Description

Technical Field

[0001] In general, the utility model belongs to the technical field of water treatment. Specifically, the utility model relates to a Y-type filter and a water treatment online detection device using the filter. Background Art

[0002] Intelligent dosing of water treatment chemicals is the key to saving water treatment costs and ensuring safe operation of the system. Compared with traditional control methods, through real-time monitoring of the actual concentration of water treatment chemicals in the system and intelligent control, the amount of chemicals added can be changed in time, and the concentration fluctuation of chemicals is small, which can effectively reduce the risk of system operation. Accurate detection of chemical concentration is the prerequisite for realizing intelligent dosing of water treatment chemicals, and currently most online detection devices for chemical concentration use fluorescence monitoring.

[0003] Since fluorescence detection is a detection method based on optical principles, whether the light path propagation is blocked directly affects the test results. Therefore, the accuracy and repeatability of the fluorescence sensor detection results are related to the medium state and the cleanliness of the sensor. If the detected fluid contains a large number of bubbles or has a large turbidity, it will affect the accuracy of the fluorescence detection results. At the same time, the water in the water treatment system generally contains a certain amount of scale-forming ions such as calcium, magnesium, carbonate, and bicarbonate. Under certain temperature and alkalinity conditions, dirt will adhere to the surface of the wall, and even microorganisms will grow and adhere. If not controlled, the fluorescence detection sensor will seriously affect the light path during operation due to dirt adhesion or microbial growth, thereby affecting the accuracy of the detection results. However, the existing online detection device does not solve this problem well. The accuracy of the online detection effect of the fluorescence sensor has limited the promotion and application of this technology to a certain extent.

[0004] In the prior art, a common method for controlling water quality is to add water quality stabilizers such as scale inhibitors, corrosion inhibitors, bactericides and algaecides to water. This method of adding agents is relatively cumbersome, and the addition is batch-based. As time goes by, the performance of the agents gradually decreases, causing the water quality to gradually deteriorate.

[0005] However, there are few reagent dosing devices specially set up for online detection devices, and there are no reports on controlling water quality by slow-release dosing of reagents to improve the detection effect of fluorescent sensors. Utility Model Content

[0006] In order to improve the accuracy of the online detection effect of the fluorescent sensor and overcome the above-mentioned shortcomings in the prior art, the utility model provides a special Y-type filter and a water treatment online detection device using the filter.

[0007] Specifically, the utility model provides the following technical solutions.

[0008] Technical Solution 1: A water treatment online detection device, comprising a Y-type filter, the Y-type filter having a main pipe, a filter element, a flange and fasteners, characterized in that the Y-type filter is also connected to a fluorescent sensor, the filter element of the Y-type filter is filled with a filtering part, and is also filled with a scale inhibition part, an anti-biological attachment part and a defoaming part.

[0009] Technical Solution 2: According to the water treatment online detection device according to Technical Solution 1, the scale inhibition part, the anti-biological attachment part and the defoaming part are physical devices.

[0010] Technical Solution 3: According to the water treatment online detection device described in Technical Solution 1, the scale inhibition part, the anti-biological attachment part and the defoaming part are slow-release water treatment agents.

[0011] Technical Solution 4: According to the water treatment online detection device described in Technical Solution 3, the sustained-release water treatment agent is made into a porous structure, a diaphragm structure, a grid structure or large particles.

[0012] Technical Solution 5: According to the water treatment online detection device described in Technical Solution 1, the filtering part is one or more of sand filter, filter cotton, and porous medium.

[0016] Technical Solution 9: According to the water treatment online detection device according to any one of Technical Solutions 1-8, the water treatment online monitoring device also includes a separate filtering component.

[0017] When the Y-type filter of the utility model is used in the water treatment online detection device of the utility model, its structure is compact, and within one maintenance cycle, the turbidity of the water to be treated can be stably reduced, the scaling tendency can be reduced, and the biological adhesion and foam can be reduced, thereby improving the accuracy of the detection. The scale-blocking part, the anti-biological adhesion part and the defoaming part filled in the Y-type filter of the utility model are all sustained-release agents or physical devices with good durability, which can continue to work for a longer time, thereby reducing the maintenance frequency and reducing the operating cost.

[0023] The utility model is described in detail below in conjunction with the accompanying drawings.

