Description

Technical Field

[0001] The invention belongs to the technical field of connection equipment, and in particular relates to a device for connecting a titanium steel chimney sampling tube and a CEMS measuring point. Background Art

[0002] Electricity is usually generated in large-scale power generation facilities. In power plants, electricity is mainly generated by thermal power generation methods that burn fuel, nuclear power generation methods that use nuclear energy, and hydroelectric power generation methods that use fluid drop. Other power generation facilities also use power generation methods that use solar energy, tidal energy, wind energy, etc.

[0003] Among them, thermal power generation is a very active power generation method that is still in use today. It is a method of driving the turbine by burning fuel. In order to obtain electricity through thermal power generation, fuel must be consumed continuously. The fuel burns in the gas turbine and produces a large amount of exhaust gas (exhaust gas). These exhaust gases contain pollutants produced by the combustion reaction of the fuel and the high-temperature thermal reaction, etc., which require special treatment. After the exhaust gas is treated, it is discharged through the chimney. Due to the strict requirements of the national environmental protection policy, sampling holes need to be opened on the built titanium steel chimney, and the flue gas passing through the chimney is tested to find out whether it meets the corresponding standards. However, most chimneys adopt the standard of imported foreign countries, so that the standard of the sampling points opened on the chimney does not match the standard of the connecting flange opening of the domestic detection equipment. This makes it difficult for the corresponding flange of the sampling pipeline of the detection equipment to be connected with the flange of the original foreign measurement point sampling tube, so that the corresponding connecting flange needs to be re-made for installation during the installation process, which is very inconvenient to use.

[0045] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0046] In order to better understand the purpose, structure and function of the present invention, the following Figure 1-4 , the present invention is further described in detail.

[0047] According to some embodiments of the present application, the invention includes:

[0048] The main body component 1 is provided with an external component 2 (sampling pipe); the external component 2 has a first flow cavity 201 inside; the main body component 1 is a gas exhaust channel, on which is provided a sampling pipe for outward discharge, which can be a chimney structure for a thermal power plant or a smoke exhaust duct in other scenarios.

[0049] A receiving component 3, wherein one end of the receiving component 3 is provided with a first connecting component 301, and the other end is provided with a second connecting component 302, and a second flow cavity 3001 is provided inside the receiving component 3; the first connecting component 301 is connected to the external component 2; the second connecting component 302 is connected to the external device; the first flow cavity 201 and the second flow cavity 3001 are connected to each other;

[0050] The receiving component 3 is a hollow pipe structure, and its cross-sectional shape is selected according to actual needs;

[0051] The first connecting component 301 and the second connecting component 302 are both flange structures. It should be noted that the flange standard of the first connecting component 301 is the same as the flange standard at the opening of the external component 2; the flange standard of the second connecting component 302 is the same as the flange standard of the connection end of the external device.

[0052] The first connecting component 301, the second connecting component 302 and the receiving component 3 can be an integrated structure or a split structure. When it is a split structure, the first connecting component 301, the second connecting component 302 and the receiving component 3 are connected and fixed by bolts, welding, riveting, etc., so that the first connecting component 301, the second connecting component 302 and the receiving component 3 maintain a constant position.

[0053] It should be further explained that sealing components, such as rubber gaskets and other structures, are also provided between the first connecting component 301, the second connecting component 302 and the external component 2 and the external device, which are not limited here, to ensure that the first connecting component 301, the second connecting component 302 and the external component 2 and the external device are in a sealed connection relationship.

[0054] Through the above technical solution, the technical effects produced in the embodiments of the present application are:

[0055] Before use, the external component 2 is blocked by a blind plate, and a hole is made on the first connecting component 301 by making the first connecting component 301 correspond to the blind plate and installing a structure connecting the external component and the blind plate. The first connecting component 301 after the hole is opened is connected to the receiving component 3 through a corresponding connecting piece. During the installation process, the blind plate is removed, and the first connecting component 301 is connected to the opening of the external component 2 so that the first flow chamber 201 and the second flow chamber 3001 are connected. When sampling, the gas in the second flow chamber 3001 is extracted and sampled by the external device by connecting the second connecting component 302 to the sampling end of the external device. After sampling, the receiving component 3 can be removed again or the blind plate can be blocked on the second connecting component 302. It is not only more convenient to use, but can also be installed according to different types of connecting flanges, and the production cost is low.

[0056] The above embodiment is adopted in the embodiment of the present application, wherein it further comprises: a blocking component 4, wherein the blocking component 4 is arranged on the receiving component 3;

[0057] The blocking component 4 comprises:

[0058] The shell component 401 has a third connecting cavity 4001 disposed therein; the shell component 401 is a hollow tubular structure;

[0059] The third connecting component 5 is symmetrically arranged at both ends of the shell component 401, and is connected to the receiving component 3; the third connecting component 5 is a flange structure or a structure that can play a connecting role, so that the shell component 401 is connected to the receiving component 3 through the third connecting component 5, which is not limited here. It should be noted that in order to ensure the sealing during the connection process, a sealing component, such as a rubber gasket, is also provided between the third connecting component 5 and the receiving component 3.

[0060] The valve component 6 is arranged in the housing component 401; the third connecting cavity is closed by the valve component 6.

