The utility model discloses a multistage vapor liquid distributor relates to vapor liquid distributor technical field, the inner bottom wall fixed connection of flow guiding liquid tank has a plurality of angle type support strip, a plurality of angle type support strip between fixed connection respectively have annular flow guiding disc and a plurality of vertical flow guiding groove, a plurality of vertical flow guiding groove's surface all fixed connection have a plurality of long type support strip, adjacent two vertical flow guiding groove all fixed connection have reinforcing connection strip, adjacent four long type support strip all fixed connection have V type flow guiding joint, the utility model discloses a plurality of V type flow guiding joint are set up and catch vapor liquid and carry out preliminary flow guiding, let liquid be guided to annular flow guiding disc and collect by a plurality of type flow guiding joint, again be guided to filter hole and carry out secondary flow guiding to make again from a plurality of even liquid outlet pipe discharge, let liquid distribution pass through a plurality of aperture flow guiding and come out to make liquid distribution more even.

Disclosed is a process for separating a mixed hydrocarbon stream comprising 1-butene, 2-butene, heavier olefins, the process comprising introducing the mixed hydrocarbon stream into a feed section of a divided wall distillation column. The divided wall distillation column has a housing defining a middle vapor-liquid contact region, an upper vapor-liquid contact region, and a lower vapor-liquid contact region. The middle vapor-liquid contact region contains at least one vertically oriented partition that divides the middle vapor-liquid contact region into at least a feed section defined by the housing and the partition and a side draw section defined by the housing and the partition. Thermal energy is provided to the divided wall distillation column via a bottom reboiler. Additional thermal energy is provided to the divided wall distillation column by withdrawing a liquid fraction from the divided wall distillation column via side draw, heating and partially evaporating the liquid fraction in a side draw evaporator, and directing the heated, partially evaporated fraction back to the divided wall distillation column. The process maximizes the proportion of thermal energy provided at relatively low temperature levels while still minimizing the total energy demand of the process. The method further allows for a reduction in the number of trays in the feed section of the middle vapor-liquid contact zone with all other variables constant.

The utility model relates to the technical field of heating devices, and discloses a steam ejector and a steam heating pipe thereof, the steam ejector comprises a shell, a plurality of steam-liquid mixing pipes and a plurality of steam ejection pipes, a steam channel and a liquid channel are arranged in the shell, one end of the steam channel is communicated with the steam ejection pipes, and the other end of the steam channel is communicated with an external steam supply pipeline. One end of the liquid channel is communicated with the vapor-liquid mixing pipe, and the other end of the liquid channel is communicated with the inner cavity of the external container. By adopting a coaxial and same-direction double-layer sleeve structure of a liquid channel and a steam channel, a jet flow structure of a steam jet pipe and a steam-liquid mixing pipe and a straight cylindrical structure of the steam-liquid mixing pipe, to-be-heated liquid enters from the rear part of the liquid channel, so that the problems that the liquid cannot be effectively stirred after steam heating and silencing treatment, the heat cannot be dispersed, and the heating effect is poor are solved. The heating efficiency is low, and stirring or large material circulation must be added to eliminate a dead zone.

The utility model discloses a high-purity NMP (N-Methyl Pyrrolidone) liquid medicine purification system, relates to the technical field of chemical equipment, and can solve the problems that in the prior art, the concentration of liquid medicine in an NMP material temporary storage barrel is not high, and the recovery requirement is not met. The high-purity NMP liquid medicine purification system comprises a purification device, a liquid medicine temporary storage device and a liquid medicine pipeline, and further comprises a liquid outlet pipeline, a waste liquid pipeline, a waste liquid storage device and a control assembly used for controlling NMP steam liquid medicine in the liquid medicine pipeline to be selectively introduced into the liquid outlet pipeline or the waste liquid pipeline according to temperature changes. The other end of the liquid medicine pipeline is communicated with the inlet of the control assembly; one ends of the liquid outlet pipeline and the waste liquid pipeline are communicated with the outlet of the control assembly, and the other ends are respectively communicated with the liquid medicine temporary storage device and the waste liquid storage device.
