Enterprise energy saving and emission reduction measures?

Energy conservation and emission reduction are actually two categories, one is energy conservation and the other is emission reduction, which are related but different.

Let me answer from my understanding of the conservation of energy:

Enterprise energy saving, I think you are a company in Guangdong, so it is estimated that the main energy consumption is electricity.

Therefore, to save energy, we must start with saving electricity.

As we know, the power consumption of enterprises generally accounts for the third place in the cost of enterprises. Reducing the cost of electricity and electricity will reduce the production cost and directly help enterprises improve the competitiveness of their products!

However, due to the lack of acceptance and understanding of energy-saving related knowledge, enterprises often choose a technical transformation method directly when faced with energy-saving pressure. Often this technical transformation will bring risks to future energy-saving achievements because there is no data support and verification. It is also difficult to accurately evaluate and measure the effect of energy saving.

We all know that all improvement processes are nothing more than understanding data, mastering data, analyzing data, evaluating risks and implementing them.

Energy saving is no exception.

At present, 90% of enterprises do not know how much they spent this month until they pay the electricity bill every month. There is no accurate data like other management of enterprises (production management, supply management, administrative management).

Therefore, 90% of enterprises are still in a state of blindness and disorder in power consumption management, which often does not match with other management levels of enterprises. In this way, although the energy cost is a relatively large production cost, it has become a shortcoming of enterprise development.

If enterprises attach importance to electricity consumption and electricity consumption as a limited resource and production cost, they must put electricity consumption management and production management at the same level.

Just like seeing a doctor, to solve the patient's illness, it is necessary to comprehensively analyze the condition and etiology in order to achieve accurate treatment. Headache can't be cured, foot pain can't be cured.

The first step for enterprises to start energy-saving measures is measurement and statistics.

1, enterprises must establish an accurate measurement system, accurate statistics of power consumption.

In order to make the improvement of enterprises more effective, we can start with production equipment with high power consumption, production equipment that is difficult to control and production equipment that is not in place. At present, many enterprises are aware of the importance of econometric statistics, but the methods adopted are not very scientific, and they often adopt relatively backward manual meter reading methods. The disadvantage of manual meter reading is that the data collected is incomplete and discontinuous, and it is impossible to accurately grasp the dynamic energy consumption curve of equipment in production state. Such data has certain value for enterprises, but the value of analysis is too small. What we need is complete, dynamic and real-time electricity consumption data of production equipment, and we also need relevant analysis AIDS to help us analyze and diagnose. Therefore, this first step is quite critical and important, and it is the basis of energy-saving measures.

The second step of enterprise energy saving measures: analysis

1. After measuring and counting the electricity consumption data, the enterprise needs to carry out relevant analysis, such as:

Is there direct waste, and is the off-duty equipment accurately operated according to the rules and regulations and switched on and off on time?

Is there too much equipment in the production process in an unnecessary idle state?

Do employees give priority to the use of energy-efficient production equipment?

Which equipment is inefficient and needs corresponding technical improvement?

Is the distribution capacity of enterprises reasonable, and is there any waste of "big horse-drawn carts"?

Wait, wait, wait

Only by mastering the details can we analyze it accurately.

The third step of enterprise energy saving measures: improvement

After we accurately analyze the power consumption of enterprises, we can start to improve from the following two aspects:

1. Strengthen management and reduce direct waste.

According to the results of the analysis, implement a sound power management system and use objective data to strengthen the execution of employees. There are also many enterprises with perfect management systems, but there are still many cases of waste. What is the reason? The management system that lies in implementation but cannot be implemented is just a dead letter with no result. Therefore, if enterprises use some auxiliary monitoring tools to implement management, they can help enterprises grasp the effect of employees' implementation in real time and be accountable afterwards! There are many professional companies whose energy management systems can provide perfect data measurement and statistics, as well as real-time monitoring functions. With these tools, our enterprise's energy management measures and energy-saving improvement management measures will be better implemented, and the energy-saving effect will be more obvious.

2. Technical transformation.

According to the data analysis of equipment energy efficiency, some equipment with low energy efficiency is reformed accordingly. For example, the frequency conversion and servo transformation of large motors can greatly improve the production efficiency of equipment and recover the investment soon. Generally, there are some measures with mature technology, low cost and obvious effect:

Air compressor waste heat utilization, frequency conversion transformation, comprehensive intelligent centralized control

Servo reform of injection molding machine, frequency conversion reform of injection molding machine

On-site reactive power compensation and centralized reactive power compensation of motor

Harmonic control

Intelligent control of central air conditioning.

The technology of technological transformation has been tested by the market, and it is no longer a concept. Many energy-saving enterprises have introduced technical transformation technology from a strategic perspective and implemented relevant measures. It has brought many practical effects to enterprises. In the case of rising labor costs, reducing production costs starts with energy management and energy saving, so that enterprises have more advantages in competition. The so-called strong will always be strong, which is the truth.

The above is my personal answer, hoping to attract more experts to participate in the answer!
