Abstract
The present invention relates to technical field of chemical, more particularly to a kind of falling film evaporator with cleaning device.The falling film evaporator with cleaning device includes evaporator body, and upper perforated plate and lower perforated plate are provided with the evaporator body, and some heat exchanger tubes are provided between upper perforated plate and lower perforated plate, and the heat exchanger tube top mouth of pipe is zigzag, and the top mouth of pipe stretches out upper perforated plate；The evaporator body top is provided with shower, and shower is connected by delivery pipe with cleaning pump, and evaporator body bottom is connected with collecting pipe.The falling film reboiler design with cleaning device is reasonable, and feed liquid is added from charging aperture, and feed liquid is first flowed on tube sheet, and feed liquid is overflowed in heat exchanger tube through water conservancy diversion plug after accumulating certain flow, flows, is evenly distributed from top to bottom into uniformly membranaceous；Heat pipe can be exchanged by shower to be cleaned, cleaning fluid can be recycled, and cleaning efficiency is high.
Description
（One）Technical field
The present invention relates to technical field of chemical, more particularly to a kind of falling film evaporator.
（Two）Background technology
Falling film evaporation is to add feed liquid from falling film evaporator heating chamber upper tube box, through liquid distribution and film formation device, is uniformly divided
It is fitted in each heat exchanger tube, under gravity and vacuum induced and airflow function, is flowed from top to bottom into uniformly membranaceous.In evaporator
In the course of work, heat exchanger tube by long-term use after, often have precipitum and be adhered on evaporating heat-exchanging pipe, influence heat exchange efficiency,
And in existing evaporator, feed liquid can not be evenly distributed in each heat exchanger tube after charging aperture entrance, and film forming is uneven,
Blocking, and not easy cleaning are easily caused, influences evaporation effect.
（Three）The content of the invention
The present invention is in order to make up the deficiencies in the prior art, there is provided a kind of falling film evaporator.
The present invention is achieved through the following technical solutions：A kind of falling film evaporator with cleaning device, including evaporator
Body, it is characterised in that：Upper perforated plate and lower perforated plate are provided with the evaporator body, is provided between upper perforated plate and lower perforated plate some
Root heat exchanger tube, the heat exchanger tube top mouth of pipe are zigzag, and the top mouth of pipe stretches out upper perforated plate；The evaporator body side is provided with charging
Mouthful, charging aperture is arranged on above upper perforated plate；The evaporator body top is provided with shower, and shower passes through delivery pipe and cleaning
Pump is connected, and evaporator body bottom is connected with collecting pipe, and the collecting pipe other end is connected to cleaning pump.
Further, the shower is provided with multiple spray heads.
The beneficial effects of the invention are as follows：The falling film reboiler design with cleaning device is reasonable, and feed liquid is added from charging aperture,
Feed liquid is first flowed on upper perforated plate, and feed liquid is overflowed in heat exchanger tube from the jagged mouth of pipe after accumulating certain flow, into uniform films
Shape flows from top to bottom, is evenly distributed；Heat pipe can be exchanged by shower to be cleaned, cleaning fluid can be recycled, cleaning
Efficiency high.
（Four）Brief description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Accompanying drawing 1 is the structural representation of the present invention.
In figure, 1, evaporator body, 2, upper perforated plate, 3, lower perforated plate, 4, heat exchanger tube, 5, the top mouth of pipe, 6, charging aperture, 7, spray
Shower pipe, 8, delivery pipe, 9, cleaning pump, 10, collecting pipe, 11, spray head.
（Five）Embodiment
The present invention is described in further detail with reference to specific embodiment.
As shown in Figure 1, the embodiment includes evaporator body 1, and upper perforated plate 2 is provided with the evaporator body 1 with
Tube sheet 3, is provided with some heat exchanger tubes 4 between upper perforated plate 2 and lower perforated plate 3, the top mouth of pipe 5 of heat exchanger tube 4 is zigzag, the top mouth of pipe
5 stretch out upper perforated plate 2；The both sides of evaporator body 1 are provided with charging aperture 6, and charging aperture 6 is arranged on the top of upper perforated plate 2；The evaporation
The top of device body 1 is provided with shower 7, and shower 7 is connected by delivery pipe 8 with cleaning pump 9, the connection of the bottom of evaporator body 1
There is collecting pipe 10, the other end of collecting pipe 10 is connected to cleaning pump 9.
The shower 7 is provided with multiple spray heads 11.
Feed liquid is added from charging aperture 6 during use, feed liquid first flowed on upper perforated plate 2, accumulates after certain flow feed liquid from saw
The heat exchanger tube top mouth of pipe 5 of dentation is overflowed in heat exchanger tube 4, is flowed, is evenly distributed from top to bottom into uniformly membranaceous；Pass through spray
Pipe 7 can exchange heat pipe 4 and be cleaned, and collecting pipe 10 collects the cleaning fluid flowed down from top, and cleaning pump 9 will come from collecting pipe 10
Cleaning fluid be pumped into again in delivery pipe 8, and then enter in shower 7 and exchange heat pipe 4 again and cleaned, cleaning fluid is recycled
Use, cleaning efficiency is high, improves the service life of heat exchanger tube.
One kind of embodiment described above, simply more preferably embodiment of the invention, those skilled in the art
The usual variations and alternatives that member is carried out in the range of technical solution of the present invention should all include within the scope of the present invention.
