Abstract
The utility model relates to a sulfur dioxide automatic digital monitoring and testing instrument which is used for industrial boilers and heating furnaces. The utility model is characterized in that the entire sulfur dioxide automatic digital monitoring and testing instrument is split into two sections; a front-arranged which is arranged on one side of a chimney comprises a flue gas sampling tube, a filter, a sucking pump, a sulfur dioxide sensor and a signal amplifying circuit board; a postpositional part comprises a power board, a master control board and an LED display board. The front-arranged and the postpositional parts are connected with a cable under the control of a shielding instrument. Due to the fact that direct amplification is converted into electrical signals to be outputted, the reliability of the whole instrument is reinforced, and artificial damages are reduced. The utility model has the advantages of high anti-interference capability and simple structure.
Description
The utility model relates to the sulphuric dioxide fields of measurement, is used for the content of sulfur dioxide monitoring of Industrial Boiler, flue flue gas specifically.
Along with economy constantly develops, atmospheric envelope is subjected to that sulfur dioxide pollution is corresponding to be increased, to the more attention of this environment friendly system, for a bit, sulfur dioxide in flue gas is measured in domestic employing, is generally monitored with traditional chemical iodimetric titration, this complicated operation, measurement data is few, and personal error is more.
The purpose of this utility model provides test data directly perceived, and simple in structure easy to use, suction pressure is big, can be installed in the automatic digital monitoring instrument of a kind of disc type sulphuric dioxide on boiler flue and the control panel for a long time.
For finishing the technical scheme that above-mentioned order is taked to some extent: whole instrument is made up of preposition and rearmounted two large divisions, preposition part places chimney one side, sampling pipe inserts chimney, fix by pipe adapter and back up pad, on back up pad, fix preposition table by screw simultaneously, preposition table is by sensor, the sulphuric dioxide transmitter, amplifier section, A/D converter and signal generator are formed, above-mentioned preposition table one end is connected with sampling pipe by gas filter, the other end connects aspiration pump by conduit, and connects sensor through signal amplification and signal converter by conduit.Rearmounted part is connected by shielded cable by the interface of preposition table, and is rearmounted partly by switch board, signal receiver, and single chip microcomputer and light-emitting diode display are formed.
The utility model embodiment in conjunction with the accompanying drawings in addition sample carefully describe.
