Actively explore the low-carbon development path of Guangdong glass industry

in recent years, the rapid economic development has not only brought material civilization to people, but also consumed a lot of energy resources, and also caused more and more serious environmental pollution. The lack of resources, the depletion of energy and the destruction of the environment have become the bottlenecks restricting economic development. Saving energy, reducing consumption and reducing pollution are the common problems faced by economic construction, and low-carbon economy has become the feature of a new round of economic development<1.2. The repeatability caused by the problem of the main swing bearing of the experimental machine is out of tolerance. Because the main swing bearing is in a relatively sealed environment/p>

glass production and glass processing need to consume a lot of energy. The glass industry is one of the key energy consuming industries concerned by all sectors of society. How to promote the sustainable and rapid development of the glass industry under the condition of low-carbon economy is a problem that the majority of glass workers must think about

in recent years, Guangdong glass has developed rapidly, and remarkable achievements have been made in both flat glass and deep processed glass. In 2009, Guangdong's flat glass output reached 71 million weight boxes, accounting for 13% to 14% of the national flat glass output, of which float glass reached 64 million weight boxes, accounting for 90% of the provincial flat glass output; Processed glass products include construction engineering glass, automobile safety glass, home appliance furniture glass, electrical instrument glass, decorative art glass, etc. the deep processing rate of glass is more than 45%, and the output value of processed glass exceeds 18billion yuan. The energy consumption of flat glass production in the province has reached 1.05 million tons of standard coal, and the average energy consumption per weight box of flat glass is 14. 5 kilograms of standard coal, plus the energy consumption of glass deep processing, the production energy consumption of the glass industry in Guangdong Province is about 1.5 million tons of standard coal

the fuel used in glass production in Guangdong Province is mainly heavy oil, and the energy used in glass processing is mainly electricity. Guangdong is a province with energy shortage. The contradiction between supply and demand is very prominent, whether it is heavy oil or electricity. In particular, the price of heavy oil has soared, causing the continuous rise of glass production costs, which has seriously affected the production and development of glass. The implementation of low-carbon economy is a severe test for the glass industry. In order to survive and develop in a low-carbon economy, we must strive to reduce the energy consumption of glass cycle life

glass cycle life energy consumption refers to the energy consumption of glass in the whole process of raw material input, production, processing, use, maintenance, failure, scrap and recycling. In order to pursue the lowest energy consumption in the glass cycle life, it is necessary to adjust the glass industrial structure, and control the energy conservation in all links of glass production, processing and use, so as to realize the comprehensive utilization of energy

adjust the industrial structure and strengthen the elimination of backward enterprises

up to now, Guangdong Province has 13 flat glass production enterprises, including 6 float glass enterprises and 7 lattice glass enterprises. The production capacity of flat glass in the province is 72.5 million weight boxes, of which float glass enterprises have a total of 18 float glass furnaces, with a daily melting capacity of 1. 10000 tons, the average daily melting volume of each float glass furnace is 610 tons, and the largest float glass furnace has a daily melting volume of about 900 tons. The production capacity of float glass is 65million weight boxes, and the average production capacity is 10.83 million weight boxes. There are 11 lattice glass kilns, with a daily melting capacity of 1250 tons. The production capacity of lattice glass is 7.5 million weight boxes, and the average production capacity is 1.07 million weight boxes. The proportion of backward production capacity accounts for about 10%. Although the proportion of backward glass production capacity in Guangdong Province is small, but the production energy consumption is high and the quality is poor, we should actively take various effective measures to accelerate the elimination of backward production capacity, and strive to completely eliminate backward production capacity by the end of this year according to the national plan to eliminate backward production capacity

and float glass also has the phenomenon of single product structure and serious homogenization, so the adjustment of product structure should be strengthened

we should give full play to the respective technological and market advantages of float glass enterprises, develop and produce ultra thick, ultra-thin, ultra white and other special-purpose glasses, and reduce the competition among float glass enterprises. Backward glass processing technology and workshop glass processing enterprises should be phased out to ensure the quality of processed glass products and reduce the energy consumption of processed glass production

take effective measures to reduce various energy consumption

the glass production process is a typical thermal process. Attention should be paid to ensure the thermal stability of the production process, strive to improve the thermal efficiency, and implement the control of energy consumption in all links

