Description

Technical Field

[0001] The utility model relates to the field of wastewater monitoring, in particular to a Ross foam meter device. Background Art

[0002] Foam-containing wastewater is a common type of wastewater in natural gas exploitation. During the process of natural gas exploitation, with the in-depth development of natural gas, the single-well natural gas production decreases rapidly. The foam drainage gas production process is generally adopted to increase the natural gas production. The foam drainage gas production process is to inject the foam drainage agent into the annulus between the tubing and the casing, mix it with the wellbore liquid accumulation, and with the agitation of the natural gas flow, use the foam effect, dispersion effect, drag reduction effect and washing effect of the surfactant and other components in the foam drainage agent to generate low-density water-containing foam in the wellbore, reduce the liquid density, improve the vertical lifting capacity of the gas flow and the liquid-carrying capacity of the gas well, so as to achieve the purpose of increasing the single-well natural gas production. However, a large amount of foam-containing wastewater will also be generated. This type of wastewater has the characteristics of strong foaming ability and great treatment difficulty. When using the low-temperature multi-effect distillation technology to treat the foam-containing wastewater, there are strict requirements for the foaming power index of the wastewater entering the distiller. Once the defoaming is insufficient, accidents such as tower overturning will occur in the distiller, which may lead to the shutdown of the equipment and seriously affect the normal progress of distillation. Nowadays, the Ross foam meter is mostly used as the measuring equipment for foam. When the Ross foam meter is measuring, the dropper needs to be aligned with the midpoint of the graduated measuring tube for measurement. Otherwise, when the liquid is injected, the liquid flow will deviate from the center, affecting the stability and uniformity of the foam column. However, in the traditional Ross foam meter, since the dropper and the graduated measuring tube are separate, manual alignment of the midpoint of the dropper and the graduated measuring tube is required during assembly. This process may lead to inaccurate alignment due to human operation errors, so that the operator needs to repeat it. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the problem in the background art that the graduated measuring tube and the dropper in the traditional Ross foam meter are mostly assembled separately, resulting in the dropper being unable to accurately align with the midpoint of the graduated measuring tube and affecting the accuracy of subsequent measurement, and to provide a Ross foam meter device.
