Cold chain logistics park integration system based on LNG energy cascade utilization

Abstract

The invention relates to a cold chain logistics park integration system based on LNG energy cascade utilization. The system comprises an LNG cold energy three-stage utilization subsystem, a natural gas cold-heat-power triple-supply multi-energy coupling subsystem and a refrigeration subsystem, wherein the LNG cold energy three-stage utilization subsystem, the natural gas cold-heat-power triple-supply multi-energy coupling subsystem and the refrigeration subsystem are mutually connected; the LNG cold energy three-stage utilization subsystem is correspondingly connected with a gas internal combustion engine unit and an expansion generator unit respectively through a first gasifier and a heater; the first gasifier and the heater are arranged in the LNG cold energy three-stage utilization subsystem; the gas internal combustion engine unit and the expansion generator unit are arranged on the natural gas cold-heat-power triple-supply multi-energy coupling subsystem; the refrigeration subsystem is correspondingly connected with a first residual cold heat exchanger arranged in the LNG cold energy three-stage utilization subsystem and a second residual cold heat exchanger arranged in the natural gas cold-hot-power triple-supply multi-energy coupling subsystem through a throttling valve and a condenser; and the throttling valve and the condenser arranged are arranged on the refrigerationsubsystem. Compared with the prior art, the system has the advantages of high comprehensive energy utilization rate, remarkable energy saving and emission reduction and the like.

Description

technical field [0001] The invention relates to the technical field of cascaded utilization of LNG energy, in particular to a collection system of cold chain logistics parks based on cascaded utilization of LNG energy. Background technique [0002] Cold chain logistics park refers to a special supply chain system that uses low temperature conditions to ensure food quality and safety, reduce loss and prevent pollution. In particular, urban cold chain logistics parks are specialized in food processing, freezing, cold storage, food wholesale operations, food processing A large-scale comprehensive logistics park integrating exports. With the continuous development of the economy and the continuous improvement of the modern logistics system, the development prospect of cold chain logistics will be very broad, and its potential is huge. However, cold chain logistics is a large power consumer. The cold chain logistics industry has a single energy supply method and a simple energy ...
