Plating is that metal is decorated a kind of electro-chemical machining technology of protecting and obtaining some new function; for guaranteeing the quality of plated item; make metal plating have smooth smooth good appearance and with the matrix mortise; in the production process of electroplating, can produce a large amount of plating water that take off; because many chromium, copper, nickel are contained in the inside human body there is the heavy metal element of harm, so must be through further discharging of relevant treatment.Take off at present the treatment process of crossing water and mainly contain chemical precipitation method, electrolytic process, activated carbon method etc., it is large that these methods tend to be subject to facility investment, and processing cost is high, the restriction of the factors such as factory building occupation of land.
The utility model content:
The purpose of this utility model provides spent acid underpressure distillation device, condensation restored acid liquid can directly be used as product and sell, and remaining heavy metal can be enriched to quite high content after the distillation, can directly be used as industrial chemicals processes, or deep processing, realize zero release, processing cost is low, and floor space is little.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises retort 1, electrical heater 2, condensing works 3, acid solution receiving tank 4, device for absorbing tail gas 5, water storage device 6 and water pump 7; Electrical heater 2 is arranged on the bottom of retort 1, retort 1 is connected by condensing works 3 with device for absorbing tail gas 5, the upper end of retort 1 sidewall is respectively equipped with charging opening 1-1 and thermo detector 1-4, the below of charging opening 1-1 is provided with solid discharge port 1-2, the top of retort 1 is provided with measuring cell 1-3, condensing works 3 comprises water outlet 3-1, entrance of cooling water 3-2, a mouthful 3-3 is collected in acid, tail gas outlet 3-4 and vacuum pump 3-5, water outlet 3-1 is connected 3-2 and is connected with water storage device 6 by water pipe with water coolant, be provided with water pump 7 in the water storage device 6, the below that mouthful 3-3 is collected in acid is provided with acid solution receiving tank 4, tail gas outlet 3-4 is connected with device for absorbing tail gas 5, the upper end of device for absorbing tail gas 5 is provided with tail gas absorption agent import 5-1, and tail gas absorption agent groove 5-2 is arranged on the bottom of device for absorbing tail gas 5.
Described retort 1 makes after by electrical heater 2 heating to take off and crosses water and boil to volatile components and begin gasification, the temperature of noting controlling well makes it to continue to evaporate into this component and volatilizees fully, remaining difficult volatiles continues to be heated to and takes off the plating bath evaporate to dryness, this moment stopped heating.Because what adopt in the heat-processed is underpressure distillation, absorption portion adopts jet decompression mixed flow absorption system, causes distillation pressure greatly to reduce, and condensation absorbs fully, thereby the energy consumption of distillation also can be reduced relatively.
Described condensing works 3 plays the effect of cooling for reflux, when steam passes through prolong, adds water coolant with the vapour pipe convection current, fully carries out heat exchange, makes steam be cooled to fast liquid, conveniently collects.
The pipeline of described device for absorbing tail gas 5 is back-shaped pipeline.Can guarantee that tail gas can be fully absorbed.
Described device for absorbing tail gas 5 utilizes the high flow of absorption agent, makes the tail gas pipe connecting produce negative pressure, and tail gas will enter in the back-shaped pipeline like this.
Technical process of the present utility model is that distillation, cooling and absorbing and tail gas absorb.
The utility model condensation restored acid liquid can directly be used as the product sale, and remaining heavy metal can be enriched to quite high content after the distillation, can directly be used as industrial chemicals to process, or deep processing, the realization zero release, and processing cost is low, and floor space is little.
