Abstract
Description
Technical Field
[0001] The invention relates to the field of condensate sampling, in particular to a unit condensate quantitative sampler. Background Art
[0002] Condensate sampling is crucial during generator set operation. Condensate is formed when steam cools after working in the turbine. After treatment, it is recycled as boiler feed water. Substandard condensate directly impacts the water quality within the boiler. Condensate containing impurities such as calcium, magnesium ions, and silicon compounds will evaporate at high temperatures upon entering the boiler, forming scale. Scale reduces boiler heat transfer efficiency, increases fuel consumption, and can even cause serious accidents such as boiler tube bursts. Excessive levels of dissolved oxygen, carbon dioxide, and chloride ions in the condensate can cause electrochemical corrosion of boiler, piping, and turbine components. For example, a dissolved oxygen concentration exceeding 0.1 mg / L accelerates oxygen corrosion in carbon steel piping, while excessive chloride ions can cause stress corrosion cracking in stainless steel components.

[0028] 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.
[0029] 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.
[0030] Reference Figures 1 to 5 This embodiment provides a unit condensate quantitative sampler, including a connecting part 100 for connecting a sampling point; the connecting part 100 is a tube structure, the connecting part 100 includes an interface end 101 for connecting a sampling point, the connecting part 100 also includes a discharge end 102 facing the quantitative part 200, and the connecting part 100 also includes a first valve 103.
[0031] The interface end 101 can adopt a quick-release interface. In order to improve the stability of the connection, a threaded connection can also be adopted. In daily use, the interface end 101 always remains connected to the sampling point. The first valve 103 adopts an electromagnetic valve, which can control the opening and closing of the first valve 103, and can connect the sampling point and the connection part 100. When the first valve 103 is in a closed state, the condensed water at the sampling point will not enter the inner side of the connection part 100. When the first valve 103 is in an open state, the condensed water at the sampling point can enter the inner side of the connection part 100.
[0032] In actual work, the first valve 103 may be controlled by a PLC so that the first valve 103 is opened once at a certain time interval, thereby achieving condensed water sampling work once at a certain time interval.
[0033] The unit condensate quantitative sampler also includes a quantitative part 200, including a cup body 201. Condensate can enter the quantitative part 200 through the connecting part 100. The function of the quantitative part 200 is to ensure that each time water is taken, a certain amount can be reached to facilitate subsequent testing.
[0034] The unit condensate quantitative sampler also includes a receiving portion 300, which is arranged below the quantitative portion 200. The receiving portion 300 is provided for the purpose of receiving the condensate poured out from the cup body 201 and collecting the obtained condensate.
[0035] The unit condensate quantitative sampler also includes a collecting part 400, which is connected to the receiving part 300; when the condensate inside the cup body 201 reaches a predetermined amount, the cup body 201 can be turned over, and the condensate inside the cup body 201 can enter the receiving part 300 and enter the collecting part 400 through the receiving part 300.
[0036] Specifically, the unit condensate quantitative sampler also includes a frame 500, and the connecting part 100, the quantitative part 200, and the receiving part 300 are all installed on the frame 500. The entire frame 500 is used to provide an installation position for the connecting part 100, the quantitative part 200, and the receiving part 300.
[0037] The frame 500 includes a base 501, a limiting member 502 and a bracket 503, wherein the bracket 503 is located at the top of the entire frame 500, the limiting member 502 is located below, and then the base 501 is at the bottom. The receiving portion 300 is installed on the base 501, the limiting member 502 can limit the cup body 201, and the connecting portion 100 is installed on the bracket 503. In this embodiment, the receiving portion 300 is directly tracked on the base 501, and the limiting member 502 can limit the cup body 201, avoiding To avoid the problem of the cup body 201 flipping over when it is loaded with a predetermined amount of condensed water, the cup body 201 can move relative to the limiting part 502. When the condensed water in the cup body 201 reaches a predetermined amount, the cup body 201 and the limiting part are separated. At this time, the cup body 201 is no longer limited by the limiting part 502, and the cup body 201 can flip over. After flipping, the water inside the cup body 201 can enter the inner side of the receiving part 300, and finally enter the inner side of the collecting part 400 through the receiving part 300.
[0038] The quantitative portion 200 includes an elastic member 202, a sliding member 203 that abuts against the elastic member 202, and a rotating shaft 204 mounted on the sliding member 203; the rotating shaft 204 is connected to the cup body 201, wherein the elastic member 202 is a spring, and a guide column 504 is mounted on the base 501, the number of the guide columns 504 is two, the number of the elastic members 202 is also two, the two elastic members 202 are respectively sleeved on the outside of the two guide columns 504, in this embodiment, the number of the sliding members 203 is two, the two sliding members 203 are respectively sleeved on the outside of the two guide columns 504, the sliding members 203 and the elastic member 202 abut, the number of the rotating shafts 204 is two, and the two rotating shafts 204 are respectively rotatably mounted on the two sliding members 203, so that the cup body 201 can rotate relative to the sliding members 203.
