Description

Technical Field

[0001] The present invention relates to the field of flue gas condensate sampling, in particular to a flue gas condensate sampling device for a generator set. Background Art

[0002] The flue gas discharged from the boiler of a gas-fired power plant contains a large amount of heat. In the current production, we will recycle the heat in the flue gas. During the recovery process, the temperature of the flue gas will decrease, and condensed water will be produced. These condensed waters will be used as water sources such as heating network, circulating water, and boiler feed water. At this time, we need to understand the water quality of the condensed water, and need to test its pH value, total nitrogen, ammonia nitrogen, total phosphorus, COD, alkalinity, hardness and other sample indicators to determine the flue gas condensate treatment process and recycling direction, so as to achieve the purpose of accurate and reasonable utilization of condensate resources and realize the goal of energy conservation and carbon reduction. Therefore, we need to sample the flue gas discharged from the boiler. There are already devices for sampling flue gas in the prior art, such as the prior art CN222461092U, a new type of flue gas condensate sampling device, which is provided with a condenser to actively cool the flue gas to generate cooling water, and then The cooling water is sampled to facilitate subsequent testing. However, the device is only designed with one sampling pipe and can only take one sample at a time. However, when we perform component analysis on the condensed water, we need multiple samples to verify consistency. If the device is used for sampling and multiple samples are taken at a time, the condensed water will contaminate the sampling pipe, and the impurity content in the condensed water taken later will inevitably be greater than the condensed water taken earlier, which will affect the test results. Moreover, the device needs to drain the ice water after the ice melts and then replace the ice. The ice cannot be replaced conveniently, and the time for replacing the ice is too long, which will also affect the sampling of the condensed water. If the ice melts completely and the condensation temperature is not low enough, a large amount of flue gas cannot be condensed in time and passes into the sampling container, and comes into contact with the condensed water in the sampling container. Impurities will dissolve into the condensed water that has been obtained, resulting in errors in the test.

[0003] Based on the problems in the above existing technologies, we need a more complete sampling device that is convenient for multiple sampling and reduces the impact of cooling water contamination of the condensation pipe. It also needs to be able to quickly replace ice cubes to ensure sampling quality. Summary of the Invention

[0025] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0026] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0027] Reference Figures 1 to 7 This embodiment provides a generator set flue gas condensate sampling device, comprising a connecting member 1 connected to a boiler exhaust pipe. Flue gas discharged from the boiler enters the device through the connecting member 1 for condensation and collection. A condensation member 2 is disposed inside the connecting member 1. The flue gas is converted into condensate in the condensation member 2. A cooling member 3 is disposed on the top of the connecting member 1, and a collection member 4 is disposed on the side of the condensation member 2. The cooling member 3 provides a condensation environment for the device. Preferably, ice cubes are placed inside the cooling member 3 to cool the flue gas and condense it into condensate.

[0028] Furthermore, the connecting component 1 includes a chimney 11 directly connected to the boiler exhaust pipe, an inner partition 12 is provided inside the chimney 11, and an opening for allowing flue gas to pass through is opened on the top of the inner partition 12. A conical cooling cylinder 13 is provided on the side of the chimney 11, and the conical cooling cylinder 13 is fixedly connected to the chimney 11. The diameter of the conical cooling cylinder 13 close to the chimney 11 is larger than the diameter of the end away from the chimney 11.

[0029] Furthermore, the condensation member 2 includes a condensation cylinder 21, and a plurality of condensation pipes 22 are provided inside the condensation cylinder 21. Figure 2 As shown, the condensing cylinder 21 is arranged in the conical cooling cylinder 13. The condensing cylinder 21 and the conical cooling cylinder 13 are intended to be conical. The condensing cylinder 21 can rotate in the conical condensing cylinder 21. The interior of the condensing cylinder 21 is divided into several spaces. Due to the provision of the inner partition 12, the flue gas can only enter the condensing cylinder 21 from the top and will only pass through one condensing pipe 22 at a time. The other condensing pipes 22 will not be contaminated. A rotating rod 23 is provided on the side of the condensing pipe 22. A switching structure 24 is provided on the side of the rotating rod 23. The switching structure 24 can quickly switch the condensing pipe 22 that coincides with the opening of the inner partition 12. In this way, a new and uncontaminated pipe can be used each time sampling is performed to ensure the quality of each sample and the quality of inspection.

