Abstract
The present invention relates to a kind of control application systems of air pulse, mainly include airflow convertor, flotation unit and control device；By the setting of airflow convertor parameter, steady-state gas flow is converted into pulsed gas flow, pulsed gas flow forms bubble by porous plate and enters liquid phase systems, for fine-particle minerals sorting and waste water treatment.Pulsed gas flow not only can significantly improve the efficiency of flotation unit, but also can reduce the usage amount of floatation process Chinese medicine, provide a kind of effective method to the promotion of flotation efficiency.
Description
Technical field
Present invention is mainly applied to flotation technology field, the control application system of specifically a kind of air pulse.
Background technique
The continuous growth of urban water and waste water resource at present causes China to be faced with severe water security and ecological safety
Threat, the especially pollution of heavy metal ion and organic wastewater, to society sustainable development constitute very big obstruction.
The method of flotation technology application wastewater treatment mainly there are into ion flotation and precipitate flotation at present.
Precipitate flotation and ion flotation method are usually applied in the Controlling research of waste water, be added a certain amount of collecting agent and
Foaming agent can floatingly select target mineral, but the removal rate of intended particle is not but very high.The method of removal rate is improved at present
The dosage for mainly having the pH for changing solution, increasing collecting agent and foaming agent, cannot make removal rate be greatly improved.
Therefore the present invention is using a kind of mode for changing air-flow on not consuming the extra energy, is provided, so not only
The removal rate of intended particle is improved, but also the dosage of medicament can be reduced.
Summary of the invention
The present invention provides the control application system of a set of air pulse in order to solve existing issue, and technical solution is as follows:
The control application system of a set of air pulse, which is characterized in that steady-state gas flow is converted into pulse air by airflow convertor
Stream, pulsed gas flow are passed through flotation unit, maintain certain time to obtain the concentration of survivor ion, in turn according to the size of removal rate
Reset the parameter of control device.
The airflow convertor mainly includes air compressor, pressure-regulating valve, air flow meter and solenoid valve,
Described in air compressor, pressure-regulating valve, air flow meter and solenoid valve be sequentially connected；
The flotation unit mainly includes two flotation columns, is equipped with gas chamber below flotation column, porous plate is located at gas
The upper surface of chamber is connected with the sealing of the wall surface of flotation column；
The control device is mainly exactly the console for controlling the time of electromagnetism valve frequency and switch, is patrolled by programmable
It collects controller and changes the frequency of solenoid valve and the time of switch, continuous flow is become into intermittent air-flow i.e. pulsed gas flow；
Further, the air-flow of one air inlet is converted to by two gas outlets point by the solenoid valve of two-position five-way
It is not passed through corresponding flotation column, it is by connecting element that the conduit of solenoid valve and flotation column is closely coupled；
Further, air-flow is each led into the flotation column of two porous plates, is flowed, will be steeped by the dynamic of feeding liquid
The height of foam phase controls certain height, detects the residual concentration of tailing mouth waste water ion.
Further, airflow convertor and flotation unit are tightly connected；
The present invention has the following advantages compared with prior art；(1) airflow convertor in the present invention is compressed by air
Machine, pressure-regulating valve, gas flowmeter, high-frequency electromagnetic valve control frequency and the week of high-frequency electromagnetic valve by control device
Steady-state gas flow is converted into pulsed gas flow by switch time in the phase, and structure is simple, and is not needed very big air pressure and disappeared
Consume additional energy resource；(2) by the parameter of setting airflow convertor, steady-state gas flow can be converted to pulsed gas
Stream, carrys out strengthening airflow impact force for the mode that continuous flow is converted to air pulse, can significantly improve the removal of intended particle
Rate and the dosage for reducing flotation Chinese medicine.
Detailed description of the invention
Attached drawing 1 is the schematic diagram of air pulse control application system of the invention.
Attached drawing 2 is the top view of porous plate.
In attached drawing: 1- air compressor；2- pressure-regulating valve；3- air flow meter；4- solenoid valve；5- connecting element；6-
Gas chamber；7- porous plate；8- console
Specific embodiment
Referring to attached drawing 1-2: the control application system of a set of air pulse mainly includes two parts: (1) process system,
Including airflow convertor and flotation unit, the airflow convertor includes air compressor 1, pressure-regulating valve 2, gas stream
Meter 3, solenoid valve 4 etc., the flotation unit mainly include the flotation column of two dynamic flowings；(2) control system passes through sky
Air-flow meter 3 adjusts the flow of air inlet, and control device 8 controls the time switched in the frequency and a cycle of solenoid valve 4.
Steady-state gas flow is filtered and is compressed by air compressor 1, removes moisture and impurity in air.Filtering and pressure
Gas after contracting passes through pressure-regulating valve 2, adjusts the pressure for being passed through air-flow.The gas of certain pressure is adjusted by gas flowmeter 3
Knob on solar term flowmeter body flows out gas with certain flow, and the mode of air-flow is the steady-state gas flow of constant flow at this time.
The gas of certain flow is passed through solenoid valve 4, and solenoid valve is the switch that can quickly open and close air-flow, coupled
Solenoid valve can be carried out regular regulation according to switch time in certain frequency and a cycle by control panel 8, be passed through
Electromagnetic valve element, the generation type of air-flow is from regime shift at pulsed.Gas is passed through gas through connecting element 5 by pulsed gas flow
In chamber 6, bubble can be formed through the micropore on porous plate 7 and enters liquid phase.It, can be with using pulsed gas flow by porous plate 8
The apparent removal rate for improving intended particle in waste water, mechanism are as follows:
The removal rate of intended particle in flotation unit is improved, the size of bubble has a great impact to the efficiency of flotation.Gas
Bubble needs to be long to ten times of ruler diameter or more could generate enough buoyancy realization desorptions when micropore ruler diameter, cause to generate bubble ruler diameter
It is often larger；The mode that continuous flow is converted to air pulse is carried out into strengthening airflow impact force, bubble desorption process can be reduced
In dependence to buoyancy, to make bubble be desorbed in advance with lesser scale, so that the diameter of bubble is smaller.Lesser bubble has
More deposits can be separated by the outflow of foam, and then improve the removal of intended particle by very big specific surface area
Rate.
Above-mentioned specific embodiment is used to illustrate the present invention, rather than limits the invention, of the invention
In spirit and protective scope of the claims, to any modifications and changes that the present invention makes, the model that the present invention protects is both fallen within
It encloses.
