Description
Technical Field
The utility model relates to a circulating water system for a vacuum pump, in particular to an energy-saving water tank system of a water ring vacuum pump.
Background
The water ring vacuum pump in the spandex refining system is commonly used, and the circulating water system for the vacuum pump comprises a water tank 1', a circulating water pump 2', a water supply and return pipeline, a plate heat exchanger 3', a vacuum pump 4', a water supplementing system and a water draining system (figure 1); as shown in fig. 2 and 3, the water tank 1' is cylindrical, and is provided with a water supplementing port 11', a water returning port 12', a pump inlet 13' and a drain outlet 14' at the bottom. As shown in fig. 1, the water replenishing system provides water tank with water of 25 deg.c, and then through the plate heat exchanger to obtain water of 10-15 deg.c, so as to provide vacuum pump with circulating water of low temperature. The vacuum pump drives the circulating water to rotate at a high speed in the pump body to form centrifugal force and generate negative pressure, so that the refined tower system is pumped with negative pressure, and meanwhile, partial decomposition products generated by the tower system are dissolved in the circulating water through the vacuum pump water circulation system and are discharged through the drainage system.
Since the tower system contains various impurities (including ammonia) which, when dissolved in the circulating water, make the water higher and higher in concentration and smell and even affect the performance of the vacuum pump, it is necessary to perform the draining and the water replenishing regularly. The currently used vacuum pump water ring system adopts continuous low-flow drainage, and after the liquid level reaches a set low level, an automatic water supplementing system is triggered to start water supplementing, and water supplementing is stopped until the liquid level reaches a high limit. This design has the following drawbacks:
(1) When stage drainage is carried out, the drainage amount is not well controlled every time, because only a limited amount of water is supplemented, the water is supplemented, and the mixing of a large amount of water in the water tank and chilled water causes larger temperature fluctuation and influences a vacuum system.
(2) In the process of continuously supplementing water and draining water, when water is just supplemented, the concentration of decomposition products in the system drainage is low, water cannot be thoroughly replaced, water is wasted greatly, and meanwhile, low-temperature water is required to be used for circulation, so that corresponding cold energy is wasted greatly.

In the description of the present utility model, it should be understood that the description of indicating the orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description and to simplify the description, rather than to indicate or imply that the apparatus or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present utility model.
In the description of the present utility model, it should be noted that, unless explicitly stated and limited otherwise, the terms "disposed," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
The technical scheme of the utility model is as follows:
referring to fig. 4, 5 and 6, the energy-saving water tank system of the water ring vacuum pump of the utility model comprises a water tank 1, a circulating water pump 2 (two pumps are connected in parallel, one pump is provided with valves at the input end and the output end of the pump), a plate heat exchanger 3 and a vacuum pump 4 which are sequentially and circularly connected through a water supply and return pipeline; the water tank 1 is internally provided with an S-shaped partition plate 11, the water tank is divided into two areas, the two separated areas are respectively and independently provided with an interface which is connected in parallel, the interface comprises a water return port 12 positioned on the side wall, a pump inlet 13, a water supplementing port 14 positioned at the top and a sewage draining port 15 positioned at the bottom, and the sewage draining port 15 is L-shaped and is convenient for piping.
The water tank 1 is connected with a water supplementing system through the water supplementing port 14 and is connected with a water draining system through the sewage draining port 15.
The S-shaped partition plate 11 is adopted, so that the heat exchange area can be enlarged, the cooling is convenient, and normal-temperature water is cooled in advance.
Compared with the original system, the utility model adds two branch parallel pipelines to the original water supplementing pipeline, the water supplying pipeline, the water returning pipeline and the water draining pipeline which are connected with the water tank, thereby forming two independent systems for switching use. Valves are arranged on the newly added branch pipe lines.
When the water tank is used, the interface of one area (an area A for short) of the water tank is closed, water circulation is carried out in the other area (an area B for short), and once the impurity concentration of the area is too high, the water tank is switched to the other area, and clean water is reused until all water is replaced.
The specific operation is as follows:
(1) Before switching, water is supplemented to the area A, the contact surface of the S-shaped partition plate is fully heat-exchanged with the area B (the area B is used for low-temperature water circulation at the moment), the heat is dissipated to the area B through the partition plate for a period of time, the temperature of the two areas after switching is ensured to be consistent, and temperature fluctuation is avoided.
(2) And when the impurity concentration of the zone B gradually rises to the highest limit value, switching to the zone A for low-temperature water circulation. At this time, the water in zone A has cooled down in advance, and the water in zone B is drained. The back and forth switching mode can be used for changing water for 1-2 times a day, so that the purposes of energy saving and water saving are achieved.
According to the utility model, the partition plates are added in the water tanks to form two independent water supplementing and waste water discharging systems, the two water tanks are switched in use, so that the water in the system can be thoroughly replaced each time, meanwhile, the cold transfer effect of the partition plates can be utilized, the circulating water temperature of the system can be fully replaced in the process of switching, and the energy and water consumption are saved. Preliminary estimation is carried out, the water consumption is saved by about 2 tons/day, and meanwhile, the cold energy of the discharged water is reduced.
