Background
The rectifying tower is a tower-type gas-liquid contact device for rectifying, and utilizes the property that each component in a mixture has different volatility at the same temperature, namely the vapor pressure of each component is different at the same temperature, so that a light component (low-boiling-point substance) in a liquid phase is transferred into a gas phase, and a heavy component (high-boiling-point substance) in the gas phase is transferred into the liquid phase, thereby realizing the purpose of separation.
The liquid distributor is positioned at the upper end of the packing of the rectifying tower and uniformly distributes liquid on the surface of the packing to form initial distribution of the liquid. The initial distribution of the liquid has a great influence on the performance of the rectifying tower, so that the performance of the liquid distributor has the greatest influence on the quality of the products prepared by the rectifying tower.
The conventionally used liquid distributor is provided with a trough disc distributor and a calandria distributor, wherein the trough disc distributor collects liquid firstly, and distributes the liquid by utilizing liquid distributing holes at the bottom of a trough disc, but in the collecting process of the trough disc distributor, the liquid cannot be effectively collected because gaps exist among liquid collecting plates, and the liquid which is not collected directly enters the lower layer of a rectifying tower through the gaps without passing through the liquid distributing holes, so that the liquid is unevenly distributed; in the calandria distributor in the prior art, when the calandria close to the rectifying tower wall is too close to the inner wall, most of liquid is sprayed to the tower wall to form wall flow, especially when the spraying radius of the liquid separation holes is too large. If the liquid is far from the inner wall, the liquid near the tower wall is not uniformly distributed after being distributed.
CN202538633U provides a tube-array type liquid distributor in the prior art, wherein the liquid distribution tube is arranged at the bottom of the liquid distribution tube, the axis of the liquid distribution tube and the outer edge of the lower part of the liquid distribution tube are on the same horizontal plane, the lower part of the liquid distribution tube is uniformly provided with liquid distribution holes, and the liquid is injected through the liquid distribution holes and flows to the packing below, but when the tube-array type liquid distributor is applied to the rectifying tower, the liquid discharge tube is arranged close to the tower wall, and the injected liquid easily forms wall flow, so that the liquid distribution is not uniform.
