Description

Technical Field

[0001] The invention relates to the technical field of cooling water treatment, in particular to cooling water treatment equipment using PBTC for circulation. Background Art

[0002] PBTC is a new generation of phosphonic acid, which is a leading low-phosphorus corrosion and scale inhibitor and is now widely used in industrial production. PBTC has a low phosphorus content. Due to its structural characteristics of phosphonic acid and carboxylic acid, it has good scale and corrosion inhibition performance, which is better than commonly used organic phosphonic acid. Especially at high temperature, its scale inhibition performance is far better than commonly used organic phosphonic acid. It can improve the solubility of zinc, has good chlorine oxidation resistance, and good compound synergy.

[0003] PBTC products are widely used in circulating cooling water systems. PBTC has good resistance to calcium carbonate and calcium phosphate scale. PBTC also has good high temperature resistance, oxidation resistance, and chlorine resistance stability, and has good dispersion performance for high turbidity and high iron circulating water.

[0004] Therefore, when the cooling water is circulated, a corresponding amount of PBTC solution needs to be added to its inner end. During the injection process, since the amount of cooling water processed each time is different, there are the following problems:

[0005] First, the traditional method of adding PBTC solution is to carry PBTC solution through a quantitative cup, measure the amount of cooling water currently injected into the water tank, obtain the corresponding amount of PBTC solution through solubility calculation, and then pour the corresponding PBTC solution into it through the quantitative cup for mixing. Since the amount of cooling water in the treatment process is different in most cases, multiple calculations are required for each addition of PBTC solution, which greatly increases the workload of addition, and it is easy to have errors in the final calculation results due to careless observation.

[0006] Second, during the addition process, the corresponding amount of PBTC solution is poured into the cooling water from top to bottom through a quantitative cup. When the amount of cooling water is large, the PBTC solution at the top takes a certain amount of time to reach the bottom, resulting in uneven dissolution of the PBTC solution in the upper and lower areas of the cooling water in a short period of time. It takes a long time of stirring to achieve uniform dissolution, which affects the dissolution efficiency of the PBTC solution in the cooling water.

[0007] In order to address the above problems, there is an urgent need for cooling water treatment equipment that uses PBTC for circulation. Summary of the invention

[0013] As a further improvement of the technical solution, an insert block is provided at the bottom end of the bottom tube, and a slot for plugging and fitting with the insert block is provided at the top end of the top column.

The vertical pipe is connected to the inner end of the inner chamber, and the top end of the vertical pipe extends upward to the top port position of the cooling water tank, and the top end of the vertical pipe is connected to a quantitative tank. The top end of the quantitative tank protrudes outward to the outside of the top end of the cooling water tank, so as to introduce the PBTC solution outside the cooling water tank into the inner end of the inner chamber.

[0015] As a further improvement of the present technical solution, the collar is fixed to the inner side of the cooling water tank through the vertical pipe and the metering tank, the top column is located inside the collar and rotates, and there is an angle between two adjacent vertical pipes at different heights, and the interval angle range is 0-90 degrees.

[0019] As a further improvement of the technical solution, a return spring is connected between the inner wall of the connecting tube at the end of the sealing column away from the liquid storage chamber plate.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the cooling water treatment equipment using PBTC for circulation, the floating plate sequentially moves to the outer side of the collar at corresponding heights, and the liquid inlet assembly of the collar that passes through is connected, so that all the PBTC solutions at the inner end of the liquid storage cavity plate at the corresponding position are discharged to the inner end of the liquid storage assembly, and the PBTC solutions are gathered at different heights at the inner end of the cooling water tank through the liquid storage assemblies at different positions. Meanwhile, the floating plate's upward movement height is proportional to the amount of cooling water injected, and the corresponding amount of liquid storage assemblies that gather the PBTC solutions is proportional thereto. The amount of PBTC solutions finally thrown out is also positively correlated with the amount of cooling water.