[0024] The utility model provides a Y-type filter and an online water treatment detection device using the filter. The basic structure of the Y-type filter of the utility model is similar to that of the existing Y-type filter, and is provided with a connecting pipe, a main pipe, a filter basket, a flange, a flange cover and a fastener. A filter element is installed in the filter basket. The utility model is to fill the anti-scaling part and the anti-biological attachment part in the filter element. According to the needs, the defoaming part and / or the filtering part can also be filled in the filter element. In the utility model, the anti-scaling part, the anti-biological attachment part and the defoaming part can be physical equipment or chemical agents. The physical equipment can be the commonly used existing equipment, the chemical agent can be the commonly used anti-scaling agent, the algae inhibitor or the biocide, and the defoaming agent can be the commonly used defoaming agent, which will not be specifically listed here. Preferably, these agents use slow-release agents, which can play a role within a maintenance cycle. These slow-release agents can be made into porous structures, membrane structures, grid structures or large particles. The filtering part can use commonly used filtering equipment, for example, it can be one or more of sand filter, filter cotton and porous medium.

[0025] On the other hand, the utility model also relates to an online water treatment detection device, which includes the above-mentioned Y-type filter and the fluorescent sensor. In addition to the above-mentioned Y-type filter and the fluorescent sensor, the online water treatment detection device of the utility model may also include other conventional equipment and instruments, such as pumps, information receiving and processing equipment, controllers, filtering equipment, other monitoring instruments, etc. These conventional equipment are not listed here one by one.

[0026] When the filter element of the Y-type filter is not filled with the filtering part, a separate filtering component can be connected in series with the Y-type filter with the filtering component in front, and then the Y-type filter is connected to the fluorescence sensor; when the filter element of the Y-type filter is filled with the filtering part, the Y-type filter is directly connected to the fluorescence sensor.

[0027] Example 1

[0028] The filter cotton, solid granular slow-release antiscalant, slow-release biocide and defoamer are sequentially loaded into the Y-type filter. The structural diagram is shown in the figure. Figure 1 The Y-type filter is connected with the fluorescence sensor to form an online water treatment detection device, as shown in FIG. Figure 2 As shown, the water treatment agent 1 is put into the water tank 2, the treated water is pumped into the detection device by the pump 3, flows through the Y-type filter 4 for filtration, and the concentration of the agent is monitored online by the fluorescent sensor 5, and the monitored information is transmitted to the information receiving and processing device 6, and the water treatment agent 1 is automatically controlled by the controller 7 to be put into the water tank 2.

[0029] Usage and effect: In the continuous monitoring system of reagent concentration, natural seawater from the Bohai Sea was used as the test medium to carry out the antiscalant concentration detection experiment labeled with sodium pyrene tetrasulfonate. When the Y-type filter was installed at the front end of the fluorescent sensor, the sensor surface was still very clean after the system was continuously running for 10 days; in the comparison test without the Y-type filter, a layer of dirt adhered to the sensor surface after 10 days of operation.

[0030] Example 2

[0031] The grid-shaped slow-release antiscalant and biocide are sequentially loaded into the Y-type filter. The structural diagram is shown in Figure 3 As shown, a separate filtering device is connected in series with a Y-type filter, and then connected to a fluorescent sensor to form an online water treatment detection device, such as Figure 4 As shown. The water treatment agent 1 is put into the water tank 2, and is filtered through the Y-type filter 4 via the pump 3. The concentration of the agent is detected online by the fluorescent sensor 5. Before the information is transmitted to the information receiving and processing device 6, a filtering device 8 and other monitoring instruments 9 are connected in sequence after the pump 3 and before the Y-type filter 4, that is, between the Y-type filter 4 and the pump 3. In other words, the filtering device 8 and other detection instruments 9 are connected in series with the Y-type filter 4; after filtering by the Y-type filter 4, the fluorescent sensor 5 will monitor the concentration of the agent online, and transmit the information to the information receiving and processing device 6, and then the controller 7 is used to control the water treatment agent 1 to be put into the water tank 2.

[0032] Usage and effect: In the continuous detection system of reagent concentration, natural seawater from the Bohai Sea was used as the test medium, and a small amount of surfactant was added to carry out the antiscalant concentration detection experiment labeled with sodium pyrene tetrasulfonate. When a filter device and a Y-type filter were installed at the front end of the fluorescent sensor, the sensor surface was still very clean and the data was stable after the system was continuously running for 10 days; the comparison test without the filter device and the Y-type filter showed that a layer of dirt adhered to the sensor surface after 10 days of operation, and the data was unstable due to small bubbles in the medium.
