Abstract
Description
Technical Field
[0001] The invention relates to the technical field of wet desulfurization, and in particular to a desulfurization slurry pH measuring device. Background Art
[0002] As we all know, lime or limestone desulfurization uses lime or limestone slurry to absorb sulfur dioxide in flue gas in an absorption tower to obtain a mixture of calcium sulfite and calcium sulfate, which is then sent to an oxidation tower and oxidized by air. The resulting calcium sulfate slurry is centrifuged and washed to obtain finished calcium sulfate. The advantage of this method is that the absorbent is inexpensive and easy to obtain, so it is widely used in industry. The pH meter consists of a sensor and a secondary meter. It can be equipped with three composite or two composite electrodes to meet various usage locations. It is equipped with pure water and ultrapure water electrodes and is suitable for pH measurement of water with a conductivity of less than 3μs / cm.
[0003] The pH value detection device is a commonly used device in the current vulcanization system. The problems existing in the prior art are: the mud is directly sprayed on the pH electrode, which damages the pH electrode and causes inaccurate monitoring of the pH electrode. Summary of the invention
[0004] In view of this, the present invention provides a desulfurization slurry pH measuring device, the main purpose of which is to maintain the accuracy of desulfurization slurry pH monitoring.
[0005] In order to achieve the above object, the present invention mainly provides the following technical solutions:
[0006] The present invention provides a desulfurization slurry pH measuring device, which comprises: a tank body and a straight pipe;
[0007] A PH electrode is installed on the top wall of the tank body, and an overflow port is provided on the upper end side of the tank body, and the overflow port is higher than the detection end of the PH electrode;
[0008] The straight tube is arranged in the tank body, and extends along the diameter direction of the radial section circle of the tank body. Both ends of the straight tube are respectively connected to the arc tube, and the circumference of the central axis of the arc tube is concentric with the radial section circle of the tank body.
[0009] The purpose of the present invention and the solution to its technical problems can be further achieved by adopting the following technical measures.
[0010] Optionally, it also includes a partition, which is arranged in the tank body and is used to separate the tank body into an upper tank body and a lower tank body. The partition is evenly distributed with a plurality of through holes, and the straight tube and the arc tube are arranged in the lower tank body.
[0011] Optionally, a flushing water pipe is also included, and the outlet end of the flushing water pipe points to the detection end of the pH electrode.
[0012] Optionally, a spiral nozzle is also included, and the spiral nozzle is installed at the outlet end of the flushing water pipe.
[0013] Optionally, it also includes a slurry supply pipe and an intermediate pipe, the slurry supply pipe passes through the side wall of the tank body and is connected to the middle pipe wall of the straight pipe, one end of the intermediate pipe is connected to the flushing water pipe, and the other end is connected to the slurry supply pipe, the intermediate pipe is provided with a check valve, the inlet of the check valve faces the flushing water pipe, and the outlet of the check valve faces the slurry supply pipe.
[0014] Optionally, the arc tube extends upward in a spiral shape by one sixth of the pitch.
[0015] Optionally, the edges of the upper surface and the lower surface of the partition are designed with rounded corners.
[0016] Optionally, it also includes a sewage pipe, which is connected to the lower end side of the tank body and is equipped with a sewage valve.
[0017] By means of the above technical solution, the present invention has at least the following advantages:
[0018] When the device is in operation, the desulfurization slurry flows out along the straight pipe and the arc pipe in turn. Because the circumference of the central axis of the arc pipe is concentric with the circumference of the radial section of the tank body, the desulfurization slurry is sprayed out along the radial circumference of the tank body, causing the liquid level in the tank body to rise steadily. When the liquid level rises to the detection end of the PH electrode, the PH electrode detects the desulfurization slurry, and as the slurry level continues to rise, the slurry flows out of the tank body from the overflow port.
