FIELD: gas producing industry; gaseous throttling separators. ^ SUBSTANCE: the invention is pertaining to the field of gas producing industry, in particular, to the gaseous throttling separators and may be used in any industry for clearing of gaseous mixtures from a dropping liquid and mechanical impurities and-or for throttling of gases with preservation of the temperature of the inlet gases and with a partial heating. The separator contains a body with bottoms. The body is made out of two coaxially mounted cylindrical shells, the upper of which has a smaller diameter, than the lower. The lower edge of the upper shell is located in the upper part of the lower shell. In the upper part of the separator there are a tangential connecting pipe for a gas feeding and an axial connecting pipe for withdrawal of the gas. The separator is supplied with a liquid phase rejector, the upper edge of which is located so, as to form an annular slot between it and the lower edge of the upper shell. At that the lower part of the liquid phase rejector is made so, as to form an annular chamber for accumulation of the slime, for withdrawal of which the separator has a connecting pipe mounted in the lower shell. Coaxially with the body there is a throttling device made in the form of a pipe connected with the gas withdrawal connection pipe. In the lower part of throttling device made in the form of a pipe there is at least one pair of either coaxially located radial holes or inclined holes located at the similar angle to the axis of the pipe. It is expedient to locate the holes in a chessboard order. Inside the pipe there is a cylindrical adjusting device with a capability of the axial motion for overlapping at least one pair of the indicated holes. Usage of the separator allows to increase a degree of efficiency of the gas cleaning at the expense of organization of the trapped liquid phase with mechanical impurities downward flow, that besides will exclude its secondary entrainment, will ensure heating of gases at the separator outlet and in result the uninterrupted operation of the separator and the following equipment and also a capability to reduce consumption of chemical reactants for prevention of hydrates formation or will allow avoid their usage; will ensure reduction of noise during operation due to the mutual braking of counter meeting streams of the gas coming out of the holes. ^ EFFECT: the invention ensures improved gas cleaning, uninterrupted operation of the separator, decreased or zero consumption of chemical reactants, prevention of the secondary run of the trapped liquid phase. ^ 8 cl, 1 dwg |
