Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater technology, and in particular to a waste heat recovery device for preventing scaling in industrial wastewater. Background Technology

[0002] Industrial wastewater, including production wastewater, industrial sewage, and cooling water, refers to the wastewater and waste liquid generated during industrial production processes. It contains industrial raw materials, intermediate products, by-products, and pollutants lost during production. Industrial wastewater is diverse and complex in composition. For example, wastewater from the electrolytic salt industry contains mercury; wastewater from the heavy metal smelting industry contains lead, cadmium, and other metals; wastewater from the electroplating industry contains cyanide and chromium, among other heavy metals; wastewater from the petroleum refining industry contains phenols; and wastewater from the pesticide manufacturing industry contains various pesticides. Because industrial wastewater often contains multiple toxic substances, it pollutes the environment and poses a significant threat to human health. Therefore, it is essential to develop comprehensive utilization methods to turn harm into benefit, and to implement appropriate purification measures based on the composition and concentration of pollutants in the wastewater before discharge.

[0003] During the discharge and circulation of industrial wastewater, a large amount of heat is generated. Due to the nature of the wastewater, it cannot be utilized extensively. However, the thermal energy of industrial wastewater can be reused to avoid the waste of heat energy caused by cooling the wastewater after discharge. Utilizing its thermal energy for high-level water source heat exchange is the best and most worry-free method. Furthermore, through different connection methods, heat exchange can maximize the utilization of thermal energy.

[0004] Chinese patent document CN213984746U discloses an industrial wastewater waste heat recovery device, comprising a cuboid with a first groove inside. A fixed rod is fixedly connected inside the first groove, and a pressing rod is slidably connected to one end of the fixed rod. The end of the pressing rod away from the fixed rod passes through the outer wall of the cuboid and is slidably connected to the cuboid. A connecting block is fixedly connected to the outer wall of the pressing rod, and a spring is provided between the connecting block and the first groove. The aforementioned patent document increases the stability of the pressing rod by setting a fixed rod inside the first groove, allows the pressing rod to return to its original position by adding a spring, restricts the movement trajectory of the first slider by adding a first groove (the width of the first groove is smaller than the width of the second groove, and the lengths of the first and second grooves are equal), and prevents the second slider from sliding out of the second groove. The addition of a support plate allows the sliding sleeve to swing.

[0005] The aforementioned patent documents make it convenient, simple, time-saving, and labor-saving to replace the internal heat exchange tube during implementation. However, they cannot prevent dirt from adhering to the tube wall during use. Thick dirt hinders the thermal conductivity of the heat exchange tube and affects the waste heat recovery efficiency. Utility Model Content

[0006] The main purpose of this utility model is to provide an anti-scaling industrial wastewater waste heat recovery device, which can effectively solve the problem of not being able to prevent scale from adhering to the pipe wall during use.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A waste heat recovery device for anti-scaling industrial wastewater includes a tank. A supporting mechanism is fixedly connected to the lower end of the outer surface of the tank. A servo motor is fixedly installed in the middle of the supporting mechanism. A stirring mechanism is fixedly connected to the upper output end of the servo motor. A heat conduction mechanism is fixedly installed in the middle of the inner cavity of the tank. A flushing mechanism is fixedly connected to the upper end of the outer surface of the tank. A water injection component is fixedly connected to the middle of the upper end of the outer surface of the tank. A drainage component is fixedly connected to the lower right side of the outer surface of the tank.

[0009] Preferably, the bearing mechanism includes a chassis, and a plurality of support columns are fixedly connected in a ring array on the outer side of the upper end of the chassis, and a bearing frame is fixedly connected to the upper end of the plurality of support columns.

[0010] Preferably, the stirring mechanism includes a rotating shaft, with auger blades fixedly connected to the outer surface of the rotating shaft, and the lower end of the rotating shaft is fixedly connected to the upper output end of the servo motor.

[0011] Preferably, the water injection assembly includes a water injection pipe, and a solenoid valve is fixedly installed in the middle of the inner cavity of the water injection pipe.

