Embodiment Construction

[0029] Embodiments of the present invention will be described with reference to the drawings. figure 1 It is a figure which shows the structure of the defoaming apparatus 100 which concerns on this embodiment. The defoaming apparatus 100 of this embodiment is especially suitable as an apparatus arrange|positioned in the preceding stage of the high-sensitivity turbidimeter for the measurement water of low turbidity. However, the defoaming apparatus 100 can also be used as an apparatus arranged in the preceding stage of other turbidimeters. In addition, the defoaming apparatus 100 is not limited to a turbidity meter, and can be disposed in the preceding stage of a measuring device that preferably removes air bubbles from measurement water, such as a colorimeter, a water quality monitor, a pH meter, a conductivity meter, or a residual chlorine gas tester. device to be used.

[0030] like figure 1 As shown, the defoaming apparatus 100 of this embodiment is provided with the s...

Abstract

One object of the embodiments of the present invention is to realize a degassing device which is suitable as a device arranged before a high-sensitivity turbidimeter and has a simple structure. The defoaming device is a defoaming device for removing air bubbles in the measurement water, and includes a swirl flow generating unit and a first defoaming tank. The swirl flow generation unit includes a funnel, a swirl channel for guiding the measurement water to an upper portion of the funnel, and a tube for guiding the measurement water flowing out of the funnel in a first horizontal direction. The first defoaming tank houses the funnel and the tube. The 1st degassing tank has the bottom which inclines to the 2nd direction side which faces opposite to a 1st direction, and the 1st outflow port formed in the 2nd direction side.

Description

technical field [0001] The invention relates to a defoaming device. Background technique [0002] A turbidity meter measures turbidity, which is an index representing the degree of turbidity of water. In a turbidimeter, air bubbles in the water can affect the measurement. Therefore, in many cases, a defoaming device (a defoaming tank) is installed in the front stage of the measuring instrument. As the form of the defoaming device, the atmosphere open type, the pressurized type, and the swirl type have been put into practical use. [0003] The air-opening type defoaming apparatus utilizes the principle that the air bubbles in the water naturally rise under the atmospheric pressure and reach the liquid surface. The gas is separated from the liquid by retaining the measurement water in the defoaming device. The larger the tank of the defoaming device, the longer the residence time of the measured water, and the better the defoaming effect. [0004] In a pressurized defoami...
