Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology of incinerators, specifically a heat pipe heat exchanger for waste heat recovery from incinerators. Background Technology

[0002] Waste heat recovery from incinerators is a technology that converts the heat energy in the high-temperature flue gas generated during the incineration of waste, biomass, and industrial waste into usable energy (steam, hot water, electricity, etc.), which can improve energy utilization by 30%-60% while reducing emission costs. Heat pipe heat exchangers are a type of efficient, passive heat exchange device that uses the phase change cycle (evaporation-condensation) of the working fluid inside the heat pipe to achieve rapid heat transfer.

[0003] According to a patent published on the China Patent Network, the patent title is: "A Heat Exchange Device for Waste Heat Utilization of Polycarboxylate Superplasticizer," patent application number: 201921764695.5. It includes a heat-conducting pipe and a second gas-conducting pipe. A waste heat collection mechanism is provided on one side of the heat-conducting pipe, and an inlet pipe is provided outside the waste heat collection mechanism. A first one-way valve is connected to one side of the inlet pipe via a key. An outlet pipe is provided on the other side of the waste heat collection mechanism. The second gas-conducting pipe is located at the lower end of the heat-conducting pipe, and a waste heat outlet pipe is welded to the lower end of the second gas-conducting pipe. This heat exchange device for waste heat utilization of polycarboxylate superplasticizer stores heat. The inner wall of the heat exchanger has heat dissipation holes, which can improve the heat dissipation effect of the heat storage heat exchanger and extend its service life. When the residual heat introduced by the heat conduction pipe is insufficient, the control valve can be opened. Under the action of the one-way pressure valve, the residual heat can be introduced into the heat storage heat exchanger through the heat conduction pipe for storage, which can make full use of effective resources, avoid resource waste, and is more environmentally friendly. In contrast, the heat pipe heat exchanger mentioned above generally uses copper for its conveying pipe, which is prone to oxidation in high-temperature environments. This leads to a lack of guarantee for the service life and performance of the heat pipe heat exchanger, affecting the heat exchange quality.

[0004] Therefore, it is necessary to redesign and modify the heat pipe heat exchanger to effectively prevent the easy oxidation of its delivery pipeline. Utility Model Content

A spring 6 is fixedly connected to the inner side of the fixed plate 5. A movable plate 7 is fixedly connected to the inner side of the spring 6. The inner side of the movable plate 7 is slidably connected to the hot and cold end assembly 2. A clamping plate 8 is fixedly connected to the inner side of the movable plate 7. An oxidation-resistant cover 9 is provided at the top and bottom of the surface of the heat pipe assembly 1. A thermal barrier coating strip 10 is fixedly connected to the surface of the oxidation-resistant cover 9. A connecting plate 11 is fixedly connected to the outer side of the oxidation-resistant cover 9. The inner side of the clamping plate 8 extends into the interior of the connecting plate 11.

[0032] refer to Figure 1 and Figure 3 A pressing mechanism 12 is slidably connected to the inner side of the connecting plate 11. The pressing mechanism 12 includes a slider 13. An L-shaped plate 14 is fixedly connected to the inner side of the slider 13. A pressing block 15 is fixedly connected to the outer side of the inner side of the L-shaped plate 14. The inner side of the pressing block 15 extends into the interior of the clamping plate 8. A pulling bent rod 16 is fixedly connected to the inner side of the L-shaped plate 14.

[0033] As a technical optimization of this utility model, the clamping mechanism 12 can limit the position of the card plate 8 and prevent it from falling off.

[0034] refer to Figure 3 An anti-slip sleeve 17 is fixedly connected to the surface of the pull rod 16, and the anti-slip sleeve 17 is used in conjunction with the pull rod 16.

[0035] As a technical optimization of this utility model, the anti-slip sleeve 17 makes it easier for users to pull the bending rod 16, thus increasing user convenience.

[0036] refer to Figure 3 A vertical groove 18 is provided on the inner side of the connecting plate 11, and the outer side of the slider 13 is slidably connected to the inside of the vertical groove 18.

[0037] As a technical optimization of this utility model, the vertical groove 18 enables the slider 13 to slide more smoothly inside the connecting plate 11, reduces the friction between the slider 13 and the connecting plate 11, extends the service life of the slider 13, and at the same time limits the slider 13.
