Description
Technical field
The present invention relates to a kind of systems for methane chloride wastewater treatment, it is related to methane chloride Wastewater Treatment Technology
Art field.
Background technique
Methane chloride is important industrial chemicals and solvent, generates more alkaline waste water in methane chloride production,
Processing is difficult.Currently, methane chloride waste water is largely handled using " Fenton process ", i.e., add in acid condition hydrogen peroxide,
Ferrous salt etc. carries out oxidation reaction, flocculant is then added, then carry out filters pressing, filtrate outlet after detection is qualified by filter press
To sewage treatment plant, filter cake is sent as solid waste to there is qualification mechanism to be handled." Fenton process " processing step is long, the degree of automation
It is not high, it needs manually to add medicament, the organic matter in waste water can not recycle, and treatment effeciency is low.
Summary of the invention
Long in order to solve current waste water treatment system processing step, the degree of automation is not high, needs manually to add medicament, place
Low efficiency is managed, the problems such as organic matter in waste water can not recycle.The present invention provides a kind of novel methane chloride treatment system, should
Efficiently, in high degree of automation, treated waste water methane chloride content is low for processing system；And it can recycle in waste water
Organic matter.
The present invention provides a kind of methane chloride waste water treatment system, including wastewater trough, the flash column being connected with wastewater trough
Tower bottom heat exchanger, the evaporator being connected with flash column tower bottom heat exchanger, the waste water in the evaporator top after steam heats
Gas phase is connected with evaporator-condenser, base of evaporator liquid phase is connected with flash column, flashes column overhead be connected with flash column condenser,
Flash column tower bottom is connected with flash column tower bottom heat exchanger, waste water and flash column cooler phase by flash column tower bottom heat exchanger
Even, waste water after cooling enters wastewater recycle slot, finally discharges into sewage plant.
Further technical solution, the flash column tower bottom heat exchanger be tubular heat exchanger, wastewater trough waste water and
The waste water of flash column tower bottom carries out heat exchange in flash column tower bottom heat exchanger, recycles the heat of the waste water of flash column tower bottom
Amount.
Further technical solution, the flash column are provided with stainless steel structured packing, and bottom has compressed air to be passed through
Mouthful.
Further technical solution, the evaporator-condenser and flash column condenser condensate liquid are recycled to methane chlorine
Compound process units regenerates drying unit.
Further technical solution, the evaporator are falling film evaporator.
Using technical solution of the invention: in system of the invention, the waste water in wastewater trough is by flash column tower bottom warm
Exchanger absorbs the heat of flash column tower bottom waste water, and subsequently into evaporator, waste water is by being steam heated to 85-100 in evaporator
DEG C, a large amount of organic matter and a small amount of moisture evaporated in evaporator after in evaporator-condenser condensing recovery to methane chloride
Process units regenerates drying unit, and the waste water containing micro-content organism enters flash column in evaporator, micro organic in waste water
Object is taken away to produce by flash column condenser condensing recovery to methane chloride and be filled by the compressed air being passed through from flash distillation tower bottom
Regeneration drying unit is set, flashes tower bottom waste water through flash column tower bottom heat exchanger heated waste water slot waste water, then in flash column
Cooler enters wastewater recycle slot after being cooled down by recirculated cooling water, and the waste water after detection is qualified drains into sewage plant.
Beneficial effects of the present invention: the waste water that the present invention can continuously, in efficient process methane chloride production process generate,
Treatment process high degree of automation, low energy consumption；Methane chlorination analyte detection does not go out in waste water after processing；And benefit can be recycled
With the organic matter contained in waste water.
Detailed description of the invention
Fig. 1 is a kind of flow chart of the system of methane chloride wastewater treatment.
Specific embodiment
In order to make the objectives, technical solutions and advantages of the present invention clearer, below by shown in the accompanying drawings specific
Embodiment describes the present invention.However, it should be understood that these descriptions are merely illustrative, and it is not intended to limit model of the invention
It encloses.In addition, in the following description, descriptions of well-known structures and technologies are omitted, it is of the invention to avoid unnecessarily obscuring
Concept.
As shown in Figure 1, a kind of methane chloride waste water treatment system, including wastewater trough, the flash column being connected with wastewater trough
Tower bottom heat exchanger, the evaporator being connected with flash column tower bottom heat exchanger, the waste water in the evaporator top after steam heats
Gas phase is connected with evaporator-condenser, base of evaporator liquid phase is connected with flash column, flashes column overhead be connected with flash column condenser,
Flash column tower bottom is connected with flash column tower bottom heat exchanger, waste water and flash column cooler phase by flash column tower bottom heat exchanger
Even, waste water after cooling enters wastewater recycle slot, finally discharges into sump.
Embodiment 1: the waste water methylene chloride 5800mg/L before handling in wastewater trough, 360 mg/L of chloroform, carbon tetrachloride 14
mg/L.Specific processing step: waste water is delivered to the heating of flash column tower bottom heat exchanger, the waste water after heating by pump in wastewater trough
Into evaporator.The evaporator is specifically falling film evaporator by being steam heated to 85-100 DEG C, a large amount of in waste water at this time
Methane chloride and a small amount of moisture are evaporated, and methane chloride production device regeneration is recycled to after evaporator-condenser condenses
Drying unit；Waste water in evaporator containing micro-content organism enters flash column, and trace methane chloride is dodged in flash column
Steam tower bottom compressed air be passed through the compressed air that mouth is passed through take away by flash column condenser condensation after be recycled to methane chlorine
Compound process units regenerates drying unit；Waste water of the flash column without methane chloride is laggard by flash column tower bottom heat exchanger
Enter flash column cooler by circulating water, it is cooled after waste water enter wastewater recycle slot, the inspection of wastewater recycle slot does not measure first
