Description
Technical field
The production technical field of versatic acid is the utility model is related to, it is particularly a kind of to be used in versatic acid production process use
Condensation reflux unit.
Background technology
Versatic acid is the relatively stable industrial chemicals of a kind of chemical property, because its acid, fusing point and boiling point are teased than corresponding
Brothers carbonic acid is low, and the derivative property after reaction is also highly stable, therefore determines to ride and occupy in the industrial production
Very important effect.In process of production, tertiary carbon acid solution needs to export after rectification process versatic acid, distillation process
In, tertiary carbon acid solution needs to flow back after condenser condenses from after rectifying column output.Between traditional rectifying column and condenser
To be set up in parallel, i.e., condenser is generally arranged at the side of rectifying column, but since part versatic acid is crystalline solid at normal temperatures,
Therefore line clogging easily occurs in condensation process, rectification efficiency is low.
Utility model content
The utility model technical issues that need to address there is provided a kind of condensation reflux unit of versatic acid rectifying, energy
Enough avoid the problem that causing line clogging due to part tertiary carbon acid crystal in distillation process, further improve rectifying effect
Rate.
In order to solve the above technical problems, technical solution adopted in the utility model is as follows.
A kind of condensation reflux unit of versatic acid rectifying, including condenser, the condenser are arranged on the tower of rectifying column
Top, the lower part of condenser interlude are connected with rectifying column tower top, and the bottom that condenser is located on the outside of rectifying column is provided with cooling water
Import, the other end top of condenser are provided with cooling water outlet；The top fixed setting of the rectifying inner wall of tower is useful for receiving
The annular collection trough of tertiary carbon acid solution and crystalline solid after collection cooling, corresponds to and solution reflux is provided with the rectifying inner wall of tower of collecting tank
Export, solution reflux inlet is provided with the rectifying inner wall of tower below collecting tank, connection solution reflux is provided with outside rectifying column
Outlet and the reflux line of solution reflux inlet.
A kind of condensation reflux unit of above-mentioned versatic acid rectifying, position of the solution bypass outlet on rectifying tower side wall
Put higher than the position for collecting trench bottom on rectifying tower side wall.
A kind of condensation reflux unit of above-mentioned versatic acid rectifying, is provided with return valve on the reflux line, positioned at returning
Flow and a flushing pipe is connected by threeway on the reflux line between valve and solution bypass outlet, be provided with the flushing pipe
Purge valve.
As a result of above technical scheme, technological progress acquired by the utility model is as follows.
The utility model by varying rectifying column and condenser position, and rectifying column top set annular collect
Groove, can collect the crystalline particle for condensing and falling by condenser, and uncrystallized tertiary carbon acid solution is then flowed back by pipeline
Into rectifying column, avoid crystalline solid and the phenomenon of line clogging is occurred, further increase rectification efficiency.

Fig. 1 is the structure diagram of the utility model.
Wherein：1. rectifying column, 2. condensers, 3. collecting tanks, 4. reflux lines, 5. return valves, 6. purge valves.
Figure cathetus arrow flows to for cooling water, and curve arrow moves towards for tertiary carbon acid solution.
Embodiment
The utility model is further elaborated below in conjunction with specific embodiment.
A kind of condensation reflux unit of versatic acid rectifying, its structure include condenser 2, the condenser 2 as shown in Figure 1
The tower top of rectifying column 1 is arranged on, the lower part of condenser interlude is connected with rectifying column tower top, and condenser is located on the outside of rectifying column
Bottom is provided with cooling water inlet, and cooling water outlet is provided with the top of the other end of condenser
In the utility model, the top of rectifying inner wall of tower is fixedly installed annular collection trough 3, tertiary carbon after being cooled down for collection
Acid solution and crystalline solid, correspond to and are provided with solution bypass outlet on the rectifying inner wall of tower of collecting tank, solution bypass outlet is in rectifying
Position on tower side wall is higher than position of 3 bottom of collecting tank on rectifying tower side wall, in order to which the crystalline solid of collection is deposited on receipts
Collect groove slot bottom, avoid tertiary carbon acid solution after cooling from blocking reflux line in reflux course；In rectifying column below collecting tank
Solution reflux inlet is provided with wall, the return duct of connection solution bypass outlet and solution reflux inlet is provided with outside rectifying column
Road 4.
Return valve 5 is provided with reflux line 4, is passed through on the reflux line between return valve and solution bypass outlet
Threeway connects a flushing pipe, and purge valve 6 is provided with flushing pipe.The setting of return valve and purge valve, can control return duct
The working status in road.That is, in distillation process, return valve is opened, and purge valve cut-off, tertiary carbon acid solution after cooling can be by returning
Flow tube road is back in rectifying column；After distillation process, closing volume valve, opens purge valve, will be deposited on collecting tank slot bottom
Crystalline solid discharged by flushing pipe.
The operation principle of the utility model is：It is cold to enter condenser progress from the versatic acid gas-liquid that rectifying column rises from tower top
But, tertiary carbon acid solution after cooling is fallen after rise into collecting tank, and the crystalline solid in tertiary carbon acid solution is then deposited in collecting tank slot bottom,
Tertiary carbon acid solution is then back in rectifying column by reflux line, avoids the blocking of pipeline.After distillation process, it can pass through
Collecting tank is rinsed, the crystalline solid of collecting tank slot bottom is discharged by flushing pipe.
