Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of natural gas transmission, and in particular relates to a liquid discharge device and a sewage discharge system of a pre-filter of an air compressor. Background Art
[0002] The air compressor currently used in the Sichuan-East Gas Transmission Project is a skid-mounted device. The compressed high-pressure air is roughly filtered in the pre-filter to filter out moisture, oil, and solid particles in the air and discharge them through a float-type automatic drainer. The working principle of the float-type automatic drainer is that when the moisture in the filter reaches a certain height, the float floats up to automatically discharge the moisture and impurities at the bottom of the pre-filter. Whether the moisture at the bottom of the pre-filter can be discharged in time is crucial to air treatment and directly affects the dew point of compressed air. However, the pre-filter currently used is prone to rust, and the filter mesh of the float-type drainer is dense, which causes the float-type drainer to be frequently blocked, resulting in poor drainage of the pre-filter. In addition, the float-type drainer currently used cannot intuitively judge whether there is water accumulation inside and whether it can discharge sewage normally. Moreover, the current float-type drainer can only discharge sewage automatically and cannot be manually operated to discharge sewage. Utility Model Content
