Description

Technical Field

[0001] This utility model relates to the field of steam generator technology, and specifically to a wastewater treatment device for a pure steam generator. Background Technology

[0002] A pure steam generator uses purified water as feed water and heats it with steam to produce sterile, heat-free pure steam with higher purity. During operation, the pure steam generator produces a significant amount of condensate wastewater, which can be recycled to prevent water waste. However, due to the presence of solid particulate impurities and the high temperature of this wastewater, filtration and cooling are necessary for recycling. Separating these two processes increases the footprint of the collection and treatment unit, prolongs the wastewater treatment time, and reduces recycling efficiency. Utility Model Content

[0003] This invention addresses the problem of increased wastewater treatment time and large footprint caused by separate filtration and cooling treatment of condensate wastewater generated by pure steam generators. It provides a wastewater treatment device for pure steam generators that can simultaneously filter and cool the wastewater, reducing the footprint of the wastewater treatment device, shortening the wastewater collection and treatment time, and improving the wastewater treatment and recycling efficiency.

[0004] The technical solution adopted in this utility model is:

[0005] A wastewater treatment device for a pure steam generator is provided, comprising:

[0006] The shell has a cooling chamber inside, and the outer wall of the shell has a liquid inlet and a liquid outlet that are connected to the cooling chamber. The liquid inlet is used to introduce coolant, and the liquid outlet is used to discharge coolant.

[0007] A fixing block is located on the top of the shell. A through groove is provided on the end face of the fixing block facing the top of the shell. A water inlet and a water outlet communicating with the through groove are respectively provided on the outer wall of the fixing block. An insertion hole communicating with the through groove is provided on the top of the fixing block.

[0008] A fixing plate is located on the outer top of the fixing block. A filter screen is provided on the end face of the fixing plate facing the outer top of the fixing block and inserted into the insertion hole. The outer bottom of the filter screen abuts against the outer top of the housing.

[0009] Locking components are respectively located on the outer wall surface of the fixing block and the outer wall surface of the fixing plate, and are used to lock the fixing block and the fixing plate.

[0010] Optionally, the locking assembly includes a locking block and a latch, the locking block being disposed on the outer wall surface of the fixing plate, and the latch being disposed on the outer wall surface of the fixing block, the locking block and the latch engaging with each other.

[0011] Optionally, the fixing block has a beveled surface on the outer top circumference at the socket.

[0012] Optionally, the top of the housing is provided with multiple through holes communicating with the cooling cavity, and the top of the housing is provided with a heat-conducting rod located in each through hole, with one end of each heat-conducting rod located inside the cooling cavity and the other end located inside the through groove.

[0013] Optionally, the internal cooling chambers of the housing are S-shaped.

[0014] Optionally, the liquid inlet is positioned near the water outlet, and the liquid outlet is positioned near the water inlet.

[0019] The beneficial effects of this utility model are:

[0020] 1. Coolant is introduced into the cooling chamber through the liquid inlet of the shell. After filling the cooling chamber inside the shell, it is discharged from the liquid outlet of the shell. At the same time, wastewater enters the through groove at the bottom of the fixed block through the water inlet. The wastewater flows in the through groove until it reaches the connection between the through groove and the water outlet and is discharged from the water outlet. During the flow of wastewater, the wastewater in the through groove will flow over the top of the shell. The heat contained in the wastewater will be transferred to the cooling chamber inside the shell through the top of the shell. Then the heat will be carried away by the coolant in the cooling chamber, thus completing the cooling treatment of the wastewater.

[0021] 2. By setting a fixing plate on the top of the fixing block, and setting a filter screen on the end face of the fixing plate facing the fixing block, when the fixing plate is fastened to the top of the fixing block, the filter screen on the fixing plate will enter the interior of the through groove through the insertion hole. At this time, the filter screen located inside the through groove can filter the wastewater passing through the through groove and filter out the solid particulate impurities contained in the wastewater.

[0022] 3. Locking components are installed on the outer wall of the fixing block and the outer wall of the fixing plate. The locking components can lock the fixing plate to the top of the fixing block, thereby sealing the top hole of the fixing block and preventing wastewater from overflowing through the hole and polluting the surrounding environment.