[0012] Preferably, the drainage assembly includes a drain pipe, and a second solenoid valve is fixedly installed at the top of the inner cavity of the drain pipe.

[0013] Preferably, the heat conduction mechanism includes a heat exchange tube, with a hot fluid pipe fixedly connected to the upper rear input end of the heat exchange tube and a cold fluid pipe fixedly connected to the upper front output end of the heat exchange tube.

[0014] Preferably, the flushing mechanism includes an annular water supply pipe, and a plurality of diversion pipes are fixedly connected in an annular array to the lower part of the outer surface of the annular water supply pipe, and a high-pressure nozzle is fixedly connected to the lower end of the outer surface of each of the diversion pipes.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model achieves stable support for the tank through the bearing mechanism, agitation mechanism for stirring industrial wastewater, heat conduction mechanism for conducting and recovering heat from the industrial wastewater injected into the tank cavity, thus improving the practicality of the device. The flushing mechanism facilitates the cleaning of dirt adhering to the heat conduction mechanism. The water injection component facilitates the addition of industrial wastewater, and the drainage component facilitates the discharge of industrial wastewater, thus improving the practicality and versatility of the device.

[0017] 2. This utility model uses a servo motor to drive the rotating shaft and auger blades to rotate, thereby continuously conveying the high-temperature industrial wastewater and sediment in the inner cavity of the tank upwards. During this process, the rotating auger blades can stir the wastewater, making the water temperature more uniform at different levels. This allows the heat exchange tube cavity to absorb heat more fully and efficiently. At the same time, the sediment being continuously conveyed upwards by the auger blades can prevent particulate matter from adhering to the outer wall of the heat exchange tube for a long time, thus avoiding the phenomenon that particulate matter is difficult to clean due to prolonged adhesion to the outer wall of the heat exchange tube. This improves the practicality and versatility of the device. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 As shown, an anti-scaling industrial wastewater waste heat recovery device includes a tank 1. A bearing mechanism 2 is fixedly connected to the lower end of the outer surface of the tank 1 to provide stable support for the tank 1. A servo motor 3 is fixedly installed in the middle of the bearing mechanism 2. A stirring mechanism 4 is fixedly connected to the upper output end of the servo motor 3 to stir the industrial wastewater. A heat conduction mechanism 5 is fixedly installed in the middle of the inner cavity of the tank 1 to conduct and recover heat from the industrial wastewater injected into the inner cavity of the tank 1. A flushing mechanism 6 is fixedly connected to the upper end of the outer surface of the tank 1 to facilitate the cleaning of dirt attached to the heat conduction mechanism 5. A water injection component 7 is fixedly connected to the middle of the upper end of the outer surface of the tank 1 to facilitate the addition of industrial wastewater. A drainage component 8 is fixedly connected to the lower right end of the outer surface of the tank 1 to facilitate the discharge of industrial wastewater.

[0025] To achieve stable load-bearing for tank 1, refer to Figure 2 The supporting mechanism 2 includes a chassis 21. Several support columns 22 are fixedly connected to the outer ring of the upper end of the chassis 21. The upper ends of the several support columns 22 are fixedly connected to a supporting frame 23, which can realize the function of supporting the tank 1 and the servo motor 3.

[0026] To achieve the purpose of stirring industrial wastewater, see [reference needed]. Figure 3 The stirring mechanism 4 includes a rotating shaft 41, and an auger blade 42 is fixedly connected to the outer surface of the rotating shaft 41. It can continuously transport the particles settled at the bottom upward while stirring the wastewater. The lower end of the rotating shaft 41 is fixedly connected to the upper output end of the servo motor 3.

[0027] For ease of industrial wastewater disposal, please refer to... Figure 3 The water injection component 7 includes a water injection pipe 71, and a solenoid valve 72 is installed and fixed in the middle of the inner cavity of the water injection pipe 71.

[0028] When it is necessary to inject industrial wastewater into the inner cavity of tank 1, open solenoid valve 72, connect the upper opening end of water injection pipe 71 to the external sewage pipe, and then inject an appropriate amount of industrial wastewater into the inner cavity of tank 1.

