Description

Technical Field

[0001] The utility model relates to the technical field of water vapor sampling, in particular to convenient-to-use water vapor sampling equipment for power plants. Background Art

[0002] In order to ensure the quality of water vapor in thermal power plant boilers, plants need to regularly extract samples from the water vapor system for quality inspection. However, due to the high initial temperature of the water vapor, the operating procedure usually involves condensing the water vapor first and then using the condensed water as a test sample. Despite this, the temperature of the condensed water is still high and the cooling process is slow, which not only brings inconvenience to the staff during the sampling process, but also adds risks to their safety. Existing sampling devices have obvious deficiencies in convenience and safety and need to be improved urgently.

[0003] Therefore, a convenient-to-use power plant water vapor sampling device is proposed to solve or alleviate the above problems. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model discloses a convenient water vapor sampling device for a power plant, comprising a condensation box and a condensation column arranged through the condensation box, wherein the condensation column passes through the condensation box from top to bottom, and the lower end of the condensation column is buried in the ground.

[0007] Preferably, one side wall of the condensation box is fixedly connected with an air intake pipe communicating with the interior, and the air intake pipe can be opened and closed.

[0008] Preferably, the air intake pipe is connected to a solenoid valve, and the solenoid valve controls the opening and closing of the air intake pipe.

[0009] Preferably, a water outlet pipe connected to the interior of the condensing box is fixedly connected to one side wall of the condensing box, the lowest level of the inner circle of the water outlet pipe is flush with the inner bottom surface of the condensing box, and the water outlet pipe is connected to a stop valve and a water pump in sequence.

[0010] Preferably, the top surface and the inner bottom surface of the condensation box are both provided with a sealing component wrapped around the outside of the condensation column.

[0011] Preferably, the top and bottom surfaces of the condensation box are both provided with coaxially arranged through holes for the condensation column to pass through, and the sealing assembly includes a soft rubber sleeve with a diameter that gradually decreases from bottom to top, and a sealing cylinder fixedly connected to the end of the soft rubber sleeve with the smallest opening area, the large-diameter end of the soft rubber sleeve is fixedly connected to the through hole, and the sealing cylinder is arranged to fit the outer peripheral wall of the condensation column.

[0012] Preferably, the lower end of the condensation column is configured as a cone.

[0013] The utility model has the following beneficial effects:

[0014] During use, by periodically operating the solenoid valve, the water vapor of the power plant is guided to the condensation box through the air inlet pipe, and condensed into liquid after contacting the condensation box and metal condensation column with lower temperature than itself. This metal condensation column continuously exchanges heat with the ground to maintain low temperature and effectively condense water vapor. When the condensed liquid accumulates to a certain amount, it will be discharged through the outlet pipe, stop valve and water pump in turn. The stop valve prevents the liquid from flowing out when it is insufficient, and the carefully designed sealing components ensure that the condensation column and condensation box are easy to assemble and leak-free.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Convenient power plant water vapor sampling equipment, such as Figure 2 As shown, it includes a condensation box 1 and a condensation column 4 that passes through the condensation box 1 . The condensation column 4 passes through the condensation box 1 from top to bottom, and the lower end of the condensation column 4 is buried underground. The lower end of the condensation column 4 is set as a cone 401 .

[0020] The top surface and the inner bottom surface of the condensation box 1 are both provided with sealing components wrapped around the outside of the condensation column 4. The top and bottom surfaces of the condensation box 1 are both provided with coaxially arranged through holes for the condensation column 4 to pass through. The sealing components include a soft rubber sleeve 501 with a diameter that gradually decreases from bottom to top, and a sealing cylinder 502 fixedly connected to the end of the soft rubber sleeve 501 with the smallest opening area. The large-diameter end of the soft rubber sleeve 501 is fixedly connected to the through hole, and the sealing cylinder 502 is arranged to fit the outer peripheral wall of the condensation column 4. The soft rubber sleeve 501 is made of fluororubber, and the sealing cylinder 502 is in the shape of a circular tube and is made of 304 stainless steel.

[0021] And, if Figure 1As shown, one side wall of the condensation box 1 is fixedly connected with an air inlet pipe 2 connected with the interior, the air inlet pipe 2 can be opened and closed, the air inlet pipe 2 is connected with a solenoid valve 201, the solenoid valve 201 controls the opening and closing of the air inlet pipe 2, and at the same time, the other side wall of the condensation box 1 is fixedly connected with a water outlet pipe 3 connected with the interior, the lowest horizontal height position of the inner circle of the water outlet pipe 3 is flush with the inner bottom surface of the condensation box 1, and the water outlet pipe 3 is connected with a stop valve 301 and a water pump 302 in sequence.

[0022] When installing the device according to the utility model, it is only necessary to pre-bury the alloy condensation column 4 into the ground with the cone 401 facing the ground, and then lift the condensation box 1, align the through hole with the upper end of the condensation column 4, and apply a downward pressing force to the condensation box 1, so that the condensation column 4 and the condensation box 1 can be relatively displaced, and the condensation column 4 passes through the through hole, the soft rubber sleeve 501, and the sealing cylinder 502 until the bottom surface of the condensation box 1 is in contact with the ground, and then the solenoid valve 201 is installed on the air inlet pipe 2, and the stop valve 301 and the water pump 302 are installed on the water outlet pipe 3 in sequence. When using it later, it is only necessary to intermittently open and close the solenoid valve 201 to allow the water vapor from the power plant to enter the condensation box through the air inlet pipe 2. In the box 1, when the water vapor comes into contact with the condensation box 1 and the condensation column 4 whose temperatures are lower than the water vapor, it will be condensed into liquid when it encounters cold, and then the liquid will accumulate in the condensation box 1. In this process, the condensation column 4 is made of metal and always exchanges heat with the underground to maintain a low temperature, so that the water vapor can be condensed continuously. Finally, after a certain amount of liquid is accumulated, it can leave through the outlet pipe 3, the stop valve 301, and the water pump 302 in sequence. The stop valve 301 prevents the liquid from leaving the outlet pipe 3 when there is less liquid. The setting of the sealing component makes it easier to assemble the condensation column 4 and the condensation box 1. After assembly, the position where the condensation column 4 passes through the condensation box 1 is not prone to leakage.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
