Description

Technical Field

[0001] The invention relates to the technical field of absorption tower auxiliary equipment, and in particular to a defoaming agent adding device for an absorption tower. Background Art

[0002] The absorption tower is a reaction vessel, with the middle part being the spray absorption part (absorption zone), the bottom being the reaction pool (oxidation crystallization zone), and the top being the demister part (demist zone). The spray part includes four groups of spray devices, which are divided into four layers. Each slurry circulation pump corresponds to a group of spray devices. The circulation pump extracts the limestone slurry from the reaction pool and sends it to the spray main pipe and double-head nozzle; the reaction pool is a large container where oxidation, precipitation, and crystallization reactions are carried out; after the spray section, the demister at the top of the absorption tower removes water droplets from the flue gas.

[0003] The slurry in the absorption tower will produce foam, causing the slurry in the absorption tower to emerge from the overflow pipe, but the liquid level of the absorption tower has not reached the overflow level. Therefore, when the foam is serious, it may cause a large differential pressure in the demister and ash accumulation in the pipe section at the flue gas inlet of the absorption tower.

[0004] At present, when the absorption tower foam overflows, the first thing to do is to notify the maintenance staff to check and clear the air holes in the overflow pipe to destroy the siphon conditions. The overflow phenomenon can also be eliminated by temporarily stopping a circulating pump. Desulfurization and defoaming agents can also be added to eliminate the bubbling phenomenon. However, when the absorption tower is bubbling, if the defoaming agent is not added in time manually, there will be loss in the process of pouring from the defoaming agent barrel into the measuring cup and then pouring it into the siphon breaking port or the absorption tower sump. When the absorption tower is not bubbling seriously, there is no need to add a large amount of defoaming agent. The dosage control is not accurate, which leads to waste. The defoaming agent concentration is very high, and it is directly added without dilution, and it adheres to the overflow pipe and ditch, which leads to waste. Summary of the invention

[0035] Example 1

[0036] Reference Figure 1 to Figure 7 , which is the first embodiment of the present invention, provides a defoaming agent adding device for an absorption tower, the device comprising:

[0037] The stirring mechanism 100 includes a motor 101, a jacket 102 fixedly connected to the output end of the motor 101, and an inner rod 103 slidably connected to the bottom end of the jacket 102, a stirring blade 104 is fixedly connected to the outer side of the inner rod 103, a converging component 105 is arranged on the outer side of the inner rod 103, a guide component 106 is adapted and installed inside the inner rod 103, and a closing component 107 is arranged at the bottom end of the inner rod 103;

[0038] The main structure 200 includes a metering tank 201, a support column 202 fixedly connected to the bottom end of the metering tank 201, and a cover 203 mounted on the top end of the metering tank 201 by bolts, an adjusting component 204 is arranged inside the cover 203, and an output component 205 is mounted on the bottom end of the metering tank 201.

[0039] Specifically, a support frame 101a is provided at the bottom end of the motor 101, a support plate 101b is fixedly connected to the top end of the support frame 101a, and the motor 101 is adapted to be installed on the top end of the support plate 101b.

[0040] Furthermore, the conduit component 105 includes a conduit plate 105a fixedly connected to the outside of the inner rod 103, and a sealing ring 105b fixedly connected to the outside of the conduit plate 105a;

[0041] The sealing ring 105b is made of rubber and is installed on the outside of the busbar 105a in an upward tilted design. The busbar 105a is designed to be concave in the center, and the center of the busbar 105a is designed to be flush with the opening 103b.

[0042] Furthermore, the guide component 106 includes a second spring 106a fixedly connected to the inner rod 103, and a guide block 106b fixedly connected to one end of the second spring 106a, the guide block 106b is slidably connected to the inner rod 103, and one end of the guide block 106b is set to be hemispherical.

[0043] Preferably, the sealing component 107 includes a sealing block 107a fixedly connected to the bottom end of the inner rod 103, and a plug 107b fixedly connected to the bottom end of the sealing block 107a.

[0044] It should be noted that the outer side of the metering tank 201 is fixedly connected with a side plate 201a, the bottom end of the side plate 201a is fixedly connected with a right-angle plate 202b, and the support frame 101a is fixedly connected to the top end of the side plate 201a.

[0045] Preferably, a side plate 201a is fixedly connected to the outer side of the metering tank 201, a right-angle plate 202b is fixedly connected to the bottom end of the side plate 201a, and the support frame 101a is fixedly connected to the top end of the side plate 201a.

[0046] Preferably, the adjusting component 204 includes a fixing sleeve 204a fixedly connected to the inside of the cover 203, and an oblique guide groove 204b formed on the inner wall of the fixing sleeve 204a, and one semicircular end of the guide block 106b is located inside the oblique guide groove 204b.

