Description

TECHNICAL FIELD

[0001] The utility model belongs to the polyacrylamide production technical field, concretely relates to a polyacrylamide concentration column. BACKGROUND

[0002] The polyacrylamide concentration column mainly includes bottom tower, top tower, exhaust fan, condenser and liquid phase collector and other components. Among them, the top tower is equipped with the top tower on the bottom tower, and the heater is equipped with the bottom end of the bottom tower, and the gear switch is equipped with the heater, and the feeding window is hingedly arranged on the side surface of the bottom tower, and the observation window is arranged on the feeding window. The end of the top tower close to the bottom tower is provided with a gas phase distributor, and the end of the top tower away from the bottom tower is provided with a liquid phase distributor. The top of the top tower is connected with the exhaust fan through the gas outlet pipe, the exhaust fan is connected with the condenser through the condensing pipe, and the condenser is connected with the liquid phase collector through the liquid phase collection pipe.

[0003] In the heating process, the temperature of the polyacrylamide solution increases, which causes the increase of its viscosity. When the viscosity increases to a certain extent, the solution may adhere to the inner wall of the concentration column, the stirrer and other parts in contact with the solution. This viscous adhesion phenomenon not only affects the normal operation of the equipment, but also may cause damage to the equipment. Adhesion to the inner wall: the solution adheres to the inner wall of the concentration column, which reduces the effective volume of the equipment and reduces the production efficiency. At the same time, the adhering material may fall off and mix into the product, affecting the quality of the product. Adhesion to the stirrer: the solution adheres to the stirrer, which increases the rotating resistance of the stirrer and even causes the stirrer to jam. This not only affects the stirring effect of the equipment, but also may cause damage to the equipment. Due to the viscous adhesion of the polyacrylamide solution, the stirrer may be subjected to a large resistance during rotation. When the resistance increases to a certain extent, the stirrer may stop rotating, i.e. jamming occurs. The jamming of the stirring structure may cause the following problems: decreased stirring effect: the stirrer cannot work normally, which reduces the mixing effect of the solution and affects the quality and production efficiency of the product; equipment damage: the stirrer is subjected to excessive resistance for a long time, which may cause damage to the equipment, such as motor burnout, stirrer shaft breakage, etc. In the heating process, the concentration column needs to consume a large amount of energy to provide heat. However, due to factors such as heat preservation performance of the equipment, heat transfer efficiency and heat loss during operation, part of the heat may be lost and cannot be effectively utilized.
