Description
Technical field
The present invention relates to crystallization kettle apparatus field, especially a kind of efficient crystallisation by cooling kettle.
Background technique
Currently, o-cyanobenzyl chloride is a kind of irritant smell, the colourless acicular crystals to jade green, be soluble in ethyl alcohol,
The organic solvents such as chloroform, acetone, toluene, sterling fusing point are 59.5 DEG C, belong to a kind of organic synthesis intermediate, are mainly used for closing
At diphenyl ethylene fluorescent bleaches, such as fluorescent whitening agent ER series.
O-cyanobenzyl chloride product can also generate large quantity of exhaust gas during crystallization kettle crystallizes, and the constituent of exhaust gas is main
Including the complete chlorine of unreacted, o methyl benzonitrile material and HCl gas etc., these exhaust gas are usually to pass through chlorination kettle top
The delivery pipe in portion is directly discharged to outside, and exhaust gas is cooled during passing through delivery pipe and is easy the fouling in tube wall, the row of causing
The blocking of pipe is put, and delivery pipe makes in crystallization kettle once blocking, the exhaust gas that the interior reaction of crystallization kettle generates cannot timely be discharged
Pressure becomes larger, and influences production quality, also brings some potential safety problems to the normal crystallization production of crystallization kettle.
Summary of the invention
It is deposited during crystallization kettle is crystallized and produced present invention aim to solve current o-cyanobenzyl chloride product
The above problem, a kind of efficient crystallisation by cooling kettle is provided thus.
Concrete scheme of the invention is: a kind of efficient crystallisation by cooling kettle, has autoclave body, and autoclave body outer wall is set with for containing
The collet of brine ice is respectively equipped with cryosel water inlet and cryosel water out on collet；It is equipped with feed inlet at the top of autoclave body and gives up
Gas outlet, autoclave body bottom are equipped with discharge port；It is characterized in that: fixing seat is equipped at the top of autoclave body, equipped with stirring electricity in fixing seat
The output end connection of machine and matched reduction gearbox, reduction gearbox stretches to the intracorporal shaft of kettle, and is equipped in the bottom end of shaft
Agitator arm；Control valve is respectively arranged on pipeline where the inlet port and outlet port；On pipeline where the waste gas outlet
Equipped with condenser.
The configuration of the present invention is simple, ingenious in design, crystalline rate is high, effectively eliminates exhaust gas in its delivery pipe inner pipe wall
There is a phenomenon where foulings, also ensure the safety of crystallization production.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure: 1-autoclave body, 2-collets, 3-cryosel water inlets, 4-cryosel water outs, 5-feed inlets, 6-exhaust gas go out
Mouthful, 7-discharge ports, 8-fixing seats, 9-stirring motors, 10-reduction gearboxes, 11-shafts, 12-agitator arms, 13-controls
Valve, 14-condensers.
Specific embodiment
Referring to Fig. 1, a kind of efficient crystallisation by cooling kettle has autoclave body 1, and 1 outer wall of autoclave body is set with for containing -10 DEG C of cryosels
The collet 2 of water, is respectively equipped with cryosel water inlet 3 and cryosel water out 4 on collet 2；5 He of feed inlet is equipped at the top of autoclave body 1
Waste gas outlet 6,1 bottom of autoclave body are equipped with discharge port 7；It is equipped with fixing seat 8 at the top of autoclave body 1, stirring motor is housed in fixing seat 8
9 and matched reduction gearbox 10, the output end connection of reduction gearbox 10 stretches to the shaft 11 in autoclave body 1, and in shaft 11
Bottom end is equipped with agitator arm 12；Control valve 13 is respectively arranged on pipeline where the feed inlet 5 and discharge port 7；The exhaust gas goes out
Condenser 14 is housed on the pipeline where mouth 6.
