Description

[0002] In the process of industrial production, many processes relying on boiler operation will generate a large amount of high-temperature and high-pressure steam. As an important heat source device in industrial production, if the steam generated by the boiler is directly discharged, it will not only cause great waste of energy, but also may have an adverse impact on the environment. The functions of traditional boiler temperature and pressure reduction devices are relatively single, often only able to achieve the operations of reducing the temperature and pressure of steam, and unable to effectively recover the large amount of waste heat carried by the steam. This results in low energy utilization efficiency and increased production costs for enterprises. At the same time, some existing boiler waste heat recovery devices have problems of complex structure and high cost. The complex structure makes the installation and maintenance of the device in the boiler system more difficult, and the high cost limits its large-scale popularization and application. Moreover, in terms of adjusting the steam flow rate and water flow rate, existing devices usually lack a precise and flexible adjustment mechanism, and it is difficult to adjust in real time according to the actual production requirements of the boiler, thereby affecting the effects of temperature and pressure reduction and waste heat recovery. To solve the above-mentioned problems, there is an urgent need to develop an integrated device for reducing temperature and pressure of a boiler with a reasonable and simple structure, low production cost, convenient installation, and capable of efficiently recovering waste heat and precisely adjusting the steam and water flow rates, so as to improve energy utilization efficiency, reduce the operating costs of enterprises, and meet the requirements of modern industrial production for energy conservation, environmental protection, and efficient operation.

[0033] Among them, the second motor 728 is a servo motor or a stepper motor.

[0034] The usage state of the present invention is as follows: The present invention has a reasonable and simple structure, low production cost, and convenient installation. When in use, first, high-temperature steam enters from the input joint 49. The input joint 49 is connected to the central opening on the left side of the circular cavity 47 of the input housing 45. After the steam enters the circular cavity 47, it is evenly distributed and conveyed to the conical hole 44 in the center of the conical hole block 43 through several diversion holes 46 opened around the right side of the circular cavity 47. There are multiple conical hole blocks 43, and their outer parts are respectively movably connected to the guide holes 42 inside the periphery of the guide hole seat 41. The right side of the guide hole seat 41 is fixedly connected to the left side of the connecting seat 1. At this time, the steam will flow along the outside of the heat exchange conical cover 3. If it is necessary to adjust the steam flow rate, start the telescopic adjustment mechanism 48. The motor 481 in the telescopic adjustment mechanism 48 is fixedly connected to the center on the right side of the guide hole seat 41. The operation of the motor 481 drives the screw 483 to rotate. The screw 483 is movably connected to the guide hole 482 inside the left center of the guide hole seat 41. Since the outside of the telescopic seat 484 is horizontally movably connected to the inside of the guide hole 482, and the threaded hole provided in the center thereof is connected to the screw 483, and the left end of the telescopic seat 484 is fixedly connected to the center on the right side of the input housing 45, the operation of the motor 481 can drive the input housing 45 to move left and right, thereby adjusting the gap between the conical hole 44 and the outside of the heat exchange conical cover 3, and realizing the adjustment of the steam flow rate.

Its right inlet is communicated with the lower left side of the storage cavity 713, and its left outlet is connected to the central opening on the right side of the circular cavity 7111. The circulating pump 7110 conveys the water in the storage cavity 713 to the circular cavity 7111. Several diversion holes 7112 opened around the left side of the circular cavity 7111 are respectively fixedly connected to the outside of the right side of the corresponding fixed pipe 76. After the water is diverted through the diversion holes 7112, it enters the fixed pipe 76.

During this process, heat exchange is carried out with the steam. There are multiple heat exchange conical covers 3, and their right openings are respectively evenly fixedly connected to the periphery inside the circular groove 1. This structure increases the heat exchange area and enhances the effect of steam temperature reduction and pressure reduction. If it is necessary to adjust the water flow rate, start the synchronous adjustment mechanism 72. The motor 728 in the synchronous adjustment mechanism 72 is fixedly connected to the upper right side of the connecting seat 1. The operation of the motor 728 drives the driving gear 727 to rotate. The driving gear 727 is connected to the upper side of the external gear 725 on the outside of the left side of the movable ring body 726, thereby driving the movable ring body 726 to rotate. The movable ring body 726 is movably connected to the inside of the periphery on the right side of the connecting seat 1.The internal gear 724 fixedly connected to its left side is connected to the driven gear 723. The driven gear 723 is fixedly connected to the right end of the second screw 722. The second screw 722 is movably connected inside the third guide hole 73. When the movable ring body 726 rotates, the driven gear 723 is driven to rotate by the internal gear 724, and then the second screw 722 rotates. Since the internal thread 721 is provided inside the right side of the movable cone 77 and the second screw 722 cooperates with the internal thread 721, the rotation of the second screw 722 can drive the movable cone 77 to move left and right, adjusting the gap between the outside of the movable cone 77 and the inside of the heat exchange cone cover 3, realizing the adjustment of the water flow rate, and further improving the effect of steam desuperheating and decompression. The second motor 728 can be a servo motor or a stepper motor. After the heat exchange is completed, the desuperheated and decompressed steam enters the first circular groove 2. A connection seat 1 is provided on the left side of the first circular groove 2, and an output joint 6 is provided at the upper opening. The steam is output through the output joint 6. The water that recovers heat is communicated with the communication hole 75 through the inside of the right side of the heat exchange cone cover 3, and then enters the first annular hole 74. The first annular hole 74 is located outside the third guide hole 73 and is provided inside the connection seat 1. The right sides of multiple first annular holes 74 are communicated with the left side of the second annular hole 79. The second annular hole 79 is provided around the center of the right side of the connection seat 1. Its lower opening is connected to the upper left opening of the return channel 712 inside the lower side of the water tank housing 711 through a pipeline. The water enters the return channel 712 from here. A storage cavity 713 is provided inside the upper side of the water tank housing 711. The lower right side of the storage cavity 713 is communicated with the right side of the return channel 712 through the connection hole 715.
