Description
Technical field
The utility model relates to phenolic resin synthesis technical fields, and in particular to a kind of phenolic resin wastewater circular treatment dress
It sets.
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.
Condensation reaction occurs for phenol and aldehyde in the prior art, generates condensation intermediate, then carries out addition reaction with material again,
Polyalcohol is finally added, esterification occurs and obtains phenolic resin, esterification is needed using a large amount of circulating waters, circulation
Green alga can be generated in water use process on pipeline and water tower inner wall, green alga accumulation will excessively seriously affect circulation
Operation, be all at present by thinking to be added chemical in circulation to eliminate green alga, chemical not environmentally, to water
Matter has an impact, and a large amount of water is furthermore contained in catalyst for esterification reaction waste liquid, and waste liquid is not recycled device at present, but straight
It connects discarded, causes water resource 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 wastewater cyclic processing device.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of phenolic resin wastewater cyclic processing device, including evaporating kettle, elutriator, distillation still, cooler, silk screen foam removal
The waste liquid of device, filter and cooling tower, reaction kettle of the esterification enters in evaporating kettle, the outlet of evaporating kettle top gas phase and elutriator phase
Even, the gas phase of elutriator enters in distillation still after condensation, and the outlet of distillation still top gas phase is connected with cooler, cooler
Liquid-phase outlet is connected by wire mesh demister with return pipe, and the heat exchange jacket outlet of reaction kettle of the esterification passes through filter and return pipe
It is connected, several ultraviolet radiators is installed, return pipe is connected with cooling tower on return water inside pipe wall.
Utility model device is killed back by the way that ultraviolet radiator is arranged in cooling tower return pipe by physics irradiation
Green alga in water pipe to ensure the stable operation of circulation, while will also produce the separation of the water in waste liquid to conduct
Recirculated water supplement, improves the utilization rate of water resource, has the advantages that design reasonable, easy to operate and environmental protection and energy saving.
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 reaction kettle of the esterification, 2 evaporating kettles, 3 elutriators, 4 distillation stills, 5 coolers, 6 wire mesh demisters, 7 filters, 8 in figure
Return pipe, 9 ultraviolet radiators, 10 cooling towers.
Specific embodiment
As shown, a kind of phenolic resin wastewater cyclic processing device, including it is evaporating kettle 2, elutriator 3, distillation still 4, cold
But device 5, wire mesh demister 6, filter 7 and cooling tower 10, the waste liquid of reaction kettle of the esterification 1 enter in evaporating kettle, at the top of evaporating kettle
Gaseous phase outlet is connected with elutriator, and the gas phase of elutriator enters in distillation still after condensation, the outlet of distillation still top gas phase with
Cooler is connected, and the liquid-phase outlet of cooler is connected by wire mesh demister with return pipe 8, and the heat exchange jacket of reaction kettle of the esterification goes out
Mouth is connected by filter with return pipe, and several ultraviolet radiators 9, return pipe 8 and cooling tower 10 are installed on return water inside pipe wall
It is connected.
Utility model device is killed back by the way that ultraviolet radiator is arranged in cooling tower return pipe by physics irradiation
Green alga in water pipe to ensure the stable operation of circulation, while will also produce the separation of the water in waste liquid to conduct
Recirculated water supplement, improves the utilization rate of water resource, has the advantages that design reasonable, easy to operate and environmental protection and energy saving.
