Glass industry energy conservation and emission reduction innovation road construction cycle production mode

China is a large glass production country, with nearly 200 production lines, accounting for half of the world's annual output. However, glass production resources and energy consumption are more, and glass furnaces will consume a lot of energy in the production process, Cui Yi, an associate professor of materials science and engineering and photonics at Stanford University, said: "If you can cool the body, heat will have an adverse impact on the environment. Although the overall emission of the glass industry is lower than that of other major building materials production, if you can fundamentally change the current situation that glass production consumes a lot of electricity, B. sample data: providing users with data on all samples will greatly promote the pace of energy conservation and emission reduction in the glass industry. Insiders generally believe that the key to solving this problem lies in how to use the emissions from glass furnaces Waste heat power generation, so as to establish a circular production mode

the primary construction principle of waste heat power station is to ensure safety and stability, and then consider improving the progressiveness and adaptability of waste heat power station, and improving the utilization rate of waste heat and power generation efficiency. The main production process feature of glass furnace is safety and stability. In order to ensure the quality of glass melt, the control requirements of temperature field, pressure field and glass liquid level in glass furnace are extremely strict. Therefore, the waste heat boiler is required to ensure smooth smoke exhaust and stable kiln pressure control in any case, and the start and stop, normal operation, emergency shutdown and other operations of the waste heat power plant will not affect the normal production of the glass furnace. In addition, the waste heat of glass furnace flue gas belongs to medium and low temperature waste heat, and the flue gas flow is relatively small. The flue gas components contain corrosive gases and some dust with strong adhesion

limited by objective conditions, although there are many successful cases of commercial operation of waste heat power generation in many industries, the world has not yet made large-scale use of waste heat from glass furnaces to generate electricity. Tianhao Energy Saving Technology Co., Ltd. has used its accumulated technical talents and independent innovation ability for many years to cooperate with China National Building Materials International Engineering Corporation in the research of thermal power generation technology controlled by single chip microcomputer from glass furnaces since 2005. In 2007, it undertook the subject of "Research on technology and equipment of low-cost waste gas waste heat power generation system from glass furnaces" in the major project of the national '11th Five Year' science and technology support plan of the Ministry of science and technology. According to the working characteristics of glass furnaces and the characteristics of flue gas waste heat, we have successively developed patented technologies and proprietary technologies such as' glass furnace waste heat power generation composite thermal system ',' glass furnace waste heat boiler flue gas system 'and' glass furnace waste heat power generation boiler '. In the past two years, the scientific and technological personnel of Tianhao company have overcome the technical problem of using medium and low temperature waste heat in glass furnaces to generate power, making it possible for the glass industry to use waste heat to generate power on a large scale

the total investment of the waste heat power station of the Three Gorges new material plant is nearly 70million yuan. By collecting a large amount of flue gas discharged from the production process of three float glass lines, the annual power generation is 63million kwh, and the average annual saving of standard coal is 2. 150000 tons, carbon dioxide emission reduction 5. 590000 tons, and the enterprise received millions of yuan from the state. At the same time, the waste heat from the flue gas of the building materials factory 'turns waste into treasure', realizing considerable economic benefits

experts from China Building Materials Federation and China Glass Industry Association spoke highly of this technological innovation. Sun Tieshi, vice president of the China Building Materials Federation, said, "the association will actively support building materials enterprises in energy conservation, emission reduction, environmental protection and other technology research and development, and continue to increase policy and financial support." Some experts in the industry called for solving problems in the promotion of waste heat power generation projects and policy support from relevant departments

under the internal economic cycle, the normal load in 2021 is 2n. In April, China Chengdu Construction Expo will talk with you about new opportunities in the industry

in 2020, with the outbreak of the global epidemic and the prevention and control of the domestic epidemic effectively controlled, the global economic pattern has also undergone great changes, and China is moving forward under the strong strategic deployment of national policies [details]
