Description

[Technical Field]

[0001] This invention relates to a water deodorizer, and more particularly to a water deodorizer that can achieve energy-saving effects and full automation. [Previous Technology]

[0002] In the process equipment of general dyeing and finishing plants or boiler plants, steam is used and the steam passes through heat exchangers. When the temperature of the heat exchanger drops, condensate is formed. At this time, a dewatering device is used to automatically remove the condensate and air from the system. The dewatering device can form a water film on the inner surface of the condensate recovery pipeline, thereby reducing the heat loss of the pipeline and keeping the steam in the steam pipeline and process equipment in the driest state, so that the steam surface has the best heat transfer rate and maintains good steam quality.

[0003] In conventional technology, water separators typically use float-type, orifice-type, or inverted-bucket-type water separators. However, both float-type and inverted-bucket-type water separators generally introduce steam when discharging condensate, resulting in energy loss. Furthermore, with orifice-type water separators, if the orifice is too small, the drainage volume is insufficient, reducing the amount of steam entering the heat exchanger and thus decreasing heating efficiency; conversely, if the orifice is too large, excessive steam loss will prevent energy saving.

[0004] On the other hand, Figure 9 is a schematic diagram illustrating the structure of the buffer tank in the prior art. Referring to Figure 9, in the prior art, both the inverted bucket type water separator and the float type water separator are installed at a position of about 50 centimeters above the ground. In the structure of the inverted bucket type water separator or the float type water separator, an additional buffer tank 903 needs to be installed at the condensate pipe 901 used for drainage. Only in this way can the condensate be pushed up to a condensate drain pipe five meters high through the pipe 905, and then discharged back to the boiler for use. Such a structure makes the water separator too bulky, its installation location too restricted, and it cannot achieve the effect of energy saving and carbon reduction. [Summary of the Invention]

[0005] [Problem to be Solved by the Invention] As can be seen from the prior art described above, current water purifier structures all have their drawbacks, thus failing to achieve the effects of energy saving, carbon reduction, and size reduction. Therefore, there is a need to provide a water purifier that can simultaneously achieve energy saving and fully automatic drainage.

[0006] [Technical Means for Solving the Problem] An energy-saving fully automatic water dewatering device includes: a storage tank, including a water inlet and a water outlet; a water inlet pipe disposed at the water inlet, and a portion of the water inlet pipe disposed in the storage tank; a water outlet pipe disposed at the water outlet, and a portion of the water outlet pipe disposed in the storage tank; a valve device connected to another portion of the water outlet pipe; and at least one high water level sensor disposed on a top surface of the storage tank; wherein the valve device is electrically connected to at least one of the high water level sensors, and wherein the length of the portion of the water outlet pipe disposed in the storage tank is greater than the length of the portion of the water inlet pipe disposed in the storage tank.

[0007] On the other hand, the energy-saving fully automatic water dewatering device of the present invention further includes at least one low water level sensor, at least one of the low water level sensors is disposed on the top surface of the storage tank, and the valve device is electrically connected to at least one of the low water level sensors.

[0008] Preferably, the inlet pipe is connected to the drain pipe, and a baffle is included between the inlet pipe and the drain pipe.

[0009] Preferably, there are multiple high water level sensors, which are disposed on the top surface of the storage tank and electrically connected to the valve device.

[0010] Preferably, there are multiple low water level sensors, which are disposed on the top surface of the storage tank and electrically connected to the valve device.

[0011] Preferably, the number of high water level sensors and the number of low water level sensors are both multiple, the high water level sensors and the low water level sensors are disposed on the top surface of the storage tank, and the high water level sensors and the low water level sensors are electrically connected to the valve device.

[0012] Furthermore, the present invention also provides another energy-saving fully automatic dewatering device, comprising: a storage tank, including a water inlet and a water outlet; a water inlet pipe disposed at the water inlet, and a portion of the water inlet pipe disposed in the storage tank, the other portion of the water inlet pipe including an inlet section; a water outlet pipe disposed at the water outlet, and a portion of the water outlet pipe disposed in the storage tank; a valve device connected to the other portion of the water outlet pipe; a pressure balancing pipe, one end of the pressure balancing pipe disposed on a top surface of the storage tank, the other end of the pressure balancing pipe disposed in the storage tank; and a float level controller, one end of the float level controller disposed in the storage tank, the other end of the float level controller disposed on the top surface of the storage tank; wherein the valve device is electrically connected to the float level controller, wherein the length of the portion of the water outlet pipe disposed in the storage tank is greater than the length of the portion of the water inlet pipe disposed in the storage tank.

