In the present invention, the processing method of the second rotary valve gas leakage are as follows: the flue gas that will leak to second conveyor is taken away,
And avoid flue gas from entering second conveyor condensation post-etching second conveyor, and then flue gas is avoided to enter the second dust pelletizing system, it makes
Corrode at the second dedusting pipeline blockage and the second dust pelletizing system;Meanwhile it being conveyed by the second foreign gas conveyance conduit
Corresponding air quantity is mixed with the flue gas to be leaked, to avoid air draft pipeline (pipeline that conveying will reveal flue gas) because of flue gas condensing
Clog occurs for moisture condensation.In addition, the flue gas to be leaked and the gas of the second foreign gas conveyance conduit conveying pass through original together
Smoke conveying duct enters adsorption tower and carries out purified treatment, decreases pollution of the discharge to environment of flue gas.

Flue gas in adsorption tower is stopped to leak in second conveyor due to the deformation of the second rotary valve, has also ensured and extract air quantity
Reasonability.
Since high temperature active charcoal in cooling section and cooling wind carries out indirect heat exchange, the analytically cooling of tower in Analytic Tower
The temperature of the cooling wind of section gas vent discharge is higher, is 100~130 DEG C.In view of pipeline radiates, the present invention is set by adjusting
Set the 4th valve on the second foreign gas conveyance conduit, come control extraction Analytic Tower cooling section gas vent cooling wind
Air quantity so that Analytic Tower outlet cooling wind and to leak to the mixed mixed gas of both flue gases of second conveyor
Temperature is higher than the acid dew point of mixed gas, the i.e. gas of the second foreign gas conveyance conduit conveying and the flue gas of the 4th pipeline
The temperature of the mixed mixed gas of the two is higher than the acid dew point of mixed gas, so that air draft pipeline be avoided to condense because of flue gas condensing
Clog occurs.
According to relational expression, the acid dew point of flue gas(its
In,For the concentration of vapor in the flue gas of the 4th pipeline (L6) conveying, %;For the cigarette of the 4th pipeline (L6) conveying
The concentration of sulfur trioxide, % in gas), it is known that the acid dew point of flue gas is related with the content of vapor in flue gas and sulfur trioxide, when
After the flue gas to be leaked is mixed with the cooling wind that Analytic Tower exports, the content of vapor and sulfur trioxide is reduced in mixed gas,
Correspondingly, the acid dew point of gas reduces after mixing.Therefore, to avoid air draft pipeline that clog occurs because flue gas condensing condenses,
The acid dew point that the 4th valve makes the temperature of mixed gas be higher than mixed gas is adjusted, and the acid dew point of mixed gas is lower than wanting
The acid dew point of fume leakage then only needs to adjust the 4th valve and the temperature of mixed gas is made to be higher than the acid dew point that reveal flue gas
, i.e. the mixed mixed gas of both flue gases of gas and the 4th pipeline that the second foreign gas conveyance conduit conveys
Temperature be higher than the 4th pipeline flue gas acid dew point.

