Primary gas filling station

Abstract

A brand new primary gas station which is composed of a low-temperature cylindrical container (tank car), a low-temperature liquid-phase high-pressure pump, a carburettor, a plurality of gas storage devices, and introduces the multi-gas-storage-device concept of the auxiliary gas station, establishes the multi-gas-storage-device interchange and cycle systems for the primary and auxiliary gas stations. The plurality of gas storage devices provide huge gas storage capacity for the primary station to save the investments on the large equipment, such as low-temperature LNG liquid storage cylinder, CNG gas storage cylinder, and match with the auxiliary gas station to avoid the intermediate link and repeated procedure. Due to the easy long-distance transportation of LNG and the adoption of L-CNG carburetted concept, the primary gas station is established efficiently and fast, and the establishment of CNG marketing network across the country is easy. The brand new primary and auxiliary gas stations do not use any compressor in the whole process, with low daily consumption, and high benefit. Compared with the advanced technologies introduced from abroad, namely compressor-type and hydraulic CNG marketing network, the invention has major advantages in technology and cost.

Description

technical field [0001] It involves the method and equipment for establishing a parent gas filling station, and it is a supporting tool for the previous patent application titled "Sub Gas Filling Station". The gas device constitutes the parent gas filling station to vaporize LNG liquefied natural gas to provide a steady stream of CNG compressed natural gas for the sub gas filling station. [0002] The parent gas filling station of the present invention quickly and flexibly forms a sales network for transforming liquid natural gas LNG into compressed natural gas CNG with child gas filling stations. Background technique [0003] In order to refill vehicles using compressed natural gas (CNG) as fuel, the conventional method is to form a sales network in the form of "child-mother stations" to refill CNG fuel vehicles. [0004] The function of the existing parent gas filling station is to take gas from the natural gas transmission pipeline (road) in my country at present, enter t...

AI Technical Summary

Problems solved by technology

[0006] The disadvantages are: taking gas from the natural gas transmission pipeline (road), the process is complicated, the equipment is various, and it is limited by the peak of residents' gas consumption, so the gas consumption is not guaranteed

[0010] Disadvantages are: low-temperature storage tanks and gas storage tanks in stations require huge investment and are difficult to popularize

This mode occupies trailer resources and increases compressor, hydraulic pump machinery, power consumption

The need for power distribution and capacity expansion requires transformers and other equipment, and a series of safeguard measures such as fire protection facilities need to be added, which increases the difficulty of land use and approval, which causes the cost of gas filling stations to be greater than the price of natural gas raw materials. This is also CNG gas filling. One of the main reasons why it is difficult to build a network in our country
