Description
Technical field
The present invention relates to a kind of energy-saving monitoring method, specifically a kind of method for supervising of dry cement production line energy-saving emission reduction real-time quantization.
Background technology
At present, China's cement industry is extensive calculating for the method for Energy Consumption Evaluation always, " thermal technology's demarcation " data when mainly being completed operation according to production line; Perhaps adopt every month annual accounting method of calculating general ledger to try to achieve; That is: with having produced how many grogs, use how many coals, tried to achieve how many coals of per kilogram grog, multiply by the average thermal value of coal per kilogram again, tried to achieve per kilogram heat consumption of clinker value.Cement industry energy resource consumption, disposal of pollutants, especially coal consumption mainly concentrate on rotary kiln and dore furnace.Because the production capacity of new type nonaqueous cement production line is big, one day output is all in the level of a few kiloton grogs, and its kiln will be burnt the bunker coal of kiloton in one day.Except measuring exactly the coal consumption, fully whether bunker coal burning, and whether the heat energy that burning produces is fully used, and directly influences the hear rate of cement clinker.The expert points out that excess air has a significant impact the burning of kiln.Lack of air will cause the kiln internal combustion incomplete, form CO in waste gas.Per kilogram carbon generates the heat that CO discharged and has only 30% of generation CO2.Contain 0.1% CO in the new type dry kiln waste gas, the per kilogram cement clinker will increase the hear rate loss of about 27 kilojoules.On the contrary, if excess air is too much, O2 content increases (greater than 2.5%) in the waste gas, and unnecessary air is just overflowed with waste gas after also being heated to exhaust gas temperature, also causes thermal loss.Under normal circumstances, oxygen content should be between 0.7～1.5% in the kiln tail gas.NO content size in the waste gas, the height of the temperature of combustion in the reflection kiln if NO is too high, illustrates that not only the clinker burning temperature is too high in the kiln, causes the grog burning; But also will cause environmental pollution.In order to compare the control energy consumption of science, external cement production enterprise or external owner install and use rotary kiln and dore furnace high-temp waste gas analytical equipment.The operating personnel of enterprise change according to the composition of the CO in the waste gas, O2, NO, regulate the coal of using of rotary kiln and dore furnace, give full play to the technical advantage of New Type Dry-process Cement Production, realize the efficient energy-saving high and stable yields.Because the exhaust gas temperature height (up to 1300～1500 ℃) that the cement industry fuel combustion generates, dust content (reaches 2000g/m greatly
3More than), abominable measurement environment is added online exhaust gas constituents analysis and is mainly relied on import with measuring equipment, price height (about 140～1,600,000 yuan/cover) not only, and also technology is immature, operating cost also very high (about 100,000 yuan/year).Cause the domestic new dry process water production line that accounts for sum 90%, because the restriction of examined technology and equipment, being in the actual consumption situation of not understanding and not monitoring manufacture of cement, let alone how saving in process of production and reduced the consumption of the energy, can only be what to burn what are calculated.Excess air increases, and calcining heat is too high, has all increased the discharge amount of exhaust gas of cement producing line, and dust discharge amount also increases; Pollutant SO2 and NO2 also increase.Exhaust gas temperature height (up to 1300～1500 ℃), dust content (reaches 2000g/m greatly
3More than) domestic more than 1500 new type nonaqueous cement production lines have only less than 10% to use CO, the O2 of the high-temperature gas that the analytic combustion of high-temperature gas analytical technology generates, operation that the NO composition instructs kiln, stove at present, CEMS (fume emission detection) technology of having only the transplanting of minority cement production enterprise to use electric power enterprise to use is used for carrying out the disposal of pollutants monitoring of new type nonaqueous cement production line.
By retrieval, in cement production process, but on-line continuous is measured excess air coefficient α, kilogram heat consumption of clinker, the rotary kiln thermal efficiency of cement industry kiln, and at home and abroad not seeing in the document has identical report.
Summary of the invention
Goal of the invention of the present invention is will solve prior art to the consumption of the cement kiln energy, the deficiency of disposal of pollutants detection technique, a kind of exhaust gas constituents content that generates by the burning of real-time quantization monitoring cement producing line is provided, monitor consumption, the disposal of pollutants of the cement kiln energy, the method for supervising of the dry cement production line energy-saving emission reduction real-time quantization that monitoring method is simple accurately, monitoring cost is low.
Realize the foregoing invention purpose by the following technical solutions: a kind of method for supervising of dry cement production line energy-saving emission reduction real-time quantization, described cement producing line comprises rotary kiln, dore furnace with the rotary kiln connection, primary heater, chimney, also comprise the high-temperature gas analytical equipment that uses in the method for supervising, computing machine and gas analyzer and dust measurement, described method for supervising is:
