Description

Technical Field

[0001] The utility model belongs to the technical field of EDI desalination equipment protection, and in particular relates to a device for accurately monitoring EDI desalination equipment damaged by water shortage. Background Art

[0002] In the process of water treatment, EDI desalination equipment is often needed to remove ion salts in water. The clean water treated by EDI desalination equipment is ultrapure water because the metal ion salts are fully removed.

[0003] Ultrapure water does not contain metal ions and is therefore widely used in industry, such as as experimental water.

[0004] During the operation of the EDI desalination equipment, clean water enters the EDI desalination equipment for treatment and is discharged from the water outlet of the EDI desalination equipment. In the actual operation process, in order to increase the amount of treated water, multiple EDI desalination equipment often work at the same time.

[0005] During the operation of the EDI desalination equipment, the water outlet of the equipment often contains weak electricity, which causes partial water electrolysis and generates some bubbles. The generation of bubbles causes the flow meter at the water outlet to measure inaccurately, which in turn causes the operator to be unable to judge the water content in the EDI desalination equipment.

[0006] Especially because the amount of bubbles is relatively large (when there are more bubbles in the water, the measurement accuracy of the flow meter is seriously affected), the amount of water in the EDI desalination equipment is relatively small (such as the amount of water in the EDI desalination equipment decreases due to blockage and other reasons). Once the amount of water in the EDI desalination equipment is relatively small and the flow meter fails to measure accurately and in time, the failure of the EDI desalination equipment will worsen. In severe cases, the EDI desalination equipment will be completely damaged. Utility Model Content

[0007] Based on the above background, the purpose of the utility model is to provide a device for accurately monitoring water shortage and damage to EDI desalination equipment.

[0008] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0040] Example 1

[0041] like Figure 1-5 As shown, a device for accurately monitoring the damage of EDI desalination equipment due to lack of water comprises a plurality of bubble removal mechanisms 3 which are assembled and connected to the water outlet of the EDI desalination equipment. The bubble removal mechanism 3 is used to remove bubbles from the water at the water outlet of multiple EDI desalination equipments working simultaneously (it is found in actual work that the water outlet of the EDI desalination equipment often has weak electricity, which electrolyzes the water and generates bubbles). Bubbles seriously affect the measurement accuracy of the flow meter. The bubble removal mechanism 3 is used to remove bubbles, thereby greatly improving the measurement accuracy of the flow meter, accurately monitoring the water output at the water outlet of the EDI desalination equipment, and accurately judging whether the EDI desalination equipment is lacking in water when working, thereby avoiding damage to the equipment due to lack of water.

[0042] Specifically, the bubble removal mechanism 3 includes a shell 31 (the longitudinal cross-sectional shape of the shell 31 is circular), and the water inlet end of the shell 31 is respectively equipped with a water inlet pipe 311, and the water inlet pipe 311 is equipped with and connected to the water outlet end of the EDI desalination device. At the same time, a bubble removal component 33 is rotatably connected in the shell 31, and the bubble removal component 33 includes inner roller bearings 331 spaced apart on both sides (the outer ring of the inner roller bearing 331 is fixedly assembled on the inner side wall of the shell 31). At the same time, a plurality of obliquely arranged bubble removal plates 333 are respectively fixedly connected to the inner ring of the inner roller bearing 331; the bubble removal plates 333 are made of a light and convenient non-metallic material (the purpose of the non-metallic material is to avoid metal ion contamination) such as plastic material.

[0043] A fixed end seat 3332 is fixedly connected between the outer ends of the bubble removal plates 333, and a connecting shaft 3321 is fixedly connected between the fixed end seats 3332; a driving impeller that drives the bubble removal assembly 33 to rotate is fixedly connected to the connecting shaft 3321; wherein the driving impeller is a conventional impeller driven to rotate by water flow disclosed in the prior art, and its main structure includes a driving impeller including an impeller plate 332, and the impeller plate 332 is fixedly connected with a plurality of impeller push plates 3322 facing the direction of the water flow.

[0044] During operation, driven by the water flow, the lightweight driving impeller drives the connecting shaft 3321 to rotate, thereby causing the debubble assemblies 33 on both sides to rotate.

[0045] Specifically, during the rotation of the bubble removal assembly 33, the bubble removal plate 333 hits the bubbles in the water flow, and under the impact, a large number of bubbles in the water are removed. Since the bubble removal plate is arranged on both sides, the bubbles in the water are fully removed.

[0046] At the same time, after the bubbles are broken, the released gas is discharged through the exhaust pipe 32 connected to the vertical arrangement on the housing 31, and a valve is assembled and connected to the exhaust pipe 32. The valve is opened during operation to discharge the gas. During operation, in order to prevent water from being discharged from the exhaust pipe 32, the exhaust pipe is set at a certain height.

[0047] The above method can effectively remove bubbles from water, thereby improving the measurement accuracy of the flow meter during operation, accurately monitoring the water output of the EDI desalination equipment, and accurately judging whether the EDI desalination equipment is short of water during operation, thus avoiding equipment damage caused by water shortage.

[0048] Example 2

[0049] like Figure 1-5As shown, based on the structure of Example 1, the water outlet end of the shell 31 is connected with a water outlet pipe 11, and the precise monitoring device for water shortage and damage to EDI desalination equipment also includes a water outlet main pipe 1, and the water outlet pipe 11 is connected to the water outlet main pipe 1. Specifically, during the working process, multiple EDI desalination equipments work at the same time, so the production needs are met through the pipeline structure.

[0050] Similar to the existing method, each of the water outlet pipes 11 is connected to a flow meter 2, and the water flow rate is measured by the flow meter 2 to determine the working state of the EDI desalination equipment.

[0051] Example 3

[0052] like Figure 1-5 As shown, based on the structure of Example 1, the shape of the bubble removal plate 333 is as follows: the bubble removal plate 333 includes a curved connection portion fixedly connected to the inner ring of the inner roller bearing 331, the curved connection portion is integrally formed with an oblique body portion, and the oblique body portion is fixedly connected to the fixed end seat 3332. During operation, when the inner roller bearing 331 rotates flexibly, the oblique body portion fully impacts and breaks the bubbles in the water.

[0053] At the same time, in order to improve the bubble breaking effect, the above-mentioned oblique body is provided with a strip hole 3331, and a plurality of bubble breaking plates 34 are fixedly connected in the strip hole 3331; the bubble breaking plates 34 are fixedly connected to the hole walls on both sides of the strip hole 3331. The bubble breaking plates 34 are rectangular in shape and are heat-welded to the strip hole 3331.

[0054] During operation, under the action of the bubble breaking plates 34, the bubble removal effect is enhanced. Specifically, during the rotation process, multiple bubble breaking plates 34 form multiple puncturing portions, thereby enhancing the removal of bubbles in the water.

[0055] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