It is measured by the second online flue gas analyzer of active carbon flue gas purification system.Second online flue gas analyzer is arranged in adsorption tower
Feeding pipe on, measure the concentration of sulfur dioxide in flue gas and vapor at the position, that is, measure and will leak to
The concentration of sulfur dioxide and vapor in the flue gas of two conveyers.Concentration by measuring sulfur dioxide in flue gas can acquire
The concentration of sulfur trioxide in flue gas, so that the acid dew point that will leak to the flue gas of second conveyor be calculated.Adjust second
The 4th valve on foreign gas conveyance conduit controls the cooling air quantity of the Analytic Tower outlet of extraction, so that the temperature of mixed gas
Degree is that the reading of the thermometer on the 5th pipeline is greater than the acid dew point for wanting fume leakage, to avoid air draft pipeline because of flue gas condensing
Clog occurs for moisture condensation.
In the present invention, the method for handling the second rotary valve gas leakage may also is that the 4th pipeline drawn from feeding pipe
Through being connected to former smoke conveying duct by the 5th pipeline after merging with both the second foreign gas conveyance conduits.Second foreign gas
Conveyance conduit is not connect with Analytic Tower cooling section gas vent, directly transports diluent gas (such as air) dilution cigarette to be leaked
Gas.The present invention is by adjusting the 4th valve being arranged on the second foreign gas conveyance conduit, to control conveying diluent gas
Air quantity, so that the mixed gaseous mixture of both the cold wind of the second foreign gas conveyance conduit conveying and the flue gas of the 4th pipeline
The acid dew point of body is lower than environment temperature, to avoid air draft pipeline that clog occurs because flue gas condensing condenses.
It is lower than environment temperature according to the acid dew point of mixed gas, the cold of the second foreign gas conveyance conduit conveying can be acquired
Extension rate n2 of the wind to the flue gas of the 4th pipeline.Since the content of CO in flue gas is relatively fixed, and in atmosphere substantially not
Containing CO (or the content of CO is few), can be ignored, thus in mixed gas CO concentration CCO2' it is the 4th pipeline
Flue gas in CO concentration CCO2Concentration after n2 times of dilution, i.e. CCO2'=CCO2/n2.It adjusts on the second foreign gas conveyance conduit
The 4th valve, control the air quantity of transporting cold wind so that the reading of the second carbon monoxide detector on the 5th pipeline be CCO2', thus real
The acid dew point of existing mixed gas is lower than environment temperature, avoids air draft pipeline that clog occurs because flue gas condensing condenses.
Further, since CO in flue gas2Content it is also relatively fixed, and CO in atmosphere2Content it is also very low, be 0.03~
0.04% (volume ratio), can be ignored.Therefore, in the third embodiment of the invention and the 4th kind of embodiment,
The second detection device being arranged on 5th pipeline replaces with the 2nd CO2The technical solution equally may be implemented in detector.
In the present invention, the concentration of sulfur dioxide in flue gas of the 4th pipeline and the concentration of vapor and
CO in the flue gas of four pipelines (or CO2) concentration, be by the second online flue gas of active carbon flue gas purification system point
Analyzer measures.
In the present invention, the frequency of the blower motor of the second dust pelletizing system can be shown by blower motor itself and be obtained.

Flow.Second pressure meter is used to detect the pressure value that gas circulates in second conveyor.4th pipeline is used for will be above rotary valve
The flue gas that will be revealed is delivered to former smoke conveying duct, avoids the leakage of the second rotary valve.Second foreign gas conveyance conduit
For mixing with the flue gas in the 4th pipeline, the 5th pipeline of merga pass is to former smoke conveying duct after mixing.Outside second
Carry out the temperature that gas is used to adjust mixed gas in the 5th pipeline, so that the temperature of mixed gas is higher than the acid dew of the mixed gas
Point temperature;Or the acid dew-point temperature of mixed gas in the 5th pipeline is adjusted, so that the acid dew-point temperature of mixed gas is lower than ring
Border temperature;So as to avoid conveying mixed gas pipeline there is a situation where corrode.

Clog occurs.
According to relational expression, the acid dew point t of flue gasld2':
(wherein,
For the concentration of vapor in mixed gas, %;For the concentration of sulfur trioxide in mixed gas, %), it is known that flue gas
Acid dew point is related with the content of vapor in flue gas and sulfur trioxide, when the cooling wind of the flue gas to be leaked and Analytic Tower outlet is mixed
After conjunction, the content of vapor and sulfur trioxide is reduced in mixed gas, correspondingly, the acid dew point of gas reduces after mixing.Therefore,
To avoid air draft pipeline that clog occurs because flue gas condensing condenses, to adjust the 4th valve and the temperature of mixed gas is higher than
The acid dew point of mixed gas, and the acid dew point of mixed gas is lower than the acid dew point for wanting fume leakage, then only needs to adjust the 4th valve
