| The development of national economy in China results in a rapidly rising energy consumption. Huge consumption of coal causes serious pollution in the atmosphere with pollutants such as smoke, dust and SO2. Many environment protectors have done much research to decrease and control air pollution. This paper reviews the current energy consumption, its influence on environment and the clean coal technology of industrial kiln and furnace. It puts forward the adjustment and optimization of energy construction on the strategy of energy application and the development and application of the new clean coal technology. To satisfy the demand of the sustainable development, the emission amount of pollutants will be decreased to the minimum by sifting source, de-sulfuring in coal, cleaner burning and the end treatment. The smoke contamination of industrial kiln and furnace is one of the main factors of polluting the atmosphere. And the main pollutants include smoke dust, SO2 and blackness. At present, the control methods of pollutants of industrial kiln and furnace use dry method (e.g. absorption, cyclone, bag filter etc.), wet method (e.g. sprinkling, scrubbing, water-film absorption etc.), and electrostatic precipitators, but every method mentioned above has its disadvantages. Especially, the removal of fine particle cannot meet the need of practical operating mode conditions, in which there are higher temperature, a large amount of smoke dust and higher blackness of the smoke emitted by industrial kiln and furnace. We try to find a new method of improving the purification effect. By analyzing the smoke quality emitted by burning of coal, the SO2 formation characteristic and motion law of SO2, we utilize the remaining heat of higher temperature smoke to produce many small droplets and vapor being acted upon by the high-velocity gas stream and then put forward the growing mode of fine particle which is fog, droplets containing fine particles—forming nuclear dust—a cohesion resulting in the formation of bigger "balls". It supplies the theory foundation for the removal of fine particle. On the basis of nuclear cohesion principle, fine particle's diameter becomes bigger, and the forecasting of particle diameter is verified by measuring the particle diameter. By analyzing the power attained by the smoke obtained, it is also posed that the mode of fine particle's cohesion and absorption and its divided-sections process. Thus, the removal efficiency of dust and sulfur is increased. By analyzing the absorbing SO2 property of absorption lye, we conclude that the following functional equation, which supplies the design foundation for the higher-efficiency device removing sulfur and dust.This paper investigated and designed the revolving and shooting spray nozzle and also study and verify the index of spray intensity, atomization effect etc. We find the equation of spray intensity and diameter, which supplies the parameters for the practical application of spray nozzle. According to the theory analysis and the obtaining designing parameters, we have designed the higher-efficiency device for removing sulfur and dust. The device is divided into three parts: sprinkling part, lashing part and "S" passage part. In sprinkling part, we adopt the spray nozzle which has high-atomization effect. "R" plate is installed in the lashing part so that it can produce more fine droplets which can strengthen the mutual contacts of gas, liquid and solid. The removal efficiency of sulfur and dust is promoted in "S" passage. According to the law of mass conservation, electric neutralization principle, infiltrate-surface renewal theory, as well as construction of GR, we built the dynamics mode of the simultaneity of the heat transfer and mass transfer in the GR purifying device. In the GR purification device, the pressure drop range is greater than 500Pa and less than 1000Pa. As the amount of gas getting into the device increases, the pressure also increases. When the gas velocity is constant, the main factor in the...
