Abstract
The utility model discloses a from integrated equipment including high -efficient recovery aqueous ammonia among ammonia wastewater, the device include equipment such as evaporimeter, condenser, aqueous ammonia storage regulator, liquid packing and delivery pump. The evaporimeter adopts the conduction oil to carry out heating evaporation to containing ammonia wastewater, the condenser adopts frozen brine to cool off the gaseous ammonia that gets into the condenser and the water of vaporizing on a small quantity becomes liquid, the aqueous ammonia is stored the regulator and is used for storing and adjusts the ammonia concentration in the container, the liquid packing adopts the acidic aqueous solution to follow the gaseous ammonia of overflowing in the aqueous ammonia storage regulator in order to absorb. The utility model discloses integrated equipment can follow including the high -efficient aqueous ammonia of retrieving among the ammonia wastewater, and this aqueous ammonia is applicable to use the occasion of weak aqua ammonia in needs, and the ammonia wastewater that contains of production gets back to this device again and carries out aqueous ammonia recovery processing.
Description
[technical field]
This utility model relates to environmental protection technical field, particularly to a kind of complexes from reclaiming ammonia from ammonia-containing waste water water.
[background technology]
Aluminum trichloride (anhydrous) commonly used by catalyst used in petroleum resin production process.Aluminum chloride decomposes generation hydrochloric acid after meeting water, hardware is very easily corroded by hydrochloric acid.In order to reduce hcl corrosion, most producer adopts the ammonia of low concentration to neutralize hydrochloric acid, thus chemical industry equipment is effectively protected.Weak ammonia after neutralization can be recycled, but cycle-index too much after just become the waste water that ammonia nitrogen concentration gradually rises, if discharge beyond standards will result in the severe contamination of rivers and lakes；If being sent to waste water processing station, because the ammonia nitrogen concentration in deposed ammonia and salt are cumulative so that the intractability of waste water processing station increases.Best bet is exactly that the ammonia in ammonia-containing water is recycled; the occasion needing to use weak ammonia it is back to again after generating weak ammonia; so can reclaim ammonia; accomplish to turn waste into wealth; discharge of wastewater can be reduced again; alleviate the intractability of waste water processing station, but situation about using for the produced ammonia-containing water ammonia recovery technology of catalyst aluminum chloride protection and ammonia circulation in current domestic petroleum chemical enterprise rarely has report.
[utility model content]
(utility model purpose) the purpose of this utility model is in that: for the defect of ammonia recovery technology in existing ammonia-containing water and deficiency, and this utility model provides a kind of simple in construction, deposed ammonia recycle device reasonable in design, easy to use.
(technical scheme) for achieving the above object, the technical solution adopted in the utility model is: develop a kind of can from ammonia-containing water the complexes of efficient recovery ammonia, this device be provided with waste water vaporizer, ammonia condenser, ammonia store actuator, delivery pump etc..
Described vaporizer is built with a hotline heater, after heating, ammonia and water seethe with excitement and form ammonia after the condensation of condensed device and flow into ammonia and store actuator, can pass through heater and control the boiling temperature of ammonia-containing water and and then control the ammonia content in the ammonia condensed fluid that generates.
The effect of described ammonia condenser is that ammonia and the water vapor condensation of gaseous state are become liquid, height according to ambient temperature, condenser adopts different cooling mediums, general summer adopts chilled brine as cooling medium, further, the temperature of chilled brine should lower than 7 DEG C, and can adopt common industrial circulating water winter is cooling medium, further, the temperature of industrial circulating water is preferably 15-20 DEG C.
Described ammonia stores actuator for receiving the liquid ammonia of condenser；When ammonia-containing water temperature stabilization in vaporizer, the filling pipe that can store on actuator by opening and closing ammonia regulate the concentration of ammonia in container.
After (beneficial effect) adopts this utility model complexes that ammonia-containing water is processed, the ammonia major part in waste water is transferred to ammonia and stores in actuator, and the ammonia of recovery can utilize by iterative cycles；The waste water residual liquid total amount of base of evaporator is greatly decreased and in residual liquid, ammonia-nitrogen content significantly reduces.This utility model simple in construction, arranges rationally, and ammonia organic efficiency is high, and wastewater discharge reduces, and has good economic benefit and environmental benefit.
Fig. 1 is structure and the schematic flow sheet of this utility model complexes.
Description of reference numerals:
1, vaporizer；2, condenser；3, ammonia stores actuator；4, ammonia-containing water water inlet pipe；5, hotline heater；6, residual liquid flows to pipeline；7, filling pipe；8, water sealed tank；9, ammonium hydroxide delivery pump.
Specific implementation method
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Shown in Fig. 1, ammonia-containing water enters in vaporizer 1 by water inlet pipe 4, opens the hotline heater 5 being in base of evaporator and ammonia-containing water is heated；Heated liquid in vaporizer 1 extremely boiling, the ammonia in waste water is overflowed and with a small amount of steam from the top of vaporizer 1 in a gaseous form；The ammonia of gaseous state and steam flow in ammonia storage actuator 3 by becoming liquid after condenser 2 cooling；Waste water residual liquid in vaporizer 1 is sent to waste water station through residual liquid pipeline 6.When ammonia stores the ammonia concn in actuator 3 lower than, when setting concentration, making the ammonia level in the gaseous mixture of generation increase by reducing the heating power of hotline heater 5, thus improving ammonia to store the ammonia concn in actuator 3；When ammonia stores the ammonia concn in actuator 3 higher than, when setting concentration, being diluted strong aqua ammonia until reaching to set concentration by the filling pipe 7 on its top of unlatching；When the ammonia concn in ammonia storage actuator 3 is higher and has gaseous ammonia to overflow, the gaseous ammonia of effusion can be dissolved in equipped with in the water sealed tank 8 of acidic aqueous solution, and water sealed tank 8 can be prevented effectively from gaseous ammonia and escape into air and harm environment；If ammonia store the ammonia liquid level in actuator 3 higher, by ammonium hydroxide delivery pump 9, ammonia therein delivered to user place or pump into Ammonia vessel and store for future use.
