Description
Technical field
The utility model relates to technical field of mechanical equipment, specifically a kind of desalination plant for propylene glycol production system.
Background technology
In the system of dimethyl carbonate production by transesterification joint production of propylene glycol, the application of novel carbonization technology makes the yield of propylene glycol greatly improve, and the sodium carbonate of material dissolution can not be filtered system interception and enter next system in system, the sodium carbonate dissolved in such material can be separated out after propylene glycol dehydration tower in tower, anti-dirty stifled tower tray can make sodium carbonate drop in tower reactor, can affect heat absorption and the blocking reboiler of tower reactor for a long time, and the material of tower reactor can cause after entering propylene glycol treating tower same problem to occur.
Summary of the invention
For solving the technical problem of above-mentioned existence, the utility model provides a kind of desalination plant for propylene glycol production system, sodium carbonate solution in propylene glycol dehydration tower carried out sedimentation, filter and remove, avoid sodium carbonate to accumulate in tower reactor and cause waste of steam and blocking reboiler.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of desalination plant for propylene glycol production system, include Multistage settling device and bar strainer, described Multistage settling device includes shell, traverse baffle and overflow plate, described overflow plate is set to multiple and according to being fixedly installed in turn from high to low and shell inner bottom part, described traverse baffle is set to multiple and is interspersedly fixedly installed between multiple overflow plate, the height of described traverse baffle is lower than the height of minimum overflow plate, described Multistage settling device one upper lateral part is provided with opening for feed, opposite side bottom is provided with discharge port, the position of described opening for feed is higher than the highest overflow plate, the position of described discharge port is higher than the height of traverse baffle, described Multistage settling device is connected with bar strainer by topping-up pump.
The utility model devises the Multistage settling device with multiple overflow plate and traverse baffle, and in conjunction with bar strainer, the crystals of sodium carbonate of sodium carbonate solution in propylene glycol dehydration tower is carried out Multistage settling, and carry out filtration removal by bar strainer, enter propylene glycol refining system, solve the problem of tower reactor waste steam and blocking reboiler, improve refinement level, decrease labor strength, effectively improve the quality of product, reduce the energy consumption of production process.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As shown in Figure 1, this is used for the desalination plant of propylene glycol production system, include Multistage settling device 1 and bar strainer 2, described Multistage settling device 1 includes shell 11, traverse baffle 12 and overflow plate 13, described overflow plate 13 is set to multiple and according to being fixedly installed in turn from high to low and shell 11 inner bottom part, described traverse baffle 12 is set to multiple and is interspersedly fixedly installed between multiple overflow plate 13, the height of described traverse baffle 12 is lower than the height of minimum overflow plate 13, described Multistage settling device 1 one upper lateral part is provided with opening for feed 14, opposite side bottom is provided with discharge port 15, the position of described opening for feed 14 is higher than the highest overflow plate 13, the position of described discharge port 15 is higher than the height of traverse baffle 12, described Multistage settling device 1 is connected with bar strainer 2 by topping-up pump 3.
In the present embodiment, reboiler 7, propylene glycol dehydration tower 6, tower reactor discharging pump 5, Multistage settling device 1, topping-up pump 3, bar strainer 2, propylene glycol treating tower charging stock tank 4 connect in turn, wherein tower reactor discharging pump 5 is connected with the opening for feed 14 of Multistage settling device 1, and topping-up pump 3 is connected with the discharge port 15 of Multistage settling device 1.Such mode of connection, decrease the residence time of material in propylene glycol dehydration tower 6, the design of multistage overflow plate 13, make sodium carbonate solid particles settling better effects if, the design of traverse baffle 12, reduce material back mixing, be conducive to solid particles sediment, the two combines and adds the residence time of material in sedimentation device 1, effect of settling is better, and bottom voucher, salification cleaning is more convenient, reduce the working strength of bar strainer 2 in lower step operation, guarantee that remaining crystals of sodium carbonate fully filters removal, for next step meticulous producing propylene glycol is prepared, solve the problem of tower reactor waste steam and blocking reboiler, improve the quality of product.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
