The dirt separator is a component widely used in petrochemical process pipeline. Its function is to prevent the impurities in the pipeline medium from entering the transmission equipment or precise parts, so as to cause production failure or affect the quality of products. The dirt separator is installed on the main water supply pipe at the user’s entrance, as well as at the entrance of heat source (cold source), heat (cold) equipment, water pump and regulating valve. Its structural forms are Y-type, tapered, right-angle and high-pressure. Its main materials are carbon steel, stainless acid-resistant steel, manganese vanadium steel, cast iron and malleable iron. The inner filter has copper mesh and stainless acid-resistant steel wire mesh.
Brief introduction of dirt separator
I. Function and use
The function of the dirt separator is to remove and filter the impurities and dirt in the pipeline, keep the water quality in the system clean, reduce resistance, protect equipment and prevent pipeline blockage.
II. Equipment structure and working principle
According to the national standard figure R406, the structure of the dirt separator can be divided into three types: horizontal through dirt separator, horizontal angle through dirt separator and vertical through dirt separator. The features of this filter are that the filter screen is improved from galvanized wire mesh specified in the original standard drawing to special stainless steel filter mesh. In the dirt separator, the water flow enters the cylinder from the inlet, the water flow filtered through the filter outflows from the outlet, and the dirt settles at the bottom of the dirt separator and is discharged through sewage discharge.
III. Installation and use
The dirt separator should generally be set in front of the inlet pressure regulating device of the heating system or the inlet of each equipment. Straight-through dirt separator is installed in horizontal pipeline, angle-pass degreaser can be installed in right-angle turning pipeline, and the arrow direction on the shell must be consistent with the direction of water flow. Regular discharge of pollutants should be carried out during operation.
