Description

Technical Field

[0001] The utility model relates to the technical field of distillation equipment, in particular to condensation equipment for distillation and recovery of naphthalene. Background Art

[0002] The distillation process is very common in laboratories. The distillation equipment needs to be designed according to the physical and chemical properties of the purified products and mixtures. Among them, the condensation equipment is an indispensable equipment in distillation recovery.

[0003] In the prior art, a common condensation device is one in which condensation water flows through the outer wall of a condensation tube. The flow of condensation water takes away a large amount of heat, causing the naphthalene gas in the condensation device to crystallize, and the condensed solid small particles adhere to the inner wall of the condensation tube or the inner wall and bottom of the receiving dish.

[0004] However, it is not easy to collect a large amount of crystals on the inner wall of the condenser, which will result in a waste of materials. Utility Model Content

[0005] The utility model aims to provide a condensing device for naphthalene distillation and recovery to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a condensing device for naphthalene distillation recovery, comprising: a bottom plate, two support plates are fixedly installed on the upper surface of the bottom plate, a recovery pipe is arranged on the upper surfaces of the two support plates, a connecting pipe is fixedly connected above the recovery pipe, a first air inlet pipe is fixedly connected to the upper surface of the connecting pipe, a first air outlet pipe is fixedly connected to the upper surface of the recovery pipe, a first cover plate is clamped at one end of the recovery pipe, a second cover plate is clamped at the other end of the recovery pipe, a condensing pipe is arranged between the first cover plate and the second cover plate, a second air inlet pipe is fixedly connected to one end of the condensing pipe, and a second air outlet pipe is fixedly connected to the other end of the condensing pipe.

[0007] Preferably, one end of the condenser is sleeved with a fixing ring, and a plurality of balls are embedded around the fixing ring.

[0008] Preferably, a plurality of heat sinks are arranged between the two support plates.

[0009] Preferably, an anti-backflow pipe is provided in the connecting pipe.

[0010] Preferably, two clamping blocks are provided on one side of the recovery pipe, and a scraping device is clamped on the clamping blocks.

[0011] Preferably, the scraper device comprises a half-moon block, a long rod and a handle, the long rod is clamped with the two clamping blocks, the half-moon block is fixedly connected to one end of the long rod, and the handle is fixedly connected to the other end of the long rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model proposes that a detachable condenser is arranged in the recovery tube. Since most of the condensed naphthalene will adhere to the condenser, and a scraper device is arranged to scrape out the substances on the condenser and in the recovery tube, most of the naphthalene can be collected by simply removing the condenser and scraping off the naphthalene on the surface thereof by the scraper device, and then the naphthalene on the inner wall of the recovery tube is scraped off by the scraper device and collected. In this way, the naphthalene after distillation can be effectively collected, and the difficulty of collecting the naphthalene after distillation is effectively reduced.

[0022] One end of the recovery pipe 4 is clamped with a first cover plate 5, which can be removed along with the condenser 16. The other end of the recovery pipe 4 is clamped with a second cover plate 12, which can also be removed. A condenser 16 is arranged between the first cover plate 5 and the second cover plate 12. The condenser 16 plays a major cooling role, so that the naphthalene gas around it is crystallized into solid and attached to the condenser 16. The interior of the condenser 16 is passed with nitrogen at a relatively low temperature. One end of the condenser 16 is fixedly connected with a second air inlet pipe 7, and the second air inlet pipe 7 is passed with nitrogen at a relatively low temperature. The condenser 16 The other end is fixedly connected with a second outlet pipe 13, and the second outlet pipe 13 is connected to the exhaust gas treatment device. One end of the condenser 16 is sleeved with a fixing ring 17, and the fixing ring 17 is used to set up the condenser 16 in the recovery pipe 4. A plurality of balls 18 are embedded around the fixing ring 17. The balls 18 are used to facilitate the movement of the set condenser 16 in the recovery pipe 4. A plurality of heat sinks 3 are arranged between the two support plates 2. The heat sinks 3 are all made of metal to improve the heat dissipation efficiency.

The temperature of the naphthalene gas is high. When the naphthalene gas is cooled, it will quickly condense into fixed particles attached to the condenser tube 16. When it is necessary to remove the condenser tube 16 to take out the naphthalene, first pass enough nitrogen through the first air inlet, then untie the second cover plate 12 and the first cover plate 5, and take out the condenser tube 16 together with the first cover plate 5.

[0026] In actual use, nitrogen can be first passed through the second air inlet pipe 7, and after a period of time, naphthalene gas is passed through the first air inlet pipe 10. The temperature of naphthalene gas is high. When the naphthalene gas is cooled, it will quickly condense into fixed particles attached to the condenser tube 16. When it is necessary to remove the condenser tube 16 to take out naphthalene, first pass enough nitrogen through the first air inlet, then untie the second cover plate 12 and the first cover plate 5, and take out the condenser tube 16 together with the first cover plate 5. During the removal process, the ball 18 will roll on the side wall of the recovery tube 4, and the naphthalene on the condenser tube 16 will be recovered together through the scraping device 8. During the scraping process, the naphthalene material on the taken out condenser tube 16 is first hung and received by a vessel with a larger area, and then the naphthalene on the inner wall of the recovery tube 4 is hung, pushed from one end to the other end and received.
