The utility model has the main character that the dust is sucked into a crate and passes through a filter paper by a sampling tube. After the filter paper sucking dust being radiated by Beta-ray, a signal is accepted by Beta-ray receiving Geiger counter, and then the signal is transported to treat by a computer data processing center and is connected with telephone line to monitor continuously on line. The integrality of sampling and testing is realized, and sampling and testing can be simultaneously fulfilled, so the measuring accuracy is high, the concentration can be read directly, the adaptation range is wide, and the telephone line is connected to monitor continuously on line.
Description
Technical field:
The utility model relates to a kind of environment monitoring equipment, particularly a kind of β ray particle soot emissions continuous monitor that utilizes beta ray monitoring graininess flue dust.
Technical background:
Because the environmental pollutions that pollution source caused such as Industrial Boiler, boiler of power plant and Industrial Stoves are quite serious, countries in the world have all been carried out further investigation and have been controlled to this, and this just need monitor the graininess dust concentration of its discharging.Monitoring method commonly used at present has opacity method, optical transmission method, laser back scattering method, charge method, β radiation absorption method (flue build-in test) etc.Wherein to measure the theory of flue dust be according to lambert-Beer law to the opacity method, is suspended in grit in the flue gas to the degree that the mensuration light of incident weakens by mensuration, asks the method for flue dust relative concentration.Its method is, measures light to the flue gas projection, and flue dust causes that promptly measuring light weakens, and by the photoelectric sensing assembly, makes it to produce the electric signal that is directly proportional with dust content, and this signal gives displayed record continuously by potential difference meter.Optical transmission method, laser back scattering method and opacity method are more approximate, and theoretical foundation is lambert-Beer law.Utilize filtration weight method (standard method) to contrast experiment and obtain correction coefficient, then it is carried out linearity correction.This method and material particle diameter, composition, color, and disperse state relevant, nonlinearity erron is bigger; The utilization of frictional static method is flue dust high-speed motion in flue, and collision and friction can make small electric charge on the smoke particle band of insulation, the quality positive correlation of charged quantity and particle.When the collision of charged ion and static probe or when flowing through near the static probe, can on probe, produce and induce a small current impulse.The ultimate principle of filtering weight method is the ash-laden gas of certain volume, and behind the filter cylinder by known weight, the grit in the flue gas according to the weight difference and the sampling volume of filter cylinder before and after the sampling, is calculated dust content by detention.Because of the gas in the flue has certain flow velocity and pressure, also have higher temperature and humidity, and some corrosive gass are often arranged, so must adopt isokinetic sampling's method.Filter weight method accuracy height, precision is good, external many countries are decided to be standard method with the method.China is also with the standard of the method as other analytical approach of evaluation.But this method is manual mensuration, and the dynamic change of there is no telling dust concentration can not realize the flue dust METHOD FOR CONTINUOUS DETERMINATION.β radiation absorption method (flue build-in test) is to adopt radioactive source and an open ionization chamber are combined, make a probe and it is placed in the flue flue dust is surveyed, because ionization chamber is open, ash-laden gas passes from ionization chamber when promptly working, ionization chamber will soon be polluted by moisture content in the flue gas and flue dust like this, makes it can't operate as normal.
Summary of the invention:
The purpose of this utility model is exactly at the various defectives that exist in the prior art, a kind of β ray particle soot emissions continuous monitor that utilizes the powerful data processing function of computing machine to produce, and can outside flue, carry out continuous on-line monitoring.
To achieve these goals, the utility model has adopted following technical scheme: β ray particle soot emissions continuous monitor, it is characterized in that it is a sampling pipe by cantilever, compressor, filter paper and chart drive assembly thereof, beta ray source, the β ray receives geiger counter (GEIGER-MULLER DETECTOR), the S pitot tube, computer data processing unit and cage are formed, sampling pipe communicates with negative pressure source, behind the filter paper process sampling pipe xsect on the chart drive assembly, between beta ray source and β ray reception geiger counter, pass through again, the β ray receives geiger counter and computer data processing unit is realized electrically connecting, S pitot tube and compressor realize that pipeline links, temperature sensor wherein with realize electrically connecting with computer data processing unit.Sampling pipe is provided with an outer tube that adapts and connects with cage, is provided with electrothermal tube in the outer tube to avoid steam coagulation.The sampling mouth protective device of being made up of cylinder, pull bar, sampling mouth over cap a cover at the outer tube first line of a couplet is to avoid sampling pipe blocked in time spent not.Wherein the S pitot tube is the national standard product; Beta ray source (14 sources of carbon, promptly
14C) receiving geiger counter with the β ray is the standardized product that aims at the customization of this instrument.The ultimate principle of the method: β ray (electron stream) the irradiation blank filter paper that the radioactive ray nucleic is radiated, measure blank filter paper to Beta-ray degree of absorption, by sampling pipe with smoke catching on filter paper, use the filter paper behind the β radiation exposure control of dust again, measure dust collecting filter paper to Beta-ray degree of absorption, Beta-ray degree of absorption is determined dust concentration according to blank filter paper and dust collecting filter paper.Beta-ray absorption and material particle diameter, composition, color, and disperse state irrelevant, proportional with the quality of material.
As can be seen from the above technical solutions, this system has unique innovation aspect smoke dust sampling and the mensuration, be not subjected to the influence of the moisture in the size, distribution, flue gas of particle color, particle diameter, to standard method the similar course of work is arranged, possess with standard method best consistance is arranged, highly sensitive, range ability is wide, long service life, stability are high.The sampling probe of brand-new design has weakened the obstruction of flue dust to sampling pipe, and systemic-function is powerful, can connect all gases sampling probe, is applicable to that multiple variety classes atmosphere pollution monitors.Adopt β radiation absorption method to measure dust concentration, realized that sampling and test are one, sampling, test are once finished, measuring accuracy height, energy direct-reading concentration and wide accommodation.
