When the catalyst suspension continuously enters the cylinder 101 to reduce the concentration of the suspension, the data detected by the concentration sensor 604 is lower than a threshold value, the PLC 703 starts the first electromagnetic three-way valve 601 and the second electromagnetic three-way valve 602 to work again by using the relay 704, the working first electromagnetic three-way valve 601 closes the suspension extraction pipe 503 and opens the clear liquid extraction pipe 502 again, the working second electromagnetic three-way valve 602 closes the pressure sensor 605 and opens the concentration sensor 604 again to switch the turbid liquid or clear liquid extracted by the diaphragm pump 501, so that the extraction of clear liquid and turbid liquid in the concentration filter can be completed by using only one diaphragm pump 501, the equipment cost is saved, the concentration of the turbid liquid extracted can be effectively controlled, and the concentration effect of the catalyst suspension is improved.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that various modifications and substitutions are possible within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
