Description

Technical Field

[0001] This utility model relates to the field of flue gas sampling technology, specifically a flue gas sampling device for boiler energy efficiency testing. Background Technology

[0002] Energy efficiency testing refers to the measurement and recording of a series of parameters of a boiler under operating conditions in accordance with relevant national laws and regulations, and the calculation of the boiler's thermal efficiency. The results of the energy efficiency test are then judged. The purpose of energy efficiency testing is to strengthen the design, manufacturing, and operation management of boilers, improve the energy efficiency level of boiler operation, and promote the development, manufacturing, and application of new high-efficiency and energy-saving boilers.

[0003] Existing boiler energy efficiency testing flue gas sampling devices pose a risk of burns if staff stand at the boiler's exhaust port or flue during sampling. Additionally, if the boiler flue gas contains other impurities, it can interfere with subsequent test results. Therefore, we propose a new boiler energy efficiency testing flue gas sampling device. Utility Model Content

[0004] The purpose of this invention is to provide a flue gas sampling device for boiler energy efficiency testing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a boiler energy efficiency testing flue gas sampling device, comprising an assembly, a protective component, a wrapping component, and a pipe body. The top of the assembly is provided with a protective component, and the tip of the protective component is provided with a wrapping component. The side of the wrapping component is provided with a pipe body. The protective component includes a connecting pipe, an inner cavity, a locking block, and a mesh plate. The connecting pipe has an inner cavity, the middle of the inner cavity has a locking block, and the side of the locking block has a mesh plate.

[0006] Furthermore, the mesh plate is connected to the connecting pipe via a locking block to form a locking structure, and the mesh plate is detachable.

[0007] Furthermore, the packaging assembly includes a cover, a heat-resistant airbag, a vent, and a heat-resistant fabric. The heat-resistant airbag is located inside the cover, a vent is located on one side of the heat-resistant airbag, and a heat-resistant fabric is located on the other side of the heat-resistant airbag.

[0008] Furthermore, the cover and the heat-resistant airbag enclose the tube body, and the heat-resistant airbag and the heat-resistant cloth are integrated.

[0009] Furthermore, the assembly includes a substrate, a detection body, and a telescopic rod, with the detection body provided on one side of the substrate and the telescopic rod provided on the other side of the substrate.

[0010] Furthermore, the telescopic rod is connected to the protective component, and the protective component and the wrapping component are integrated.

[0011] Furthermore, the pipe body includes a boiler through pipe and a retaining ring, and a retaining ring is provided on one side of the boiler through pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the length of the telescopic rod is adjusted by the height of the boiler pipe and the retaining ring, which facilitates the wrapping and allows the internal flue gas to circulate. The retaining ring of the boiler pipe is provided with heat insulation material on the outside, and the heat-resistant airbag and heat-resistant cloth inside the cover are also provided with heat insulation material. When it is necessary to connect the boiler flue gas, the airbag is squeezed to reduce leakage. Since the connecting pipe is wrapped inside the retaining ring of the boiler pipe through the pointed cover, the internal flue gas will flow through the connecting pipe. The mesh plate in the middle is provided to block the dust in the boiler flue gas, thereby efficiently detecting the energy efficiency of the flue gas.

[0013] The connecting pipe is wrapped inside the retaining ring of the boiler through the pointed cover, allowing the built-in flue gas to flow through the connecting pipe. A mesh plate is set in the middle, which is inserted by the built-in retaining block to complete the installation of the mesh plate and facilitate its replacement later. The mesh plate helps to block dust in the boiler flue gas. By detecting the end of the connecting pipe of the detection body, the energy efficiency of the flue gas can be efficiently detected.

[0014] The outer side of the retaining ring of the boiler pipe is equipped with heat insulation material, while the internal heat-resistant airbag and heat-resistant cloth of the cover are also equipped with heat insulation material. When it is necessary to sample the boiler flue gas, the cover wraps around the retaining ring, and the built-in heat-resistant airbag is inflated to wrap around the retaining ring. The heat-resistant cloth on the side can be used to fit and wrap the retaining ring. The airbag compression reduces leakage and improves the sampling of flue gas at the end of the subsequent device insertion and connection pipe. Then, the bottom detection body performs real-time detection. Attached Figure Description

