Liquid acquisition uniform distributor

Abstract

The invention discloses a liquid acquisition uniform distributor and relates to a liquid acquisition and uniform distribution device for ethylene glycol antimony rectification equipment. The liquid acquisition uniform distributor comprises a tower body and flange plates arranged at both ends of the tower body. The lower part inside the tower body is provided with a shelf on which guide holes are uniformly arranged. The shelf is provided with a window hole. A liquid distribution cylinder is arranged in the window hole. The cylinder wall of the liquid distribution cylinder is uniformly providedwith a plurality of rows of guide holes with consistent height positions. Guide slots corresponding to each row of guide holes are vertically arranged inside the cylinder wall. A baffle plate is arranged above the top end of the liquid distribution cylinder. The liquid acquisition uniform distributor integrates a liquid acquisition function with a liquid distribution function into a whole. No matter how much liquid is acquired, the liquid can be uniformly distributed, so that the rectification effect of a rectifying tower is obviously improved and the liquid output quantity is greatly reduced. Compared with the traditional distributor with the liquid output quantity of about 600 kilograms per ton of products, the liquid output quantity of the liquid acquisition uniform distributor is reduced to about 70 kilograms per ton of the products, the ethylene glycol consumption per ton of the products is reduced by about 210 kilograms, and the raw material cost can be saved by about 2,000RMB.

Description

technical field [0001] The invention relates to a liquid collection and uniform distribution device for chemical rectification equipment, in particular for ethylene glycol antimony rectification equipment. Background technique [0002] The liquid collecting uniform distributor is one of the key components of chemical distillation equipment. Whether its design is scientific or not directly affects the distillation effect. In the reaction process of ethylene glycol antimony, antimony trioxide reacts with ethylene glycol to generate ethylene glycol antimony and water. We need to continuously discharge the water generated by the reaction from the reaction system, so that the reaction can be completely perfected. Therefore, to improve the rectification effect of the rectification tower, in the continuous gas-liquid exchange, the water with a low boiling point is discharged from the reaction system, and the evaporation of high-boiling point ethylene glycol (boiling point 198°C) is...

AI Technical Summary

Problems solved by technology

The liquid distributors used in the past are overflow distributors and calandria distributors. The liquid distribution is uneven, and the water with a low boiling point is difficult to discharge from the reaction system. A large amount of ethylene glycol with a high boiling point is evaporated to form a mixture of water and ethylene glycol. The mixed liquid enters the receiving tower of the condenser to produce 1 ton of ethylene glycol antimony product. The output of the liquid is as high as more than 600 kg, which greatly reduces the ethylene glycol involved in the reaction. New ethylene glycol needs to be added during the reaction. A large increase in the consumption of ethylene glycol
