Description

Technical fields:

[0001] This utility model relates to the field of high-temperature wastewater calorific value recovery technology, specifically a high-temperature wastewater calorific value recovery device. Background technology:

[0002] Industrial production generates large amounts of high-temperature wastewater, which contains various soluble ions and impurities and cannot be directly utilized. Direct discharge not only results in the loss of significant secondary energy and water resources but also causes thermal pollution to the environment. Currently, the recovery of high-temperature wastewater generally involves using heat exchangers (such as tubular or plate heat exchangers) to recover the heat carried by the wastewater.

[0003] However, high-temperature wastewater from industrial production often contains various soluble ions and impurities. Suspended solids and particulate matter in the wastewater can deposit on the inner wall of the heat exchanger, forming a fouling layer that increases thermal resistance and reduces heat transfer efficiency. Furthermore, metal ions on the heat exchanger's inner wall may combine with carbonate ions in the wastewater to form insoluble salts, exacerbating scaling. Therefore, to solve these problems, we need to design a high-temperature wastewater heat and mass recovery device. Utility model content:

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figures 1-6 This utility model provides a high-temperature wastewater heat and mass recovery device, comprising:

[0026] The box body 101 has feed inlets 102 fixedly connected to both sides. A top plate 103 is provided on the top of the box body 101. A cleaning component 110 and a drive component 120 are provided on the top plate 103. A stirring component 130 is provided inside the box body 101. A recycling component 140 is provided on one side of the box body 101. A filter component 150 is provided on the feed inlet 102.

[0027] Specifically, since the chamber 101 is an insulated chamber, it prevents high-temperature wastewater from dissipating heat through the chamber and affecting subsequent operations. High-temperature wastewater can be added to the chamber 101 simultaneously from both sides via the inlets 102 on both sides. The wastewater entering the chamber 101 is filtered by the filter assembly 150, removing suspended solids, particulate matter, and other impurities to prevent them from affecting subsequent use. When operators add neutralizing agents or descaling agents to the chamber 101 to neutralize ions and other substances in the wastewater, the wastewater is filtered through… The drive component 120 operates, causing the stirring component 130 to rotate. This allows the wastewater in the tank 101 to mix with the neutralizing agent or descaling agent, causing impurities in the wastewater to precipitate and preventing adverse effects on subsequent operations. The recovery component 140 can recover the waste heat from the high-temperature wastewater in the tank 101, thereby reducing costs in industrial production. Furthermore, the cleaning component 110 can clean the inner wall of the tank 101 and discharge the cleaned dirt or impurities along with the remaining wastewater, facilitating subsequent use of the device.

[0028] Please see Figures 1-4The cleaning assembly 110 includes a first motor 110a, a rotating roller 110b, a bottom cleaning plate 110c, and a side cleaning rod 110d. The first motor 110a is fixedly connected to the top plate 103, the rotating roller 110b is fixedly connected to the first motor 110a, the bottom cleaning plate 110c is fixedly connected to the bottom of the rotating roller 110b, and the side cleaning rod 110d is fixedly connected to the bottom cleaning plate 110c. A drain pipe 101a is fixedly connected to the bottom of the housing 101. A control valve 101b is installed on the drain pipe 101a. A feeding pipe 101c is installed on the housing 101. A water outlet pipe 101d is installed on the housing 101. The other end of the filter pipe 140b is movably connected to the water outlet pipe 101d. A third motor 101e is fixedly connected to the bottom of the housing 101. A rotating plate 101f is fixedly connected to the third motor 101e. The rotating plate 101f is rotatably connected to the water outlet pipe 101d.

[0029] Specifically, when wastewater enters the tank 101, a neutralizing agent or descaling agent solution can be added to the tank 101 through the feeding pipe 101c. This solution is then mixed with the wastewater by the stirring component 130, causing the ions in the wastewater to react and precipitate, facilitating subsequent high-temperature wastewater recovery. The third motor 101e rotates the rotating plate 101f, opening the outlet pipe 101d, allowing the wastewater to enter the recovery component 140 for waste heat recovery. Further, after the wastewater has undergone waste heat recovery, the first... When motor 110a operates, it causes the rotating roller 110b to rotate, which in turn drives the bottom cleaning plate 110c and the side cleaning rod 110d to rotate. This allows the bottom cleaning plate 110c and the side cleaning rod 110d to clean the inner wall of the box 101, removing dirt and other contaminants. By opening the control valve 101b, the cleaned dirt and residual wastewater can be discharged from the drain pipe 101a for subsequent use. Furthermore, since the rotating roller 110b is rotatably connected to the rotating ring 120g, the rotation of the rotating roller 110b will not affect the drive assembly 120 and the stirring assembly 130.

