Technical Field
[0001] This utility model relates to the field of wastewater evaporation technology, specifically to a wastewater evaporation device. Background Technology
[0002] Wastewater evaporation technology is an effective method widely used in industrial and municipal wastewater treatment. Its core principle is to evaporate water from wastewater through heating, leaving behind concentrated pollutants, thereby reducing the volume and toxicity of the wastewater. This technology is particularly suitable for treating high-concentration, toxic, harmful, and difficult-to-degrade wastewater, such as wastewater from the chemical, pharmaceutical, and textile industries. The evaporation process not only significantly reduces the pollution load but also allows for the recovery of valuable resources, such as salts and metal ions, through wastewater concentration and crystallization. Therefore, wastewater evaporation technology has significant application value in achieving environmental protection and resource recovery.

[0004] The specification of prior art 1 discloses a novel flange sealing connection device. In use, the inner sealing ring and the inner ring groove, as well as the outer sealing ring and the outer ring groove, form a secondary seal for the flange, thereby improving the sealing performance of the flange. However, in actual applications, due to the gap between the two flanges, the sealing ring will be corroded during the service life, leading to the failure of the sealing ring and consequently causing water leakage between the two flanges. Summary of the Invention

Detailed Implementation
[0023] The present invention will be further described below with reference to the embodiments. The described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.
[0024] Please see Figure 1 as well as Figure 2As shown, this embodiment discloses a wastewater evaporation device, including a condenser 101, a sealing structure and a corrosion-resistant structure. The condenser 101 has a water inlet 102 and a water outlet 103, and the water outlet 103 is connected to a condensate tank through a pipeline.
[0025] The sealing structure includes a sealing groove 104 and a sealing gasket 105. The outlet 103 and the connection of the pipeline are detachably connected. The sealing groove 104 is set at the connection of the outlet 103 and the pipeline. The sealing gasket 105 is installed inside the sealing groove 104. After the outlet 103 and the pipeline are connected, the sealing gasket 105 is squeezed to form a seal at the connection of the outlet 103 and the pipeline. The anti-corrosion structure includes two mounting rings 106 and an anti-corrosion plate 107. The two mounting rings 106 are respectively installed on the inner wall of the outlet 103 and the pipeline. The anti-corrosion plate 107 is installed between the two mounting rings 106. The outer wall of the anti-corrosion plate 107 is used to cover the connection of the outlet 103 and the pipeline.
[0026] Among them, a sealing ring 108 is provided on the mounting ring 106 located on the outlet 103, and the lower end face of the sealing ring 108 is a slope.
[0027] This utility model mainly includes a condenser 101, a sealing structure, and a corrosion-resistant structure. In actual use, wastewater enters the condenser 101 through the inlet 102, is heated to an evaporating state, and the generated steam is cooled and condensed into liquid water within the condenser 101, then discharged through the outlet 103. To ensure the device's airtightness, the outlet 103 is detachably connected to the pipeline. A sealing groove 104 and a sealing gasket 105 are located at the connection point. The sealing gasket 105 is compressed to form a seal, preventing liquid leakage. Furthermore, the corrosion-resistant structure consists of two mounting rings 106 installed on the outlet 103 and the inner wall of the pipeline, and an anti-corrosion plate 107. The anti-corrosion plate 107 covers the outer wall of the connection point, thereby protecting the connection point from corrosion and ensuring the long-term stable operation of the device.
[0028] In some embodiments, the outlet 103 and the end of the pipe are both flange structures.
[0029] In actual use, the flange structure makes it easier to assemble and disassemble the outlet 103 from the pipeline.
[0030] In some embodiments, the flange structure is provided with a threaded hole 109 with continuous threads, and a bolt 110 is provided inside the threaded hole 109.
[0031] In actual use, the flange structure is locked by a combination of several bolts 110 and threaded holes 109.
[0032] In some embodiments, there are four sealing grooves 104, all of which are provided on the flange structure. The four sealing grooves 104 interlock to form two sealing holes 111, and the sealing gasket 105 is used to be installed inside the sealing holes 111.
[0033] In actual use, the purpose of setting two sealing holes 111 is to form a secondary seal, which makes the sealing performance between the flange structures better.
[0034] In some embodiments, the outlet 103 and the end of the pipe have chamfers 112. When the outlet 103 is engaged with the pipe, 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 fits tightly against the sealing area 113.
