Zirconium oxide analyzer

Abstract

The present invention discloses a zirconium oxide analyzer, a plurality of points of gases to be measured is connected to the electromagnetic valve through a copper pipe, a plurality of points of electromagnetic valve is assembled to a pipeline, the gas in the pipeline enters into the zirconium oxide pipe in the heating furnace and is outputted by the suction pump when the flowmeter has controlled the flow capacity of the gas; when the electromagnetic valve and suction pump begin to work simultaneously, the temperature controlled instrument heats the electric heating furnace filled with zirconium oxide pipe, at this time the oxygen potential generated by the zirconium oxide pipe is inputted into the controller after the amplifying processing of the data collecting module, the controller executes calculating and processing to the collected signal and at last outputs the calculated result to the display. In the invention the operation is convenient and the running is reliable, when the operator inputs the atmosphere value into the device according to the technological requirement the device can automatically circulating-monitors timely and records the testing result at the condition of not being observed by man.

Description

technical field [0001] The invention relates to an atmosphere monitoring instrument, in particular to a zirconia analyzer capable of automatic and timing patrol monitoring day and night and recording detection results under the condition that no one is guarding it. Background technique [0002] At present, companies that need atmosphere monitoring instruments have to invest a large amount of money to repeatedly purchase oxygen analyzers every year. Judging from the ZO-502 zirconia oxygen analyzer used, its working process and existing shortcomings are as follows: 1. Working process It is: the gas to be measured is connected to the input port of the instrument through a rubber hose, enters the zirconia tube with a heating furnace, controls the flow of the gas through a glass rotameter, and then outputs it through an air pump. The potential generated by the thermocouple in the heating furnace is amplified by OP07 and the oxygen potential generated by the zirconia tube is input...

2. Disadvantages of the current oxygen analyzer: (1) Only one point can be detected at a time, and the air source needs to be switched manually for each point; (2) Special personnel must be set up for testing; (3) When switching the trachea, the air is easy to Enter the trachea, and wait for a certain period of time after the air in the trachea is replaced; (4), the internal curve modification range is narrow, and the zirconia tube cannot be used if it is slightly oxidized, which increases the maintenance cost; (5), the accuracy is not good High and unstable, generally it is difficult to detect traces after half a year of use; (6), the response time of the instrument is slow; (7), the monitoring data cannot be automatically recorded, and manual recording is required
