Description

Technical Field

[0001] This invention relates to the field of flue gas sampling technology, specifically to a multi-station flue gas sampling device. Background Technology

[0002] The development of flue gas sampling technology began with the need for industrial emissions and air quality control. With increasingly stringent environmental regulations and growing public concern about environmental issues, flue gas sampling technology has continuously improved to meet the demands for precise measurement and monitoring. Flue gas samplers typically employ the isokinetic sampling principle, using a pitot tube to measure the flue gas velocity and automatically adjusting the sampling flow rate to ensure that the collected sample represents the characteristics of the entire emission stream. This method can accurately determine the emission concentration and total amount of particulate matter (gas), as well as the dust removal and desulfurization efficiency of equipment. However, existing flue gas sampling devices require professionals to climb large chimneys to collect flue gas each time, increasing the operational difficulty for personnel and raising sampling costs due to the need for specialized personnel for each sampling operation.

[0007] As a further technical solution, the sampling component also includes: The worm gear is rotatably mounted on the mounting component and located within the mounting cavity; A worm gear is rotatably mounted on the mounting component and located within the mounting cavity. The worm gear meshes with the worm, and the worm drives the worm gear to rotate. The valve body is rotatably mounted on the mounting component via the worm gear, and the worm gear drives the valve body to rotate.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] Example like Figures 1-5 As shown, this embodiment proposes... A multi-station dust sampling device, comprising: Mounting base 10 is used to be installed on the reserved flue gas collection hole; Mounting component 20 is disposed on mounting base 10. Mounting component 20 has mounting cavity 30 and a plurality of through slots 40, which are spaced apart. There are several sampling components 50, all of which are disposed in the mounting cavity 30 and are connected to the outside through several through slots 40.

[0019] In this embodiment, existing flue gas sampling equipment requires experts to go to the site for sampling each time, which is costly and limited in number. Furthermore, sampling at heights is dangerous. This solution provides a mounting base 10, which is directly placed on the pre-reserved flue gas collection hole of the industrial chimney. The mounting component 20 is installed on the industrial chimney, and multiple sampling components 50 are installed in the internal cavity 30 of the mounting component 20. Each sampling component 50 collects flue gas generated by the chimney through a through-slot 40, and each component samples independently. Sampling can be performed sequentially by multiple sampling components 50 at specified times, thereby reducing the number of times staff need to go to the site for sampling.

[0020] Furthermore, the sampling component 50 includes: Ball valve 51 is installed in the mounting cavity 30; The sampling head module 52 is mounted on the ball valve 51 and located inside the mounting cavity 30. The ball valve 51 is used to control whether the sampling head module 52 is connected to or disconnected from the outside.

[0021] In this embodiment, the sampling component 50 includes a ball valve 51 and a sampling head module 52. Sampling is performed by the sampling head module 52 passing through the through groove 40. The presence of the ball valve 51 can adjust whether the sampling head module 52 is connected to or disconnected from the outside, thereby controlling whether the sampling head module 52 performs sampling and preventing other gases from entering the sample after sampling, which would reduce the sampling accuracy. Furthermore, the sampling head module 52 can be quickly plugged in and unplugged, thereby enabling rapid installation and replacement of the sampling head module.

[0022] Furthermore, the ball valve 51 includes: The valve body 511 is rotatably mounted on the mounting part 20 and located in the mounting cavity 30. The valve body 511 has an air inlet 512. The sampling head module 52 is mounted on the valve body 511. After the valve body 511 rotates, it is used to drive the sampling head module 52 to rotate out of the through groove 40. The valve core 513 is mounted on the mounting part 20, and the valve core 513 has a through hole 514. After the valve body 511 rotates, the through hole 514 and the air inlet 512 are connected or not connected.

[0023] In this embodiment, the solution includes a valve body 511 and a valve core 513. The valve body 511 is rotatably mounted on the mounting part 20, while the valve core 513 is fixedly mounted on the mounting part 20. The valve core 513 has a through hole 514, and the valve body 511 has an air inlet 512. When the valve body 511 rotates, it is possible to adjust whether the through hole 514 of the valve core 513 and the air inlet 512 of the valve body 511 are connected. Moreover, the ball valve 51 has high precision and can more efficiently isolate the sampling container from the outside world.

