Definitions

  • the present invention relates to a method of recycling solid domestic wastes.
  • the given problem is very pressing today and requires new ways to settle it.
  • the most widespread method for handling this problem is waste incineration.
  • the weak point of the given method is that there are certain demands to the composition of the starting raw materials, as well as a strict technological dependence on the processes which happen in the neighbouring furnaces.
  • the present invention is aimed at the development of a highly effective, and at the same time very economical way of recycling solid domestic wastes. It does not require expensive equipment and reactants.
  • the method if fulfilled, practically excludes completely the formation of toxic products received at burning, dioxins in particular.
  • the task undertaken is coped with because the solid domestic wastes preliminary go through crushing and drying unless moisture does not exceed 50%.
  • Heat treatment is carried out in the black liquor recovery furnace at temperature 1100-1700 C, in the strong alkali medium.
  • the time of staying the products of burning in the flame is not less than 2 seconds.
  • the burning at this takes place on the cushion of hearth furnace, on condition that waste inlet is one meter higher than fuel inlet, not less.
  • the optimal way is to use organic or bio-organic fuel received from abundant activated sludge at the concentration of 60-75% absolutely dry substance, and to provide heat treatment at temperature 1000-1500 C.
  • the method proposed affords to recycle solid domestic wastes (SDW) effectively. It practically affords to exclude completely the formation of dioxins, makes the process cheaper at the account of using the well-known equipment which brings to a considerable reduction of costs.
  • the black liquor recovery furnace (CPK) mentioned above is used in pulp industry for burning black lye (U.Nepenin "Production of sulphate pulp", v.2, Timber industry, 1990).
  • Picture 1 shows the flow chart of the unit for incinerating SDW by the method proposed herein.
  • the unit consists of magnetic separator (1,5), container (2,6), crusher (3), conveyor (4), drum for drying (7), transportation device (8, 12), pipe reactor (9), cyclone (19), bunker (11), boiler (13), tank for melting (14), clarifier (15), electric filter (16), scrubber for smoky gases (17).
  • the wastes are fed by the transportation device (12) through atomiser to the hearth of the boiler (13).
  • the mineral part melts and flows to the tank (14) in the form of mineral salts.
  • the suspension is pumped from the tank to the clarifier (15), where the unsolved part forms a sediment and through the hydraulic ash filter is moved away to a dump.
  • the soda solution from the clarifier is fed to the scrubber (17), and then from the scrubber the water with ash caught returns to the clarifier.
  • the smoky gases purified are released to the atmosphere. In this case, chemical destruction and high temperature burning happen simultaneously in the one reactor.
  • the method is carried out in the way described above.
  • the temperature sustained is 1100-1500 C.
  • the duration of staying in the given temperature is 9 seconds.
  • the velocity of feeding wastes is 3 t per day.
  • the quantity of dioxins that can appear at this is _____.
  • the volume of gases released is 20000 Hm3/hour.
  • the discharge of dioxins measured in the smoky pipe after filtering, is 1 ⁇ /m3.
