Description

Technical Field

[0001] This utility model relates to the field of pipeline water sampling technology, specifically a sampling device for circulating water quality in a municipal solid waste incineration power plant. Background Technology

[0002] The circulating water system of a municipal solid waste incineration power plant is one of the key systems to ensure the stable operation of the power plant. It provides cooling medium for multiple water systems such as steam turbine condenser and cooling water. The quality of the circulating water directly affects the operating efficiency and service life of these water systems. Therefore, sampling and testing the circulating water quality is a very important part of the daily operation of the power plant.

[0003] However, in the existing circulating water sampling process, the connection and disassembly of the sample storage components and pipelines are quite cumbersome. The assembly of components before each sampling and the disassembly after sampling require a lot of time, which is not conducive to completing the sampling operation quickly and efficiently. This inconvenience is even more prominent when batch sampling is required, which seriously affects the timeliness of water quality testing and the efficiency of operation and maintenance.

[0004] To address this issue, a sampling device for circulating water quality in municipal solid waste incineration power plants is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a sampling device for circulating water quality in municipal solid waste incineration power plants, which has the advantages of convenient disassembly and assembly and high sampling efficiency, and solves the problems of cumbersome disassembly and assembly steps and low sampling efficiency in existing circulating water quality sampling.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for circulating water in a municipal solid waste incineration power plant, comprising a connecting mechanism and a sampling mechanism. The connecting mechanism includes a three-way pipe, with connecting flanges installed at both ends of the three-way pipe and a first mounting flange installed at the top end of the three-way pipe. The sampling mechanism includes a second mounting flange, which is fitted to the first mounting flange. A ball valve is installed on the second mounting flange via a connecting pipe, and a connector for connecting a sample storage component is installed on the ball valve. The sample storage component includes a sample storage bottle.

[0007] Preferably, the connector is a bent pipe, which is installed on the ball valve and has a connecting structure for connecting the sample storage bottle.

[0008] In the design, the bend facilitates the transition between the ball valve and the sample bottle, providing a reasonable flow path for circulating water to flow from the ball valve to the sample bottle, while ensuring smooth water flow and preventing splashing during sampling. In addition, the connection structure on the bend provides a suitable foundation for the installation of the sample bottle, ensuring the compatibility between the sample storage component and the pipeline connection.

[0009] Preferably, the connection structure includes a first clamping connector and a quick-release flange. The first clamping connector is located at the end of the bend, and the quick-release flange is installed on the bend through the first clamping connector. The sample bottle is installed on the quick-release flange.

[0010] In the design, the connection structure consisting of the first clamp connector and the quick-release flange enables the rapid assembly and disassembly of the bend and the sample bottle, which simplifies the disassembly and assembly steps between the sample bottle and the pipeline, and reduces the time for component operations before and after sampling. The positioning fit of the first clamp connector and the convenient disassembly and assembly of the quick-release flange can also improve the efficiency of batch sampling while ensuring connection stability.

[0011] Preferably, the top of the sample bottle is provided with a second locking connector, which is installed in conjunction with the first locking connector.

[0012] In the design, the second clamp at the top of the sample bottle achieves precise docking with the first clamp at the end of the bend, which enhances the positioning accuracy when the sample bottle is connected to the bend and prevents water leakage or sampling problems caused by misalignment.

[0013] Preferably, the second snap-fit ​​connector is provided with a third sealing ring.

[0014] In the design, the third sealing ring on the second connector seals the gap between the second connector and the first connector, preventing leakage of circulating water at the connection between the sample bottle and the bend, ensuring a clean sampling environment while avoiding sample loss.

[0015] Preferably, a first sealing ring is provided on the first mounting flange.

[0016] In the design, the first sealing ring on the first mounting flange achieves the sealing of the connection between the connecting mechanism and the sampling mechanism. It has the characteristic of filling the micro gaps between the first mounting flange and the second mounting flange, which can prevent circulating water from leaking from the connection between the two flanges. At the same time, the setting of the first sealing ring can also improve the overall sealing performance of the connecting mechanism and ensure the reliability of the connection between the sampling device and the circulating water system.