[0036] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0037] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0038] Example 1

[0039] Please see Figure 1-3 and Figure 5 As shown, this embodiment discloses a wastewater treatment device for a pure steam generator, including a housing 1. The housing 1 has a cooling chamber 10 inside. An inlet 11 and an outlet 12 connected to the cooling chamber 10 are respectively opened on the outer wall of the housing 1. The inlet 11 is used to introduce coolant, and the outlet 12 is used to discharge coolant. The coolant is supplied by an external coolant supply device. The coolant flows into the inlet 11 until the coolant fills the cooling chamber 10, and then the coolant is discharged from the outlet 12. The coolant supply device is a technology well known to those skilled in the art, and will not be described in detail here.

[0040] A fixing block 2 is provided on the top of the outer shell 1. A through groove 22 is opened on the end face of the fixing block 2 facing the top of the outer shell 1. A water inlet 20 and a water outlet 21 communicating with the through groove 22 are respectively opened on the outer wall of the fixing block 2. That is, the wastewater generated by the pure steam generator enters the interior of the through groove 22 through the water inlet 20. After flowing inside the through groove 22 for a period of time, it is discharged from the water outlet 21. During this process, the wastewater in the through groove 22 will come into contact with the top of the shell 1. The coolant in the cooling chamber 10 inside the shell 1 can exchange the heat contained in the wastewater through the top of the shell 1, so that the heat contained in the wastewater is transferred to the cooling chamber 10 through the top of the shell 1. Finally, the coolant carries away the heat, thereby achieving the cooling treatment of the wastewater. It should be noted that there can be multiple through grooves 22, which can divide the wastewater into multiple streams for treatment, thereby improving the cooling treatment effect of the wastewater. In addition, the fixing block 2 and the shell 1 are integrally molded to avoid gaps between the fixing block 2 and the shell 1, which would cause wastewater to flow out from the gaps.

[0041] A fixing plate 3 is provided on the top of the fixing block 2. The top of the fixing block 2 has an insertion hole 23 that communicates with the through groove 22. A filter screen 30 is provided on the end face of the fixing plate 3 facing the top of the fixing block 2. When the fixing plate 3 is fastened to the top of the fixing block 2, the filter screen 30 can be inserted into the insertion hole 23 and finally the filter screen 30 is located inside the through groove 22. It is worth noting that the bottom of the filter screen 30 located inside the through groove 22 abuts against the top of the housing 1. Since the filter screen 30 is used to filter the wastewater entering the through groove 22, if there is a gap between the filter screen 30 and the top of the housing 1, some wastewater will be discharged from the outlet 21 at the other end of the fixing block 2 without being filtered by the filter screen 30, so that the wastewater after filtration will still contain a lot of solid particulate impurities.

[0042] Locking components are provided on the outer wall of the fixing block 2 and the outer wall of the fixing plate 3. The locking components can lock the fixing plate 3 on the outer top of the fixing block 2, so that the insertion hole 23 on the top of the fixing block 2 is sealed by the fixing plate 3, preventing wastewater from overflowing from the insertion hole 23 and affecting the surrounding environment. Specifically, in this embodiment, the locking components include a locking block 6 and a buckle 5. The locking block 6 is provided on the outer wall of the fixing plate 3, and the buckle 5 is provided on the outer wall of the fixing block 2. When the fixing plate 3 is fastened to the top of the fixing block 2, the locking block 6 and the buckle 5 can be fastened to the outer top of the fixing block 2, so that the insertion hole 23 on the top of the fixing block 2 is sealed by the fixing plate 3, preventing wastewater from overflowing from the insertion hole 23.

