Description

Technical Field

[0001] This utility model relates to the field of high salinity desalination technology, and in particular to a wastewater treatment device for high salinity desalination equipment. Background Technology

[0002] High-salinity wastewater refers to wastewater containing organic matter and at least 3.5% total dissolved solids by mass, including high-salinity domestic wastewater and high-salinity industrial wastewater. It mainly originates from industrial production and domestic water use that directly utilizes seawater, food processing plants, chemical plants, and the extraction and processing of oil and natural gas. In addition to organic pollutants, this wastewater also contains large amounts of inorganic salts, such as Cl-, SO42-, Na+, and Ca2+ ions. If this high-salinity, high-organic-matter wastewater is discharged directly without treatment, it will inevitably cause great harm to aquatic organisms, drinking water, and industrial and agricultural water use. Desalination equipment can be used to treat it, but this process will produce wastewater.

[0003] There are many methods for treating wastewater. Discharging into surface water systems and the ocean are both methods that should only be used in moderation; excessive discharge will harm nature, so these methods are generally not recommended. Evaporation ponds can be used to treat wastewater, but existing evaporation ponds do not have the function of preventing wastewater from overflowing. When wastewater overflows, it will pollute water bodies or the environment.

[0004] Therefore, it is necessary to provide a wastewater treatment device for high-salinity desalination equipment to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a wastewater treatment device for high salinity desalination equipment.

[0006] This utility model provides a wastewater treatment device for high-salinity desalination equipment, comprising: an evaporation tank located on the ground, a U-shaped movable trough at the top of the evaporation tank, a protective frame slidably connected to the inner surface of the movable trough, the side of the protective frame being connected to the top of the movable frame which can float in water via an inverted L-shaped connecting plate, the movable frame being disposed inside the evaporation tank, a U-shaped protective trough on the ground outside the evaporation tank, a plurality of water outlet holes at the bottom of the protective trough, one end of an L-shaped water outlet pipe being connected to a recovery port via a solenoid valve, the recovery port being disposed on the inner side of the evaporation tank.

[0007] Preferably, a second protective frame is installed at one end of the top of the protective groove, and the second protective frame is in the shape of an "U".

[0008] Preferably, all sides of the movable frame are provided with guide blocks, the guide blocks are slidably connected to guide grooves, and the guide grooves are disposed on the inner surface of the evaporation tank.

[0009] Preferably, the top of the protective frame is connected to an upper baffle, and the upper baffle is in the shape of an "U".

[0010] Preferably, the bottom of the movable tank is provided with a plurality of second water outlet holes, the second water outlet holes are connected to one end of an L-shaped second water outlet pipe, and the other end of the second water outlet pipe is connected to a second recovery port through a second solenoid valve. The second recovery port is located on the inner side of the evaporation tank.

[0011] Preferably, there are multiple connecting plates, which are linearly and equidistantly distributed on the top of the moving frame.

[0012] Preferably, an alarm plate is connected to the top of the inner surface of the evaporation tank, and a push-button alarm is installed at the bottom of the alarm plate.

[0013] Compared with related technologies, the wastewater treatment device for high-salinity desalination equipment provided by this utility model has the following beneficial effects:

[0014] 1. This utility model, by setting up a movable frame, allows wastewater to be introduced into the evaporation tank. As the wastewater gradually increases, the buoyancy of the wastewater will cause the movable frame to move upward, and the connecting plate will simultaneously move the protective frame upward, thus protecting the top of the evaporation tank and preventing wastewater from overflowing when the evaporation tank is full. By setting up a protective trough, a second line of defense can be set up on the outside of the evaporation tank. When the protective frame can no longer block the wastewater, the wastewater can be collected through the protective trough. After the wastewater in the evaporation tank is treated, the wastewater collected in the protective trough can be sent back to the evaporation tank through the recovery port by opening the solenoid valve for further treatment. By setting up the protective trough, the ability to prevent wastewater overflow is effectively improved.

[0015] 2. By setting an upper baffle, this utility model can protect the top of the evaporation tank and improve the protective frame's ability to prevent sewage overflow.

[0016] 3. This utility model features an alarm plate with a push-button alarm. When the moving frame moves to the top of the evaporation tank, it squeezes the push-button alarm, thereby activating it to immediately alert the operator to handle the sewage overflow. Attached Figure Description

[0023] It should be noted that by setting the movable frame 3, after sewage is introduced into the evaporation tank 2, as the sewage gradually increases, the buoyancy of the sewage will drive the movable frame 3 to move upward, and at the same time, the protective frame 6 will move upward through the connecting plate 4, thereby protecting the top of the evaporation tank 2 and preventing sewage from overflowing when the evaporation tank 2 is filled with sewage. By setting the protective trough 8, a second line of defense can be set on the outside of the evaporation tank 2. When the protective frame 6 can no longer block the sewage, the sewage can be collected through the protective trough 8. After the sewage in the evaporation tank 2 has been treated, the sewage collected in the protective trough 8 can be sent back to the evaporation tank 2 through the recovery port 15 by opening the solenoid valve 16 to wait for treatment. By setting the protective trough 8, the ability to prevent sewage overflow is effectively improved.

[0024] In the embodiments of this utility model, reference is made to Figure 1As shown, one end of the top of the protective groove 8 is provided with a second protective frame 9, and the second protective frame 9 is in the shape of a "square".

[0028] In an embodiment of the present invention, refer to Figure 1 As shown, the top of the protective frame 6 is connected with an upper baffle 7, and the upper baffle 7 is in the shape of a "square".

[0029] It should be noted that: by providing the upper baffle 7, the upper part of the evaporation tank 2 can be protected, and the protective ability of the protective frame 6 against sewage overflow can be improved;

[0034] In an embodiment of the present invention, refer to Figure 1As shown, an alarm plate 5 is connected to the top of the inner surface of the evaporation tank 2, and a push-button alarm is installed at the bottom of the alarm plate 5.

[0035] It should be noted that by setting up an alarm plate 5 with a press-type alarm, when the moving frame 3 moves to the top of the evaporation tank 2, it will squeeze the press-type alarm, thereby activating the press-type alarm to remind the operator to deal with the sewage overflow as soon as possible.

[0036] The working principle of the wastewater treatment device for high-salinity desalination equipment provided by this utility model is as follows:

[0037] By setting up the movable frame 3, after sewage is introduced into the evaporation tank 2, as the sewage gradually increases, the buoyancy of the sewage will drive the movable frame 3 to move upward, and at the same time, the protective frame 6 will move upward through the connecting plate 4, thereby protecting the top of the evaporation tank 2 and preventing sewage from overflowing when the evaporation tank 2 is filled.

When the protective frame 6 can no longer block the sewage, the sewage can be collected through the protective trough 8. After the sewage in the evaporation tank 2 has been treated, the sewage collected in the protective trough 8 can be sent back to the evaporation tank 2 through the recovery port 15 by opening the solenoid valve 16 to wait for treatment. By setting up the protective trough 8, the ability to prevent sewage overflow is effectively improved.
