A vacuum pump set with a water accumulation warning function

Abstract

The present invention discloses a vacuum pump group with a water accumulation warning function, belonging to the field of vacuum pumps. The present invention adds a condenser pipe with a V-shaped structure between the vacuum pump body and the steam delivery pipe. The water vapor discharged from the steam delivery pipe is cooled by a plurality of water-cooled pipes through which coolant flows to form condensate, which is then led downward into the liquid storage hopper. Cooling and coagulation assistance are carried out before the water vapor enters the vacuum pump body to prevent a large amount of condensate from accumulating at the inlet of the vacuum pump. The condensate is collected through the liquid storage hopper. When the condensate rises to the humidity sensor, the humidity sensor detects a relatively high humidity, and the drain valve is controlled to open through an external controller to drain the accumulated water at the liquid storage hopper. When the color-developing petals inside the color display warning ring turn color when encountering water, it indicates that the condensate has not been successfully discharged through the drain pipe. The condensate continues to rise and enters the color display warning ring, playing a role of sensory display warning for technicians to check whether the condensate inside the liquid storage hopper is normally discharged and timely solve the drainage failure.

Description

Technical Field

[0001] The present invention relates to the field of vacuum pumps, and more specifically, to a vacuum pump group with a water accumulation warning function. Background Art

[0002] The condenser vacuum system, as an important part of the thermal system of a power plant, the stable operation and the protection interlock being safe and reliable are the keys to ensuring the normal operation of the unit. During operation, generally two vacuum pumps are equipped, one vacuum pump is in operation, and one vacuum pump is in standby with interlock;

[0003] The function of the vacuum pump is to extract the condensed gas mixture in the condenser during the operation of the unit. There is a pressure switch at the front of the vacuum pump inlet for starting the standby vacuum pump in case of low inlet vacuum. Since the vacuum pumps are switched regularly once a month, a large amount of condensed water will accumulate in front of the inlet of the standby vacuum pump for a long time, blocking the pressure guiding pipe of the pressure switch for starting the standby vacuum pump due to low inlet vacuum, resulting in a low inlet vacuum signal at the inlet of the standby vacuum pump. Currently, when the low inlet vacuum signal of the standby vacuum pump comes, the vacuum pump is powered off. After the operator closes the manual valve at the inlet of the standby vacuum pump, the maintenance personnel remove the accumulated water in the inlet pressure guiding pipe. During this period, the vacuum pump loses its effective standby. This traditional operation is rather cumbersome. The vacuum pump also loses its standby function during the removal of the accumulated water, and manual operation by personnel will increase potential safety hazards;

[0004] Therefore, we propose a vacuum pump group with a water accumulation warning function to effectively solve the actual problems existing in the prior art. Summary of the Invention

[0005] The present invention provides a vacuum pump group with a water accumulation warning function to solve the technical defects proposed in the background art.

[0006] The object of the present invention can be achieved by the following technical solutions: A vacuum pump group with a water accumulation warning function includes a vacuum pump body and a steam delivery pipe that are connected and communicated with each other. A condensing pipe is connected between the outlet end of the steam delivery pipe and the inlet of the vacuum pump body. The condensing pipe includes a first condensing half-pipe and a second condensing half-pipe that are connected to each other. The end of the second condensing half-pipe away from the first condensing half-pipe is connected to the outlet end of the steam delivery pipe, and the end of the first condensing half-pipe away from the second condensing half-pipe is connected to the inlet of the vacuum pump body. A plurality of water cooling pipes are distributed at the inner end of the second condensing half-pipe. One ends of the plurality of water cooling pipes are fixedly connected to a liquid inlet pipe that extends to the outside of the top end of the second condensing half-pipe. The other ends of the plurality of water cooling pipes extend into the first condensing half-pipe and are fixedly connected to a liquid outlet pipe that penetrates to the outside of the first condensing half-pipe. The lower end wall at the docking place of the first condensing half-pipe and the second condensing half-pipe is fixedly communicated with a liquid storage hopper. The bottom end of the liquid storage hopper is connected with a liquid discharge pipe, and a drain valve is arranged at the end where the liquid discharge pipe is connected to the liquid storage hopper;

[0007] A flow guide cone tube is fixedly connected inside the liquid storage hopper, which is connected to the inner wall of its top end and extends to its inner bottom. A detection area is formed between the outer wall of the flow guide cone tube and the inner wall of the liquid storage hopper. A color display warning ring corresponding to the top position of the flow guide cone tube is fixedly embedded on the outer wall of the top end of the liquid storage hopper. A liquid passage groove communicating with the inside of the detection area is provided on the inner end wall of the color display warning ring. The color display warning ring is a hollow annular structure, and a color display flap is attached to the inner side end wall of the color display warning ring. A humidity sensor located at the top of the detection area is fixedly installed on the inner wall of the liquid storage hopper below the color display warning ring.

