Description
Technical field
A kind of boiler exhaust gas flue dust carbon testing device relates to a kind of device of boiler exhaust gas flue dust carbon determination process.
Technical background
What of carbon content in the boiler exhaust gas flue dust directly react the boiler combustion position, the carbon content height, the proof boiler combustion is insufficient, increases coal consumption, has improved the boiler operatiopn cost, be unfavorable for the economy of power plant safe operation, the boiler exhaust gas flue dust carried out the carbon content measurement seem particularly important.
Detect in real time the content of carbon in the flue dust, can rapid reaction boiler combustion operating mode, will help: (1) in time correct coal-air ratio of adjusting, improve the boil combustion control level.(2) rationally control carbon content in the flue dust, can reduce cost of electricity-generating.(3) help to analyze boiler combustion efficiency, improve the security of combustion system.At present, for important parameter so, go back neither one and walk to effective measuring method.The much more general chemical examination modes that adopt detect, and the mode of chemical examination detects and exists sampling difficult, and waste of manpower such as can not monitor in real time at disadvantage.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, provide a kind of simple to operate, efficiency of measurement is high, effectively for adjusting coal-air ratio, improve the boil combustion control level, reduce cost of electricity-generating, the boiler exhaust gas flue dust carbon testing device of data being provided for the security that improves combustion system.
The purpose of this utility model is achieved through the following technical solutions.
A kind of boiler exhaust gas flue dust carbon testing device is characterized in that its structure comprises:
Sample case---this Material collecting box for harvesting is one to have the seal case of gas approach;
The mouth of pipe and the sample case gas approach of three UNICOM's cavitys---this three UNICOMs cavity are affixed;

During operation, flue dust in the flue is collected in the sample case by stopple coupon, (two interelectrode distances are fixed to insert the stainless steel potential electrode above control of dust sample case, the flue dust height is fixed), can the value of having a resistance between the two poles of the earth, it along with the flue dust carbon content what and change, the carbon content display instrument that forms by the resistance monitor transformation can show carbon content then.
Adjusting process: open solenoid valve A, flue dust is entered in the sample case, finish collection and close solenoid valve A behind the sample.Getting flue dust from particle collector chemically examines, result of laboratory test and the comparison of test display instrument data, if result of laboratory test shows consistent with instrument, tester can directly come into operation, if it is inconsistent that result of laboratory test and instrument show, will demarcate display instrument, and adjust adjustable resistance and make measurement result consistent with result of laboratory test.
Using method: close solenoid valve B, C, open solenoid valve A, flue dust enters in the sample case automatically, close solenoid valve A after finishing the collection sample, instrument is measured, and after measurement finishes, opens solenoid valve B, C, allow pressurized air be discharged to the flue dust in the particle collector in the flue or emptying by the ash discharge nozzle, measurement this time finishes.Close solenoid valve B, C, open solenoid valve A, carry out the measurement of next round.
