Description
Technical field:
The utility model relates to a kind of measurement mechanism that is used for the water capacity of measurement gas pollution source flue gas in the environmental monitoring field.
Background technology:
In the environmental monitoring field,, mainly be meant sampling and analysis to the various objectionable impuritiess of fixed-contamination source emissions such as flue, throat and aiutage to the monitoring of pollution source.These objectionable impuritiess had both comprised solid-state flue dust and dust, also comprised the various objectionable impuritiess of gaseous state and aerosolized.The leading indicator of weighing the pollution source pollution level has: one, emission of harmful substances concentration; Two, emission of harmful substances amount; Three, discharge amount of exhaust gas.Emission of harmful substances concentration and emission of harmful substances amount represent with the dry gas of (temperature is 0 ℃, and atmospheric pressure is 101.3KPa) under the standard state that generally humidity of flue gas is the important parameter that calculates emission of harmful substances concentration and emission of harmful substances amount.In Dec nineteen ninety, the China Environmental Science Press has published " air and waste gas method for monitoring and analyzing " book, the 331st to 335 page of assay method and corresponding measurement mechanism that discloses three kinds of humidity of flue gas of this book: 1. gravimetric method; 2. condensation method; 3. measurement with wet.
Gravimetric method is to extract the flue gas of certain volume from flue, make it by the moisture absorption pipe of hygroscopic agent is housed, steam in the flue gas is absorbed by hygroscopic agent, and the weightening finish of moisture absorption pipe is the vapour quantity for containing in the known volume flue gas both, can calculate the water capacity of flue gas by this vapour quantity.There is the shortcoming of following several respects in gravimetric method: one, when selecting hygroscopic agent, must selection only absorb the steam in the flue gas, do not absorb the hygroscopic agent of other gas, improper if hygroscopic agent is selected, other objectionable impurities that will measure together absorbs, and makes measurement result produce bigger error; Two, measure front and back and all will weigh to the moisture absorption pipe, and will tear open at the enterprising luggage of entire measuring device the moisture absorption pipe, complicated operating process can not realize automatic measurement; Three, humidity of flue gas need manually calculate by the vapour quantity that contains in the known volume flue gas, and the water capacity that calculates can not be converted to electric signal and be used for calculating automatically emission of harmful substances concentration and emission of harmful substances amount.
Condensation method is the flue gas that extracts certain volume, makes it by condenser, adds the steam vapour amount that contains from the saturated gas of condenser discharge according to the water yield that condenses, and determines the water capacity of flue gas.Need constantly to add cold water or frozen water in the condenser in 333 pages in " air and waste gas method for monitoring and analyzing ",, make the steam coagulation in the flue gas become aqueous water to reduce the temperature of flue gas.The water that condensation goes out in the condenser need be measured weight with graduated cylinder.There is following shortcoming in condensation method: if an employing cold water need constantly feed round-robin cold water as condensate water in condenser, support equipment is comparatively complicated; If two adopt frozen water as condensate water, need the one end time of interval just in condenser, to add ice cube equally, otherwise can not realize continuous condensation; Three, no matter be to adopt cold water or adopt frozen water as condensate water, the temperature of its condensation can only reach 0 ℃, and condensation effect is bad; Four, after the water that comes out of condenser condenses need be measured volume with graduated cylinder, calculate weight again, just can be used to calculate the water capacity of flue gas, complicated operating process can not realize automatic measurement; Five, humidity of flue gas need manually calculate by the water yield that condenses in the condenser, and the water capacity that calculates can not be converted to electric signal and be used for calculating automatically emission of harmful substances concentration and emission of harmful substances amount; Six, because sampling pipe has only carried out once filtering, and filter effect is relatively poor, have the part flue dust and enter in the condenser, these flue dust are mingled in the water that condenser condenses comes out, and influence the accuracy of measurement result.
Measurement with wet be flue gas with certain velocity flow overdrying, wet bulb thermometer, according to do, the reading of wet bulb thermometer and the flue gas absolute pressure at measuring point place, determine the water capacity of flue gas.There is following shortcoming in measurement with wet: one, the gauze of parcel wet bulb must be soaked in water, therefore needs constantly supplementing water in the container that is filled with water, otherwise can not realize continuous coverage; Two, the error of Ce Lianging is bigger; Three, humidity of flue gas needs manually to calculate according to dry-bulb temperature and the wet-bulb temperature measured, and the water capacity that calculates can not be converted to electric signal and be used for calculating automatically emission of harmful substances concentration and emission of harmful substances amount.
Summary of the invention:
The technical problems to be solved in the utility model is, existing humidity of flue gas measurement mechanism need manually calculate water capacity, and the water capacity that calculates can not be converted to electric signal and be used for calculating automatically emission of harmful substances concentration and emission of harmful substances amount.For solving this technical problem, the utility model is by the following technical solutions: flue dust water capacity measurement mechanism, comprise condenser 1 and aspiration pump 12, condenser 1 has air intake opening 2, gas outlet 3 and water delivering orifice 4, and the air intake opening of aspiration pump 12 is communicated with the gas outlet 3 of condenser 1; Its special character is: the water delivering orifice 4 of condenser 1 is communicated with water column tube 6; The lower end of water column tube 6 is equipped with pressure transducer 11, and the output terminal of pressure transducer 11 is connected with data processing circuit.
