Detailed Description

The utility model will be described in detail below with reference to the drawings and detailed description thereof.

Referring to fig. 1-2, an automatic activated carbon regeneration corrugated labyrinth chamber comprises a labyrinth chamber 10, wherein an inner wave plate 20 and an outer wave plate 30 are fixed in the labyrinth chamber 10, so that a space surrounded by the inner wave plate 20, the outer wave plate 30 and two side walls 11 of the labyrinth chamber 10 is a regeneration channel 39, the regeneration channel 39 is S-shaped, and the inner wave plate 20 and the outer wave plate 30 are folded along the axial direction of the regeneration channel 39.

The labyrinth chamber 10 is simply constructed to facilitate the fixation of the inner wave plate 20 and one outer wave plate 30, and has no influence on the regeneration passage 39 itself and the realization of activated carbon regeneration.

As shown in fig. 1 to 3, the external wave plate 30 includes a plurality of V-shaped external wave plate units 32 fixed in series, and an angle between two plates of the external wave plate units 32 (see reference numeral 321) is 110 °.

Referring to fig. 1-3 (because the inner wave plate 20 is similar in structure to the outer wave plate 30, the inner wave plate 20 is not separately drawn), the inner wave plate 20 includes a plurality of V-shaped inner wave plate units 22 fixed in series, and an angle between two plates of the inner wave plate units 22 is 110 °.

In order to facilitate the water flow, the number of the inner wave plate units 22 and the outer wave plate units 32 is N, N is a natural number greater than 6, N is a natural number less than or equal to N, and the lowest part (see reference numeral 31) of the nth outer wave plate unit 32 and the left side edge of the nth inner wave plate unit 22 (see reference numeral 21) are located in the same vertical plane, wherein the vertical plane is a plane perpendicular to the axial direction of the regeneration passage 39, and the distance d between the inner wave plate unit 22 and the outer wave plate unit 32 is equal in any vertical plane.

In order to improve efficiency, as shown in fig. 1-4, an activated carbon regeneration device comprises four automatic activated carbon regeneration corrugated labyrinth chambers 100 as described above, as shown in fig. 2, wherein the labyrinth chamber 10 is in a fan shape, the included angle between two side walls 11 (see reference numeral 111) is 90 °, and the four automatic activated carbon regeneration corrugated labyrinth chambers 100 are distributed on the same columnar space. Thus, a column or a pipe is designed, which can fix four automatic regeneration corrugated labyrinth chambers 100 for activated carbon, thereby improving the regeneration efficiency.

The working principle is as follows:

in use, the regeneration passage 39 has an axis oriented downward.

Generally, activated carbon put into purification is entangled by solid suspended matters (SS) in sewage, and after purification, the activated carbon is deposited on the bottom of a tank, and the suspended matters are more in the bottom of the tank.

When the system is backwashed, the air lift pump lifts the activated carbon at the bottom of the tank along with the suspended matter (i.e., the "dirty water") to the upper port of the pump tube and radiates the peripheral radiation out (i.e., into the left port of the regeneration channel 39 in fig. 1), and then falls under gravity into four sets of corrugated labyrinth chambers uniformly distributed along the circumference of the pump tube, flowing in the direction of the arrow in fig. 1.

Under the action of the inner corrugated plate and the outer corrugated plate, dirty water and active carbon collide with the inner corrugated plate and the outer corrugated plate at a plurality of positions, during the collision, the active carbon is separated from suspended matters, the dirty water finally flows out from the lower opening of the corrugated labyrinth chamber (namely the right port entering the regeneration channel 39 in fig. 1), the suspended matters are separated from the active carbon in the collision process and float to the vicinity of the liquid level, and finally are discharged through a drain pipe, so that the active carbon is regenerated and can be reused.

See the prior art for further content.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several changes and modifications can be made without departing from the general inventive concept, and these should also be regarded as the scope of the utility model.
