnels, each ash outlet funnel is assigned a separate collecting tank with crusher and a device for the hydraulic conveyance of the suspension consisting of combustion residues and water.
  • the lines of the hydraulic conveyors are preferably formed wholly or partly as flexible hose lines.
  • the suspension streams withdrawn from the plurality of collecting containers can be fed to a common separating device for the separation of solids.
  • the effluent from the separating device, essentially solids-free liquid is returned to the collecting container and divided thereon.
  • a slide is preferably arranged between the ash outlet funnel and the collecting container.
  • the bin By closing the gate, the bin can be removed for maintenance or repair work and replaced with a suitable replacement unit without interrupting the operation of the firing system.
  • the collecting container is movably arranged on rails and for maintenance between a working area below the associated ash outlet funnel and a second position spaced from the work area.
  • the crusher arranged in a container section of the collecting container above the water bath comminutes the slag leaving the ash outlet funnel so far that the solid parts can be hydraulically conveyed.
  • the inlet area of the crusher is acted upon by means of an all-round nozzle line with water.
  • the crusher is designed so that the solids after comminution have a particle size between 0 and 50 mm.
  • the crusher is a roll crusher. Other versions should not be excluded.
  • the ash outlet funnel can be connected in a gastight manner to the collecting container.
  • a funnel is arranged below the crusher, which dips into the water bath.
  • the ash outlet tank is expediently equipped with a pressure compensation system.
  • a pressure compensation pipe is installed above the water level in the area of the cover of the collecting container so that pressure equalization is ensured in the event of any deflagration.
  • the suspension pumped out of the collecting container is fed to a separating device for the separation of solids.
  • the separating device preferably has a vibrating screen.
  • the filtered liquid is traceable after separation of finely divided solids in the collecting container.
  • the screen residue is a dewatered product, the residual moisture content is typically about 30% or less, can be stored in a silo and transportable without complex special vehicles.
  • the product is for example in the construction industry, especially as an additive to building materials commercially available.
  • the vibrating screen has two juxtaposed or stacked sieve trays, one of the sieve trays being equipped with a coarse sieve and the other sieve tray with a fine sieve.
  • the passage of the coarse and fine sieve is fed by means of a pump to a hydrocyclone.
  • the sieve residues of the coarse sieve and the fine sieve can be used commercially as dewatered ash products of different grain sizes.
  • the liquid flow from the upper run of the hydrocyclone is essentially low in solids and is returned to the collecting containers.
  • the solids-rich suspension stream from the lower reaches of the hydrocyclone can be fed to the vibrating screen. There is a largely closed liquid circuit, so that essentially only liquid losses associated with the withdrawal of the dewatered sieve residues must be compensated.
  • the system shown in the figures has a plurality of independent collection container 1, which are arranged below a furnace and each associated with an ash outlet funnel 2 of the furnace.
  • Each of these collecting container 1 contains a water bath 3 and has a crusher 4 for crushing emerging from the ash outlet funnel 2 Combustion residues, which is arranged in a container portion above the water bath 3.
  • the crusher chamber is charged with water, which is preferably supplied by means of a nozzle line extending all around.
  • To the collecting container 1 means 5 are connected to the hydraulic conveying, which feed a consisting of water and combustion residues suspension from the collecting containers 1 a separating 6 for the separation of solids. After separation of the solids, the liquid is returned to the collection container 1.
  • the ash outlet funnel 2 and the collecting container 1 are connected in a gastight manner.
  • a funnel 14 is arranged, which dips into the water bath 3.
  • a pressure equalization pipe 15 is connected, which ensures a pressure equalization to the environment in case of possible deflagration.
  • a slide 7 is arranged in each case. If maintenance work on the collecting containers 1 or the associated units are necessary, the slide 7 is closed. Thereafter, the collecting container 1 can be separated from the ash outlet funnel 2, without the furnace system must be shut down.
  • the receptacles 1 are movably mounted on rails 8 and are movable for maintenance between a work area I below the associated ash discharge hopper and a second position II spaced from the work area. A previously provided collecting container 1 'can then be moved to the working position I and connected to the ash outlet funnel 2.
  • the crusher 4 is z. B. formed as a roll crusher and comminuted emerging from the associated ash outlet funnel 2 slag so far that the solids in the water bath as a suspension can be hydraulically conveyed.
  • the crusher 4 is designed so that the solids have a particle size in the range between 0 and 50 mm.
  • the crusher 4 is arranged in the embodiment in a container section above the water bath 3 and the crusher chamber is acted upon by means of a ring line with water.
  • the collecting container 1 contains in the embodiment inside a Grobsieb 9, with the foreign body, for. As iron parts are retained.
  • the screen surface of the coarse screen 9 is arranged obliquely, so that any retained foreign matter at a lower end collect and can be easily removed from time to time.
  • the coarse filter 9 is designed as a double screen and has two superimposed screen surfaces. This arrangement also enables effective deposition of metal wires.
  • the separating device 6 consists of a vibrating screen, which in the exemplary embodiment has two adjacent or stacked sieve trays 10, 10 '.
  • One of the sieve trays is equipped with a coarse sieve 10 and the other sieve tray with a fine sieve 10 '.
  • Sieve residues are largely dewatered ash products in different grain fractions, which can be used commercially, for example, in construction as aggregates for building materials.
  • the sieve passages of the coarse sieve 10 and the fine sieve 10 ' are fed by means of a pump to a hydrocyclone 11, which divides the liquid flow into a substantially solids-free liquid stream 12 at the cyclone upper run and into a suspension stream 13 withdrawn at the lower end of the hydrocyclone.
  • the suspension stream 13 is returned to the vibrating screen.
  • the substantially solids-free liquid 12, which is obtained at the cyclone overflow is returned to the collecting container 1.
