  • Patent number: 11931671
    Abstract: A three-stage tubular T-shaped degassing device with microbubble axial flow and spiral flow fields is provided, which is applied to quick degassing of a gas-liquid two-phase flow. The three-stage tubular T-shaped degassing device adopts a quick degassing technology combining a microbubble uniform mixed rotational axial flow field and a spiral runner conical spiral flow field with layered jet collision reversing depth degassing. A microbubble uniform mixer is configured to adjust gas-liquid two-phase flow containing big bubbles into microbubble uniform mixed axial flow. A microbubble cyclone is configured to adjust the microbubble uniform mixed axial flow into multiple strands of rotational axial flows containing microbubbles. A rotational axial flow degasser implements the horizontal type microbubble uniform mixed multiple strands rotational axial flow degassing operation to remove most microbubbles to form axial flow gas and axial flow liquid.

  • Patent number: 11931672
    Abstract: The three-stage axial flow degassing device adopts an efficient degassing technology including a vertical high speed swirling field, a horizontal rapid axial flow field and a vertical reversing scrubbing field formed by a combination of vertical tubes; the first-stage degasser performs the first-stage segmental vertical high speed swirling degassing operation, removes the gas phase carried by the gas-containing fluid, and forms a primary gas and a primary fluid; the microporous uniform mixer breaks bubbles of the primary fluid and forms a gas-liquid uniform mixed flow; the second-stage degasser performs the second-stage horizontal vane wheel swirling generating rapid axial flow degassing operation, removes the gas phase carried by the gas-liquid uniform mixed flow, and forms a secondary gas and a secondary fluid; the third-stage degasser performs the third-stage vertical reversing deep degassing operation, removes liquid phase carried by the secondary gas, and forms a tertiary gas and a tertiary fluid.

  • Patent number: 8079189
    Abstract: A structure system of concrete building for self-heat insulation comprises a wall (1), a link beam (2) and a floor slab (3). The wall is composed of a prefabricated concrete wall for heat insulation (11) and a cast-in-place concrete wall (12). The prefabricated concrete wall (11) is a concrete panel (5), one surface of which is covered with heat insulation layer (4), and the prefabricated concrete wall (11) and the cast-in-place concrete wall (12) are cast and folded to be an integral. At the joint of the link beam and an outer wall, the link beam and the top and bottom cast-in-place concrete walls are cast to be an integral. The outer end of the link beam is covered with heat insulation layer. At the joint of the floor slab and the link beam, they are cast to be an integral.

  • Patent number: 7913469
    Abstract: A concrete load-bearing wall with compound heat-insulating layer includes wall body (1) and connecting beam (2). Two layers of prefabricated heat-insulating concrete wall bodies (11a, 11b) are set in the wall body (1) of external wall, said prefabricated heat-insulating concrete wall body (11a, 11b) is a concrete plate (5) whose external surface is covered with a heat-insulating material layer (4), every layer of the prefabricated heat-insulating concrete wall body is composed of several trough-type or L-shaped prefabricated heat-insulating concrete wall body units (13). A concrete wall body vertical rib (12) is cast in situ between two adjacent prefabricated heat-insulating concrete wall body units (13) in same layer and connects them into integrity. The upper and lower ends of the rib (12) connect together with the beam of the floor, and the external side of the connecting beam (2) is covered with the heat-insulating material layer (4).

  • Patent number: 7882669
    Abstract: A composite concrete shear wall for heat insulation comprises a wall (1) and a link beam (2). The wall (1) is composed of a prefabricated concrete wall for heat insulation (11) and a cast-in-place concrete wall. The prefabricated concrete wall (11) is a concrete panel (5), one surface of which is covered with heat insulation layer (4), and steel members (14) are embedded in the prefabricated concrete wall (11). One end of the steel members is embedded in concrete panels, and the other is projected from the heat insulation layer. The steel members are connected and located along the prefabricated concrete wall to form a framework of steel reinforcement. The prefabricated concrete wall (11) and the cast-in-place concrete wall (12) are cast and folded to be an integral.
