[0002] Some industrial flue gases contain a large amount of carbon dioxide gas, and the emission of carbon dioxide is the main factor causing the greenhouse effect. Therefore, timely and efficient capture of carbon dioxide in flue gas will greatly alleviate the greenhouse effect. When capturing flue gas, a washing system, such as a water washing tower, is usually used;

[0003] The water scrubber, also known as a washing tower, is a gas purification treatment equipment, which mainly includes: air inlet, packing layer, water tank, spray assembly and other structural components.

[0004] For example, the invention patent with publication number CN108611127A specifically discloses a new type of filtering water washing tower, which strengthens the pipeline and improves its safety of use by using reinforced composite materials.

[0005] During the waste gas treatment process of the washing tower, since the waste gas contains a large amount of particulate matter, the particulate matter may cause blockage to the nozzle during long-term use. When the nozzle is blocked by particulate matter, if the gas pressure cannot flush the blockage, the nozzle will be completely blocked, thereby affecting the treatment of the waste gas. At this time, the nozzle needs to be cleaned. However, most of the current methods are to manually enter the tower body to disassemble and clean the nozzle, which makes cleaning inconvenient. Therefore, it is necessary to design a flue gas carbon capture water washing tower to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0009] Furthermore, the bracket is provided with an annular groove matched with the annular tube.

[0010] Furthermore, the water pipe passes through the bracket and is connected to the ring pipe.

[0011] Furthermore, a sealing block is fixedly installed on the water supply pipe, and an open groove matched with the sealing block is opened on the water washing tower.

[0012] Furthermore, a sealing gasket is provided at the contact position between the sealing block and the opening groove.

[0013] The beneficial effect of the present application is that a flue gas carbon capture water washing tower provided by the present application is connected to the first flange by bolts through the second flange, and then the water supply pipe is grasped to pull out and disassemble, thereby replacing the prior art of setting the nozzle inside the water washing tower, thereby simplifying the installation and replacement process.

The pipeline pump 22 is used to pressurize the cleaning liquid flowing thereto. A water pump 221 is fixedly installed at the water outlet end of the pipeline pump 22. The pipeline pump 22 is used to pump the cleaning liquid in the water tank 21. A water pipe 222 is fixedly installed at the water outlet end of the water pump 221. The water pipe 222 is used to transport the cleaning liquid for spraying.

[0027] At the same time, an exhaust pipe 42 is fixedly installed at the end of the exhaust port 12, and the exhaust pipe 42 is used to transport the gas. A purification mechanism 4 is fixedly installed on the end of the exhaust pipe 42 away from the water washing tower 1. The purification mechanism 4 includes a purifier 41 fixedly installed on the end of the exhaust pipe 42 away from the water washing tower 1. The purifier 41 is used to purify the gas in accordance with the emission process, and a fan 43 is fixedly installed at the gas outlet end of the purifier 41. The fan 43 is used to suck the gas. At the same time, a discharge tower 44 is fixedly installed at the gas outlet end of the fan 43, and the discharge tower 44 is used to discharge the purified gas to a high place.

[0028] When the flue gas carbon capture water washing tower 1 is in use, the exhaust gas enters the water washing tower 1 through the air inlet 11, and then the cleaning liquid in the water tank 21 is sucked into the water pipe 222 by the water pump 221, and sprayed onto the packing layer 14. Then, when the exhaust gas flows through the packing layer 14 area, it meets the cleaning liquid. At this time, the gas and the cleaning liquid in the packing layer 14 can be fully mixed. After the harmful gas in the exhaust gas is cleaned, it is separated into gas and liquid through the demisting layer 15 and discharged through the exhaust port 12.
