Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, and more specifically, to a device for reusing waste heat from flue gas of a gas generator set. Background Technology

[0002] The waste heat recovery device for gas generator sets is a key piece of equipment for improving energy efficiency. It can efficiently recover and reuse the waste heat in the flue gas emitted by the unit. The waste heat recovery heat exchanger is the core heat transfer equipment of the waste heat recovery system, which is specially designed to recover medium and high temperature waste heat in the flue gas emitted by the unit. Its main body consists of heat transfer tube bundles, shell, inlet and outlet headers, ash removal device and insulation layer. Metal or corrosion-resistant materials can be selected according to the temperature and composition of the flue gas. During operation, high temperature flue gas enters the shell side or tube side of the heat exchanger through the inlet. When flowing over the heat transfer surface, it releases heat. The medium water is introduced from the other side in reverse. It absorbs heat from the flue gas through the tube wall and is heated to the required temperature. The low temperature flue gas after heat exchange is discharged through the outlet. The heated medium is transported to the subsequent system for use. The ash removal device runs regularly to remove the ash accumulation on the heat transfer surface to maintain high heat exchange efficiency and realize the continuous recovery of waste heat from the flue gas. Since the heated medium needs to be connected to the external pipeline for transportation, it is necessary to carry out connection protection operation.

[0003] In related technologies, during the use of flue gas waste heat recovery devices, the installation and connection between the device and external pipelines are generally carried out using a flange and multiple bolts.

[0004] However, during the current use of flue gas waste heat recovery devices, the connecting flanges and bolts are located on the outside and are easily corroded by external sewage and rainwater, which can lead to rust and damage at the connection points of the flue gas waste heat recovery device, affecting the connection effect and protection of the device.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4 This utility model provides a technical solution: a waste heat recovery device for flue gas from a gas generator set, including a heat exchanger 1 and a connecting liquid-blocking mechanism. Gas heads 2 are installed on both sides of the heat exchanger 1, and external pipes 3 are installed on both sides of the front side of the heat exchanger 1. A medium can be formed on the top of the external pipes 3 to block external sewage and rainwater, so that the user can perform liquid-blocking protection operation on the external pipes 3 during operation, avoiding damage to the external pipes 3 due to external sewage and rainwater erosion. Therefore, the connection effect and protection of the heat exchanger 1 are improved.

[0031] Reference Figures 1-4 In a preferred embodiment, the connecting liquid-blocking mechanism includes a liquid-blocking disc 4, which is movably connected to the top of the outer pipe 3. Support rods 5 are fixedly connected to the rear sides of both bottom sides of the liquid-blocking disc 4. A clamping rod 6 is movably connected to the bottom of the support rods 5. A clamping disc 7 is movably connected to the inner side of the support rods 5. A clamping stabilizing mechanism is movably connected to the bottom right side of the support rods 5. The liquid-blocking disc 4 is moved to the top of the outer pipe 3, and the support rods 5 are positioned outside the outer pipe 3. Then, the clamping rod 6 is flipped to the bottom of the two support rods 5, and the clamping disc 7, in conjunction with the clamping rod 6 and support rods 5, stabilizes the liquid-blocking disc 4 and the outer pipe 3. The clamping and installation work is carried out so that the liquid-blocking plate 4 can perform liquid-blocking protection. The clamping and stabilizing mechanism includes a stabilizing plate 8, a stabilizing column 9, and a stabilizing groove 10. The stabilizing plate 8 is movably connected to the bottom right side of the support rod 5, and the stabilizing column 9 is fixedly connected to the bottom left side of the stabilizing plate 8. The stabilizing groove 10 is opened on the right side of the clamping rod 6, and the left side of the stabilizing column 9 is located inside the stabilizing groove 10. This can stabilize the clamping connection between the clamping rod 6 and the support rod 5, and prevent the clamping rod 6 from shifting position during operation, which would make it difficult for the clamping rod 6 to stably cooperate with the clamping plate 7 for clamping work. Therefore, the working stability of the clamping rod 6 is improved.

