The net gas stop valve 2 of corresponding denitration chamber is first shut off, opens corresponding Thermal desorption wind regulating valve 12, high temperature pyrolysis analysis wind passes through heat
Parse wind nozzle 8 uniformly to spray into denitration chamber, it is transversal that Thermal desorption wind is uniformly distributed in denitration chamber under the action of airflow uniform distribution plate 3
Face, the ammonium hydrogen sulfate for being adhered to 4 surface of SCR catalyst is decomposed by high temperature pyrolysis analysis wind, 4 surface of purification SCR catalyst, makes
The regeneration of SCR catalyst 4 is so as to improve denitration efficiency；When the neat stress temperature that temperature sensor 13 monitors reaches the setting value upper limit
When, illustrate that the SCR catalyst 4 of the denitration chamber has recovered good catalytic states by thorough parsing, can close at this time pair
The Thermal desorption wind regulating valve 12 answered, reopens the SCR catalyst Thermal desorption process that net gas stop valve 2 completes corresponding denitration chamber.
Each denitration chamber is separately monitored, and is respectively completed the Thermal desorption of SCR catalyst 4 as needed, and a denitration chamber progress SCR is urged wherein
During 4 Thermal desorption of agent, the normal work of other denitration chambers, system normal operation are not influenced.
4th, jetting deashing flow is as follows：
When pressure value of the system resistance higher than setting, the indoor cloth bag of each dedusting 14 is carried out at jetting deashing successively
Reason.The corresponding dust and gas stop valve 1 of 1# dirt pockets is first shut off, opens corresponding injection system 15, according to conventional bag-type dust
The jetting deashing program of device carries out jetting deashing to cloth bag 14, and unlatching 1# dirt pockets are corresponding after completing 1# dirt pocket jetting deashings
Dust and gas stop valve 1,1# dirt pockets can be with normal uses.Then jetting deashing processing is carried out according to above-mentioned flow to 2# dirt pockets,
2# dirt pockets carry out jetting deashing to remaining dirt pocket successively after completing jetting deashing.
5th, off-line maintenance flow：
If it was found that during a certain dirt pocket operation irregularity, first by the corresponding dust and gas stop valve 1 of the dirt pocket, net gas stop valve
2nd, ammonia regulating valve 11 and Thermal desorption wind regulating valve 12 are adjusted to manual mode by machine (each valve are all provided with hand-electronic switching dress above
Put), manually close each valve above.The head cover for being then turned on the dirt pocket carries out off-line maintenance to the dirt pocket.Complete inspection
By the corresponding dust and gas stop valve 1 of the dirt pocket, 12 weight of net gas stop valve 2, ammonia regulating valve 11 and Thermal desorption wind regulating valve after repairing
Electric control state newly is adjusted to, which can normal use.
The above, is only the preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality
New technical solution and its design is subject to equivalent substitution or change, should be covered within the scope of the utility model.