1。 Strengthen the management of materials with the function of automatic zero adjustment in this unit, and do a good job in the homogenization and batching of raw materials. Ensuring the uniform and stable quality of raw materials into the kiln to ensure the stability of the thermal system of the furnace is conducive to improving the yield and quality level of products, so as to reduce production energy consumption

2。 Actively adopt oxygen enriched combustion and total oxygen combustion technology. Using oxygen enriched combustion or total oxygen combustion technology in glass furnace can not only promote the complete combustion of fuel and improve the utilization rate of energy, but also help to stabilize the thermal system in the kiln

3。 Recycle waste glass. The recycling of waste glass can not only reduce waste emissions, but also help to reduce the melting temperature of materials and save energy and consumption when used with raw materials

4。 The kiln body and all interfaces shall be well insulated to reduce heat loss

5。 Waste heat power generation and other technologies are used for the recovery and utilization of waste heat from kiln tail gas

6。 Formulate energy consumption control indicators for each process, and strengthen the management and monitoring of energy consumption in each link. Energy consumption control indicators and comprehensive energy consumption of glass production should be formulated from various processes such as material transportation, mixing, melting, traction molding, cutting, packaging, etc., and monitoring and control should be carried out according to the specified cycle and frequency to ensure that the energy consumption of each process is under control and reaches the energy consumption control indicators

according to different products, the processing procedures of deep processed glass are also different, and the energy consumption in the processing process is mainly power consumption. Various new technologies, equipment and processes should be actively applied to reduce the power consumption of each processing procedure. At the same time, we should also strengthen the control of the use of glass chips, and strive to improve the utilization rate of glass chips and the yield of the production process, so as to meet the requirements of low-carbon production

the use of glass usually does not consume energy, but because glass has good heat conduction characteristics, it cannot play a good role in heat insulation. In some cases, it consumes energy in a sense, so its use is limited in many cases, such as ordinary flat glass directly used in buildings can not play the effect of heat insulation and heat preservation. In recent years, the state has vigorously promoted energy-saving buildings as an important measure for enterprises to speed up the butterfly change and soar to a low-carbon economy. In order to fully meet the requirements of energy-saving buildings, glass as an important building material should vigorously develop new energy-saving glass products such as Low-E glass, insulating glass, Low-E insulating glass and so on

these new energy-saving glass products not only have good thermal insulation performance, but also have good safety and sound insulation performance, and are widely used in glass doors and windows and building partitions

energy saving glass is widely used in building engineering, especially in energy-saving buildings. Energy saving glass has a very broad prospect in building energy conservation. All glass enterprises should pay attention to the production quality control of energy-saving glass, ensure that all performances within the product cycle life fully meet the requirements of energy-saving buildings, and constantly develop new products to improve the energy-saving effect of products, Only in this way can architectural engineering glass get faster development in low-carbon economy

seize the favorable opportunity to vigorously develop emerging industries

developing new energy and using clean energy are the requirements of low-carbon economic development. Using the high transmittance of glass to produce solar glass, which can be applied to buildings and other projects to convert light energy into electric energy, can not only meet the effect of building decoration, but also provide electric energy for lighting, air conditioning or heating for buildings, and can save a lot of energy for the society. Solar glass is not only an important direction of glass development in the future, but also a new opportunity for glass development under the condition of low-carbon economy. Flat glass and engineering glass enterprises should fully seize this favorable opportunity, do a good job in product structure adjustment, vigorously develop ultra white glass, strive to reduce production costs, and promote the popularization and application of solar glass

in addition, we should fully explore and make use of the characteristics of glass in terms of high strength, wear resistance, glittering and translucent, and develop various new glass products. Further promote the wide use of glass in construction engineering, decoration, home appliances and furniture, machinery and electronics, transportation, aerospace and navigation, national defense construction and other fields

low carbon economy is both a challenge and an opportunity for the glass industry in Guangdong Province. Guangdong has a number of powerful glass production, processing and glass machinery manufacturing enterprises, which provide a solid foundation for the continuous development of new technologies, equipment, processes and products for glass production under the conditions of low-carbon economy. Glass production enterprises should cooperate closely with glass R & D departments, colleges and universities and glass machinery enterprises, adhere to the road of combining production, study and research, constantly develop new technologies and products for glass production, constantly reduce energy consumption in glass cycle life, expand the application field of glass products, and promote the healthy and rapid development of glass in Guangdong Province under the condition of low-carbon economy
