Embodiment Construction
[0012] Below in conjunction with accompanying drawing and embodiment mode, the patent of the present invention is described in further detail:
[0013] The patent of the present invention specifically relates to a method and device for realizing the utilization of cold energy in liquefied natural gas satellite stations. The device includes the following three systems: refrigerant circulation system, air medium system, and rubber cryogenic crushing system.
[0014] (1) Refrigerant circulation system: This system uses the cold energy of liquefied natural gas in the LNG satellite station as the cold source, and exchanges heat with the normal temperature refrigerant in the LNG heat exchanger (1). The refrigerant after heat exchange is stored at about -130°C to In the refrigerant storage tank (2), when in use, the refrigerant pump (3) is used to transport the refrigerant to the refrigerant heat exchanger (4) to exchange heat with the air. 5) is for pre-cooling the processed materia...

The invention discloses a method and a device realizing the cold energy utilization of liquefied natural gas (LNG) satellite stations, and belongs to technical fields of oil and gas storage and transportation and transportation engineering. According to the method, LNG cold energy is utilized to freeze waste rubber, after the glass transition temperature of rubber is achieved, low-temperature grinding is performed, and refine processing of waste rubber can be satisfied. The cold energy can be transferred through refrigerants during the technical process, air is served as cryogenic processing medium, coarse rubber particles are mixed with grinding aiding coal before cryogenic processing, and the refrigerants and the grinding aiding coal are circularly used, so that the whole technical process is realized. The method has the advantages that the method is simple to operate and convenient to control, the automation degree is higher, not only is the cold energy of the LNG satellite stations is utilized, but also the refine processing of waste rubber is realized, and the requirement on the size of particles is satisfied on the premise that properties of rubber are not damaged.
Description
technical field [0001] The invention belongs to the technical field of oil and gas storage and transportation engineering, and in particular relates to a method and a device for realizing cold energy utilization of a liquefied natural gas satellite station. Background technique [0002] LNG is formed by cooling natural gas to -162°C under normal pressure to solve the problem of natural gas used by residents and industries in areas where natural gas cannot reach due to the constraints of the pipeline network. LNG is transported by ships, tankers and other tools to Designated receiving stations, satellite stations and other stations can provide users with gas after gasification and other related procedures. However, LNG will release a large amount of cold energy (about 230kw h / t) during the gasification process in the station. Most domestic receiving stations and satellite stations do not use this part of cold energy, but directly discharge it with air or seawater. into natur...