[0033] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-Figure 2 As shown, a cooling water treatment device using PBTC for circulation is provided, comprising a cooling water tank 10 and a stirring assembly 20 arranged at the inner end of the cooling water tank 10, the stirring assembly 20 comprising a stirring shaft 220 and a servo motor 210 driving the stirring shaft 220 to rotate, and a plurality of liquid storage assemblies 230 are sequentially connected to the bottom end of the stirring shaft 220, and each liquid storage assembly 230 is used to gather equal amounts of PBTC solution on different horizontal surfaces at the inner end of the cooling water tank 10;

[0036] A collar 30 is provided on the outside of each liquid storage component 230, and a liquid storage cavity plate 310 for pre-storing PBTC solution is provided on one side of the collar 30. A liquid inlet component is connected between the liquid storage cavity plate 310 and the inner end of the liquid storage component 230, and a pressure component is provided between the liquid inlet component and the liquid storage cavity plate 310. The pressure component protrudes from the outside of the collar 30, and a floating plate 130 is provided at the inner end of the cooling water tank 10. The inner side of the floating plate 130 is sleeved on the outer side of the collar 30. Under the buoyancy of the cooling water, pressure is applied upward to the protruding positions of the pressure components at different heights in turn, so that the pressure components are displaced to conduct the liquid inlet component, forming a liquid guide channel, and the PBTC solution pre-stored at the inner end of the liquid storage cavity plate 310 at different heights is introduced into the inner end of the liquid storage component 230;

[0037] A plurality of drainage cavity plates 240 for draining liquid are arranged in an array on the outer side of the liquid storage component 230. The drainage cavity plates 240 are connected to the inner end of the liquid storage component 230, and the PBTC solution gathered in the liquid storage component 230 is discharged to a cooling horizontal plane of a corresponding height by utilizing the centrifugal force generated by the rotation of the liquid storage component 230. At the same time, the floating plate 130 moves at a height adapted to the amount of cooling water injected into the inner end of the cooling water tank 10, and correspondingly connects the liquid inlet components and the liquid storage component 230 at different heights, and utilizes the centrifugal force generated by the rotation to discharge the total amount of PBTC solution at the inner end of the liquid storage component 230, adapted to the corresponding amount of cooling water.

[0038] During specific use, during the process of adding PBTC solution to cooling water, when cooling water is not injected into the inner end of the cooling water tank 10, the float 130 moves down to the bottom position under the action of its own gravity. At this time, the inner ends of each liquid storage chamber plate 310 are pre-stored with the same amount of PBTC solution, and are not connected to the inner end of the liquid storage component 230. Subsequently, the cooling water to be treated is pumped into the inner end of the cooling water tank 10 through the liquid inlet pump 110 on one side of the cooling water tank 10. When the inflowing cooling water contacts the bottom position of the float 130, the buoyancy generated by the cooling water is used to drive the float 130 to move vertically upward along the inner end of the cooling water tank 10, and when passing the outer position of the collar 30, it is connected to the float 130. The pressure component on the outside of the collar 30 contacts and applies thrust to it, thereby the liquid inlet component discharges all the PBTC solution stored in the inner end of the liquid storage chamber plate 310 to the inner end of the liquid storage component 230. After the water injection work is completed, the buoyancy generated by the cooling water drives the floating plate 130 to its position above the water surface. In this process, the floating plate 130 sequentially corresponds to the outer position of the collar 30 at the height, and conducts the liquid inlet component of the collar 30 passing through, and discharges all the PBTC solution in the inner end of the liquid storage chamber plate 310 at the corresponding position to the inner end of the liquid storage component 230. The PBTC solution is gathered at different heights of the inner end of the cooling water tank 10 through the liquid storage components 230 at different positions.

