Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of catalyst for denitrating flue gas cleaning regenerating unit of relating to of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, describe a kind of catalyst for denitrating flue gas cleaning regenerating unit that the utility model relates in detail.
Fig. 1 is the schematic diagram of a kind of catalyst for denitrating flue gas cleaning regenerating unit 1 of relating to of the utility model.As shown in the figure, described catalyst for denitrating flue gas cleaning regenerating unit 1 (hereinafter to be referred as " regenerating unit ") comprises shell 10, rinse bath 20, be fixed on electrical heating and attemperator 30 on described rinse bath 20, be arranged at the basket 21 in described rinse bath 20, is positioned at described basket 21 bottoms the bubble generator 23 being supported by platform 24, air pressurized machine 40 and air conduit 41.
Described basket 21 can directly be placed in rinse bath 20, and preferably described basket 21 passes through support 22 support and connection on the inwall of described rinse bath 20; Described rinse bath 20 is connected as a single entity endways with shell 10, and is formed with cavity 11 between rinse bath 20 and shell 10, and described electrical heating and attemperator 30 are arranged in cavity 11; Described platform 24 is fixed on the inwall of rinse bath 20, described bubble generator 23 is connected with platform 24, described air conduit 41 connects air pressurized machine 40 and platform 24, and by the air input platform 24 after described air pressurized machine 40 pressurizations, and then the air after pressurization enters in bubble generator 23.
For the waste water after cleaning is discharged, described regenerating unit 1 is also provided with floss hole 27 in bottom, and described floss hole 27 is integrally formed with rinse bath 20; For discharging faster waste water, the bottom 25 of described rinse bath 20 is obliquely installed to floss hole 27.
When needs clean fouled catalyst, the denitrating catalyst of poisoning and deactivation first need be purged with compressed air, carry out pre-dedusting, remove a large amount of floating ash in catalyst duct, then will put into described basket 21 through the catalyst of pre-dedusting, and at the interior injection distilled water of described rinse bath 20 until submergence catalyst completely; Finally pass into forced air, utilize bubble generator 23 to produce a large amount of fine and closely woven bubbles from bottom land, and upwards spray, utilize the souring of bubble jet flow, the dirt that catalyst inwall is adhered to cleans, and for reaching better cleaning performance, described bubble generator 23 can arrange any number of, and can, by selecting the bubble generator 23 of different specification size and the pressure of control inputs air, adjust quantity, diameter and the flow velocity of bubble.After cleaning finishes, open floss hole 27 and discharge washes, washes is processed and can be collected reuse through sedimentation.
Decaying catalyst after above-mentioned bubble jet flow washes away is can recovered part active, yet, for recovering to greatest extent the activity of described catalyst, also need further described catalyst to be cleaned.The utility model adopts ultrasonic cleaning solution to carry out the deep clean of catalyst.
