Description

Technical Field

[0001] This utility model relates to the field of heat exchange system technology, specifically a screen-type solid waste heat exchange system. Background Technology

[0002] The heat exchange device fully exchanges heat and extracts high-temperature waste heat. The heat exchange system is divided into two relatively independent but fully coupled units: heat collection and heat exchange. The heat exchange unit adds a high-efficiency heat exchange medium or a medium required for secondary application, turning the heat into a usable end product for further production.

[0003] Solid preheating heat exchange systems treat the waste heat of solids through heat exchange structures. The residence time of solid particles in the heat exchange structure is short, resulting in insufficient heat transfer and affecting the heat exchange effect. The distribution of solid particles on the screen may be uneven, resulting in uneven contact with the heat exchange tubes and poor heat transfer in some areas. The flow of solid particles may be subject to resistance, affecting their uniform distribution and heat transfer, thus reducing the heat exchange efficiency of the solid waste heat exchange system. Utility Model Content

[0004] The purpose of this invention is to provide a screen-type solid waste heat exchange system to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is: a screen-type solid waste heat exchange system, including a cylinder, a top plate fixedly connected to the outer wall of the top end of the cylinder, a bottom plate fixedly connected to the outer wall of the bottom end of the cylinder, and further comprising;

[0006] A heat exchange mechanism is disposed on the inner wall of the cylinder.

[0007] The heat exchange mechanism includes an outer screen and an inner screen disposed on the inner wall of the cylinder. A plurality of heat exchange tubes are fixedly connected to the outer wall of the outer screen, and a plurality of heat exchange tubes are fixedly connected to the inner wall of the inner screen. Spiral grooves are formed on the outer walls of the outer and inner screens. A spiral heat-conducting plate is fixedly connected to the inner wall of the spiral grooves. A spiral heat-conducting tube is fixedly connected to the outer wall of the spiral heat-conducting plate. The spiral heat-conducting tubes are spaced at the same distance from the outer and inner screens.

[0008] Preferably, both heat exchange tube one and heat exchange tube two are arranged in a ring array, the spiral heat conduction tube and spiral heat conduction plate are adapted to the height of the outer screen and the inner screen, and the diameter of the outer screen is larger than the diameter of the inner screen.

[0009] Preferably, a feed hole is provided on one side of the outer wall of the top of the top plate, and a feed hopper is inserted into the inner wall of the feed hole. A discharge hole is provided on one side of the outer wall of the bottom of the bottom plate, and a discharge pipe is inserted into the inner wall of the discharge hole. Both the feed hopper and the discharge pipe are adapted to the size of the spiral heat-conducting plate.

[0010] Preferably, a water inlet pipe is provided on the outer wall of the top of the top plate and a water outlet pipe is provided on the outer wall of the bottom of the bottom plate, and a solenoid valve is installed on the inner wall of the water outlet pipe.

[0011] Preferably, the bottom outer wall of the top plate and the top outer wall of the bottom plate are provided with connection holes, the connection holes are adapted to the size of heat exchange tube one and heat exchange tube two, and the outer wall of the cylinder is provided with a heat insulation layer.

[0012] Preferably, the outer walls of the top and bottom ends of the first heat exchange tube are provided with heat insulation sheet one, and the outer walls of the top and bottom ends of the second heat exchange tube are provided with heat insulation sheet two, wherein the heat insulation sheet one and the heat insulation sheet two are respectively adapted to the size of the first heat exchange tube and the second heat exchange tube.

[0013] This utility model provides an improved screen-type solid waste heat exchange system, which has the following improvements and advantages compared with the prior art:

[0014] Firstly, this utility model comprises a cylinder, heat exchange tube one, heat exchange tube two, a spiral heat-conducting plate, a spiral heat-conducting pipe, an outer screen, and an inner screen. Solids slide down the inner wall of the outer screen and the outer wall of the inner screen. Cold water enters the heat exchange tube one and heat exchange tube two through the water inlet pipe. The heat exchange tubes one and two, arranged in a ring array, exchange heat with the solids attached to the outer and inner screens. The heat is absorbed and heats the water. As the solids slide down the spiral heat-conducting plate, the heat is continuously absorbed. The spiral descent and support on both sides by the spiral heat-conducting pipe ensure more uniform and comprehensive contact. The long path of the solids as they descend through the spiral heat-conducting plate results in a longer contact time. Furthermore, the spiral heat-conducting pipe pushes the solids to the sides, ensuring close contact with the outer and inner screens. This results in more uniform and comprehensive contact with the ring array of heat exchange tubes one and two, leading to better heat exchange performance and improved heat exchange efficiency of the screen-type solid waste heat exchange system.

[0015] Secondly, this utility model, by setting up heat insulation sheet one, heat insulation sheet two, and a heat insulation layer, and by setting heat insulation sheet one and heat insulation sheet two at the top and bottom of heat exchange tube one and heat exchange tube two respectively, prevents heat from being lost to the environment through the outer wall of the heat exchange structure, thereby ensuring that more heat is transferred to the heat exchange medium. The heat insulation layer set on the outer wall of the cylinder reduces the loss of internal heat, thus improving the practicality of the screen-type solid waste heat exchange system.

[0029] Furthermore, an inlet pipe 8 is provided on the outer wall of the top of the top plate 4, and an outlet pipe 10 is provided on the outer wall of the bottom of the bottom plate 5. A solenoid valve is installed on the inner wall of the outlet pipe 10.

The connection holes are adapted to the size of heat exchange tube 1 3 and heat exchange tube 2 7. An insulation layer 2 is provided on the outer wall of the cylinder 1. Heat insulation sheets 13 are provided on the outer walls of the top and bottom of heat exchange tube 1 3.

[0030] Working principle: During solid waste heat exchange, the solid to be heat-exchanged is fed into the cylinder 1 through the feed hopper 6 on the top plate 4. The solid falls onto the spiral heat-conducting plate 11 and moves to both sides of the spiral heat-conducting tube 12 on the spiral heat-conducting plate 11 through the arc surface of the spiral heat-conducting tube 12. The solid slides down against the inner wall of the outer screen 15 and the outer wall of the inner screen 16. Cold water enters the heat exchange tube 1 3 and heat exchange tube 2 7 through the water inlet pipe 8. The heat exchange tubes 1 3 and heat exchange tube 2 7, which are arranged in a ring array, exchange heat with the solid attached to the outer screen 15 and inner screen 16. The heat is absorbed to heat the water, and the solid passes through the spiral heat-conducting plate 11. The heat is continuously absorbed by the heat exchanger as the material descends spirally and is supported on both sides by the spiral heat-conducting pipe 12, resulting in more even and comprehensive contact. After a batch of heat exchange is completed, the solid material is output from the discharge pipe 9 at the bottom of the bottom plate 5. The solenoid valve in the water outlet pipe 10 is opened, and the heated hot water is output from the water outlet pipe 10. Then, a new batch of cold water is input for the next heat exchange process. Insulation plates 13 and 14 are respectively installed at the top and bottom of heat exchange pipe 1 3 and heat exchange pipe 2 7 to prevent heat from being lost to the environment through the outer wall of the heat exchange structure, thereby ensuring that more heat is transferred to the heat exchange medium. An insulation layer 2 is installed on the outer wall of the cylinder 1 to reduce the loss of internal heat.
