But chuck cools down to reaction kettle, and cooling jacket is equipped with refrigerant, but since cooling jacket can only drop reaction kettle part
Temperature can not achieve the complete cooling inside raw material, cause by-product more, it is therefore desirable to make every effort to keep dispensing in blending process
The temperature of kettle stablizes the project for becoming and needing to study at present.
Invention content
In view of this, the present invention is directed to propose a kind of proportioner taking heat drop low temperature using raw material, existing to overcome
The deficiency of technology effectively avoids the variation of local temperature in batching kettle to the influence of material reaction, and simultaneously can be with feed proportioning optimization
Technique reduces production cost；Device of the present invention discharges big calorimetric suitable for blending process, and is needed in blending process
Maintain the temperature at a certain range of technique.
In order to achieve the above objectives, the technical proposal of the invention is realized in this way：
A kind of proportioner taking the low autoclave body temperature of heat drop using raw material, including batching kettle and cooling ＆ cool-storing apparatus；Institute
The heat production coil pipe for being equipped in batching kettle and being connected to by pipeline with cooling ＆ cool-storing apparatus is stated, outside is equipped with to be passed through with cooling ＆ cool-storing apparatus
The cooling jacket of pipeline connection；
Cold-storage raw material is housed in the cooling ＆ cool-storing apparatus；The heat production coil pipe is equipped in several through tubes and outside pipe
Hole.
Existing refrigerating plant may be used in cooling ＆ cool-storing apparatus, realizes the cooling of its built-in cold-storage raw material, cold-storage
Function only needs to can be realized the shell of device using attemperator.
Further, the discharge port of the cooling ＆ cool-storing apparatus is connected with charging supervisor, and charging supervisor passes through the first branch pipe
With the inlet communication of heat production coil pipe；Inlet communication of the supervisor by the second branch pipe and cooling jacket is fed simultaneously；
The refluxing opening of the cooling ＆ cool-storing apparatus is connected with return main；Return main passes through third branch pipe and heat production coil pipe
Refluxing opening connection；And return main is connected to by the 4th branch pipe with the refluxing opening of cooling jacket.
In order to reduce the cost of equipment, one return main of setting is then in place to be shunted, by cold-storage raw material point
It is fitted in heat production coil pipe and cooling jacket.
Further, charging supervisor is equipped with circulating pump, the upper and lower stream of circulating pump be respectively equipped with the first valve and
Second valve；First branch pipe is equipped with third valve；Third branch pipe is equipped with the 5th valve；4th branch pipe is equipped with the 4th valve
Door.The disengaging cold-storage raw material of heat production coil pipe and cooling jacket can be controlled respectively, according to demand, it is determined whether open or close
Valve closing door；Here each valve can be the adjustable existing valve of flow, to realize the interior of heat production coil pipe and cooling jacket
The flow velocity of cold-storage raw material it is adjustable, to realize the adjustable of dispensing temperature in the kettle.
Further, the position of the upper discharge port close to cooling ＆ cool-storing apparatus of charging supervisor is equipped with discharge valve；Reflux master
On pipe return valve is equipped with close to the position of the refluxing opening of cooling ＆ cool-storing apparatus.
Further, agitating paddle is equipped in the batching kettle, and the top of batching kettle is equipped with the electricity for driving agitating paddle rotation
Machine.
Further, cold-storage raw material is one kind in water, ethylene glycol, acid solution, metal salt solution, aqueous slkali, benzene, chlorobenzene
Or it is several.
Further, the import of the heat production coil pipe and refluxing opening are respectively positioned on the top of batching kettle, and heat production coil pipe
Bottom end is located between the bottom end and the bottom end of agitating paddle of batching kettle, and heat production coil pipe is arranged in batching kettle arrives suitable position,
It is uniform to be more conducive to injection of the cold-storage material in batching kettle, realizes uniform cooling；
The import of the cooling jacket is located at its lower end, and the refluxing opening of cooling jacket is at its upper end, and cooling jacket is under
It holds into cold-storage raw material, then flows back from upper end, convenient for the cold-storage raw material thermal energy as much as possible for absorbing batching kettle, extend and absorb heat
The time of energy.
Further, the heat production coil pipe the side towards agitating paddle be equipped with several through tubes in the circular hole outside pipe,
And the distribution density of circular hole is gradually reduced from top to bottom on heat production coil pipe.Since the thermal energy that lower section generates is unfavorable for distributing, top
Heat dissipation is very fast, therefore the circular hole density below heat production coil pipe is increased, and cold-storage raw material as much as possible is made to enter dispensing from below
In kettle.
Further, further include temperature measuring equipment, the detecting head of temperature measuring equipment is located in batching kettle.Temperature measuring equipment can be with oneself
Control system connects, and then also connect each valve with robot control system(RCS) simultaneously, realizes the automation control of entire proportioner.
Further, material total volume is the 30~70% of batching kettle volume in the batching kettle.
It is a kind of using proportioner as described above carry out dispensing technique, include the following steps, by ZSM-5 molecular sieve with
Sodium hydroxide solution is added in batching kettle, the uniform stirring 2-8h at 40-80 DEG C, rotating speed of agitator 30-100r/min, then
Cold-storage raw material in cooling ＆ cool-storing apparatus is uniformly ejected into 10-30L/min in batching kettle 7 by heat production coil pipe, it is lasting to spray
Time about 0.5-3h is penetrated, blender is stirred with 30-100r/min, when temperature is increased to 50-75 DEG C, opens cooling jacket
Reinforcement cooling function is carried out, cooling jacket is then closed when temperature is less than 30-40 DEG C, continues that 3-8h is mixed；The cold-storage
Raw material is the sulfuric acid solution or ammonium phosphate solution of 0.1-2.0mol/L；After cold-storage raw material in heat production coil pipe stops injection, match
The mass ratio of ZSM-5 molecular sieve, NaOH and the sulfuric acid or phosphoric acid that are added in material kettle is 1：(0.05-1)：(0.1-1).
A kind of technique being carried out dispensing using proportioner as described above, is included the following steps, is 5- by mass fraction
25% tetrapropylammonium hydroxide solution is put into batching kettle, rotating speed of agitator 50-300r/min, by organic amine mixed liquor
It is added in batching kettle with the speed of 10-50mL/min, then proceedes to stirring 3-6h, then by organic silicon source and fatty alcohol, organic
Titanium source is added with the speed of 10-50mL/min in batching kettle respectively, then by the aliphatic acid in cooling ＆ cool-storing apparatus by taking heat
Coil pipe is ejected into the speed of 1-5mL/min in batching kettle, ensures that the temperature in batching kettle is maintained at 20-40 DEG C when addition, after
Continuous stirring 1-5h opens cooling jacket and carries out reinforcement cooling function when temperature is increased to 35~45 DEG C, when temperature less than 18~
Cooling jacket is then closed at 24 DEG C；After cold-storage raw material in heat production coil pipe stops injection, the tetrapropyl hydrogen of addition in batching kettle (7)
Amine-oxides, organic amine, organic silicon source, fatty alcohol, organic titanium source, aliphatic acid mass ratio be (2-20)：(0.02-2)：(10-
20)：(20-50)：1：(0.05-1).
Compared with the existing technology, the proportioner of the present invention that heat drop low temperature is taken using raw material is had following excellent