[0039] The stirring shaft 220 is driven to rotate by the servo motor 210, and the stirring shaft 220 drives each liquid storage component 230 to rotate synchronously. The liquid storage component 230 uses the drainage cavity plate 240 set at its bottom to form a vortex in the cooling water to stir the entire cooling water. At the same time, the drainage cavity plate 240 is connected to the inner end of the liquid storage component 230. The centrifugal force generated during the rotation of the liquid storage component 230 throws the PBTC solution gathered at its inner end outward along each drainage cavity plate 240, so that different positions and heights in the cooling water can contact the PBTC solution within a short rotation time. , and mix it evenly, thereby improving the mixing efficiency of the PBTC solution. At the same time, the upward movement height of the floating plate 130 is proportional to the amount of cooling water injected, and the amount of the corresponding liquid storage component 230 that gathers the PBTC solution is proportional to it. The amount of PBTC solution finally thrown out is also positively correlated with the amount of cooling water, that is, the corresponding amount of PBTC solution is automatically adapted to different water injection amounts, without the need to perform multiple water and solution volume measurements, thereby improving the cooling water treatment efficiency. After completing the treatment work, the treated cooling water is pumped out of the cooling water tank 10 through the drainage pump 120 and the drainage pipe 121.

[0040] In addition, the liquid storage component 230 includes a top column 231 and a bottom tube 232 arranged at the bottom end of the top column 231. A liquid storage gap 233 for PBTC solution aggregation is reserved between the inner side of the bottom tube 232 and the outer side of the liquid storage component 230. The liquid storage gap 233 maintains conduction with the drainage cavity plate 240.

[0041] Furthermore, an insert block 234 is provided at the bottom end of the bottom tube 232 , and a slot 235 which is plugged and matched with the insert block 234 is provided at the top end of the top column 231 .

[0042] Furthermore, an inner chamber 314 is opened at the inner end of the liquid storage chamber plate 310, and a vertical pipe 311 is arranged at the top end of the liquid storage chamber plate 310. The vertical pipe 311 is connected to the inner end of the inner chamber 314, and the top end of the vertical pipe 311 extends upward to the top port position of the cooling water tank 10, and the top end of the vertical pipe 311 is connected to the quantitative tank 312. The top end of the quantitative tank 312 protrudes outward to the outside of the top end of the cooling water tank 10, so as to introduce the PBTC solution outside the cooling water tank 10 into the inner end of the inner chamber 314.

[0043] Specifically, the collar 30 is fixed to the inner side of the cooling water tank 10 through the vertical pipe 311 and the quantitative tank 312, the top column 231 is located inside the collar 30 and rotates, and there is an angle between two adjacent vertical pipes 311 at different heights, and the interval angle range is 0-90 degrees.

[0044] In addition, the liquid inlet component includes a connecting tube 330 that is connected to the inner end of the inner chamber 314 and a drainage tube 340 that is connected to the connecting tube 330. The connecting tube 330 and the drainage tube 340 form a Y-shaped channel. The bottom end of the drainage tube 340 is connected to a vertical tube. The bottom end of the vertical tube extends into the inner end of the liquid storage gap 233 and remains connected to the inner end of the liquid storage gap 233.

[0045] Furthermore, the pressure assembly includes a V-shaped plate 320 and a sealing column 321 connected to the middle position of the side of the V-shaped plate 320. The V-shaped plate 320 slides along the outer side of the liquid storage chamber plate 310. The inner end of the inner chamber 314 is slidably connected to a pressure plate 313. The cross-sectional size of the pressure plate 313 is consistent with the cross-sectional size of the inner end of the inner chamber 314, and the sealing column 321 is fixedly connected to the pressure plate 313. The sealing column 321 passes through the liquid storage chamber plate 310 and extends to the inner end of the connecting tube 330. In an unstressed state, its end is located at the connecting position of the Y-shaped channel to form a blockage.

[0046] Furthermore, the side of the V-shaped plate 320 away from the sealing column 321 is a V-shaped structure, and the side protrudes out of the outside of the ring 30.

