Technical field
The utility model relates to chemical reaction equipment technical fields, and in particular to a kind of ionic liquid reaction kettle cleaning agent can
Adjust feeding device.
Background technique
In ionic liquid synthesis and purification process, needs multiple and a large amount of use cleaning agent.Typical ionic liquid closes
At being generally divided into two steps, the first step is alkylated reaction, and second step is double decomposition anion exchange reaction.In the first step and
It in two step reaction process, is required to clean intermediate and final products using cleaning agent, to wash away unreacted part
By-product and the impurities purifying generated in raw material and reaction process.Existing common cleaning agent has following several: ether,
Ethyl acetate, methylene chloride, acetone, n-hexane, normal heptane, tetrahydrofuran, n,N-Dimethylformamide etc..Not according to reaction
Together, the feeding mode of cleaning agent is divided into dropwise addition (heat release is big when cleaning), is poured into the modes such as (highly stable when cleaning), inflow.For
Facilitate charging, feed inlet is fixed position, i.e., a certain position opening from fixed position such as kettle top or bottom or kettle, clearly
Lotion enters in kettle through feed pipe and feed inlet.
Since ionic liquid reaction temperature is widely different, from -20 DEG C to 150 DEG C, cleaning agent boiling point is also different, from 30
DEG C to 200 DEG C.Fixed position charging, has the disadvantage in that
If 1, reaction temperature is higher than cleaning agent boiling point, cleaning agent can not be fed from top, can only waiting temperature drop to
Boiling point is hereinafter, use bottom binder；
If 2, reactant density is larger, cleaning agent needs to be added from top；
3, it is while meets two above condition, then reaction kettle needs to be open 2-3, virtually increases external structure
Unstability；
4, certain ionic liquid reactions need to use a variety of cleaning agents simultaneously and are added from different location, cumbersome opening
And pipeline, operation difficulty will be increased.
Disadvantages mentioned above, prevent cleaning agent causes cleaning to imitate from adjusting coal addition position according to reaction condition and material properties
Fruit difference or undercompounding.
Utility model content
The utility model is originally intended to provide a kind of adjustable feeding device of ionic liquid reaction kettle cleaning agent, improves fixed position

Cleaning agent entrance, the cleaning agent entrance are opened in the upper end of reaction kettle；
Feed pipe, one end of the feed pipe pass through cleaning agent entrance and are connected to feed inlet.
Further, the feed inlet is set to the middle part of adjustable dense sealing plate, and setting in this way can guarantee that feed inlet can
The upper end for being moved to reaction kettle can also be moved to the lower end of reaction kettle, i.e., the position of upper, middle and lower can be with respect to.
Further, the adjustable dense sealing plate is moved up and down by shut-off mechanism, and the shut-off mechanism includes roller shutter, volume
The control device of axis, the driving device of driving spool rotation and control driving device movement, the roller shutter are installed on spool, roll up
The lower end of curtain is connect with the upper end of adjustable dense sealing plate.
Further, the other end of feed pipe connects blowning installation, and the blowning installation can be by feed pipe and charging tunnel
Remaining cleaning agent is blown in reaction kettle in road.
Further, one end setting valve one that feed inlet is connected on the feed pipe, the one end for connecting blowning installation are set
Set valve two.
Further, several branch's feed pipes, each branch are set between the valve one and valve two of the feed pipe
Feed pipe is separately connected a kind of cleaning agent.
Further, valve three is respectively provided on each branch's feed pipe.
Further, one end that valve two is arranged on the feed pipe is higher than one end of setting valve one, prevents from adding in this way
When entering cleaning agent, cleaning agent flows backward to one end of feed pipe setting valve two.
The beneficial effects of the utility model are:
1, only one cleaning agent feed inlet of the device, and a variety of cleaning agents can enter from the feed inlet, subtract significantly
The design of kettle Outer Tube is lacked and autoclave body interior design, structure is simplified.
2, the device can adjust the coal addition position of cleaning agent according to reaction condition and material properties, and regulative mode is simple,
When certain or certain cleaning agents are fed from middle part, can more sufficiently timely be contacted with reaction solution, mixing is more uniform, clearly
It is more preferable to wash effect, while reducing scavenging period.
