[0002] In the field of carbon capture, absorbers are one of the most important equipment, which is responsible for capturing and treating carbon dioxide emitted from industrial processes. Absorbers react with carbon dioxide through chemical absorbents, thus separating it from the exhaust gas. However, absorbers may encounter some challenges during operation, one of which is the growth of algae.
[0003] Algae grow on the outside of the clean smoke pipe of the absorber, forming a biofilm that can easily block the clean smoke pipe opening, thus affecting the normal emission of gas in the absorber. Blockage of the clean smoke pipe will not only reduce the efficiency of the absorber, but may also lead to an increase in pressure in the absorber.
[0004] This may threaten the structural integrity of the absorber when the pressure inside the absorber increases, and in the long run, may cause damage or failure of the absorber. In addition, the increase in pressure may also cause safety issues, such as equipment explosion or leakage, which will not only pollute the environment, but also pose a threat to personnel safety.

[0010] Furthermore, a breeding layer is provided in the biodegradation chamber, and organisms are cultured in the breeding layer.
[0011] Furthermore, a channel is provided between the breeding layer and the side wall of the pipe opening of the clean smoke pipe.

[0032] like Figure 1 As shown, the present application provides an ultrasonic negative pressure cleaning device, and an embodiment of the ultrasonic negative pressure cleaning device is arranged at the clean smoke pipe 11 of the flue gas treatment tower 10, and the embodiment of the ultrasonic negative pressure cleaning device includes: a closed cover 20 and an ultrasonic negative pressure device. The closed cover 20 is arranged on the outside of the clean smoke pipe 11, and a avoidance hole for the pipe mouth of the clean smoke pipe 11 to pass through is arranged on the closed cover 20, and the side wall of the pipe mouth of the clean smoke pipe 11 is located in the closed cover 20. The ultrasonic negative pressure device is arranged on the outside of the closed cover 20, and the ultrasonic negative pressure device includes a negative pressure generator 31 and an ultrasonic generator 35, the negative pressure generator 31 is connected to the closed cover 20 through a first pipeline 32, and the ultrasonic generator 35 is connected to the closed cover 20 through a second pipeline 36.
[0033] The technical solution of this embodiment is applied, and the ultrasonic negative pressure cleaning device is arranged at the clean smoke pipe 11 of the flue gas treatment tower 10, and the ultrasonic negative pressure cleaning device includes: a closed cover 20 and an ultrasonic negative pressure device. The ultrasonic wave generated by the ultrasonic generator 35 enters the closed cover 20 through the second pipeline 36, and the cavitation effect generated by the ultrasonic wave in the liquid of the ultrasonic generator 35 forms tiny bubbles and implodes, releasing energy to destroy the algae on the side wall of the pipe mouth of the clean smoke pipe 11. In the process of destroying the algae on the side wall of the pipe mouth of the clean smoke pipe 11, the negative pressure generator 31 puts the closed cover 20 in a negative pressure environment through the first pipeline 32, so as to enhance the destruction effect of the ultrasonic wave, thereby inhibiting the formation and growth of the biofilm of the algae, so as to be able to remove the algae on the outside of the clean smoke pipe 11 of the absorption tower, avoid the algae from easily blocking the pipe mouth of the clean smoke pipe 11, and reduce the impact on the normal discharge of the gas in the absorption tower. Therefore, the technical solution of this embodiment effectively solves the problem that the algae in the related art easily blocks the pipe mouth of the clean smoke pipe. The flue gas treatment tower 10 is preferably an absorption tower.
[0034] like Figure 1 As shown, in order for the negative pressure generator 31 to extract the air in the sealed cover 20 to put the sealed cover 20 in a negative pressure environment, a first control valve 33 is provided on the first pipeline 32, and the first control valve 33 controls the on-off of the first pipeline 32. In order for the ultrasonic wave generated by the ultrasonic generator 35 to enter the sealed cover 20 through the second pipeline 36, a second control valve 37 is provided on the second pipeline 36, and the second control valve 37 controls the on-off of the second pipeline 36.
