Description

Technical Field

[0001] This utility model relates to the field of boiler technology, and more specifically, to a boiler sampling cooler. Background Technology

[0002] A boiler is an energy conversion device, mainly composed of a boiler and a furnace. During long-term use, as water evaporates continuously, the total alkalinity remaining in the boiler water can exceed 26 mmol / L, causing severe alkaline corrosion. Therefore, in the operation of steam boilers, it is necessary to regularly sample and test the boiler water to control the alkali concentration. However, when sampling boiler water, it is often necessary to cool the boiler water through a cooler before testing. For example, a boiler sampling cooler proposed in application number "CN202123179542.4" addresses the inconvenience of disassembly and assembly and insufficient cleaning of the cooling tank. To address the issue of cleanliness, the following solution is proposed: a support frame is included, a cooling tank is installed on the inner wall of the support frame, a disc-shaped cap is provided at the top of the cooling tank, and a sampling tube is provided on the inner wall of the cooling tank. Both ends of the sampling tube penetrate the top of the disc-shaped cap, and the two ends of the sampling tube are respectively set as a sampling inlet and a sampling outlet. In this invention, by providing an opening at the bottom of the cooling tank and sealing it with a base, cleaning the cooling tank only requires disassembling the base, without needing to disassemble the connecting parts at the top of the equipment, making operation more convenient. Furthermore, most of the dirt is deposited on the base, making cleaning more thorough. A limiting component limits the installation of the mounting plate and the base, making the base easy and effortless to assemble and disassemble.

[0003] However, although the above technical solutions can clean the inside of the cooling tank and prevent dirt from accumulating inside, the boiler water is cooled through the same sampling tube for each test, resulting in residual boiler water on the inner wall of the sampling tube. This residual boiler water mixes with the boiler water in the next test, causing the test results to deviate from those inside the boiler. Therefore, we propose a boiler sampling cooler to solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a boiler sampling cooler, which solves the problem that although the inside of the cooling tank can be cleaned to prevent dirt from accumulating inside, the boiler water is cooled through the same sampling tube for each test, resulting in the boiler water that was cooled down previously remaining on the inner wall of the sampling tube. This residual boiler water will mix with the boiler water in the next test, thus causing the test results to deviate from those inside the boiler.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A boiler sampling cooler includes a housing with a curved pipe installed inside. A water inlet pipe is installed through the upper end of the housing and connected to the upper end of the curved pipe. A water outlet pipe is installed through one side of the housing and connected to the lower end of the curved pipe. A main pipe is installed on the side of the housing away from the water outlet pipe. A liquid inlet pipe is installed between the main pipe and the housing. A drain pipe is installed through the lower end of the housing near the water outlet pipe. A cleaning mechanism is installed between the housing, the water inlet pipe, and the water outlet pipe. A valve No. 1 is installed at the upper end of the water inlet pipe, and a valve No. 5 is installed at one end of the water outlet pipe.

[0007] Preferably, the cleaning mechanism includes a water guide pipe, which is installed between the main pipe and the inlet pipe, and a second valve is installed inside the water guide pipe.

[0008] Preferably, a No. 2 connecting pipe is installed between the water outlet pipe and the drain pipe, and a No. 4 valve is installed inside the No. 2 connecting pipe.

[0009] Preferably, a hot air blower is installed at the upper end of the housing, and an air inlet pipe is installed between the hot air blower and the water inlet pipe. A valve No. 3 is installed inside the air inlet pipe.

[0010] Preferably, a filter box is installed at one end of the upper surface of the housing, and a connecting pipe No. 1 is installed through the lower end of the filter box and the hot air blower.

[0011] Preferably, the upper part of the filter box is equipped with several filter layers, the upper part of the filter box is equipped with a sealing cover, and the upper part of the filter box is provided with several air inlets.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) In this utility model, after the sampled water is cooled and discharged by the bend, the user can open valves No. 2 and No. 4 and close valves No. 1 and No. 5, so that the liquid inside the main pipe can be flushed and cleaned by the water guide pipe into the inlet pipe and the bend, so as to avoid the boiler water remaining inside the bend. Then the liquid after flushing can be discharged through the No. 2 connecting pipe into the drain pipe. Then the user closes valve No. 2 and opens valve No. 3, so that hot air can be dried by the air inlet pipe into the bend, keeping the inside of the bend dry and avoiding the mixing of boiler water, which would cause inaccurate measurement data.

[0014] (2) In this utility model, the dust and impurities in the air are filtered by the filter layer, thereby preventing these dust and impurities from entering the inside of the bend through the hot air and causing pollution, improving the cleanliness of the inside of the bend, and also improving the dryness of the inside of the bend, thus improving the accuracy of the boiler water test data each time.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1 to 4As shown in the figure, this utility model embodiment proposes a boiler sampling cooler, including a box body 1. A bent pipe 9 is installed inside the box body 1. A water inlet pipe 2 is installed through the upper end of the box body 1 and is connected to the upper end of the bent pipe 9. A water outlet pipe 7 is installed through one side of the box body 1 and is connected to the lower end of the bent pipe 9. A main pipe 4 is installed on the side of the box body 1 away from the water outlet pipe 7. A liquid inlet pipe 10 is installed through the main pipe 4 and the box body 1. A drain pipe 6 is installed through the lower end of the side of the box body 1 near the water outlet pipe 7. A cleaning mechanism 5 is installed between the box body 1, the water inlet pipe 2 and the water outlet pipe 7. A valve 3 is installed at the upper end of the water inlet pipe 2 and a valve 8 is installed at one end of the water outlet pipe 7.