[0039] As shown in the figure, the limiting member 502 is a circular tubular structure, and the inner wall of the limiting member 502 is divided into two parts, namely the first area 505 and the second area 506, wherein the length of the first area 505 is greater than the second area 506, and the top of the outer wall of the entire cup body 201 fits with the inner wall of the limiting member 502. When the cup body 201 is separated from the limiting member 502, it can flip over, and the second area 506 at the end can prevent the cup body 201 from being interfered with by the second area 506 when flipping.
[0040] In this embodiment, the cup body 201 is an inverted cone structure, the top of the cup body 201 has a maximum diameter, and is adapted to the inner diameter of the limiting member 502. In the absence of external force, the elastic member 202 supports the sliding member 203, and the sliding member 203 maintains the position of the rotating shaft 204 and thus maintains the position of the cup body 201, so that the cup body 201 remains in contact with the inner wall of the limiting member 502.
[0041] A barrier 205 is provided on the cup body 201, and the barrier 205 divides the internal space of the cup body 201 into a load-bearing part 206 and an unloaded part 207. As shown in the figure, the barrier 205 is installed inside the cup body 201, and the bottom of the barrier 205 is inclined toward the load-bearing direction, and the top of the barrier 205 is inclined toward the unloaded part 207. In this way, when the connecting pipe is opened to transport condensed water into the cup body 201, the barrier 205 will not block the cup mouth of the cup body 201, so that the condensed water can smoothly enter the interior of the cup body 201.
[0042] We mark the central axis of the cup body 201. When the condensed water enters the cup body 201, it can only enter the load-bearing part 206. Due to the obstruction of the barrier 205, the condensed water cannot enter the unloaded part 207 of the cup body 201. As the amount of water increases, the volume of the condensed water on the left side of the central axis will be obviously larger than the volume of the condensed water on the right side of the central axis. That is to say, the weight of the condensed water on the left side is greater than the weight of the condensed water on the right side. If the limit of the limiter 502 is lost, the cup body 201 will tilt and flip to the left, causing the condensed water inside the cup body 201 to pour out from the cup mouth and enter the receiving part 300 below, and then enter the collection part 400 through the receiving part 300.
[0043] As the condensed water in the cup body 201 continues to increase, the overall weight of the cup body 201 increases, which increases the force pressing the elastic member 202, and the elastic member 202 will shrink downward. At this time, under the action of the guide column 504, the sliding member 203 will move downward along the guide column 504, so the cup body 201 will also move downward until it is separated from the limit member 502. After separating from the limit member 502, because the overall center of gravity of the cup body 201 is not on the central axis, the cup body 201 will flip over and discharge the condensed water inside it.
[0044] Because the contraction distance of the elastic member 202 is related to the pressure it is subjected to, each time the cup body 201 is able to press the elastic member 202 to the position where the cup body 201 is separated from the limit member 502, the weight of the cup body 201 is almost the same, and the weight of the condensed water inside the cup body 201 is also basically the same, achieving the effect of quantitative sampling. More preferably, an angular velocity sensor can be installed on the cup body 201, and the angular velocity sensor is connected to the PLC. When the cup body 201 flips over, the angular velocity sensor transmits an electrical signal to the PLC, and at this time the PLC controls the first valve 103 to close.
[0045] A balancing groove 208 is provided on the cup body 201 near the empty part 207. Because the barrier 205 is inclined toward the empty part 207, the balancing groove 208 is provided on the cup body 201 so that the center of gravity of the entire cup body 201 when empty can be on the central axis. When the water inside the cup body 201 is poured out, it can automatically restore to a balanced state. More preferably, a torsion spring is installed between the sliding member 203 and the rotating shaft 204 to help the rotating shaft 204 and the cup body 201 return to a balanced state after pouring the water.
[0046] The receiving part 300 includes a collecting bucket 301 provided below the cup body 201, and a conveying pipe 302 connected to the collecting bucket 301. After the condensed water inside the cup body 201 is poured out, it can enter the interior of the collecting bucket 301, and then under the action of gravity, the condensed water enters the interior of the conveying pipe 302 from the interior of the collecting bucket 301.
[0047] The collecting part 400 includes a diversion structure 401 connected to the delivery pipe 302. The diversion structure 401 has multiple diversion lines, each of which is connected to a container 402. A second valve 403 is installed on each diversion line, wherein the second valve 403 is an electromagnetic valve and is also controlled by a PLC. In this way, each time a sample is taken, the second valve 403 on a different diversion line is opened, so that each time a sample is taken, a certain amount of condensed water can enter the interior of a different container 402.
