In recent years, some advanced technologies and equipment have been introduced in cement production, especially large dry cement clinker production line.This paper aims to analyze the methods of energy saving and consumption reduction in cement low-temperature waste heat power plant based on the actual situation.
With the development of resource-saving and environment-friendly society, resource conservation and environmental protection are being practiced in various industries and fields.Taking cement low-temperature waste heat power plant as an example, cement low-temperature waste heat power generation plays an important and positive role in resource conservation and environmental protection.In this process, it is mainly to realize the understanding and analysis of cement low-temperature waste heat power plant according to the corresponding cycle parameters, thermal cycle system, waste gas heat saving mode and principle, and then continuously adopt a certain way to achieve energy resource saving and environmental protection.
1. The application of thermal cycle mode continuously improves the ability and level of electrical energy saving and consumption reduction in cement low-temperature waste heat power plant
In today's society, in more cement low-temperature waste heat power generation industry and enterprises, is constantly using the new thermal system model to gradually replace and replace the traditional system model, in energy saving and consumption has made great achievements.In the thermodynamic system mode, it can be roughly divided into three parts, namely, the power generation mode of compound flash supplementary gas pure waste heat, the power generation mode of single pressure non-supplementary gas pure waste heat, and the power generation mode of multi-pressure supplementary gas pure waste heat.No matter which thermodynamic system model has its corresponding technical characteristics, it can play an important role in promoting the conservation of resources and environmental protection, and realizing sustainable and healthy development.
In the thermodynamic system model, its technology also has its own technical characteristics compared with the previous traditional model.For example, the main steam parameters of the steam system have their own characteristics, including the temperature must meet the relevant requirements, i.e., 260 ℃ -350 ℃, and the pressure value must be maintained in the range of 0.699 ~ 1.47MPa.At the same time, the corresponding discharge device must meet certain requirements.For example, when setting up SP boiler, PC kiln tail preheater can be used to discharge the exhaust gas whose temperature is lower than 360℃, and at the same time, exhaust gas whose temperature is lower than 600℃ can be discharged through some other devices.By combining the two devices organically, the formation of steam turbine has a great impact on its energy saving and consumption reduction.These two technologies have their own similarities and limitations.However, if these two technologies can be mixed together, it is believed that they will surely save energy and reduce consumption in cement low-temperature waste heat power plant.
2. Continuous improvement of pure low-temperature waste heat power generation technology of cement kiln can also effectively promote the implementation of energy saving and consumption reduction
Energy saving and consumption reduction plays a very important and positive role in the development of today's society.To really promote the cement low-temperature waste heat power plant energy conservation and consumption reduction, we need to continue to study from the technical level, and constantly explore new measures and new methods of energy conservation and consumption reduction.
Improving cement kiln pure low temperature waste heat power generation technology is one of the commonly used technologies in today's society.It is mainly to give full play to its own unique thermal cycle system, waste gas heating mode and cycle parameters of the main characteristics, to maximize the realization of energy saving and emission reduction purposes.For example, an exhaust gas extraction port of 400℃ is set near the feed end of the cooling machine, and an exhaust gas extraction port that can discharge or extract the exhaust gas of 280℃ is installed in the key part of the cooling machine.In this link, it can effectively change the traditional exhaust gas extraction method of kiln head clinker cooler, avoid the disadvantages of the original extraction method to the greatest extent, and realize the conservation of resources and energy and environmental protection to the greatest extent.At the same time, when the preheater system is used in the end of the kiln, the gas in a certain temperature can be effectively discharged, and C2 and cyclone tube can be used to continuously process C1 and cyclone tube inlet, so as to save resources and protect the environment to the greatest extent.Whether the corresponding device is installed in the corresponding position or the preheater system of kiln tail is constantly improved, it has a crucial impact on the development of the whole society.If the two can be organically combined, give full play to the advantages of the two parties, and strive to overcome their own shortcomings, it will have more far-reaching significance for improving the energy conservation and emission reduction of cement low-temperature waste heat power plant.
3. Continuous application of various technologies in practice is conducive to the realization of electrical energy saving and consumption reduction
There are many ways to save energy and reduce consumption in cement low-temperature waste heat power plant.If all kinds of technical methods can be effectively applied in practice, it is also conducive to the maximum promotion of cement low-temperature waste heat power plant electrical energy saving and consumption reduction.For example, an enterprise in pengzhou city, zhejiang province continuously adopts the pure medium and low temperature waste heat power generation technology with elevated type and no air supplement, which plays an important positive role in promoting the energy conservation and emission reduction of electric power to some extent.In addition, some other engineering techniques have been applied in some other low-temperature waste heat power plants, which are conducive to the development of production to the greatest extent.
In addition, there are many effective ways to save energy and reduce consumption in cement low-temperature waste heat power plant, which need to be studied and explored continuously.It is hoped that through the continuous research on this problem, we can make a contribution to truly solving the electrical energy saving and consumption reduction of cement low-temperature waste heat power plant.
Cement low-temperature waste heat power plant belongs to the important production field of the country, which has a very important impact on the development of society and people's life.Therefore, if the electric energy saving and consumption reduction can be realized in this field, it will certainly promote the social economy.Therefore, it is very important to study the methods of electrical energy saving and consumption reduction in this field.Through the research on several electric energy saving and emission reduction methods of cement low-temperature waste heat power plant in this paper, it is believed that it will play an important role in promoting the supply-side structural reform and the sustainable development of society.