[0035] In actual use, the chamfer 112 at the end of the outlet 103 and the pipe is two bevels. After the two bevels are joined together, a sealing area 113 with a triangular cross section is formed. It is filled by the filling ring 114 on the outer wall of the anti-corrosion plate 107, so that the connection between the outlet 103 and the pipe is filled, preventing liquid from entering the sealing hole 111 from the gap between the outlet 103 and the pipe and corroding the sealing gasket 105, thus effectively protecting the sealing gasket 105.
[0036] In some embodiments, the two mounting rings 106 are arranged at opposite angles.
[0037] In actual use, the mounting ring 106 on the outlet 103 is inclined downwards, and the mounting ring 106 on the pipeline is inclined upwards. The two mounting rings 106 are arranged opposite each other. The purpose of this arrangement is to form an installation area between the two mounting rings 106, which facilitates the installation of the anti-corrosion plate 107.
[0038] In some embodiments, the sealing hole 111 is located on both sides of the bolt 110.
[0039] In actual use, the purpose of setting the two sealing holes 111 on both sides of the bolt 110 is to bring the two sealing holes 111 closer to the bolt 110, so that the sealing gasket 105 in the sealing hole 111 can be pressed more firmly after the bolt 110 and the threaded hole 109 are engaged.
[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 tank 117 through a pipeline, and the hot water inlet is connected to a high-temperature water tank 118 through a pipeline.
[0041] In actual use, the high-temperature water tank 118 is used to introduce high-temperature hot water into the hot water inlet, and the low-temperature water tank 117 is used to introduce low-temperature water into the cold water inlet 115.
[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, wastewater mother liquor tank 120, hot water tank 125, condensate tank, low temperature water pool 117 and high temperature water pool 118 are all set on the ground, the waste residue centrifuge 122 is set at a height of 5m above the ground, and the centrifuge high-level tank 121, feed high-level tank 123, wastewater evaporator 126 and condenser 101 are all set at a height of 10m above the ground.
[0044] The outlet of wastewater tank 119 is connected to the inlet of feed tank 123 via a pipeline. The outlet of feed tank 123 is connected to the wastewater inlet of wastewater evaporator 126. The outlet 103 of wastewater evaporator 126 is connected to the inlet of heater 124 via a pipeline. The outlet of heater 124 is connected to the inlet 102 of wastewater evaporator 126 via a pipeline. The pipeline between the inlet of heater 124 and the outlet of wastewater evaporator 126 is connected to the inlet of centrifugal feed tank 121 via a discharge pump. The inlet of feed tank 123 is connected to the outlet of centrifugal feed tank 121. The outlet end is also connected to the centrifugal high-level tank 121 via a pipeline. The outlet end of the centrifugal high-level tank 121 is connected to the inlet end of the waste residue centrifuge 122 via a pipeline. The waste residue centrifuge 122 is connected to the wastewater mother liquor tank 120 via a pipeline. The discharge end of the wastewater mother liquor tank 120 is connected to the inlet end of the feeding high-level tank 123 via a mother liquor recovery pump. The outlet end of the feeding high-level tank 123 is also connected to the inlet end of the wastewater mother liquor tank 120 via 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 wastewater in wastewater tank 119 is pumped into the high-level feed tank 123 via a wastewater transfer pump. The high-level feed tank 123 initially stores the wastewater, which is then fed into the wastewater evaporator 126. At this time, the vacuum pump is turned on to create a vacuum in the wastewater evaporator 126, causing vacuum-induced low-temperature evaporation inside the evaporator. This is why the wastewater evaporator 126 is set at a height of 10m, as the pipe between the inlet of the heater 124 and the outlet of the wastewater evaporator 126 needs to be long enough to support the vacuum-induced low-temperature evaporation in the wastewater evaporator 126. The wastewater circulates into the wastewater evaporator 126 after passing through the heater 124. During evaporation, the wastewater evaporator 126 generates steam and condensate, which are then piped into the condenser 101. The condenser 101 exchanges heat with the low-temperature water tank 117 and the high-temperature water tank 118, and discharges the condensate into the condensate tank for collection. During the wastewater evaporation process, the residual liquid is temporarily stored in the centrifugal high-level tank 121 by the discharge pump, and then undergoes solid-liquid separation in the waste residue centrifuge 122. The solid waste is classified and treated, and the liquid is fed into the wastewater mother liquor tank 120. In order to reduce the amount of solid residue in the wastewater mother liquor tank 120, the wastewater in the wastewater mother liquor tank 120 needs to be repeatedly centrifuged. Finally, the wastewater mother liquor tank 120 recovers the waste liquid, completing the overall evaporation of the wastewater.
