Description

Automatic condensed water discharging device for gas engine intake pipe

Technical Field

The utility model belongs to the technical field of the gas engine, especially, relate to an automatic comdenstion water device that arranges of gas engine intake pipe.

Background

The pre-treated gas typically enters the cylinders of the engine by the following route: gas → supercharger → intercooler → throttle → piping flame arrester → intake pipe → cylinder head → cylinder.

The gas engine can increase the density of the mixed gas entering the cylinder by increasing the air inlet pressure, so that more fuel can be combusted, the power of the engine is greatly increased, and the economy of the engine is improved. The density of the gas in the air intake system is increased while the gas is compressed, and the temperature is increased, so that the charging efficiency of the cylinder is influenced.

The intercooler plays a role in cooling gas, and the high-temperature supercharged gas is cooled by the intercooler and then enters the engine. The temperature of the pressurized high-temperature gas is greatly reduced after cooling, and the water vapor in the gas is condensed into liquid water under the cooling effect of the intercooler, so that a large amount of condensed water can be formed for a long time. When condensed water is gathered and then enters the air inlet pipe and the air cylinder, the condensed water can enter the oil pan along the wall of the air cylinder sleeve, the lubrication of the air cylinder sleeve is damaged, the engine oil is diluted, the service cycle of the engine oil is shortened, and the use cost is increased; and secondly, liquid water enters the cylinder to be vaporized and absorb heat, so that the power generation efficiency is reduced. If the water quantity is too large, the gas engine top cylinder and other major faults can be caused.

In the prior art, condensed water after cold cooling of a gas engine is discharged by a screw plug or a drain valve arranged at the bottommost end of an air inlet pipe. When the gas engine works, the screw plug is screwed off or the drain valve is opened by a wrench at intervals to drain condensed water, and when the condensed water is drained, the screw plug is screwed on or the valve is closed. Gas can also leak out when water is discharged. The water discharging mode is greatly influenced by human factors, the gas engine is difficult to ensure to discharge water in time, and the labor intensity of workers is high.