[0019] In the above process, the mud liquid level in the tank rises gently, and the impact of the mud fluid on the pH electrode is relatively gentle, which avoids damage to the pH electrode, extends the service life of the pH electrode, and ensures the long-term accuracy of desulfurization mud pH monitoring.

DETAILED DESCRIPTION
[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.
[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0027] like Figure 1 As shown, an embodiment of the present invention provides a desulfurization sludge pH measuring device, which includes: a tank body 1 and a straight pipe 2;
[0028] A PH electrode 3 is installed on the top wall of the tank body 1, and an overflow port is provided on the upper end side of the tank body 1, and the overflow port is higher than the detection end of the PH electrode 3;
[0029] The straight tube 2 is arranged in the tank body 1, and the straight tube 2 extends along the diameter direction of the radial cross-section circle of the tank body 1. The two ends of the straight tube 2 are respectively connected to the arc tube 4, and the circumference of the central axis of the arc tube 4 is concentric with the radial cross-section circle of the tank body 1.
[0030] The working process of the desulfurization slurry pH measuring device is as follows:
[0031] When the device is in operation, the desulfurized sludge flows out along the straight pipe 2 and the arc pipe 4 in turn. Since the circumference of the central axis of the arc pipe 4 is concentric with the circumference of the radial section of the tank body 1, the desulfurized sludge is sprayed out along the radial circumference of the tank body 1, so that the liquid level in the tank body 1 rises steadily. When the liquid level rises to the detection end of the PH electrode 3, the PH electrode 3 detects the desulfurized sludge. As the sludge liquid level continues to rise, the sludge flows out of the tank body 1 from the overflow port.
[0032] In the above process, the mud liquid level in the tank 1 rises gently, and the mud fluid has a gentle impact on the pH electrode 3, thereby avoiding damage to the pH electrode 3, extending the service life of the pH electrode 3, and ensuring the long-term accuracy of the desulfurization mud pH monitoring.
[0033] Specifically, the pH electrode 3 includes two detection ends, which are fixed on a mounting base on the top wall of the tank body 1 .
[0034] like Figure 1 and Figure 2 As shown, in a specific embodiment, it also includes a partition 5, which is arranged in the tank body 1 and is used to separate the tank body 1 into an upper tank body 1 and a lower tank body 1. The partition 5 is evenly distributed with a plurality of through holes 6, and the straight tube 2 and the arc tube 4 are arranged in the lower tank body 1.
[0035] Specifically, if there is no partition 5, because the muddy water flow sprayed by the arc tube 4 flows along the circumferential direction of the tank body 1, it is easy to form a vortex on the liquid surface of the tank body 1. In this way, with the rise of the muddy liquid surface, the following situation may occur: because the center of the vortex liquid surface is lower than the edge of the vortex liquid surface, the edge of the vortex has already contacted the overflow port, but the middle of the vortex has not yet contacted the detection end of the pH electrode 3, thereby affecting the accuracy of pH detection;
[0036] In the present embodiment, the density of the through holes 6 in the middle of the partition 5 is greater than the density of the through holes 6 at the periphery of the partition 5. Due to the presence of the partition 5, when the liquid level in the tank body 1 rises to the partition 5, the height difference between the edge of the vortex and the middle of the vortex is reduced due to the obstruction of the periphery of the partition 5, so that the mud liquid surface further approaches the horizontal plane, so that the mud liquid surface can definitely contact the detection end of the pH electrode 3 before the mud overflows.
[0037] like Figure 1 As shown, in a specific embodiment, a flushing water pipe 7 is also included, and the outlet end of the flushing water pipe 7 points to the detection end of the pH electrode 3.
[0038] In this embodiment, specifically, when the device is running, the PH electrode 3 detection process and the PH electrode 3 flushing process are performed alternately. During the PH electrode 3 detection process, the flushing water pipe 7 valve is closed and the slurry supply pipe 9 valve is opened; during the PH electrode 3 flushing process, the flushing water pipe 7 valve is opened and the slurry supply pipe 9 valve is closed. The outlet end of the flushing water pipe 7 points to the detection end of the PH electrode 3, and the sprayed flushing water washes the mud adhered to the surface of the detection end of the PH electrode 3, thereby maintaining the sensitivity of the detection end of the PH electrode 3 and ensuring the accuracy of the PH detection value.
