[0020] Assembly of the scrubber shell: First, prepare the scrubber shell 1, and set the air inlet 2 and the inspection port 10 on its side, install the sewage outlet 3 at the bottom of the scrubber shell 1, and ensure that the sewage outlet 3 is connected with the inside of the scrubber shell 1.

[0021] Connection of the oil-liquid separation tank: On the other side of the drain outlet 3, the oil-liquid separation tank 13 is connected to the bottom of the scrubber housing 1 through a pipeline, and the scrubber pump 11 is installed above the oil-liquid separation tank 13, and ensure that the scrubber pump 11 is connected to the inside of the oil-liquid separation tank 13.

[0022] Installation of the spray head: In the middle of the scrubber housing 1, two groups of upper and lower spray heads 4 are installed. The spray heads 4 are connected to the scrubber pump 11 through the liquid delivery pipeline 9 to ensure that the scrubbing liquid can be smoothly transported to the spray heads 4 for spraying.

[0023] Installation of filter plate: A filter plate 8 is installed inside the scrubber housing 1 between two groups of spray heads 4. The filter plate 8 is composed of a support frame 82, a palm fiber board 81 and a ceramic particle filling layer 83 to ensure that impurities in the coal gas can be effectively filtered.

[0024] The support frame 82 is the main structure of the filter plate 8, which is responsible for carrying the palm fiber board 81 and the ceramic particle filling layer 83, ensuring the stability and firmness of the entire filter plate; the palm fiber board 81 is made of palm tree fiber and has good adsorption and filtration properties; the palm fiber board 81 is located above the support frame 82, as the first layer of the filter plate, it is mainly responsible for preliminary filtration and adsorption. It can effectively remove most of the solid particles and suspended matter in the gas; the ceramic particles used in the ceramic particle filling layer 83 are a hard, wear-resistant and high-temperature resistant material; the ceramic particle filling layer 83 is located inside the middle groove of the support frame 82, as the second layer of the filter plate, it is mainly responsible for deep filtration and purification, it can further remove the tiny particles and harmful substances in the gas through its tiny pores and surface area, the groove bottom plate in the middle of the support frame 82 adopts a mesh structure, which means that it has a certain permeability and strength, this structure allows the filtered gas and liquid to pass through, while supporting the ceramic particle filling layer above.

[0025] Installation of demister and gas equalizing plate: demister 5 is installed inside the upper end of the scrubber housing 1, and gas equalizing plate 7 is installed on the scrubber housing 1 between the lower part of demister 5 and the spray head 4. Gas equalizing plate 7 includes a circular plate body 71 and vent holes 72 uniformly protruding to ensure that the gas is evenly distributed in the scrubber.

[0026] The main function of the air equalizing plate 7 is to evenly distribute the passing gas. Since the air vents 72 are evenly raised and installed downward, this ensures that when the gas passes through, the airflow will be evenly dispersed into each air vent, avoiding excessive concentration or loss of local airflow, thereby achieving uniform distribution of airflow. The raised structure of the air vents 72 installed downward can effectively prevent these liquids from dripping or splashing through the air vents. The raised air vents 72 can increase the overall structural strength of the air equalizing plate. This design allows the plate body 71 to be more stable when subjected to gas pressure or impact, reducing performance degradation caused by deformation or damage; the downward raised structure of the air vents 72 can reduce the resistance of the gas when it passes through. This is because the raised structure makes the flow path of the gas smoother when passing through the air vents, reducing the friction between the gas and the plate body, thereby reducing energy consumption.

[0027] Installation of other components: An air outlet 6 is provided at the top of the scrubber housing 1 so that the treated gas can be discharged smoothly, and an adjustable air inlet valve is provided at the air inlet 2 on the side of the scrubber housing 1 to control the amount of gas entering. A slag discharge port is provided at the bottom of the oil-liquid separation tank 13, and a detachable filter screen is installed at the slag discharge port to handle oil stains and impurities.

[0028] Operation of coke oven gas scrubber

[0029] Gas entry: Coke oven gas is introduced into the scrubber housing 1 through the gas inlet 2.

[0030] Spraying and filtering: Start the gas washing pump 11, and deliver the washing liquid in the oil-liquid separation tank 13 to the spray head 4 through the liquid delivery pipe 9 to spray and wash the coal gas. At the same time, the coal gas is filtered by the filter plate 8 to remove impurities therein.

[0031] Demisting and gas equalization: The coal gas after spraying and filtration enters the demister 5 to remove the water mist therein, and then passes through the gas equalization plate 7 to ensure that the coal gas is evenly distributed in the gas scrubber.

[0032] Gas discharge: The treated gas is discharged through the gas outlet 6 and enters the subsequent production process.

[0033] Discharge and circulation: During the scrubbing process, the sewage and oil generated enter the oil-liquid separation tank 13 through the discharge port 3. In the oil-liquid separation tank 13, the oil is separated and discharged through the overflow port, while the washing liquid at the bottom is continuously circulated through the scrubbing pump 11.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
