Abstract

The invention discloses a multi-layer composite T-shaped pipe separator for separating two-phase flow or multiphase flow. The multi-layer composite T-shaped pipe separator comprises an inflow hole, two outflow holes and at least two composite T-shaped pipe layers, wherein a mixture flows into the separator through the inflow hole; the separated fluid can flow out of the separator through the outflow holes; each composite T-shaped pipe layer comprises two main pipes and at least two intermediate connecting pipes which are vertically communicated between the two main pipes; and one main pipe is shared between every two adjacent composite T-shaped pipe layers. The invention also provides a separation method adopting the multi-layer composite T-shaped pipe separator. In the separation method, automatic control valves arranged at the two outflow holes are used for controlling the fluid allocation proportion of the two outflow holes by respectively taking liquid level, pressure or two-phase volume fraction as a feedback control signal, so that the two-phase flow can be completely separated from each other or almost completely separated from each other. The multi-layer composite T-shaped pipe separator is simple in structure, small in volume and low in cost, and leads two phases to be separated completely according to an ideal separation model; and meanwhile, the multi-layer composite T-shaped pipe separator has a pipe-type structure, thus being more convenient to replace and maintain.

Description

technical field [0001] The invention relates to the technical field of two-phase flow or multiphase flow separation, in particular to a multi-layer composite T-shaped tube separator and a separation method for two-phase flow or multiphase flow separation. Background technique [0002] Two-phase flows such as gas-liquid, liquid-liquid, liquid-solid, gas-solid and multi-phase flows such as gas-liquid-solid are common in chemical industry, metallurgy, energy, mining, food and home appliance industries. In order to improve the economy and safety of industrial processes and to obtain a single-phase product, these different phases often need to be separated by certain methods. [0003] Traditional separators of this type mainly include separation tanks, settling tanks, and cyclone separators. However, the separation tank or settling tank is generally bulky. If it is the oil-gas and oil-water separation in offshore oil fields, a large offshore platform must be erected, which not o...
