Description

Technical Field

[0001] The present invention relates to the technical field of water quality monitoring, and in particular to an online monitoring device for boiler water quality. Background Art

[0002] A boiler can heat the water passed into it to produce hot water or steam. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and life, or can be converted into mechanical energy through a steam power device. The boiler that provides hot water is called a hot water boiler, which is mainly used in life. When the boiler is in use, in order to ensure the water quality of the hot water, a water quality monitoring device is sometimes installed on the boiler to monitor changes in the boiler water quality. When the existing boiler water quality online monitoring device is in use, since the hot water temperature is high and the operating temperature of some water quality monitors is low, a water quality monitor is installed at the boiler water inlet pipe. In this way, if there are certain impurities in the boiler after long-term use, and the impurities pollute the hot water to a certain extent, it is difficult to quickly monitor changes in water quality, which is inconvenient to use.

The water in the conveying trough can flow into the sampling box through the opening on the cover.

[0010] Furthermore, the inner side surface of the regulating box is fixedly connected to a support plate fixedly connected to one side surface of the plurality of U-shaped tubes, and the support plate can limit the position of the U-shaped tubes.

The hot water can enter the interior of the spiral frame through several adjacent connecting frames at the top, or directly enter the interior of the spiral frame from the bottom of the spiral frame. After passing through the interior of the spiral frame, the hot water will enter an annular plate and then enter the connecting pipe, thereby being transported into the cooling module. After the water quality test is completed, the water can enter a delivery frame from the connecting pipe 2, and then enter the outside of the spiral frame through the adjacent connecting frame. After passing through the spiral frame, the water can enter the connection frame of another annular plate, and then enter another delivery frame, and then can re-enter the water outlet pipe of the boiler through the delivery pipe 2. When the tested water flows outside the spiral frame, it can exchange heat with the untested hot water in the spiral frame, thereby preliminarily heating the tested water and preliminarily cooling the untested water, which is beneficial to saving energy, and the water thickness inside and outside the spiral frame is thin, which is convenient for sufficient heat exchange.

[0013] The top of the inner side of the other annular plate is provided with a communicating frame, the side surface of the communicating frame is connected with one end of the conveying pipe, the side surface and the bottom surface of the communicating frame are provided with a plurality of communicating grooves, the bottom surface and the side surface of the communicating frame are provided with a limiting frame, the inner side surface of the limiting frame is fixedly connected with a plurality of plug-in rods plugged into adjacent communicating grooves, the bottom surface and the side surface of the communicating frame are fixedly connected with a plurality of fixed blocks, the inner side surface of the fixed block is slidably connected with a sliding block fixedly connected to the adjacent limit frame, the inner side surface of the sliding block is fixedly connected with a spring fixedly connected to the inner side surface of the fixed block, under the action of the spring, the plug-in rod can block the communicating groove, and the hot water in the conveying pipe can be conveyed to the communicating frame in the other annular plate, and the hot water in the communicating frame can squeeze the plug-in rod.

[0014] Furthermore, a heater is provided on the side of the second delivery pipe, and the water in the second delivery pipe can be heated by the heater and then re-sent into the water outlet pipe of the boiler, thereby avoiding re-adding the cooled water into the water outlet pipe of the boiler, which affects the temperature of the hot water.

[0015] Beneficial effects of the present invention:

[0016] 1. A rotating pipe is fixedly connected to the inner side of the regulating box, which connects the boiler water outlet pipe with the connecting module, so that the connecting module can transport hot water to the inside of branch pipe 2 through the connecting pipe. The hot water can flow from branch pipe 2 to the adjacent U-shaped pipe 2, and then from U-shaped pipe 2 to the adjacent U-shaped pipe 1, so that the hot water alternately flows in U-shaped pipe 2 and U-shaped pipe 1, and finally flows into branch pipe 1 through U-shaped pipe 1, and then flows into the monitoring module from branch pipe 1 for water quality monitoring. When the hot water circulates in U-shaped pipe 2, the hot water can be cooled by the coolant, thereby reducing the hot water temperature, so that the monitoring module can smoothly perform water quality detection on the water at the boiler water outlet pipe.

[0017] 2. Through the meshing transmission of the gear ring and the adjusting gear, the adjusting motor can be used to drive the adjusting rod to rotate, and the adjusting rod can rotate the adjusting box through the adjusting gear and the gear ring, thereby adjusting the relative position of the U-shaped tube 1 and the U-shaped tube 2, adjusting the U-shaped tube 1 corresponding to the branch pipe 1, and adjusting the U-shaped tube 2 corresponding to the branch pipe 2. In this way, the number of U-shaped tubes 1 and 2 between the branch pipe 1 and the branch pipe 2 can be changed, thereby changing the number of U-shaped tubes 1 and 2 through which the hot water flows, and changing the length of the hot water flowing in the connecting box. In this way, when the hot water with a relatively low temperature flows through the connecting box for cooling, a long flow distance is avoided, which causes the water temperature to drop too low. In this way, the degree of cooling can be adjusted according to the hot water temperature, which is more flexible to use. Moreover, when the hot water is subsequently reheated, the water temperature is avoided from being too low, resulting in a need for more time and energy for heating.

[0018] 3. Several connecting frames are fixedly connected through a spiral frame. The hot water drawn into the delivery pipe 1 can flow from the delivery frame and the connecting frame through the inside of the spiral frame, and then flow into the connecting pipe. The water after cooling and testing can flow from the connecting pipe 2 into a delivery frame, and then flow from the connecting frame into the outside of the spiral frame, and finally flow into another delivery frame and the delivery pipe 2. In this way, the water after testing and the water before monitoring can undergo a more sufficient heat exchange, the water after testing can be heated, and the water before testing can be cooled, which is beneficial to saving energy.

After passing through the spiral frame 311, the water can enter the connecting frame 331 of another annular plate 320, and then enter another conveying frame 330. When the tested water flows outside the spiral frame 311, it can exchange heat with the untested hot water in the spiral frame 311, thereby preliminarily heating the tested water and preliminarily cooling the untested water. The tested water can enter the second conveying pipe 500 from the other conveying frame 330. The water in the second conveying pipe 500 can be heated by the heater 700 and then sent back to the water outlet pipe of the boiler.

[0049] During detection, if the water temperature is relatively low, the regulating motor 222 can drive the regulating rod 225 to rotate, the regulating rod 225 can drive the regulating gear 226 to rotate, the regulating gear 226 can rotate the gear ring 223, the gear ring 223 can drive the regulating box 221 to rotate, and the regulating box 221 can drive the U-shaped tube 2 260 to rotate through the adjacent connecting plate 240, thereby adjusting the relative positions of the U-shaped tube 1 250 and the U-shaped tube 2 260, and correspondingly matching the corresponding U-shaped tube 1 250 with the branch pipe 1 231, and correspondingly matching the corresponding U-shaped tube 2 260 with the branch pipe 2 270. In this way, the number of U-shaped tubes 1 250 and U-shaped tubes 2 260 that water passes through when flowing between the branch pipe 1 231 and the branch pipe 2 270 can be changed, and the length of the hot water flowing in the connecting box 211 can be changed, thereby adjusting the degree of cooling according to the temperature of the hot water.
