Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, a packed rectifying tower with a corrugated wall structure. The inner surface of the tower body is composed of a concave-convex corrugated surface structure, liquid distributors are only arranged below a gas outlet and a feed inlet at the top of the tower body, and liquid re-distributors are not required to be arranged at other positions inside the tower body. The device structurally comprises a packing bed layer, a liquid redistributor, a demister, a tower top gas outlet pipe, a condenser, a tower top reflux inlet pipe, a tower kettle liquid outlet pipeline, a reboiler gas inlet pipe, a raw material liquid inlet pipe, a packing pressing plate, a packing supporting plate and an observation hole. The gas outlet pipeline at the top of the tower is connected with a condenser, condensate in the condenser enters the top of the tower through a liquid reflux pipeline, the bottom kettle liquid outlet pipeline of the tower kettle is connected with a reboiler, and gas coming out from the reboiler enters the tower through the gas inlet pipeline of the tower kettle. Raw material liquid in the rectification process enters the tower from a raw material inlet pipe at the middle position of the tower body, and the distribution condition of descending fluid in the rectification section in the tower can be observed through the observation holes.
The wall surface where the material bed layer is arranged in the packing type rectifying tower is of a concave-convex wavy corrugated structure, the wall surface of the corrugated structure is made of an anticorrosive and wear-resistant metal material, and the wall surfaces at other positions are flat cylindrical wall surfaces.
The top of the packing tower is provided with a demister which is fixed on a bracket on the inner surface of the tower body by bolts and is made of anticorrosive and wear-resistant metal materials.
The structure of the packing bed layer is that the packing bed layer is fixed by a packing pressing plate (upper part) and a packing supporting plate (lower part).
The packing bed layer in the packing rectification tower does not need to be arranged at equal height, and the actual height is properly adjusted according to the specific process requirements.
The working principle of the plate-type packing rectifying tower is as follows: the tower top reflux liquid of the corrugated wall surface structure packing rectifying tower is uniformly divided by a tower top liquid subdivider, the divided liquid flows along the gaps of the packing bed layers, and the heat exchange and mass transfer between cold and hot fluids are realized on the surface of the packing to finish the rectifying operation. The tower body wall surface of the packed tower adopts a concave-convex corrugated wall surface structure, so that the wall surface effect of the packed tower is weakened, the liquid cannot gather obviously after flowing through the packing bed layer, the utilization rate of the packing bed layer is improved, and the separation efficiency of the rectifying tower is further improved.
The gas outlet pipe at the top of the tower is connected with a condenser, the condensate in the condenser is connected to the top of the rectifying tower through a liquid return pipe, enters the tower through a liquid redistributor at the top of the tower, and then flows to the tower kettle through the packing layers of the rectifying section and the stripping section in sequence. The liquid outlet pipe at the bottom of the tower kettle is connected to a reboiler, the kettle liquid is vaporized after being heated by the reboiler, the obtained gas enters the tower tube through the reboiler and is connected to the tower kettle, and the ascending gas sequentially passes through packing layers of the stripping section and the rectifying section and then is discharged out of the tower through a gas outlet pipe at the top of the tower through a demister.
Liquid redistributors are arranged at the top and the feed inlet of the upper tower so as to achieve the best liquid distribution effect and the better rectification separation efficiency. The distribution effect of the liquid in the packing bed layer of the rectification section can be observed through the observation hole.
The top and the bottom of the tower in the upper tower are both butted with the tower body by adopting a flange structure, so that the filler in the tower can be conveniently replaced and maintained. The filling mode of the filler adopts wet filling, and when the filling of the filler is finished, the filler bed layer in the tower needs to be subjected to airflow drying treatment. Before the filler bed layer is dried, a filler pressing plate is needed to press and fix the filler bed layer.
The working principle of the corrugated wall surface structure packing rectifying tower is as follows: the reflux liquid at the top of the tower is uniformly divided by a liquid subdivider at the top of the tower, the divided liquid flows along the gaps of the packing bed layers, the heat exchange and mass transfer between cold and hot fluids are realized on the surfaces of the packing, and the rectification operation is finished. The tower body wall surface of the packed tower adopts a concave-convex corrugated wall surface structure, so that the wall surface effect of the packed tower is weakened, and after liquid flows through the packing bed layer, the liquid cannot gather on the tower body wall surface, so that the utilization rate of the packing bed layer is improved.
After the structure is adopted, the porosity of the filler bed layer at the tower body wall surface is reduced by modifying the tower body wall surface structure of the filler type rectifying tower, so that the flow resistance of fluid at the tower body wall surface is increased, the wall surface effect in the filler type rectifying tower is inhibited, the utilization rate of the surface area inside the filler bed layer is improved, the gas-liquid contact chance in filler is strengthened, the mass transfer efficiency is improved, and the production efficiency of the filler type rectifying tower is finally greatly improved.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
