1. Filling:
The quality of iron oxide catalyst filling directly affects the actual effect of use, so it must be given full attention. The catalyst filling process should be managed by a full-time person, and the following aspects should be paid attention to:
(1) First lay two layers of stainless steel wire mesh with a mesh size of less than 8-10 mesh on the grate plate of the flue gas desulfurization tower.
(2) Lay a layer of 20-30mm, Φ20-30mm thick coke blocks on the wire mesh.
(3) Because smoke and dust will be generated during the logistics transportation and loading and unloading process, the powder should be screened before filling.
(4) The professional filling equipment used should have a pouring pipe that can be rotated at will so that the material can be evenly filled around the reaction tower. It is not allowed to pour the catalyst from the middle to prevent uneven filling.
(5) The compressive strength of the iron oxide catalyst increases with the increase of sulfur absorption during the use process, so it should be filled in layers in the flue gas desulfurization tower. Each layer is marked according to the height of the catalyst filling to ensure that it is filled fully, leveled and evenly.
(6) During the whole filling process, it is strictly required that the sulfur agent is not directly stepped on. Wood boards can be placed on the material layer before entering to remove the material and check the filling status.
(7) The raw material gas inlet of flue gas desulfurization needs to be equipped with a grate plate or coke blocks to prevent the catalyst from being blown into disorder.
2. Use:
(1) Flue gas desulfurization towers usually do not require professional heating and consume electricity, but outdoor desulfurization equipment must be insulated in winter to prevent the air components from being too cold, reducing the catalytic activity of the catalyst and the accumulation of liquid on the bed, which seriously damages the use.
(2) Before flue gas desulfurization, ways should be found to remove smoke tar and water scum.
(3) The iron oxide desulfurizer can be replaced all at once or in sections according to the direction of gas flow.
(4) Regularly discharge the accumulated liquid in the water separation equipment in front of the flue gas desulfurization tower and the bottom of the flue gas desulfurization tower, and do not allow air to carry liquid into the flue gas desulfurization tower.
(5) Use it smoothly and use it reasonably and effectively to give full play to its good performance indicators.
3. Logistics and transportation:
(1) Iron oxide catalysts should be handled with care during logistics and transportation to prevent shaking and collision to prevent damage.
(2) When storing iron oxide catalysts, they should be prevented from absorption and chemical pollution.
