Description

Technical Field

[0001] The present application relates to the technical field of boilers, and in particular to a boiler with water quality detection function. Background Art

[0002] In the prior art, when the boiler is working, the boiler water quality affects the operation safety of the entire boiler. When the boiler water is mixed with calcium and magnesium salts, it is easy to scale at high temperature in the boiler, which will cause uneven local temperature in the boiler, waste heat energy, corrosion under the scale, and the consequences will cause bulging or even bursting accidents of the boiler tube. Therefore, the boiler water must be monitored. Many existing boiler water monitoring methods use manual sampling, which is time-consuming and laborious. Some use direct immersion into the water quality transmitter for installation. After long-term use, a layer of scale will also form on the surface of the water quality transmitter, resulting in a large error between the monitoring data and the actual situation.

[0021] To facilitate understanding of the boiler with water quality detection provided in the embodiment of the present application, its application scenario is first described. The boiler with water quality detection provided in the embodiment of the present application is used to produce steam. However, current boilers are prone to scale in the boiler when producing steam, which affects the heating effect of the boiler. For this reason, the embodiment of the present application provides a boiler with water quality detection to improve the detection effect of water quality. It is described in detail below in conjunction with specific drawings and embodiments.

[0022] refer to Figure 1 , Figure 1 The schematic diagram of the structure of the boiler with water quality detection provided by the embodiment of the present application is shown in FIG. The main structure of the boiler with water quality detection includes a boiler body 10, and the boiler body 10 is used to heat water to generate water vapor. In addition, the boiler also includes a water quality detection device 30. The water quality detection device 30 is used to detect the water quality of the water entering the boiler. Figure 1 The specific structure of the boiler with water quality detection is explained in detail.

[0023] Continue to refer Figure 1 The boiler body 10 is connected to a water inlet pipe 20. When the boiler is working, water is injected into the boiler body 10 through the water inlet pipe 20, and the boiler body 10 generates steam by heating the water.

[0024] When the water quality detection device 30 is provided, a detection connection port is provided on the water inlet pipe 20. The water quality detection device 30 is connected to the water inlet pipe 20 through the detection connection port. When the water inlet pipe 20 supplies water to the boiler body 10, the water can be supplied to the water quality detection device 30 at the same time, so that the water quality can be detected by the water quality detection device 30.

[0025] Continue to refer Figure 1As shown in the figure, the water quality detection device 30 includes a housing chamber 31, a detection device 32 disposed in the housing chamber 31, a water inlet pipe 34 connecting the housing chamber 31 and the detection connection port, and a water outlet pipe 33 connecting the boiler body 10 and the housing chamber 31; wherein the water inlet pipe 34 is provided with a first control valve 36, and the water outlet pipe 33 is provided with a second control valve 35. Specifically, the housing chamber 31 is used to accommodate water supplied by the water inlet pipe 20, and the detection device 32 is used to detect water quality. Among them, the detection device 32 can be a conventional electronic device for detecting water quality, which is not specifically illustrated here.

[0026] When the water quality detection device 30 is connected to the water inlet pipe 20, the water inlet pipe 34 is connected to the water inlet pipe 20. Specifically, the water inlet pipe 34 includes a first sub-water inlet pipe and a second sub-water inlet pipe threadedly connected to the first sub-water inlet pipe; wherein the first sub-water inlet pipe is threadedly connected to the water inlet pipe 20; the second sub-water inlet pipe is threadedly connected to the accommodating chamber 31; and the first control valve 36 is arranged on the first sub-water inlet pipe. When it is necessary to detect the water quality, water can be allowed to enter the accommodating chamber 31 by opening the first control valve 36. When it is not necessary to detect the water quality, the first control valve 36 can be closed. In the embodiment of the present application, the first control valve 36 can be different types of valves. Exemplarily, the first control valve 36 includes a switch valve and a one-way valve connected in series with the switch valve. Of course, in addition to the valves in the above examples, other valves can also be used, such as different types of valves such as solenoid valves or regulating valves.

[0028] When both the water inlet pipe 34 and the water outlet pipe 33 are made of two sections, when the water quality detection device 30 needs to be replaced, the first control valve 36 and the second control valve 35 can be directly closed, and then the second sub-outlet pipe and the second water inlet pipe 34 can be removed and replaced as a whole.

[0029] When performing water quality testing, the water quality testing device 30 is also very likely to cause errors in the detection due to the deposition of scale. For this reason, the boiler of the device to be tested provided in the embodiment of the present application also includes a water supply device 50, which is connected to the water inlet pipe 34 through an external flushing pipe, and the external flushing pipe is provided with a third control valve.

[0030] In addition, the boiler with water quality detection further includes an emptying device 40, wherein the emptying device 40 is connected to the accommodating chamber 31 and is used to empty the liquid in the accommodating chamber 31; the liquid may be a detection liquid flowing from the water inlet pipe 20 into the accommodating chamber 31, or a cleaning liquid flowing from the water supply device 50 into the accommodating chamber 31. Exemplarily, the accommodating chamber 31 is located above the water inlet pipe 20; the emptying device 40 may be an air inlet valve disposed in the accommodating chamber 31. In addition, the accommodating chamber 31 is located below the water inlet pipe 20; the emptying device 40 may be an air pump connected to the accommodating chamber 31. That is, the emptying device 40 may select different structures according to the placement position of the accommodating chamber 31.

[0031] In an optional solution, the boiler with water quality detection provided in the embodiment of the present application also includes a control device, which is used to receive the detection result of the water quality detection device 30, and when the detection result exceeds the first set value, an alarm is issued; when the detection result exceeds the second set value, the boiler body 10 is controlled to stop working. The control device is a common control device such as a single-chip microcomputer or a PLC, an industrial computer, etc. It compares the detection data with the set data, and controls different devices to work according to the comparison result, which is a conventional control logic in the field, so it will not be described in detail.

[0032] In the above technical solution, the water entering the boiler is tested by connecting the water quality detection device 30 to the water inlet pipe 20. The water quality detection device 30 is cleaned by the water supply device 50, thereby improving the reliability of the water quality detection device 30 during detection, and further improving the detection effect of the water entering the boiler.
