Frequency Converted Energy-saving Technology
Power consumption of various motors accounts for 60% of the total power consumption in industrial enterprises, so the advanced motor energy-saving technology is of great significance to reduce the energy consumption of industrial enterprises. One of the main ways of motor energy saving is to use frequency conversion technology. By changing the motor speed, it can control the fan air flow or pump flow to meet the needs of the production process, so that the operating power will be in the best state. This technology can eliminate the energy loss of the original use of damper baffle or valve regulation. The power-saving rate of frequency conversion energy-saving technology is averagely more than 20%, maximum up to 55%. The system equipment has the advantages of high power-saving rate, long service life of electrical equipment, stable quality, less investment and quick effect.
Smelting exhaust gas power generation technology
In the process of metal smelting, such as blast furnace, rotary furnace, electric arc furnace and so on, a large amount of gas is produced in exhaust, so on-site free emission is adopted in earlier time. In order to respond to national policy of energy conservation and emission reduction, and effectively use the precious secondary resources, use this part of gas for power generation can not only effectively reduce the damage of gas emission to environment, achieve clean production of energy conservation and emission reduction, but also increase stability of the power supply, reduce production costs and improve competitiveness.
Waste Heat Recovery Technology
Medium and high temperature waste heat
The waste heat boiler uses medium and high temperature flue gas to convert water in boiler into steam. When the steam accumulates to a certain temperature and pressure, it starts to be discharged and enters the water supply system. The cold water in the water supply system is heated to hot water for use by the production department or residents.
Low temperature waste heat
Heat pump technology is the main technology used in the recovery of low-temperature waste heat, and lithium bromide absorption heat pump is the typical equipment. Absorption heat pump can be divided into two types according to different heat sources. One is Heating Type heat pump, the other is Temperature-Boost Heat Pumps.
