Abstract
The utility model discloses a cooler for compressed natural gas and relates to an accessory device in a CNG injection station that solved the technical problems of poor radiating effect and the likely incrustation on air stream tubes of the existing cooling device for compressed natural gas in CNG injection stations. The utility model is comprised of an air stream tube that is coiled as a S shape and a water stream tube outside the air stream tube; wherein, the air stream tube is sleeved outside the water stream tube; the water stream tube is sleeved on the straight line part on the air stream tube in divided sections; sections of the water stream tube is communicated with each other through connecting tubes; and the direction of water stream inside the water stream tube is opposite to that of the air stream inside the air stream tube. The utility model has a good cooling effect and can carry out cooling repeatedly; the radiating effect of the cooler is good, and the tube wall of the air stream tube is unlikely to have incrustations, thus the utility model can be wildly applied in various CNG injection stations for cooling the compresses natural gas.
Description
Technical field
The utility model relates to the accessory of a kind of CNG (compressed natural gas) gas station, particularly a kind of compressed natural gas cooler.
Background technique
Rock gas becomes one of main separation fuel of automobile day by day owing to its Economy, the feature of environmental protection.Rock gas is as automotive fuel, and its CO discharge amount reduces more than 90% than gasoline, and hydrocarbon emission reduces more than 70%, and the oxynitrides discharging reduces more than 35%, is not only environmental protection but also economic fuel at present.
Just as many gas stations, gas station is the fuel supplement place of numerous gas combustion automobiles.Rock gas adds before the automobile, must be through overcompression, and in the process of compressed natural gas, the temperature of rock gas can rise.Therefore, many CNG gas station all is provided with cooling unit so that compressed natural gas is cooled off, and mostly these cooling units are cooling tank or cooling pond, and the airflow line of compressed natural gas is positioned over wherein, and rock gas is cooled off.The cooling unit self-radiating weak effect of this structure, easily fouling on natural gas line, the engineering work load of maintenance is also big.
The model utility content
The purpose of this utility model is: solve the technical barrier of easy fouling on existing CNG gas station compressed natural gas cooling unit self-radiating weak effect, the airflow line, compressed natural gas cooler less scaling on a kind of cooling capable of circulation, good heat dissipation effect, the airflow line is provided.
The purpose of this utility model realizes by following technical proposals:
The compressed natural gas cooler includes the outer cooler of airflow line and airflow line, and described cooler is a water pipe, and airflow line is enclosed within the water pipe.
Described airflow line bending is spiraled and is snakelike, and the water pipe segmentation is enclosed within the straight section of airflow line outward, is communicated with by connecting tube between every section water pipe.
The inlet/outlet of described airflow line is provided with inlet flange and the flange of giving vent to anger, and the inlet/outlet of water pipe is provided with water-in flange and water-output flange.
Described inlet flange and water-output flange are positioned at the same end of described compressed natural gas cooler, and give vent to anger flange and water-in flange are positioned at another same side of described compressed natural gas cooler.
The utility model puts water pipe outside airflow line, take away the heat of the compressed natural gas of airflow line and inside thereof with flowing water, can effectively reduce the temperature of compressed natural gas on the one hand, reach its usage requirement, and pass to the current of certain pressure in the water pipe, because the pressurized flow of water is less scaling on the airflow line outer wall; The snakelike airflow line that bending is spiraled can reduce space hold, is communicated with connecting tube between every section water pipe, not only guaranteed the unobstructed of water pipe, and connecting tube also has supporting effect to every section water pipe; The air inlet, the flange of giving vent to anger that are provided with are convenient to this cooler with water inlet, water-output flange and are connected with other equipment; Inlet flange, water-output flange are positioned at same end, give vent to anger flange, water-in flange is positioned at another same side, such structure makes air-flow opposite with the flow direction of current, when current flow to the suction port place of airflow line, current raise because of absorbing the heat temperature, have avoided suction port to be in the airflow line of the condition of high temperature because of meeting cold tube wall explosion.As seen, adopt the utility model of said structure, compare with existing cooling tank or cooling pond, good cooling results, cooling capable of circulation, the cooler self-radiating is effective, and less scaling on the tube wall of airflow line, can be widely used in various CNG gas station cooled compressed rock gas.

Embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
As shown in Figure 1, the compressed natural gas cooler is made of airflow line 1, water pipe 2, water-output flange 3, inlet flange 4, connecting tube 5, the flange 6 of giving vent to anger, water-in flange 7.As shown in Figure 2, airflow line 1 is enclosed within the water pipe 2, and airflow line 1 bending is spiraled into snakelike, and water pipe 2 segmentations are enclosed within every section straight section of airflow line 1, each section water pipe 2 is communicated with by connecting tube 5, and connecting tube 5 also has supporting effect to each section water pipe 2.The inlet/outlet of water pipe 2 is drawn from water pipe 2 sidewalls at the two ends of cooler.Inlet flange 4 and water-output flange 3 are positioned at the upper end of cooler, and give vent to anger flange 6 and water-in flange 7 are positioned at the lower end of cooler.
During use, compressed natural gas is entered by the inlet flange 4 of upper end, gas is from top to bottom discharged to the flange 6 of giving vent to anger of cooler lower end, cooling water is entered by the water-in flange 7 of cooler lower end, and current are from bottom to top discharged to the water-output flange 3 of cooler upper end, and the current size is controlled by gate valve, when current arrive the cooler upper end, because it absorbs heat, temperature raises, thereby has avoided upper end airflow line 1 because of gathering the cold tube wall explosion that causes.
This cooler multiple-unit as required connects use, to strengthen cooling effect.Every unit cooler is in light weight, installs, lifting is flexible, and the temperature of airflow line 1 suction port is about 30 ℃ through the cooled air outlet temperature of this cooler in the time of 90 ℃, has reached the technological requirement of rock gas compression.
