Relative gap it is spraying to generate；Make to block by timing rotation nozzle screw rod simultaneously spray atomizing outlet and frustum of a cone portion it
Between gap calcium sulfate and calcium chloride loosely fall off.
In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions:
A kind of injection calcium hydroxide deacidification device, the spray outer tube including being equipped with spray channels, the spray outer tube are embedded
It is spray atomizing outlet positioned at the inner end of the indoor spray channels of chilling on chilling chamber outer wall, which is characterized in that
Further include nozzle screw rod, spray head outer cover, set internal thread nut；
The nozzle screw rod includes that frustum of a cone portion, integral type are fixed at the screw rod portion of frustum of a cone portion narrow end；
It is covered with outside the spray head and accommodates the through-hole that the screw rod portion passes through；
The spray atomizing outlet is set as with the shape in the truncated cone in frustum of a cone portion；The nozzle screw rod is set to spray
In channel, frustum of a cone portion is located in spray atomizing outlet, between frustum of a cone portion and screw portion are not set between spray channels
Gap, and the tail end in screw rod portion is located at outside the outer end of spray outer tube；The through-hole of the spray head outer cover is placed through spray outer tube
It is fixedly connected behind outer screw rod portion with the outer end of spray outer tube；Screw rod portion also screw thread outside spray head outer cover is screwed with nut,
The nut fitting lid sets residence and states through-hole；Outside quench chamber and close to also setting on the spray outer tube at spray head outer cover
There is calcium hydroxide slurry import.
The spray outer tube is structure as a whole with chilling chamber outer wall.
It is to be threadedly coupled between the spray head outer cover and spray outer tube.
The tail end in the screw rod portion of the nozzle screw rod connects motor using shaft coupling.
Compared with prior art, the present invention structure is simple, design is reasonable；The adjustable section of spray atomizing outlet, guarantees
Most preferably go out mist；Swivel nozzle screw rod can make the calcium sulfate for blocking spray atomizing outlet and calcium chloride loosely to be removed simultaneously,
Guarantee that spray atomizing outlet can spray to continuous effective, it is practical.

Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
Referring to Fig. 1, a kind of injection calcium hydroxide deacidification device, the spray outer tube 1 including being equipped with spray channels, the spray
Outer tube 1 is embedded on chilling chamber outer wall 2, is spray atomizing outlet 4 positioned at the inner end of the indoor spray channels of chilling, feature exists
In,
Further include nozzle screw rod 5, spray head outer cover 3, set internal thread nut 8；
The nozzle screw rod 5 is fixed at the screw rod portion of frustum of a cone portion narrow end including frustum of a cone portion 6, integral type；
The spray head outer cover 3, which is equipped with, accommodates the through-hole that the screw rod portion passes through；
The spray atomizing outlet 4 is set as with the shape in the truncated cone in frustum of a cone portion 6；The nozzle screw rod 5 is set to
In spray channels, frustum of a cone portion 6 is located in spray atomizing outlet 4, frustum of a cone portion 6 and screw portion not with spray channels it
Between set gap, and the tail end in screw rod portion is located at outside the outer end of spray outer tube 1；The through-hole of the spray head outer cover 3 is placed through
