Description
Technical field
The utility model relates to wastewater treatment equipment, is specifically related to a kind of nitration waste water concentrating unit.
Background technology
Nitro-compound can produce nitration waste water in process of production, wherein contains a certain amount of nitropheneol, nitrobenzene and salt, and nitropheneol, nitrobenzene belong to difficult for biological degradation compound.Thereby our company adopts and first waste water circulation is applied mechanically, then the treatment process of evaporation concentration, organism and water are recycled, reduce the discharge of pollutent, protection of the environment.Owing to containing a certain amount of nitropheneol, nitrobenzene and salt in nitration waste water, conventionally the tube still heater vaporizer adopting, in evaporating concentration process, the easy crystallization of organism and salt results in blockage, vaporization efficiency is low, and nitropheneol is wherein flammable and explosive substance, and concentration process exists certain potential safety hazard.
Summary of the invention
The purpose of this utility model is: a kind of nitration waste water concentrating unit is provided, and this apparatus structure is simple, avoids stopping up, and vaporization efficiency is high.
Technical solution of the present utility model is: this nitration waste water concentrating unit comprises rotating scraper evaporator, concentrated solution surge tank, pneumatic diaphragm pump, concentrated solution basin, condenser and condensate tank, rotating scraper evaporator is provided with nitration waste water import, secondary steam outlet and concentrated solution outlet, the concentrated solution outlet of rotating scraper evaporator bottom is connected with concentrated solution surge tank opening for feed by pipeline, concentrated solution surge tank bottom discharge mouth is connected with pneumatic diaphragm pump inlet by pipeline, pneumatic diaphragm pump discharge is connected with concentrated solution basin opening for feed by pipeline, the secondary steam outlet on rotating scraper evaporator top is connected with the opening for feed of condenser by pipeline, condenser discharge port is connected with condensate tank by pipeline, concentrated solution surge tank with on condenser, be equipped with vacuum interface and be connected vacuum, whole formation nitration waste water concentrating unit.
The utility model adopts rotating scraper evaporator, and waste water enters rotating scraper evaporator, first through cloth tray, distributes, by blade, swept and scrape again, coating filmform in heat conductive wall, rete is subject to thermal evaporation, avoid stopping up, vaporization efficiency is shell and tube evaporator 4 times, improved the security of producing.
Accompanying drawing explanation
Fig. 1 is structural principle schema of the present utility model.
In figure: 1 rotating scraper evaporator, 2 concentrated solution surge tanks, 3 surge pumps, 4 concentrated solution basins, 5 condensers, 6 condensate tanks.
Embodiment
As shown in Figure 1, this nitration waste water concentrating unit comprises rotating scraper evaporator 1, concentrated solution surge tank 2, pneumatic diaphragm pump 3, concentrated solution basin 4, condenser 5 and condensate tank 6, rotating scraper evaporator 1 is provided with nitration waste water import, secondary steam outlet and concentrated solution outlet, the concentrated solution outlet of rotating scraper evaporator 1 bottom is connected with concentrated solution surge tank 2 opening for feeds by pipeline, concentrated solution surge tank 2 bottom discharge mouths are connected with pneumatic diaphragm pump 3 imports by pipeline, pneumatic diaphragm pump 3 outlets are connected with concentrated solution basin 4 opening for feeds by pipeline, the secondary steam outlet on rotating scraper evaporator 1 top is connected with the opening for feed of condenser 5 by pipeline, condenser 5 discharge ports are connected with condensate tank 6 by pipeline, concentrated solution surge tank 2 with on condenser 5, be equipped with vacuum interface and be connected vacuum, whole formation nitration waste water concentrating unit.
During production, nitration waste water enters rotating scraper evaporator 1 by pipeline and under vacuum state, carries out evaporation concentration, the secondary steam that evaporation obtains enters condenser 5 and carries out condensation, condensed water enters condensate tank 6 and stores recycling, the concentrated solution that evaporation obtains enters concentrated solution surge tank 2, through pneumatic diaphragm pump 3, squeeze into concentrated solution basin 4 again and store, finally go burning disposal.