[0024] Furthermore, the sampling component 50 also includes: The worm gear 53 is rotatably mounted on the mounting component 20 and located within the mounting cavity 30; The worm gear 54 is rotatably mounted on the mounting part 20 and located in the mounting cavity 30. The worm gear 54 meshes with the worm 53, and the worm 53 is used to drive the worm gear 54 to rotate. The valve body 511 is rotatably mounted on the mounting part 20 through the worm gear 54, and the worm gear 54 is used to drive the valve body 511 to rotate. The drive shaft has one end mounted on the worm gear 53 and the other end used to connect to the drive unit.

[0025] In this embodiment, the solution includes a worm gear 54 and a worm 53. The worm 53 is rotatably mounted on the mounting part 20. The worm gear 54 and the worm 53 mesh, which can change the direction of torque. The worm 53 is driven to rotate through the transmission shaft, and the worm 53 drives the worm gear 54 to rotate. The worm gear 54 can then drive the valve body 511 to rotate, thereby allowing the sampling head module 52 to rotate out of the through slot 40 or not. When the sampling head module 52 rotates out of the through slot 40, the ball valve 51 is in the open state; when the sampling head module 52 does not rotate out of the through slot 40, the ball valve 51 is in the closed state.

[0026] Furthermore, it also includes: Sealing assembly 60 is used to seal the mounting cavity 30.

[0027] In this embodiment, since the sampled flue gas contains various impurities and corrosive gases, if the installation cavity 30 is not sealed, the various components inside the installation cavity 30 may be damaged by the corrosive gases, thereby affecting the overall service life of the device.

[0028] Furthermore, the sealing assembly 60 includes: There are several rotating plates 61, each of which is rotatably mounted on the mounting part 20 and located at several through slots 40. The rotating plates 61 are used to open or close the through slots 40.

[0029] In this embodiment, the sealing device is a rotating plate 61, the equipment cavity is square in shape, and the equipment seal is achieved by a flip door opening and closing method. After the rotating plate 61 rotates, the through slot 40 can be opened or closed. When sampling is required, the rotating plate 61 is opened, and when sampling is not required, the rotating plate 61 can be closed, which can maximize the protection of the components in the installation cavity 30.

[0030] Furthermore, the sealing assembly 60 also includes: The hinge rod 62 is hinged at one end to the valve body 511 and at the other end to the rotating plate 61. After the valve body 511 rotates, it is used to drive the rotating plate 61 to rotate.

[0031] In this embodiment, a hinge rod 62 is provided on the valve body 511. When sampling is required, the transmission shaft drives the worm gear 54 and worm 53, thereby driving the valve body 511. After the valve body 511 rotates, the ball valve 51 can be opened. The rotation of the valve body 511 can drive the hinge rod 62 to rotate and open the rotating plate 61. The sampling head module 52 also rotates out of the through groove 40 under the drive of the valve body 511 to perform sampling. After sampling is completed, the transmission shaft drives the valve body 511 to rotate. At the same time, the ball valve 51 closes and the sampling head module 52 resets. The rotating plate 61 resets to complete the sampling. The rotation of the valve body 511 and the opening and closing of the rotating plate 61 share the same power.

[0032] Furthermore, the drive shaft is a flexible shaft 70.

[0033] In this embodiment, since the rotating plate 61 needs to be opened during sampling, corrosive gas will enter the installation cavity 30. In order to increase the service life of this device, the drive shaft is set as a flexible shaft 70, and the drive device is far away from the flue gas, thereby avoiding corrosive damage to the drive device caused by the corrosive flue gas, thus increasing the service life of the drive device.

[0034] Furthermore, the mounting component 20 is slidably disposed on the mounting base 10, and the mounting base 10 has a plurality of limiting blocks 11 inside, and also includes: There are several rollers 80, and the rollers 80 are rotatably disposed on several limit blocks 11, and the rollers 80 are used to abut against the mounting parts 20.

[0035] In this embodiment, in order to facilitate the installation and disassembly of the mounting component and the mounting base 10, a limiting block 11 is provided in the mounting base 10. The limiting block 11 can be locked around the mounting component to prevent the mounting component from shaking after installation. Rollers 80 are provided on the limiting block 11 to reduce the friction force of the mounting component sliding onto the mounting base 10, thereby making the installation of the mounting component and the mounting base 10 faster.

[0036] Furthermore, several through slots 40 are arranged alternately on the mounting component 20.

[0037] In this embodiment, the through slots 40 of this solution are staggered on the mounting component 20, which can increase the number of sampling head modules 52 installed in a limited space, thereby enabling more efficient periodic sampling.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