[0013] Preferably, the storage tank further includes a drain valve and / or a drain cleaning valve, the drain valve being disposed on a bottom of an outer wall of the storage tank and the drain cleaning valve being disposed on a bottom surface of the storage tank.

[0014] Preferably, the inlet pipe further includes a filter screen disposed in the inlet section.

[0015] Preferably, the inlet pipe further includes a nozzle disposed at an outlet of the inlet section.

[0016] [Effects of the Invention] The present invention provides an energy-saving fully automatic water dewatering device. The energy-saving fully automatic water dewatering device of the present invention has the following advantages and effects: Because the energy-saving fully automatic water dewatering device of the present invention includes a water level sensor, some condensate will accumulate below the storage tank and form a water wall. In this way, the steam in the storage tank cannot penetrate the water wall and be discharged from the drain pipe. The present invention allows the storage tank to discharge only condensate, achieving the best energy-saving and carbon-reducing level of the water dewatering device.

Implementation Method

[0017] The embodiments of the present invention will be described in more detail below with reference to the drawings and component symbols, so that those skilled in the art can implement them after reading this specification.

[0018] Figure 1 is a schematic diagram illustrating the structure of an energy-saving fully automatic water dewatering device according to an embodiment of the present invention. Referring to Figure 1, an embodiment of the present invention provides an energy-saving fully automatic water dewatering device 1, which includes a storage tank 10, an inlet pipe 20, a drain pipe 30, a valve device 40, and at least one high water level sensor 50. The storage tank 10 includes an inlet 101 and a drain outlet 103, and the storage tank 10 includes a height H10. The inlet pipe 20 is disposed at the inlet 101, and a portion of the inlet pipe 20 is disposed in the storage tank 10. The drain pipe 30 is disposed at the drain outlet 103, and a portion of the drain pipe 30 is disposed in the storage tank 10. The valve device 40 is connected to another portion of the drain pipe 30, wherein the valve device 40 may be a stainless steel electric ball valve, a solenoid valve, or other types of valve. A high water level sensor 50 is disposed on a top surface S1 of the storage tank 10. In one embodiment of the present invention, the high water level sensor 50 is a probe-type water level sensor, and the probe falls at a first height H50. It should be understood that in other embodiments of the present invention, the high water level sensor 50 may be other types of sensors, such as ultrasonic, electrode, pressure, capacitive, or other types of sensors. By means of the structure of the above-described energy-saving fully automatic water drainer 1, the present invention can achieve the effects of energy saving and carbon reduction, volume reduction, and fully automatic drainage. One embodiment of the present invention will be described in detail below. The number of high water level sensors 50 is not limited to the one shown in FIG. 1, but can be set to one or more as needed to avoid the failure of one of them.

[0019] In detail, when the water level in the storage tank 10 reaches the first height H50 of the detection level and is detected by the high water level sensor 50, the high water level sensor 50 will trigger and open the valve device 40. At this time, the water in the storage tank 10 will be discharged from the inlet of the drain pipe 30 located at the bottom of the storage tank 10 due to pressure. When the water level is lower than the detection height of the high water level sensor 50, the high water level sensor 50 will delay for 3-5 seconds before closing the valve device 40. In other words, when the high water level sensor 50 does not detect water, it will delay for 3-5 seconds before closing the valve device 40 to further discharge excess water and keep the water in the storage tank 10 at 3-5 / 10 full, so as to form a water seal (water wall) by using the 3-5 / 10 full water to prevent the steam in the storage tank 10 from penetrating the water wall and being discharged from the drain pipe 30. This invention allows the storage tank 10 to discharge only condensate, achieving optimal energy saving and carbon reduction for the dewatering device. Therefore, the energy-saving fully automatic dewatering device 1 of this invention can achieve fully automatic drainage using only the high water level sensor 50.