[0030] Furthermore, an outer baffle 14 is provided at one end of the conical cooling cylinder 13 away from the chimney 11, and an opening is provided above the outer baffle 14 for allowing condensed water to pass through. An intermediate pipe 15 is provided on the side of the outer baffle 14. When the flue gas moves from the condensation cylinder 21 to the outer baffle 14, the flue gas has been cooled and condensed into condensed water under the action of the cooling component 3. The condensed water will enter the intermediate pipe 15 from the opening above the outer baffle 14, and enter the collecting component 4 from the intermediate pipe 15.

[0031] Furthermore, a block 16 is provided above the conical cooling cylinder 13, and a rotation groove 18 is provided on the side of the block 16. Figure 5 As shown, a rotation groove 18 is provided on the side of the clamping block 16 of the conical cooling cylinder 13 , and a retaining ring 17 is provided inside the rotation groove 18 . The retaining ring 17 can rotate inside the rotation groove 18 .

[0032] Furthermore, the condenser tube 21 is arranged inside the conical cooling tube 13, and the outer wall of the condenser tube 21 is in contact with the inner wall of the conical cooling tube 13. The thermal conductivity of the material of the conical cooling tube 13 is good. The heat of the flue gas in the condenser tube 21 is transferred to the conical cooling tube 13 through the inner wall of the condenser tube 21, and then transferred from the conical cooling tube 13 to the cooling member 3. The cooling member 3 absorbs a large amount of heat and quickly cools the flue gas, so that the flue gas is condensed into condensed water. Figure 5 As shown, a condensation channel in the upper part of the condensation tube 21 coincides with the openings of the inner partition 12 and the outer partition 14. Only this condensation channel has flue gas passing through it. The flue gas is hot air and will rise and contact the inner wall and upper wall of the conical condensation tube 21. Figure 5 As shown by the solid arrow in the middle, k in the figure is an ice cube installed in the cold cutting component. The ice cube absorbs the heat in the flue gas in the condensing cylinder 21, so the flue gas is condensed into condensed water when it contacts the upper wall of the condensing cylinder 21. Since the end of the condensing cylinder 21 close to the chimney 11 is the high point and the end of the condensing cylinder 21 away from the chimney 11 is the low point, the condensed water will naturally flow to the end where the middle pipe 15 is located, and the subsequent flue gas continues to condense, forming a water flow from the middle pipe 15 into the collecting component 4, as shown in FIG. Figure 5 Indicated by the dotted arrow.

[0033] Furthermore, the cooling member 3 includes a accommodating box 31 provided at the top of the conical cooling cylinder 13, the accommodating box 31 is provided between the two blocks 16, the side of the accommodating box 31 is in contact with the retaining ring 17, the interior of the accommodating box 31 is hollow, and the side of the accommodating box 31 is provided with an end cover 32. Preferably, the accommodating box 31 can be filled with water in advance, and then the end cover 32 is covered to freeze the water in the accommodating box 31 into ice, and then the accommodating box 31 is installed between the two blocks 16, as shown in FIG. Figure 4As shown, the card block 16 is inclined, and the tops of the two card blocks 16 are closer to each other than the bottoms. After inserting the accommodating box 31 between the two card blocks 16 from the end of the card block 16 close to the smoke pipe 11, the retaining ring 17 is rotated. The retaining ring 17 is not a standard circle. When the maximum point of the outer diameter of the retaining ring 17 is close to the direction where the accommodating box 31 is located, the accommodating box 31 will be locked between the two card blocks 16. At this time, the device can be connected to the smoke exhaust pipe for sampling. If the ice melts, the retaining ring 17 is rotated so that the maximum point of the outer diameter of the retaining ring 17 comes to the bottom away from the position of the accommodating box 31, and the accommodating box 31 can be easily moved to Figure 4 Move out in the direction indicated by the solid arrow, and then replace the pre-prepared receiving box 31. This device can quickly replace the cooling structure, and the ice can be replaced and replenished in time when it melts, so that the quality of the sample is guaranteed.

