Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization absorption towers, in particular to a pH meter measuring device for the solution in a desulfurization absorption tower. Background Art

[0002] The desulfurization absorption tower is mainly used for flue gas desulfurization. Due to its high desulfurization rate, wide applicability of coal quality, mature process technology, long stable operation cycle, small influence of load change, large flue gas treatment capacity and other characteristics, it is widely used in large and medium-sized thermal power plants and has become the leading process technology for flue gas desulfurization in thermal power plants at home and abroad.

[0003] The absorption tower uses limestone solution. The control of the pH value has a very important influence on the absorption speed of sulfur dioxide and the dissolution degree of limestone. For example, reducing the pH value can improve the dissolution degree of limestone, but in a lower pH value environment, it is not conducive to the absorption of sulfur dioxide. While increasing the pH value can promote the absorption of sulfur dioxide, it reduces the dissolution degree of limestone. Therefore, in actual work, while ensuring the effective dissolution of limestone, the absorption of sulfur dioxide needs to reach the specified standard. Usually, the pH value is maintained between 4.8 and 5.8, and maintaining the pH value requires regular detection.

[0004] At present, the detection adopts the drainage and external discharge method. This method requires welding a drainage pipe pile about 1.5 meters above the bottom of the absorption tower, draining the slurry in the absorption tower through a pipeline, opening a hole in the connecting pipeline to install a pH measurement probe for measurement, and discharging the drained slurry through the pipeline to the absorption tower sump, and then pumping it back to the absorption tower through the sump pump.

[0005] This measurement method has relatively large losses and energy consumption. The slurry flows out of the absorption tower and is discharged into the absorption tower sump through pipelines and ditches, filling the absorption tower sump with slurry in a short time, causing the sump pump to start frequently. At the same time, a large amount of slurry will evaporate after being drained, forming acid mist in the air, corroding all surrounding equipment such as the absorption tower wall, steel frame, and flue, resulting in great environmental pollution.

[0036] Next, the present utility model will be described in detail with reference to the schematic diagrams.

[0037] Embodiment 1

[0038] Referring to Figure 1 , an overall structural schematic diagram of a pH meter measuring device for the solution in a desulfurization absorption tower is provided, as shown in Figure 1-4 , a pH meter measuring device for the solution in a desulfurization absorption tower, comprising:

[0039] Absorption tower 100;

[0040] The detection part 200 includes a measured component 201 installed on the absorption tower 100.

[0041] Furthermore, the measured component 201 includes a carrier member 201a that penetrates the absorption tower 100 and extends into its interior, and a monitoring member 201b that is movably connected and used for pH monitoring of the solution in the desulfurization absorption tower.

[0042] Furthermore, the carrier member 201a includes an outer cylinder 201a-1, an open cylinder 201a-2 is movably connected inside the outer cylinder 201a-1, a small handwheel 201a-3 is threadedly connected to one end of the outer cylinder 201a-1, a conical surface 201a-4 is provided on the inner side of the other end of the outer cylinder 201a-1, and a conical block 201a-5 adapted to the conical surface 201a-4 is provided at the end of the open cylinder 201a-2.

[0043] Specifically, the outer cylinder 201a-1 penetrates the absorption tower 100, and the outer cylinder 201a-1 is fixed to the absorption tower 100 by welding. The end of the outer cylinder 201a-1 with the conical surface 201a-4 is located in the absorption tower 100;

[0044] An internal thread one is provided at the end of the outer cylinder 201a-1 away from the conical surface 201a-4, and a pipe thread one is provided on the outer side of the open cylinder 201a-2 at the open side. The pipe thread one is threadedly connected to the internal thread one. By the thread characteristics, when the open cylinder 201a-2 rotates, the open cylinder 201a-2 will make a linear displacement along the thread direction of the internal thread. When the conical surface of the conical block 201a-5 of the open cylinder 201a-2 fits the conical surface 201a-4, the outer cylinder 201a-1 is closed, and a sealing gasket is attached to the conical block 201a-5 to play a sealing role;

[0045] Further, liquid inlets 201a-6 are equidistantly arranged on the surface of the open cylinder 201a-2 near one end of the conical block 201a-5, and a large handwheel 201a-7 is sleeved on the other end of the open cylinder 201a-2. The large handwheel 201a-7 is installed on the open cylinder 201a-2 through a locking nut 201a-8.

[0046] Specifically, a retaining piece is arranged outside the open cylinder 201a-2. The large handwheel 201a-7 is sleeved into the open cylinder 201a-2 from the open end, and the large handwheel 201a-7 abuts against the retaining piece. Then, the large handwheel 201a-7 is locked by the locking nut 201a-8. Therefore, when rotating the open cylinder 201a-2, it is only necessary to rotate the large handwheel 201a-7.

