With rapid economic growth and increasing population, efforts to alleviate the contradiction of insufficient resources, continuous improvement of the ecological environment, and sustainable development, various environmental protection and energy conservation policies and measures have become our familiar development trend of civilized life. Everything we eat, eat, live, and produce depends on this earth. To advocate energy conservation and environmental protection, we must first understand the energy consumption in our daily life. Where is the pollution? Focus on major issues to improve energy efficiency and environmental efficiency. These include household pollution and social pollution.

 

 

Recent studies have shown that for social pollution, the pollution caused by social industrial production has accounted for 41% of the pollution source. Industrial production can be divided into three categories: one is textile industry accounting for 30.2%, the first is resource processing industry accounting for 30.2%, and the other is mechanical and electronic manufacturing accounting for 35.5%. Nowadays, there are energy-saving equipment in many industries, the main purpose is to save energy and protect the environment, and it can save costs for enterprises. Among them, industrial electric furnaces are widely used in industrial, mining, metal, ceramics, glass, powder metallurgy, optoelectronics, pharmaceuticals, automobiles, etc., heating, heat treatment and sintering of various large and medium-sized electric furnaces, the common feature is the use of electrothermal effect heat. Therefore, the development of energy-saving green environmentally friendly industrial electric furnace has become the main trend.

 

The electric furnace is a heating furnace that converts the electric energy in the furnace into heat to heat the workpiece. Compared with the fuel furnace, the advantages of the electric furnace are: the furnace atmosphere is easy to control, and even the vacuum can be pumped; the material is heated quickly, the heating temperature is high, and the temperature is easy to control. The purpose of energy-saving transformation of industrial electric furnace is nothing more than improving the overall operating efficiency of the furnace. Energy-saving industrial electric furnace can reasonably preheat the furnace material, which can shorten the melting time and save energy and reduce consumption. Usually, the following factors should be paid attention to: 1. Improve heat exchange efficiency, which is to improve the heat exchange efficiency of the furnace tube; 2. Reduce unnecessary Losses, such as smoke loss, heat loss in the furnace body, 3. Increase the initial physical heat of the fuel or water. 4. Collect as much heat as possible to recover the smoke.

 

In the production and manufacture of energy-saving and environment-friendly industrial electric furnaces, the following requirements are put forward for the rationalization of electric furnace conversion into thermal energy:

(1) The configuration efficiency of the electric arc furnace should not be lower than 50%, and the other heating configuration efficiency should not be lower than 40%;

(2) For the electric heating configuration above 50KW, configure the voltmeter, ammeter, active energy meter and reactive energy meter;

(3) The stainless steel inner tank is used to radiate the generated heat, which is more energy-saving than the traditional brick inner tank, and the temperature in the furnace is more uniform.

 

Energy conservation and emission reduction are not only problems caused by environmental pollution caused by production and automobile exhaust emissions. As a company that uses electric furnaces, environmental protection, energy conservation and emission reduction should also be placed first. Choose energy-saving and environmentally-friendly electric furnaces to truly do a comprehensive energy-saving and environmental protection.