[0008] Furthermore, the first half condensation tube and the second half condensation tube cooperate to form a V-shaped structure. The liquid storage hopper is a conical structure that is narrower at the top and wider at the bottom. A plurality of downward-extending flow guide cones are fixedly connected to the lower end wall of the liquid storage hopper above the water cooling tubes. Setting the condensation tubes in a V-shaped structure is beneficial for the water vapor flowing through the second half condensation tube and the first half condensation tube to form condensed water after encountering the water cooling tubes. The condensed water is guided downward along the inner end walls of the second half condensation tube and the first half condensation tube into the liquid storage hopper, facilitating the collection of the condensed water.

[0009] Furthermore, the first half condensation tube, the second half condensation tube, and the plurality of water cooling tubes are all made of heat-conducting materials, and the liquid inlet pipe is communicated with the coolant cold source.

[0010] Furthermore, the color display warning ring is made of a transparent material, and the color display flap is a double-layer structure made of a transparent fiber material. The inside of the color display flap is filled with anhydrous copper sulfate powder. After the condensed water inside the liquid storage hopper gradually increases and spreads upward along the outer end wall of the flow guide cone tube, when the condensed water rises to the humidity sensor, at this time, the humidity sensor detects a relatively high humidity, and the drain valve is controlled to open through an external controller to drain the accumulated water inside the liquid storage hopper. When the color display flap inside the color display warning ring turns color when encountering water, it indicates that the condensed water has not been successfully discharged through the drain pipe, and the condensed water continues to rise and enters the color display warning ring, thus playing a sensory display warning role for technicians to timely check whether the condensed water inside the liquid storage hopper is discharged normally and effectively avoid drainage failures.

[0011] Furthermore, the first half condensation tube includes a lower half tube fixedly connected to the second half condensation tube. An upper half tube connected to the inlet of the vacuum pump body is provided above the lower half tube. A moisture filtering tube is fixedly sleeved between the lower half tube and the upper half tube, and a filter layer is embedded inside the moisture filtering tube.

[0012] Furthermore, a supporting component for supporting the moisture filtering tube is fixedly sleeved on the upper half tube. The supporting component includes a docking sleeve fixedly sleeved on the upper half tube. The lower end wall of the docking sleeve close to the lower half tube is fixedly connected with a receiving flap matching the moisture filtering tube, and the lower end of the receiving flap is fixedly connected to the top end of the lower half tube.

[0013] Further, magnetic layers that are magnetically attracted to each other are embedded in the bottom end face of the moisture filter pipe and the inner end face of the receiving flap. Sealing rings that fit with the upper half pipe and the lower half pipe are fixedly connected to both the left and right end walls of the moisture filter pipe. The moisture filter pipe can be detached from the supporting component, facilitating the replacement and cleaning of the gas filtering layer inside the moisture filter pipe. After docking and installation, a whole circulation of the condensation half pipe is achieved without affecting the transportation of water vapor.

[0014] Further, a heat conduction component is embedded in the gas filtering layer. Both ends of the heat conduction component penetrate through the moisture filter pipe and extend outward to be fixedly connected to the inner wall of the steam delivery pipe.

[0015] Further, the heat conduction component includes a heat conduction pipe embedded in the gas filtering layer. The left and right ends of the heat conduction pipe penetrate through the gas filtering layer and extend outward respectively. A heat conduction sheet that fits and connects with the gas filtering layer is inserted on the end wall of the heat conduction pipe located inside the moisture filter pipe.

