Definitions

  • the invention relates to a smoldering drum for the smoldering of waste materials such as household waste, industrial waste, old tires, plastic waste, sewage sludge or the like, consisting of a drum, heating elements arranged in the interior for passing hot gases for the indirect heating of the smoldering material, a gas collecting chamber for introducing the hot Gases into the heating elements with a seal against the drum, a gas collection chamber for discharging the hot gases from the heating elements with a seal against the drum, an entry device for the carbonized material into the drum, a discharge device for the smoldered material from the drum, and a discharge for the carbonization gas, which is connected to a dust collector.
  • waste materials such as household waste, industrial waste, old tires, plastic waste, sewage sludge or the like
  • waste materials are carbonized in an indirectly heated drum at temperatures of about 300 to 800 ° C.
  • the carbonization gases and the solid carbonization residue are drawn off at the discharge end of the carbonization drum.
  • the carbonization gases are converted into mechanical gas cleaning, e.g. a cyclone separator, in which a large part of the dust carried by the carbonization gases is removed.
  • a smoldering drum which is equipped with hollow circulation blades.
  • the circulating blades extend in the longitudinal direction of the drum and open into a gas collection chamber on both ends. Hot gases are introduced into the circulation blades through the gas collection chamber at the discharge end of the drum and drawn off into the gas collection chamber at the end of the inlet.
  • the smoldering material is introduced through the gas collection chamber at the end of the feed.
  • the carbonized material is discharged and the carbonized gases are removed by means of a conveying device through the middle of the end wall of the drum and through the gas collection chamber at the discharge end of the drum.
  • the solid carbonization residue falls into the discharge and the carbonization gas is drawn off upwards and passed into a dust separator.
  • the object of the invention is to keep the dust content in the carbonization gas as low as possible after the mechanical cleaning.
  • the dust separator is arranged in the gas collecting chamber for introducing the hot gases and washed around by the hot gases, the discharge for the carbonization gas is guided through the wall of the gas collecting chamber into the dust separator, and the discharge line for the dusted part Carbonization gas and the discharge for the separated solids from the dust separator are led through the wall of the gas collection chamber.
  • the mechanical dust separator is preferably designed as a cyclone.
  • the hot gases are preferably generated in a combustion chamber which is connected directly to the gas collection chamber. The hot gases flow around the dust separator and prevent condensation in the dust separator.
  • the discharge device for the solid smoldering residue is sealed against the ingress of air, e.g. through a double lock or gastight cellular wheel lock.
  • the front ends of the drum are sealed against the escape of carbonization gases into the gas collection chamber or the penetration of gases from the gas collection chambers into the drum.
  • an end wall is used, in which the hollow heating elements and the insertion and discharge device are embedded gas-tight.
  • a preferred embodiment is that the discharge device for the smoldered material is arranged in front of the gas collection chamber for introducing the hot gases into the heating elements, the discharge device consists of a stationary housing with seals against the drum, the drum in the housing is equipped with openings in the jacket , the front of the drum in the. Gas collection chamber is closed against the escape of carbonization gases, the discharge for the carbonization gas is arranged in the housing and is connected to the dust separator by the wall of the gas collection chamber.
  • the openings in the casing of the drum are distributed over the circumference of the drum. Their size will be according to the size of the parts of the smoldering residue selected. For security reasons, some openings can also be made larger.
  • the shape of the openings is preferably slit-shaped.
  • This configuration ensures that there is no build-up of smoldering residue in the drum before the end of the discharge, thereby avoiding a grinding effect on the smoldering residue and significantly reducing the amount of dust that accumulates. Furthermore, a separation from the carbonization gas and carbonization residue already occurs in the drum, as a result of which the dust content in the carbonization gas drawn off is reduced. The carbonization gas emerging from the dust separator therefore has a lower residual dust content.
  • a preferred embodiment consists in that a throttle valve is arranged in the trigger for the carbonization gas, which is controlled as a function of the pressure upstream of the throttle valve.
  • Heating elements 2 are arranged in the interior of the drum 1.
  • a stationary gas collection chamber 3 is arranged, which is sealed against the drum 1 by a seal 4.
  • the hot gases emerge from the gas collecting chamber 3 into the tubes of the heating element elements z.
  • the stationary gas collection chamber 5 for discharging the hot gases from the heating elements 2 is arranged, which is sealed by a seal 6 against the drum 1.
  • a feed screw is arranged gas-tight against the gas collection chamber 5 and the end wall of the drum 1 as the entry device 7.
  • the trigger 9 for the smoldering gas is arranged in the upper part.
  • the line of the trigger 9 is guided through the wall of the gas collection chamber 3 and into the dust separator 10.
  • the discharge line 11 for the dedusted carbonization gas and the discharge 12 for the separated solids are led out of the dust separator 10 through the wall of the gas collection chamber 3.
  • the discharge device 8 consists of a stationary housing 13, which is arranged in front of the gas collecting duct 3 and is sealed against the drum 1 with seals 14, 14a.
  • the drum 1 is provided with openings 15 within the housing 13.
  • the heating elements 2 are guided gas-tight through the end wall of the drum 1.
  • the discharge device 8 consists of a tube with spiral flat iron, which is passed gas-tight through the end wall of the drum 1 and the gas collection chamber 3.
  • the smoldering residue falls into the discharge 16 to which the trigger 9 for the smoldering gas is connected at the top.
  • the combustion chamber 17 for generating the hot gases is connected to the gas collection chamber 3.
  • a throttle valve 18 is arranged in the trigger 9 and keeps the pressure in the gas separator 10 constant.
  • the control takes place by measuring the pressure upstream of the throttle valve 18, which is controlled in accordance with the measured pressure via a control 19.
  • the discharge of the solid deposited in the dust separator 10 material takes place via a cellular wheel sluice 20.
  • the smear residue is discharged from the discharge device 8 through the gas-tight flaps 22 and 22a. When opening and closing the flap 22 is protected by the slide 21, which stops the flow of the solid during this period. Air infiltration through the flaps prevents an inert gas which flows through the inlet 23.
  • the advantages of the invention are that there is certainly no condensation of condensable constituents in the dust separator and also in the discharge of the carbonization gas from the dust separator and the residual dust content in the carbonization gas after the dust separator is reduced.
