Description

Technical Field

[0001] The utility model belongs to the technical field of condensers, and in particular relates to a condenser for steam treatment of chemical synthesis raw material medicines. Background Art

[0002] At present, a large amount of steam is often generated in the process of chemical or pharmaceutical preparation, and the steam often contains low-boiling point volatile oil. Some low-boiling point volatile oils are irritating, pollute the atmosphere, and are also easy to cause harm to the human body. In the prior art, the treatment of such low-boiling point volatile oils is to add a filter (such as an activated carbon adsorption layer) in the exhaust duct to intercept and adsorb volatile substances; the second is to lengthen the exhaust duct and use the low boiling point of the volatile oil to make it condense naturally in the pipe wall.

[0003] However, the former method consumes a lot of energy and requires frequent replacement of the filter core. The latter method has poor natural condensation effect on the tube wall. If condensation is performed using a condenser tube, the condensed volatile oil forms an oil layer on the outside of the condenser tube wall. The oil layer affects further condensation effect, and efficient heat exchange between steam and the condenser tube cannot be achieved. Utility Model Content

[0021] The present invention will be further explained below in conjunction with specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

There are two groups of connecting tubes 12 symmetrically arranged, each group includes multiple connecting tubes 12, one group of connecting tubes 12 is arranged on one end of the rotating shaft tube 11 close to the upper end rotating joint 14, and the other group of connecting tubes 12 is arranged on one end of the rotating shaft tube 11 close to the lower end rotating joint 14. In each group of connecting tubes 12, multiple connecting tubes 12 are arranged in a circular array on the outer circumferential wall of the rotating shaft tube 11, and the connection between the rotating shaft tube 11 and the connecting tube 12 is hollow, so that the rotating joint 14 is connected to the connecting tube 12, and the condenser 10 is connected between the corresponding two connecting tubes 12 in the two groups of connecting tubes 12, so that the condenser tubes 10 are distributed in a circular array in the condensation bin 19, and the condenser tubes 10 are connected to the connecting tubes 12.

[0023] like Figure 2 and Figure 3As shown, a heat exchange box 17 is connected to the outside of the shell 20, and a compressor 18, a first heat exchanger 171 and a heat dissipation fan 172 are arranged in the heat exchange box 17. One end of the compressor 18 is connected to the first heat exchanger 171 through a pipeline, and the other end of the compressor 18 is connected to the rotary joint 14 at the upper end of the rotating shaft tube 11 through a pipeline. The rotary joint 14 at the lower end of the rotating shaft tube 11 is connected to the first heat exchanger 171 through an expansion valve (the expansion valve is not shown in the figure). The compressor 18, the first heat exchanger 171, the expansion valve and the condenser 10 form a heat pump assembly for refrigerant circulation. The refrigerant in the compressor 18 is compressed into a high-temperature and high-pressure gas and enters the first heat exchanger 171. The first heat exchanger 171 adopts a fin-type heat exchanger, and the heat dissipation fan 172 blows toward the first heat exchanger 171 to dissipate heat. The fan 172 uses air to lower the temperature of the refrigerant after exchanging heat with the refrigerant in the first heat exchanger 171. The refrigerant becomes a liquid and is throttled into a gas after passing through the expansion valve. The refrigerant gas passes through the rotary joint 14 and enters the rotating shaft tube 11, and then enters the condenser 10 through the connecting pipe 12. In the condenser 10, heat is exchanged with the steam to condense the volatile oil in the steam. The refrigerant gas after heat exchange returns to the compressor 18 from the upper group of connecting pipes 12 and the upper end of the rotary joint 14. The refrigerant circulates to condense the raw material vapor. In order to increase the contact area between the condenser 10 and the steam, a condensing sheet 9 is connected to the condenser 10. The condensing sheet 9 is rectangular. The condenser 10 is connected to the middle part of the condensing sheet 9. The condensing sheet 9 expands the heat exchange area and improves the condensation effect on the steam. A first steam inlet 191 and a first steam outlet 192 are provided on the shell 20. The first steam inlet 191 and the first steam outlet 192 are connected to the interior of the condensation bin 19. The first steam inlet 191 is used to connect to an external steam delivery pipeline. The steam generated during the pharmaceutical preparation of the raw materials enters the condensation bin 19 through the first steam inlet 191, and the steam is discharged from the first steam outlet 192 after heat exchange with the condensation tube 10 and the condensation sheet 9.

The driving component includes a first motor 1 and a screw rod 6. The first motor 1 is arranged on the housing 20. The screw rod 6 is vertically arranged and movably connected to the slider 4. When the first motor 1 is working, it drives the screw rod 6 to rotate. When the screw rod 6 rotates, the slider 4 is driven to slide up and down along the slide rail 5. The nozzle 2 is arranged on the slider. The nozzle 2 is connected to the water pump 7 through a hose. The water pump 7 is connected to the first water tank 15. The water tank 15 is arranged in the housing 20 for storing the cleaning liquid. The water pump 7 pumps the cleaning liquid in the first water tank 15 out to the nozzle 2. The nozzle 2 faces the direction of the condenser 10. The nozzle 2 adopts the existing high-pressure nozzle to spray high-pressure liquid on the outer wall of the condenser 10 and the condenser sheet 9 to clean the oil layer on the condenser 10 and the condenser sheet 9. When the nozzle 2 is driven by the slider 4 to move up and down, the upper and lower parts of the condenser 10 and the condenser sheet 9 can be cleaned. When the second motor 13 drives the shaft tube 11 to rotate, the shaft tube 11 drives the condenser 10 and the condenser sheet 9 to rotate through the connecting pipe 12, so that the condenser 10 and the condenser sheet 9 can be cleaned one by one. The bottom of the condenser bin 19 is connected to the waste water tank 8, and a filter screen 194 is provided between the condenser bin 19 and the waste water tank 8.