[0039] like Figure 1 As shown, in a specific embodiment, a spiral spray head 8 is also included, and the spiral spray head 8 is installed at the outlet end of the flushing water pipe 7.
[0040] In this embodiment, specifically, with the detection end of the PH electrode 3 as the center, multiple spiral nozzles 8 are arranged in a circle, the spray directions of the multiple spiral nozzles 8 point to the detection end of the PH electrode 3, and the multiple spiral nozzles 8 spray water synchronously to improve the cleaning efficiency of the detection end of the PH electrode 3.
[0041] like Figure 1As shown, in a specific embodiment, it also includes a slurry supply pipe 9 and an intermediate pipe 10. The slurry supply pipe 9 passes through the side wall of the tank body 1 and is connected to the middle pipe wall of the straight pipe 2. One end of the intermediate pipe 10 is connected to the flushing water pipe 7, and the other end is connected to the slurry supply pipe 9. The intermediate pipe 10 is provided with a check valve 11. The inlet of the check valve 11 faces the flushing water pipe 7, and the outlet of the check valve 11 faces the slurry supply pipe 9.
[0042] In this embodiment, specifically, during the process of flushing the pH electrode 3, the valve of the slurry supply pipe 9 is closed, and the valve of the flushing water pipe 7 is opened. While a part of the flushing water cleans the detection end of the pH electrode 3, the other part of the flushing water flushes the slurry supply pipe 9, the straight pipe 2 and the arc pipe 4 in sequence through the intermediate pipe 10;
[0043] During the detection of the PH electrode 3 , the valve of the flushing water pipe 7 is closed, the valve of the slurry supply pipe 9 is opened, and the check valve 11 prevents the mud solution from entering the flushing water pipe 7 to prevent the mud solution from violently impacting the PH electrode 3 .
[0044] like Figure 1 and Figure 3 As shown, in a specific embodiment, the arc tube 4 extends upward in a spiral shape by one sixth of the pitch.
[0045] In this embodiment, specifically, one end of the straight tube 2 is fixedly connected to the first arc tube 4, and the other end of the straight tube 2 is fixedly connected to the second arc tube 4. The spiral directions of the first arc tube 4 and the second arc tube 4 are the same, and the first arc tube 4 and the second arc tube 4 respectively extend upward in a spiral shape by one-sixth of the pitch. When it is necessary to thoroughly clean the mud adhered to the inner wall of the tank body 1, when the flushing water is sprayed along the first arc tube 4 and the second arc tube 4, it can flush the inner wall of the tank body 1 above the straight tube 2, so as to facilitate thorough cleaning of the inner wall of the tank body 1.
[0046] like Figure 1 and Figure 4 As shown, in a specific embodiment, the edges of the upper surface and the lower surface of the partition 5 are designed with rounded corners.
[0047] In this embodiment, specifically, the edge of the partition 5 is designed with rounded corners, which can reduce the existence of sanitary dead corners in the tank body 1.
[0048] like Figure 1 As shown, in a specific embodiment, it also includes a sewage pipe 12, which is connected to the lower end side of the tank body 1, and the sewage pipe 12 is installed with a sewage valve 13.
[0049] In this embodiment, specifically, when the inner wall of the tank body 1 needs to be thoroughly cleaned, the operator can open the sewage valve 13 to discharge the sewage after flushing the inner wall of the tank body 1 .
[0050] Specifically, the overflow port is connected to the inlet of the overflow pipe 14 , and the outlet of the overflow pipe 14 and the outlet of the sewage pipe 12 extend to the overflow tank 15 respectively.
[0051] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