[0020] Figure 2 is a schematic diagram illustrating the structure of an energy-saving fully automatic water dewatering device according to another embodiment of the present invention. Referring to Figure 2, in another embodiment of the present invention, the energy-saving fully automatic water dewatering device 2 has a structure that is basically the same as that of the energy-saving fully automatic water dewatering device 1 in Figure 1, except that the energy-saving fully automatic water dewatering device 2 further includes at least one low water level sensor 60, which is disposed on the top surface S1 of the storage tank 10, and the valve device 40 is electrically connected to the at least one low water level sensor 60. In one embodiment of the present invention, the low water level sensor 60 can also be a probe-type water level sensor, and the probe falls at a second height H60. It should be understood that in other embodiments of the present invention, the low water level sensor 60 can be other types of sensors, such as ultrasonic, electrode, pressure, capacitive, or other types of sensors.

[0021] The valve device 40 is electrically connected to the high water level sensor 50 and the low water level sensor 60 to automatically open the valve device 40 by detecting the water level. The height H10 of the storage tank 10 is greater than the first height H50, and the first height H50 is greater than the second height H60. Furthermore, the length H30 of the drain pipe 30 installed in the storage tank 10 is greater than the length H20 of the inlet pipe 20 installed in the storage tank 10. With the above-described structure of the energy-saving fully automatic water dewatering device 2, the present invention achieves the effects of energy saving and carbon reduction, simplified size, and fully automatic drainage. Another embodiment of the present invention will be described in detail below.

[0022] Figure 3 is a schematic diagram illustrating the structure of an energy-saving fully automatic water dewatering device at a low water level in another embodiment of the present invention. Referring to Figure 3, in another embodiment of the present invention, when the condensate W is at a low water level, the valve device 40 will be closed. At this time, condensate W will begin to accumulate below the low water level sensor 60. The condensate W will not be automatically discharged but will accumulate below the storage tank 10. Since the inlet of the drain pipe 30 is located at the bottom of the storage tank 10, the condensate W accumulated below the storage tank 10 will form a water wall. The steam S cannot penetrate the water wall and be discharged from the drain pipe 30. This avoids the phenomenon of energy loss caused by the steam S being discharged with the condensate in the prior art.

[0023] Figure 4 is a schematic diagram illustrating the structure of an energy-saving fully automatic water dewatering device at a high water level in an embodiment of the present invention. Referring to Figure 4, when the condensate W in the storage tank 10 accumulates to the detection level of the high water level sensor 50, the high water level sensor 50 will trigger and open the valve device 40. At this time, the condensate W will be discharged outward from the inlet of the drain pipe 30 located at the bottom of the storage tank 10 due to pressure. When the level of the condensate W is discharged to the detection level of the low water level sensor 60, the low water level sensor 60 will trigger and close the valve device 40. At this time, due to the setting and detection position of the low water level sensor 60, a portion of condensate W remains below the low water level sensor 60. The amount of this portion of condensate W is approximately 30% to 50% of the water volume in the storage tank 10, as shown in Figure 3 (the 50% water volume is not shown in the figure). Meanwhile, the condensate W accumulated below the storage tank 10 forms a water wall, preventing steam S from penetrating the water wall and being discharged through the drain pipe 30. This invention allows the storage tank 10 to discharge only the condensate W, achieving the optimal energy-saving and carbon-reducing level of the dewatering device. Therefore, the energy-saving fully automatic dewatering device 2 of this invention achieves fully automatic drainage through a high water level sensor 50 and a low water level sensor 60.

[0024] On the other hand, in the above embodiments of the present invention, the size of the storage tank 10 can be set according to the amount of steam S and condensate W, and the drainage volume of condensate W can be set according to the heat transfer area of ​​various heat exchangers. The drainage volume of condensate W can also be adjusted by adjusting the positions of the high water level sensor 50 and the low water level sensor 60.

