Abstract

The invention discloses a compressed natural gas releasing device and a power generation method employing pressure potential. The compressed natural gas releasing device comprises a compressed natural gas heat exchange filtering device, wherein the back of the compressed natural gas heat exchange filtering device is connected with power generation device components, and the compressed natural gas heat exchange filtering device is arranged between two voltage regulators, and releases pressure in a pipeline through a releasing pipeline. The problem that compressed natural gas equipment completely depends on an electric network is solved, and the purpose that the compressed natural gas equipment can employ own compressed natural gas differential pressure for power generation is realized.

Description

technical field [0001] The invention belongs to the technical field of compressed natural gas decompression, and relates to a compressed natural gas release device, and also relates to a method for generating electricity by utilizing the pressure potential energy of compressed natural gas. Background technique [0002] With the continuous promotion of natural gas and the government's various incentive policies for clean energy, the gas equipment manufacturing industry has also developed rapidly. Since the gas pipeline network cannot be fully covered for the time being, the application of compressed natural gas is becoming more and more extensive. There are more and more compressed natural gas equipment. [0003] The use of compressed natural gas has the following disadvantages: the pressure potential energy of compressed natural gas is not utilized, resulting in a large amount of energy waste; the power supply of compressed natural gas release equipment is completely depende...
