Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in the field without creative work are all within the scope of protection of the present invention.

[0024] See also Figure 1 as well as Figure 2As shown, this embodiment discloses a wastewater evaporation device, including a condenser 101, a sealing structure and an anti-corrosion structure.

The sealing groove 104 is arranged at the connection between the water outlet 103 and the pipeline. The sealing gasket 105 is used to be installed inside the sealing groove 104. After the water outlet 103 and the pipeline are connected, the sealing gasket 105 is used to squeeze the sealing gasket 105 so that the connection between the water outlet 103 and the pipeline is sealed; the anti-corrosion structure includes: two mounting rings 106 and an anti-corrosion plate 107. The two mounting rings 106 are respectively mounted on the inner walls of the water outlet 103 and the pipeline. The anti-corrosion plate 107 is mounted between the two mounting rings 106. The outer wall of the anti-corrosion plate 107 is used to cover the connection between the water outlet 103 and the pipeline.

[0026] Among them, a closed ring 108 is arranged on the mounting ring 106 located on the water outlet 103, and the lower end surface of the closed ring 108 is an inclined surface;

[0027] The present invention mainly includes a condenser 101, a sealing structure and an anti-corrosion structure. In actual use, wastewater enters the condenser 101 from the water inlet 102, is heated to an evaporation state, and the generated steam is cooled and condensed into liquid water in the condenser 101, and then discharged through the water outlet 103. In order to ensure the sealing of the device, the water outlet 103 and the pipeline are detachably connected, and the sealing groove 104 and the sealing gasket 105 are located at the connection. The sealing gasket 105 is squeezed to form a seal to prevent liquid leakage. In addition, the anti-corrosion structure is composed of two mounting rings 106 and an anti-corrosion plate 107 installed on the water outlet 103 and the inner wall of the pipeline. The anti-corrosion plate 107 covers the outer wall of the connection, thereby protecting the connection from corrosion and ensuring the long-term stable operation of the device.

[0028] In some embodiments, the water outlet 103 and the ends of the pipeline are flange structures.

[0029] In actual use, the flange structure can make it easier to disassemble and assemble the water outlet 103 and the pipeline.

[0030] In some embodiments, a threaded hole 109 with continuous threads is provided on the flange structure, and a bolt 110 is provided on the internal thread of the threaded hole 109 .

[0031] In actual use, the flange structure is locked by the cooperation of a plurality of bolts 110 and threaded holes 109 .

[0032] In some embodiments, there are four sealing grooves 104 , which are all arranged on the flange structure. The four sealing grooves 104 are interlocked in pairs to form two sealing holes 111 , and the sealing gasket 105 is used to be installed inside the sealing hole 111 .

[0033] In actual use, the two sealing holes 111 are provided to form a secondary seal, so that the sealing performance between the flange structures is better.

[0034] In some embodiments, the water outlet 103 and the end of the pipeline have chamfers 112. When the water outlet 103 is buckled with the pipeline, the two chamfers 112 form a sealing area 113. A filling ring 114 is provided on the outer wall of the anti-corrosion plate 107. The filling ring 114 is used to be installed in the sealing area 113 and fit tightly with the sealing area 113.

[0035] During actual use, the chamfer 112 at the water outlet 103 and the end of the pipeline is two inclined surfaces, which are buckled together to form a sealing area 113 with a triangular cross-section, and is filled through the filling ring 114 on the outer wall of the anti-corrosion plate 107, so that the connection between the water outlet 103 and the pipeline is filled, preventing liquid from entering the sealing hole 111 from the gap between the water outlet 103 and the pipeline to corrode the sealing gasket 105, thereby effectively protecting the sealing gasket 105.

[0036] In some embodiments, the two mounting rings 106 are arranged to be tilted toward each other.

[0037] During actual use, the mounting ring 106 located on the water outlet 103 is tilted downward, and the mounting ring 106 located on the pipeline is tilted upward. The two mounting rings 106 are arranged opposite to each other. The purpose of this arrangement is to form an installation area between the two mounting rings 106 to facilitate the installation of the anti-corrosion plate 107.

[0038] In some embodiments, the sealing holes 111 are located on both sides of the bolt 110 .

[0039] In actual use, the purpose of setting on both sides of the bolt 110 is to make the distance between the two sealing holes 111 and the bolt 110 closer, so that after the bolt 110 and the threaded hole 109 cooperate, the sealing gasket 105 in the sealing hole 111 can be pressed more firmly.