The protective component 2 is provided at the top of the assembly 1, and the wrapping component 3 is provided at the tip of the protective component 2. The pipe body 4 is provided on the side of the wrapping component 3. The protective component 2 includes a connecting pipe 201, an inner cavity 202, a locking block 203, and a mesh plate 204. The inner cavity 202 is provided inside the connecting pipe 201, and a middle part of the inner cavity 202 is provided with... There is a locking block 203, and a mesh plate 204 is provided on the side of the locking block 203. The mesh plate 204 and the connecting pipe 201 form a locking structure through the locking block 203, and the mesh plate 204 is detachable. The connecting pipe 201 is wrapped in the retaining ring 402 of the boiler through the pointed cover 301, so that the built-in flue gas will flow from the connecting pipe 201. The mesh plate 204 is provided in the middle, and is moved and inserted by the built-in locking block 203 to complete the installation of the mesh plate 204. The replacement of the mesh plate 204 is to facilitate the blocking of dust in the boiler flue gas. The end of the connecting pipe 201 is connected to the detection body 102 to efficiently detect the energy efficiency of the flue gas. The assembly 1 includes a base plate 101, a detection body 102 and a telescopic rod 103. The detection body 102 is provided on one side of the base plate 101 and the telescopic rod 103 is provided on the other side of the base plate 101. The telescopic rod 103 is connected to the protective component 2 and the protective component 2 and the wrapping component 3 are integrated. The base plate 101 is used to place the flue gas detection body 102, while the telescopic rod 103 is used to support the connecting pipe 201 and the cover 301. The length of the telescopic rod 103 is adjusted according to the height of the boiler through pipe 401 and the retaining ring 402 to align the two and facilitate the wrapping to allow the internal flue gas to flow. The pipe body 4 includes the boiler through pipe 401 and the retaining ring 402, and the retaining ring 402 is provided on one side of the boiler through pipe 401.

[0020] like Figure 3As shown, a boiler energy efficiency testing flue gas sampling device includes a casing 301, a heat-resistant airbag 302, a vent 303, and a heat-resistant cloth 304. The heat-resistant airbag 302 is located inside the casing 301. A vent 303 is located on one side of the heat-resistant airbag 302, and the heat-resistant cloth 304 is located on the other side. The casing 301 and the heat-resistant airbag 302 enclose the pipe body 401, and the heat-resistant airbag 302 and the heat-resistant cloth 304 are integrally formed. The retaining ring 402 of the boiler through pipe 401 is located on the outside. The cover 301 is equipped with heat-insulating material, and the internal heat-resistant airbag 302 and heat-resistant cloth 304 are also equipped with heat-insulating material. When it is necessary to sample the boiler flue gas, the cover 301 wraps around the retaining ring 402, and the internal heat-resistant airbag 302 is inflated to wrap around the retaining ring 402. The heat-resistant cloth 304 on the side can be used to fit and wrap the retaining ring 402. The airbag compression reduces leakage and improves the sampling of flue gas at the end of the subsequent device insertion connecting pipe 201. Then, the bottom detection body 102 performs real-time detection.

[0021] Working principle: First, the base plate 101 is used to place the flue gas detection body 102, while the telescopic rod 103 is used to support the connecting pipe 201 and the cover 301. The length of the telescopic rod 103 is adjusted according to the height of the boiler pipe 401 and the retaining ring 402, and the two are aligned with each other to facilitate the wrapping and allow the internal flue gas to circulate.

[0022] The outer side of the retaining ring 402 of the boiler pipe 401 is provided with heat insulation material, and the heat-resistant airbag 302 and heat-resistant cloth 304 inside the cover 301 are also provided with heat insulation material. When it is necessary to connect the boiler flue gas, the cover 301 wraps the retaining ring 402, and the built-in heat-resistant airbag 302 is inflated to wrap the retaining ring 402. The heat-resistant cloth 304 on the side can be used to fit and wrap the retaining ring 402. The airbag compression reduces leakage. The subsequent device inserts the connecting pipe 201 to the end to sample the flue gas, and then the bottom detection body 102 performs real-time detection.

[0023] Because the connecting pipe 201 is wrapped inside the retaining ring 402 of the boiler pipe 401 by the tip cover 301, the built-in flue gas will flow through the connecting pipe 201. The middle is provided with a mesh plate 204, which is inserted by the built-in retaining block 203. Its function is to block the dust in the boiler flue gas. By connecting the end of the connecting pipe 201 to the detection body 102, the flue gas can be efficiently detected.
