Description

Technical Field

[0001] This utility model relates to the field of waste gas desulfurization technology, and in particular to a desulfurization limestone activity detection device. Background Technology

[0002] Desulfurization limestone is a mineral whose main component is calcium carbonate, and it is widely used as an absorbent in flue gas desulfurization processes. Its basic principle is to grind limestone into a fine powder, mix it with water to form a slurry, and then spray it into the flue gas to react with sulfur dioxide, producing calcium sulfite and calcium sulfate, thereby removing sulfur dioxide. Before using desulfurization limestone, its activity needs to be tested, which necessitates the use of appropriate activity testing equipment.

Its core function is to evaluate the reactivity of limestone with sulfur dioxide in flue gas by simulating actual desulfurization conditions. This device typically includes a temperature control system, a stirring device, an automatic titration system, and a pH detection module. It can automatically complete sample processing, reaction process control, and data acquisition and analysis, thereby achieving high-precision and high-efficiency detection of limestone activity. The test results can be directly used to guide the optimization of desulfurization system operation, improve desulfurization efficiency, and reduce energy consumption.

[0004] Although existing desulfurization limestone activity testing devices can meet most testing needs, when the equipment is not in use or has been used for a long time, it is not possible to quickly and efficiently disassemble, clean, and store the infusion tubing.

A workbench (2) is fixedly connected to the top of the detector (1), and a reaction bottle (3) is placed on the workbench (2) for detection. A reaction bottle (3) is installed on the top of the workbench (2), and activity detection is performed through the reaction bottle (3). A bottle cap (4) is installed on the top of the reaction bottle (3), ensuring the sealing of the reaction bottle (3). An auxiliary tube (16) is fixedly connected to the middle of the bottle cap (4), through which hydrochloric acid solution flows into the reaction bottle (3).

Positioning blocks (11) are fixedly connected to both ends of the connecting tube (14) to prevent the moving ring blocks (5) from sliding out. Springs (10) are fixedly connected to both ends of the outside of the connecting tube (14). The elastic action of the springs (10) allows the moving ring blocks (5) to quickly return to their original position. The ends of the two springs (10) are fixedly connected to... Inside the two movable ring blocks (5); the fixing component includes multiple locking blocks (13), all of which are located inside the connecting tube (14). The locking blocks 13 securely fix the infusion tube 7 and the auxiliary tube 16. The two movable ring blocks (5) are slidably connected to the outside of the multiple locking blocks (13). The infusion tube (7) and the auxiliary tube (16) are both fixedly connected to a sleeve (12). The sleeve (12) is interlocked with the locking blocks (13). The locking blocks 13 are fixed to the sleeve 12, allowing the auxiliary tube 16 and the infusion tube 7 to be tightly connected.

[0036] Reference Figures 1-6The mixing mechanism includes a stirring assembly and a cleaning assembly. The stirring assembly includes a motor (19), which drives the rotating rod 20 to rotate. The motor (19) is fixedly connected to the top of the bottle cap (4). The output end of the motor (19) is fixedly connected to a rotating rod (20).

[0037] Reference Figures 1-7 The auxiliary tube (16) is fixedly connected to a plug rod (17), and the infusion tube (7) is provided with an insertion hole (18). The plug rod (17) and the insertion hole (18) are interlocked. By inserting the plug rod 17 into the insertion hole 18, the infusion tube 7 and the auxiliary tube 16 can be connected more tightly. The top of the bottle cap (4) is fixedly connected to a feeding hopper (9). Desulfurized limestone is fed into the feeding hopper 9. The feeding hopper (9) is fixedly connected to a motor (29) and driven by the motor. The output end of the motor (29) is fixedly connected to a metering column (28). The metering column (28) is used to quantify the desulfurized limestone. The metering column (28) is located inside the feeding hopper (9). The detector (1) is fixedly connected to one end of a detection tube (8). The detection tube (8) is fixedly connected to the outside of the detector. The other end is fixedly connected to a detector (25), which detects the pH value of the mixture to perform activity detection. The detector (25) is fixedly connected to a stop (26) on the outside, which allows the detector (25) to be placed on top of the bottle cap 4 when not in use, without hindering the operation of the stirring assembly. The bottle cap (4) has a groove (27) on the top, which is inserted into the groove 27 when the detector (25) is needed. The stop (26) is located on top of the bottle cap (4). The bottom of the detector (1) is fixedly connected to a base (30), which makes the device more stable. The infusion tube (7) is fixedly connected to a sealing ring (15), which prevents leakage during the delivery of hydrochloric acid. The auxiliary tube (16) is slidably connected inside the sealing ring (15).

[0038] Working principle: First, when it is necessary to connect the infusion tube 7 and the auxiliary tube 16, by moving the moving ring block 5 to both sides and squeezing the spring 10, the locking block 13 inside the connecting tube 14 will retract into the connecting tube 14. Then, insert the infusion tube 7 and insert the insertion rod 17 into the insertion hole 18 to secure it. Since there is a sealing ring 15 on the outside of the infusion tube 7 and the auxiliary tube 16, there will be no leakage. Then, release the hand, and due to the elasticity of the spring 10, the moving ring block 5 will quickly return to the center and squeeze the locking block 13, locking the locking block 13 into the sleeve 1 on the outside of the infusion tube 7 and the auxiliary tube 16. Inside 2, the infusion tube 7 and the auxiliary tube 16 are tightly and quickly snapped together; one end of the detection tube (8) is fixedly connected to the outside of the detector (1), and the other end of the detection tube (8) is fixedly connected to the detector (25). A stop block (26) is fixedly connected to the outside of the detector (25). A groove (27) is opened on the top of the bottle cap (4), and the stop block (26) is located on the top of the bottle cap (4); a base (30) is fixedly connected to the bottom of the detector (1), and a sealing ring (15) is fixedly connected to the outside of the infusion tube (7). The auxiliary tube (16) is slidably connected inside the sealing ring (15).

[0039] Secondly, before testing the activity of the desulfurized limestone, it is necessary to feed the desulfurized limestone into the hopper 9. The metering column 28 is rotated by starting the motor 29, and the fed desulfurized limestone can then be quantified. Hydrochloric acid is then fed into the infusion pipe 7 for reaction. After the infusion is complete, the motor 19 is started, at which time the rotating rod 20 will rotate, and drive the external stirring blade 21 to rotate, so as to fully stir the hydrochloric acid and desulfurized limestone. At the same time, the connecting rod 23 connected to the rotating rod 20 will also rotate, and the scraper 22 connected to the connecting rod 23 through the torsion spring 24 will also operate to scrape down and dilute the mixture remaining on the inner wall of the reaction bottle 3, so as to ensure the accuracy of the test.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