[0034] Usage process: When sampling flue gas, connect the device to the flue gas exhaust pipe, and the flue gas enters the condensation tube 21 from the upper part of the chimney 11. The flue gas rises and contacts the upper inner wall of the conical condensation tube 21 to become condensed water and flows into the collection member 4. When the ice melts and needs to be replaced, the cooling member 3 can be quickly taken out and replaced with a new cooling member 3. After completing a sampling, the switching structure 24 can be used to make the new condensation channel coincide with the opening above the partition, so that each sampling is a new and uncontaminated condensation channel.

[0035] Example 2, reference Figures 1 to 7 , which is the second embodiment of the present invention. Different from the previous embodiment, the switching structure 24 includes a switching rod 241 sleeved on one end of the rotating rod 23, a ratchet groove is provided on the top of the switching rod 241, and a locking plate 242 is provided on the top of the switching rod 241. The switching rod 241 is rotatably connected to the rotating rod 23, and the switching rod 241 can rotate relative to the rotating rod 23.

[0036] Furthermore, a ratchet 243 is provided at one end of the rotating rod 23 close to the switching rod 241, and the ratchet 243 is fixedly connected to the rotating rod 23. An elastic member 244 is provided on the side of the ratchet 243. Figure 6 As shown, the ratchet teeth 243 cooperate with the ratchet grooves provided on the switch lever 241 .

[0037] Usage process: After completing a sampling, Figure 6 As shown, to switch the condensation channel at this time, you only need to rotate the switching rod 241 clockwise. The ratchet groove on the switching rod 241 will drive the ratchet 243 to rotate, drive the rotating rod 23 to rotate, and drive the condensation tube 21 to rotate. When it rotates to a certain angle so that the next condensation channel coincides with the opening on the upper part of the partition, rotate the switching rod 241 counterclockwise to reset it. At this time, the switching rod 241 will not drive the condensation tube 21 to rotate.

[0038] Example 3, reference Figures 1 to 7 , which is the third embodiment of the present invention, is different from the previous embodiment in that the collecting member 4 includes a movable cylinder 41 arranged on the side of the intermediate pipe 15, and a sampling bottle 42 is arranged at the bottom of the movable cylinder 41. Figure 7 As shown, the movable cylinder 41 is engaged with the middle pipe 15 , and the condensed water flows into the movable cylinder 41 through the middle pipe 15 , and then flows from the movable cylinder 41 into the sampling bottle 42 , thus completing the sampling.

[0039] Furthermore, a locking groove 43 is provided at the bottom of the movable cylinder 41, and the locking groove 43 cooperates with the locking plate 242. In order to ensure that the condensation pipe 22 is not contaminated by the flue gas during each sampling, the condensation pipe 22 needs to be switched each time the sampling is performed, and of course the sampling bottle 42 also needs to be switched. Figure 7 As shown, when the switching rod 241 is in a vertical state, the locking plate 242 is stuck in the locking groove 43, and the movable cylinder 41 cannot escape from the intermediate pipe 15. When switching the condensation pipe 22, the switching rod 241 is rotated clockwise to switch the condensation pipe 22. At the same time, the locking plate 242 leaves the locking groove 43. At this time, the movable cylinder 41 can be taken out from the intermediate pipe 15 together with the sampling bottle 42, and then a new movable cylinder 41 and sampling bottle 42 are replaced and inserted into the intermediate pipe 15. The switching rod 241 is rotated counterclockwise again, and the locking plate 242 returns to the locking groove 43. The movable cylinder 41 is locked, and a new sampling can be carried out at this time. The device can switch the sampling condensation channel to ensure that the condensation channel is not contaminated during each sampling, thereby ensuring the sample quality, eliminating errors, and making the test more accurate.

[0040] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
