Two-stage purification of natural gas from mechanical impurities with parallel-connected filter elements

摘要

The utility model relates to a gas supply, in particular to the purification of natural gas, and can be used in the composition of gas control points in the two-stage purification filter elements connected in parallel. The object of this utility model is to reduce specific metal housing a two-stage gas cleaning plant, connected in parallel with the filter elements. The problem is solved in that the two stage treatment of natural gas with parallel interconnected filter elements having a possibility of unilateral joining the inlet and outlet fittings by the first cover, wherein the two massive flat lid with openings along their perimeter excluded in its construction, as well as bolts and nuts, tightening them hermetically together, by placing in a common housing first and second cleaning stages with the necessary number of parallel of interconnected filtering elements. Using the proposed two-stage gas cleaning installations, allows: 1. Reduce the specific metal casing by removing two massive flat lids with holes at the periphery thereof, as well as bolts and nuts, tightening sealingly between these covers, by disposing in a common housing first and second cleaning steps with the required amount in parallel interconnected filter elements. 2. Reduce the area for placing the first and second treatment steps, due to their arrangement in one casing instead of two, and the connecting pipeline exceptions, as compared with existing analogue. 1 n.p.f. 1 yl.
