Embodiment Construction

[0044] The present invention includes but is not limited to the following examples. The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0045] see figure 1 Describe the system of the present invention, which includes: a gas storage tank group 1 for storing compressed gas, a gas expander 2 for expanding and depressurizing the compressed gas from the gas storage tank group 1, an air compressor 3, and the air compressor 3 is compressed by The gas is driven by the mechanical energy generated by the expansion and decompression of the gas in the gas expander 2. Specifically, in figure 1 As can be seen in the figure, the system of the present invention includes a mechanical energy transmission rod 15, which is connected between the air compressor 3 and the gas expander 2, so as to transmit the work done by the expansion and decompression of the compressed gas to the air compressor 3 as a driving force...

Abstract

The invention provides an engine matching system based on compressed gas, which comprises a gas storage tank set (1) used for storing the compressed gas and provided with a gas storage outlet, a gas expander (2) used for expansion depressurization to the compressed gas in the gas storage tankset and provided with an expansion depressurization outlet and an expansion depressurization inlet communicated with the gas storage outlet, an air compressor (3), and a mechanical energy transmission rod (15) for transmitting driving force to the air compressor (3); work produced in the expansion depressurization to the compressed gas serves as the driving force; and the mechanical energy transmission rod is connected between the air compressor (3) and the gas expander (2). The energy matching system has higher energy utilizaiton efficiency.

Description

technical field [0001] The invention relates to an energy matching system based on compressed gas. Background technique [0002] At present, the energy utilization rate of the traditional process of high-pressure gas (such as CNG-compressed natural gas) station is low, and in the process of compressed gas transmission, additional cooling or heating energy needs to be provided, which further reduces energy efficiency. The present invention aims at the above problems, and according to the principles of thermodynamic laws, comprehensively utilizes the cooling loss in the process to achieve the purpose of heat and work recovery, and finally improves the comprehensive utilization efficiency of the gasification station. At the same time, the invention provides a system solution for joint multi-energy supply. [0003] The prior art solutions generally use high-pressure gas (such as CNG) to directly decompress and expand to obtain low-pressure or normal-pressure gas (such as NG). ...
