Description
Technical field
The utility model relates to phenolic resin synthesis technical fields, and in particular to a kind of phenolic resin catalyst waste solution circulation
Processing unit.
Background technique
Phenolic resin is one of the synthetic resin developed earliest, is to pass through resin made from polycondensation reaction as phenol and aldehyde, main
Wanting raw material is phenol and formaldehyde, furthermore can also use other phenols, and such as cresols, xylenol ask benzenediol and other aldehyde such as
Furfural can also be reacted with aniline, phenol with formaldehyde condensation polymer sometimes.Since phenolic resin has good physics, chemical property, and
Its low in cost, production technology and equipment requirement are simple, are widely used in industrial or agricultural various aspects.
In the synthesis of phenolic resin, under solid catalyst effect polycondensation reaction occurs for phenol and formaldehyde, and reaction terminates
Afterwards, water, solid catalyst and phenolic resin are contained in solid catalyst waste liquid, these solid catalyst waste liquids do not recycle at present
Processing unit, but it is directly discarded, cause phenolic resin material to be not fully utilized in this way, production cost is high.
Utility model content
The utility model is in view of the deficienciess of the prior art, provide a kind of phenolic resin catalyst waste solution circular treatment
Device.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of phenolic resin catalyst waste solution cyclic processing device, including evaporator, extraction kettle, elution tank, dissolution kettle and
Chimney cooler, catalyst waste solution are sent into evaporator, and evaporator outlet at bottom is connected with extraction kettle, extraction kettle outlet at bottom with
Dissolution kettle is connected, and the outlet of evaporator top gas phase is connected with elution tank, and the liquid-phase outlet for eluting tank is connected with extraction kettle, elutes tank
Gaseous phase outlet be connected with chimney cooler, chimney cooler liquid outlet with dissolution stirred tank be connected.
The working principle of utility model device is: catalyst waste solution is sent into evaporator, and low boiling component is evaporated
Come, liquid material enters in extraction kettle by evaporator outlet at bottom, and eluent phenol, which enters, to be eluted in tank to sending evaporator
Gas carry out elution processing will wherein organic principle absorb, the phenol eluent for eluting tank enters in extraction kettle to catalysis
The organic matters such as the phenol in agent mixed liquor carry out extraction processing, and the raffinate containing catalyst in extraction kettle enters dissolution kettle
In, the gas for eluting tank at the same time is cooling through subcooler, and cooling material, which is also sent, to be stirred into dissolution stirred tank with catalyst
Dissolution, then catalyst mixed liquid circulation is sent into reactive modified phenolic resin kettle.
Utility model device realizes recycling for reactive modified phenolic resin catalyst, while will be in catalyst waste solution
Organic Ingredients extracts, and improves product yield, has the advantages that design is reasonable, easy to operate low with production cost.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the connection schematic diagram of utility model device.
1 evaporator, 2 extraction kettles, 3 elution tanks, 4 dissolution kettles, 5 chimney coolers in figure.
Specific embodiment
As shown, a kind of phenolic resin catalyst waste solution cyclic processing device, including evaporator 1, extraction kettle 2, elution
Tank 3, dissolution kettle 4 and chimney cooler 5, catalyst waste solution is sent into evaporator, and evaporator outlet at bottom is connected with extraction kettle, extraction
Kettle outlet at bottom is taken to be connected with dissolution kettle, the outlet of evaporator top gas phase is connected with elution tank, elutes the liquid-phase outlet and extraction of tank
Kettle is taken to be connected, the gaseous phase outlet for eluting tank is connected with chimney cooler, and chimney cooler liquid outlet is connected with dissolution stirred tank.
The working principle of utility model device is: catalyst waste solution is sent into evaporator, and low boiling component is evaporated
Come, liquid material enters in extraction kettle by evaporator outlet at bottom, and eluent phenol, which enters, to be eluted in tank to sending evaporator
Gas carry out elution processing will wherein organic principle absorb, the phenol eluent for eluting tank enters in extraction kettle to catalysis
The organic matters such as the phenol in agent mixed liquor carry out extraction processing, and the raffinate containing catalyst in extraction kettle enters dissolution kettle
In, the gas for eluting tank at the same time is cooling through subcooler, and cooling material, which is also sent, to be stirred into dissolution stirred tank with catalyst
Dissolution, then catalyst mixed liquid circulation is sent into reactive modified phenolic resin kettle.
