A hole 16d is formed. Or you may form the droplet collection part 16 with a punching metal (refer FIG.2 (c)) or a metal-mesh.

  The smoke eliminating / deodorizing apparatus 10 also includes a droplet receiving container 20 disposed immediately below the opening 16 a of the droplet collecting unit 16. The first member 16b of the droplet collecting unit 16 is preferably formed of a member having a flat upper surface so that the droplets can be easily collected in the droplet receiving container 20. More preferably, it is preferable to provide a groove on the upper surface of the first member 16b of the droplet collecting section 16 in order to make it easier to collect droplets.

  The smoke eliminating / deodorizing apparatus 10 also includes an injector 22 disposed inside the cylindrical body 14. The injector 22 has an elongated cylindrical shape, and a plurality of nozzles 22a for injecting the carbon aqueous solution in a mist shape are provided on the peripheral surface thereof. The diameter of the nozzle 22a is preferably about 0.001 mm so that the carbon aqueous solution can be sprayed in a mist form.

  The smoke eliminator / deodorizer 10 also includes a carbon aqueous solution storage tank 24 disposed outside the flue, and the carbon aqueous solution storage tank 24 contains carbon particles obtained by firing and pulverizing plants such as rice husks. A carbon aqueous solution formed by mixing with water is filled. Preferably, a filter 24 a is disposed adjacent to the upper part of the aqueous carbon solution storage tank 24.

  The carbon aqueous solution storage tank 24 communicates with the injector 22 via the first conduit 26, and the carbon aqueous solution is passed through the first conduit 26 by the pump 28 disposed in the carbon aqueous solution reservoir 24. It is designed to be pumped to.
