Description

Technical Field

[0001] The utility model belongs to the technical field of chemical product production, in particular to a butadiene finished product condenser. Background Art

[0002] Butadiene is an organic compound with the chemical formula C4H6. It is a colorless gas with a slight aromatic smell. It is insoluble in water but soluble in most organic solvents such as acetone, benzene, acetic acid, esters, etc. It is a raw material for manufacturing synthetic rubber, synthetic resin, nylon, etc. Butadiene needs to go through a condensation process during its preparation.

[0003] Most of the existing butadiene finished product condensers directly contact the butadiene gas with the outer wall of the condenser tube filled with condensate, so as to complete the heat exchange and make the butadiene liquid adhere to the outer wall of the condenser tube and then flow down from the condenser tube for collection. Most of the condenser tubes are fixed and the air inlet holes of butadiene are also fixed. Therefore, during the condensation process, some butadiene gas may not be in contact with the condenser tube and can be discharged directly, thereby causing a waste of resources. After the cooling is completed, a small amount of liquid is still attached to the condenser tube, which is difficult to extract. Therefore, a butadiene finished product condenser is urgently needed to solve this problem. Utility Model Content

[0004] The utility model aims to provide a butadiene finished product condenser to solve the problems raised in the background technology.

The other end of the connecting pipe is connected to one of the hollow disks, a sleeve is sealingly and rotatably sleeved on the tube wall of the connecting pipe, a water inlet hole is opened on the tube wall of the connecting pipe, and the water inlet hole is located at the sleeve sleeve connection, a liquid inlet pipe is fixedly connected to the side wall of the sleeve, and a water outlet pipe is fixedly connected to the other hollow disk, and a conversion pipe is rotatably connected to the water outlet pipe and extends to the outside of the sealing disk.

[0012] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0013] The butadiene finished product condenser firstly passes the butadiene gas into the interior of the condensation cylinder through two air inlet pipes, and at the same time, passes the condensate into the sleeve through the liquid inlet pipe, and then passes it into the interior of the connecting pipe and one of the hollow disks through the water inlet hole opened on the connecting pipe, and then passes the condensate into the interior of multiple condensation tubes and another hollow disk through a hollow disk, and finally discharges it through the water outlet pipe, so that the butadiene gas contacts multiple condensation tubes, and at the same time, starts its motor, and drives the connecting pipe and the two hollow disks and the condensation tubes between the two hollow disks to rotate, so as to disrupt the flow direction of the butadiene gas passed into the condensation cylinder, thereby increasing the time of the gas inside the condensation cylinder, thereby improving the contact efficiency between the gas and the condensation tube, and at the same time, thanks to the rotation of the multiple condensation tubes, the liquid on the condensation tubes can be thrown off, thereby improving the collection efficiency of the butadiene liquid. Compared with the prior art, the device can effectively improve the condensation effect of butadiene gas and the collection efficiency of butadiene liquid. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of thermal conductive plates 16 are fixedly connected to the side walls of the plurality of condensing tubes 9. The plurality of thermal conductive plates 16 are all arranged in an arc shape. The thermal conductive plates 16 can effectively increase the contact area between the condensing tubes 9 and the butadiene gas, thereby improving the condensation efficiency of the gas. A motor 10 is fixedly connected to the outer wall of the other sealing plate 2. The rotating shaft of the motor 10 rotates and extends to the interior of the condensing cylinder 1 and is fixedly connected to a connecting pipe 11. The other end of the connecting pipe 11 is connected to one of the hollow disks 7. A sleeve 12 is sealingly and rotatably sleeved on the tube wall of the connecting pipe 11. A sealing ring 17 is fixedly sleeved on the inner wall of the sleeve 12. The outer wall of the sealing ring 17 sealingly and slidably fits the outer wall of the connecting pipe 11.

The two arc blocks 15 can effectively limit the rotation of the two hollow disks 7 and multiple condenser tubes 9.

[0026] How it works

[0027] When the butadiene finished product condenser is used, the butadiene gas is first introduced into the interior of the condensation cylinder 1 through two air inlet pipes 4 fixedly connected to the side wall of one of the sealing disks 2, and the condensate is introduced into the sleeve 12 fixedly connected thereto through the liquid inlet pipe 13, and then the condensate is introduced into the interior of the connecting pipe 11 and one of the hollow disks 7 fixedly connected thereto through the water inlet hole opened on the connecting pipe 11, and then the condensate is introduced into the interior of multiple condensation tubes 9 and another hollow disk 7 through one hollow disk 7, and finally discharged through the water outlet pipe, and there is a circulation between the liquid inlet pipe 13 and the water outlet pipe. The ring mechanism realizes the circulation of the condensate, so that the butadiene gas contacts with the multiple condensation tubes 9, and at the same time, the motor 10 is started, and the motor 10 drives the connecting pipe 11 fixedly connected to the end of the rotating shaft and the two hollow disks 7 and the multiple condensation tubes 9 between the two hollow disks 7 to rotate, so as to disrupt the flow direction of the butadiene gas entering the condensation cylinder 1, thereby increasing the residence time of the gas inside the condensation cylinder 1, thereby improving the contact efficiency between the gas and the condensation tubes 9, and at the same time, thanks to the rotation of the multiple condensation tubes 9, the liquid on the condensation tubes 9 can be thrown off, thereby improving the collection efficiency of the butadiene liquid.