[0030] Please see Figures 1-5The drive assembly 120 includes a second motor 120a, a first bevel gear 120b, a second bevel gear 120c, a bearing 120d, a first gear 120e, a limiting plate 120f, and a rotating ring 120g. The second motor 120a is fixedly connected to the first bevel gear 120b, the rotating ring 120g is fixedly connected to the top of the limiting plate 120f, the bearing 120d is fixedly connected to the rotating ring 120g, the second bevel gear 120c is fixedly connected to the bearing 120d, the first bevel gear 120b meshes with the second bevel gear 120c, the first gear 120e is fixedly connected to the bearing 120d, and the rotating roller 110b is rotatably connected to the rotating ring 120g. The stirring assembly 130 includes a stirring rod 130a, a second gear 130b, and a circular tooth groove 130c. A rotating groove 130d is provided on the top plate 103, and a limiting groove 130e is provided on the rotating groove 130d. The circular tooth groove 130c is fixedly connected to the rotating groove 130d. The second gear 130b is fixedly connected to the stirring rod 130a. The second gear 130b meshes with the first gear 120e and the circular tooth groove 130c. A limiting plate 120f is rotatably connected to the limiting groove 130e, and the stirring rod 130a is rotatably connected to the limiting plate 120f.

[0031] Specifically, when a neutralizing agent or descaling agent solution is added to the housing 101 through the feeding pipe 101c, the second motor 120a operates, causing the first bevel gear 120b to rotate. Since the first bevel gear 120b meshes with the second bevel gear 120c, the second bevel gear 120c rotates. Simultaneously, since the second bevel gear 120c is fixed to the bearing 120d, the outer ring of the bearing 120d drives the first gear 120e to rotate. Since the first gear 120e meshes with the second gear 130b, the second gear 130b meshes with the round teeth... When the groove 130c engages, the second gear 130b rotates within the circular tooth groove 130c, causing the stirring rod 130a to rotate around the rotating roller 110b within the housing 101. This allows the stirring rod 130a to stir and mix the high-temperature wastewater and added solution within the housing 101, thereby neutralizing the ions in the high-temperature wastewater. This prevents ionic impurities in the high-temperature wastewater from precipitating in the housing 101 before entering the recovery component 140 and affecting the inner wall of the inner tube 140e in the heat exchanger 140d, which would be detrimental to waste heat recovery.

[0032] Please see Figures 1-3 The recycling assembly 140 includes a water pump 140a, a filter pipe 140b, a recycling tank 140c, a heat exchanger 140d, and an inner pipe 140e. One end of the filter pipe 140b is movably connected to a pipe on one side of the water pump 140a, and the other side of the water pump 140a is fixedly connected to a pipe on one side of the inner pipe 140e. The inner pipe 140e is located in the heat exchanger 140d, and the other side of the inner pipe 140e is fixedly connected to the recycling tank 140c.

[0033] Specifically, when the third motor 101e rotates the rotating plate 101f, the water pump 140a draws water from the housing 101 into the inner pipe 140e through the outlet pipe 101d. Since the heat exchanger 140d has an inlet and an outlet, water can be added to the heat exchanger 140d through the inlet, enabling the recovery component 140 to recover waste heat from the high-temperature wastewater, improving recovery efficiency and reducing costs in industrial production. Because the filter pipe 140b contains activated carbon adsorption blocks and other adsorption materials, the wastewater can be further purified through the filter pipe 140b, preventing... Ions or other precipitated impurities in the wastewater enter the inner tube 140e of the heat exchanger 140d, causing impurities to precipitate in the inner tube 140e and affecting waste heat recovery. Furthermore, when the filter tube 140b becomes clogged, the rotating plate 101f is rotated by the third motor 101e to close the outlet pipe 101d and stop the water pump 140a. The filter tube 140b can then be disassembled, replaced, and cleaned, facilitating the use of the device, improving its practicality, and reducing costs. The wastewater discharged from the inner tube 140e can be collected and treated centrally through the recovery box 140c.

[0034] Please see Figures 1-6 The filter assembly 150 includes a filter screen 150a and a raised strip 150b. A placement groove 150c is provided on the feed inlet 102. A fixing groove 150d is provided in the placement groove 150c. The raised strip 150b is fixedly connected to the filter screen 150a. A pull groove 150e is provided on the inner side of the filter screen 150a.

[0035] Specifically, when adding high-temperature wastewater to the housing 101, the pipe connecting the high-temperature wastewater to the inlet 102 is connected. Under operator control, the high-temperature wastewater enters the housing 101 through the inlet 102. The filter screen 150a on the inlet 102 filters out suspended solids, particulate matter, and other impurities from the wastewater, preventing them from affecting the subsequent operation of the heat exchanger. The multiple inlets 102 and filter components 150 on the housing 101 improve the efficiency of wastewater heat recovery. Furthermore, if impurities accumulated in the filter component 150 of one inlet 102 affect the entry of wastewater into the housing 101, the operator... High-temperature wastewater is stopped from entering the housing 101 from the feed inlet 102 on this side. The operator pulls the pull groove 150e to move the protrusion 150b on the filter screen 150a out of the fixing groove 150d, so that the filter screen 150a can be replaced and disassembled. Furthermore, when the filter screen 150a is installed on the feed inlet 102, the feed inlet 102 is provided with a placement groove 150c, so that the filter screen 150a can be placed in the placement groove 150c and fixed to the fixing groove 150d by the protrusion 150b. This can fix the filter screen 150a on the feed inlet 102 and prevent the filter screen 150a from falling off and affecting the filtration of impurities in the wastewater.

[0036] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