[0016] Further, perforations for the heat conduction pipe to penetrate through are provided on the moisture filter pipe. Circulation pipes connected to both ends of the heat conduction pipe are fixedly connected to the end wall of the steam delivery pipe. During operation, the circulation pipes are connected and communicated with the heat conduction pipe. A part of the water vapor inside the steam delivery pipe circulates inside the heat conduction pipe, increasing the temperature at the heat conduction pipe, and the gas after removing moisture is filtered through the gas filtering layer to further remove the moisture that has not been completely removed. The heat conduction pipe with heat conduction function can play a certain heating role on the gas filtering layer, keeping the gas filtering layer in a dry state all the time and improving its moisture removal effect.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] (1) In this solution, a condensation pipe in a V-shaped structure is added between the vacuum pump body and the steam delivery pipe. The water vapor discharged from the steam delivery pipe is cooled by multiple water cooling pipes flowing through coolant to form condensed water, which is downwardly introduced into the liquid storage hopper. Cooling and coagulation are carried out before the water vapor enters the vacuum pump body to prevent a large amount of condensed water from accumulating at the inlet of the vacuum pump. The condensed water is collected through the liquid storage hopper. When the condensed water rises to the humidity sensor, the humidity sensor detects a large humidity, and the drain valve is controlled to open through an external controller to drain the accumulated water at the liquid storage hopper. When the color display flap inside the color display warning ring turns color when encountering water, it indicates that the condensed water has not been successfully discharged through the drain pipe. The condensed water continues to rise and enters the color display warning ring, thus playing a sensory display warning role for technicians to check whether the condensed water inside the liquid storage hopper is normally discharged and timely solve the drainage failure.

[0019] (2) This scheme also optimizes the design of the condensing half-tube and adds a filter layer with moisture adsorption at one end of the condensing half-tube. The steam after the initial moisture removal by the water-cooling pipe is continuously introduced into the filter layer for secondary moisture adsorption, thereby improving the dryness of the gas introduced into the vacuum pump body. The circulation pipe is connected to the heat transfer pipe, and the water vapor inside the steam delivery pipe circulates in the heat transfer pipe to increase the temperature at the heat transfer pipe. The heat transfer pipe with heat conduction function can heat the filter layer to a certain extent, so that the filter layer always remains dry and its moisture removal effect is improved.

[0029] The following will combine the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0030] Example 1:

[0031] The present invention discloses a vacuum pump group with a water accumulation warning function. Please refer to Figure 1 - Figure 2 , which includes a vacuum pump body 1 and a steam delivery pipe 2 that are connected and communicated with each other. A condensation pipe is connected between the outlet end of the steam delivery pipe 2 and the inlet of the vacuum pump body 1. The condensation pipe includes a condensation half-pipe one 3 and a condensation half-pipe two 4 that are connected to each other. One end of the condensation half-pipe two 4 away from the condensation half-pipe one 3 is connected to the outlet end of the steam delivery pipe 2, and one end of the condensation half-pipe one 3 away from the condensation half-pipe two 4 is connected to the inlet of the vacuum pump body 1. A plurality of water-cooling pipes 10 are distributed at the inner end of the condensation half-pipe two 4. One ends of the plurality of water-cooling pipes 10 are fixedly connected to a liquid inlet pipe 11 that extends to the outside of the top end of the condensation half-pipe two 4. The other ends of the plurality of water-cooling pipes 10 extend into the condensation half-pipe one 3 and are fixedly connected to a liquid outlet pipe 12 that penetrates to the outside of the condensation half-pipe one 3. A liquid receiving hopper 5 is fixedly communicated with the lower end wall at the docking position of the condensation half-pipe one 3 and the condensation half-pipe two 4. A drain pipe 6 is connected to the bottom end of the liquid receiving hopper 5, and a drain valve is provided at the communicating end of the drain pipe 6 and the liquid receiving hopper 5.

[0032] Please refer to Figure 4 , Figure 6 , Figure 7 , the condensation half-pipe one 3 and the condensation half-pipe two 4 cooperate to form a V-shaped structure. The liquid receiving hopper 5 is a conical structure with a narrow upper part and a wide lower part. A downward-extending diversion cone 101 is fixedly connected to the lower end wall of the plurality of water-cooling pipes 10 above the liquid receiving hopper 5. The condensation half-pipe one 3, the condensation half-pipe two 4, and the plurality of water-cooling pipes 10 are all made of heat-conducting materials, and the liquid inlet pipe 11 is communicated with a coolant cold source. A plurality of water-cooling pipes 10 for circulating the coolant are added to realize the cooling and condensation of water vapor in the added condensation pipe, so as to prevent the water vapor from condensing at the vacuum pump inlet and causing too much condensed water to accumulate at the vacuum pump inlet. The condensation pipe is set as a V-shaped structure, which is beneficial to guiding the condensed water downward along the inner end walls of the condensation half-pipe two 4 and the condensation half-pipe one 3 into the liquid receiving hopper 5, facilitating the collection of the condensed water.