[0025] In addition, in one embodiment of the present invention, another part of the water inlet pipe 20 may be connected to a pipeline of an air compressor, a separator, a dryer, a boiler or a filter, and the valve device 40 may be connected to a pipeline of a water storage tank, an air compressor, a separator, a dryer, a boiler or a filter through a pipeline, so that the condensate W can be recycled.

[0026] Figure 5 is a schematic diagram illustrating the structure of an energy-saving fully automatic water purifier according to another embodiment of the present invention. Referring to Figures 2 and 5, in some embodiments of the present invention, the inlet pipe 20 and the drain pipe 30 are set separately, as shown in Figures 1 and 2. However, in another embodiment of the present invention, the inlet pipe 20 can be connected to the drain pipe 30, and a baffle plate 70 is included between the inlet pipe 20 and the drain pipe 30, as shown in Figure 5. Connecting the inlet pipe 20 to the drain pipe 30 can further enhance the structural strength of the inlet pipe 20 and the drain pipe 30.

[0027] Furthermore, referring to Figure 5 again, in another embodiment of the present invention, an energy-saving fully automatic water dewatering device 3 with a different structure is provided. In the energy-saving fully automatic water dewatering device 3, the number of high water level sensors 50 can be multiple, such as high water level sensors 50 and 501. Both high water level sensors 50 and 501 are disposed on the top surface S1 of the storage tank 10, and both high water level sensors 50 and 501 are electrically connected to the valve device 40. Setting the number of high water level sensors 50 to multiple can achieve the effect of preventing the energy-saving fully automatic water dewatering device 3 from losing the ability to detect water level due to the failure of one of the sensors. It should be understood that the number of high water level sensors 50 is not limited to the two shown in Figure 5, but can be set to two or more as needed.

[0028] Furthermore, referring to Figure 5 again, similarly, in the energy-saving fully automatic water dewatering device 3, the number of low water level sensors 60 can be multiple, such as low water level sensors 60 and 601. Both low water level sensors 60 and 601 are disposed on the top surface S1 of the storage tank 10, and both are electrically connected to the valve device 40. Setting the number of low water level sensors 60 to multiple can prevent the energy-saving fully automatic water dewatering device 3 from losing its ability to detect water levels due to the failure of one sensor. It should be understood that the number of low water level sensors 60 is not limited to the two shown in Figure 5, but can be set to two or more as needed.

[0029] In the embodiments of the present invention, the number of high water level sensors 50 may be set to a plurality, or the number of low water level sensors 60 may be set to a plurality, or both the number of high water level sensors 50 and the number of low water level sensors 60 may be set to a plurality.

[0030] Figure 6 is a schematic diagram illustrating the structure of an energy-saving fully automatic water dewatering device according to another embodiment of the present invention; Figure 7 is a perspective schematic diagram illustrating the structure of an energy-saving fully automatic water dewatering device according to another embodiment of the present invention; Figure 8 is a side perspective schematic diagram illustrating the structure of an energy-saving fully automatic water dewatering device according to another embodiment of the present invention. Referring to Figures 6 to 8, in another embodiment of the present invention, an energy-saving fully automatic water dewatering device 4 is provided, including: a storage tank 10, a water inlet pipe 20, a drain pipe 30, a valve device 40, a pressure balancing pipe 80, and a float water level controller 1000.

[0031] The storage tank 10 includes an inlet 101, a drain 103, a top surface S1, and a bottom surface S2. An inlet pipe 20 is disposed at the inlet 101, with a portion of the inlet pipe 20 disposed within the storage tank 10, and the other portion of the inlet pipe 20 including an inlet section 201. A drain pipe 30 is disposed at the drain 103, with a portion of the drain pipe 30 disposed within the storage tank 10. A valve device 40 is connected to the other portion of the drain pipe 30. One end of a pressure balancing pipe 80 is disposed on the top surface S1 of the storage tank 10, and the other end of the pressure balancing pipe 80 is disposed within the storage tank 10. One end of a float level controller 1000, i.e., the float 1001, is disposed within the storage tank 10, and the other end of the float level controller 1000, i.e., the fixed body 1003, is disposed on the top surface S1 of the storage tank 10. The valve device 40 is electrically connected to the float level controller 1000, and the length H30 of the drain pipe 30 in the storage tank 10 is greater than the length H20 of the inlet pipe 20 in the storage tank 10. Furthermore, it should be understood that although two floats 1001 are shown in Figures 7 and 8, they are actually two floats 1001 at different heights to correspond to different water levels. In reality, the float level controller 1000 in the energy-saving fully automatic water dewatering device 4 only includes one float 1001.

