It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0028] Example High-safety boiler condensate circulation system

[0030] The steam outlet of the water tube boiler 1 is connected to the steam inlet of the first tubular heat exchanger 3 through the first pipe, the condensate outlet of the first tubular heat exchanger 3 is connected to the water inlet of the water tank 2 through the second pipe, and the water outlet of the water tank 2 is connected to the water inlet of the water tube boiler 1 through the third pipe. One end of the spare pipe is connected to the steam outlet of the water tube boiler 1, and the other end is connected to the water inlet of the water tank 2. A first solenoid valve 71 is provided on the first pipe, and a second solenoid valve 72 is provided on the second pipe. A sewage pipe is externally connected to the second pipe between the condensate outlet of the first tubular heat exchanger 3 and the second solenoid valve 72, and a third solenoid valve 73 is provided on the sewage pipe; a fourth solenoid valve 74 is provided on the spare pipe. The signal output end of the pH analyzer 4 is connected to the water quality signal input end of the control device, and the control signal output end of the control device is respectively connected to the first solenoid valve 71, the second solenoid valve 72, the third solenoid valve 73, the fourth solenoid valve 74 and the alarm device.
[0031] In order to facilitate the unified treatment of sewage, this embodiment further provides a sewage pool 5 at the sewage outlet of the sewage pipe.
[0032] In order to effectively utilize the steam heat during the maintenance of the first tubular heat exchanger 3, the utility model is further optimized as follows: the standby pipeline includes a first standby pipeline and a second standby pipeline, the first standby pipeline is connected to the steam outlet of the water tube boiler 1, the second standby pipeline is connected to the water inlet of the water tank 2, and a second tubular heat exchanger 6 and a cooling device for heat exchange with the second tubular heat exchanger 6 are arranged between the first standby pipeline and the second standby pipeline. At the same time, the fourth solenoid valve 74 is arranged on the first standby pipeline.
[0033] In order to further improve the safety and reliability of the entire system, the present embodiment sets an alarm device in the duty room. The alarm device adopts a commercially available alarm device with sound and light alarm functions.
[0034] In this embodiment, the pH analyzer 4 includes a composite electrode, a sensor and a secondary meter. The composite electrode is connected to the secondary meter through the sensor, and the signal output end of the secondary meter is connected to the water quality signal input end of the control device. In order to ensure the accuracy and comprehensiveness of the water quality test results, the composite electrode is set at the water outlet of the first tubular heat exchanger 3 in this embodiment. Among them, the pH analyzer 4 can be a commercially available product, which has its own alarm function. When the water quality test result exceeds the internal threshold, it automatically alarms.

[0035] Working principle of this embodiment: Under normal conditions, the first solenoid valve 71 and the second solenoid valve 72 are open, the third solenoid valve 73 and the fourth solenoid valve 74 are closed, the steam generated by the water tube boiler 1 enters the first tubular heat exchanger 3 through the first pipeline for heat exchange, the first tubular heat exchanger 3 heats various cleaning liquids through steam, and the generated condensed water enters the water tank 2 through the second pipeline, and finally returns to the water tube boiler 1 through the third pipeline. The pH analyzer 4 detects the water quality of the first tubular heat exchanger 3 in real time and feeds back to the control device. When the detection result exceeds the internal threshold, the pH analyzer 4 automatically alarms, and the control device sends a control signal to close the first solenoid valve 71 and the second solenoid valve 72, and open the third solenoid valve 73 and the fourth solenoid valve 74, thereby enabling the second tubular heat exchanger 6 and the sewage pipeline. At the same time, the control device also sends a control signal to make the alarm device sound an alarm to notify the duty personnel. The contaminated water is discharged into the sewage pool through the sewage pipe. After the first tubular heat exchanger 3 is replaced or repaired, the first solenoid valve 71 can be opened first until the water quality test result returns to normal for a certain period of time, and then the third solenoid valve 73 and the fourth solenoid valve 74 are closed, and the second solenoid valve 72 is opened to re-activate the first tubular heat exchanger 3.
