Description
Technical field
The present invention relates to a kind of monitor, especially relate to a kind of structural improvement to fume concentration direct-reading monitor.
Background technology
Because the environmental pollution that the pollution source such as Industrial Boiler, boiler of power plant and Industrial Stoves cause is quite serious, countries in the world all conduct in-depth research this and are controlled, and this just need to monitor the graininess dust concentration of its discharging.Monitoring method commonly used has opacity method, optical transmission method, laser backscatter method, charge method, mouthful attenuation sensors (flue build-in test) etc. at present.Wherein, it is now the most widely used filtering weight method, and its ultimate principle is the ash-laden gas of certain volume, and behind the filter cylinder by known weight, the grit in the flue gas according to weight difference and the sampling volume of filter cylinder before and after the sampling, is calculated dust content by detention.Because 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.The weight method accuracy is high, precision is good owing to filter, and 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.
Chinese invention patent has been announced a kind of sampling of measuring dust concentration for the β attenuation sensors, measure integrated apparatus, the patent No. 200520030868, this invention relates to a kind of sampling of measuring dust concentration for the β attenuation sensors, measure integrated apparatus, this device is provided with the reconnaissance seat, be provided with the slideway in order to plug sampling folder in the reconnaissance seat, be provided with detection channels and sampling channel along slideway, detection channels inner slide both sides are respectively equipped with radioactive source and detector, both are on the same axis, be respectively equipped with sampling sleeve and outlet nozzle in the slideway both sides in the sampling channel, the axis of the axis of sampling sleeve and the inner chamber of outlet nozzle is on the same straight line, in the fixed cover that the sampling sleeve slidable fit is installed on the reconnaissance seat, sampling sleeve is equipped with outward the back-moving spring of sampling sleeve to the pushing of slideway direction, and sampling head is equipped with in the outer end of sampling sleeve.This device centralized procurement sample, measure in one, effectively prevented the dust releasing phenomenon that causes with the filter membrane of dust because of long distance moving, thereby reduced the measurement personal error, reduced the running time, reading out data is in time monitored dust concentration fast.Yet still there is following defective in this scheme: all are automatic operations from sampling measurement, can't manually again appraise and decide measurement result; In addition, in the situation that sampling area and test area are equal to, the sampling area quality occurs and overflow, humidity is higher in the flue dust, has affected the detection to the flue dust quality;
Summary of the invention
