Patent ID: 8800778

Claim:
A flue gas desulfurization device comprising at least one suspension solution filter sieve basket disposed in a suspension solution having a flow direction, the at least one suspension solution filter sieve basket comprising: a predetermined breaking point configured to release so as to cause a relief of a force on a sieve basket body when a suction load on the sieve basket body is exceeded; a sieve basket cover disposed on an upper side of the at least one suspension solution filter sieve basket, wherein, after the release, the predetermined breaking point results at least a partial opening of at least a part of the sieve basket cover; and holes, wherein, the least one suspension solution filter sieve basket, upon a breakage at the predetermined breaking point and the partial opening of at least a part of the sieve basket cover, acts as a grid so that a mass of solids is retained and only a part of the solids flow therethrough.