[0047] Further, the monitoring member 201b includes a rod body 201b-1 inserted into the open end of the open cylinder 201a-2. A cavity 201b-2 is provided inside the rod body 201b-1. An O-ring 201b-3 is embedded and installed on the outer side of one end of the rod body 201b-1. A detection sensor 201b-4 is threadedly installed at one end of the rod body 201b-1, and the other end of the detection sensor 201b-4 is electrically connected to a signal output line 201b-5.

[0048] Specifically, an internal thread 2 is provided on the inner side of the open end of the open cylinder 201a-2, and a pipe thread 2 is provided on the outer side of one end of the rod body 201b-1. During installation, the end of the rod body 201b-1 with the detection sensor 201b-4 is inserted from the open side of the open cylinder 201a-2. When the pipe thread 2 contacts the internal thread 2, the rod body 201b-1 is rotated to complete the installation of the rod body 201b-1. The other end of the signal output line 201b-5 penetrates through the rod body 201b-1 and extends to the outside to be connected to the signal output line of the display device. The detection sensor 201b-4 detects the pH value of the solution inside the absorption tower 100, and the detected result is transmitted to the display device through the signal output line 201b-5. The display device displays the detected pH value for intuitive viewing.

[0049] Operation process: When detecting the pH value, rotate the large handwheel 201a-7 clockwise. After the rotation of the large handwheel 201a-7, it drives the rotation of the open cylinder 201a-2. Due to the thread characteristics, the open cylinder 201a-2 will move inward along the thread direction of the first internal thread while rotating. During the inward movement of the open cylinder 201a-2, the conical block 201a-5 will move away from the conical surface 201a-4. When the liquid inlet 201a-6 moves out of the outer cylinder 201a-1, the solution inside the absorption tower 100 will enter through the liquid inlet 201a-6. After entering, the solution will contact the detection sensor 201b-4. The detection sensor 201b-4 detects the pH value of the solution inside the absorption tower 100. The detected result is transmitted to the display device through the signal output line 201b-5, and the display device shows the detected pH value. This structure can achieve single detection and real-time monitoring, eliminating unnecessary steps, making the detection more convenient, reducing the running time of the sump pump of the desulfurization absorption tower 100 at the current stage, significantly reducing the start-stop frequency and failure rate of the sump pump of the absorption tower 100, saving a large amount of maintenance costs, and at the same time reducing the working intensity of maintenance personnel;

[0050] During measurement, no large amount of slurry is discharged, so the problem of acid mist formation in the sump area of the absorption tower 100 is solved, avoiding the corrosion of peripheral equipment of the absorption tower 100 by the acid mist and extending the service life of the equipment;

[0051] When not detecting or maintaining the detection sensor 201b-4, rotate the large handwheel 201a-7 counterclockwise to drive the outward displacement of the open cylinder 201a-2, thereby making the conical block 201a-5 fit with the conical surface 201a-4 to play a role in sealing the outer cylinder 201a-1. Further, rotate the rod body 201b-1 counterclockwise. When the second internal thread is not connected to the second pipe thread, the rod body 201b-1 can be pulled out, and the detection sensor 201b-4 can also be taken out.

[0052] Embodiment 2

[0053] Refer to Figure 5 , what is different from the first embodiment in this embodiment is that the detection part 200 in this embodiment further includes:

[0054] A liquid return assembly 202, connected below the actual measurement assembly 201;

[0055] It includes a liquid receiving pot 202a, the upper end of the liquid receiving pot 202a is communicated with a liquid guide pipe 202b, and the bottom of the liquid receiving pot 202a is communicated with a liquid return pipe 202c. The other end of the liquid return pipe 202c is vertically upward and communicated with the inside of the absorption tower 100. The outside of the liquid guide pipe 202b is rotatably connected with a tightening sleeve 202d.

