DETAILED DESCRIPTION

[0011] The utility model is further explained in detail in connection with the drawings and examples below, but the utility model is not limited to the following implementation.

[0012] In Figure 1 Among them, the deamination tower system for semi coke wastewater treatment of the embodiment includes deamination tower 1, and the inside of deamination tower 1 is sequentially from top to bottom feed zone, reaction zone, heating zone. The tower wall of the heating zone of deamination tower 1 is connected with reboiler 8 and main steam inlet pipe 12, reboiler 8 is connected with reboiler steam inlet pipe 11, and the tower wall of the reaction zone of deamination tower 1 is connected with side steam output pipe. Semi coke wastewater enters deamination tower 1 through feed zone, wastewater enters reaction zone, and reaction zone is located below feed zone. Wastewater is contacted with steam, steam transfers harmful substances such as ammonia nitrogen in wastewater from liquid phase to gas phase through stripping effect, and wastewater continues to flow downward and enters heating zone. High-temperature steam is introduced into heating zone through reboiler 8 to heat wastewater. The temperature in heating zone rises, further promotes the stripping and separation of harmful substances such as ammonia nitrogen, and separated waste liquid flows out through the liquid outlet at the bottom of heating zone.

[0013] The pressure transmitter 7 is installed on the side wall of the heating zone of the deamination tower 1 in this embodiment, which is used to monitor the pressure change of the heating zone of the deamination tower 1 in real time. The pressure transmitter 7 is located above the reboiler 8, and the pressure display alarm 2 is installed on the top of the deamination tower 1. The top of the deamination tower 1 is used to discharge ammonia gas, and the pressure display alarm 2 is used to monitor the pressure change of the top area in real time and alarm in time when the pressure is abnormal. The flow display controller I 4 and the flow control valve I 5 are installed on the side steam output pipe in sequence along the fluid flow direction. The flow display controller I 4 is used to display the steam flow in real time, and the flow control valve I 5 is used to accurately adjust the steam flow according to the instruction of the flow display controller I 4. The pressure transmitter 7, the pressure display alarm 2, the flow display controller I 4 and the flow control valve I 5 are electrically connected. The pressure transmitter 7 transmits the monitored pressure signal to the pressure display alarm 2 and the flow display controller I 4. The pressure display alarm 2 judges according to the preset pressure range. If the pressure exceeds the normal range, the pressure detection alarm immediately issues an alarm. The flow display controller I 4 and the flow control valve I 5 on the side steam output pipe automatically adjust the steam flow according to the signals of the pressure transmitter 7 and the pressure detection alarm, to ensure the stripping effect in the reaction zone and the stability of the tower pressure.

[0014] The liquid level display controller 6 is installed on the lower side wall of the heating zone of the deamination tower 1 in this embodiment, which is used to monitor the liquid level in the heating zone in real time. The flow display controller II 10 and the flow control valve II 9 are installed on the reboiler steam inlet pipe 11 in sequence along the fluid flow direction. The flow display controller II 10 and the flow control valve II 9 are electrically connected with the liquid level display controller 6, and automatically adjust the steam flow according to the signal of the liquid level display controller 6.

[0015] When the liquid level is too high, the liquid level display controller 6 will send a signal. After receiving the signal, the flow display controller II 10 controls the flow control valve II 9 to reduce the steam flow, thereby reducing the liquid level. When the liquid level is too low, the liquid level display controller 6 will send a signal. After receiving the signal, the flow display controller II 10 controls the flow control valve II 9 to increase the steam flow, thereby increasing the liquid level. This linkage control of liquid level and steam flow ensures the stability of the liquid level in the heating zone, and provides a stable environment for the deamination reaction.

[0016] The temperature transmitter 3 is installed on the side wall of the feeding zone and the reaction zone of the deamination tower 1 in this embodiment, which is used to monitor the temperature change in the deamination tower 1 in real time.

[0017] This embodiment realizes real-time monitoring and collaborative control of multiple key parameters such as temperature, pressure and flow in the deamination tower 1 system. The parameters cooperate and restrict each other, ensuring that the deamination tower system operates in a stable state, and improving the stability and reliability of the system.