[0033] A liquid storage hopper 5 is fixedly connected inside with a diversion cone tube 9 that is connected to the inner wall of its top end and extends to its inner bottom. A detection area is formed between the outer wall of the diversion cone tube 9 and the inner wall of the liquid storage hopper 5. The outer wall of the top end of the liquid storage hopper 5 is fixedly embedded with a color display warning ring 7 that is arranged corresponding to the top position of the diversion cone tube 9. A liquid passage groove that is communicated with the inside of the detection area is opened on the inner end wall of the color display warning ring 7. The color display warning ring 7 is a hollow annular structure inside, and a color display flap 8 is attached to the inner side end wall of the color display warning ring 7. A humidity sensor located at the top of the detection area is fixedly installed on the inner wall of the liquid storage hopper 5 below the color display warning ring 7. Condensed water is collected through the liquid storage hopper 5. Since the diversion cone tube 9 that is connected to the inner wall of its top end is provided inside the liquid storage hopper 5, the condensed water is introduced into the inner bottom of the liquid storage hopper 5 along the inside of the diversion cone tube 9. After the condensed water continuously increases, it will rise and spread along the outer wall of the diversion cone tube 9 to the detection area formed by the liquid storage hopper 5 and the diversion cone tube 9. When the condensed water rises to the humidity sensor, the humidity sensor detects a relatively high humidity, and controls the drain valve to open through an external controller to drain the accumulated water inside the liquid storage hopper 5.

[0034] The color display warning ring 7 is made of a transparent material. The color display flap 8 is a double-layer structure made of a transparent fiber material. The inside of the color display flap 8 is filled with anhydrous copper sulfate powder. Technicians can also choose other materials that change color when encountering water to meet the color display changes before and after encountering water. After the condensed water inside the liquid storage hopper 5 gradually increases and rises along the outer end wall of the diversion cone tube 9, when the color display flap 8 inside the color display warning ring 7 shows color when encountering water, it indicates at this time that the condensed water has not been successfully discharged through the drain pipe 6, and the condensed water continuously rises along the detection area and enters the color display warning ring 7, thus playing a sensory display warning role for technicians to timely check whether the condensed water inside the liquid storage hopper 5 is normally discharged and effectively avoid drainage failures.

[0035] Embodiment 2:

[0036] In this embodiment, on the basis of Embodiment 1, the first half condenser tube 3 is optimized, and a gas filtering layer 14 with moisture adsorption is added at the first half condenser tube 3, which is beneficial to the secondary moisture removal of the gas with incompletely removed moisture and improves the dryness of the gas introduced into the vacuum pump body 1.

[0037] Please refer to Figure 2 - Figure 4, as follows: The first condensate half-tube 3 includes a lower half-tube 31 fixedly connected to the second condensate half-tube 4. Above the lower half-tube 31, there is an upper half-tube 32 connected to the inlet of the vacuum pump body 1. A moisture filtration tube 33 is fixedly sleeved between the lower half-tube 31 and the upper half-tube 32. A filter layer 14 is embedded inside the moisture filtration tube 33. An upper half-tube 32 is fixedly sleeved with a support assembly 13 for supporting the moisture filtration tube 33. The support assembly 13 includes a docking sleeve 131 fixedly sleeved on the upper half-tube 32. The lower end wall of the docking sleeve 131 close to the lower half-tube 31 is fixedly connected with a receiving flap 132 matching the moisture filtration tube 33. The lower end of the receiving flap 132 is fixedly connected to the top end of the lower half-tube 31. Magnetic layers that are magnetically attracted to each other are embedded on the bottom end face of the moisture filtration tube 33 and the inner end face of the receiving flap 132. Sealing rings that are fitted to the upper half-tube 32 and the lower half-tube 31 are fixedly connected to both left and right end walls of the moisture filtration tube 33. The moisture filtration tube 33 can be detached from the support assembly 13, facilitating the replacement and cleaning of the filter layer 14 inside the moisture filtration tube 33. After docking and installation, the first condensate half-tube 3 is in overall circulation, without affecting the transportation of water vapor. The vapor with preliminary moisture removal is introduced to the filter layer 14 for secondary moisture adsorption, improving the dryness of the gas introduced into the vacuum pump body 1.

