Description
Technical field
The utility model relates to a kind of employed liquid of chemical industry, oil, metallurgy and Thermal Power Engineering-liquid cooler that is used for, and especially is suitable for the batch fractionating of high purity substance.
Background technology
At present, known liquid-liquid cooler is made of with the heat exchanger tube that is arranged on enclosure interior housing and two ends end socket thereof.Owing to can not form uniform liquid film in heat exchanger tube, so liquid-film heat transfer coefficient is little, heat exchange is renderd a service low, and weight of equipment is big.Accumulate material easily in the heat exchanger tube of cooler or on the tube sheet in addition, difficult quilt is replaced, so be not suitable for the batch fractionating of high purity substance.
Summary of the invention
The purpose of this utility model is exactly to provide to be difficult for accumulating material in a kind of equipment in order to address the above problem, and it is big to be easy between the different component substance displacement and flow velocity, resistance is little, and higher heat transfer coefficient is arranged, and heat exchange is renderd a service high, weight of equipment is light, is suitable as the cooler of high purity substance batch fractionating.
Technical solution of the present utility model: it mainly includes cylindrical shell and two ends end socket thereof, cylindrical shell is provided with the outer cooling tube of semicanal type outward, on end socket, be provided with material inlet and material outlet, outside cylindrical shell, be provided with refrigerant import and refrigerant exit on the cooling tube, cylindrical shell is provided with refluxing opening and pressure balance mouth outward, in order to make liquid can in cylindrical shell, form uniform liquid film, be beneficial to the rapid displacement and the cooling of different component substance, designed liquid film forming distributor at falling film cooler cylindrical shell internal upper part, liquid is flowed downward along cylinder inboard wall, and form even continual liquid film in inner wall surface.In order to prevent that liquid from being taken out of from pressure balance mouth, with pressure-equalizing pipe that pressure balance mouth is connected on flinger ring is housed.
Liquid film forming distributor of the present utility model comprises ellipsoidal head and the film forming cone that is provided with interior film forming annulus, outer film forming annulus, on annulus and cylindrical shell, all be welded with rest pad, make annulus and film forming cone can be installed on the cylindrical shell, gap between film forming cone and the cylinder inboard wall is 2mm, makes the liquid film that flows down from ellipsoidal head be more uniform film shape and flows downward along cylinder inboard wall.
Because the cylinder inboard wall surface forms even continual liquid film, so this falling film cooler is compared with conventional cooler, have and be difficult for accumulating material in the equipment, be easy to replace between the different component substance, and liquid-film heat transfer coefficient is big, heat exchange is renderd a service high, and weight of equipment is light, is more suitable for the characteristics such as batch fractionating of high purity substance.
