FIELD: gas extractive industry, possible use for cleaning low pressure gas, extracted from methane-coal well during its completion and operation.
SUBSTANCE: device includes cylindrical body with input tangential branch pipe in its lower part, with lid and bottom, in which axial channels are made. Connecting positions are provided on lid and bottom for mounting pipeline and locking-controlling armature, and also vortex generator. Inside the body positioned coaxially and serially along its height in downward direction are, interconnected, cover, funnel and figure element. Frame is positioned in circular space, formed by internal surface of body and external surface of cover, with possible interaction with the latter. Frame is concentrically mounted inside the body and interacts with the lid. Vortex generator is positioned in the upper part of circular space, formed by internal surface of cover and external surface of frame. Figure element is made in form of cylindrical spiral, coiling direction of which coincides with direction of gas movement. Area of through cross-section in circular space between adjacent coils of cylindrical spiral is selected to be equal to total area of through cross-sections in vortex generator. Upper part of frame is made with possible interaction with upper flange on the body and has external circular shelf, lower end part of which is made with circular recess, having concave curvilinear surface, for example, in form of anchor ring. Filtration element is made of material based on fluorocarbon polymer. Frame is made in form of barrel, and filtration element - in form of hollow cylinder, mounted on external surface of frame. Internal channel of input tangential branch pipe is positioned between adjacent coils of cylindrical spiral.
EFFECT: increased efficiency of cleaning of low-pressure gas from mechanical admixtures and drop liquid on the mouth of methane-coal product well.