[0061] It should be noted that the valve component 6 is a combined structure, including:

[0062] A support component 601, the support component 601 is arranged on the shell component 401, and a sliding cavity 6011 is arranged inside the support component 601; the support component 601 is a hollow box structure, and the sliding cavity 6011 penetrates the shell component 401 to the third flow cavity 401; a limiting groove is also arranged at the bottom of the third flow cavity 401 corresponding to the position of the sliding cavity 6011;

[0063] The closing component 602 is arranged in the sliding cavity 6011, and a piston component 603 is arranged on the top thereof; the closing component 602 is a plate-like structure, and its shape is the same as the cross-section of the third circulation cavity 401. The piston component 603 and the sliding cavity 6011 are slidably connected, and the piston component 603 is a plate-like structure, and its shape is the same as that of the sliding cavity 6011; in order to prevent the closing component 602 from rotating, protruding blocks are also arranged on both sides of the piston component 603, and limiting grooves are arranged on both sides of the sliding cavity 6011, and the protruding blocks of the piston component 603 are embedded in the limiting grooves. Through the combined action of the limiting grooves and the protruding blocks, the piston component 603 is rotated, and then the closing component 602 can only be kept in a state of longitudinal movement.

[0064] The stroke component 605 has one end connected to the closing component 602, and the other end passes through the supporting component 601 and is connected to the output end of the driving component 604. The stroke component 605 is a rod-shaped structure, which is driven by the driving component 604 to move the stroke component 605 longitudinally, thereby causing the closing component 602 to move longitudinally in the third flow chamber 401, thereby performing opening and closing operations.

[0065] The driving component 604 is disposed on the supporting component 601 . The driving component 604 may be a telescopic or manual structure.

[0066] When the driving component 604 is a telescopic structure, it includes:

[0067] The telescopic component is a telescopic cylinder, which is provided with a top of a supporting component 601, and a telescopic end thereof is connected to a stroke component 605. The telescopic component drives the stroke component 605 to move longitudinally, thereby driving the closing component 602 to complete the opening and closing operations.

[0068] When the driving component 604 is a rotary structure, it includes:

[0069] The rotating component is arranged on the top of the supporting component 601, and is slidably connected to the supporting component 601. A threaded component is arranged at the center of the rotating component, that is, the rotating component is a handwheel structure, and a threaded hole is arranged at the center of the rotating component, so that the rotating component can rotate on the supporting component 601;

[0070] A stroke component 605, one end of which is connected to the closing component 602, and the other end passes through the supporting component 601 and is connected to the threaded component at the center of the rotating component; a blocking piece is provided on the end of the stroke component 605 that passes through the supporting component 601, that is, the threaded component and the stroke component 605 are linked by the rotation of the rotating component, so that the stroke component 605 moves longitudinally during the rotation of the rotating component, and then the closing component 602 is controlled to be opened and closed by rotating the rotating component forward or reversely.

[0071] In order to further optimize the present technical solution, a quantitative device can be added to control the output of the driving component 604 by setting the quantitative device, thereby controlling the longitudinal displacement of the closing component 602, so as to achieve the technical effect of controlling the size of the opening cross-section of the third flow cavity 401, thereby changing the size of the gas output. The quantitative device can adopt a single-chip microcomputer with automated digital programming or a mechanical periodic rotation structure. Since the quantitative device has been involved in the relevant field, it will not be repeated here.

[0072] Through the above technical solution, the technical effects produced in the embodiments of the present application are:

[0073] The driving component 604 drives the stroke component 605 to move longitudinally, thereby driving the closing component 602 to move longitudinally in the third circulation chamber 401, so as to control the opening cross-section of the third circulation chamber 401 and complete the opening and closing operations, which is beneficial to the connection of external devices and the installation and disassembly of individual components, avoiding the influence of smoke during the installation or disassembly process to cause safety problems, not only making the overall structure more stable, but also making the operation more convenient and the safety performance better.

[0074] The above technical solution is adopted in the embodiment of the present application, wherein the receiving component 3 and the inner wall of the shell component 401 are provided with anti-corrosion components, wherein the anti-corrosion components adopt one of chemical anti-corrosion or physical anti-corrosion.

[0075] When chemical anti-corrosion is used for the anti-corrosion components, the material of the receiving component 3 and the shell component 401 is changed, and a highly corrosion-resistant material is used for production, such as carbon fiber, copper oxide, polytetrafluoroethylene, platinum, synthetic metal, synthetic non-metal, etc. Since the flue gas has a certain temperature, it is preferably made of a high-temperature resistant material.

[0076] When the anti-corrosion components are physically anti-corroded, that is, the receiving component 3 and the shell component 401 are coated with a corrosion-resistant layer, paint, glass flakes, or electroplating, hot-dip plating, spraying and other methods, a layer of metal that is not easily corroded, such as zinc, tin, chromium, nickel, etc., is plated on the inner surface of the receiving component 3 and the shell component 401. These metals often form a dense oxide film due to oxidation, thereby preventing water and air from corroding the receiving component 3 and the shell component 401.

[0077] It is indispensable that the two anti-corrosion methods can be used in combination. The specific choice should be made according to actual needs and actual conditions, so I will not go into details here.

[0078] Through the above technical solution, the technical effects produced in the embodiments of the present application are:

[0079] By providing anti-corrosion components in the receiving component 3 and the shell component 401, the service life of the receiving component 3 and the shell component 401 is improved, the damage of each flow cavity due to the influence of smoke is avoided, and the stability of the overall device is further improved.
