Description
Technical field
The utility model relates to the processing technology fields of tail gas dust dry in phosphatic compound fertilizer technique, and in particular to a kind of
Phosphorus compound fertilizer dries tail gas dust chamber.
Background technique
It is all to utilize combustion of natural gas in fertilizer enterprises production monoammonium phosphate, Diammonium phosphate (DAP), the production technology of compound fertilizer
Hot-air is generated to dry the product just produced, and take away the moisture content of evaporation, shape into phosphorus compound fertilizer product drying machine
At so-called tail gas, it is discharged to back segment and carries out vent gas treatment.However contain a large amount of powdered fertilizer in tail gas, it cannot directly arrange
It puts.According to national requirements for environmental protection, the particles such as PM2.5 up to standard must could be discharged in the tail gas of discharge, so the processing of back segment
It is comparable complexity.Back segment dedusting includes the processes such as dust chamber dedusting, bag-type dust, electrostatic precipitation.
The defect of the prior art is that in traditional cleaning dust technique, because the cell structure that gathers dust is simple, tail gas is along straight
Line direction directly passes through dust chamber, and the speed that tail gas flows through quickly, causes under the chemical fertilizer dust and spraying device spray in tail gas
Fog insufficient contact causes dust chamber dust removal process ineffective, increases the difficulty of subsequent processing, if subsequent processing power
Degree not enough, is then easy to cause exhaust emissions exceeded.
Utility model content
In view of at least one defect of the prior art, the purpose of the utility model is to provide a kind of dry tail gas of phosphorus compound fertilizer
