Description

Technical Field

[0001] The utility model relates to the technical field of heat recovery, in particular to a heat dissipation recovery device for waste heat pipes of gas power generation. Background Art

[0002] Gas power generation is a method of using gas or natural gas generated in industrial processes such as coal mines and oil fields as fuel. The gas or natural gas is converted into mechanical energy through an internal combustion generator, and then into electrical energy. A large amount of heat is generated during gas power generation. In order to avoid the waste of heat generated by gas power generation, the heat is recovered and reused by adopting corresponding equipment.

[0003] The existing waste heat recovery device usually adopts waste heat recovery pipes for preheating recovery. When the existing waste heat recovery pipes are used for waste heat recovery, the waste heat pipes are straight pipes. The length of the straight pipes is limited. If the straight pipes are laid too long, not only will the pipe setting be wasted, but also the heat will be wasted when it is transported inside the longer pipes. When a shorter waste heat recovery pipe is designed, the heat recovery amount is small, and the transmitted heat will also be volatilized and wasted along the outer wall of the pipe. For this reason, we provide a gas power generation waste heat pipe heat dissipation recovery device to solve the above problems. Utility Model Content

[0004] 1) Technical problems solved

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a heat dissipation recovery device for waste heat pipes of gas power generation.

[0006] 2) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a heat dissipation and recovery device for waste heat pipes of gas power generation, comprising a recovery frame, wherein the recovery frame is composed of a cover plate and a base plate, and a support body is connected between the cover plate and the base plate. A multi-layer recovery pipe is arranged inside the frame, and a transmission branch pipe is passed between the multi-layer recovery pipes. The recovery pipe at the bottom is connected to the outside of an inlet pipe, and the recovery pipe at the top is connected to the outside of an exhaust pipe. The recovery pipe is a meandering pipe, and the two sections of the recovery pipe connected to the transmission branch pipe are exhaust acceleration sections, and the other two sections of the recovery pipe are insulation sections, and two adjacent insulation sections are connected to insulation parts.

[0008] Furthermore, the diameter of the exhaust acceleration section gradually decreases toward the pipe opening of the transmission branch pipe.

[0009] Furthermore, the insulation component includes a lower insulation sac wrapped on the insulation section, an upper insulation sac wrapped on the adjacent insulation section, a recessed area is provided on the top of the lower insulation sac, a protrusion is installed on the bottom of the upper insulation sac, and both the recessed area and the protrusion are provided with disconnecting grooves, and the protrusion is inserted into the recessed area.

[0010] Furthermore, the exteriors of the upper heat-insulating bladder and the lower heat-insulating bladder are both provided with concave groove sections.

[0011] Furthermore, a fitting body is installed at the joint of the upper heat-insulating bladder and the lower heat-insulating bladder.

[0012] Furthermore, a fixed seat plate is connected to the bottom of the support body, and a compression section is provided in the middle part of the support body.

[0013] 3) Beneficial effects:

[0014] Compared with the existing technology, the heat dissipation recovery device for waste heat pipes of gas power generation has the following beneficial effects:

[0015] 1. The utility model increases the transmission length of the heat recovery pipe by designing the pipe for recovering heat as a meandering recovery pipe, thereby increasing the amount of waste heat recovered. At the same time, the transmission branch pipe is designed to increase the connectivity between each layer of recovery pipes, so that the recovered heat is initially transferred from the bottom to the top for discharge, which is in line with the flow direction of heat upward transmission. At the same time, the insulation component is designed to be detachable, thereby increasing the insulation effect of the heat recovery pipe and avoiding the volatilization of heat along the outer wall of the recovery pipe.

[0016] 2. The utility model designs the lower insulation bladder and the upper insulation bladder to engage with each other, and then increases the fitting density of the lower insulation bladder and the upper insulation bladder through the designed fitting body, thereby reducing heat volatilization. At the same time, the concave groove sections opened in the lower insulation bladder and the upper insulation bladder increase the accumulation of heat along the heat, thereby avoiding heat volatilization during rapid heat transmission.

[0017] 3. The compression body on the support body can keep the multi-layer recovery pipes installed inside the recovery frame compact, thereby avoiding the recovery pipes from spreading out. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The utility model discloses lower heat preservation capsule and upper heat preservation capsule.

[0024] As Figures 1-4 The utility model provides a kind of technical scheme: a gas power generation waste heat pipe heat dissipation recovery device, the main scheme of this application is to recover and utilize waste heat when gas power generation, waste heat recovery pipeline design is unreasonable, the design including recovery frame adopted, the recovery frame is made of cover plate 1 and base plate 2, and cover plate 1 is connected with the support body 3 between bottom seat plate, the support body 3 bottom is connected with fixed seat plate 31, and support body 3 middle part is equipped with compression section 32.The frame is equipped with multiple recovery pipelines 4 inside, multiple recovery pipelines are distributed in the frame inside, by filling and discharging in compression section 32, compression section 32 adopts air pressure type, when filling, compression section 32 shrinks frame, so that multiple recovery pipelines 4 appear to move, slack condition is avoided, part of air in compression section 32 is discharged, so that compression section 32 is opened, and then the condition that recovery pipeline 4 is pressed to break is avoided.

