Silicon carbide and other enterprises eliminated and emission reduction "led the" upgrading of Qinghai industry ".
There are economic experts point out that the most important thing to build China's economic upgrade is to pass four blocks, the first Dao is to catch up with the labor productivity of the second, third industry, the second Dao can develop the new strategic industries, cultivate new investment hot spots and economic growth points, and the energy consumption of the unit GDP will continue to decline greatly, and the situation of environmental pollution is obtained. The fourth hurdle: improve; improve service industry proportion. Therefore, the key to upgrading the industrial economy is to adjust and optimize the industrial structure and promote industrial transformation and upgrading. While adjusting the structure, not open around a stumbling block is the backward production capacity. Eliminating backward production capacity and energy saving technology transformation is the important link and the starting point of our work.
In Ganhetan Industrial Park, the reporter saw a different ferroalloy production enterprises -- Qinghai Belden Inc. Different from the past "silicon iron corridor" family smoke scene, ferroalloy production enterprises can also become a garden plant with green trees and shades and flowers and grass.
As the annual high pure ferrosilicon 300 thousand tons, the Belden Inc in Asia's largest high pure ferrosilicon production base has actively implemented projects such as the improvement of smoke and dust treatment and the waste heat generation of the mine heat furnace. In order to reduce the consumption of resources, reduce waste discharge and improve the efficiency of resource output, the Belden Inc has stepped out a way of enterprise development and clean development.
If the iron alloy enterprises with high energy carrying capacity can't effectively save energy and reduce consumption, they will not survive, let alone development. Li Xiangdong, the deputy general manager of the company, told reporters that the company invested 171 million yuan of 8 13 tons of waste heat boiler and generator set, which has not only filled the gap of the waste heat generation technology of silicon iron smelting flue gas in our country, but also was completed by the company's 200 thousand tons of silicon iron smelting furnace flue gas waste heat power generation project. Tons can reduce electricity consumption by 700 kwh, and annual energy saving will be equivalent to 17 thousand tons of standard coal and 100 thousand tons of CO2 emissions.
At the same time, enterprises mainly use silica dust for recycling and recycling, of which cloth bag recycling is up to 30 thousand tons per year. Taking the cycle and developing the economic road, enterprises basically realized no exhaust gas, waste water and waste residue.
"The national ferroalloy industry has the lowest comprehensive energy consumption, the international lead" and "the first clean production enterprise in the national ferroalloy industry", and many other honors in the body of Belden Inc is a model for the development of high energy industry in Qinghai Province, and also a miniature.
Eliminating backwardness and improving industrial concentration
The only way to transform the economy and upgrade the structure is to eliminate the backward production capacity.
"Backward" easier said than done. This is not just a pile of reports in the office, it is not only a series of data increase or decrease, it is extremely heavy and extremely difficult.
Self pressurized, warrior arm. Since 12th Five-Year, Qinghai has carried out more stringent elimination standards than the state, and increased the elimination of backward production capacity. The elimination standards of key industries such as electrolytic aluminum, ferroalloy, cement and silicon carbide are all higher than the national level of the same period.
Ning Keping, deputy director of the Qinghai Provincial Economic Commission, introduced that in the three years from 2011 to 2013, the province has eliminated 72 thousand tons of electrolytic aluminum, 670 thousand tons of cement, 186 thousand tons of ferroalloy, 102 thousand and 300 tons of silicon carbide, 679 thousand and 600 tons of steel, and completed the annual elimination of backward production capacity by the state, and achieved 1 million tons of coal saving.
It is understood that the electrolytic aluminum industry in Qinghai Province, the electrolyzer below 180KA, the iron alloy industry 12500KVA heat furnace as well as the cement industry shaft kiln have been completely eliminated, and become the first province in Northwest China to say goodbye to all machine vertical kiln production lines.
At present, the 240KA and above electrolyzer in Qinghai province accounts for 85% of the total production capacity, the main equipment and control technology of the backbone enterprises are in the leading level in China, and more than half of the ore heating furnace is over 13500KVA. The first fully closed automatic ferrochrome smelting furnace and the world's first set of high temperature furnace gas cleaning system for FERROCHROMIUM SMELTING have been put into operation, and the new dry process cement production line is the total production of 15. The number of lines is 58%, of which 8 have been built or are building a pure low temperature waste heat power generation device.