[0032] Reference Figures 2-3In a preferred embodiment, a translation hole 11 is provided at the top right side of the stabilizing plate 8. A translation rod 12 is movably connected inside the translation hole 11. The left side of the translation rod 12 is fixedly connected to the right side of the support rod 5. This allows for translational connection between the stabilizing plate 8 and the support rod 5, preventing situations where the stabilizing plate 8 is difficult to connect with the support rod 5 and ensuring a stable connection between the clamping rod 6 and the support rod 5. This improves the connection effect between the stabilizing plate 8 and the support rod 5. A magnetic strip 13 is embedded at the top of the inner wall of the translation hole 11, and a magnetic strip 14, magnetically connected to the magnetic strip 13, is embedded at the top of the translation rod 12. This allows for magnetic positioning between the moved stabilizing plate 8 and the translation rod 12, thus improving the working stability of the stabilizing plate 8.

[0033] Reference Figures 2-4 In a preferred embodiment, a threaded groove 15 is provided at the bottom of the support rod 5 on the left side of the top of the clamping rod 6. The threaded groove 15 is connected to a screw 16 that extends to the bottom of the clamping rod 6, which allows for a rotatable connection between the clamping rod 6 and the support rod 5. This improves the connection effect between the clamping rod 6 and the support rod 5. A screw cylinder 17 is fixedly connected to the rear side of the top of the baffle plate 4. A stud 18 is connected to the threaded part of the screw cylinder 17, which can apply a clamping force to the clamping plate 7, avoiding the situation where it is difficult to apply force to clamp the clamping plate 7 during use. This improves the clamping effect of the clamping plate 7.

[0034] Reference Figures 2-4 In a preferred embodiment, by movably connecting a rotating cylinder 19 to the outside of the screw barrel 17, and fixing the top of the stud 18 to the inner wall of the rotating cylinder 19, a medium for rotating the stud 18 can be provided for the user, and the stud 18 and the screw barrel 17 can be surrounded and protected, thus improving the ease of operation and protection of the stud 18. Movable sleeves 20 are fixedly connected to both sides of the top of the clamping disk 7, and a movable seat 21 located inside the movable sleeve 20 is fixedly connected to the bottom of the stud 18, which can rotate and prevent separation between the stud 18 and the clamping disk 7, thus improving the connection effect between the stud 18 and the clamping disk 7.

[0035] Specifically, the working process or principle of this waste heat recovery device for gas generator sets is as follows: During use, the hand-held baffle plate 4 is moved to the top of the external pipe 3 connected to the external pipeline, and the support rod 5 is positioned outside the external pipe 3. Then, the hand-held clamping rod 6 is rotated to the bottom of another support rod 5, so that the clamping rod 6 cooperates with the support rod 5 to form a clamping frame on the outside of the external pipe 3, preparing for subsequent clamping with the clamping plate 7. At this time, the screw 16 engages with the screw groove 15 to rotate and connect the clamping rod 6 and the support rod 5. Subsequently, the hand-held stabilizing plate 8 drives the stabilizing column 9 to move to the left and into the stabilizing groove 10, stabilizing the clamping rod 6 and the support rod 5. At this time, the translation rod 12 moves inside the translation hole 11 to perform translational connection between the stabilizing plate 8 and the support rod 5. At this time, the magnetic strip 14, together with the magnetic suction strip 13, uses the translation rod 12 to magnetically position the stabilizing plate 8 and the stabilizing column 9 during operation. Then, the hand-held rotating drum 19 rotates the stud 18 in conjunction with the screw cylinder 17 to apply a downward threaded thrust to the clamping plate 7. At this time, the movable seat 21, together with the movable sleeve 20, connects the clamping plate 7 and the stud 18 to prevent separation, so that the clamping plate 7, together with the clamping rod 6, clamps and installs the liquid-blocking plate 4 at the top of the connection of the outer pipe 3. During this process, since the clamping plate 7 and the clamping rod 6 are fixedly connected with anti-slip pads, the clamping plate 7, the clamping rod 6 and the outer pipe 3 can be clamped and stabilized during operation, so that the liquid-blocking plate 4 is clamped and stabilized at the top of the outer pipe 3, forming a dirt-blocking medium to block and protect against external dirt and rainwater, ensuring the connection protection of the outer pipe 3.

[0036] It should be noted that heat exchanger 1, gas head 2 and external pipe 3 are existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
