Description
Technical field
The utility model relates to a kind of accurate feeders of wastewater treatment, belong to technical field of waste water processing.
Background technique
In wastewater treatment, biochemical processing method is most widely used, according to different function divisions, can be divided into anaerobism, lack
Oxygen, aerobic system.Requirement of each system to oxygen in water is different, and wherein anaerobic environment requires the dissolved oxygen control in water body
In 0.2mg/L hereinafter, oxygen depletion system control is in 0.2~0.5mg/L, aerobic system is controlled in 2~2.5mg/L.Its control range
It is relatively narrow, at the same each system air demand number, directly affect the growth and breeding of microorganism in system, and then influence whole system
Working order, it is serious to will lead to whole system collapse.
Traditional air supply system, power unit is always in full load operation, and the extra air that power section acting generates is again
It enters in atmosphere, the energy consumption of system is high, uneconomical.
Utility model content
Purpose of the utility model is to solve the control of wastewater treatment biochemical unit dissolved oxygen and energy consumption problems, especially
It is the micro- oxygen system for having very high request to dissolved oxygen, proposes a kind of accurate feeder of wastewater treatment.
The purpose of this utility model is achieved through the following technical solutions.
A kind of accurate feeder of wastewater treatment, including frequency conversion fan, dissolved oxygen monitor, valve control system, from
Control system and control cabinet matched.
Frequency conversion fan controls frequency conversion by PLC for giving device gas supply, to realize that air quantity is adjusted, when reaching requirement
When dissolved oxygen, blower reduces frequency, then air output reduces；When dissolved oxygen does not reach requirement, blower improves frequency, then air output liter
It is high；Pipeline is carbon steel piping, flanged joint；
Dissolved oxygen monitor provides real-time monitoring signal for whole device, passes through the dissolved oxygen value and reality being arranged in PLC
The deviation of actual value adjusts the frequency of frequency conversion fan；And it is used for valve control system；
Valve control system automatically opens machinery valve according to the signal of dissolved oxygen monitor, and two groups of front and back is closely matched
It closes, further control enters the gas flow of system；
Robot control system(RCS) passes through the gap between the dissolved oxygen content being arranged in PLC and actual measured value, adjust automatically blower
Frequency and valve control system.
Beneficial effect
The present invention provides a certain amount of air quantity by frequency conversion fan, passes through dissolved oxygen monitor, valve control system
Cooperation provides accurate air quantity, dissolved oxygen needed for intelligent maintenance system to aerator.The present invention is the integrated design,
It is not influenced by aerator type, can be adapted to all aerators, and automatization level is high, and precise control is stable.
Detailed description of the invention
Fig. 1 is the process flow chart of the utility model.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples.
Embodiment 1
A kind of accurate feeder of wastewater treatment, as shown in Figure 1, including includes frequency conversion fan, dissolved oxygen monitor, valve
Accelerator control system, robot control system(RCS) and control cabinet matched.The device is mainly used for the wastewater treatment lists for needing to be precisely controlled dissolved oxygen
Member sets the range for needing to control, and by dissolved oxygen monitor, the first feedback, blower is acted, after the completion of blower movement,
If being still not up to system requirements, valve automatically begins to act, and adjusts aperture, has realized and preset range.
The device is mainly used for systems to need the range of dissolved oxygen relatively narrow, such as: the anaerobic condition of 0.8~1.0mg/L is led to
Being precisely controlled for waste water treatment system dissolved oxygen can be realized by crossing the present apparatus, the microbial bacteria needed with system in Natural Selection waste water
Group, to make system stable and high effective operation.
Frequency conversion fan, the gas supply device of the utility model control frequency conversion by PLC, thus realize volume of air supply difference,
When reaching the dissolved oxygen of requirement, blower reduces frequency；When dissolved oxygen does not reach requirement, blower improves frequency；Pipeline is carbon steel
Pipeline, flanged joint；
Dissolved oxygen monitor provides real-time monitoring signal for whole device, passes through the dissolved oxygen value and reality being arranged in PLC
The deviation of actual value adjusts blower frequency and valve control system；
Valve control system opens machinery valve slowly automatically, and the tight fit of two groups of front and back, further control enters the gas of system
The scale of construction；
Robot control system(RCS) passes through the gap between the dissolved oxygen content being arranged in PLC and actual measured value, adjust automatically blower
Frequency and valve control system.
Above-described specific descriptions have carried out further in detail the purpose of utility model, technical scheme and beneficial effects
It describes in detail bright, it should be understood that the foregoing is merely specific embodiment of the utility model, is not used to limit this practical
Novel protection scope, within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done,
It should be included within the scope of protection of this utility model.
