Abstract

The invention relates to a CNG and HCNG mixing and refilling device and a CNG and HCNG mixing and refilling method. The device comprises a prepositioned treatment system, a mixing and pressurizing system and a filling and storing system, wherein the prepositioned treatment system is connected with the filling and storing system by the mixing and pressurizing system; the prepositioned treatment system comprises a pipe bundle CNG conveying trailer, a pipe bundle hydrogen gas conveying trailer, a CNG unloading column, a hydrogen gas unloading column, a CNG purifier and a hydrogen gas purifier; the mixing and pressurizing system comprises a mixing device, a CNG special piston compressor set and an HCNG special diaphragm compressor set; a gas inlet of the CNG special piston compressor set is connected with a gas outlet of the CNG purifier; the gas outlet of the CNG special piston compressor set is connected with the filling and storing system; a hydrogen gas inlet pipeline of the mixing device is connected with the gas outlet of the hydrogen gas purifier; a CNG inlet pipeline is connected with the gas outlet of the CNG purifier; an HCNG outlet pipeline is connected with the gas inlet of the HCNG special diaphragm compressor set; and the gas outlet of the HCNG special diaphragm compressor set is connected with the filling and storing system. The CNG and HCNG mixing and refilling device and the CNG and HCNG mixing and refilling method can be widely applied to gas stations of HCNG cars and CNG cars.

Description

Technical field [0001] The invention relates to a gas filling device and a gas filling method, in particular to a CNG (compressed natural gas) and HCNG (compressed natural gas mixed with hydrogen) mixed gas filling device and a gas filling method. Background technique [0002] HCNG is a gas fuel mixed with natural gas with methane as the main component and hydrogen with purity greater than 99%. The mixing ratio is to add hydrogen with an energy percentage of 5% to 20% (volume percentage of 15% to 60%) in natural gas. . [0003] HCNG has the advantages of natural gas and hydrogen. After natural gas is burned, there is no waste residue and waste water. It is safe to use and has high calorific value. Hydrogen has the characteristics of wide ignition range and fast flame propagation. The hydrogen-mixed compressed natural gas can achieve lean combustion of the engine, reduce engine emissions, improve engine thermal efficiency, and ensure engine power. It is an ideal low-carbon, green e...
