Technical Field

The invention relates to a filter, in particular to a hydrocyclone separation filter, and belongs to the fields of petrochemical industry and coal chemical industry.

Background

Many media of petrochemical and coal chemical plants contain solid particles such as coke particles, and during the operation of the plants, the solid particles easily cause blockage and abrasion of equipment such as tower plates, valves, pipelines and the like, so that the solid particles must be removed. There are three approaches currently used, one is to filter out solid particles with a filter, one is to remove solid particles with a hydrocyclone, or the other is to combine the two. In the actual operation process, the filter is used only, and the filter screen of the filter is easy to block due to high solid particle content, so that the operation period is short. By using the hydrocyclone alone, large particles can be easily removed, but small particles still enter the system, and the solid particles are not completely removed. And the mode of combining the filter and the hydrocyclone separator needs to use two sets of devices, so that the occupied space is large, and the investment cost is high.
