Description
Technical Field
The invention relates to a production method and a device thereof, in particular to a method for energy storage production coupled with an air separation device and a device thereof, belonging to the field of air separation devices.
Background
With the development of the power structure of China towards green and low-carbon, the proportion of the installed capacity of non-fossil energy power generation such as wind, photoelectricity and the like is continuously improved. Because the supply of new energy such as wind, photoelectricity and the like is limited by natural conditions, active variable load production cannot be realized, and higher requirements are put forward on the consumption capability of a power grid. In order to reduce power grid fluctuation caused by time-space unevenness of generated energy and power consumption and improve the stability of a power grid, time-of-use electricity price policies are vigorously carried out in various places, and electric power price difference in peak-valley periods is continuously expanded.
The air separation device is an energy-consumption intensive production device which mainly consumes electric energy and produces industrial gases such as oxygen, nitrogen and the like on a large scale. The air separation device has certain variable load production capacity, and if the peak-to-peak production can be carried out by utilizing the time-of-use electricity price, the low-load production is carried out when the electricity price is high, and the high-load production is carried out when the electricity price is low, so that the production electricity cost can be greatly reduced. However, the air supply load of the air separation plant is restricted by the production requirements of downstream users, so that the production load of the air separation plant cannot be adjusted at will.
In addition to the characteristic of high transmission speed, electricity is the most important factor to be limited to the non-mass storage property. Electricity is storable, but not storable in large quantities. Because the storage equipment is necessarily very expensive if the storage equipment is stored in a large amount, the most obvious example is that the storage battery is very heavy, the stored electric quantity is limited, and if the storage battery is stored with more than one electric quantity generated by a power plant, huge resources are wasted, so that the production and the transmission of the electricity are required to be carried out simultaneously. However, the electricity generated by the power plant is usually planned in advance, is not changed at any time, is not constant, is changed and is short, and generally, the electricity is more used in the daytime and less used at night, so that the electricity generated at night is more than the electricity used, and a large amount of electricity is lost on a circuit or various power generation and transmission equipment, thereby causing resource waste.
