Recently, the Ministry of Industry and Information Technology and the Jiangxi Provincial Department of Industry and Information Technology announced the list of national and provincial green manufacturing in 2023, and many enterprises in Nanchang were selected. So far, Nanchang has cultivated 21 national green factories and 30 provincial green factories, which means that new progress has been made in the construction of the city's green manufacturing system.
In Ganjiang Conch Cement Co., Ltd., a "green factory in Jiangxi Province", rows of blue photovoltaic panels are shining in the sunshine, and the scenery is easily photographed. Workers said that they felt very happy to work in the factory area surrounded by fresh air and green plants.
Nanchang Cemented Carbide Co., Ltd. is an enterprise producing tungsten powder products, cemented carbide and precision tools, where there is no noise rumbling, no dust rolling, but full of green vitality. The company has a plant area of 218,000 square meters, a green area of 24,200 square meters and a greening rate of 11.1%, and has been awarded provincial and national green factories successively. The company vigorously selects green technology, technology and equipment, promotes green and intelligent production lines, intensifies automation transformation, continuously optimizes industrial structure, and explores the way of harmonious coexistence of production, operation and ecological environment. At the same time, the company has injected green elements into the whole process of production and operation, invested nearly 6 million yuan to carry out clean (rain) sewage diversion and wastewater treatment projects, further strengthen energy management, conduct annual energy audits, timely improve technical parameters according to expert opinions, and reduce energy waste. Wang Pengchao is the leader of the company's green factory project implementation team, and participates in the whole process of the green transformation of the factory environment. Wang Pengchao told reporters: "You can see the green when you look up in the factory, and your working mood will be better."
In Jiangxi Ganjiang Conch Cement Co., Ltd., rows of blue photovoltaic panels are shining in the sunshine, and the scenery can be easily photographed. Workers said that they felt very happy to work in the factory area surrounded by fresh air and green plants. Nowadays, more and more enterprises are promoting green transformation, and the internal and external environment of the park is full of vitality. Taking Nanchang Jingkai District as an example, one or two enterprises are evaluated as green factories every year, and the whole park is like a big garden. Some experts pointed out that the garden-style factory ensures a higher greening rate, can play a role in reducing noise, so that the factory maintains a good ecology, but also can make the workers in the factory feel happy and relax after work. The green kinetic energy
green factory on the
production line not only looks at the "face value", but also at the "green content".
Introducing advanced green technology and equipment is the starting point for Jiangxi Ganjiang Conch Cement Co., Ltd. to become "green". Ganjiang Conch relies on technological innovation, energy saving and emission reduction, and recycling to promote the development of green and low-carbon enterprises. Referring to the technological innovation of Ganjiang Conch, Zhu Qingyong, a staff member of the company's production technology department, opened the conversation box. He told reporters that in addition to the realization of 0.93 MW photovoltaic project grid-connected power generation, the company has also carried out a lot of work to improve the level of energy saving and consumption reduction, successfully implemented the external circuit relocation, the length of the line was shortened from 15 km to 1 km, and the annual light loss can save 2 million kilowatt-hours of electricity; Each mill can save 850,000 kilowatt-hours of electricity throughout the year through the lightening of the mill liner and the frequency conversion transformation of the mill tail fan; there are also the transformation of the ventilation duct of the chute air box and the transformation of the energy-saving water pump. Through continuous technical transformation, power consumption research and optimization of operation, the company's production and operation quality has been further improved, and the power consumption of grinding process has been continuously reduced for ten years.
Jiangxi Ganzhao Optoelectronics Co., Ltd. is an enterprise engaged in the manufacturing of optoelectronic epitaxial wafers and chips. In order to ensure the yield of chip products, the workshop needs to maintain constant temperature and humidity all the year round, and the air conditioning system has become the company's largest energy consumption. In order to save energy and reduce emissions, reduce costs and increase efficiency, the company has made every effort to build a green factory by strengthening management and technological transformation.
Not long ago, Ganzhao Optoelectronics was awarded the national green factory. Shang Gu, deputy director of operation of the company's plant equipment department, said: "We have carried out projects such as the transformation of new air outlets for central air conditioning, heat recovery and cold recovery. In 2022, 473.17 tons of standard coal will be saved, and the energy consumption per unit output value will be reduced by 4.99%." The green concept
in
research and development assembles an air conditioning compressor in 6 seconds, which can still start normally in the harsh environment of minus 30 degrees Celsius-this is the performance of the air conditioning compressor produced by the green factory Nanchang Haili Electrical Appliances Co., Ltd. This kind of air conditioning compressor is widely praised by the market and has strong competitiveness.
Haili Electrical Appliances is not only advanced in technology, but also full of green elements. According to reports, in the 51 processes of compressor production, Haili Electrical Appliances has carried out green transformation of more than 20 processes, and further increased the proportion of green materials through the development of plastic instead of steel process and the research and application of new environmental protection electroplating process. By infiltrating the
green concept into product research and development, the cost and energy consumption of enterprises have been reduced, and the quality and competitiveness of products have been improved. Jiangling Group New Energy Automobile Co., Ltd., a state-level green factory announced in 2023, has few workers in the painting workshop, but presents a busy scene. Dozens of intelligent paint spraying robots are working precisely, from vehicle identification, color confirmation to paint switching and spraying operations, all processes are running in an orderly manner.
It is understood that Jiangling Group New Energy Automobile Co., Ltd. has evaluated the energy saving, low carbon and sustainability of the factory, rationally used carbon emission reduction technology and green manufacturing technology, and explored a carbon reduction path that can reduce carbon in production links, coordinate carbon reduction in logistics, and ultimately benefit the whole manufacturing process. At the same time, enterprises realize the digitalization and intellectualization of production process, energy management and plant management through intelligent systems, realize the unmanned, efficient and traceable production process, and greatly improve the production efficiency and energy efficiency of factories.
"Green factories promote enterprises to continuously optimize the carbon footprint of products and carbon emissions of factories, which is conducive to reducing the energy consumption of a single product.". In 2023, the energy consumption of a single product was reduced by more than 40%, and the production efficiency was increased by 37.5%. The head of the painting workshop said. The increasing number of
green factories is the epitome of Nanchang's implementation of the concept of green industrial development and the realization of green transformation and upgrading. The relevant person in charge of Nanchang Bureau of Industry and Information Technology said that the city is brewing a new incentive policy, which will continue to take enterprises as the main body, take standards as the guide, follow the evaluation standards of green factories, parks and supply chains, follow the principles of intensive land use, clean production, waste recycling and low-carbon energy, and encourage enterprises to create green factories to promote green production and green consumption.
