Afterwards, the particles are coagulated and precipitated, and the suspended particles in the smoke are discharged by a stream of water.

[Embodiments of the invention]

The smoke produced by combustion of solid, gas, liquid, etc. as fuel is diffused and mixed with fog water, which condenses and lowers the temperature of the smoke. At this time, suspended particles in the smoke, such as ash powder and impurities, are precipitated by the spray of mist water and condensed, and are also flowed out with the running water.
In this way, the repeated circulation treatment of the set purifies the smoke dust, and the purified smoke is then discharged.This treatment method reduces the smoke dust in the combustion smoke to the lowest level. This is a decrease.

Further, in the smoke dust purification method of the present invention, when the smoke generated by combustion enters the device of the present invention through the guide of the smoke pipe, it is introduced into the device of the present invention by the power of the motor and is then diffused by another power source. A stirred mixture is formed with the resource fog water, and the fog water forcibly lowers the temperature of the smoke, and the suspended particles in the smoke and the fog water are combined to coagulate and precipitate, which is then discharged by water flow. By connecting one or more of these in series according to the present invention, the smoke is subjected to the above-mentioned process several times or more to coagulate and precipitate, thereby achieving the purpose of purifying smoke and dust.
