Oil and water/gas two-stage separator for braking gas

Abstract

The invention discloses an oil and water / gas two-stage separator for braking gas, which is used for two stages of separation of oil and gas, and water and gas for the braking gas of heavy trucks. The first stage is carried out by a centrifugal separation method, and the separation efficiency is 50 to 70 percent; and the second stage is the key of the invention, wherein a filter element is made offilter paper subjected to surface treatment of organic silicon, and has strong functions of affiliating oil and repelling water. When gas containing water and oil passes through the separator, the filter element blocks water in the gas on the surface of the filter paper by the water repelling function of the filter element, and the water forms small droplets and the small droplets gradually become big and slide into a sewage storage tank; and by the oil affiliating function of the filter paper, the filter element adsorbs oil in the gas and makes clean gas pass through. The gas containing the oil and the water is subjected to two-stage separation, and the separation efficiency is over 90 percent. When an automobile does not work, oil on the filter element drops into the sewage storage tank; before the automobile is started every three days (or every week), a blowoff valve is opened to discharge dirt such as oil, water and the like; and the blowoff valve is closed before the automobile is started.

Description

technical field [0001] The invention relates to a technique for separating gas and oil and gas and water of braking gas of an automobile air braking system, in particular to an oil, water / gas double-stage separator of braking gas. Background technique [0002] In order to ensure the safety and reliability of the air brake system of heavy-duty vehicles, the air used in the system must be water-free and oil-free. [0003] At present, most of the brake gas used in the air brake system of heavy-duty vehicles in my country adopts the drier imported from abroad for anhydrous treatment, and its technology is basically in place. Adsorption and desorption measures, but from the use of practice, the capacity of its molecular sieve is still not enough. However, the design of the dryer for brake gas and oil-free treatment is very unreasonable, only a small space is left, and polyester fiber is used to absorb oil. During use, this part of the polyester fiber will soon be filled with oil...
