The Development Direction Of Printing And Dyeing Energy Saving And Environmental Protection Work Has Proposed Increasing Energy Conservation And Emission Reduction Efforts.

The 2011 national printing and dyeing industry, which has been held recently.

In addition, Professor Xi Dan Li, director of environmental technology Specialized Committee of China dyeing and Printing Association, "

From the details, it is easy to find out that after the two major environmental conferences in Copenhagen and Cancun, the international pressure and power on China's energy saving situation, and what aspects of energy conservation should be started in the future, the energy saving prescriptions are put forward.

Xi Dan Li first stressed that printing and dyeing enterprises lack the right to choose energy types, so the implementation of low-carbon economy is essentially the argument of "energy conservation".

In his speech, he said that after the two major environmental conferences such as Copenhagen and Cancun, the pressure and motivation for China's energy saving situation were as follows: the energy consumption per ton of fiber in the whole industry dropped from 4.84tce in 2000 to 3.1tce in 2009, that is, the total energy consumption per ton of fiber dropped by 9.1%, supporting an average annual development of 18%.

In the 31 industrial sectors of the country, the proportion of energy consumption dropped from 4.3% in 2005 to 3.6% in 2009, indicating that the energy conservation and emission reduction work in the textile industry has been in the forefront of other industries in the country.

Information from the NDRC shows that during the "12th Five-Year" period, the government will make greater use of market mechanisms and economic means to achieve the goal of reducing carbon intensity.

Now we have explored carbon trading in Tianjin, Beijing and Shanghai. During the "12th Five-Year" period, the implementation of this measure may go faster.

Even according to the news, China will levy carbon dioxide tax in 2012.

According to ~20 yuan per tonCO210 yuan.

At present, Denmark, Finland, Holland, Norway, Sweden, Germany, the United Kingdom, Switzerland, Japan and Australia have implemented carbon tax or energy tax policy in more than 10 countries.

The United States will also levy carbon tax in July 2012.

However, the legality of carbon tariffs is still controversial in academia.

The focus is on the issue of carbon tax and carbon tariffs. The reason is that the Levy of carbon tariffs violates the free trade principle and the most favored nation treatment principle of the World Trade Organization (WTO).

China is the producer, the price side, while the developed countries are consumers, but they also want to levy taxes on us. The essence of carbon tariffs is an international political and economic issue, which has lost the significance of reducing carbon emissions.

The carbon tax is a management method of energy conservation and emission reduction within a country.

At the same time, we must clearly realize that the focus of carbon trading is the macro level, and the price has greater volatility.

We must adapt to these changes.

"Here is another mention of Greenpeace's investigation in Chinese enterprises.

There is also the national and national Ministry of environmental protection standards on the issue of increasing indicators, the key is: the harmful nature of chemicals is relative, is gradually improved, and there should be a buffer period of 3 years ~5, can not unilaterally immediately request the use of a chemical (unless extremely toxic).

Otherwise, it is actually promoting products for some European countries, and they are constantly improving according to the needs of our enterprises, thus enabling developing countries to continuously buy their high quality products.

Xi Dan Li said.

How much potential do we have to dig?

Xi Dan Li also analyzed the potential of energy saving in textile industry under various scenarios.

What is "potential"? It is the gap between the world's best technology and equipment, material consumption and energy consumption.

This includes: technology, equipment, management and so on.

According to analysis: the energy saving rate of textile industry has exceeded the national average since 2005.

On the contrary, "potential" is getting smaller and smaller.

If the purpose of energy saving 5%~8% is to be achieved every year during the "12th Five-Year" period, the energy consumption will only be 77.36% in the 5 years and 5% in 8% years, and the pressure on the textile enterprises will be greater than that in the past 5 years.

So how much potential do we have to dig? First is managing energy efficiency.

According to the state's different energy saving efforts, in the view of Xi Dan Li, the national management energy saving rate is set to be 3%~10% in 5 years.

Secondly, industrial structure and product structure adjustment and energy saving: increasing the proportion of knitted products is conducive to the reduction of overall energy consumption.

According to rough estimates, the energy saving per unit product will increase by 8%~12%, and the overall energy saving rate will be increased by 2%~6% when mixed with all products.

And technology, equipment and energy saving: This includes the gradual improvement and popularization of new technology and technology.

For example, popularizing cold rolling and pushing technology, this technology can save energy by 30%, but requires larger workshops and stable room temperature conditions.

From what aspects of energy conservation?

Xi Dan Li focused on the factors that affect the energy consumption of products. He analyzed: "the same kind of products, different grades, energy consumption is different.

A success rate and repair rate affect energy consumption.

There is also the effect of equipment operating rate. When the operating rate is less than 70%, the energy consumption is obviously improved.

The difference of management level and the difference between East and West is obvious. The advanced degree of technology and equipment will directly affect the energy consumption of products.

Taking Shaoxing as an example, after investigating more than 40 printing and dyeing enterprises, it was found that when the dyeing processing fee per meter was below 2.5 yuan, the energy consumption was 0.7tce~0.9tce and the actual displacement was 80t/t.

When the processing fee is 6 yuan ~7 yuan per meter, the energy consumption is 1.1tce~1.2tce and the actual displacement is 110t/t~120t/t.

The factors that affect energy consumption in the final analysis are: product variety knitting and weaving; management level -- software and hardware, technology and equipment.

In terms of management, the three level energy management is an inevitable trend.

On the scale of printing and dyeing enterprises -- the difficulties of big drawbacks; from the three level management of automation and energy analysis, the output is 20 tons per day (or more than 100 thousand meters).

At present, the textile industry is at the forefront of the 39 industry average level in the whole country, and the annual energy saving rate is 9.1%, supporting the development of 18%.

Finally, Xi Dan Li put out a prescription for energy saving recommendation: for example, in 2011, the total energy consumption, the total amount of wastewater discharge and the total amount of COD emissions in ~2015 were unchanged. The energy consumption and total reduction rate of unit products were 25.3% and the average annual reduction rate was 5.2%.

Similarly, in 2016 ~2020, the total reduction rate of energy consumption per unit product was 13.6%, with an average annual reduction rate of 2.8%.

Thus, the total energy consumption in 2010, 2015 and 2020 can be maintained at 79 million 460 thousand TCE.

In 2011, after ~2015 pformation, the average annual investment was 20 billion 250 million yuan, and the total cost of renovation in the 10 years was about 202 billion 500 million yuan.

If the investment in the ~2015 pformation in 2011 was calculated at 42 billion 520 million yuan a year, the investment in 2016 ~2020 will be calculated at 35 billion 640 million yuan per year, of which 30 billion yuan will be invested annually because of the increase in output and profits. The textile industry itself will be difficult to digest, and the state needs to give considerable encouragement policies, such as the deduction of a certain proportion of income tax, business tax and financial support from technological pformation. The total cost of upgrading will be 390 billion 900 million yuan in 10 years.
