Description
Technical field
This utility model relates to retracting device technical field, especially relates to a kind of waste hydrochloric acid recycling dress
Put.
Background technology
At present, need to clean steel plate with hydrochloric acid in steel plate industry, because there is iron scale in plate surface,
So the iron scale of plate surface is washed off by hydrochloric acid and can be formed ferrous oxide or iron chloride is dissolved in pickle
In, along with the carrying out of acid cleaning process, the iron concentration in pickle can raise, and free hydrochloric acid is dense
Degree can reduce accordingly, in order to keep the concentration of free hydrochloric acid in acid cleaning process, is used for removing increasing in acid solution
The iron ion added, is sent to acid regeneration device by quantitative for acid pickle, and regeneration free acid returns pickling unit,
Obtain brown iron oxide simultaneously.
Existing technology is that by spent acid pump, the waste hydrochloric acid that pickling unit comes is squeezed into the spent acid in acid regeneration station
In tank, through waste acid filter, filter out the spent acid after the solid impurity in spent acid, filtration and enter concentration
Bottom device, spent acid carries out spray cycle by preconcentrator top, carries out directly with the flue gas from roaster
Connecing heat exchange, evaporated by the portion of water in spent acid, make acid pickle be concentrated, spent acid delivers to roasting
Furnace roof portion, sprays entering roaster through spray gun and nozzle.This apparatus structure is more complicated, needs
Burning coal gas or natural gas produce high-temperature flue gas, waste the energy, and operation expense is higher, spraying roasting
The spray diameter of burning method acid spray gun is little, in order to reduce blocking, keeps good atomization, the filtration to spent acid
Require strict, multiple filter need to be set, relatively costly.For these reasons, a kind of waste hydrochloric acid of design returns
It is necessary for receiving processing means.
Utility model content
The purpose of this utility model is to provide a kind of waste hydrochloric acid recycling and processing device, uses electrical heating or remaining
Spent acid is heated by the mode of heat, saves the energy, reduces operation and maintenance cost, simultaneously structure letter
Single, operation maintenance is convenient, can process the acid-bearing wastewater that surface of steel plate produces efficiently, and reduce
Cost.
For achieving the above object, this utility model provides a kind of waste hydrochloric acid recycling and processing device, including roasting
Burn body of heater, fire door, concentrator, gas absorbing device, air extractor and air inlet pipe；
Described air inlet pipe is inserted into the bottom of described roasting body of heater, and the side of described roasting body of heater is provided with gives vent to anger
Mouthful, described gas outlet is connected with described gas absorbing device by escape pipe；
Described gas absorbing device is connected with described air extractor；
The inwall of described roasting body of heater is provided with placement spent acid dish in being lined with anticorrosive inner bag, and described roaster body
Support；
Offering inlet opening on described fire door, described inlet opening is connected with described concentrator by feed tube.
Preferably, described air inlet pipe is set to L-type, if being evenly arranged with in described air inlet pipe lower crosstalk tube
Dry passage.
Preferably, described support is uniformly arranged is four rows.
Preferably, described roasting body of heater is formed from steel, and described anticorrosive inner bag is refractory brick.
Therefore, this utility model use said structure waste hydrochloric acid recycling and processing device, use electrical heating or
Spent acid is heated by the mode of person's waste heat, saves the energy, reduces operation and maintenance cost, ties simultaneously
Structure is simple, and operation maintenance is convenient, can process the acid-bearing wastewater that surface of steel plate produces efficiently, and drop
Low cost.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model a kind of waste hydrochloric acid recycling and processing device embodiment.
Detailed description of the invention
Embodiment
Fig. 1 is the structural representation of this utility model a kind of waste hydrochloric acid recycling and processing device embodiment, such as figure
Shown in, this utility model provides a kind of waste hydrochloric acid recycling and processing device, including roasting body of heater 1, fire door 2,
Concentrator 3, gas absorbing device 4, air extractor 5 and air inlet pipe 6；Air inlet pipe 6 is inserted into roaster
The bottom of body 1, the side of roasting body of heater 1 is provided with gas outlet 7, and gas outlet 7 is by escape pipe 8 and gas
Absorption plant 4 connects；Gas absorbing device 4 is connected with air extractor 5；The interior wall liner of roasting body of heater 1
The support 10 placing spent acid dish it is provided with in having anticorrosive inner bag 9, and roasting body of heater 1；Offer on fire door 2
Inlet opening 11, inlet opening 11 is connected with concentrator 3 by feed tube 12, and this utility model uses roasting
Arranging support in body of heater, support is placed spent acid dish, the quantity of spent acid dish is determined according to the amount of spent acid,
After being passed through air in roaster body, by electrical heating or use preheating to heat, allow ferrous chloride
Reacting with iron chloride, generate ferrum oxide and hydrogen chloride gas, hydrogen chloride gas is extracted into by air extractor
In gas absorbing device, hydrogen chloride gas being converted into hydrochloric acid, absorbed hydrochloric acid can be back to produce,
And the ferrum oxide in roaster body is sold after collecting pack.
Air inlet pipe 6 is set to L-type, and air inlet pipe 6 lower crosstalk tube is evenly arranged with some passages 13,
