Description

Technical Field

[0001] The invention relates to the technical field of air compressor energy saving, and in particular to a two-way energy conversion system of an air compressor station and a liquid gas station. Background Art

[0002] In modern industry, especially in heavy industries such as shipbuilding, chemical industry, smelting, heavy equipment and machinery manufacturing, compressed air, carbon dioxide, oxygen, natural gas and nitrogen are often needed in the production process. Therefore, in order to facilitate production and ensure continuous and stable production, enterprises often arrange air compressor stations and various liquid gas stations internally. When the air compressor is running, through the consumption of electric energy, on the one hand, it produces compressed air with a certain pressure required by the enterprise, and on the other hand, the air compressor generates a large amount of "compression heat" during the compression process and diffuses into the environment. This part of compression heat accounts for about 60% of the total energy consumption of the air compressor, of which 20% of the heat dissipated by the compressor unit is not easy to absorb and utilize, and the remaining about 40% is relatively easy to recycle. If this part of the waste heat is not used, it will be wasted. At the same time, the energy efficiency of the air compressor is closely related to the cooling water and ambient temperature. For every 10°C increase in cooling water or ambient temperature, the energy efficiency of the air compressor will decrease by 5-10%. In addition, if the air compressor is not well cooled during operation in summer, it will not only reduce the energy efficiency of the air compressor, but also easily cause high-temperature shutdown accidents, thus affecting the continuity of the company's production. Therefore, improving the cooling effect of the air compressor is very important for the air compressor.

[0003] At the same time, in the production and manufacturing process of modern enterprises, it is often necessary to cut and weld metal materials, which requires gases such as carbon dioxide, oxygen, natural gas, and nitrogen. Liquid gas must be vaporized by a vaporizer to turn liquid gas into gaseous gas, and maintain a certain temperature before it can be used. Liquid gas is often vaporized by an air vaporizer. The air vaporizer relies on the atmosphere of the surrounding environment to heat the vaporizer. The vaporization process of liquid gas is a "heat absorption-cooling" process. In summer, the temperature is high, and the air vaporization vaporizer has good effect and high efficiency, but in low-temperature weather, the vaporization efficiency of the air vaporizer becomes low. If there is no electric heating to assist vaporization, the vaporization temperature is often below 0℃. At the same time, for every 1℃ increase in gas temperature, the volume increases by 0.3%. If the vaporization temperature of liquid gas is increased to 25℃, the vaporization volume of liquid gas can be increased by at least 5%, which is difficult to achieve with conventional air temperature vaporizers (except in summer). Therefore, it is very important to find an energy-saving, safe, and environmentally friendly method to improve the vaporization efficiency and vaporization quality of liquid gas station vaporizers. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a two-way energy conversion system for an air compressor station and a liquid gas station, which uses "circulating water" to transport the heat generated by the air compressor to the vaporizer of the liquid gas station to heat the vaporizer. Because the enthalpy value of water is higher than that of air, and water is constantly circulating, the vaporizer is heated by circulating water. The vaporization efficiency and vaporization quality of the vaporizer are much higher than the efficiency of natural heating and vaporization by air, especially in weather with relatively low temperatures. After the circulating water passes through the vaporizer, the heat is absorbed by the vaporizer and the circulating water temperature is reduced. The circulating water temperature is reduced by 8-10°C, especially in summer, it can reach or even be lower than the requirement of 32°C for air compressor cooling water. The water temperature of the cooling fan of the air compressor cooling water tower is reduced by 2-6°C (depending on the temperature), and the fan consumes electricity. Therefore, the effect of the vaporizer cooling water is better than the cooling effect of the cooling fan, and it does not consume electricity. And the cooling water cooled by the vaporizer directly enters the air compressor to cool the air compressor, which not only improves the cooling effect of the air compressor, but also improves the energy efficiency of the air compressor.
