Energy Consumption of Mining Sector Has Exceeded

Descripción

Among building materials industries, cement industry is the largest source in energy consumption. In order to solve environmental problems caused by the cement consumption, our country has began to use the cement rotary kiln to dispose of waste.Although energy resources in China are abundant, the amount of per capital is far lower than the world average level. At present, with the rapid development of industrialization, the energy consumption has exceeded what the environment be able to afford. And energy and environment problems has become the main problem restricting the development of our country’s economy.On the pyrolysis/gasification and incineration experience device of the self-designed air control hazardous wastes continuous feeding rotary kiln, the mechanical experts of Hongxing Machinery conducted pyrolysis experience research to the typical hazardous wastes fuel residue with high calorific value, and compared the pure pyrolysis experience results with the method of heat chemical equilibrium calculation.

During the twelfth five-year period, the government carried out a policy to encourage the recycling of waste. With its own development, the cement industry takes continuous exploration and intensify waste utilization in blast furnace cinder, desulfurization gypsum, coal gangue and so on, which had been discarded as waste things. At present, Henan Hongxing has used the cement rotary kiln to dispose of waste. Cement rotary kiln can make the waste harmless. In order to protect earth’s environment, we must promote the improvement of cement rotary kiln vigorously. The higher the production efficiency of cement rotary kiln and the utilization rate of waste, the less environmental hazards. The rotary kiln will be very popular with its good environmental effect in mechanical industry naturally. The simple structured cement rotary kiln is widely used in cement high-grade calcining, the equipment can also be used in the chemical and construction industries. Being convenient and reliable, the production process of the cement kiln has high operation rate and low damage, and its main parts are cylinder, support means, the kiln hood, sealing device and the kiln inlet sealing device. The sealing device which is fitted with coal burner, are depending on the calcining process. The kiln is equipped with a smoke chamber, waste heat power generation boilers, warm-up and pre-calciner. The cylinder has a certain inclination.
