DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present utility model and its application or use. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0019] Unless otherwise specifically stated, the relative arrangements, numerical expressions and values of the components and steps set forth in these embodiments do not limit the scope of the present utility model. In all the examples shown and discussed here, any specific value should be construed as merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0020] Example 1: As Figure 1 shown, an on-line monitoring device for the solution concentration of a heat source tower includes a first heat source tower solution pipe section 41, a second heat source tower solution pipe section 51, a three-way pipe 3, and a densitometer 1.
[0021] The three-way pipe 3 includes a heat source tower solution accommodating part 31 and a densitometer mounting part 32 that are connected and communicated; the first end of the heat source tower solution accommodating part 31 is communicated with the first heat source tower solution pipe section 41, the second end of the heat source tower solution accommodating part 31 is communicated with the second heat source tower solution pipe section 51, the densitometer 1 is installed in the densitometer mounting part 32, and the detection part of the densitometer 1 is located in the heat source tower solution passing through the heat source tower solution accommodating part 31.
[0022] In this application, by setting a three-way pipe in the heat source tower solution pipe section and setting a densitometer in the three-way pipe to realize on-line monitoring of the solution concentration in the pipeline, after the solution concentration changes, it is convenient for management personnel to make corresponding adjustments to maintain the stability of the system, which has important economic value and social value and is easy to promote and apply.
[0023] In some embodiments, the heat source tower solution accommodating part and the densitometer mounting part are perpendicular to each other, and the heat source tower solution accommodating part is horizontally arranged.
[0024] In some embodiments, the connecting end of the densitometer mounting part is located in the middle of the heat source tower solution accommodating part.
[0025] In some embodiments, the on-line monitoring device for the solution concentration of the heat source tower further includes a flange 2, and the densitometer 1 is hermetically installed at the installation end of the densitometer mounting part 32 through the flange 2. In this embodiment, the flange 2 is openable and closable. When it is necessary to take a sample from the pipeline, the flange 2 can be opened to take a sample from the densitometer mounting part 32.
[0026] It should be noted that setting the flange 2 at the installation end of the densitometer mounting part in this application has at least two functions: First, it is used to fixedly install the densitometer, and second, it is used to achieve the overall sealing of the pipeline.
[0027] In some embodiments, a first valve 42 for opening and closing the pipeline is provided in the first heat source tower solution pipe section 41.
[0028] In some embodiments, a second valve 52 for opening and closing the pipeline is provided in the second heat source tower solution pipe section 51.
[0029] It should be noted that in this application, by setting the first valve 42 and the second valve 52, the opening and closing of the first heat source tower solution pipe section and the second heat source tower solution pipe section can be realized respectively. In this way, it is convenient to open the first valve and the second valve during the subsequent operation process when the heat source tower is operating normally, so as to keep the entire heat source tower solution pipe section unobstructed. When sampling is required, the first valve and the second valve are closed, and sampling can be carried out through the three-way pipe 3.
[0030] In some embodiments, the on-line monitoring device for the concentration of the heat source tower solution further includes a first flange 43 and a second flange 53. The first end of the heat source tower solution accommodating part 31 is connected to the first heat source tower solution pipe section 41 through the first flange 43, and the second end of the heat source tower solution accommodating part 31 is connected to the second heat source tower solution pipe section 51 through the second flange 53.
[0031] In some embodiments, the density meter 1 is a tuning fork density meter.
[0032] The working principle of the tuning fork density meter is designed based on the vibration principle of components. The tuning fork density meter utilizes the relationship between the density of solid materials and their influence on the sound wave propagation speed. The tuning fork used in the tuning fork density meter is made of a slender metal rod, shaped like an inverted "U". The tuning fork can be excited by an electromagnetic or piezoelectric device to make it vibrate. At the same time, the built-in sensor or detector monitors the vibration state of the tuning fork. When sound waves propagate through materials with different densities, their propagation speed will change, thus affecting the vibration of the tuning fork. The density of the material is determined by measuring the resonance frequency of the tuning fork. Materials with higher density will cause the sound wave propagation speed to decrease, thus reducing the resonance frequency of the tuning fork; while materials with lower density will cause the sound wave propagation speed to increase, and the resonance frequency of the tuning fork will also increase accordingly. According to the previously calibrated and experimental data, the measured resonance frequency is compared with the corresponding density to determine the density of the substance to be measured.
[0033] The tuning fork density meter has the advantages of high sensitivity, non-invasiveness, simple operation, etc. It is commonly used for the density measurement of liquids and solids and is widely used in many industries, such as chemistry, pharmacy, petroleum, etc.
[0034] Embodiment 2: Based on Embodiment 1, this embodiment provides a working method for the above-mentioned on-line monitoring device for the concentration of the heat source tower solution, including:
[0035] When the system is running, as Figure 1 shown, when using the on-line monitoring device for the concentration of the heat source tower solution to detect the solution concentration, the first valve 42 and the second valve 52 are closed to cut off the flow of the pipeline solution, and the sample solution at this time is obtained through the three-way pipe 3. The detection end of the density meter 1 is immersed in the solution, and after measuring the solution density, the concentration of the solution at this time is obtained by referring to the density table of the solution.
[0036] In this embodiment, the densitometer is preferably a tuning fork densitometer.

Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features.