[0035] like Figure 1 As shown, in order to enhance the destructive effect of ultrasonic waves, a negative pressure detection element 34 is provided on the sealed cover 20, and the negative pressure detection element 34 is used to detect the negative pressure in the sealed cover 20. The ultrasonic negative pressure clearing device also includes a controller, and the negative pressure detection element 34 and the first control valve 33 are both connected to the controller.
[0036] like Figure 1 As shown, the closed cover 20 is provided with a ventilation door 41, which can be opened and closed. The ultrasonic negative pressure cleaning device also includes a biodegradation chamber 42 arranged outside the closed cover 20. When the ventilation door 41 is opened, the organisms in the biodegradation chamber 42 enter the side wall of the pipe opening of the clean smoke pipe 11 in the closed cover 20. After the ventilation door 41 is opened, air enters the closed cover 20, and the organisms in the biodegradation chamber 42 can enter the closed cover 20 for further biological degradation of algae, thereby achieving the purpose of completely removing the algae on the side wall of the pipe opening of the clean smoke pipe 11.
[0037] like Figure 1 As shown, in order for the organisms to survive in the biodegradation chamber 42 , a breeding layer 43 is provided in the biodegradation chamber 42 , and the organisms are cultured in the breeding layer 43 .
[0038] like Figure 1 As shown, in order to facilitate the movement of the cultured organisms in the culture layer 43 to the algae area on the side wall of the pipe opening of the clean smoke pipe 11, a channel is provided between the culture layer 43 and the side wall of the pipe opening of the clean smoke pipe 11.
[0039] like Figure 1 As shown, the ultrasonic negative pressure cleaning device also includes a chlorophyll detector 51 disposed in the closed cover 20 and facing the clean smoke pipe 11, and the ultrasonic negative pressure cleaning device also includes a controller, and the chlorophyll detector 51, the first control valve 33 and the second control valve 37 are all connected to the controller. The chlorophyll detector 51 can monitor the concentration of algae on the clean smoke pipe 11 in real time. The controller automatically adjusts the opening of the first control valve 33 and the opening of the second control valve 37 according to the feedback of the chlorophyll detector 51, so as to adjust the negative pressure in the closed cover 20 and the output power of the ultrasonic generator 35.
[0040] like Figure 1 As shown, in order to monitor the concentration of algae on the clean smoke pipe 11 more accurately, there are multiple chlorophyll detectors 51, and the multiple chlorophyll detectors 51 are arranged at intervals.
[0041] The present application also provides an ultrasonic negative pressure removal method for algae, which is implemented by the above-mentioned ultrasonic negative pressure removal device. The ultrasonic negative pressure removal method for algae includes the following steps:
[0042] The concentration of algae on the side wall of the pipe opening of the clean smoke pipe 11 is checked in real time by the chlorophyll detector 51;
[0043] The negative pressure in the sealed cover 20 and the power output by the ultrasonic generator 35 are controlled according to the concentration.
[0044] Since the ultrasonic negative pressure cleaning device can solve the problem in the related art that algae easily clog the pipe opening of the smoke cleaning pipe, the ultrasonic negative pressure cleaning method of algae using the ultrasonic negative pressure cleaning device can solve the same technical problem. The ultrasonic generator 35 generates ultrasonic waves in the range of 20kHz to 300kHz, and the power adjustment range is in the range of 50W to 800W.
[0045] Further, the step of controlling the negative pressure in the closed cover 20 and the power output by the ultrasonic generator 35 according to the concentration includes:
[0046] When the concentration of algae is greater than or equal to 16 μg / L, the current negative pressure in the closed cover 20 and the power output by the ultrasonic generator 35 are increased;
[0047] When the concentration of algae is less than 16 μg / L, the current negative pressure in the enclosure 20 and the power output by the ultrasonic generator 35 are maintained.
[0048] In this way, according to the real-time feedback from the chlorophyll detection device, the controller can automatically adjust the negative pressure in the closed cover 20 and the output power of the ultrasonic generator 35 to achieve the best control effect.
[0049] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0050] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0051] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
