However, the heat generated by gas compression is high. The gas in the cylinder relies on the surface in contact with the cylinder wall to conduct heat, and then conducts heat exchange and conduction between the cylinder wall and the outer water jacket. This external indirect conduction cools down the high heat accumulated inside the gas. Slow, resulting in the heat dissipation speed relying on the water jacket method cannot keep up with the high heat generated by gas compression, and the cooling effect of the water jacket is still not ideal
In order to suppress the rapidly rising temperature, it is necessary to configure a high-power air cooler on the gas pipeline to implement air cooling, resulting in low mechanical efficiency of the entire compressor and high power consumption

The invention discloses an internal cooling type hydraulic pressurized container for natural gas. A shell of the hydraulic pressurized container comprises a container body and upper and lower end covers; a heat exchange tube is arranged inside a container body chamber; the upper end of the heat exchange tube is connected with the upper end cover through an upper fixing base; the lower end of the heat exchange tube is connected with the lower end cover through a lower fixing base; the upper end cover is provided with a cooling medium outlet which is communicated with the heat exchange tube via a passage; the lower end cover is provided with a cooling medium inlet which is communicated with the heat exchange tube via the passage; the upper fixing base is provided with an air vent for natural gas to pass through; a liquid level sensor is arranged inside the air vent and extends into the container body chamber; the lower fixing base is provided with an oil passing hole for hydraulic oil to pass through. According to the internal cooling type hydraulic pressurized container disclosed by the invention, the heat exchange tube for the cooling medium to pass through is arranged inside the hydraulic pressurized container chamber and is used for directly cooling the gas and the hydraulic oil inside the hydraulic pressurized container chamber, so that the cooling speed of compression heat of the gas is increased, and the cooling efficiency of the compressed natural gas and the hydraulic oil is improved.
Description
technical field [0001] The invention relates to a natural gas compression device, in particular to a natural gas internal cooling type hydraulic pressurized container. Background technique [0002] Natural gas compression is an exothermic process, which will generate a large amount of heat and increase the temperature of the gas, and the higher the compression ratio, the higher the temperature rise. This temperature rise will not only affect the life of some seals, but also reduce the intake air volume and reduce the exhaust air volume. At present, the total compression ratio of the natural gas compression device in the natural gas filling station is as high as 8 or more, and the temperature of the gas is high. After the first stage of compression, the gas must be cooled to reduce the temperature of the compressed gas to 40-45°C before entering the next stage of compression. However, the existing natural gas compression equipment usually adopts an external cooling method, ...
