Skid-mounted compressed natural gas vehicle filling device

Abstract

The invention discloses a skid-mounted compressed natural gas automobile air-entrapping device which comprises an air discharging column, a compressor, an air cylinder group, an air-entrapping machine, a skid-mounted body and a base, wherein an air source inlet, a medium-pressure air source inlet and a low-pressure air source inlet are formed in the base; the air source inlet is connected with the air discharging column; the air discharging column is respectively in pipeline connection with the compressor and the air cylinder group; a manual stop valve is arranged on a pipeline between the air discharging column and the compressor; the compressor is connected with the air cylinder group; the air cylinder group, the medium-pressure air source inlet and the low-pressure air source inlet are respectively connected with an air inlet of the air-entrapping machine; the air discharging column, the compressor, the air cylinder group and the air-entrapping machine are arranged on the base and are positioned in the same skid-mounted body. According to the skid-mounted compressed natural gas automobile air-entrapping device, the operations of air discharging, compressing, controlling, air storing and air entrapping are integrated, the device is small in floor space and convenient to move and use, the approval process can be finished at a time, and the device can be used as fast as possible and is particularly suitable for vehicle air-entrapping in departments such as bus stations, driving schools and taxi enterprises.

Description

technical field [0001] The invention relates to a compressed natural gas vehicle (CNGV) gas filling device, in particular to a skid-mounted compressed natural gas vehicle gas filling device used in conjunction with a natural gas transport bottle car. Background technique [0002] With the deepening of reform and opening up, the development of the national economy, the increasing popularity of mechanization, and the increasing improvement of people's lives, urban buses, taxis, and private cars are increasing day by day. The emissions from automobiles seriously pollute the atmosphere on which human beings depend, making the environment overwhelmed. Especially in recent years, domestic smog weather has become more and more serious on the national economy, and the control of air pollution has received much attention from governments around the world. [0003] The main component of natural gas is methane (CH 4 ), compared with fuel oil, the calorific value of natural gas per un...

Problems solved by technology

However, due to the large area and the large number of vehicles, the gas filling stations planned by the government are far from meeting the needs. There are thousands of gas filling stations in every province waiting for investment and construction

[0005] However, the construction of compressed natural gas vehicle (CNGV) refueling sub-stations covers a large area, and the approval procedures involve many management departments: government planning, safety, fire protection, industrial and commercial approvals are required; model selection, procurement, refueling station design, installation, Commissioning, acceptance, business license, etc., the procedures are quite complicated and the cycle is long, which seriously affects the promotion and use of natural gas
