Agent is vaporized and is removed, so as to the unit for improving solute concentration in solvent is operated.Vaporizer mainly includes heating chamber and vaporization chamber
Two parts are constituted, and heating chamber provides the heat required for evaporation to liquid, promotes liquid boiling to vaporize, and vaporization chamber makes gas-liquid two-phase
It is kept completely separate.Under normal circumstances, zone of heating can be set outside vaporization chamber, thermal medium is passed through in zone of heating and heat is provided for vaporization chamber
Amount.On the other hand, heat steam to be directly passed in vaporization chamber, complete evaporation and detached process.But, it is being passed through thermal medium
During, as between thermal medium and tube wall, relative motion is relatively delayed, the retention layer between thermal medium and tube wall is thicker, to heat
Transmission there is certain impact.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of rotation film boils formula vaporizer again, to carry
High heat exchange efficiency.
The present invention is achieved by the following technical solutions：
The invention provides a kind of rotation film boils formula vaporizer, including vaporization chamber, and adding located at evaporation outdoor face again
Thermosphere, the zone of heating include thermal medium entrance and thermal medium outlet, and thermal medium is passed through by the thermal medium entrance of zone of heating,
There is heat exchange and vaporization chamber between in zone of heating, be vaporization chamber heating, in the zone of heating, be additionally provided with steam pipe coil, the steaming
After the steam input of vapour coil pipe is connected with the steam raising plant of outside, its pipe shaft is entered by the coil inlet of zone of heating and is added
Thermosphere, then stretched out by coil outlets, then the disk of evaporation interior, the steam pipe coil and zone of heating is passed through by the side wall of vaporization chamber
It is between tube inlet, coil outlets, vaporization chamber and is tightly connected.
Further, the steam pipe coil is wrapped in the outer surface of vaporization chamber from the bottom to top, to ensure steam pipe coil with heat
The maximum contact area of medium, is thermal medium heating.
Further, the steam output end is tangentially passed through by the upper portion side wall of vaporization chamber, to provide tangential jet power,
Make material that film forming is forced on the medial wall of vaporization chamber, greatly enhance evaporation efficiency.
Further, the evaporation interior is additionally provided with agitating device, and the agitating device includes being extended by the top of vaporization chamber
To the shaft of bottom, the paddle being arranged on shaft, and located at the scraper plate of stirring blade tip, the scraper plate and vaporization chamber
Inwall offsets, and the shaft is rotated by electrode drive.
The present invention principle be：It is zone of heating post bake by vapourss are passed through steam pipe coil, in making zone of heating
Thermal medium is realized boiling again, and substantial amounts of gas-liquid mixture is produced in thermal medium boiling process, and thermal medium has been broken up in turbulent extent aggravation
Retention layer between tube wall, heat transfer effect are greatly improved.
The present invention has advantages below compared to existing technology：The invention provides a kind of rotation film boils formula vaporizer again, should
Vaporizer makes full use of the heat of vapourss, carries out post bake to the thermal medium of zone of heating, makes thermal medium in fluidized state,
Aggravate molecular motion, substantially reduce the retention layer thickness between thermal medium and tube wall, improve heat exchange efficiency；Meanwhile, steam
Vapour is tangentially passed through by the side wall of vaporization chamber, and film forming is forced on the medial wall that material is directly sprayed to vaporization chamber, greatly enhances steaming
Send out efficiency.
Description of the drawings
Fig. 1 is the structural representation of the steam pipe coil of the present invention；
Fig. 2 is the structural representation of the agitating device of the present invention.
Specific embodiment
Below embodiments of the invention are elaborated, the present embodiment is carried out under premised on technical solution of the present invention
Implement, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to following enforcements
Example.
Embodiment 1
Present embodiments provide a kind of rotation film and boil formula vaporizer again, with structure as illustrated in fig. 1 and 2, including evaporation
Room 1, and located at the zone of heating 2 of 1 outer surface of vaporization chamber, the zone of heating 2 is a kind of deep fat zone of heating 2, including thermal medium entrance
21 and thermal medium outlet 22, the deep fat of heating is passed through by thermal medium entrance 21, the generation and vaporization chamber 1 between in zone of heating 2
Heat exchange, is that vaporization chamber 1 is heated.In order to reduce the retention layer between zone of heating 2 and vaporization chamber 1, heat exchanger effectiveness, this reality are improved
Apply example and steam pipe coil 3 be provided with zone of heating 2, the steam input of the steam pipe coil 3 is connected with the steam generator of outside,
