Description
Technical field
The utility model relates to a kind of intelligent reverse-flow type oil smoke concentration on-line monitoring instrument, belong to electrochemistry cooking fume
Technical field.
Background technology
To implement《Law of Environmental Protection of the People's Republic of China》, oil smoke online instrument be intended to by oil smoke discharge state from
Dynamic monitoring in time, accurately and comprehensively reflects Present Situation of Environmental Quality and development trend, is environmental management, pollution source apportionment, environment
Planning, environmental evaluation provide objective scientific basis, enhance the consciousness of abiding by the law of enterprise, improve the modernization of environmentally friendly on-site law-enforcing
Level progressively reaches the final purpose for improving environmental quality.Thus intelligent reverse-flow type oil smoke concentration on-line monitoring instrument be one not
The instrument that can lack.
Oil smoke monitoring at present is detected there are four types of principle：
1st, using the oil smoke monitor of optical principle
Using the oil smoke monitor of optical principle, laser oil smoke monitor, infrared oil smoke monitor, visible gloss oil can be divided into
Cigarette monitor, but pollution problem is can't resolve, because oil smoke has dependency, it is attached to above sensor, over time
Optical sensor surface can be completely covered by, often need to clean and safeguard, concentration value can not be accurately measured.
For example, number of patent application is 201510837303.3《A kind of automatic cooking fumes detection device》It discloses using infrared
The equipment that method is detected soot gas.Infrared method basic principle is to extract gas uniform speed out, then is introduced gas into organic molten
Liquid allows gas and solution to come into full contact with, and organic substance in oil smoke can so be fully dissolved into organic solution.Then, pass through
Infrared irradiation solution measures solution and front and rear optics difference is incorporated in gas, respectively so as to compare out gas concentration.But
Infrared method has the following disadvantages：1st, organic solution belongs to hypertoxic liquid, inflammable, volatile, and play can be generated using liquid absorption method
Malicious waste liquid；2nd, it needs periodically to remove live Recycling of waste liquid, be used in this commercial environment, there is certain danger, and increase
Maintenance difficulties；3rd, it is very high to gas flow path requirement, accurate gas soakage, cost is also high；4th, the single measurement time is longer, needs
It fully absorbs, the amount of gas inhalation is also larger.
2nd, using the oil smoke monitor of electrochemical principle
It is most common electrochemistry semiconductor transducer using the oil smoke monitor of electrochemical principle, monitor can use
Single or multiple electrochemistry semiconductor transducers, but sensor self character consistency is poor, and what is measured is the dense of fixed point
Angle value, it is big substrate deviation occur, eventually leads to whole measured value and relatively large deviation occurs.
For example, number of patent application is 201710163834.8《Instrument is monitored online in cooking fume》, monitor use
Open type monitoring quantity space does not account for the influences such as air-flow, temperature, humidity.For air-flow, air-flow can influence gas and sense
The time adhered on device and reacted, accelerate evaporation, measured value is made to be lower.For temperature, electrochemistry needs to heat to make gas
Body and sensor chemically reactive itself, temperature is non-constant the linearity to be caused to shift, and cause error.For humidity
Speech, vapor adhesion can make its output valve change at once on a sensor, regardless of whether there are organic gas.To sum up, oil smoke
The electrochemical means of gasmetry will solve the destructive interference of three of the above, could realize whole good linear.
Secondly, temperature is also to influence an important factor for semiconductor transducer measures oil smoke concentration value, and same sensor is not
Under synthermal, the value of measurement is also inconsistent.Due to existing each oil smoke probe be it is exposed in air, the temperature of each placement location
It spends different, the measurement of semiconductor transducer is caused to cause relatively large deviation.
3rd, using the oil smoke monitor of ultrasonic principle
Using the oil smoke monitor of ultrasonic principle, because oil smoke is depended on above sensor, wavelength is too long, and reflecting effect is poor,
Concentration value can not accurately be measured.
4th, using the oil smoke monitor of radiation theory
Using the oil smoke monitor of radiation theory, without safety assurance, easily radiation leaks, poor safety performance, not environmentally.