[0022] like Figure 4 As shown, in another embodiment of this utility model, the cleaning mechanism 5 includes a water guide pipe 501, which is installed between the main pipe 4 and the inlet pipe 2. A second valve 502 is installed inside the water guide pipe 501. A second connecting pipe 511 is installed between the outlet pipe 7 and the drain pipe 6. A fourth valve 512 is installed inside the second connecting pipe 511. A hot air blower 505 is installed at the upper end of the housing 1. An air inlet pipe 503 is installed between the hot air blower 505 and the inlet pipe 2. A third valve 504 is installed inside the air inlet pipe 503. A filter box 506 is installed at one end of the upper surface of the housing 1. A first connecting pipe 507 is installed between the lower end of the filter box 506 and the hot air blower 505. Several filter layers 508 are installed at the upper end of the filter box 506. A sealing cover 510 is installed at the upper end of the filter box 506. Several air inlets 509 are provided at the upper end of the filter box 506.

[0023] The user injects the extracted boiler water sample into the bend 9 through the inlet pipe 2. Simultaneously, external liquid flows along the main pipe 4, allowing it to enter the tank 1 through the liquid inlet pipe 10. This allows the liquid to contact the bend 9, carrying away heat from the bend 9 and the sample inside. The cooled sample is then discharged through the outlet pipe 7, while the liquid inside the tank 1 is discharged through the drain pipe 6. After the sample has cooled and been discharged, the user closes valves 1 (3) and 5 (8) to seal the inlet pipe 2, bend 9, and outlet pipe 7. Then, the user opens valves 2 (502) and 4 (512) to allow liquid from the main pipe 4 to flow through the guide pipe 501 into the inlet pipe 2, flushing the inside of the bend 9. The flushed liquid then flows through the connecting pipe 2 (511) into the drain pipe 6, preventing boiler water from remaining in the bend. After the boiler water flushing is completed, the user can close valve 2 502 and open valve 3 504 to connect air inlet pipe 503 and water inlet pipe 2. Then, the user can start hot air blower 505 to draw air into the filter box 506 through connecting pipe 1 507. The air enters the filter box 506 through air inlet 509 and is then filtered by filter layer 508 before entering the hot air blower 505 through connecting pipe 1 507 for heating. Finally, the heated high-temperature air enters the water inlet pipe 2 and the inside of bend pipe 9 through air inlet pipe 503 to dry the inside of bend pipe 9. At the same time, the gas can be discharged through connecting pipe 2 511 and drain pipe 6 to ensure that the inside of bend pipe 9 is cleaner and to prevent boiler water from remaining inside bend pipe 9 and mixing with the next boiler water sample, thus improving the accuracy of each filtered water sampling inspection.

[0024] The working principle of this boiler sampling cooler:

[0025] In use, the user first injects the boiler water sample into the bend 9 through the inlet pipe 2. Simultaneously, external liquid flows along the main pipe 4, allowing it to enter the tank 1 through the liquid inlet pipe 10. This allows the liquid to contact the bend 9, carrying away heat from the bend 9 and the sample inside. The cooled sample is then discharged through the outlet pipe 7, while the liquid inside the tank 1 is discharged through the drain pipe 6. After the sample has cooled and been discharged, the user closes valves 3 and 8 to seal the inlet pipe 2, bend 9, and outlet pipe 7. Then, the user opens valves 502 and 512, allowing liquid from the main pipe 4 to flow through the guide pipe 501 into the inlet pipe 2, flushing the inside of the bend 9. The flushed liquid then flows through the connecting pipe 511 into the drain pipe 6 for discharge, preventing further stagnation of the boiler water. The water remains inside the bend 9. After the boiler water flushing is completed, the user can close valve 2 502 and open valve 3 504 to connect the air inlet pipe 503 and the water inlet pipe 2. Then, the user can start the hot air blower 505, which draws air into the filter box 506 through the first connecting pipe 507. The air enters the filter box 506 through the air inlet 509 and is then filtered by the filter layer 508 before entering the hot air blower 505 through the first connecting pipe 507 for heating. Finally, the heated high-temperature air enters the water inlet pipe 2 and the bend 9 through the air inlet pipe 503 to dry the inside of the bend 9. At the same time, the gas is discharged through the second connecting pipe 511 and the drain pipe 6, ensuring that the inside of the bend 9 is cleaner and preventing the boiler water from remaining inside the bend 9 and mixing with the next boiler water sample, thus improving the accuracy of each filtered water sampling inspection.

[0026] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
