With the rapid development of science and technology, the field of industry has been greatly improved. In today's increasingly fierce industrial development, the concept of green environmental protection and other energy saving has gradually penetrated into the industry production. At present, whether at home or abroad, the effect of energy saving and emission reduction in the metallurgical industry has increased the degree of concern. A large amount of energy is consumed in the production process of iron and steel metallurgy, and a large amount of heat is released in the production process. The secondary utilization of waste heat can bring good economic benefits to enterprises and also greatly help the energy conservation and emission reduction of the iron and steel metallurgy industry.

Petrochemical industry is the pillar industry of our country, including petroleum petrochemical and chemical industry, both of which maintained rapid growth in 2006. In recent years, the petrochemical industry has a serious overcapacity problem. The petrochemical industry, which has serious excess capacity, is still expanding its capacity, and some emerging industries are also showing signs of excess. Among them, urea, phosphate fertilizer and calcium carbide, which are closely related to people's production and life, all have serious overcapacity. The following recommendation report of Qianzhan Industry Research Institute gives an in-depth description of the current situation of the petrochemical industry market, the competitive landscape of leading enterprises and the future development trend of the petrochemical industry.

With the rapid development of industrialization, a large amount of organic waste gas is discharged, which harms the atmospheric environment and restricts the sustainable growth of economy. In this context, the prevention and control of organic waste gas pollution has aroused widespread attention in the society. Solving this problem is not only conducive to environmental protection, but also can achieve the effect of energy saving and emission reduction. It is of great significance for economic development.

Food drying is the process of removing food moisture from hot air after it evaporates. Food drying is one of the main technologies in food storage and processing. Most of the water in food is removed by drying technology to reduce water activity, inhibit the growth and reproduction of microorganisms, and prolong the storage period of food.

Copper clad plate manufacturing industry is a sunrise industry, it accompanies the development of electronic information, communication industry, has a broad prospect of development, its manufacturing technology is a multi-disciplinary cross, mutual penetration, mutual promotion of high and new technology. The glue solution used in the production of copper clad plate usually contains organic solvents, which are volatilized during the gluing process. The organic solvent itself has a high caloric value. In order not to pollute the environment, these solvents are sent to waste gas incinerators and incinerated at a high temperature of more than 760℃, at which almost all organic matter is destroyed 2, and then discharged without polluting the environment. The heat generated by combustion can be recovered and reused, which can be directly used as the heat source of the gluing machine, and can also be used as other, saving energy and cost.

In the continuous unit with cold rolled strip steel, galvanized strip steel as the substrate, after surface pretreatment (degreasing and chemical treatment), with the roller coating method, coated with one or more layers of liquid paint, after baking and cooling the sheet is coated steel plate. Because the coating can have a variety of different colors, it is customary to coat steel plate called color coated steel plate. In addition to the protective effect of zinc, the organic coating on the surface also plays the role of isolation protection and rust prevention, and the service life is longer than that of cold rolled plate.
Over the years, domestic iron and steel enterprises have made remarkable achievements in the process optimization of steel deep processing industry and the application of energy saving and emission reduction technology, especially for color coating and galvanized sheet production line projects by taking effective energy saving measures, energy saving and consumption reduction effect is remarkable.

At present, the vast majority of domestic steel, coking, chemical industry flue gas before discharge mostly spray or wet desulfurization, the temperature drops to 45℃-55℃, at this time the flue gas is usually saturated wet flue gas, flue gas contains a lot of water steam, water steam contains more soluble salt, SO3, gel dust, dust, etc. (are the main components of haze). If the flue gas is discharged directly from the chimney and enters the ambient air with a lower temperature, the water vapor in the flue gas will condense and form a wet plume in the process of reducing the temperature of the flue gas because the saturation humidity of the ambient air is relatively low.

Building materials industry is an important material industry in China. Building materials products include building materials and products, non-metallic minerals and products, inorganic non-metallic new materials three categories, widely used in construction, military, environmental protection, high-tech industry and people's life and other fields.

Lithium-ion batteries have been widely used in portable electrical appliances such as laptops, video cameras and mobile communications for their unique performance advantages. The large-capacity lithium-ion battery developed has been tested in electric vehicles and is expected to become one of the main power sources for electric vehicles in the 21st century, and will have applications in artificial satellites, aerospace and energy storage. With the shortage of energy and the pressure of environmental protection in the world. Lithium is widely used in electric vehicle industry, especially the appearance of lithium iron phosphate battery, which promotes the development and application of lithium battery industry.

Glass fiber is a very good substitute material for metal materials. With the rapid development of market economy, glass fiber has become an essential raw material for construction, transportation, electronics, electricity, chemical industry, metallurgy, environmental protection, national defense and other industries. Because of its wide application in many fields, glass fiber has been paid more and more attention.
