Industrial thermal emission heat recovery & reuse system

　　Industrial thermal emission heat recovery&reuse system
　　There are many drying equipment is often used to raise the air(fresh air)to a certain temperature and process the materials.Such as,food,chemical,pharmaceutical,electronics,spraying,printing,paper,chemical fiber and other industries.However,the used air is discharged as exhaust gas(exhaust air),and the exhaust gas is usually high in temperature and directly discharged into the atmosphere,which will cause a lot of energy waste.
　　Drying case
　　For example,assuming a place with an annual average temperature of 10°C,a drying system air volume of 10000m3/h,and a drying process temperature of 80°C,it is necessary to provide about 235kW of heat to the drying box by means of electric or steam heating.The process is as follows,if the exhaust gas is directly discharged,the 235 kW of heat heated by electric or steam is will discharged into atmosphere,resulting in a waste of energy.

　　In the exhaust gas emission system,adding a heat exchange box that can realize the waste heat recovery.
　　The main component of the heat exchange box is the BXB plate heat exchanger.The plate heat exchanger is mainly made of aluminum foil(or stainless steel foil).When there is a temperature difference between two airflows that are isolated by aluminum foil and flow in opposite directions,heat transfer will occur to realize energy recovery.Through the BXB air sensible heat exchanger,the conversion in the exhaust air can be used to preheat the fresh air.As the result,it will achieve the purpose of energy saving.

Purify air conditioning fresh air system

Medical treatment, biopharmaceutical and high-end electronic intelligence industries have emerged as the country's large-scale industrial strategy, and these industries cannot be separated from the application of purification systems. Because of the particularity of the purification system, the introduction of fresh air and the discharge of some indoor air are realized by power, so the demand for energy is fixed. In the system without new and exhaust energy recovery devices, fresh air will consume a lot of energy, while the energy in exhaust air will be wasted. If the energy in exhaust air can be recovered and the fresh air can be pre-cooled or preheated, the waste of resources can be reduced to the maximum extent. The system mode of strong delivery and strong exhaust is more conducive to the arrangement and utilization of new and exhaust energy recovery.

In the air conditioning system design of major hospitals, treatment centers and animal laboratories, in order to avoid cross pollution, the distance between new fans and exhaust fans is usually relatively far. Our company can provide liquid circulating energy recovery scheme. This energy recovery method can effectively avoid cross-contamination of fresh and exhaust air, effectively recover the cold heat in exhaust air through liquid circulation, and release the recovered energy into fresh air, so as to achieve the purpose of reducing energy consumption of fresh air. This recovery system can drag one or more modes.

Wind Generator Air to Air Indirect Cooling System

Wind power system background

Wind power is a kind of clean energy, with the characteristics of renewable, pollution-free, large energy and broad prospects. The development of clean energy is the strategic choice of all countries in the world.

However, if the air is directly fed into the generator cabin for cooling, the dust and corrosive gas will be brought into the cabin (Especially wind turbines installed offshore).

Indirect cooling system solution

The indirect cooling method can make the air from inside and outside perform indirect heat exchange to achieve the effect of cooling the wind generator cabin without bringing dust and corrosive gases from outside into the cabin.

The main component of the indirect cooling system is the BXB plate heat exchanger. In the BXB plate heat exchanger, two channels are separated by aluminum foil. The air in the cabin is closed circulation, and the outside air is open circulation. The two airs are doing heat exchange. The air in the cabin transfers heat to the outside air, which reduces the temperature in the wind generator. In addition, the air inside and outside the cabin will not be mixed due to the isolation of aluminum foil, which prevents dust and corrosive gases outside the cabin from being brought into the cabin.

Cooling effect analysis

Taking a 2MW unit as an example, the motor's heat generation is 70kW, The circulating air volume in the engine room is 7000m3/h and the temperature is 85℃. The outside circulating air volume is 14000m3/h and the temperature is 40℃. Through the BXB1000-1000 plate heat exchanger, the air temperature in the cabin can be reduced to 47℃ and the heat dissipation capacity can reach 72kW. The relevant parameters are as follows:
