Description

An industrial wind power recovery system

technical field

The invention relates to a device for collecting industrial exhaust air and using it for power generation, in particular to a system for generating electricity by using industrial exhaust air.

Background technique

In recent years, refrigeration technology has radiated to all aspects of people's daily life and has been widely used in various fields. According to the second law of thermodynamics, it can be seen that the energy consumption of refrigeration should not be underestimated. Statistics show that the major energy-consuming household in buildings is the refrigeration system, which accounts for 25% to 30% of the total energy consumption of buildings, and the energy consumption of building operation accounts for about 30% of the total energy consumption of the whole society. In countries such as Europe and the United States, the annual energy consumption of central air-conditioning systems accounts for about 50% of the total energy consumption of buildings; in Middle Eastern countries, where the climate is relatively harsh, the electricity required for cooling accounts for about 60% of the daily electricity consumption of residents. It is not difficult to see that the current trend of the total electricity consumption of domestic refrigeration systems and its proportion in the total energy consumption of buildings is rising rapidly. As the main energy source of human beings, petrochemical energy is non-renewable. To some extent, the depletion of petrochemical energy leads to an inevitable rise in energy prices, which also highlights the important position of energy-saving indicators in the competition of engineering equipment. Therefore, it has become an important topic in the refrigeration and air-conditioning industry to actively recycle the secondary energy that is generated in the refrigeration system and will be wasted. This is not only of great significance to saving energy and improving the efficiency of refrigeration equipment, but also plays an important role in the process of protecting the ecological environment.

The condenser is one of the core equipment of the refrigeration system. Among them, the air-cooled condenser, the evaporative condenser, and the cooling water tower are all equipped with fans. These fans will inevitably generate wind energy while taking away the heat released by the refrigerant. , if this part of wind energy is not utilized, it will be a huge waste, and the exhaust of the central air conditioner also has this type of problem.

Contents of the invention

Aiming at the problem that the wind energy in the industrial exhaust air cannot be fully utilized and is wasted in vain, the invention proposes a system for generating electricity by recycling the industrial exhaust air.

An industrial exhaust wind electric energy recovery system, the system is composed of an industrial exhaust air recovery system and a wind power generation system; the wind energy recovery is composed of an exhaust outlet of an industrial exhaust equipment connected to an exhaust recovery air duct; the wind power generation system Including the wind generator, the charge controller of the wind generator and the battery connected in sequence, the battery is respectively connected to the inverter and the DC electrical appliance, and the inverter is connected to the AC electrical appliance; the end of the exhaust air recovery duct is adjacent to the blades of the wind turbine set up.

The end of the exhaust air recovery duct is provided with a square bell mouth, so that the collected exhaust air can be evenly blown on the blades of the wind power generator.

The industrial exhaust equipment is an air-cooled condenser, an evaporative condenser cooling tower or a central air conditioner.

The present invention has the following technical effects:

1. This system uses recycled air-cooled condensers, evaporative condensers, cooling towers and central air-conditioning exhaust outlets to generate electricity. Compared with other power generation systems, it saves energy and is environmentally friendly and pollution-free.

As shown in Figure 1 and Figure 2, an industrial exhaust wind power recovery system, the system is composed of an industrial exhaust wind recovery system and a wind power generation system; The recovery air duct 2 is composed; the wind power generation system includes a wind power generator 3, a wind power generator charging controller 4 and a storage battery 5 connected in sequence, the storage battery is respectively connected to the inverter 6 and the DC electrical appliance, and the inverter is connected to the AC electrical appliance 7. The end of the exhaust air recovery duct is set adjacent to the blades of the wind power generator.

The industrial exhaust equipment is an air-cooled condenser, an evaporative condenser cooling tower or a central air conditioner.

The end of the exhaust air recovery duct is provided with a square bell mouth, so that the collected exhaust air can be evenly blown on the blades of the wind power generator.

The exhaust air recovery duct can collect various industrial exhaust air such as cooling towers, evaporative condensers, air-cooled condensers, central air conditioners, etc. It is applicable to a wide range of fields and can make full use of industrial exhaust air to avoid waste.