[0017] Preferably, a second sealing ring is provided on the second mounting flange.

[0018] In the design, the second sealing ring on the second mounting flange achieves a double sealing fit with the first sealing ring on the first mounting flange, which has the characteristic of superimposing and enhancing the sealing performance of the connection between the two flanges, and can further reduce the risk of circulating water leakage; at the same time, the synergistic effect of the second sealing ring and the first sealing ring can also maintain the stability of the sealing effect during long-term use and extend the service life of the sealing components of the device.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model achieves convenient assembly and disassembly and efficient sampling by setting up a connecting mechanism, a tee pipe, a connecting flange, a first mounting flange, a sampling mechanism, a second mounting flange, a connecting pipe, a ball valve, a connector for connecting the sample storage component, and a sample storage bottle.

[0020] The connecting flanges at both ends of the tee pipe can quickly connect the connecting mechanism to the circulating water system of the municipal solid waste incineration power plant without the need for complex modifications to the original system, thus reducing the operational difficulty of overall installation and disassembly of the device. The matching installation method of the first mounting flange and the second mounting flange allows the connecting mechanism and the sampling mechanism to be directly connected or separated, eliminating the cumbersome steps of multiple sets of pipelines being wound and connected in traditional sampling devices. The ball valve is installed on the second mounting flange through a connecting pipe. During sampling, only the ball valve needs to be operated to control the flow of circulating water, eliminating the need for frequent disassembly and assembly of the sampling mechanism and the connecting mechanism, thus shortening the sampling preparation time. The connector used to connect the sample storage components can quickly connect the sample storage bottle to the ball valve. After sampling, the sample storage bottle can be directly removed for testing. At the same time, it is easy to replace the sample storage bottle for the next sampling, which effectively solves the problem of cumbersome disassembly and assembly steps and low sampling efficiency in the existing circulating water quality sampling.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] like Figures 1 to 6 As shown, one embodiment of this utility model is provided: a sampling device for circulating water quality in a municipal solid waste incineration power plant, including a connecting mechanism 1, on which a sampling mechanism 2 is installed. The connecting mechanism 1 and the sampling mechanism 2 are detachably connected by a flange, which facilitates the overall maintenance and component replacement of the device.

[0025] The connecting mechanism 1 includes a three-way pipe 11, which is made of corrosion-resistant and high-temperature-resistant material to adapt to the complex working conditions that may exist in the circulating water of the municipal solid waste incineration power plant and to avoid damage due to water quality during long-term use. Both ends of the tee pipe 11 are equipped with connecting flanges 12. The connecting flanges 12 are fixed to the two ends of the tee pipe 11 by welding. The connecting flanges 12 are connected to the corresponding flanges of the circulating water system pipeline through conventional fastening components to achieve stable connection between the tee pipe 11 and the circulating water system. When disassembling later, only the fastening components need to be operated to separate the pipes without any destructive modification to the original circulating water system pipeline. The top end of the tee pipe 11 is equipped with a first mounting flange 13. The first mounting flange 13 is fixed to the top end of the tee pipe 11 by welding. The side of the first mounting flange 13 facing the sampling mechanism 2 is provided with a first sealing ring 131. The first sealing ring 131 is made of an aging-resistant and water-corrosion-resistant material to ensure that when the first mounting flange 13 is in contact with the sampling mechanism 2, the first sealing ring 131 can fully play its sealing role and prevent circulating water from leaking from the first mounting flange 13.

