Description

The device of poly-iron chloride is produced applied to steel hydrochloric acid pickling waste liquid
Technical field
The utility model is related to field of waste liquid treatment, more particularly to a kind of steel hydrochloric acid pickling waste liquid that is applied to produce polychlorostyrene Change the device of iron.
Background technology
Currently, steel industry acid cleaning process is essential important step, the step is using hydrochloric acid or sulfuric acid to steel 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.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model one embodiment.
Specific implementation mode
As shown in Figure 1, a kind of device applied to steel hydrochloric acid pickling waste liquid production poly-iron chloride is disclosed, it is each attached in figure Figure grade is:Reaction kettle 1, reaction kettle discharge port 2, reflux pump 3, the fluid inlet 4 of venturi air and liquid mixer, venturi gas-liquid It is mixer 5, the gas phase import 6 of venturi air and liquid mixer, the outlet 7 of venturi air and liquid mixer, reaction kettle feed inlet 8, anti- Answer the gaseous phase outlet 9 of kettle, the oxygen input port mouthful 10 of reaction kettle.
Applied to steel hydrochloric acid pickling waste liquid produce poly-iron chloride device include reaction kettle 1, wherein reaction kettle have into Material mouth 8, discharge port 2 and oxygen input port 10, the device that poly-iron chloride is produced applied to steel hydrochloric acid pickling waste liquid further include Air and liquid mixer (the present embodiment is venturi air and liquid mixer 5) and liquid transporting apparatus (the present embodiment is reflux pump 3), gas-liquid Mixer includes the oxygen gas phase import 6 entered, the fluid inlet 4 entered for waste liquid and the outlet 7 being discharged for mixed liquor, Wherein, liquid transporting apparatus is on the access that reaction kettle discharge port 2 is connect with air and liquid mixer fluid inlet 4, air and liquid mixer Outlet 7 be connected to reaction kettle feed inlet 8.
In this present embodiment, reaction kettle 1 also has gaseous phase outlet 9, and the gaseous phase outlet 9 of reaction kettle and air and liquid mixer Gas phase import 6 is connected to.
In this present embodiment, the oxygen input port of reaction kettle and gaseous phase outlet are arranged at the top of reaction kettle.
In this present embodiment, the feed inlet of reaction kettle is set at the top of reaction kettle, and air and liquid mixer is mounted on feed inlet Side.
