[0002] At present, the high-temperature liquid pipeline filtration in the coal tar deep processing and petrochemical industries all use a basket-type filter method to filter out particulate matter in the liquid phase to prevent particulate matter from clogging chemical equipment such as conveying pumps and heat exchangers. Then, a mutual backup and mutual use method is used to switch and clean the filter to achieve the purpose of shutdown and maintenance. The advantage of this filtration method is simple operation; the disadvantages are: first, the maintenance cycle is long, and the switching operation needs to be carried out slowly in a high-temperature environment, and then the water is diverted for cooling and cleaning; second, the safety and reliability are poor. Once the switching valve fails, the system needs to be shut down for maintenance.
