[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model embodiment discloses a desulfurization reactor for wastewater.

[0027] Example 1

[0028] The utility model provides Figure 1-3 A wastewater desulfurization reactor shown comprises a housing 1 and a partition 2 fixedly arranged on the upper end of the inner wall of the housing 1, the upper surface of the partition 2 is inclined, a floating plate 3 is contacted with the upper end of the inner wall of the housing 1, a counterweight 16 is fixedly arranged on the top of the floating plate 3, a plurality of feed pipes 4 are fixedly penetrated on the top of the housing 1, and the lower ends of the feed pipes 4 are fixedly penetrated inside the floating plate 3;

[0029] A pump body 5 is fixedly provided on the outer wall of the box body 1, and a water suction pipe 6 and a drainage pipe 7 are respectively connected at both ends of the pump body 5. The pipe mouth of the drainage pipe 7 extends into the lower part of the interior of the box body 1, and a connecting pipe 8 is fixedly penetrated through the upper end of the side wall of the box body 1. The pipe mouth of the connecting pipe 8 passes through the box body 1 and is connected with the water suction pipe 6. The feed pipe 4 and the connecting pipe 8 are both corrugated telescopic pipes. The lower end of the connecting pipe 8 is fixedly provided inside the floating plate 3, and a filter screen 18 is fixedly provided at the lower end of the inner wall of the connecting pipe 8. A feeding port is opened at the middle end of the outer wall of the box body 1, and a discharge pipe 9 is connected at the lower end of the side wall of the box body 1. A discharge valve 10 is fixedly sleeved on the pipe wall of the discharge pipe 9.

[0030] Before desulfurization treatment of the wastewater, the wastewater is fed to the partition 2 through the left feed pipe 4, and then the lime milk is fed to the partition 2 through the right feed pipe 4, so that the lime milk contacts the wastewater to react. At this time, the float plate 3 is limited and located at the upper end of the inner part of the box body 1. After the reaction is completed, the reactants are allowed to stand so that the neutralized water and the lime paste are arranged in layers. Then the lower float plate 3 contacts the water surface of the neutralized water. At this time, the pump body 5 is started, so that the pumping pipe 6 cooperates with the connecting pipe 8 to start to quickly suck the neutralized water. Under the pressure of the counterweight block 16, the float plate 3 is always in contact with the water surface of the neutralized water, so that when it contacts the surface of the lime paste, the neutralized water is completely sucked. At this time, due to the limitation of the filter screen 18, the lime paste cannot be sucked. At this time, the pump body 5 can be closed so that the neutralized water can be purified by the sediment in the lower space of the box body 1.

[0031] Example 2

[0032] Example 2 is based on Example 1 in order to limit the initial position of the floating plate 3 to ensure that the wastewater can react stably with the lime milk, such as Figure 1-2 As shown, a lifting and limiting mechanism is provided at the top of the floating plate 3, and the lifting and limiting mechanism includes a pull rope 11, one end of the pull rope 11 is fixedly connected to the top of the floating plate 3, and the other end of the pull rope 11 passes through the box body 1 and is fixedly provided with a sleeve 12, and a movable groove is opened at the upper end of the outer wall of the box body 1, and the sleeve 12 is slidably set in the movable groove, and a telescopic rod 13 is fixed between the inner wall of the movable groove, and a positioning rod 14 is slidably passed through the inner wall of the sleeve 12, and a positioning groove is opened on the inner wall of the movable groove to cooperate with the positioning rod 14 for insertion, and a spring 15 is provided on the rod wall of the positioning rod 14, and the two ends of the spring 15 are respectively fixedly connected to the positioning rod 14 and the sleeve 12.

[0033] Under the connection of the pull rope 11, the initial position of the float 3 can be determined by plugging the positioning rod 14 and the positioning groove. When the neutralizing water needs to be sucked, the positioning rod 14 is pulled to pull the positioning rod 14 out of the positioning groove. At this time, with the support of the telescopic rod 13 and the connection of the pull rope 11, the counterweight block 16 drives the float 3 to fall quickly through its own gravity and contact the water surface of the neutralizing water.

[0034] Example 3

[0035] Example 3 Based on Example 1, in order to enable the neutralization water and lime paste to be taken out from the inside of the box 1 after the reaction is completed, Figure 1 As shown, a discharge port is provided at the upper end of one side of the box body 1 close to the feeding port, a blocking block 17 is embedded inside the discharge port, and the outer wall of the blocking block 17 is screwed and fixed to the box body 1 by bolts.

[0036] During the reaction, the sealing cooperation between the block 17 and the discharge port can enable the reaction to proceed stably at the upper end of the interior of the housing 1. After all the neutralized water is sucked out, the block 17 is taken out from the discharge port. At this time, under the action of the inclined surface of the partition 2, the deposited lime paste can flow out of the discharge port and away from the housing 1 by its own gravity, so that the reactor can continue to treat the wastewater later.

[0037] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
