[0002] The flue gas emitted by coal combustion contains a certain amount of harmful gases such as sulfur dioxide and fine dust particles. Direct emission into the atmosphere will cause serious pollution to the environment. Currently, the common flue gas processors are generally spray-type flue gas processors. This type of flue gas processor uses a spray device to spray and purify the flue gas. However, the purification of the flue gas by this kind of flue gas processor is uneven, and it cannot completely remove harmful substances such as harmful gases and fine dust particles in the flue gas. Even if the treated flue gas is discharged into the air, it will still cause pollution to the atmosphere.

This flue gas processor increases the heat exchange speed, reduces the energy loss, and improves the working efficiency of the device by setting baffle plates, fixed-distance pipes and heat exchange pipes.

[0004] Although the above-mentioned prior art solution increases the heat exchange speed, reduces the energy loss, and improves the working efficiency of the device by setting baffle plates, fixed-distance pipes and heat exchange pipes, it still has the following defects: the flue gas treatment equipment has a poor treatment effect on flue gas, and the filtering equipment used is single, and the filtering equipment cannot be replaced and cleaned during the use of the flue gas treatment equipment.

[0005] In view of this, we propose a combustion flue gas processor with good dust removal effect. Utility Model Content
