Problems solved by technology

Water inlet pipe plus filter membrane defoaming method, the most commonly used online monitoring system defoaming method, after water passes through the filter membrane, the internal dissolved gas is filtered out, the filter membrane is expensive and has a short life, and it is difficult to replace
[0005] At the same time, the heating method, ultrasonic defoaming method, vacuum defoaming method, these methods require a larger volume and power defoaming mechanism, consume additional power, and are not suitable for online monitoring equipment
The method of adding a filter membrane to the water inlet pipe commonly used by online monitors will filter out the components that need to be detected in the water body while removing foam, which will affect the test results, and the filter membrane is expensive and difficult to maintain.

Abstract

The invention provides a defoamer, which comprises a cylinder body, a hydrophobic membrane and an end cap, wherein a liquid storage chamber with an open upper end is arranged in the cylinder body, the end cap is located at the upper end of the cylinder body, and the end cap covers Set at the upper opening of the liquid storage chamber; the lower side of the cylinder is provided with a water outlet port communicating with the liquid storage chamber; the end cover is provided with a water inlet port communicated with the liquid storage chamber ; The end cover is provided with a defoaming gap with an open upper end, and the defoaming gap is isolated from the liquid storage chamber by the hydrophobic membrane. The bubble remover provided by the invention has small volume and simple structure, does not need to consume extra electric energy and does not affect the composition of the sample liquid.

Description

technical field [0001] The invention relates to the technical field of online water quality monitoring, in particular to a defoamer used in the technical field of online water quality monitoring. Background technique [0002] In the field of water quality online monitoring technology, it is specifically the online monitoring of suspended particles in oilfield reinjection water. During the monitoring process, real-time sampling and detection of water samples inside the oilfield water injection wells is required, and air bubbles will be mixed into the sample water during the sampling process, which greatly affects the accuracy of the detection results. [0003] Therefore, it is necessary to defoam the sample water. The existing liquid defoaming methods mainly include: heating method, ultrasonic defoaming method, vacuum defoaming method, and the method of adding a filter membrane to the water inlet pipe commonly used in online monitors. According to different application fiel...
