Technical Field

[0001] The utility model relates to a water outlet structure, in particular to a water outlet structure of a Fenton oxidation tower. Background Art

[0002] The Fenton oxidation reaction is a reaction in which the Fenton reagent composed of ferrous ions and hydrogen peroxide reacts to generate highly oxidizing hydroxyl radicals. The commonly used Fenton oxidation equipment is the Fenton oxidation tower, which is a vertical tower. The Fenton reagent is mixed in the tower by distributing water upwards to react, and finally the water is discharged through the water outlet tank at the top. The Fenton oxidation tower equipment has low capital investment cost, simple operation, and small footprint, and has been widely used in recent years.

[0003] At present, the water outlet of the Fenton tower generally includes a water outlet trough and a water outlet. Chinese utility model patent ZL201620887636.7 discloses a wastewater Fenton oxidation tower, in which an overflow trough with a water outlet function is installed on the left side of the upper end of the shell, and a water outlet is installed on the shell outside the overflow trough. Chinese utility model patent ZL 202022011059.4 discloses a combined denitrification and defoaming garbage leachate Fenton treatment device, including a tank body, a dosing port, a water outlet trough, a water outlet, etc. The water outlet trough is arranged on the inner wall of the tank body, and a triangular weir is arranged on the water outlet trough. The water outlet trough surrounds the inner wall of the tank body, and one side of the water outlet trough is connected to the water outlet. In the prior art, a single, open trough body is set as the water outlet structure in the Fenton tower. This design cannot control the speed of water outlet; in addition, the water outlet is opened on one side of the water outlet trough, and there is a problem of unsmooth water outlet.

[0026] Embodiment A water outlet structure of a Fenton oxidation tower

[0027] In this embodiment, Figures 1 to 4As shown, a water outlet structure of a Fenton oxidation tower mainly includes a water outlet trough 2 and an overflow trough 3. The water outlet trough 2 is provided on one side of the top inner wall of the Fenton tower body 1, and the overflow trough 3 is provided on the other side. The water outlet trough 2 includes a trough bottom arranged in the horizontal direction, a trough body which forms a circle with the inner wall of the tower body in the vertical direction, and a movable cover plate 21 covering the entire water outlet trough 2. The trough bottom, the trough body, the movable cover plate and the Fenton tower body wall together form a relatively closed accommodation space. A water inlet hole is opened on one side of the water outlet trough 2 located at the top of the inner wall of the Fenton oxidation tower tower body, that is, on the trough body, so that water can flow into the water outlet trough 2. In this embodiment, the water inlet hole is preferably a square hole 22. Of course, the water inlet hole can also be circular or other shapes. In this embodiment, it is preferably opened in the center of the trough body of the water outlet trough 2. Of course, it can also be set at other positions in the middle of the trough body. The size of the square hole 22 can be set according to the requirements of the Fenton oxidation reaction in the tower.

[0028] Two lower baffles 23a / b are arranged perpendicular to the bottom of the water outlet tank 2. The two lower baffles 23a / b are symmetrically arranged on both sides of the square hole 22. The two lower baffles 23a / b respectively form two water outlet spaces with the tank bodies on both sides. The upper side of the lower baffles 23a / b is flush with the lower side of the square hole 22. The lower baffles 23a / b can prevent crystals or other solid impurities from entering the water outlet spaces on both sides and causing sedimentation blockage.

[0029] Two vertical upper movable baffles 24a / b are detachably provided above the lower baffle 23a / b, and a diversion water outlet 25a / b is left between the lower side of the upper movable baffle 24a / b and the upper side of the lower baffle 23a / b. By changing the height of the upper movable baffle 24a / b, the size of the diversion water outlet 25a / b can be adjusted to control the water outlet speed.

[0030] Water outlets 26a / b are respectively provided at the bottom of the groove of the two water outlet spaces, and water outlet pipes 27a / b vertically arranged downward are respectively connected below the two water outlets 26a / b. The lower ends of the water outlet pipes 27a / b are bent toward the side wall of the tower body 1 and connected to the external water outlets 28a / b arranged on the side wall of the tower body 1. The water outlet pipes 27a / b of the utility model are relatively long in vertical direction, and the external water outlets 28a / b are arranged at the lower part of the reaction zone in the tower, so that the water flow forms a large height difference between the water outlets 26a / b and the external water outlets 28a / b. The large height difference forms a higher water pressure, so that the water outlet structure can smoothly discharge water without adding a water pump device.

[0031] The water outlet trough 2 is covered with a movable cover 21. On the one hand, the movable cover 21 can close the upper part of the water outlet trough 2 so that water can only enter the water outlet trough 2 through the square hole 22. The water then passes through the lower baffle 23a / b into the water outlet space. Solid impurities such as crystals are blocked by the lower baffle 23a / b, greatly reducing the problem of water outlet blockage. On the other hand, the movable cover 21 can be opened at any time to facilitate operators to observe and clean the water outlet trough 2.

[0032] The overflow trough 3 opens upward, and the overflow trough body and the overflow trough bottom form an overflow space with the inner wall of the tower body 1. An overflow port 31 is provided on the side wall of the tower body 1 on the side of the overflow trough 3. The opening level of the overflow trough 31 is higher than the upper side of the square hole 22 of the outlet trough 2. When the water level in the tower body 1 exceeds the square hole 22 of the outlet trough 2 and continues to rise to the opening level of the overflow trough 3, the water will flow out from the overflow port 31 of the overflow trough 3. When water flows out of the overflow port 31, it may be caused by the water outlet trough 2 being too small, the water level in the tower being too high, or the outlet trough 2 being blocked, which is convenient for operators to adjust production in time.

[0033] When using this embodiment, the water after the post-treatment of the Fenton oxidation reaction in the tower enters the water outlet space on both sides through the water inlet hole of the water outlet tank 2, then enters the outlet pipe 27a / b from the outlet 26a / b and flows downward, and finally flows out from the external outlet 28a / b. The lower baffle 23a / b in the water outlet tank 2 blocks some impurities such as crystals that may be contained, thereby reducing the possibility of precipitation blockage caused by the water outlet space on both sides. The size of the water inlet hole and the diversion water port 25a / b can be set or adjusted according to actual production needs. When water flows out of the overflow port 31, it may be caused by the diversion water port 25a / b of the water outlet tank 2 being too small, the water level in the tower being too high, or the blockage in the water outlet tank 2. At this time, the movable baffle 21 is opened for observation, judgment and treatment.
