Description

Technical Field

[0001] This utility model relates to the technical field of supercritical units in thermal power plants, specifically a supercritical unit that utilizes waste heat from circulating water. Background Technology

[0002] Ultra-supercritical and supercritical units in thermal power plants refer to units where the parameters of the working fluid inside the boiler reach or exceed the critical pressure. The working fluid inside the boiler is water, whose critical pressure is 22.129 MPa and critical temperature is 374.15℃. At this pressure and temperature, the density of water that expands due to high temperature and water vapor that is compressed due to high pressure are the same, which is called the critical point of water. If the pressure of the working fluid inside the furnace is lower than this pressure, it is called a subcritical boiler, and if it is higher than this pressure, it is called a supercritical boiler. If the steam temperature inside the furnace is not lower than 593℃ or the steam pressure is not lower than 31 MPa, it is called ultra-supercritical. In engineering, pressures above 25 MPa are often referred to as ultra-supercritical. Since supercritical units use circulating water for power generation, after long-term circulation, the water temperature is low and certain chemical components are present. Corrosion and scaling will occur in the waste heat recovery device, affecting the service life and thermal efficiency of the equipment. Therefore, we propose a supercritical unit that reuses waste heat from circulating water. Utility Model Content

[0003] The purpose of this invention is to provide a supercritical unit for recycling waste heat from circulating water, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a supercritical unit for recycling waste heat from circulating water, including a base, a unit body disposed on the top of the base, water pipes connected to both ends of the unit body, a recovery component disposed in the middle of the water pipes, and a filter component disposed inside the recovery component.

[0005] The filter assembly includes a fixed box, an activated carbon adsorption layer, and a mesh box. Springs are fixedly connected to the four corners inside the fixed box. A telescopic column is set in the middle of the spring, and the other end of the spring is set on the outside of the shrink plate. The bottom of the inner side of the shrink plate is provided with a slot. There are a total of 4 fixed boxes, and the inner side of the fixed boxes is respectively provided with a primary filter element and a secondary filter element. The bottom of the front and rear sides of the primary filter element and the secondary filter element are fixedly connected with a locking block, and the locking block and the locking slot are interlocked. An activated carbon adsorption layer is provided on the right side of the primary filter element and the secondary filter element.

[0006] The recycling component includes an arc-shaped chamber and a filter chamber. A primary heat conduction plate is fixedly connected to the bottom of the arc-shaped chamber. A primary heat storage body is installed on the top of the primary heat conduction plate. A secondary heat conduction plate is installed on the top of the primary heat storage body. A secondary heat storage body is installed on the top of the secondary heat conduction plate.

[0007] The arc-shaped compartment has a heat transfer pipe on its left side, and the other end of the heat transfer pipe is connected to the unit body.

[0008] The mesh box has a rotating door rotatably connected to its front side, and an observation port is provided in the middle of the rotating door.

[0009] The revolving door has a handle on the back.

[0010] The front and rear sides of the activated carbon adsorption layer on the right are respectively locked inside the baffle.

[0011] Both the primary and secondary filter elements have hand grooves on their tops.

[0012] This utility model has at least the following beneficial effects:

[0013] First, install the filter cartridge inside the fixing box. The filter cartridge pushes the shrink plate up using the locking block. Once pushed to the bottom, the locking block and the slot snap together to fix the filter cartridge in place. As the water circulates through the water pipe, it passes through the primary filter cartridge, the secondary filter cartridge, and the activated carbon adsorption layer. In addition, chemical components placed inside the mesh box further adsorb and filter impurities in the water through the filter cartridge and activated carbon. At the same time, the chemical components placed inside the mesh box can neutralize or react with the chemical components in the water to achieve the desired chemical composition, further filtration and purification of the water, ensuring its cleanliness and preventing scale buildup.
