Abstract
The invention provides a high-efficiency energy-saving environmental-protection cement making machine set which is composed of an air separator 1, a liquid oxygen tank 2, a gasifier 3, a buffer tank 4, a heater 5, a pressure buffer tank 6 and a cement making machine set 9, wherein the cement making machine set 9 comprises a preheater 7 and a rotary kiln 8. The invention is characterized in that aliquid oxygen outlet tube of the air separator 1 is connected with an inlet tube of the liquid oxygen tank 2; an outlet tube of the liquid oxygen tank 2 is connected with an inlet tube of the gasifier 3; an outlet tube of the gasifier 3 is connected with an inlet tube of the buffer tank 4; the buffer tank 4 is provided with three outlet tubes which are respectively connected with a primary air tube of the preheater 7, a primary air tube of the rotary kiln 8 and an inlet tube of the heater 5; an outlet tube of the heater 5 is connected with an inlet tube of the pressure buffer tank 6; and the pressure buffer tank 6 is provided with two outlet tubes which are respectively connected with a secondary air tube of the preheater 7 and a secondary air tube of the rotary kiln 8. Excessive pure oxygen, which is used for improving combustion instead of air, can enable coal to be completely combusted, so that the instantaneous effective combustion rate of the coal achieves the upper limit value; and thus, the total amount of gas media in the reaction process is reduced by 79%, the heat quantity carried away by tail gas is reduced by 79%, and no oxynitride is in the tail gas since no nitrogen exists in the combustion process. By using the invention, the energy is saved by 80%, and the emission is reduced by 95%.
Description
Technical field
The present invention relates to dry method, wet-process cement ME and equipment.
Background technology
In the existing cement manufacturing process, the heat during cement clinker burns till is all from the heat of coal with the air combustion generation; The pure coal of 12 grams contains 1 mole of carbon atom, that is the individual carbon atom of 6.023 * 10 (23 powers), is exactly carbon containing 51.8% meager coal; The mixture of 3.120 * 10 (23 power) individual carbon atoms and other solid impurities is also arranged, and coal dust is thin again, also is several thousand, several ten thousand carbon atoms and impurity blended solid particulate; Or even hundreds of thousands of, millions of, several ten million carbon atoms and impurity blended solid particulate, and in the burning situation of high-temperature, it is individual that the oxygen molecule that only contains in 1 mole air is approximately 0.0169 * 10 (23 power); Coal particle to moving ahead, has only short several second so coal is detained with 20～30 meter per second speed in preheater and rotary kiln, so; In incendiary moment, carbon can not get the enough oxygen that its burning needs, and the result causes burning insufficient; Resource has been wasted in the waste of part carbon and carbon monoxide, has polluted environment; Though rate of combustion is not low, most of burning produces after leaving preheater and rotary kiln, and the heat of generation is useless to manufacture of cement, and harmful; Under hot environment, oxygen and nitrogen react, and generate a large amount of oxynitride; Contaminate environment, rate of combustion is not low on the surface, and in fact net heat is very limited; Net result causes the energy to waste in a large number, serious environment pollution, and production cost improves.
Summary of the invention
The object of the invention just provides a kind of cement of high-efficient energy-saving environment friendly and makes unit, replaces air-breathing, excessive purity oxygen and coal perfect combustion with excessive purity oxygen; Make the instantaneous effective rate of combustion of coal reach the upper limit (UL) value; The gaseous media total amount reduces 79% in the reaction process, and the heat that tail gas is taken away reduces 79%, does not have nitrogen in the combustion processes; Just do not have oxynitride in the tail gas, the advantage of the utility model: energy-conservation 80% reduces discharging 95%.The technical scheme of specifically dealing with problems: remove the gas blower that cement is made preheater, wind of rotary kiln, secondary air in the unit; An airduct of preheater, rotary kiln is connected with two outlet pipes of surge tank respectively; The secondary air channel of preheater, rotary kiln is connected with two outlet pipes of pressure surge tank respectively; The cement manufacturing unit composition that mainly comprises air trap, liquid oxygen jar, vaporizer, surge tank, well heater, pressure surge tank and comprise equipment such as preheater, rotary kiln; Wherein air trap liquid oxygen outlet pipe is connected with liquid oxygen jar inlet pipe; Liquid oxygen jar outlet pipe is connected with the vaporizer inlet pipe, and the vaporizer outlet pipe is connected with the surge tank inlet pipe, and surge tank has three outlet pipes; Three outlet pipes of surge tank are connected with an airduct of preheater, an airduct of rotary kiln, the inlet pipe of well heater respectively; The outlet pipe of well heater is connected with the pressure surge tank inlet pipe, and pressure surge tank has two outlet pipes, and two outlet pipes of pressure surge tank are connected with the secondary air channel of preheater, the secondary air channel of rotary kiln respectively.A kind of cement of high-efficient energy-saving environment friendly is made unit and is made unit 9 by air trap 1, liquid oxygen jar 2, vaporizer 3, surge tank 4, well heater 5, pressure surge tank 6 and the cement that comprises preheater 7, rotary kiln 8 and form; It is characterized in that: air trap 1 liquid oxygen outlet pipe is connected with liquid oxygen jar 2 inlet pipes; Liquid oxygen jar 2 outlet pipes are connected with vaporizer 3 inlet pipes; Vaporizer 3 outlet pipes are connected with surge tank 4 inlet pipes; Surge tank 4 has three outlet pipes, and 4 three outlet pipes of surge tank are connected with an airduct of preheater 7, an airduct of rotary kiln 8, the inlet pipe of well heater 5 respectively, and the outlet pipe of well heater 5 is connected with pressure surge tank 6 inlet pipes; Pressure surge tank 6 has two outlet pipes, and two outlet pipes of pressure surge tank 6 are connected with the secondary air channel of preheater 7, the secondary air channel of rotary kiln 8 respectively.
