Description

Technical Field

[0001] This utility model relates to the field of heat exchanger wastewater treatment technology, specifically a pretreatment device for hot wastewater from heat exchanger units. Background Technology

[0002] Many industrial processes, such as textiles, printing and dyeing, chemicals, and pharmaceuticals, generate large amounts of hot wastewater. This wastewater typically has a high temperature and contains various pollutants, such as organic matter, colloids, impurities, acids, and alkalis. Direct discharge of such wastewater not only wastes water resources but also pollutes the environment.

[0003] Chinese patent CN216409908U provides a pretreatment device for hot wastewater in a heat exchanger unit, including a mounting frame, a sliding groove, and a handle. The sliding groove specifically comprises a slider, a lifting transmission block, teeth, a through groove, a round button, a disc, a connecting rod, a hollow tube, a generator, a pipe, a drive shaft, a turbine, a sealing plug, a rotating shaft, and a rotating plate. The sliding groove is mounted on the mounting frame, and a slider is slidably connected within it. A lifting transmission block is located on one side of the slider, and a through groove is formed on the lifting transmission block. Teeth are formed on the inner surface of the through groove. A three-phase asynchronous motor is mounted on the mounting frame, and the power output end of the three-phase asynchronous motor is connected to the power input end of the disc. By adjusting the pressure difference of the water flow, the flow rate of the water can be accelerated, thereby increasing the turbine speed and improving power generation efficiency. This enables self-sufficiency in electricity and saves resources.

[0004] When the heat exchanger unit uses the above-mentioned heat-containing wastewater pretreatment device, the high temperature during the pretreatment process causes scale to precipitate inside the wastewater, which reduces the treatment efficiency of the heat-containing wastewater and may cause blockage over time.

[0005] Therefore, this utility model provides a pretreatment device for hot wastewater in heat exchange units to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a pretreatment device for hot wastewater in heat exchange units. This device solves the problem that, during the pretreatment process of hot wastewater in heat exchange units, the high temperature causes scale to precipitate inside the wastewater, resulting in reduced treatment efficiency and potential blockage over time.

[0014] Beneficial effects

[0015] This invention provides a pretreatment device for hot wastewater in heat exchanger units. Compared with the prior art, it has the following advantages:

[0016] (1) A heat exchanger unit heat-containing wastewater pretreatment device, by setting up a descaling component, can control the amount of scale inhibitor added according to the actual flow rate of the wastewater, thereby preventing the formation of scale inside the pipe after long-term use, and achieving the effect of preventing scale formation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figure 1-3 A heat exchanger unit heat wastewater pretreatment device includes a base 1, a wastewater tank 4 fixed on the top left side of the base 1, an adding component 2 sealed to the right side of the wastewater tank 4, a heat exchange filter box 5 sealed to the other side of the adding component 2, and a detection component 3 fixed to the other end of the heat exchange filter box 5.

[0026] The addition component 2 includes an addition box 21, an impeller 22 is rotatably connected inside the addition box 21, gears 23 are fixed on both sides of the impeller 22, a rack 24 is meshed with the side of the gears 23, a connecting block 25 is fixed on the side of the rack 24, an addition tube 26 is sealed to the top of the addition box 21, a storage box 27 is fixed to the top of the addition tube 26, an adjusting ring 28 is rotatably connected to the inner wall of the addition tube 26, and the other end of the connecting block 25 is fixed to the adjusting ring 28. The adjusting ring 28 is made of elastic material and is malleable.

[0027] A sealing plate 29 is slidably connected inside the adding tube 26. A groove is opened inside the adding tube 26, and the sealing plate 29 is slidably connected in the groove. The sealing plate 29 keeps the inside of the adding tube 26 sealed when the connecting block 25 moves.

[0028] Support columns 210 are fixed on both sides of the adding box 21. Positioning columns 211 are fixed inside the support columns 210. A collar 212 is slidably connected to the positioning column 211. The other end of the collar 212 is fixed to the rack 24. The positioning column 211 provides a limit for the rack 24 to prevent the rack 24 from shifting to both sides.

[0029] A spring 213 is fixed at the bottom of the rack 24. The spring 213 can cause the rack 24 to automatically spring back to its original position when the impeller 22 is not driven to rotate by the wastewater flow.

[0030] In this embodiment, when wastewater from the base 1 enters the addition tank 21, the wastewater flow rate is relatively fast, causing the impeller 22 to rotate. This causes the impeller 22 to drive the gear 23 to rotate and mesh with the rack 24. This causes the rack 24 to lift the collar 212 and slide downward in the positioning post 211. The connecting block 25 on the side of the rack 24 drives the adjusting ring 28 to adjust, thereby widening the opening of the adjusting ring 28. When the opening of the adjusting ring 28 widens or narrows, the sealing plate 29 inside the addition tube 26 can keep the inside of the addition tube 26 sealed. At this time, the storage tank 27 can add scale inhibitor to the addition tank 21 according to the wastewater flow rate. When the wastewater flow rate decreases or remains stationary, the rack 24 rebounds upward by the elastic force of the spring 213, causing the rack 24 to drive the gear 23 and the impeller 22 to rotate in opposite directions. The force of the impeller 22 rotation cancels out the force applied by the wastewater flow rate, thereby keeping the opening size of the adjusting ring 28 unchanged.

[0031] Example 2:

[0032] Please see Figure 1-4Based on Embodiment 1, this embodiment provides a technical solution. The detection component 3 includes a temperature detector 31. The temperature detector 31 is installed on the output pipe of the heat exchange filter box 5. An adjustment column 32 is fixed on the side of the temperature detector 31 away from the heat exchange filter box 5. A motor 33 is fixed on the top of the adjustment column 32. A rotating column 34 is fixed on the output end of the motor 33. A baffle 35 is fixed on the side of the rotating column 34.

[0033] The heat exchange filter box 5 is externally sealed with a return pipe 36. An adjusting column 32 is installed at the connection between the return pipe 36 and the heat exchange filter box 5. The return pipe 36 can transport substandard wastewater back to the inlet of the heat exchange filter box 5.

[0034] In this embodiment, after the wastewater undergoes heat exchange filtration in the heat exchange filter box 5, it passes through the temperature detector 31. The temperature detector 31 detects the temperature of the wastewater. If the temperature does not meet the standard, the temperature detector 31 controls the motor 33, causing the motor 33 to drive the rotating column 34 to rotate. This causes the baffle 35 on the side of the rotating column 34 to rotate to the side away from the return pipe 36, allowing the wastewater to flow through the return pipe 36 to the inlet of the heat exchange filter box 5, thus achieving the effect of secondary heat exchange filtration of the wastewater. When the wastewater meets the standard, the baffle 35 rotates to the side closer to the return pipe 36, allowing the wastewater to flow to the next processing step.