After speeding up the elimination of backward production capacity, the phenomenon of "small, scattered and chaotic" in Qinghai's key industries has been improved, and industrial concentration has been significantly improved. The number of cement enterprises in the province has been reduced to 16, the top five enterprise capacity accounted for more than half of the province; the number of ferroalloy enterprises was reduced to 12, the top five of the enterprise capacity accounted for 64% of the total capacity of the province; the average size of the electrolytic aluminum enterprises reached 330 thousand tons per year, exceeding the average level of the country, and the top three enterprises accounted for 54.21% of the production capacity of the province.
Eliminate backward production capacity and make room for advanced capacity development. Now, the production capacity of the new dry cement clinker in the province has already accounted for 83.5% of the total production capacity, and the conversion rate of the electrolytic aluminum on the deep processing is 57%, and the pattern of the scale development of advanced production capacity has gradually formed.
Energy-saving transformation also plateau a blue sky
Low investment, high output, low consumption, less emission and recycling, and sustainable industrialization are the main battlefields of Qinghai's development of circular economy.
From 2011 to 2013, 157 projects were organized and implemented in Qinghai province. The provincial financial arrangement and the national energy saving incentive fund were 275 million yuan, and the investment in energy saving technology reform was 8 billion 700 million yuan, and the annual energy saving of 1 million 720 thousand tons of coal was expected. 68 million 250 thousand yuan is allocated to support ferroalloy and cement, and the total capacity of the waste heat generating set is planned to be 128MW. After completion, the annual electricity output will be 830 million kwh.
At present, among the 25 silicon based iron alloy enterprises in the province, 3 households in Qinghai, Huacheng, Qinghai, and Tian Li have completed the construction of the waste heat power generation project and are being put into operation; other enterprises are carrying out the main equipment order and civil engineering construction, and the foundation of some enterprise power plants is close to the completion of the work. In addition, 8 of the 12 new dry cement enterprises have completed or close to completion of the waste heat power generation and utilization projects, accounting for more than 80% of the existing large-scale new dry cement production lines in the province.
Qinghai Danfeng abrasive tools Co., Ltd. and other backbone enterprises in cooperation with domestic environmental protection research institutions, carried out the research and development of the mobile smoke collecting cover project. After the related technology is ripe, the recovery rate of smoke will reach more than 50%.
Since 12th Five-Year, the energy consumption and emission indexes of the dominant enterprises have reached or close to the domestic advanced level by eliminating backward production capacity and guiding the enterprises to fully implement the technological transformation of energy saving and emission reduction. The technology of closed chrome iron furnace and smelting waste gas recovery and utilization can be attacked and put into operation. The waste heat generation technology of ferrosilicon and cement is popularized and implemented in the whole industry, which plays an important role in the task of saving energy and reducing consumption in the whole province.
Structural adjustment and industrial upgrading
"12th Five-Year" is the key period for the accelerated development of Qinghai's economy and the accelerated transformation of the industry. As the state further increases the intensity of the energy consumption and the total index of the region, the pressure on the constraints of the industrial resources and environment in Qinghai is becoming more and more intense. With the deepening of the elimination of backward production capacity and energy saving reform, the energy saving space is gradually reduced, and how to further develop the technical transformation, eliminate the backward production capacity and the important role of the adjustment structure and the transformation, and become another "climbing point" in Qinghai.
In this regard, Ning Keping, deputy director of the Qinghai Provincial Economic Commission, said that it is to optimize the stock of the stock, through the upgrading of the technological transformation of the stock, the upgrading of the industry by structural adjustment, the promotion of industrial upgrading with standard standards, and the backward elimination by the contribution rate of industrial economic growth.
It is understood that Qinghai province will combine the implementation of the five industries, such as electrolytic aluminum, iron alloy, cement and other industries, to accelerate the elimination of a number of traditional industries with small scale, high energy consumption, heavy pollution and small proportion in the industrial economy of the province.
At the same time, we should actively promote the integration of upstream and downstream industries. The cooperation and merger and reorganization between the upstream raw aluminum enterprises and the downstream processing enterprises should be promoted, and the integrated operation mode of smelting processing and application is encouraged to further improve the conversion rate of raw aluminum in local processing. We will continue to carry out the upstream and downstream docking activities of steel, photovoltaic, equipment manufacturing and other industries, and encourage the enterprises in the province to purchase local products and achieve mutual benefit with the same price and the same service.
In addition, it is closely related to the goal of single consumption, quality and pollutant discharge of the key industrial products of the province to reach or exceed the domestic advanced level, and cooperate with the environmental protection, safety supervision, quality supervision, energy and other departments, and constantly improve the standard of energy consumption limit, pollutant discharge and cleaner production of the unit products, and gradually give the enterprises and production equipment of excess energy consumption, poor environmental treatment and safety production. To eliminate it.
