Iron surface is cleaned, and the oxide layer of steel surface is removed.The usage amount of wherein hydrochloric acid is huge, to generate largely containing Asia
The hydrochloric acid pickling waste liquor of iron ion, if untreated with regard to direct emission, it will serious harm is generated to environment.Utilize steel acid
It is a kind of good hazardous waste recycling mode to wash hydrochloric acid pickling waste liquor production poly-iron chloride water purification agent, is generally adopted now
With oxidant technique or catalytic oxidation, i.e., mixed in reaction kettle by the way that steel hydrochloric acid pickling waste liquid is carried out gas-liquid with oxygen
It closes and carries out oxidation reaction to reach purifying waste.The consumption of raw materials of catalytic oxidation is very low, production cost economy, more next
It is more to use by numerous producers.But the reaction rate of existing catalytic oxidation is not high, main cause be gas-liquid mixed effect not
Good, in order to improve gas-liquid mixed effect, current way is to add the equipment such as stirring, liquid distributor, aerator in reaction kettle, this
Kind device production is complicated, and energy consumption is high.
Therefore a kind of simple liquid waste treating apparatus that can increase catalytic oxidation efficiency is needed.
Invention content
Of the existing technology in order to solve the problems, such as, the utility model provides a kind of applied to steel hydrochloric acid pickling waste liquid
The device of poly-iron chloride is produced, simple in structure, reaction efficiency is high.
A kind of device applied to steel hydrochloric acid pickling waste liquid production poly-iron chloride, including reaction kettle, wherein reaction kettle have
There are feed inlet, discharge port and oxygen input port, the device applied to steel hydrochloric acid pickling waste liquid production poly-iron chloride is also
Including air and liquid mixer and liquid transporting apparatus, air and liquid mixer includes the gas phase import of oxygen entrance, enters for waste liquid
Fluid inlet and the outlet being discharged for mixed liquor, wherein liquid transporting apparatus is in reaction kettle discharge port and air and liquid mixer liquid
On the access of phase import connection, the feed inlet of the outlet reaction kettle of air and liquid mixer.
Furthermore, reaction kettle also has gaseous phase outlet, and the gas phase of the gaseous phase outlet of reaction kettle and air and liquid mixer
Inlet communication.
Furthermore, the air and liquid mixer is venturi air and liquid mixer.
Furthermore, the liquid transporting apparatus is reflux pump.
Furthermore, the oxygen input port of reaction kettle and gaseous phase outlet are arranged at the top of reaction kettle.
Furthermore, the feed inlet of reaction kettle is set at the top of reaction kettle, and air and liquid mixer is mounted on above feed inlet.
The utility model has the beneficial effects that：The conventional thought that gas-liquid mixed should carry out in reaction kettle is jumped out, text is utilized
Air and liquid mixer is completed liquid phase outside reaction kettle and is mixed with the efficient of gas phase in mound, the oxygen not utilized in simultaneous reactions kettle into
Enter the utilization of venturi air and liquid mixer iterative cycles.The aeration efficiency of venturi air and liquid mixer is higher than common aerator very
It is more, so reaction efficiency is high；Entire reaction unit very simple, oxygen consumption is low, without mixing in reaction kettle, aeration, liquid distributor
Etc. equipment, so the low, low equipment investment of energy consumption, easy to maintenance.
