Definitions

  • the proposed system is a full-scale automated system for the destruction of air pollutants originating from wastewater treatment plants.
  • the system consists of one or more ventilators, depending on the application system (with or no recycling), a gas collector with convex surface-usually dome, tubes, compressor, sensors, specially modified incinerator, chimney, flow rate of LPG or another fuel.
  • the biomass consumes about 1 kg O 2 /m 3 waste. As a result it requires a sufficient quantity of air for biomass growth and compound degaradion.
  • the air (oxygen) enters the tank, partly through the bottom, via a compressor with a system of thin tubes and partly from the surface due to armospheric oxygen. Brush aerators will be used in order to transfer atmospheric oxygen to the waste.
  • a ventilator which absorbs the mal-odorous gases and routes them to the incinerator (with a pressure sensor in the dome) through tubes with two one-direction safety valves.
  • the mixture of air and mal-odorous gases is originated from the waste degradation, the compressor air bubbles and the inlet fresh air from vent-holes (one direction from outlet to inlet) on the base of dome external perimeter.
  • the gas collector with convex surface is fitted air-tightly on the wastewater treatment tanks, in order to avoid gas leakage. It is manufactured by a light but resistant material.
  • the automated system of polluted gases purification includes the following units: 1 ) A gas collector with convex surface, by light and resistant material, which is suited tightly on the wastewater treatment tanks
  • Tubes which route the exhaust gases from the exhauster outlet to the specially modified incinerator, founded with one direction valves, sensors etc, as well as a tube from the dome outlet to the compressor inlet if recycling is implemented.
  • a specially modified incinerator LPG fuel enters the flame of the incinerator in order to achieve the combustion of the mal-odorous gases.
  • the gases have passed through a heat exchanger (Labyrinth) for preheating, in order to achieve reduction of required combustion gas, LPG or natural gas or coal oil.
  • the incinerator and boiler consist of: a)"Labyrinth" The mal-odorous gases pass in counter-flow direction and are preheated. They also maintain the outer surface of the incinerator at low temperature. b)"Turbulent mixer” It enhances the turbulence and, as a result, the gas mixing. In this way, more effective gas incineration is achieved. c)"Flame splitter” A non-aerodynamic cone that makes the flame flow in a turbulent way and operates as if tearing the flame in order to make it spread in a longer radial. d) "Catalyst" A catalyst could be optionally used to achieve better temperature conditions. This, however, would raise the cost of the project.
  • Heaters which are the necessary stabilizers of the relative humidity in the inner curved surface to prevent problems in the operation of the gas exhauster or the ventilator
  • the whole construction is to be equipped with sensors and fully automated.
  • the construction is very economical and necessary for the protection of the environment and the maintenance of the ecological balance, with the benefits from the production of the thermal energy.
  • FIG. 1 Collector Figure 2 Collector + Gas Exhauster Figure 3 Collector + Gas Exhauster + one-direction Valves Figure 4 Collector + Gas Exhauster + Ventilator + one-direction Valves + Compressor and the suitable tubing if recycling is implemented Figure 5 : Collector + Gas Exhauster + Ventilator + 95 one-direction Valves + Compressor and the suitable tubing if recycling is implemented + tubing from the dome outlet to the incinerator Figure 6 : Collector + Gas Exhauster + Ventilator + one-direction Valves + Compressor 100 and the suitable tubing if recycling is implemented + tubing from the dome outlet to the incinerator + Incinerator and Boiler Figure 7 : Collector + Gas Exhauster + Ventilator + one-direction Valves + Compressor 105 and the suitable tubing if recycling is implemented + tubing from the dome outlet to the incinerator + Incinerator and Boiler + Fuel tank + Chimney
  • the Figure 8 shows the incinerator and boiler parts: Figure 8.
  • A Labyr
  • composition of air pollutants from these wastewater treatments plants typically 120 include:
  • the dome (a convex surface which is fitted air-tightly on the wastewater treatment tanks) will be constructed out of iron sheet 6 mm, in order to avoid leakage due to the welding of the iron sheets.
  • the biomass consumes 1 kg O /m waste and about 670 'm air/day (28 m /h) are required. Based on this consideration, a dimensioning of the construction will be
  • the required quantity of air is the sum of 280m" Pa and the air of 150 compressor (m 3 /h) that is necessary for biomass oxygenation.
  • the air (oxygen) will be bubbled with a system of thin tubes at the bottom of the plant.
  • the dimensioning of the incinerator will be based on the gas-mixture velocity 155 (mal-odorous gases + LPG) from the turbulent mixer in order to avoid flame extinction.
  • a catalyst could be used to achieve conversion at lower temperatures.
  • the system will include portable analytical equipment for monitoring of all 160 the polluting gases and and the flow rate of the LPG can be regulated in order to achieve almost perfect combustion.

Abstract

L'invention concerne un système automatisé à grande échelle, destiné à la destruction de polluants aériens provenant de stations de traitement d'eaux usées, comprenant un collecteur de gaz à surface convexe, un extracteur électrique et automatique de gaz au sommet du collecteur, un ventilateur ou des vannes unidirectionnelles, à passage de l'extérieur vers l'intérieur du dôme collecteur de gaz et situées à la base de sa périphérie, et des conduits qui mènent le gaz à l'incinérateur spécialement modifié, dans lequel les émissions gazeuses sont brûlées à l'aide d'un gaz-combustible (habituellement du gaz naturel), avec production simultanée limitée d'énergie thermique.
