[0033] The use method of the present application: First of all, it needs to be clear that the ammonia water preparation equipment involved in the present application is mainly used for the preparation of industrial ammonia water. The present application elaborates the use method by taking the operation in the ammonia water preparation process as an example. When ammonia water needs to be prepared, the working principle and use method are as follows: Working principle: The present application realizes the efficient reaction of ammonia gas and water through the synergistic optimization of the gas inlet system and the rotating spraying system. Liquid distribution principle: The reaction liquid enters the fixed part 510 of the spraying mechanism 500 through the liquid inlet channel 410 and flows into the annular water tank of the liquid guide cylinder 521. The driving motor drives the rotating shaft 522 to rotate, and the liquid in the annular water tank is thrown to the water retaining structure 530 under the action of centrifugal force, atomized through the spraying hole 531, and forms a uniformly distributed droplet group which slowly falls under the action of gravity.

[0034] Gas distribution principle: After the ammonia gas is accelerated through the Venturi tube, it enters the annular pipe and diffuses upward through the 48 evenly distributed gas outlets 312, forming a uniform gas distribution field. The flow limiting effect of the Venturi tube forms a high-speed jet at the outlet, further enhancing the gas disturbance.

[0035] Gas-liquid reaction principle: The falling atomized droplets and the rising ammonia gas form countercurrent contact, greatly increasing the gas-liquid contact area and contact time. The centrifugal force generated by the rotating spraying makes the droplets form a spiral motion trajectory in the chamber, further prolonging the reaction path and promoting the full dissolution of ammonia gas.

[0036] Concentration control principle: The degree of droplet atomization is changed by adjusting the motor speed, and the ammonia gas flow is adjusted by the switch valve 320. The two are cooperatively controlled to accurately adjust the ammonia water concentration. During the reaction process, a small amount of ammonia gas that has not completely reacted enters the recovery system through the top exhaust port 700, avoiding waste and pollution.

[0037] Use method: Equipment preparation: Check the sealing of each connection part to ensure that the sealing cover 600 is installed in place Check the pressure of the ammonia gas storage tank (should be kept at 0.2-0.3MPa) Connect the water source to the liquid inlet channel 410 to ensure that the water quality meets the production requirements Turn on the power of the control cabinet and check whether the instruments display normally Parameter setting: According to the required ammonia water concentration, set the motor speed (recommended 20-40r / min) Set the liquid inlet flow (recommended 100-300L / h) Pre-set ammonia gas flow (recommended 0.5-2m³ / h) Start operation: First open the liquid inlet valve, inject the appropriate amount of water into the reaction chamber 210 (to 1 / 3 of the liquid level meter) Start the drive motor, and the spray mechanism 500 begins to rotate Slowly open the ammonia switch valve 320, and according to the preset flow rate, ammonia is introduced Continue to supplement the reaction liquid, and keep the liquid level stable at 2 / 3 of the liquid level meter Operation monitoring: Real-time monitoring of the reaction chamber 210 pressure (should be maintained at 0.05-0.1MPa) Every 30 minutes, sample and detect the ammonia water concentration, and according to the results, fine-tune the ammonia flow rate Observe the exhaust port 700 pressure to ensure that the tail gas treatment system is working normally Product collection: When the ammonia water concentration reaches the set value, open the liquid outlet valve 800 Keep continuous feeding and discharging to maintain a stable production state The collected ammonia water should be sealed and stored in time to avoid ammonia volatilization Shutdown operation: First close the ammonia switch valve 320, continue to introduce the reaction liquid for 10 minutes to absorb the residual ammonia Close the liquid inlet valve, and when the liquid level in the reaction chamber 210 drops to 1 / 4, turn off the drive motor Open the liquid outlet 800, and empty the remaining ammonia water Turn off the main power supply, and clean and maintain the equipment Maintenance: Check whether the spray holes 531 are blocked every week, and if necessary, dredge them Check the sealing performance of the sealing cover 600 every month, and replace the aging sealing elements Every quarter, perform a pressure test on the gas inlet pipeline 310 to ensure that there is no leakage Replace the wear-resistant bushing in the venturi tube every six months The present application improves the contact time of ammonia and water, accelerates the reaction rate, improves the uniformity of ammonia water concentration, greatly reduces the preparation time, improves the ammonia utilization rate, greatly reduces the energy consumption, and is more simple and convenient to operate In addition, it should be noted that in the description of the present application, unless otherwise specified and limited, the terms "installation", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; can be mechanical connection, or electrical connection; can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements.