[0038] In addition, a heat conduction assembly is embedded inside the filter layer 14. Both ends of the heat conduction assembly respectively penetrate through the moisture filtration tube 33 and extend outward to be fixedly connected to the inner wall of the steam delivery tube 2. The heat conduction assembly includes a heat conduction tube 15 embedded in the filter layer 14. The left and right ends of the heat conduction tube 15 respectively penetrate through the filter layer 14 and extend outward. A heat conduction fin 17 that is fitted and connected to the filter layer 14 is also inserted on the end wall of the heat conduction tube 15 located inside the moisture filtration tube 33. The moisture filtration tube 33 is provided with a perforation for the heat conduction tube 15 to penetrate through. Circulation tubes 16 respectively fixedly connected to both ends of the heat conduction tube 15 are fixedly connected to the end wall of the steam delivery tube 2. During operation, the circulation tubes 16 are connected and communicated with the heat conduction tube 15. A part of the water vapor inside the steam delivery tube 2 circulates inside the heat conduction tube 15, increasing the temperature at the heat conduction tube 15. The gas after preliminary moisture removal is filtered by the filter layer 14 to further remove the moisture that has not been completely removed. The heat conduction tube 15 with heat conduction function can play a certain heating role on the filter layer 14, keeping the filter layer 14 in a dry state all the time and improving its moisture removal effect.

[0039] This scheme is combined with Example 1 and Example 2. By adding a condenser tube with a V-shaped structure between the vacuum pump body 1 and the steam delivery pipe 2, the condenser tube is composed of a condenser half pipe 1 3 and a condenser half pipe 2 4 that are connected and connected to each other, and the water vapor discharged from the steam delivery pipe 2 passes through a plurality of water cooling pipes 10 through which a coolant flows. After the water vapor contacts the water cooling pipe 10, it is cooled to form condensed water. The condensed water is introduced downward into the liquid storage bucket 5 along the outer end wall of the water cooling pipe 10 and the inner end wall of the condenser half pipe 2 4 and the condenser half pipe 1 3. The condensed water is collected by the liquid storage bucket 5, and the water vapor is cooled and condensed before entering the vacuum pump body 1, so as to avoid a large amount of condensed water accumulating at the inlet of the vacuum pump.

[0040] The condensed water is led out to the inside of the liquid storage bucket 5 through the guide cone 9. When the condensed water rises from the bottom of the liquid storage bucket 5 to the detection area, when the humidity sensor detects a high humidity, the drain valve is controlled to open by the external controller to discharge the water inside the liquid storage bucket 5. This is a normal water accumulation and drainage operation. When the color of the color petal 8 inside the color warning ring 7 changes back and forth, it indicates that the condensed water is not discharged smoothly through the drainage pipe 6. The condensed water continues to rise and enters the color warning ring 7, causing the color petal 8 to change color when it encounters water, thereby playing a sensory display warning role for the technicians to check whether the condensed water inside the liquid storage bucket 5 is discharged normally and solve the drainage fault in time.

[0041] The steam after the preliminary dehumidification by the water-cooling pipe 10 continues to be introduced into the air filter layer 14 for secondary moisture adsorption, thereby improving the dryness of the gas introduced into the vacuum pump body 1, and the circulation pipe 16 is connected with the heat pipe 15. The water vapor inside the steam delivery pipe 2 circulates in the heat pipe 15 to increase the temperature at the heat pipe 15. The heat pipe 15 with heat conduction function can heat the air filter layer 14 to a certain extent, thereby ensuring that the air filter layer 14 always remains in a dry state and improving its moisture removal effect.

[0042] The above description is only a preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto; any technician familiar with the technical field within the technical scope disclosed by the present invention; any equivalent replacement or change based on the technical solution and improved concept of the present invention shall be covered by the protection scope of the present invention.
