Description
technical field:
The utility model relates to the treatment unit of furfural production waste water.
background technology:
Furfural production technology adopts sulfuric acid as catalyzer, and raw material adopts corn cob etc.Conventionally by after raw material pulverizing, add sulfuric acid, stir, send in hydrolysis kettle, pass into steam from hydrolysis kettle bottom, furfural hydrolysis being obtained with steam is taken hydrolysis kettle out of and is formed aldehyde gas, aldehyde gas forms stoste after condensation, and stoste is after distillation, by the waste water that is of discharging at the bottom of distillation tower tower.Waste water comprises large water gaging, acetic acid, high boiling material etc.The unprocessed direct discharge of waste water, pollutes the environment.
Summary of the invention
The utility model is exactly the treatment unit that a kind of furfural production waste water will be provided, and this apparatus structure is simple, is convenient to manipulation, and design science is reasonable, and treated furfural production waste water does not pollute the environment.
The technical scheme that the utility model provides is:
Furfural production waste water treatment unit, on the first heat exchanger, be provided with aldehyde gas entrance and stoste outlet, the waste liquid relief outlet of the first heat exchanger bottom is connected with the entrance of pump, pump outlet is connected with the waste liquid entrance at the second heat exchanger top, the first steam outlet of the first heat exchanger is connected with the entrance of the first flasher bottom, the outlet at the first flasher top is connected with the second heat exchanger steam entry, the waste liquid relief outlet of the second heat exchanger bottom is connected with the entrance of pump, the water outlet of the second heat exchanger is connected with water pot, the second steam outlet of the second heat exchanger bottom is connected with the entrance of the second flasher bottom, second outlet at flasher top and the entrance of condenser are connected, the outlet of condenser connects water pot.
Concrete, described the first waste liquid relief outlet place, heat exchanger bottom is provided with the first sewage draining exit.
Concrete, described the second waste liquid relief outlet place, heat exchanger bottom is provided with the second sewage draining exit.
The waste water that the utility model produces furfural production process carries out evaporation process recycling, has solved current furfural waste-water pollution problem, has realized furfural waste-water zero release, greatly reduces production cost.The utility model drops into little, and working cost is low, and convenient cleaning and maintenance, does not affect furfural and normally produce.

Embodiment
As shown in Figure 1, furfural production waste water treatment unit, on the first heat exchanger, be provided with aldehyde gas entrance and stoste outlet, the waste liquid relief outlet of the first heat exchanger bottom is connected with the entrance of pump, pump outlet is connected with the waste liquid entrance at the second heat exchanger top, the first steam outlet of the first heat exchanger is connected with the entrance of the first flasher bottom, the outlet at the first flasher top is connected with the second heat exchanger steam entry, the waste liquid relief outlet of the second heat exchanger bottom is connected with the entrance of pump, the water outlet of the second heat exchanger is connected with water pot, the second steam outlet of the second heat exchanger bottom is connected with the entrance of the second flasher bottom, second outlet at flasher top and the entrance of condenser are connected, the outlet of condenser connects water pot.
Described the first waste liquid relief outlet place, heat exchanger bottom is provided with the first sewage draining exit.
Described the second waste liquid relief outlet place, heat exchanger bottom is provided with the second sewage draining exit.
Aldehyde gas enters after the first heat exchanger through aldehyde gas entrance, and cooling forms stoste, is discharged by stoste outlet.Waste water, by the waterwater entrance at the first heat exchanger top, after the first heat exchanger, heats up.A part forms water vapour and enters the first flasher through the first steam outlet, and part becomes current and goes back to the first heat exchanger bottom, and residue water vapour enters the second heat exchanger, forms water after cooling, enters water pot.After waste water heats up, fall into the waste liquid of the first heat exchanger bottom, squeeze into the waste liquid entrance at the second heat exchanger top through pump, heat up.A part forms water vapour and enters the second flasher through the second steam outlet, and part becomes current and goes back to the second heat exchanger bottom, and residue water vapour enters condenser, finally enters water pot.After waste liquid heats up, fall into the second heat exchanger bottom, again squeeze into the waste liquid entrance at the second heat exchanger top through pump.
Described the first waste liquid relief outlet place, heat exchanger bottom is provided with the first sewage draining exit, the dirt forming for discharging the first heat exchanger bottom.
Described the second waste liquid relief outlet place, heat exchanger bottom is provided with the second sewage draining exit, the dirt forming for discharging the second heat exchanger bottom.
