Suspension solution filter sieve basket for use in flue gas desulphurization

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.
