What are the top eight common industrial equipment power consumption?

In the industrial field, which industrial equipment consumes more electricity? Let’s take a look at the list in this article!

1. Electric Arc Furnace

An electric arc furnace is an industrial furnace that uses the heat generated by an electric arc to melt ores and metals. An electric arc is generated between the electrode and the charge to melt the metal. When the gas discharges to form an arc, the energy is very concentrated, and the temperature in the arc zone is above 3000°C. For melting metal, the electric arc furnace has greater process flexibility than other steelmaking furnaces, can effectively remove impurities such as phosphorus, the furnace temperature is easy to control, and the equipment occupies a small area, making it suitable for the melting of high-quality alloy steel.

2. Large-scale electrolytic aluminum equipment

The electrolytic cell is the key equipment for electrolytic reaction in large-scale electrolytic aluminum equipment. During the production of electrolytic aluminum, the raw materials are placed in it and a strong direct current is passed through. Under the action of the current, alumina is decomposed into aluminum and oxygen, and aluminum is precipitated at the cathode to form liquid aluminum. During the entire production process, the temperature, current, voltage and other parameters of the electrolytic cell need to be strictly controlled to ensure the quality and output of electrolytic aluminum.

3. Cement kiln

Cement kiln is mainly used to calcine cement clinker. It is a type of rotary calcining kiln (commonly known as rotary kiln) and belongs to the category of building materials equipment. It has the advantages of high temperature, alkalinity, and a complete and powerful tail gas treatment system. Compared with traditional hazardous waste incineration projects, it has the advantages of low investment and large disposal volume. The disposal scale of a single cement kiln coordinated hazardous waste disposal project is about 5-10 times that of a traditional hazardous waste incineration disposal project. The investment amount of the same scale is only about 1/3 of that of a traditional hazardous waste incineration project, and the input-output ratio is about 15-30 times that of a traditional hazardous waste incineration disposal project.

4. Air compressor

An air compressor is a device that compresses gas, similar to a water pump. Only 10% of the electricity consumed by the air compressor is converted into compressed air, and the remaining 90% is converted into heat energy. In most factories, the air compressor station pipe network has holes, aging, or loose seals, which lead to compressed gas leakage. Common leakage points include pipes, joints, flanges, hoses, drain valves, branch pipes, etc.

5. Pump equipment (large industrial pumps)

A pump is a mechanical device used to transport liquids or increase liquid pressure. It drives the impeller to rotate through a prime mover (such as an electric motor, diesel engine, etc.), causing the liquid to generate centrifugal force or pressure energy under the action of the impeller, thereby achieving liquid transportation or pressurization.

6. Fan (large industrial fan)

The large wind turbine converter products adopt three-phase voltage type AC-DC-AC bidirectional converter technology, and the core control adopts a fully digital controller with dual DSP with fast floating point computing capability. The stator magnetic field oriented vector control strategy is implemented in the rotor side converter of the generator.

7. Small processing machine tools (such as ordinary lathes, milling machines, etc.)

Common in small machinery processing plants, this type of processing machine is generally used to process mechanical parts. For example, lathes can turn rotating surfaces; milling machines can mill planes, grooves, etc.; planers are used to plan planes and forming surfaces; drilling machines can perform drilling operations, etc. Small machinery processing plants usually have a staff size of less than 30 people and an area of ​​less than 500 square meters. These small machine tools are important equipment in their workshops and can produce mechanical parts according to local conditions.

8. Small heating furnace (such as small metal heat treatment furnace)

It is suitable for petrochemical refinery research institutes (institutes), oil refining production units, atmospheric and vacuum distillation, catalytic cracking, hydrocracking, delayed coking, catalytic reforming, aromatic separation, hydrofining, alkylation, gas fractionation, asphalt, hydrogen production, desulfurization, sulfur production, etc. Some refineries also have oil pipe heating devices such as solvent deasphalting, solvent dewaxing, paraffin molding, solvent refining, lubricating oil hydrofining and clay refining. The SH-RL type laboratory electric heating furnace belongs to this category and can be used for hydrogenation, cracking coking reaction units and oil pipe heating, etc.