[0047] In addition, a return spring 322 is connected between the end of the sealing column 321 and the inner wall of the connecting tube 330 away from the liquid storage chamber plate 310 .

[0048] When used specifically, during the PBTC solution supply process, the PBTC solution to be treated is first introduced into the inner end of the quantitative tank 312, such as Figure 6As shown, the outer side of the quantitative tank 312 is provided with a graduated groove for quantitative measurement, and a valve is provided at the inner end thereof. In order to ensure that the amount of PBTC solution finally entering the inner end of the inner chamber 314 is constant, when conducting the liquid, the valve can be closed in advance by observing the alignment position of the liquid and the graduated groove. When the corresponding liquid level is reached, the valve is opened again, so that a constant amount of PBTC solution is directly introduced into the inner end of the inner chamber 314 along the vertical pipe 311;

[0049] Depend on Figure 3 As shown, as the cooling water continuously flows into the inner end of the cooling water tank 10, the buoyancy generated will drive the floating plate 130 to move up along the cooling horizontal plane. At this time, the floating plate 130 will slide along the outer sides of each collar 30, and the sides of each V-shaped plate 320 protrude from the outer side of the collar 30. Therefore, when the floating plate 130 passes through the outer side of the collar 30, it will contact the outer side of the V-shaped plate 320, and use the generated buoyancy to convert it into a thrust to push the V-shaped plate 320, driving the V-shaped plate 320 to slide close to the liquid storage chamber plate 310. Figure 6-Figure 7 As shown, during this process, the V-shaped plate 320 will drive the sealing column 321 to extend deep into the inner end of the connecting tube 330, and squeeze the return spring 322 to make it in a compressed state, and the end of the sealing column 321 will be away from the connection between the connecting tube 330 and the drainage tube 340, so that the connecting tube 330 and the drainage tube 340 remain connected, and the sealing column 321 will simultaneously drive the pressing plate 313 to slide along the inner wall of the inner chamber 314 while moving, pushing the PBTC solution located at the inner end of the inner chamber 314, so that it flows into the inner end of the connecting tube 330 along the inner chamber 314, and is introduced into the inner end of the liquid storage gap 233 through the drainage tube 340 and the vertical pipe, and the cross-sectional size of the pressing plate 313 is consistent with the cross-sectional size of the inner chamber 314, and there is no gap between the two, and the PBTC solution stored at the inner end of the inner chamber 314 is completely pushed into the inner end of the connecting tube 330 during the pushing process;

[0050] It is worth noting that Figure 4-Figure 5 As shown, each liquid storage component 230 is plugged and matched with each other through the plug block 234 and the slot 235, and is sequentially spliced ​​to form stirring columns of different heights. This is because the PBTC solutions with different cooling water volumes are adapted differently. During the treatment process, the PBTC solution needs to be matched according to the cooling water volume to be treated. Not only does it need to change the amount of PBTC solution introduced into the inner chamber 314, but it also needs to match the corresponding number of spliced ​​liquid storage components 230, so that the release height of the PBTC solution corresponding to the different cooling water volumes is adapted, that is, the more cooling water volume, the higher the water surface height, and the more corresponding liquid storage components 230 are spliced;

[0051] In order to further improve the adaptability range of PBTC solution, Figure 2As shown, during the installation of the liquid storage chamber plate 310 and the vertical pipe 311, it is necessary to adjust the position of the adjacent liquid storage chamber plates 310, and reserve an angle of 0-90 degrees between the two. On the one hand, fulcrums are set at different positions of the ring 30 to improve its support stability. On the other hand, it prevents the vertical pipe 311 from being set too close, resulting in the quantitative tank 312 at the top being set too densely, affecting the subsequent addition work. In actual use, the reserved angle is inversely proportional to the number of liquid storage components 230 spliced ​​together. The more liquid storage components 230 are spliced ​​together, the smaller the corresponding reserved angle is.

[0052] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
