[0002] In the operation of the limestone wet flue gas desulfurization system, the absorption tower often produces a lot of foam due to various reasons. If these foams are not handled in time, they will cause the liquid level in the absorption tower to fluctuate, affect the gas-liquid mass transfer effect, and may even cause false liquid level, overflow and other problems, seriously affecting the normal production.

[0003] The traditional method of adding defoaming agents mainly relies on the operating personnel to manually carry the defoaming agent barrel to the side of the absorption tower pit, pour it into the absorption tower pit, and pump it into the absorption tower through the absorption tower pit pump. However, manual judgment of the foam situation is easily affected by subjective factors, resulting in inaccurate defoaming agent dosage. When a large amount of foam is suddenly generated, it may also be impossible to add the defoaming agent in time. This needs to be improved. Summary of the invention

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0026] Example 1 is the first example of the present invention, which provides a method for intelligently dosing defoaming agent in an absorption tower. The method includes detecting the foam content inside the absorption tower by a foam sensor, and feeding it back to a processor inside the controller, and detecting the required content of the defoaming agent concentrated solution by the processor; and controlling the dilution pump by the controller to transport the defoaming agent concentrated solution inside the storage bin to the inside of the dilution tank.

[0027] Among them, the foam sensor can detect the foam generation inside the absorption tower in real time, so that the processor inside the controller can detect the foam generation in real time. When the foam reaches the zero limit value, the release pump can be controlled immediately to prevent overflow due to excessive foam.

[0028] Furthermore, the content of the defoaming agent is calculated by a liquid level detector; by opening the clean water valve, clean water is injected into the dilution tank and the mixed solution is stirred evenly by a stirrer, and the liquid level detection also detects the injection amount of clean water during the injection of clean water; finally, the diluted defoaming agent mixed solution is injected into the absorption tower through the delivery valve, and the mixed solution is stirred evenly by the stirrer inside the absorption tower, thereby achieving the defoaming effect.

[0029] Among them, the dilution pump is used to inject the concentrated solution of defoaming agent into the dilution tank, and the liquid level detector is used to detect the content of the concentrated solution inside the dilution tank, and send the concentrated solution content information to the controller, so that the controller can control the injection of clean water of the corresponding content to dilute the concentrated solution.

[0030] In addition, the injection pump is used to inject the diluted solution into the absorption tower, so that the solution inside the absorption tower cannot generate a large number of bubbles, and the agitator is used to stir the mixed solution evenly.

[0031] Furthermore, the foam sensor is used to detect the foam content inside the absorption tower and feed back the foam content information to the processor inside the controller to facilitate the calculation of the required defoaming agent concentrated solution content.

When the processor inside the control receives the foam content inside the absorption tower, the dilution liquid is injected into the absorption tower through the delivery pump, so that the foam inside the absorption tower is cleared, thereby achieving the defoaming effect, which can effectively prevent the problem of adding too much and too much defoaming agent, and can prevent emergencies.

[0037] Preferably, the concentrated solution inside the storage component 101 is diluted by the dilution component 102, and then the dosing component 105 is controlled by the control component 104. When foam is generated inside the absorption tower body 101a, the dosing component 105 is controlled to dose the diluted solution, thereby achieving defoaming treatment of the solution inside the absorption tower.

[0042] Preferably, the dilution valve 102c is first opened, and the concentrated solution in the storage bin 101c is injected into the dilution tank 102d through the dilution pump 102b, and then the dilution valve 102c is closed. After closing the dilution valve 102c, corresponding clean water is injected from the clean water inlet 102f according to the injection amount of the concentrated solution, and then the mixed liquid is mixed through the second agitator 102e to obtain a defoaming agent dilution liquid.

[0043] Furthermore, the cleaning assembly 103 includes a cleaning port 103a disposed at the bottom end of the storage bin 101c, and a drainage port 103b disposed at the bottom end of the dilution tank 102d.

[0045] In summary: the concentrated defoaming agent solution in the storage bin 101c is injected into the dilution tank 102d through the dilution pump 102b, and then the corresponding clean water is added. Then, the concentrated defoaming agent solution and the clean water are mixed through the operation of the second mixer, and then the dilution of the defoaming agent is completed. Then, the operation of the dosing component 105 is controlled by the control component 104, so that the dosing component 105 injects the diluted dilution liquid into the absorption tower.

[0048] Furthermore, the dispensing component 105 includes a dispensing pump 105a disposed on the dilution tank 102d, and a dispensing pipe 105b disposed on the dispensing pump 105a.

[0049] The delivery pump 105a is used to deliver the dilution liquid in the dilution tank 102d into the absorption tower, and the delivery pipe 105b is used to transport the injection dilution liquid.

[0050] In summary: the foam content inside the absorption tower body 101a is detected by the foam sensor 104a, and then the information is transmitted to the processing inside the controller 104c, so that the controller 104c controls the delivery pump 105a to inject the diluted foaming agent inside the dilution tank 102d into the absorption tower. After the dilution solution is injected, the concentrated foaming agent solution is delivered to the dilution tank 102d through the dilution pump 102b, and then the corresponding clean water is injected through the liquid level detector 104b, so that the dilution liquid is replenished, thereby avoiding the inaccurate dosage of the defoaming agent and the failure to deliver the defoaming agent in time.
