Description

  The present invention relates to a negative ion generator, and more particularly to a negative ion generator using combustible exhaust gas.

  Conventionally, various devices for incinerating combustible waste are known.However, when combustible materials are burned in an incinerator with a simple structure, smoke containing dioxins and dust is released into the atmosphere due to incomplete combustion at low temperatures. There is a problem of being released.

  For this reason, in recent years, it has been widely practiced to burn soot generated in a furnace in a flue (gas discharge passage) by a burner (for example, Patent Document 1).

  On the other hand, in recent years, attention has been paid to negative ions, which are thought to provide a mental relaxation effect, and various ion generators capable of dispersing such negative ions into the air have been proposed (for example, Patent Document 2). .

  The gas discharge path 5 includes a first duct 6 connected to an upper part of the furnace body 1, a cyclone 7 connected to a downstream end of the first duct, and a second duct 8 connected to an upper part of the cyclone. The first duct 6 on the side is provided with a cylindrical ceramic 9 and a burner 10 for heating the ceramic, and constitutes a gas combustion section 11 for burning unburned components in the exhaust gas flowing from the furnace body 1. You. In this example, the ceramic 9 has a cylindrical shape as shown in FIG. 2, and has a porous three-dimensional network structure formed by firing a ceramic slurry adhered to a columnar foamed resin (soft polyurethane foam). The central portion is a hole 9A for passing exhaust gas.

  The ceramics 9 are accommodated in the first duct 6 with the holes 9A facing the flow direction of the exhaust gas. Preferably, the plurality of ceramics 9 are accommodated in the first duct 6 in an integrated state. On the other hand, the burner 10 is attached to the wall surface of the first duct 6 on the upstream side of the ceramic 9, and a flame is intermittently injected from the flame injection port toward the ceramic 9. As a result, the ceramic 9 is heated to 700 to 1500 ° C., and unburned components can be burned when exhaust gas passes through the holes 9A.

  Note that a heating wire (not shown) may be embedded in the ceramic 9 instead of the burner 10, and the heating wire may be externally energized. The ceramic 9 may be omitted and the gas burner may be constituted only by the burner 10, or the heating wire may be exposed on the wall surface of the first duct 6 to serve as the gas burner.

And barley stone are preferably used. These ores constantly release negative ions at low temperatures even at room temperature, and the amount of released negative ions increases especially when heated.

It should be noted that tourmaline has the most remarkable pyroelectricity and piezoelectricity among the hemimorphic crystal groups, and emits a large amount of negative ions due to the development of pyroelectricity by heating. This is a cyclosilicate mineral having three-coordinated boron (a mineral having a (SiO ₃ ) 6-membered ring anion due to the shared apex of a SiO ₄ tetrahedron), and the general formula of its chemical composition is [WX ₃ B ₃ Al ₃ (AlSi ₂ O ₉ ) ₃ (O, OH, F) ₄ ] (W = Na, Ca, X = Al, Fe ³⁺ , Li, Mg, Mn ²⁺ ) There are Drabite (W, X = Na, Mg), Squall (W, X = Na, Fe), Ubite (W, X = Ca, Mg), and Elbite (W, X = Na, Li).

Therefore, the water supplied from the water pipe 21 into the gas-liquid mixing unit 19 is stored in the gas-liquid mixing unit 19 as warm water containing negative ions. The hot water is taken out from the drain pipe 22 as bath water or the like, and the air filling the gas-liquid mixing section 19 is discharged from above the gas-liquid mixing section 19 through the exhaust pipe 23 in a state containing steam and negative ions. Will be released.

  Note that, also in this example, instead of the massive ore 18, a massive heat-resistant member holding the particles may be accommodated in the ion generation chamber 16. Further, the gas-liquid mixing section 19 is not limited to a box-shaped container, but may be a vent pipe 29 as shown in FIG. 4, for example, and the water guide pipe 21 may be connected to the bent portion.