[0025] And multiple recovery pipelines 4 are communicated by transmission branch pipe 5, recovery pipeline 4 outside located in bottom is communicated with inlet pipe 6, recovery pipeline 4 outside located in top is communicated with discharge pipe 7, the recovery pipeline 4 is serpentine pipeline, two sections of recovery pipeline 4 and transmission branch pipe 5 are communicated and are exhaust acceleration section 41, and other two sections of recovery pipeline 4 are heat preservation section 42, and heat preservation piece 8 is connected on two adjacent heat preservation sections 42.

[0026] Exhaust acceleration section 41 is conical tubular, and the diameter of the pipe opening of exhaust acceleration section 41 towards transmission branch pipe 5 gradually reduces.

[0027] The heat preservation part 8 comprises a lower heat preservation capsule 81 wrapped on a heat preservation section 42, and an upper heat preservation capsule 82 wrapped on the heat preservation section 42 adjacent to the lower heat preservation capsule 81, wherein a recessed area 83 is formed on the top of the lower heat preservation capsule 81, a protruding body 84 is installed on the bottom of the upper heat preservation capsule 82, and the recessed area 83 and the protruding body 84 are both provided with a disconnection slot 85, and the protruding body 84 is inserted into the recessed area 83.

[0028] A concave groove section 86 is formed on the outside of the upper heat preservation capsule 82 and the lower heat preservation capsule 81, so that the heat is stored in the concave groove section 86 when the heat passes through, and a sticking body 87 is installed on the joint of the upper heat preservation capsule 82 and the lower heat preservation capsule 81.

[0029] Working principle: After gas power generation, the heat generated needs to be recovered and processed. First, the frame is installed at the tail of the power generation equipment, and the fixed seat plate 31 at the bottom of the support body 3 is aligned with the installation position. There is a mounting hole on the fixed seat plate 31. The mounting hole is aligned with the mounting seat of the power generation equipment, and then the fixed seat plate 31 is fixed to the tail of the gas power generation equipment through the mounting hole by bolts or screws. Then, the recovery pipes 4 are connected layer by layer, and the disconnecting notches 85 in the recessed area 83 of the lower insulation bag 81 of the adjacent recovery pipes 4 are broken open, and then escape into the lower insulation bag 81 along the bottom of the recovery pipe 4, and then the upper The heat-insulating sac 82 is wrapped around the upper recovery pipe 4 along the disconnected notch 85, and then the protrusion 84 of the upper heat-insulating sac 82 is inserted into the inside of the recessed area 83, and the multi-layer recovery pipe 4 is wrapped in turn. When both sides of all the recovery pipes 4 are completely wrapped by the upper heat-insulating sac 82 and the lower heat-insulating sac 81, the recesses on both sides of the upper heat-insulating sac 82 and the lower heat-insulating sac 81 are distributed, and the fitting body 87 is completely cut into the recesses, and then the upper heat-insulating sac 82 and the lower heat-insulating sac 81 are kept completely fitted. After all the recovery pipes 4 are installed, the support body 3 is passed through the support body 3 to complete the installation. A certain amount of gas is introduced, so that the cover plate 1 presses the upper recovery pipe 4, thereby facilitating the recovery pipe 4 to remain in contact. The two corners of the multi-layer recovery pipe 4 are installed through the transmission branch pipe 5, thereby facilitating the mutual communication of the multi-layer recovery pipe 4. The recovery pipe 4 at the bottom is connected to the inlet pipe 6, and the inlet pipe 6 is connected to the waste heat discharge port of the gas power generation. After the heat enters the recovery pipe 4, since the exhaust acceleration section 41 of the recovery pipe 4 is in the shape of a cone, the heat entering in this way enters along the pipe with a large opening diameter, and the pipe opening diameter gradually decreases toward the corner, so that the heat inside the pipe can be rapidly concentrated. The heat then flows along the transmission branch pipe 5 toward the recovery pipe 4 on the upper layer. Part of the heat enters the two sides, and then enters the recovery pipe on the upper layer from the transmission branch pipe 5 at the corner through the exhaust acceleration section 41 on the other side. In this way, the multi-layer recovery pipe 4 can gradually add heat and completely rush into the recovery pipe 4, thereby increasing the heat recovery utilization rate, thereby effectively avoiding the existing pipe design being too short and increasing the recovered heat. At the same time, the designed upper insulation bladder 82 and the lower insulation bladder 81 are precisely fitted together through the fitting body 87, thereby reducing the volatilization of heat along the pipe.
