Description
Technical field: the invention belongs to environment protection and monitoring equipment, particularly a kind of gas benzene content overproof alarm.
Background technology: well-known, (benzene C6H6) is organic compound to benzene, is to form the simplest aromatic hydrocarbon of structure, is a kind of colourless, pleasantly sweet transparency liquid at normal temperatures, and has strong aromatic odor.Flammable, poisonous, be IARC first kind carcinogenic substance, the strong refractivity of tool, volatile.Because the volatility of benzene is big, be exposed to and be easy to diffusion in the air, humans and animals sucks or skin contacts a large amount of benzene and gets in the bodies, can cause acute and Chronic Benzene Poisoning.
Benzene produces the paralysis effect to central nervous system, causes acute poisoning.Weight person headache can occur, feels sick, vomiting, in a certain state of delirium, unconsciousness, stupor, tic etc., and severe patient can be dead because of the cental system paralysis.A small amount of benzene also can make the people produce phenomenons such as sleepiness, giddy, heart rate are accelerated, have a headache, trembled, Bewu, obnubilation.Absorption contains the too much food of benzene can cause symptoms such as vomiting, stomachache, giddy, insomnia, tic, heart rate quickening, even dead.Suck benzene vapor 5-10 minute of 20000ppm and have fatal risk.Long-term suck can infringer nervous system, acute poisoning can produce neural spasm even stupor, death.After the metabolin of benzene gets into cell, combine, chromosome is changed with DNA (DNA) in the nucleus; Such as the fracture that has, the combination that has, canceration that Here it is is (figuratively speaking; Be to morph, because chromosome is inhereditary material, it is controlling structure and vital movement of cell etc.); So long-term, will cause cancer.Therefore in the leukaemic, having has the contact of benzene and organic articles thereof historical greatly.Long-term contact benzene can cause very big injury to blood, causes slow poisoning.Cause neurasthenia syndrome.Benzene can damage marrow, red blood cell, leucocyte, platelet counts is reduced, and make chromosome aberration, thereby cause leukaemia, even alpastic anemia occurs.Have research report to point out, benzene is 12-15 latent period in vivo.After the women sucks excessive benzene, can cause irregular menstruation to reach the several months, ovary can dwindle.To development of fetus and not clear as yet to the influence of male genetic power.After pregnancy period, animal sucked benzene, can cause shortage in weight, bone retardation, the bone marrow damage of the young.
To the detection of micro-benzene in the air, prior art is used three kinds of methods usually: 1, red, orange, green, blue, yellow (ROGBY): have volatile organic solvent or low-molecular-weight polymkeric substance to absorb with methyl-silicone oil etc., analyze through chromatogram then.2, colorimetrically analysing: will contain the air cryogenic refrigeration of benzene, and get off benzene is freezing, and add iron sulfate and superoxol then and obtain tawny or black precipitate, and use nitric acid dissolve again, and pass through colorimetrically analysing then.3, titrimetry: absorb airborne benzene with nitric acid, nitrated one-tenth MDNB is used the titration of titanium chloride solution then.The gas benzene content assaying method of above-mentioned three kinds of prior aries all can not real-time quantitative shows also to be difficult to the benzene content of detected gas in real time the content that exceeds standard reported to the police.
This shows that advocating the society now that people-oriented, it is necessary studying and design a kind of gas benzene content overproof alarm.
Summary of the invention: the objective of the invention is to remedy the deficiency of prior art, study and design the benzene content in the gas of a kind of real-time demonstration place to be detected, and the gas benzene content overproof alarm that exceeds standard simultaneously and report to the police.
The technical scheme that realizes the object of the invention is: a kind of gas benzene content overproof alarm; It is characterized in that comprising place to be detected gas input hole; Be communicated in the micro air pump of input hole, be communicated in the gas infrared detection sensing device of air pump, the benzene content overproof that is connected in gas infrared detection sensing device shows the warning circuit module of holding concurrently; Be connected in the benzene content overproof display screen of circuit module; Be connected in the benzene content overproof red led of circuit module, be connected in the benzene content overproof alarm buzzer of circuit module, be electrically connected in the power supply supplying module of air pump, gas infrared detection sensing device, circuit module, display screen, alarm buzzer.
The object of the invention can also take following further technical measures to realize:
Described gas infrared detection sensing device is the infrared light that utilizes its inner infrared light supply to send; Energy changing by after the absorption of the benzene in the gas to be detected converts current change quantity to through sensor, sends into the gas infrared detection sensing device that circuit module is handled.Described energy changing is the binary channels pyroelectric detector through sensor.
Described benzene content overproof show the current change quantity amplifying circuit that comprises the energy changing after benzene absorbed in the warning circuit module of holding concurrently and convert to through sensor, with comparator circuit, benzene content digital display circuit, benzene content overproof pilot lamp and the alarm buzzer driving circuit of the benzene content permissible value of setting.
The gas benzene content overproof alarm that the present invention's enforcement obtains through on probation, has compared with prior art shown following beneficial effect:
1, can show benzene content in the gas of place to be detected in real time.Three kinds of gas benzene content measurements of prior art can't not accomplish to show in real time the benzene content in the gas of place to be detected.And the gas benzene content overproof alarm that the present invention implements to obtain sucks place to be detected gas through micro air pump from the gas input hole; Pump into gas infrared detection sensing device; Under the infrared light irradiation that the infrared light supply of portion sends within it; The energy changing that is absorbed by the benzene in the gas to be detected converts current change quantity to through the binary channels pyroelectric detector; Send into the amplifying circuit of circuit module and handle, show with digital real time on LCD display by benzene content digital display circuit again, the gas benzene content overproof alarm of implementing along with the present invention to obtain move or the place is changed; Can be used in the paint production workshop, make the air benzene content detection in the gluing workshop of footwear boots, or similarly other need the place of real-time detected gas benzene content.
2, can report to the police to the benzene content overproof in the gas of place to be detected in real time, eliminate the personal safety hidden danger that causes because of the benzene content overproof thereby in time take urgent measure.Three kinds of gas benzene content measurements of prior art can't not be accomplished the benzene content overproof in the gas of place to be detected is reported to the police.And the gas benzene content overproof alarm that the present invention's enforcement obtains; Through micro air pump place to be detected gas is sucked through the gas input hole, pump into gas infrared detection sensing device, under the infrared light irradiation that the infrared light supply of portion sends within it; The energy changing that is absorbed by the benzene in the gas to be detected converts current change quantity to through the binary channels pyroelectric detector; Send into the amplifying circuit of circuit module and handle, handle by the benzene content permissible value comparator circuit of setting again, send into benzene superscale pilot lamp and alarm buzzer driving circuit; Benzene content overproof indication red light lights; Meanwhile hummer also sends abnormal alarm sound, so that take urgent measure, eliminates the personal safety hidden danger that causes because of the benzene content overproof.
