Water-air-oil separating device for water jetting screw air compressor

Abstract

The invention belongs to the technical field of oil gas recovery of air compressors and particularly relates to a water-air-oil separating device for a water jetting screw air compressor. The water-air-oil separating device for the water jetting screw air compressor comprises a tank body, an air inlet pipe, an air outlet and an oil outlet, wherein the tank body is provided with the air outlet; a bushing corresponding to the air outlet is arranged in the tank body; the tank body is internally provided with a separation board; the inner part of the tank body is divided into an upper part and a lower part by the separation board; a blowdown pipe is arranged at the bottom of the tank body; a communicating pipe is arranged on one side, positioned at the upper-half part of the tank body, of theseparation board; a downflow spout is arranged on one side, positioned at the lower-half part of the tank body, of the separation board; a water outlet interface is formed in one side of the tank bodyand is communicated with a water outlet pipe inside the tank body; the oil outlet is formed in the other side, corresponding to the water outlet interface, of the tank body. The water-air-oil separating device has the beneficial effects that the structure is simple and the size is small; condensate water and oil in compressed air can be collected and separated, and recycling of the condensate water is realized, so that the pollution to environment is avoided.

Description

technical field [0001] The invention belongs to the technical field of oil and gas recovery of air compressors, and in particular relates to a water-gas-oil separation device for a water-spraying screw air compressor. Background technique [0002] The compressed air produced by the air compressor needs to pass through the dryer to cool and dry the compressed air, and then pass through the air storage tank to maintain the pressure. Since the condensed water in the air may accumulate in the oil tank, especially in humid weather, when the air compressor exhaust temperature is lower than the pressure dew point of the gas or is shut down for cooling, more condensed water will be precipitated, which will affect the safe operation of the machine At the same time, since the air compressor needs to use lubricating oil to lubricate the body during operation, a small amount of lubricating oil (1-3ppm of oil) will be entrained in the compressed air, and this part of lubricating oil will...
