Abstract
A smoke oxygen and water content continuant testing device comprises an oxygen analysis probe and a sample tube, a filter, a condensation dehydration device, an air pump, a flow limiting device and an electromagnetic valve which are series connected in turn through a windpipe, wherein the sample terminal of the sample tube is inserted into a tested smoke passage, and the other terminal of the electromagnetic valve connects with a demarcating opening of the oxygen analysis probe. The utility model has the advantages that it utilizes traditional oxygen analysis probe to respectively test the content of water and oxygen collected directly from the smoke passage and that of the oxygen after dehydrated and can obtain the water content of the smoke after simple computation with simple conformation and convenient employment, thereby meeting the need of simultaneous testing of oxygen and water content.
Description
Technical field
The utility model relates to the continuous measuring device of exhaust gas components in a kind of flue, specifically is that a kind of flue gas contains oxygen and water cut continuous measuring device, can be widely used in the continuous monitoring of oxygen level and water cut in the fixed-contamination source emission tail gas.
Background technology
The measuring principle that the utility model adopts is traditional zirconia oxygen determination principle, and present most of analysis of oxygen content instruments all adopt the method, and this method belongs to common practise, no longer repeats here.
Traditional analysis of oxygen content instrument can only be measured the oxygen level in the flue gas, can not satisfy and finish the demand of measuring water cut in the measurement gas oxygen level.
Summary of the invention
The purpose of this utility model just provides a kind of flue gas and contains oxygen and water cut continuous measuring device, to solve the problem that can not measure oxygen level and water cut simultaneously that prior art exists.
The technical solution of the utility model is: comprise the oxygen analyzer probe, also comprise the stopple coupon, filtrator, condensation de-watering apparatus, air pump, current-limiting apparatus and the solenoid valve that are connected in series by tracheae order successively, the sampling end of stopple coupon inserts in the measured flue, and the other end of solenoid valve is connected with the demarcation mouth of described oxygen analyzer probe.
Described condensation de-watering apparatus can adopt mechanical condensation de-watering apparatus or electricity refrigeration to coagulate de-watering apparatus.
Described oxygen analyzer probe is zirconia sensor.
The utility model has the advantages that the probe that utilizes traditional oxygen analyzer is measured the content of the moisture oxygen of directly gathering from flue respectively and through the content of the oxygen after dewatering, through calculating the water cut that can obtain flue gas simply, simple in structure, easy to use, satisfied the demand of measuring oxygen level and water cut simultaneously.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the general structure synoptic diagram of the utility model relative section.
Embodiment
Referring to Fig. 1, of the present utility model to the effect that on the basis of traditional oxygen analyzer device, increase a stopple coupon 2, filtrator 3, mechanical condensation de-watering apparatus or electricity refrigeration are coagulated 4, one sampling air pumps of de-watering apparatus 5,6, two-position two-way solenoid valves 7 of current-limiting apparatus (as throttling valve).The sampling end of stopple coupon 2 inserts in the measured flue 8.Stopple coupon 2 is connected in series with filtrator 3, condensation de-watering apparatus 4, air pump 5, current-limiting apparatus 6 and solenoid valve 7 orders successively by tracheae, and the other end of solenoid valve 7 is connected with the demarcation mouth 9 of oxygen analyzer probe 1.
Described oxygen analyzer probe 1 is a zirconia sensor, the host machine part of the not shown oxygen analyzer device of accompanying drawing.
Workflow of the present utility model is as follows:
During normal use, oxygen analyzer probe 1 inserts in the flue 8, monitors the oxygen level in the former flue gas in real time.Aspiration pump 5 continuous workings are extracted former flue gas out continuously by stopple coupon 2, after filtration unit 3 dedustings, enter condensation de-watering apparatus 4, and the flue gas after condensation dewaters is stand-by.When needing to measure the flue gas water cut, only need to connect solenoid valve 7, the flue gas after dewatering just can be through current-limiting apparatus 6, and the demarcation mouth 8 by oxygen analyzer probe 1 enters the analysis cell that is arranged in probe 1 inside.At this moment, oxygen analyzer is output as the dewater oxygen level of back flue gas of condensation, that is to say, before and after solenoid valve 7 was connected, the output of oxygen analyzer was respectively the former flue gas oxygen content and the oxygen level of flue gas by dehydration.By these two output valves, can calculate water cut in the former flue gas by following formula.
In the formula: H is the absolute water content in the former flue gas; X is the oxygen level in the former flue gas; Y is the oxygen level in the flue gas after condensation dewaters.
