Specific embodiment
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawing, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of consumer waste incineration flue gas purification device, comprising: reaction tower 1 and bag filter 2, in the reaction tower 1
Exhaust fan 3 is connected between the bag filter 2；
The following side of the reaction tower 1 offers air inlet 12, and the upper lateral part of the reaction tower 1 offers gas outlet 13, described
The flow channel on flow direction tide is formed between air inlet 12 and the gas outlet 13, the top of the reaction tower 1 is fixedly installed with out
The spray thrower 11 of mouth down；
The bag filter 2 is internally provided with multiple dedusting areas 21, is mounted on filter between the adjacent dedusting area 21
Net 22, and each adjacent strainer 22 is in be spaced apart up and down.
Wherein, the junction of the reaction tower 1 and the exhaust fan 3 is provided with axial screen pipe 4, can not only prevent
Enter in exhaust fan 3 from the particle device contained in the gas flowed out in reaction tower 1, and causes exhaust fan 3 to damage, and can also
The effect for carrying out double purification to gas is enough played, is further ensured that degree of purity when gas discharge.
The bottom of the reaction tower 1 offers waste residue outlet 14, and waste residue collection is placed with immediately below the waste residue outlet 14
Case 15 can effectively be collected waste residue, be convenient for subsequent recycling and reusing.
