LNG energy comprehensive utilization system

Abstract

The invention provides an LNG energy comprehensive utilization system which comprises a cold recovery system, a distribution type energy system, an ice storage air-conditioner system, a water collector, a water segregator, and air-conditioner tail end equipment. The cold recovery system and the ice storage air-conditioner system are connected with the ice storage device through cold recovery equipment. The distribution type energy system is connected with the cold recovery system. The ice storage air-conditioner system is connected with the distribution type energy system through the water collector and the water segregator. The efficient LNG energy comprehensive utilization system is formed through the organic combination of LNG gasification equipment and the cold recovery equipment, the organic combination of natural gas generation equipment and waste heat recovery equipment, and the organic combination of the ice storage device and the air-conditioner equipment, and the gradient utilization and the comprehensive utilization of energy are realized. The LNG energy comprehensive utilization system uses LNG as a source, only emits little low-temperature smoke finally, greatly reduces carbon emission amount and heat emission amount, and greatly improves comprehensive energy utilization efficiency.

Description

technical field [0001] The invention relates to cold recovery, distributed energy, and ice storage air-conditioning systems, in particular to a system for comprehensive utilization of LNG energy. Background technique [0002] LNG is a low-temperature liquid mixture at -162°C. When gasified per ton of LNG, it can generate about 230kWh of cold energy. Reasonable use of this part of cold energy can produce considerable economic benefits. There are more and more applications for building distributed energy stations with natural gas as energy to provide power generation, cooling, and heating. However, due to the asynchronous nature of power demand, cooling demand, and heating demand, the energy utilization efficiency of distributed energy stations is limited. . In addition, the conventional ice-storage air-conditioning system uses low-cost electricity at night to store ice, and during the day when the air-conditioning load peaks, it melts the ice for cooling to reduce the power ...

Problems solved by technology

There are more and more applications for building distributed energy stations with natural gas as energy to provide power generation, cooling, and heating. However, due to the asynchronous nature of power demand, cooling demand, and heating demand, the energy utilization efficiency of distributed energy stations is limited.

In addition, the conventional ice-storage air-conditioning system uses low-cost electricity at night to store ice, and during the day when the air-conditioning load peaks, it melts the ice for cooling to reduce the power consumption at peak loads. The power consumption of the ice storage system does not decrease but increases

At present, there is no comprehensive energy utilization system that integrates cold energy recovery, distributed energy supply and ice storage air conditioning
