Abstract
The utility model relates to a compressed natural gas pressure regulating gas supply device by adopting an air-temperature heat exchanger, which consists of a high pressure rubber pipe, an inlet flange, an emergency cut-off valve, a ball valve, a primary pressure regulating valve, a heat exchanger, a secondary pressure regulating device and an outlet flange, which are connected with each other through pipelines in serial and are fixed on a skid-mounted structure chassis, wherein the pipeline is provided with a pressure meter, a safety valve and an odorizer, four corners of the chassis are provided with four hoisting hooks, and the heat exchanger adopts an air-temperature heat exchanger. The compressed natural gas pressure regulating gas supply device has the advantages that: especially by adopting the air-temperature heat exchanger, the low-temperature natural gas with released pressure is heated by the heat which is collected from the natural air by an aluminum fin pipe on an air-temperature vaporizer, so no additional power source or heat source is required, the adaptability is strong, and the device is particularly more convenient and more flexible for the users with the power source or the heat source being difficult to be provided.
Description
(1) technical field
The utility model relates to a kind of compressed natural gas pressure regulation air feeder, particularly a kind of compressed natural gas pressure regulation air feeder that adopts the air temperature type heat exchanger.
(2) background technique
Natural gas supply generally has dual mode: a kind of is pipeline supply, is applicable to the fixed-site in the big and medium-sized cities; Another kind is by high-pressure gas cylinder compressed natural gas to be transported to the gas station, is fed to the user after heating, decompression, is applicable to the industrial user of samll cities and towns or dispersion.In a kind of mode in back, compressed natural gas is a kind of new natural gas storage mode.The main component of rock gas is methane (CH
4), be compressed to 20MPa through after the desulfurization, dehydration, purification, the rock gas volume is reduced, compressed natural gas is filled in the special high-pressure gas cylinder stores again, with special tank car high-pressure gas cylinder is transported to the gas station then.When the user uses compressed natural gas, generally by heating, decompression, pressure regulation, add smellyly, supply with the user then, this situation is suitable for not having the bigger industrial and mining enterprise and the residential belt of pipeline gas supply.At present compressed natural gas is being heated in the link, provide the method for thermal source to adopt circulating hot water or electric heating, this just needs with electric energy, gas water-heating furnace, recycle pump and tubing etc., not only investment is big, the cycle is long, and the applicability of equipment and very flexible, particularly, be difficult to satisfy their air feed requirement for the user that power supply or thermal source difficulty are provided.
(3) model utility content
The purpose of this utility model is at the problems referred to above, provides that a kind of maneuverability is good, applicability is strong, cost is low, can satisfy the compressed natural gas pressure regulation air feeder of employing air temperature type heat exchanger that thermal source provides user's needs of difficulty.
The technical solution of the utility model:
A kind of compressed natural gas pressure regulation air feeder that adopts the air temperature type heat exchanger, form by high-pressure rubber pipe, suction flange, Emergeny Cutoff Valves, ball valve, one-level pressure regulator valve, heat exchanger, secondary pressure governor and outlet(discharge) flange, be connected in series and be fixed on the skid structural chassis by pipeline, pressure gauge, safety valve and odorization machine are set on the pipeline, the Corner Strapped on chassis has four Lift hooks, and described heat exchanger adopts the air temperature type heat exchanger.
The work characteristics of described air temperature type heat exchanger is: post-decompression cryogenic natural gas heats post-decompression cryogenic natural gas by the heat in the absorption of the aluminum finned tube on the empty temperature vaporizer natural air.
