Description
Technical field
The utility model belongs to metallurgical coking production technical field, is related to a kind of coke oven flue gas detection device.
Background technique
The fuel that coke-oven plant's coke oven uses irregularly switches over for coke-stove gas and blast furnace gas, in process of coking, meeting
Release a large amount of sulfide, nitrogen oxides and flue dust etc..Stack gases after heating gas burning pass through chimney outlet atmosphere,
Middle pollutant is mainly SO2, NOx, dust particle etc..
2012, China was put into effect " coking chemistry emission of industrial pollutants standard ", in the standard, clear stipulaties " from
From on January 1st, 2015, the discharge amount of conventional coke oven nitrogen oxides in effluent is no more than 500mg/m3, the discharge of sulfur dioxide
Amount is no more than 50mg/m3." new standard in coke oven flue gas nitrogen oxides and sulfur dioxide (SO2) emissions require it is stringenter, especially
It is to be no more than 150mg/m in line city emission limit nitrogen oxides such as " going up north wide "3, sulfur dioxide is no more than 30mg/m3。
Start to carry out the useless cigarette of coke oven for environmental requirement and to the social responsibility of environmental protection, government department and coke-oven plant
The detection of nitrogen oxides and sulfur dioxide in gas, including use is various offline, whether the discharge of online equipment monitoring pollution objects is up to standard,
But most of monitoring tapping equipment is installed at coke oven flue gas chimney, that is, flue gas finally collects emission point, by
It is made of in coke oven more regenerative chamber gas-fireds, therefore this can not the practical flue gas emission situation of accurate evaluation coke oven.In addition,
There is part invention device to carry out flue gas measurement at coke oven regenerator flue, as " transverse direction of coke oven burning waste gas is oxygen-containing for patent
Amount detecting device (CN 201387423Y) ", " a kind of coke oven flue gas oxygen content and nitrous oxides concentration detection system (CN
205280438 U) ", the method (106932349 U of CN) of oven wall of coke oven carbonization chamber blowby " a kind of detect ", but coke-stove gas
Periodically there is commutation in burning, the ignition temperature in quirk is caused to change, and nitrous oxides concentration is mainly in coke oven flue gas
Thermal NO, as coke oven flue gas temperature change difference is more obvious, so either online still offline inspection is set
Standby, final detected value is moment flue gas content, and the coke oven flue gas value detected will appear maximum value and minimum value, wherein most
Before big value appears in ascending air commutation, before minimum value appears in down current commutation, if on-line monitoring equipment detection data
Being depicted as two dimensional plot will appear the concussion distribution situation with wave crest and trough, as shown in Figure 1.
Coke oven flue gas discharge testing result and detection time and commutation cycle, there are much relations.Often appear in rising
Airflow-reversing stage testing result is exceeded, but practical coke oven flue gas pollutant discharge amount is lower, the inspection of down current commutation phase
It is up to standard to survey result, but practical coke oven flue gas pollutant emission is higher, can not accurately measure coke oven flue gas emission behaviour.
Summary of the invention
For the defect of currently available technology, the utility model aim is just to provide a kind of stable measurement coke oven some cycles
Interior flue gas emission situation system, and then coke oven flue gas emission behaviour is preferably evaluated, stablize coke oven flue gas gas componant, improves burnt
The analysis of kiln gas measurement accuracy, the realization multiple regenerative chamber flue gas emission situations of coke oven is compared or more time phase coke ovens
Flue gas emission situation directly compares, and eventually by technique adjustment or scrap build, reduces oven pollutants discharge, realizes coke oven
Flue gas qualified discharge.
The utility model aim is realized by following technical solution:
A kind of coke oven flue gas detection device, it is characterised in that: including coke oven regenerator, coke oven regenerator is connected by gas collecting tube
Collection air pump is connect, the other end for collecting air pump is connect with the uniform and stable room of gas, and the uniform and stable room of gas is connected with the vacuum vacuumized
Pump, the uniform and stable room of gas also passes through piping connection with flue gas inspection device；Coke oven regenerator and gas collecting tube, collection air pump and gas
It is set respectively between uniform and stable room, the uniform and stable room of gas and the uniform and stable room of vacuum pump, gas and coke oven flue gas detection device
There is valve.
The coke oven flue gas detection device is controlled by automatic electrical control system.
The coke oven flue gas detection device stablizes coke oven flue gas gas componant, improves coke oven flue gas measurement accuracy, realizes burnt
The analysis of the multiple regenerative chamber flue gas emission situations of furnace is compared or more time phase coke oven flue gas emission behaviours compare, and is improved burnt
The evaluation comparativity of kiln gas detection.
