Description

Technical Field

[0001] The utility model relates to the technical field of energy recovery, and in particular to an energy-saving converter waste heat steam comprehensive utilization device. Background Art

[0002] A steam comprehensive utilization device is a device that can convert the thermal energy and kinetic energy of input steam into other energy forms and output them to the outside. In the production process of factories such as steel mills, water is often used as a cooling medium for finished workpieces. After being used for cooling, water will evaporate due to the high temperature. At this time, the high-temperature water vapor can be absorbed and guided by the steam comprehensive utilization device, and the upward kinetic energy of the steam can be fully utilized. At the same time, the thermal energy of the water vapor can be conducted and absorbed through the built-in heat pipe, thereby reducing the factory's production energy consumption and reducing production costs in disguise. At the same time, due to less energy consumption, pollution can be reduced, making factory production more environmentally friendly.

[0003] Although the above-mentioned prior art can solve the corresponding technical problems, it still has certain defects: when the existing steam comprehensive utilization device recycles the steam generated in the ironmaking workshop containing a lot of dust, after the steam enters the comprehensive utilization device, it will also cause part of the dust to enter the comprehensive utilization device along with the steam, and then adhere to the surface of the heat pipe of the comprehensive utilization device, and combine with the water vapor to gradually form an adhesion layer, which greatly reduces the contact efficiency and thermal conductivity efficiency between the heat pipe and the water vapor, resulting in a significant decrease in the heat energy recovery efficiency of the water vapor, and requires frequent shutdowns and manual cleaning, which is relatively complicated and cumbersome to use. Utility Model Content

[0004] The utility model aims to provide an energy-saving converter waste heat steam comprehensive utilization device with high heat recovery efficiency and convenient use and cleaning in view of the defects and shortcomings of the prior art.

[0006] A further improvement is that a truncated cone-shaped outward expansion pipe is provided at the lower end of the steam pipe.

[0007] Further improvement: The dropdown frame includes a chassis that fits and is detachably arranged at the bottom of the recovery bin, and a connecting rod arranged on the top surface of the chassis. A cleaning ring that fits and is slidably connected to the outer wall of the heat energy recovery pipe is provided at the top end of the connecting rod.

[0008] Further improvement: A sealing ring is provided on the outer wall of the chassis.

[0011] Further improvement: The cleaning ring includes a ring body and a receiving inner cavity integrally formed within the ring body.

[0012] Further improvement: A lower scraping block is provided at the bottom of the ring body.

[0013] Further improvement: An upper scraping block is provided at the top of the ring body.

[0014] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: During the use of the present utility model, if attachments are generated on the surface of the heat energy recovery pipe, the dropdown frame can be quickly pulled down, so that the cleaning ring moves along the surface of the heat energy recovery pipe, thereby scraping and removing the attachments on the surface of the heat energy recovery pipe.

At this time, a large amount of heat in the steam can be absorbed and conducted to recover heat energy. Then the steam continues to move and the impact force generated by the steam movement is applied to the kinetic energy recovery machine 5, causing it to rotate and generate electricity, converting the steam kinetic energy into electrical energy, and then the steam is discharged from the exhaust pipe 6. At this time, the heat energy and kinetic energy of the steam can be recycled. After a period of use, if an adhesion layer is generated on the surface of the heat recovery pipe 3, there is no need to stop the machine. At this time, the lower pull frame 4 is directly pulled downward from the recovery bin 2 to separate it from the recovery bin 2, thereby moving the chassis 41 downward, and then the cleaning ring 44 can be driven by the connecting rod 43 to move downward along the surface of the heat recovery pipe 3, so that the ring body 441 scrapes off the attachments on the surface of the heat recovery pipe 3 during the downward movement, and makes it fall onto the chassis 41, and then the heat recovery pipe 3 can be quickly cleaned during use to ensure the contact heat absorption effect between the heat recovery pipe 3 and the steam, and make cleaning and maintenance simpler and more convenient;

At this time, a large amount of heat in the steam can be absorbed and conducted to recover heat energy. Then the steam continues to move and the impact force generated by the steam movement is applied to the kinetic energy recovery machine 5, so that it rotates to generate electricity, converting the kinetic energy of the steam into electrical energy. Then the steam is discharged from the exhaust pipe 6. At this time, the thermal energy and kinetic energy of the steam can be recycled.
