The nozzle portion 23 is nested within the nozzle casing 3. The nozzle portion 23 is provided with a nozzle.
When the waste gas treatment spraying system works, the loose joint ball valve 21 is in an open state, and sprayed liquid medicine flows out of the circulating water tank, flows into the connecting pipeline of the pluggable spraying device 2 and the nozzle part 23 through the loose joint ball valve 21, and is finally sprayed out from the nozzle of the nozzle part 23, so that the spraying effect is realized.
The spray tower 1 of an exhaust gas treatment spray system is generally equipped with a plurality of nozzle jackets 3, as well as with an adapted pluggable spray device 2. When maintenance is carried out, if the nozzle is blocked, the loose joint ball valve 21 can be closed firstly, and then the loose joint ball valve 21 and the connecting pipeline are separated. After separating the ball cock 21 and the connecting line, the nozzle portion 23 can be pulled out of the nozzle casing 3 together with the connecting line (the connecting line is not located in the nozzle casing 3). Because the tower inside the spray tower 1 is in a negative pressure state, the liquid medicine sprayed out from other nozzles in the tower generally cannot flow out from the opening of the nozzle sleeve 3.
