Description
Technical field
The invention belongs to a kind of environment-friendly type dangerous waste recovery process of chemical industry, mainly for caprolactam cyclohexanol production
Dangerous waste Oil recovery reaches resource maximum utilizationization, resource is avoided to reuse, waste of resource influences environment, makes to system
At waste.
Background technique
A large amount of fuel oil can be generated during cyclohexanol production, fuel oil is sold outside as dangerous waste.Fuel oil main source
Fall to drench waste oil, the waste water entrained oil that discharge and evaporating, emitting, dripping or leaking of liquid or gas generate, this part waste oil main component: hexamethylene in system equipment
52%, cyclohexene 24%, benzene 21%, light component 0.9%, cyclohexanol 1.5%, heavy constituent 0.6%, cyclohexane, cyclohexene,
The ingredient of benzene, cyclohexanol etc. 99% or so is that the effective component of system can be recycled to system.It therefore is the yield for reducing fuel oil,
Cyclohexanol device has Oil recovery system, reduces the outlet of fuel oil to the greatest extent.
Patent CN105293606A discloses oily waste liquor recovery system and recovery method during a kind of cyclohexanol production,
Including vapour source, First Heat Exchanger, the second heat exchanger, stripper and oil water separator；First Heat Exchanger and the second heat exchanger
It include thermal medium chamber and cold medium chamber；The cold medium chamber ingress of First Heat Exchanger is connected by waste pipe and waste water source
Logical, the cold medium outlet of First Heat Exchanger is connected to the top inlet of stripper, the thermal medium chamber inlet of First Heat Exchanger and
The top export of stripper is connected to, and the thermal medium chamber outlet of First Heat Exchanger and the thermal medium chamber ingress of the second heat exchanger connect
It is logical；The thermal medium chamber outlet of second heat exchanger is connected to oil water separator, and the cold medium chamber of the second heat exchanger and condensation are situated between
The connection of matter source；The lower part gas phase entrance of stripper is connected to vapour source.B-grade condensation, oil are carried out to oil mixing with water gas in the present invention
Water gaseous mixture is effectively condensed, and ensure that the big steady load operation of stripper.
Waste oil recycling system has been transformed by design and test in Xu Xiubing etc. " recycling and utilization of cyclohexanol device waste oil "
System separates the heavy component, lighter component and the water that recycle in waste oil again, improves the use value of waste oil, reduces environment dirt
Dye.
However traditional fuel oil recovery method are as follows: the waste oil wastewater collection of system discharge is into waste water tank, in waste water tank
Waste oil after static layering is pumped to solvent recovery tower by waste oil and passes through distillation operation, wherein the hexamethylene in waste oil, hexamethylene
Alkene, benzene reenter system to dehydrating tower return tank by overhead extraction and are recycled, the weight of solvent recovery tower tower reactor extraction
Group dispensing to sump tank is then sent to fuel oil service tank as dangerous waste and takes out.The defect of such technique recycling: 1, time of fuel oil
It is intermittent for receiving, due to recycling fuel oil solvent recovery tower as the purifying column in system there are mainly two types of function, it is each right
It must carry out boiling before and after Oil recovery to equipment utilization steam, the waste water of generation drain into waste water tank, waste of resource, and 2, can only
To the light component recycling in fuel oil, the alcohol ketone in tower reactor heavy constituent cannot be recycled, be taken out after being discharged as fuel oil.
