The upper part of the catching box 41 is provided with an observation hole, and the dust deposition condition in the box body is observed.

The working process of the combined spark catcher is as follows:

the flue gas passes through the dust inlet pipe 1 and is cooled by the spark particles in the spraying device section. Then the water vapor and large particle sparks in the smoke dust are settled in the cyclone cylinder 3 for the first time and then enter the spark catching device 4 for the second time. The smoke dust collected by the sparks enters the bag-type dust collector for purification, the temperature of the smoke gas can be effectively reduced, sparks in the smoke dust are reduced, and the bag is prevented from being burnt.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