[0056] Specifically, an oil leakage hole is provided at the bottom end of the outer cylinder 201a-1, and a threaded connection ring is provided at the bottom of the outer cylinder 201a-1. The tightening sleeve 202d is screwed onto the threaded connection ring, so that the liquid guide pipe 202b is communicated with the oil leakage hole. When the rod body 201b-1 is drawn out, the residual solution located inside the opening cylinder 201a-2 will flow out along the inner wall of the outer cylinder 201a-1. When it reaches the position of the oil leakage hole, it will enter the liquid receiving pot 202a from the oil leakage hole through the liquid guide pipe 202b. A liquid level sensor is provided in the liquid receiving pot 202a, and the liquid level sensor is connected to a controller. The controller is provided with a threshold value. When the liquid volume is higher than the set threshold value, the solution in the liquid receiving pot 202a will be returned to the absorption tower 100 through the liquid return pipe 202c by means of a water pump (the water pump is installed on the liquid return pipe 202c). This structure can process the solution brought out when the opening cylinder 201a-2 is taken out. On the one hand, it reduces the waste of the solution, and on the other hand, it can avoid the problem that the solution produces acid mist to corrode the equipment.

[0057] All other structures are the same as those in Embodiment 1.

[0058] Embodiment 3

[0059] Referring to Figure 6-8 , what is different about this embodiment from the above embodiments is that the pH meter measuring device for the solution in the desulfurization absorption tower of this embodiment further includes:

[0060] The port wire harness protection part 300 is installed at one end of the actual measurement component 201, and it includes a mounting seat component 301, a rotating seat component 302 rotatably connected to the mounting seat component 301, and an adjusting component 303 for driving the angle adjustment between the rotating seat component 302 and the mounting seat component 301;

[0061] The mounting seat component 301 includes a rotating disk 301a. A perforation 301b is provided at the axis center of the rotating disk 301a, and a fixing frame one 301c is fixed on one side of the rotating disk 301a. A wire threading cylinder one 301d is fixed inside the fixing frame one 301c.

[0062] Further, the rotating seat component 302 includes a fixing frame two 302a rotatably arranged at one end inside the fixing frame one 301c, and a wire threading cylinder two 302b is fixed inside the fixing frame two 302a.

[0063] Specifically, both ends inside of the wire threading cylinder one 301d and the wire threading cylinder two 302b are arranged in an arc structure. When there is an angle between the wire threading cylinder one 301d and the wire threading cylinder two 302b, it can reduce the damage to the insulating layer of the signal output wire 201b-5 caused by the bending of the signal output wire 201b-5 due to the port knife surface.

[0064] Further, the adjusting component 303 includes a first rotating block 303a and a rotating piece 303b. A connecting rod 303c is rotatably connected above the rotating piece 303b. One end above the connecting rod 303c is rotatably connected to a second rotating block 303d. A rotating rod 303e is disposed through the second rotating block 303d. A knob 303f is fixed at one end of the rotating rod 303e. A rotating shaft 303g is disposed through the first rotating block 303a. The rotating shaft 303g is elastically connected to the rotating rod 303e through an elastic member 303h. And a thread 303i is provided on the surface of one end of the rotating shaft 303g.

[0065] Specifically, an internal thread hole is provided on the first rotating block 303a. The thread 303i on the rotating shaft 303g is threadedly connected to the internal thread hole. When the signal output line 201b-5 needs to be bent during the installation process, first rotate the knob 303f. When the knob 303f rotates, it drives the rotating rod 303e to rotate. One end of the rotating rod 303e is fixedly connected to one end of the elastic member 303h. Therefore, while the rotating rod 303e rotates, it drives the rotating shaft 303g to rotate through the elastic member 303h. When the rotating shaft 303g rotates, due to the thread characteristics, it makes a linear displacement along the thread direction of the thread hole, thereby driving the second fixing frame 302a to rotate and form an angle with the first fixing frame 301c. By adjusting the angle, the signal output line 201b-5 can be in the optimal bending range, avoiding the problem of breakage caused by excessive bending and folding, and reducing the maintenance cost.

[0066] Further, the elastic member 303h includes a cylinder 303h-1. A movable disk 303h-2 is movably connected in the cylinder 303h-1. The movable disk 303h-2 divides the interior of the cylinder 303h-1 into a left chamber 303h-3 and a right chamber 303h-4. Springs 303h-5 are provided in both the left chamber 303h-3 and the right chamber 303h-4.

[0067] Specifically, strip-shaped grooves are equidistantly provided at the middle position inside the cylinder 303h-1. A protrusion that slides in the strip-shaped groove is fixed on the outer side of the movable disk 303h-2, which can play a limiting role. And the center of one side of the movable disk is fixed to one end of the rotating shaft 303g. A through hole for the rotating shaft 303g to pass through is provided on one end of the cylinder 303h-1 corresponding to one side of the rotating shaft 303g. Furthermore, under the action of the spring 303h-5, mutual elastic stretching can be achieved, playing an elastic connection role and avoiding the problem of damage to the signal output line 201b-5 caused by rigid fixation.

[0068] All other structures are the same as those in Embodiment 2.
