Description

Technical Field

[0001] This utility model belongs to the field of condensate recovery technology, specifically relating to a closed-loop condensate recovery and flash evaporation utilization system. Background Technology

[0002] Steam, as a heat energy carrier, is widely used in industries such as power generation, petroleum, chemical, printing and dyeing, papermaking, textiles, brewing, rubber, and ceramics. After releasing its latent heat of vaporization in various steam-using equipment, steam transforms into saturated condensate at nearly the same temperature and pressure. Because the operating pressure of steam is greater than atmospheric pressure, the heat contained in the condensate can reach 20%-30% of the total heat of the steam. Furthermore, the higher the pressure and temperature, the more heat the condensate contains, and the larger its proportion of the total steam heat. It can be seen that 100% recovery and effective utilization of the heat from the condensate has significant energy-saving potential.

[0004] However, current closed-loop condensate recovery devices have the following problems: they cannot allow the stirred condensate to flow out intermittently, thus failing to achieve the flocculation effect and preventing the colloidal substances in the condensate from settling. Therefore, we propose a closed-loop condensate recovery and flash evaporation utilization system. Utility Model Content

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figure 1-6 As shown, a closed-loop condensate recovery and flash evaporation utilization system includes a base 1 and a tank 2. The top of the tank 2 is located on the top of the base 1. The outer surface of the tank 2 is provided with an inlet pipe 3 and an outlet pipe 4. The top of the base 1 is provided with a control box 5. The system also includes a flocculation device 6. The flocculation device 6 includes a fixing plate 61, which is fixedly connected to the inside of the tank 2. The top of the fixing plate 61 is provided with a motor 62. The output shaft of the motor 62 is fixedly connected to a rotating shaft 63. A fixing ring 64 is fixedly connected to the circumferential surface of the rotating shaft 63. A stirring rod 65 is fixedly connected to the circumferential surface of the fixing ring 64. A feed valve 66 is provided on the circumferential surface of the tank 2.

[0028] The filter device 7 includes a filter plate 71, which is slidably connected to the inner wall of the tank 2. The inner wall of the tank 2 is provided with an activated carbon plate 72. This design is beneficial for the filter plate 71 to filter the condensate after flocculation.

[0029] A support plate 67 is fixedly connected to the inner wall of the tank body 2. A rectangular groove 68 is provided on the top of the support plate 67. One end of a spring 69 is fixedly connected to the inner wall of the rectangular groove 68. A slider 610 is fixedly connected to the end of the spring 69 away from the rectangular groove 68. A baffle 611 is fixedly connected to the side of the slider 610. An action plate 612 is fixedly connected to the circumferential surface of the rotating shaft 63. A through groove 613 is provided on the top of the support plate 67. This design is beneficial to the action plate 612, which can force the slider 610 to slide on the inner wall of the rectangular groove 68.

[0030] The inner wall of the tank 2 is provided with a groove 73. One end of a force spring 74 is fixedly connected to the inner wall of the groove 73. A force block 75 is fixedly connected to the end of the force spring 74 away from the inner wall of the groove 73. A circular plate 76 is fixedly connected to the circumferential surface of the rotating shaft 63. A blocking block 77 is fixedly connected to the circumferential surface of the circular plate 76. A force rod 78 is fixedly connected to the top of the filter plate 71. This design is beneficial to the blocking block 77 forcing the force rod 78 to move downward.

[0031] The dimensions of the baffle 611 are matched with the dimensions of the through groove 613. One end of the actuating plate 612 is set as an arc surface, and one end of the slider 610 is set as an arc surface. This design is conducive to the baffle 611 being able to intermittently open the through groove 613.

[0032] The force-bearing block 75 is slidably connected to the inner wall of the groove 73. There are two force-bearing blocks 75, which are symmetrical about each other along the vertical central axis of the tank body 2. This design is conducive to the sliding of the force-bearing block 75 on the inner wall of the groove 73.

[0033] The force-bearing block 75 is fixedly connected to the circumferential surface of the filter plate 71, and the force-bearing block 75 is slidably connected to the inner wall of the groove 73. This design is beneficial to the force-bearing block 75 driving the filter plate 71 to move.

[0034] The control box 5 has a partitioned structure inside, and the water inlet pipe 3 and the water outlet pipe 4 pass through the outer surface of the control box 5. Several stirring rods 65 are provided and are arranged in a circumferential array on the circumferential surface of the fixed ring 64. This design is conducive to the stirring rods 65 stirring the condensate with added flocculant.

[0035] According to the above structure, when the staff needs to recycle the condensate, since the condensate contains colloidal substances, a coagulant is added to cause the internal impurities to precipitate. The staff can control the condensate through the inlet pipe 3 and the control box 5 to enter the tank 2, and control the motor 62 to start, forcing the rotating shaft 63 to rotate clockwise. At this time, the staff can put the coagulant into the tank 2 through the feed valve 66. In order to make the coagulant and condensate fully mixed, when the rotating shaft 63 rotates, it forces the fixed ring 64 to drive the stirring rod 65 to rotate, so that the coagulant and condensate are fully mixed, and the substances inside the condensate are fully precipitated. When the rotating shaft 63 rotates, it can drive the action plate 612 to rotate, forcing the slider 610 to contact the action plate 612 and slide inside the rectangular groove 68 under force, thereby opening the through groove 613. The through groove 613 can be opened intermittently, so that when the coagulant and condensate are stirred, the stirred condensate can flow out intermittently, achieving the flocculation effect, and allowing the colloidal substances in the condensate to precipitate.

[0036] In the flocculation device 6, after the condensate flows out, in order to separate the water from the impurities, the impurities are filtered by the filter plate 71 when the condensate flows out. The filtered condensate then passes through the activated carbon plate 72, which adsorbs the molecules in the condensate that are not easily dissolved, thus achieving filtration of the condensate and making the condensate purer. In order to prevent the filter plate 71 from clogging, when the rotating shaft 63 rotates, it can drive the circular plate 76 to rotate, so that the block 77 moves with the circular plate 76. When the block 77 moves, the block 77 contacts the force rod 78, which allows the filter plate 71 to move through the force block 75. When the block 77 no longer contacts the force rod 78, the filter plate 71 is reset by the elastic force of the force spring 74, effectively ensuring that the filter plate 71 is not clogged.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
