Embodiment 1

[0059] like figure 1 As shown in the figure, the automatic cleaning device for the cooler provided in this embodiment is applied to the negative pressure ammonia steaming equipment to automatically clean the non-condensable gas cooler in the negative pressure ammonia steaming equipment, and the non-condensable gas cooler is the first replacement Heater 1, the first heat exchanger 1 adopts a tubular heat exchanger, the shell side of the first heat exchanger 1 is communicated with the ammonia gas pipeline 34, and the tube side of the first heat exchanger 1 is communicated with the condensing pipeline 32; In the negative pressure ammonia steaming equipment, the vacuum ejection device 24 is communicated with the vacuum device water tank 25, and the vacuum ejection device 24 utilizes the high-speed flow of the liquid to generate the ejection and suction effect, and sucks the non-condensable gas in the ammonia gas pipeline 34 into the first heat exchanger 1 In the middle, the vacuum...

Embodiment 2

[0087] like Figure 5 As shown, this embodiment provides a cleaning control method, which is applied to the automatic cooler cleaning device of Embodiment 1, and is controlled and realized by the PLC controller 100 in the automatic cooler cleaning device, which includes the following processes:

[0088] S1. In the initial state, the first heat exchanger 1 cools the non-condensable gas; the PLC controller 100 controls the fluid in the ammonia gas pipeline 34 to flow along the first heat exchanger 1 through the fifth solenoid valve 7 and the sixth solenoid valve 8 The PLC controller 100 controls the cold fluid in the condensing pipe 32 to enter and exit along the tube side of the first heat exchanger 1 through the first solenoid valve 3 and the second solenoid valve 4, the steam boiler 11 does not work, the single-pass electromagnetic The valve 12 is closed, and both the shell side and the tube side of the second heat exchanger 2 are in an idle state; the operation in the above ...

Abstract

The invention belongs to the technical field of chemical production equipment, in particular to an automatic cooler cleaning device and a cleaning control method thereof. It is used in negative pressure ammonia distillation equipment to automatically clean the non-condensable gas cooler. The non-condensable gas cooler adopts a tube-and-tube heat exchanger, and the shell side of the tube-and-tube heat exchanger is connected to the ammonia gas pipeline. The tube side of the tube-and-tube heat exchanger communicates with the cooling water; the device includes: at least one additional tube-and-tube heat exchanger, at least four electromagnetic valves for the tube side of the heat exchanger, and at least two valves for the shell side of the heat exchanger. Solenoid valves, at least four pressure sensors, at least four temperature sensors, and a PLC controller. The device can effectively solve the clogging problem of the non-condensable gas cooler in the negative pressure ammonia distillation equipment, and can automatically clean without stopping the machine. The cleaning efficiency is high, and the efficiency of the negative pressure ammonia distillation process can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of chemical production equipment, in particular to an automatic cleaning device for a cooler and a cleaning control method thereof. Background technique [0002] Ammonia-containing wastewater is the waste generated in the production process of chemical plants. The treatment of ammonia-containing wastewater is a common problem in the chemical industry. Ammonia process and equipment for harmless treatment of ammonia-containing wastewater. [0003] At present, some chemical companies use the negative pressure ammonia steaming process to treat ammonia-containing wastewater. In this process, the ammonia steaming wastewater is heated by a tubular furnace and depressurized, so that the ammonia steaming wastewater at a certain temperature reaches a supersaturated state to precipitate steam, which is evaporated and evaporated. The gas-liquid separation is completed in the device, the steam enters the ammonia distill...
