The present invention discloses a thin layer drying device, wherein a secondary material distribution mechanism comprises a rectangular overflow trough, a U-shaped main trough, a flow stabilizing plate, a liquid infusion main pipe and a liquid infusion tube. The upper end of the drying column is provided with a rectangular overflow trough, the upper end of the rectangular overflow trough is provided with a U-shaped main trough, a flow stabilizing plate is provided inside the U-shaped main trough, a liquid infusion main pipe is provided on one side of the U-shaped main trough, a plurality of liquid infusion tubes are provided between the liquid infusion main pipe and the U-shaped main trough, and one end of the liquid infusion tube penetrates into the U-shaped main trough. The secondary material distribution mechanism of the present invention, on the one hand, slows down the descending kinetic energy of the mother liquid, and avoids the secondary material distribution mechanism being directly impacted by the large flow mother liquid; on the other hand, it avoids the rapid fluctuation of the liquid level, causing the splashing of the material liquid, and effectively improves the uniformity of the mother liquid distribution. Under the action of the gravity and surface tension of the mother liquid and the centrifugal force of the drying column, a complete, uniform and stable liquid film can be quickly formed on the outer surface of the drying column.

A bromine production blow-out tower with a flow choking effect relates to the technical field of bromine production and comprises a fixedly arranged blow-out tower body, two sides of the blow-out tower body are respectively provided with an air inlet assembly and a brine pump which are communicated with an inner cavity of the blow-out tower body, and a mixing mechanism is arranged in the blow-out tower body. The mixing mechanism comprises a rotating pipe which is coaxial with the blowing-out tower body and is rotatably arranged, the bottom of the rotating pipe is sealed, a plurality of communicating pipes communicated with an inner cavity of the rotating pipe are uniformly distributed on the circumferential wall of the rotating pipe in the circumferential direction, one end of each communicating pipe is sealed, and a plurality of spraying heads are uniformly distributed on the outer wall of each communicating pipe in the axial direction of the communicating pipe; and water injection nozzles of the plurality of spray headers are arranged upwards. The stripping tower for bromine production solves the problems that the contact time of oxidation liquid and air is short, the contact area is small and the contact effect is poor when the existing stripping tower for bromine production is used for producing bromine; the quality of a product is influenced due to the fact that more particulate matters are contained in the air, and the cleaning process is tedious when the particulate matters are cleaned.

The present invention discloses a liquid distribution device, a heat exchanger and an air conditioner, comprising: a cylinder, an inner cylinder arranged in the cylinder, a refrigerant outlet arranged on the upper part of the cylinder, and a refrigerant inlet arranged on one side of the cylinder, so that the refrigerant spirally flows along the liquid distribution space formed by the interval between the cylinder and the inner cylinder. The conical cylinder type liquid distribution device of the present invention makes full use of the centrifugal collision separation of the spiral flow at the inlet and the secondary gravity sedimentation separation according to the different densities of the gas phase and the liquid phase in the refrigerant gas-liquid mixture, and effectively intercepts a small amount of droplets entrained in the upward airflow, and the single liquid phase refrigerant is evenly distributed at the bottom. Compared with the pressurized gas-liquid two-phase common liquid distribution, this single-phase gravity liquid distributor that first performs gas-liquid separation and then evenly distributes the liquid has a small pressure drop in the distribution liquid and a more uniform distribution of the refrigerant.

The invention relates to the technical field of rectifying towers, in particular to a cracking C9 fraction rectifying tower side line extraction device which comprises tower sections, a liquid collecting tray, a breather pipe and an extraction pipe. A liquid collecting tray is connected in the tower section, vent pipes for balancing the liquid level are uniformly distributed on the liquid collecting tray, a liquid inlet positioned above the liquid collecting tray is formed in the side wall of each vent pipe, and the opening size of each liquid inlet is gradually reduced from the upper end to the lower end; the lower end of the extraction pipe is higher than the liquid collecting tray, and the upper end of the extraction pipe is lower than the lower end of the liquid inlet. The device is mounted on a cracking C9 fraction rectifying tower and used for side-draw liquid phase production, the mounting requirement is low, even if certain mounting deviation occurs, uniform liquid distribution can be ensured, and the stability of the rectifying process is maintained.
