Abstract
The utility model discloses a device for measuring the moisture content of the flue gas adopting the condensation weighing method. The device comprises a sampler, a moisture absorption pipe, a mass flowmeter and an air extracting pump, which are connected in series sequentially. The device is characterized by further comprising a condensation pipe, which is placed in a condenser and connected between the sampler and the moisture absorption pipe in series. Through the independent functions of the condensation pipe and the moisture absorption pipe, the flue gas is condensed in the condensation pipe firstly and then enters the moisture absorption pipe; for the reason that most of the moisture in the flue gas is condensed in the condensation pipe, the load of the moisture absorption pipe is small when the flue gas passes through the moisture absorption pipe, and the problem that a sampling air passage is not smooth caused by the agglomeration after a moisture absorption agent absorbs the moisture content is avoided, therefore, more suitable moisture-absorption weight increment can be chosen, that is to say, a given flue gas volume can be appropriately increased, as a result, the device can reduce the error for measuring the specific gravity of the moisture content in the flue gas, further reduce the system error of the measurement, and improve the measuring accuracy.

Background technology
Flue gas water content (smoke moisture) is to survey the factor as an important Gas Parameters in pollution source detect, and whether its accuracy will influence the calculating of fume emission total amount and pollutant levels.
One of existing method of measuring the flue gas water content is exactly gravimetric method (claiming weight method again).Its principle of measuring flue gas moisture content is, the flue gas by extracting certain volume in the flue makes it by the moisture absorption pipe of hygroscopic agent is housed, and the moisture in the flue gas is absorbed by hygroscopic agent, and the weightening finish of moisture absorption pipe is the amount of moisture that contains in the known volume flue gas.The device that existing gravimetric method is measured moisture in the flue gas as shown in Figure 1, by sampling thief, place U type moisture absorption pipe, pressure vacuum gauge, hygrometer, spinner-type flowmeter and the aspiration pump of bosh to be followed in series to form.The flue gas that sampling thief is gathered condensation and moisture (condensate water) in U type moisture absorption pipe are absorbed by hygroscopic agent, thereby obtain moisture in the flue gas by the weightening finish of measuring the moisture absorption pipe.There are following defective in existing gravimetric method and device for carrying out said thereof, the one, in the moisture absorption pipe after the hygroscopic agent moisture absorption caking gas circuit that causes sampling not smooth, influence is measured; The 2nd, cause sampling the not smooth problem of gas circuit in order to overcome because of luming after the hygroscopic agent moisture absorption, can select few moisture absorption weightening finish usually, cause system errors for measurement bigger; The 3rd, be unknown number through the residual moisture content of discharging gas after the hygroscopic agent moisture absorption, do not measure or quantitative identifying.
The utility model content
Problem to be solved in the utility model, be to overcome the defective that prior art exists, provide a kind of condensation weight method to measure the device of flue gas moisture content, two links of condensation and moisture absorption are separated, overcome because of luming after the hygroscopic agent moisture absorption and caused sampling the not smooth problem of gas circuit, thereby can increase hygroscopic capacity, reduce measuring error, improve measuring accuracy.
The utility model condensation weight method is measured the device of flue gas moisture content, is followed in series to form by sampling thief, moisture absorption pipe, dew point hygrometer, mass flowmeter and aspiration pump; It is characterized in that: also be provided with condenser pipe, described condenser pipe places condenser, and described condenser pipe is serially connected between sampling thief and the moisture absorption pipe.
Further improvement project is: after the moisture absorption pipe, be connected in series a dew point hygrometer, be used to measure the residual moisture content through the flue gas of discharging behind the moisture absorption pipe.Can accurate quantification measure through water cut in the flue gas after the condensation moisture absorption and calculate in total amount.
Another improvement project is: install one-level or two-stage discolour silica gel behind the moisture absorption pipe additional, by silica gel suction back variable color degree, the qualitative definite value that provides water cut in the tail gas is used to measure the residual moisture content through the flue gas of discharging behind the moisture absorption pipe, and calculates in total amount.
Separate with the function of moisture absorption pipe by condenser pipe, flue gas is earlier by being embedded in the condenser pipe in the condenser, moisture in the flue gas is condensed into water by major part and is stored in the condenser pipe, and through having the moisture absorption pipe of hygroscopic agent, the moisture in the flue gas is further separated through the gas behind the partial dehydration; Because most of moisture is condensed in condenser pipe in the flue gas, during through the moisture absorption pipe load of moisture absorption pipe little, the caking not smooth problem of gas circuit that causes sampling can not appear after the hygroscopic agent moisture absorption.Flue gas process dew point hygrometer through discharging behind the moisture absorption pipe can accurately measure the residual moisture content of discharging gas what are.Because condenser pipe separates with the function of moisture absorption pipe, can select proper moisture absorption weightening finish fully, promptly suitably strengthen the flue gas volume of setting, reduce the proportion of measuring error in flue gas moisture content, thereby reduce system errors for measurement.
