Sulfur-tolerant shift catalyst loading program

A
Catalyst loading conditions to be satisfied before the matters and confirm
1! Confirm the export of metal mesh collector well,
2, the thermocouple protection tube intact,
3, catalyst unloading pipe blind flange has been reset,
4, the furnace clean, and change the system should ensure a thorough purge blast furnace clean,
5 catalyst loading to setting up a temporary shed,
6, the use of ceramic ball, catalyst, Raschig rings check in advance the number, size and model, check the shift converter grating, wire mesh, debris collector specifications, confirm the correct number of materials,
7, Major bucket, crane and forklift trucks to the scene.
Two
Note when filling
1, the filling in advance to confirm before the start of filling height, and as marked in the furnace,
2, must not make the catalyst balls to fall from a height of 0.6m or more,
3, the device internal operations must be carried out before the gas analysis, that it is safe to wear masks to work.
4, the operator in the furnace work, not directly step on the catalyst, the catalyst spread on the wood to prevent damage, the job is completed, the wood must be used to get out of the furnace.
5, the filling operation, if rain, snow, immediately stop operation, to protect the catalyst does not get wet.
6, when the thermocouple casing around the filling, careful not to overhead.
7, operation, do not put foreign objects into the furnace (iron pins, paper, cigarette butts, dirt, etc.).
8, should be prepared filling records, including materials, specifications, models and materials, filling the number, height, filling the time.
9, until the filling is usually no need for catalyst screening, but in the transport and loading and unloading process, due to improper operation may damage the catalyst, if found worn or broken should be sieved.
Third, the
Filling the order and method
1, the balls of the filling
(1) to draw the height of balls filling with chalk on the mark.
(2) the canvas bag below the funnel connected to the catalyst loading, the furnace operators pull the bag export to avoid balls straight into the following break.
(3) balls paved, confirm to the specified height.
(4) The catalyst must also be installed on the pipe discharged balls.
(5) prefabricated metal wire right in the balls on the ground floor, leaving the catalyst discharge nozzle.
2,
Catalyst loading
a,
Sec catalyst loading
(1) the catalyst into the hanging bucket
(2) transferred to the catalyst loading port cranes, staff from the mouth into the catalyst pre-installed in the mouth of the funnel, into the furnace through the chute into the canvas bag.
(3) filled with a certain catalyst, it should stop loading, the surface bulldozed, filled canvas bag when you want to move, paving the catalyst.
(4)
The required height, the bulldozing of the catalyst surface, the prefabricated wire mesh laid on top of the catalyst.
b, a catalyst loading
(1) - (3) steps above.
(4) calculated by the amount of catalyst loading up debris collector position, and crossed mark in the furnace, when the catalyst loading to the crossed position, the catalyst bulldozed.
(5) debris collector well placed in the furnace, the upper opening sese wood is good, then connect the debris collector
(6) filled with debris collector flush with the catalyst, the catalyst for paving, the cork removed, the prefabricated wire mesh installed on it.
3, Raschig ring packing
(1) at the required position, and marked with chalk.
(2) filled with Raschig rings to the required position bulldozed.
(3) Raschig ring mounting grid.
