Lossless anti-blocking drainer for compressed gas condensate

Abstract

The invention belongs to the technical field of compressed gas purification, in particular to a lossless anti-blocking drainer for compressed gas condensate. The drainer comprises a controller, an electromagnetic drain valve and a non-contact liquid level sensor; a first timer, a second timer and a third timer are arranged in the controller in a matched mode, wherein the first timer is used for setting the work period of the electromagnetic drain valve, the second timer is used for starting the electromagnetic drain valve at regular time, and the third timer is used for controlling the drainage duration of the electromagnetic drain valve; the controller integrates the first timer, the second timer, the third timer and water existence or no-water signals sent by the non-contact liquid levelsensor to control the electromagnetic drain valve to execute opening or closing operation; through cooperation of the non-contact liquid level sensor, the first timer, the second timer and the thirdtimer, scientific control over the electromagnetic drain valve is achieved, and the action frequency of the electromagnetic drain valve is reduced; all condensate water is discharged every time wateris discharged, no water or dirt remains in a water discharging pipeline and an electromagnetic water discharging valve, and the electromagnetic water discharging valve is not prone to being corroded and blocked by liquid.

Description

technical field [0001] The invention belongs to the technical field of compressed gas purification, and in particular relates to a non-destructive anti-blocking drainer for compressed gas condensate. Background technique [0002] Compressed gas is widely used in industrial production. After the gas is compressed and condensed, a large amount of condensed water will be generated. This condensed water is not conducive to the normal operation of gas-consuming equipment. The specific performance is that the condensed water on the pneumatic equipment will carry the lubricating oil walking, resulting in reduced or even damaged equipment efficiency; accelerated wear of valves in the pipeline, resulting in failure or misoperation of pneumatic control equipment; corrosion of pipelines and equipment, and if water freezes at the low point of the pipeline, the pipeline will still be damaged. Dangerous; if the compressed air used for spraying contains water vapor, it will directly affect...

Problems solved by technology

Among them, manual discharge is a waste of manpower and has poor reliability; the principle of mechanical float water discharge is to lift the float at the liquid level inside the container, set the height, and the float mechanically opens the liquid level discharge device, without external power supply, low investment Cost, discharge according to the amount of condensate produced, less gas loss, the disadvantage is that impurities are easy to accumulate, which is easy to affect reliability, and requires frequent maintenance; the time relay electronic discharger is discharged by manually setting the time relay opening time and solenoid valve opening time to control the discharge of condensate, the investment cost is moderate, and the installation is simple, but in the case of less condensate, the discharge solenoid valve is still opened according to the set time, resulting in excessive leakage of compressed gas, and the discharge aperture of the drain valve is small, which is easy to occur Blockage and poor reliability; the non-destructive liquid level sensing electronic drain is not easy to block, it performs start-stop control according to the water level detected by the built-in liquid level sensor, there will always be water in the drain, and dirt will inevitably accumulate over time, and The water storage in the drain is limited, and the frequent start and stop of the drain will inevitably shorten the life of the drain