[0040] In some embodiments, the condenser 101 is further provided with a cold water inlet 115 and a hot water outlet 116 , the cold water inlet 115 is connected to a low-temperature water pool 117 through a pipeline, and the hot water inlet is connected to a high-temperature water pool 118 through a pipeline.

[0041] In actual use, the high-temperature water tank 118 is used to pass high-temperature hot water into the hot water inlet for use, and the low-temperature water tank 117 is used to pass low-temperature water into the cold water inlet 115 for use.

[0042] In some embodiments, the wastewater evaporation device further includes a wastewater tank 119, a wastewater mother liquor tank 120, a centrifugal high-level tank 121, a waste residue centrifuge 122, a feed high-level tank 123, a wastewater evaporator 126, a heater 124, and a hot water tank 125;

[0043] Among them, the wastewater tank 119, the wastewater mother liquid tank 120, the hot water tank 125, the condensed water tank, the low-temperature water pool 117 and the high-temperature water pool 118 are all arranged on the ground, the waste residue centrifuge 122 is arranged at a height of 5m from the ground, the centrifugal high-level tank 121, the feed high-level tank 123, the wastewater evaporator 126 and the condenser 101 are all arranged at a height of 10m from the ground;

[0044] The outlet end of the wastewater tank 119 is connected to the inlet end of the feed high-level tank 123 through a pipeline, the outlet end of the feed high-level tank 123 is connected to the wastewater inlet end of the wastewater evaporator 126, the outlet 103 of the wastewater evaporator 126 is connected to the inlet end of the heater 124 through a pipeline, the outlet end of the heater 124 is connected to the water inlet 102 of the wastewater evaporator 126 through a pipeline, the pipeline between the inlet end of the heater 124 and the outlet end of the wastewater evaporator 126 is connected to the inlet end of the centrifugal high-level tank 121 through a discharge pump, and the inlet end of the feed high-level tank 123 is connected to the inlet end of the centrifugal high-level tank 121. The outlet end is also connected to the centrifugal high-level tank 121 through a pipeline, the outlet end of the centrifugal high-level tank 121 is connected to the inlet end of the waste residue centrifuge 122 through a pipeline, the waste residue centrifuge 122 is connected to the wastewater mother liquor tank 120 through a pipeline, the discharge end of the wastewater mother liquor tank 120 is connected to the inlet end of the feed high-level tank 123 through a mother liquor recovery pump, and the outlet end of the feed high-level tank 123 is also connected to the inlet end of the wastewater mother liquor tank 120 through a pipeline; an exhaust port is provided on the wastewater evaporator 126, and the exhaust port is connected to the condenser 101; the exhaust port of the condenser 101 is connected to the vacuum pump.

[0045] In actual use, the staff pumps the wastewater in the wastewater tank 119 into the feed high-level tank 123 through the wastewater transfer pump. The feed high-level tank 123 performs preliminary storage of the wastewater, and then passes the wastewater into the wastewater evaporator 126. At this time, the vacuum pump is turned on, and the vacuum pump evacuates the wastewater evaporator 126 to allow the inside of the wastewater evaporator 126 to perform vacuum and low-temperature evaporation. This is why the wastewater evaporator 126 is set at a height of 10m, because the pipeline between the inlet of the heater 124 and the outlet of the wastewater evaporator 126 needs to be long enough to support the vacuum negative pressure and low-temperature evaporation of the wastewater evaporator 126. After the wastewater passes through the heater 124, it circulates into the wastewater evaporator 126. Evaporation is performed, and the wastewater evaporator 126 generates steam and condensed water during the evaporation process, which are passed into the condenser 101 through a pipeline. The condenser 101 discharges the condensed water into the condensation water tank for collection through the heat exchange of the low-temperature water pool 117 and the high-temperature water pool 118; during the evaporation of the wastewater, the residual liquid enters the centrifugal high-level tank 121 through the discharge pump for temporary storage, and then enters the waste residue centrifuge 122 for solid-liquid separation, and the solid waste is classified and processed, and the liquid is passed into the wastewater mother liquor tank 120. In order to reduce the residual solids in the wastewater mother liquor tank 120, it is necessary to repeatedly centrifuge the wastewater in the wastewater mother liquor tank 120, and finally the wastewater mother liquor tank 120 recovers the waste liquid to complete the overall evaporation of the wastewater.
