Description

Technical Field

[0001] The present invention relates to the technical field of waste heat recovery, and in particular to a multi-source integrated deaerator exhaust steam waste heat recovery device and method. Background Art

[0002] The multi-source integrated deaerator exhaust steam waste heat recovery device is an advanced energy-saving equipment that recovers the flash steam (exhaust steam) discharged from the deaerator in the form of hot water or steam and reuses it in the system to reduce energy waste and environmental pollution, and achieve efficient energy utilization and environmental protection.

[0003] After searching, the Chinese patent with publication number CN219932270U is: a waste steam heat recovery device, including a waste steam heat recovery device body, an exhaust pipe is arranged on the top of the waste steam heat recovery device body, an overflow pipe is arranged inside, a silencer structure is installed on the exhaust pipe, and a filter structure is installed on the overflow pipe. By arranging the silencer structure on the exhaust pipe, the waste steam heat recovery device can effectively reduce the noise when exhausting, and the filter structure is arranged on the top of the overflow pipe, so that the waste steam heat recovery device is not easy to be blocked after long-term use. However, the above technical solution still has the following shortcomings when implemented: Unstable pressure: Since the air inlet of the tank is a multi-source interface, the exhaust steam flows into the connecting pipe from multiple connection ports. The exhaust steam in the connecting pipe cannot be transported to the tank in the first time, which will cause the pressure in the connecting pipe to increase, and then affect the stability of the connection between the connecting pipe port and the deaerator. There is a risk of leakage over time; (2) Uneven distribution of exhaust steam: Since gas has the characteristics of floating heat and cooling down, the exhaust steam gathered in the tank will be unevenly distributed in the upper and lower parts. As a result, when the heat conversion is carried out in the same time, the conversion amount of the exhaust steam with higher heat is lower, resulting in partial heat waste; (3) Low heat conversion efficiency: Since the exhaust steam flows continuously in the pipeline, the exhaust steam stays in the pipeline for a short time, which shortens the heat exchange time between the exhaust steam and the external medium, thus affecting the heat exchange efficiency and causing heat waste; Therefore, it is necessary to design a multi-source integrated deaerator exhaust steam waste heat recovery device and method to solve the above problems.

[0022] Reference Figure 4 and Figure 6 The opening and closing assembly includes a central plate 801 fixedly connected to the inner wall of the heat-conducting pipe 6, a fan plate 802 is rotatably connected to the side of the central plate 801, a push rod 803 is hinged on the surface of the fan plate 802, a ring 805 is hinged on the end of the push rod 803 away from the fan plate 802, a T-shaped rod 804 is fixedly connected to the middle of the central plate 801, the ring 805 is movably sleeved on the outer surface of the T-shaped rod 804, and a spring 806 is sleeved on the outer surface of the T-shaped rod 804.

[0023] A method for recovering waste heat from exhaust steam of a multi-source integrated deaerator is provided, using the above-mentioned device for recovering waste heat from exhaust steam of a multi-source integrated deaerator, and the method of use is as follows: S1, gas gathering: multiple interfaces 3 on the outer surface of the connecting pipe 2 are connected to the deoxygenator, the exhaust steam enters the connecting pipe 2 through the interface 3 and drives the balance component to operate, the exhaust steam is gathered and discharged into the tank body 1; S2, mixing and dispersing: After the motor 701 is started, the motor 701 drives the mixing component to operate, and the rotation of the fan blades 710 accelerates the flow of the exhaust steam in the tank body 1 and mixes the exhaust steam, and at the same time disperses and transports the exhaust steam into each heat pipe 6; S3, heat conduction: after the exhaust steam enters the heat pipe 6, it will exchange heat with the medium in the sleeve 5, and with the cooperation of the opening and closing components, the residence time of the exhaust steam in the heat pipe 6 is extended, thereby improving the efficiency of waste heat utilization; S4, discharge: the exhaust steam after waste heat recovery flows into the tank body 1 and is finally discharged from the discharge pipe 9.

[0024] The specific working principle of the present invention is as follows: The multi-source integrated deaerator exhaust steam waste heat recovery device and method proposed in the present invention are composed of a tank body 1, a connecting pipe 2, a sleeve 5 and a heat conducting pipe 6. The exhaust steam enters the tank body 1 through the connecting pipe 2, and the heat flowing from the heat conducting pipe 6 is suitable for heat transfer with the medium in the sleeve 5 to achieve the effect of heat recovery. Multiple exhaust steam enters the connecting pipe 2 from the interface 3 of the connecting pipe 2. The flow of exhaust steam will impact the blade 407 and push the blade 407 to drive the round wheel 406 and the cylinder 404 to rotate. Since the round rod 403 is movably inserted in the cylinder 404, the exhaust steam will be discharged from the cylinder 404. The slider 408 on the surface of the round rod 403 slides in the slide groove 409 on the inner wall of the cylinder 404, so the cylinder 404 will drive the round rod 403 to reciprocate along the inner wall of the cylinder 404 during the rotation process. The round rod 403 will push the pressure relief pipe 402 to move and stretch or squeeze the bellows 401 while moving, thereby achieving the purpose of relieving the exhaust steam in the connecting pipe 2, and after the pressure is relieved, it will be agitated again to help the exhaust steam flow from the connecting pipe 2 into the tank body 1, ensuring the stability of the connection between the connecting pipe 2 and the deaerator; The exhaust steam enters the tank body 1 and gathers. The operation of the motor 701 will drive the bevel gear 1 702 to rotate. The rotation of the bevel gear 1 702 will also drive the bevel gear 2 703 to rotate. Since the bevel gear 2 703 is connected to the double pulley 705 through the support rod 704, the double pulley 705 will rotate accordingly. During the rotation of the double pulley 705, the single pulley 706 will be driven to rotate through the belt 707. The single pulley 706 will then drive the fan blades 710 to rotate through the transmission rod 709. The fan blades 710 are distributed in a ring inside the tank body 1 and are arranged at the end of the heat pipe 6. The synchronous rotation of multiple fan blades 710 will disrupt and mix the exhaust steam in the tank body 1, and evenly send the mixed exhaust steam into the heat pipe 6, so that the exhaust steam temperature in each heat pipe 6 is the same, thereby ensuring that the exhaust steam can be stably The heat is transferred to improve the heat utilization efficiency. The exhaust steam enters the heat pipe 6 and transfers heat with the medium in the sleeve 5. Since the other end of the heat pipe 6 is blocked by the opening and closing component, the exhaust steam stays in the heat pipe 6. As the exhaust steam amount increases, the pressure in the heat pipe 6 increases, which will push the fan plate 802 to rotate around the center plate 801. At the same time, the push rod 803 will push the ring 805 to slide along the T-bar 804 and squeeze the spring 806. The rotation of the fan plate 802 causes the heat pipe 6 to open, and the exhaust steam is discharged. At this time, the pressure in the heat pipe 6 decreases, and the rebound of the spring 806 will push the fan plate 802 to reset and close the heat pipe 6. This reciprocating cycle can increase the residence time of the exhaust steam in the heat pipe 6, thereby achieving the effect of improving the exhaust steam waste heat conversion efficiency.