[0043] Example 2

[0044] This embodiment is a further optimization based on Embodiment 1. For details, please refer to [link / reference needed]. Figure 4 As shown, the cooling chamber 10 inside the casing 1 is generally S-shaped. The inlet 11, which communicates with the cooling chamber 10, is located near the outlet 21, and the outlet 12, which communicates with the cooling chamber 10, is located near the inlet 20. That is, the coolant flowing into the cooling chamber 10 through the inlet 11 flows from the side near the outlet 21 towards the inlet 20, and finally exits from the outlet 12. During the coolant flow, the coolant carries away heat from the wastewater in the opposite direction of the wastewater flow. Compared to the coolant flowing towards the wastewater, flowing in the opposite direction allows for faster heat removal from the wastewater. Furthermore, simply filling the cooling chamber 10 with coolant for heat exchange with the wastewater can easily lead to heat accumulation in the coolant within the cooling chamber 10, reducing the heat exchange efficiency. The S-shaped distribution of the cooling chamber 10 is more conducive to heat removal.

[0045] Example 3

[0046] This embodiment is a further optimization based on Embodiment 1. For details, please refer to [link / reference needed]. Figure 1 and Figure 2 As shown, a circumferentially inclined surface 24 is provided on the outer top end face of the fixing block 2 at the insertion hole 23. When the fixing plate 3, which is locked to the outer top of the fixing block 2 by the locking assembly, is removed, the wastewater flows in the through groove 22, and the through groove 22 and the insertion hole 23 are connected. The insertion hole 23 is covered and sealed by the fixing plate 3. As the wastewater flows for a long time, a small amount of wastewater will leak out from the gap between the insertion hole 23 and the filter screen 30. The leaked wastewater will accumulate on the outer top inclined surface 24 of the fixing block 2. After the fixing plate 3 is opened, the wastewater accumulated on the inclined surface 24 can flow from the insertion hole 23 into the through groove 22 after the filter screen 30 is removed from the insertion hole 23, thus preventing the wastewater from accumulating on the top of the fixing block 2 and affecting the subsequent use of the fixing block 2 and the fixing plate 3.

[0047] A pressure block 31 is provided between the bottom end face of the fixing plate 3 and the filter screen 30. The end face of the pressure block 31 facing the fixing block 2 is adapted to the inclined surface 24. That is, when the fixing plate 3 is locked to the top of the fixing block 2 by the locking assembly, the filter screen 30 is inserted into the inside of the through groove 22 through the insertion hole 23. There is a space between the filter screen 30 and the inclined surface 24 that can collect a small amount of overflowing wastewater. The pressure block 31 is located in this space and can seal the space to prevent wastewater from overflowing to the top of the fixing block 2.

[0048] A sealing gasket (not shown in the figure) is provided on the closed surface of the pressure block 31 facing the fixing block 2 to enhance the sealing effect at the socket 23 and prevent wastewater from overflowing from the socket 23. In addition, a handle 7 is provided on the outer top of the fixing plate 3 so that the user can hold the handle 7 to remove the fixing plate 3 from the top of the fixing block 2.

[0049] In this embodiment, wastewater flows in the channel 22 for a long time, and some solid particles and impurities will adhere to the inner wall of the channel 22 to form scale, which will affect the flow of wastewater over time. To address this, a fixing strip 4 is provided on the outer wall of the housing 1, and a storage cavity 40 is opened inside the fixing strip 4. A cleaning rod 41 is placed inside the storage cavity 40. When it is necessary to clean the inside of the channel 22 and the outer top of the fixing block 2, the cleaning rod 41 located in the storage cavity 40 of the fixing strip 4 can be taken out, and then the cleaning rod 41 is inserted into the inside of the channel 22 for cleaning. After cleaning is completed, the cleaning rod 41 is put back into the storage cavity 40 of the fixing strip 4 for storage until the next time the channel 22 needs to be cleaned, at which point the cleaning rod 41 can be taken out.

[0050] Multiple through holes 13 connected to the cooling chamber 10 are opened on the top of the shell 1. All through holes 13 are located inside the same through groove 22. A heat-conducting rod 14 is installed inside each through hole 13. The heat-conducting rod 14 is sealed to the through hole 13. One end of each heat-conducting rod 14 is located inside the through groove 22, and the other end is located inside the cooling chamber 10. When the cooling chamber 10 is filled with coolant and wastewater is flowing in the through groove 22, the heat in the wastewater can be transferred through the heat-conducting rod 14. The heat-conducting rod 14 transfers the heat in the wastewater to the coolant, and finally the coolant carries away the heat on the heat-conducting rod 14.

[0051] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Without conflict, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
