Abstract

The invention discloses a foam separator for preprocessing produced water. The foam separator comprises an aeration pump, a separation barrel with the bottom being connected with the aeration pump, a communication pipe which is connected with the bottom of the separation barrel and a water outlet pump which is communicated with the communication pipe; more than two baffle plates are arranged in the separation barrel, and a conical foam concentrator for converging the foams is arranged on the top end inside the separation barrel; one side of the bottom end of the separation barrel is provided with a water inlet valve which is connected with the aeration pump, the other side of the bottom end of the separation barrel is provided with a water outlet valve which is connected with the communication pipe, and one side of the upper end of the separation barrel is provided with a foam liquid outlet; the separation barrel is also provided with a liquid level meter. By adopting the foam separator, the traditional Venturi jet pump is canceled, so that the stability and reliability of the device are improved; in addition, the baffle plates are arranged in the separation barrel, so that the stability of the foams is improved, the water content of the foams is reduced, and the separation efficiency is higher.

Description

technical field [0001] The invention relates to a foam separator used for pretreatment of produced water. Background technique [0002] The produced water of Puguang gas field is different from the produced water of general gas fields in China. The water quality exists: high sulfide content, deep color, high COD content (2000-3000mg / L), a large amount of volatile organic compounds, strong foaming, mainly Because it contains a high content of pollutants such as volatile pyridines and their derivatives and polyamine small molecules with high water solubility. [0003] Aiming at the characteristics of produced water in Puguang Gas Field, it is concluded through the pilot test that it is an effective method to control the produced water in Puguang Gas Field by adopting low-temperature multi-effect evaporation as the main process technology to achieve standard discharge treatment. However, due to the strong foaming of the produced water, it directly affects the smooth operation ...