[0026] The sampling mechanism 2 includes a second mounting flange 21, the structural dimensions of which are completely matched with the first mounting flange 13. It is fixed to the first mounting flange 13 by conventional fastening components, thereby realizing the detachable connection between the sampling mechanism 2 and the communication mechanism 1. The disassembly and assembly process only requires conventional tools and is easy to operate. The second mounting flange 21 is also provided with a second sealing ring 211 on the side facing the first mounting flange 13. The material of the second sealing ring 211 is compatible with the first sealing ring 131. The second sealing ring 211 and the first sealing ring 131 cooperate to form a double sealing structure, which further improves the sealing performance when the second mounting flange 21 is connected to the first mounting flange 13. Even if a single sealing ring is slightly worn after long-term use, the sealing effect can still be maintained by the other sealing ring, reducing the risk of leakage. The second mounting flange 21 is provided with a connecting pipe 212. One end of the connecting pipe 212 is connected to the second mounting flange 21 by welding, and the other end of the connecting pipe 212 is sealed to the water inlet of the ball valve 22. The ball valve 22 is a flexible and wear-resistant type. The operator can control the sampling on and off by controlling the opening and closing state of the ball valve 22, without having to frequently disassemble and assemble the sampling mechanism 2 and the connecting mechanism 1, thus simplifying the sampling operation steps. The outlet end of the ball valve 22 is sealed to one end of the elbow 23. The elbow 23 can change the flow direction of the circulating water to avoid splashing caused by direct water flow during sampling, and at the same time adapt to the installation requirements of the sample storage bottle 25. The other end of the bend 23 is provided with a first clamping connector 231. The first clamping connector 231 is connected to the bend 23 by welding. A quick-release flange 24 is installed on the bend 23 through the first clamping connector 231. The quick-release flange 24 has the characteristic of easy disassembly and assembly, and achieves a stable connection through cooperation with the first clamping connector 231. A sample storage bottle 25 is installed on the bend 23 via a quick-release flange 24. The sample storage bottle 25 is made of a material that facilitates observation of the internal sample. The bottle body is marked for observing the sampling amount, making it convenient for operators to control the sampling volume. The top of the sample bottle 25 is provided with a second clamping connector 251, which is integrally formed with the sample bottle 25. The structure of the second clamping connector 251 is adapted to the first clamping connector 231. The connection between the bent tube 23 and the sample bottle 25 is realized by cooperating with the first clamping connector 231. With the quick-release flange 24, the assembly and disassembly of the sample bottle 25 can be completed quickly. Furthermore, the second connector 251 is also equipped with a third sealing ring 252. The third sealing ring 252 is made of a chemically resistant material to ensure that when the second connector 251 is connected to the first connector 231, the third sealing ring 252 can fill the gap between the two, ensuring the sealing performance when the sample bottle 25 is connected to the bent tube 23, and preventing leakage of circulating water or contamination of the sample by external impurities.

[0027] When using this utility model, the connecting flanges 12 at both ends of the tee pipe 11 are aligned with the corresponding flanges of the circulating water system pipeline of the municipal solid waste incineration power plant, and fixed by fastening components to realize the connection between the connecting mechanism 1 and the circulating water system; the second sealing ring 211 is installed in the sealing structure of the second mounting flange 21, the second mounting flange 21 is aligned with the first mounting flange 13, and fixed by fastening components to realize the assembly of the sampling mechanism 2 and the connecting mechanism 1; Install the third sealing ring 252 on the second clamping connector 251 at the top of the sample bottle 25, align the second clamping connector 251 with the first clamping connector 231 of the bend 23, and fix it through the quick-release flange 24 to realize the installation of the sample bottle 25. Control the ball valve 22 to the open state. At this time, the circulating water in the three-way pipe 11 flows through the connecting pipe 212, the ball valve 22 and the bend 23 in sequence and then flows into the sample storage bottle 25. The operator observes the sampling amount through the marking on the sample storage bottle 25. After the requirement is met, control the ball valve 22 to the closed state. Remove the quick-release flange 24 to release the fixation, take out the sample storage bottle 25 containing the sample and send it for testing; and install a new sample storage bottle 25 according to the sampling preparation steps, and then the next sampling can be carried out.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