[0047] First, the defoaming agent concentrate is stored in the liquid storage hopper 203a, and then the motor 101 is started and water is supplied to the metering tank 201 through the water inlet pipe 203b. The operation of the motor 101 will drive the outer sleeve 102 and the inner rod 103 to rotate. At this time, since the guide block 106b is located in the inclined guide groove 204b, the inner rod 103 is driven to slide downward in the outer sleeve 102 under the guidance of the inclined guide groove 204b and stretch the first spring 103a until the guide block 106b slides to the bottom end of the fixed sleeve 204a. At this time, the centrifugal force of the rotation of the inner rod 103 will drive the guide block 106b to extend from the inside of the inner rod 103. At this time, the guide block 106b will fit the bottom end of the fixed sleeve 204a to limit the tension of the first spring 103a, ensuring that the inner rod 103 cannot be reset after sliding downward. When the motor 101 is stopped, the inner rod 103 stops rotating and the guide block 106b is driven to reset under the elasticity of the second spring 106a. One end of the guide block 106b is hemispherical and under the pulling force of the first spring 103a, the inner rod 103 is driven to slide upward and reset.

[0048] Through the above, when the motor 101 is started, the inner rod 103 will slide down and then continue to rotate. After the inner rod 103 slides down, the convergence plate 105a and the sealing ring 105b will be driven to slide down synchronously. The sliding of the sealing ring 105b can prompt the bottom of the liquid storage bucket 203a to open, thereby prompting the defoaming agent solution inside the liquid storage bucket 203a to flow into the metering tank 201 and mix with the water flowing into the metering tank 201, thereby achieving the dilution of the defoaming agent solution. The rotating stirring blade 104 can improve the mixing effect of the defoaming agent solution and water.

[0049] When the motor 101 stops, the inner rod 103 will reset, which will prompt the sealing ring 105b to reset and fit against the bottom of the liquid storage bucket 203a, thereby sealing the liquid storage bucket 203a. At the same time, the inclined design of the sealing ring 105b can ensure that the sealing ring 105b is squeezed and fit against the bottom of the liquid storage bucket 203a for higher sealing performance.

[0050] When the inner rod 103 slides down to dilute the defoaming agent liquid, it will drive the plug 107b at the bottom of the sealing block 107a to seal the bottom tube 205a, ensuring that the liquid inside the metering tank 201 is effectively mixed. When the dilution is completed and the motor is stopped, the plug 107b at the bottom of the sealing block 107a will slide up and open, ensuring that the liquid can be used normally.

[0051] In summary, when the defoamer stock solution needs to be diluted and used, it is only necessary to start the motor 101 and add water to the metering tank 201 to quickly complete the dilution of the defoamer stock solution, and the addition of the defoamer stock solution can be automatically stopped after the motor 101 is stopped. When it is needed for a second use, the motor 101 can be started again without the need for a startup process, which is more efficient and convenient as a whole compared to the traditional method of manual dilution.

[0052] Example 2

[0053] Reference Figure 1 to Figure 7 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: a first spring 103a is fixedly connected to the top of the inner rod 103, an opening 103b is provided on the outer side of the inner rod 103, an inner cavity 103c is provided inside the inner rod 103, and a round hole 103d is provided on the outer side of the inner rod 103;

[0054] The top end of the first spring 103a is fixedly connected to the inner top end of the outer sleeve 102, the opening 103b, the inner cavity 103c and the circular hole 103d are connected, and the circular hole 103d is opened obliquely downward.

[0055] When the motor 101 is started, the defoaming agent liquid and water entering the metering tank 201 will flow on the surface of the sealing ring 105b. Since the sealing ring 105b is not squeezed at this time, the sealing ring 105b is not tilted. Under the guidance of the sealing ring 105b, the defoaming agent liquid and water will gradually flow into the manifold 105a, and finally flow into the inner cavity 103c through the opening 103b.

[0056] Due to the continuous rotation of the manifold 105a, the defoaming agent solution and water in the manifold 105a will be initially mixed and then flow into the inner cavity 103c. Then, under the centrifugal force of the rotation of the inner rod 103, the liquid in the inner cavity 103c will flow into the metering tank 201 through the circular hole 103d. As the inner rod 103 continues to rotate, the position of the liquid flowing out through the circular hole 103d will be continuously adjusted, thereby further improving the effect and efficiency of liquid mixing, ensuring that after the motor 101 stops, the liquid inside the metering tank 201 has been mixed and can be directly used.

[0057] In summary, when using the defoamer stock solution and diluting it, the operator only needs to start the motor 101 and add water to the metering tank 201 to quickly realize the defoamer dilution process. After the dilution is completed, stop the motor 101, and the system will automatically interrupt the addition of the defoamer stock solution. If it needs to be used again, simply restart the motor 101 without repeating the cumbersome startup procedure. Compared with the traditional manual dilution method, this operation method greatly improves efficiency and convenience.

[0058] In addition, the device is equipped with two different preliminary mixing systems, which, combined with the rotating stirring blades 104, can significantly improve the quality and speed of liquid mixing. This ensures that after the motor 101 stops working, the liquid in the metering tank 201 has been fully mixed and can be used for subsequent operations at any time, further improving the working efficiency of the device.

[0059] Example 3

[0060] Reference Figure 1 , Figure 2 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the bottom end of the metering tank 201 is fixedly connected with a bottom pipe 205a, an output pump 205b adapted to be installed at one end of the bottom pipe 205a, and a connecting pipe 205c installed at the other end of the output pump 205b.

[0061] After the defoaming agent stock solution is diluted, the output pump 205b is started to spray the defoaming agent through the bottom pipe 205a and the connecting pipe 205c to the siphon breaking port to eliminate the foam, thereby ensuring the normal operation of the absorption tower as a whole.
