Description

Technical Field

[0001] The utility model relates to the technical field of vinyl sulfite, in particular to a vinyl sulfite continuous synthesis distillation device. Background Art

[0002] When synthesizing vinyl sulfite, the material needs to be distilled and extracted. However, in a vacuum reduced pressure distillation device for preparing vinyl sulfite as described in application number "CN202221301866.2", when distilling, the material needs to be exchanged after the distillation is completed, which will waste a lot of time and is not convenient for continuous synthesis of vinyl sulfite. Utility Model Content

[0003] The utility model aims to provide a continuous synthesis distillation device for vinyl sulfite to solve the problems raised in the above background technology.

[0004] A continuous synthesis distillation device for vinyl sulfite comprises a storage barrel and a collecting barrel: a circular partition is arranged inside the storage barrel, and materials are stored on the inner and outer sides of the partition respectively; a support plate is arranged at the upper end of the storage barrel, a fixed pipe is arranged at the center of the support plate, and the other end of the fixed pipe is connected to the collecting barrel.

[0005] Preferably, a bottom plate is provided at the lower end of the storage barrel, and a heating net is provided inside the bottom plate.

[0006] When the device is in use, the heating net will heat the bottom of the storage barrel, thereby raising the temperature of the material. During the heating process, the heating net will heat the material at the bottom, so that the temperature of the material at the bottom approaches the boiling point.

[0007] Preferably, two liquid exchange ports are arranged on the side of the storage barrel, one liquid exchange port opening is arranged on the inner side of the storage barrel, and the other liquid exchange port opening is arranged on the inner side of the partition.

[0008] When the liquid exchange port is in use, a valve is provided inside it, through which materials can be injected into the inner and outer sides of the partition respectively. Since the materials on the inner and outer sides of the partition can be heated and distilled separately, a time difference can be created for the material exchange between the two, thereby enabling continuous distillation work.

[0009] Preferably, a first heating ring is equidistantly arranged on the inner side of the partition, and a second heating ring is equidistantly arranged between the partition and the storage barrel.

[0010] The first heating ring and the second heating ring can heat the water on both sides of the inner and outer sides of the partition, and during the heating process, the first heating ring and the second heating ring at different heights are controlled to heat the surface of the material, so that the surface of the material reaches the boiling point, and then evaporates and flows upward in a gaseous state.

[0011] Preferably, a top plate is provided at the upper end of the partition, and discharge holes are provided at equal angles on the side surfaces of the top plate.

[0012] The evaporated fluid in the partition will flow upward through the top plate, then be discharged through the discharge hole and flow upward again. Based on this, the liquid condensed on the surface of the support plate will drip downward and flow to the outside under the guidance of the top plate, thereby heating up the external fluid and balancing the external fluid that dissipates heat faster in contact with the outside world.

[0013] Preferably, a spiral cooling pipe is provided on the inner side of the fixed pipe.

[0014] The cooling pipe is connected to the external pipeline. Cooling water flows in the cooling pipe. The cooling water can cool the hot air flow, so that the gaseous fluid can be reliquefied, and the cooling water flow direction is opposite to the gas flow direction.

[0015] Preferably, conduits are provided at equal intervals inside the cooling tube, and arc-shaped grooves are provided at equal intervals inside the conduit.

[0016] The arc groove can increase the volume in the conduit, and the gas flows through the conduit. By intermittently increasing the volume in the conduit, the gas can be more fully in contact with the cooling water, thereby increasing the liquefaction effect of the fluid.

[0017] The beneficial effects of the utility model are:

[0018] 1. When the device is in use, the internal material is divided so that two parts of the material are distilled simultaneously. During the distillation process, the temperature of the two parts of the fluid is balanced by guiding the dripping fluid so that the two parts are stabilized at the same distillation speed, so that the materials can be changed separately at different times, which is convenient for continuous distillation.

[0031] When the liquid exchange port 5 is in use, a valve is provided inside it, through which materials can be injected into the inner and outer sides of the partition 4 respectively. Since the materials on the inner and outer sides of the partition 4 can be heated and distilled respectively, a time difference can be formed between the material exchanges between the two, so that continuous distillation can be carried out.
