SEPARATOR-LOCK TRAP AND METHOD OF ITS APPLICATION Russian patent published in 2014 - IPC B01D45/12 B01D47/10 

FIELD: process engineering.

SUBSTANCE: invention relates to cleaning of gas from fluid and mechanical impurities and can be used in oil-and-gas, petrochemical and chemical industries and power production. Lock trap comprises at least horizontal tank with inlet and outlet fluid connection pipes. Said tank accommodates sand collection and removal device composed by at least two swirlers interconnected via pipeline system. Tank body top section accommodates at least one vertical cyclone scrubber including at least vertical cylindrical body communicated with tank chamber, gas-fluid flow feed pipe and purified gas discharge pipe. Inlet pipe is arranged so that its axis is perpendicular to scrubber vertical axis while outlet pipe axis is parallel with scrubber lengthwise vertical axis and, preferably, aligned therewith. Outlet pipe cross-section is communicated with flow swirler inlet, said swirler being composed by helical surface arranged between cylindrical body inner surface and outlet pipe outer surface. Outlet pipe inlet accommodates at least two conical belts with their bases directed downward. Scrubber vertical tank bottom accommodates the flow-anti-swirling device composed of spatial structure of several ribs. Top edges of said ribs accommodate with the help of hollow cylinder the device designed to prevent fluid carry-out with purified gas flow and composed of, preferably, hollow cone with its base facing said ribs.

EFFECT: higher efficiency.
