Definitions

  • the present invention relates to apparatus for flue gas puri ⁇ fication and heat recovery, wherein the flue gases from a heating boiler are directed to a heat exchanger, in which the flue gases yield their heat to a substance, such as air, flow ⁇ ing on the secondary side of the heat exchanger.
  • the flue gas purification and heat recovery apparatus according to the invention is charac ⁇ terized in that the outlet side for warm air in the heat ex ⁇ changer is connected to a regenerative air conditioning and heat recovery apparatus.
  • condensation takes place in the flue gases, whereupon the water vapor present in the flue gases will flow downwards, while impurities, heavy metals and sulfuric acid, will become bound to it.
  • the flue gases at the same time yield their heat to the air flowing on the secondary side, the air for its part heating up the batteries of the air conditioning and heat re ⁇ covery apparatus.
  • One embodiment of the invention is characterized in that the heat exchanger primary side, where the flue gases flow, and the heat exchanger secondary side, where the air flows, are connected to the heating boiler and to the air-conditioning and heat recovery apparatus in such a manner that the flows in the heat exchanger are parallel.
  • Another embodiment of the invention is characterized in that the diaphragm between the primary and secondary sides of the heat exchanger is elongate and in its cross section corrugated in such a manner that its surface area is maximal. Thus a very uniform and laminar flow is accomplished in the heat exchanger on both the primary side and the secondary side.
  • a third embodiment of the invention is characterized in that in the lower section of the heat exchanger there is a vessel into which the condensed liquid and the impurities flow and in which chemicals are used to neutralize the impurities which have dissolved in the condensed liquid.
  • this vessel is further connected, for example, directly to a drain or to a larger collection vessel, it need not be emptied periodically.
  • the required chemicals may also be provided by feeding them into the vessel according to need, for example, via a tube.
  • Figure 2 depicts a cross sectional plan view of the heat ex ⁇ changer.
  • the flue gases from a heating boiler 1 are directed to a heat ex ⁇ changer 2, in which the flue gases yield their heat to air flowing on the secondary side 3 of the heat exchanger.
  • the warm-air outlet side 5 of the heat exchanger 2 is connected to a regenerative air-conditioning and heat recovery apparatus 6.
  • the heat exchanger 2 primary side 7, where the flue gases flow, and the heat exchanger secondary side 3, where air flows, are connected to the heating boiler 1 and to the air- conditioning and heat recovery apparatus 6 in such a manner that the flows in the heat exchanger are parallel, i.e. in this case downward from above.
  • the diaphragm 8 between the primary and secondary sides of the heat exchanger is elongate and in its cross section corrugated so that its surface area is maximal.
  • a vessel 9 into which the condensed liquid and the impurities flow and in which chemicals are used to neutralize the impurities which have dissolved in the con ⁇ densed liquid.
  • the liquids neutralized in the vessel 9 are directed via a pipe 10 to the drain or to a separate collec ⁇ tion vessel.
  • the air arriving at +20 °C from room spaces is heated in the heat exchanger 2 to +30 °C. Thereafter this heated air yields its heat to the battery of the air- conditioning and heat recovery apparatus, whereafter it flows out.

Abstract

Appareil épurateur des gaz brûlés et récupérateur de la chaleur, dans lequel les gaz brûlés provenant d'une chaudière de chauffage (1) sont acheminés jusqu'à un échangeur thermique (2) où les gaz brûlés transfèrent leur chaleur à une substance, telle que de l'air, qui s'écoule du deuxième côté (3) de l'échangeur thermique. Le côté (5) à sortie d'air chaud de l'échangeur thermique est relié à un appareil à régénération récupérateur de la chaleur et climatiseur.
