A methanol workshop circulating water utilization system is shown in a combined figure 1 and comprises river channel treatment water 1, condensate 2, a circulating water pool 3, a storage tank 4, a converging flow divider 5, a liquid level meter 6, a top end bent pipe 7, a fog gun pump 8, a safety valve 9, a water return pipe 10, a first pipeline 11, a second pipeline 12, a third pipeline 13 and a side filter 14.
The circulating water tank 3 is respectively communicated with a first pipeline 11 and a second pipeline 12. The first pipeline 11 is used for receiving the condensate 2, a first connecting pipe is connected to the first pipeline 11, and the other end of the first connecting pipe is communicated with the storage tank 4. The second pipeline 12 is used for introducing the river channel treatment water 1, the second pipeline 12 is connected with a second connecting pipe, and the other end of the second connecting pipe is communicated with the storage tank 4.
The top of the storage tank 4 is provided with a safety valve 9 for preventing overpressure and protecting the safety of the storage tank 4 during use.
The lower part of the storage tank 4 is communicated with a third pipeline 13, and the other end of the third pipeline 13 is communicated with a confluence flow divider 5. A magnetic turning plate liquid level meter 6 is installed in the confluence flow divider 5, and the output end of the magnetic turning plate liquid level meter 6 is connected with a PLC (programmable logic controller); the converging flow divider 5 is also provided with a binding type remote transmission liquid level meter 6, and the output end of the binding type remote transmission liquid level meter 6 is connected with a fog gun pump 8. When the liquid level is detected to be 300mm, the output signal of the binding liquid level meter 6 is disconnected, and the motor control loop of the fog gun pump 8 is disconnected, so that the low-liquid-level interlocking pump stop is realized.
The top end of the converging flow divider 5 is communicated with a top end bent pipe 7, and the top end bent pipe 7 is n-shaped and is vertically arranged. The other end of the top end elbow 7 is communicated with the circulating water tank 3 so as to supplement the treated circulating water into the circulating water tank 3.
The top end of the converging splitter 5 may also be fitted with a safety valve 9 to prevent excessive pressure in the converging splitter 5.
The water outlet of the converging flow divider 5 is communicated with a fog gun through a pipeline, a fog gun pump 8 is arranged on the pipeline, and the controlled end of the fog gun pump 8 is connected with the output end of the PLC.
The circulating water tank 3 is communicated with a water return pipe 10, and a water outlet of the water return pipe 10 is communicated with the converging flow divider 5 so as to provide enough water source required by the fog gun when the water level in the converging flow divider 5 is low. The return pipe 10 is provided with a bypass filter for improving water quality.
All be provided with the solenoid valve on each pipeline, and the controlled end of solenoid valve connects the output of PLC controller.
When the utility model is used for replenishing water to the circulating water tank 3, the converted or synthesized condensate 2 received in the methanol workshop enters the storage tank 4 through the first pipeline 11 and the first connecting pipe; river channel treatment water 1 also enters the storage tank 4 through the second pipeline 12 and the second connecting pipe to be mixed with the condensate 2, and then enters the converging flow divider 5 through the third pipeline 13. The water in the converging flow divider 5 is used for providing treated water with good quality for the fog gun through a pipeline at the bottom under the action of a fog gun pump 8. If the confluence flow divider 5 is filled with water, the excessive water overflows out of the top end bent pipe 7 arranged at the top and finally reaches the circulating water tank 3, so that the waste is prevented, and the danger caused by overlarge pressure is effectively prevented.
The liquid level in the confluence flow divider 5 is detected in real time by a magnetic turning plate liquid level meter 6 and a binding type remote transmission liquid level meter 6 which are arranged on the side wall of the confluence flow divider 5. When the water consumption of the fog gun pump 8 is too large or the condensed water is stopped from entering, the liquid level of the confluence flow divider 5 is reduced to 300mm, the output signal of the binding liquid level meter 6 is disconnected, the motor control loop of the fog gun pump 8 is disconnected, and the low-liquid-level interlocking pump stopping is realized. If the fog gun still needs to be operated at the moment, the PLC opens the electromagnetic valve on the water return pipe 10, and water can be supplied into the converging flow divider 5 through the circulating water pool 3.