[0029] For the purpose of facilitating the discharge of industrial wastewater, please refer to Figure 3 The drainage assembly 8 includes a drain pipe 81, and a solenoid valve 82 is fixedly installed on the top of the inner cavity of the drain pipe 81.

[0030] When it is necessary to discharge industrial wastewater from the inner cavity of tank 1, solenoid valve 282 is opened, allowing the industrial wastewater from the inner cavity of tank 1 to be gradually discharged to the outside.

[0031] To achieve the purpose of heat conduction and recovery of the industrial wastewater injected into the inner cavity of tank 1, refer to... Figure 4 The heat conduction mechanism 5 includes a heat exchange tube 51, with a hot fluid pipe 52 fixedly connected to the upper rear input end of the heat exchange tube 51 and a cold fluid pipe 53 fixedly connected to the upper front output end of the heat exchange tube 51.

[0032] After cold water is injected into the inner cavity of the heat exchange tube 51 through the hot fluid connector 52, the heat generated by the industrial wastewater in the inner cavity of the tank 1 will be fully absorbed through the tube wall of the heat exchange tube 51. At this time, after the cold water in the inner cavity of the heat exchange tube 51 absorbs heat and heats up, it will be discharged to the outside through the cold fluid connector 53 for recycling.

[0033] To facilitate the cleaning of dirt adhering to the heat conduction mechanism 5, please refer to... Figure 4 The rinsing mechanism 6 includes an annular water supply pipe 61. Several branch pipes 62 are fixedly connected to the lower part of the outer surface of the annular water supply pipe 61 in an annular array. High-pressure nozzles 63 are fixedly connected to the lower end of the outer surface of each branch pipe 62.

[0034] After the wastewater inside the tank 1 is discharged to the outside for unified collection and treatment, the left input end of the annular water pipe 61 can be connected to the output end of the external clean water pump. Then, clean water is injected into the inner cavity of the annular water pipe 61. At this time, the clean water will be diverted into the inner cavities of several diversion pipes 62, and finally sprayed downwards under the action of several corresponding high-pressure nozzles 63, so as to clean the dirt attached to the outer wall of the heat exchange tube 51 in a timely manner.

[0035] It should be noted that the servo motor 3 in this utility model is a Siemens 1FT7, the heat exchange tube 51 is a WH-200 type, and the solenoid valve 72 and solenoid valve 82 are DSG-02. The specific installation method, circuit connection method and control method of the servo motor 3, heat exchange tube 51, solenoid valve 72 and solenoid valve 82 are all conventional designs, and this utility model will not describe them in detail.

[0036] The working principle of this utility model is as follows: First, a certain amount of industrial wastewater is injected into the inner cavity of the tank 1 through the water injection pipe 71. Then, cold fluid is injected into the inner cavity of the cold fluid connector 53, causing the cold fluid to flow along the inner cavity of the heat exchange pipe 51. During this process, the high-temperature industrial wastewater injected into the inner cavity of the tank 1 will conduct the high temperature to the cold fluid in the inner cavity of the heat exchange pipe 51, thereby heating the cold fluid. Then, it is discharged to the outside through the hot fluid connector 52 for recycling. At the same time, the power of the servo motor 3 is turned on, causing it to drive the rotating shaft 41 and the auger blades 42 to rotate, thereby raising the industrial wastewater and sediment deposited at the bottom of the inner cavity of the tank 1 upward. The conveying system ensures that the industrial wastewater and particulate matter inside the tank 1 are evenly distributed within the tank 1. When the industrial wastewater inside the tank 1 needs to be discharged or replaced, the solenoid valve 82 is opened, allowing the wastewater inside the tank 1 to be discharged along the drain pipe 81 to the outside for collection and treatment. At this time, the input end of the left side of the annular water conveying pipe 61 can be connected to an external water pump, and then the power supply of the water pump is turned on, allowing clean water to flow along the annular water conveying pipe 61 into the inner chambers of several branch pipes 62, and then sprayed downwards through the corresponding high-pressure nozzles 63, thereby promptly flushing away the particulate matter attached to the outer wall of the heat exchange tube 51.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
