Description
Technical field
It the utility model is related to a kind of phenol for phenolic resin condensation, addition reaction and esterification production ink raw materials
Urea formaldehyde process units.
Background technology
The method of novolak resin has one-step method and two step method at present.The technique of one-step method is：Material, phenol and aldehyde are mixed
Condensation and addition reaction occurs after conjunction at low temperature, then adds polyalcohol, is warming up to more than 200 DEG C and esterification occurs.Should
Technique is very simple, but control of each step reaction to temperature requires higher.The heat transfer structure of traditional reactor is using single
Chuck or coil arrangement, heat transfer is slow, and the time needed for heated material and cooling material is very long, and temperature control is very ineffective
Live, particularly esterification, reaction temperature is typically higher, and material is cooled by room temperature to reaction temperature by reaction temperature
The temperature that can extremely discharge, consumes the plenty of time, and these times are often time-consuming 2~3 times of reaction temperature, are had a strong impact on
Production efficiency.The technique of two step method is：To allow phenol and aldehyde to occur condensation reaction first, generation condensation intermediate, then again with thing
Material carries out addition reaction, finally adds polyalcohol, and esterification occurs, and generates phenolic resin.The technique has material quality
It is less demanding, the characteristics of good product quality, but because existing production equipment temperature control is dumb, frequently result in condensation step
Excessively, make that the molecular weight of product is excessive, and viscosity is too high, application cost is high；Because Esterification Stage heating is slow, material stop exists
The placement of the time in condensation and addition stage is oversize, causes solubility of the intermediate product in polyalcohol to reduce, eventually affects ester
Change the speed of reaction, cause esterification incomplete, had a strong impact on product quality.The two methods of novolak resin respectively have thousand
Autumn, and the product quality influence that the performance of reactor obtains on two methods is bigger.The reactor of traditional structure will obtain
Heat transfer property, often cost is higher, manufacture it is also relatively difficult.
Utility model content
The purpose of this utility model is to provide a kind of production equipment of novolak resin, reactor tool of the present utility model
There is the advantages of heat transfer is fast, temperature control is flexible, especially suitable for novolak resin.
To improve heat transfer efficiency, accelerate heating and cooling, the reaction that phenolic resin process units of the present utility model uses
Kettle is combined using jacket heat transfer structure with coil pipe heat transfer structure, and jacket heat transfer structure is divided into two independent sectors：Upper chuck and
Lower chuck；All heat transfer structures all allow thermal medium and cold medium to pass through；Such as：During heating, coil pipe and lower chuck are passed through heat
Conduction oil, heated material, steam pipeline conveying steam, both play a part of aiding in heated material, and can is enough to enter conduction oil
Row insulation.During cooling, coil pipe and lower chuck are passed through cold conduction oil, and upper chuck is passed through cooling water, cools down material, opens condenser
And choke valve, to steam cooling condense, in upper chuck, lower chuck and coil pipe compared with solidifiable substance under the influence of, to material aid in it is cold
But, also conduction oil and cooling water are incubated；Find out from such design, due to using chuck, coil pipe and steam pipeline
Collaboration heat transfer, whether heating or cool, speed all very soon.And such design, temperature control are also very clever
Living, reason is：The temperature of condensation reaction is 100~110 DEG C, traditional reactor is heated using single chuck than relatively low
Or coil pipe heating (using 300~400 DEG C of conduction oil as heat transfer medium), the control of temperature is often not accurate enough, easily super
Temperature (to prevent overtemperature, heating needs very slow speed to be just easily controlled)；And reactor of the present utility model is used, temperature control
Just seem very easy：It is to certain temperature (being less than condensation temp), then using upper first using thermal conductivity deep fat heated material
The mode that chuck is passed through steam (about 150 DEG C, steam temperature control is very convenient, simply cannot be used for the occasion of too high-temperature) continues to rise
The temperature of high material is to condensation temp.
The temperature of esterification is 220~280 DEG C, so high reaction temperature, using traditional reactor, 5 tons of thing
Material from 120 DEG C was heated to reaction temperature, it is necessary to about 5 hours, and drop temperature (about 80 DEG C) is cooled to from 280 DEG C, about needed 3 small
When, it is seen that heating and cooling are very slow.And use reactor of the present utility model；Coil pipe joint lower chuck uses same temperature
Heat-conducting oil heating material to esterification temperature, only need about 2 hours, the time is shorter under the booster action of steam pipeline；Drop
Temperature just more accelerates, it is only necessary to which about half an hour, the time is shorter under the booster action of steam pipeline：Cooling is combined using coil pipe
Lower chuck is passed through cold conduction oil, and upper chuck is passed through cooling water, opens condenser and choke valve, forced cooling.
