Continuous spraying is also used to produce nano calcium carbonate through carbonization. The steps are to spray Ca(OH)2 slurry from the carbonization tower in a mist form through a pressure nozzle, and at the same time, kiln gas is introduced to fully contact the slurry to react.

The nozzle 19 is easy to be taken out and cleaned by setting a rotatable device with a sealing effect, and the speed at which the nozzle 19 is blocked is slowed down by raising the position of the nozzle 19 and setting an air outlet device for accelerating the falling of the sprayed liquid.

[0025] A magnetic block 8 is provided at the lower position of the revolving door 7, and the outer shell of the carbonization tower 1 is made of metal, which is convenient for fixing the revolving door 7 after closing; a rubber layer 13 is fixedly connected to the outer side of the baffle 12, and the rubber layer 13 and the hole 6 opened in the carbonization tower 1 are tightly fitted to increase the sealing effect of the carbonization tower 1; one end of the threaded rod 10 passes through the revolving door 7, and the handle 11 is set in a round shape in the middle and rod-shaped protrusions at both ends, which is convenient for moving the baffle 12; one end of the connecting pipe 16 passes through the carbonization tower body 1, and there are twelve air outlets 17 in total, which is convenient for accelerating the falling of the atomized liquid.

[0026] Working process: During the operation of the equipment, the external power supply is energized. When the pressurized carbonization device for preparing nano calcium carbonate is used, the carbonization tower 1 is first placed in a suitable position. For the specific working process, reference is made to Patent No. CN206751417U, which discloses a pressurized carbonization device for preparing nano calcium carbonate.

The user reaches into the hole 6, rotates and removes the nozzle 19, and then takes it out of the hole 6 for cleaning and maintenance. The rotatable device with a sealing effect is set to make the nozzle 19 easy to take out and clean. By raising the position of the nozzle 19 and setting an air outlet device that accelerates the falling of the sprayed liquid, the speed at which the nozzle 19 is blocked is slowed down.
