Abstract

The invention creatively provides a gas drying device for a CNG station. The gas drying device comprises a drying tank and a gas supply tank, wherein the drying tank comprises a drying tank body and ahemispherical cover body; a first exhaust port is formed in the top of the hemispherical cover body, the gas supply tank is arranged inside the drying tank, a gas inlet is formed in the bottom of thegas supply tank and is communicated with a gas supply pipe, a second exhaust port is formed in the top of the gas supply pipe, a drainage hole is formed in the bottom of the drying tank body, a sealing plug is arranged at the drainage hole, a through hole for the gas supply pipe to penetrate through is formed in the middle of the sealing plug, a plurality of drainage through holes are formed in the sealing plug, an umbrella-shaped flow guide plate is arranged in the middle of the drying tank body, a plurality of condenser pipes are distributed on the umbrella-shaped flow guide plate in a coiling manner, a plurality of air vents are formed in the umbrella-shaped flow guide plate, and a drying agent layer is arranged at the upper part of the drying tank body. The gas drying device for the CNG station, creatively provided by the invention, has the advantages of being simple in structure, low in cost, high in natural gas separation and dehydration efficiency and good in drying effect.

Description

technical field [0001] The invention belongs to the technical field of CNG filling equipment manufacturing, and in particular relates to a gas drying device for a CNG filling station. Background technique [0002] During the process of storing compressed natural gas and filling the car with gas, under high pressure storage, compressed natural gas may precipitate liquid water. The existence of liquid water will cause serious damage to the safety of cars and filling stations, such as causing ice blockage in the system, As a result, gas filling stations cannot achieve normal gas filling, and cars cannot start and run; the existence of liquid water strengthens the corrosion of pressure vessels and pipelines by acidic components, and hydrogen sulfide stress corrosion cracking and carbon dioxide corrosion cracking may occur, leading to disasters such as explosions occurrence of sexual accidents. Therefore, meeting the standard water content of compressed natural gas is very impor...