[0032] The operation of the energy-saving fully automatic water dewatering device 4 is roughly the same as in the above embodiment. Condensate enters the storage tank 10 through the inlet section 201 and the inlet pipe 20. The pressure balancing pipe 80 balances the pressure of the condensate in the storage tank 10 to stabilize the water level. As the water level of the condensate in the storage tank 10 continues to rise, the float 1001 also rises. When the water level reaches level W1, that is, when the float 1001 reaches the high point of the float level controller 1000, the valve device 40 will be automatically triggered and opened. Then, due to pressure, the condensate will be discharged from the inlet of the drain pipe 30 located at the bottom of the storage tank 10. When the water level of the condensate is discharged to level W2, that is, when the float 1001 reaches the low point of the float level controller 1000, the valve device 40 will be automatically triggered and closed. At this time, more than 40% of the condensate remains in the storage tank 10, forming a water wall to stop the steam discharge and achieve a super energy-saving effect.

[0033] Referring again to Figures 6 to 8, in another embodiment of the present invention, the storage tank 10 further includes a drain valve 105 and / or a drain cleaning valve 107. The drain valve 105 is disposed on the bottom of an outer wall 109 of the storage tank 10, and the drain cleaning valve 107 is disposed on a bottom surface S2 of the storage tank 10. The drain valve 105 can drain all the condensate in the storage tank 10, while the drain cleaning valve 107 can drain the sewage and dirt deposited at the bottom of the storage tank 10, thereby achieving the effect of cleaning the storage tank 10.

[0034] Furthermore, in another embodiment of the present invention, the inlet pipe 20 further includes a filter screen 203, which is disposed in the inlet section 201 to filter the condensate entering the storage tank 10. Furthermore, the inlet pipe 20 may further include a nozzle 205, which is disposed at an outlet of the inlet section 201. Different types of nozzles 205 can be used to adjust the flow rate of the condensate. It should be understood that the energy-saving fully automatic water dewatering device 4 may include both the filter screen 203 and the nozzle 205, or it may include only the filter screen 203, or only the nozzle 205. Furthermore, the energy-saving fully automatic water dewatering device 4 may also include a drain valve 105, a drain cleaning valve 107, a filter screen 203, and a nozzle 205, or these four components may be arbitrarily combined. In other words, the drain valve 105, drain cleaning valve 107, filter screen 203 and nozzle 205 can be selectively installed according to the user's actual needs.

[0035] As can be seen from the above description of the present invention, the present invention provides an energy-saving fully automatic water dewatering device. The energy-saving fully automatic water dewatering device of the present invention has the following advantages: 1. The storage tank capacity of the energy-saving fully automatic water dewatering device of the present invention is more than six times larger than that of other types of water dewatering devices, and it can include the function and effect of the buffer tank in the prior art. Therefore, there is no need to connect an external buffer tank, so that the external size is similar to that of the traditional inverted tank type water dewatering device and the purpose of volume reduction can be achieved. 2. The drainage volume of condensate can be set according to the heat transfer area of ​​various heat exchangers. 3. The size of the storage tank can be set according to the amount of steam and condensate, and the discharge volume of condensate can be controlled by the difference between high and low water levels, so as to achieve no steam emission and thus achieve the effect of energy saving and carbon reduction. 4. The energy-saving fully automatic water dewatering device of the present invention can use the function of a water level sensor to allow some condensate to accumulate below the storage tank and form a water wall. In this way, the steam in the storage tank cannot penetrate the water wall and be discharged from the drain pipe. The present invention allows the storage tank to discharge only condensate, achieving the best energy-saving and carbon-reducing level of the water dewatering device, and avoiding the problem of wasted steam discharge caused by fine sand, debris, or component damage in ordinary water dewatering devices.
