Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage filler high-efficiency fluidization device. Background Art

[0002] In recent years, with the vigorous development of industry and agriculture, more and more organic compounds have been widely used in human production and life, accompanied by a large number of toxic and harmful compounds entering the water environment through various channels. In particular, the development of modern chemical industries such as petrochemicals, oil refining, pharmaceuticals, and organic synthesis has produced a large amount of wastewater containing organic compounds that is directly discharged into rivers without effective treatment, causing increasingly serious pollution of limited water resources and seriously threatening human health. Undoubtedly, the treatment of refractory wastewater has become a difficult and hot spot in the field of water treatment in recent decades. In order to ensure the water environment required for human survival, it is imperative to develop new technologies for economical and efficient refractory water treatment.

[0003] The application prospects of advanced catalytic oxidation technology in the treatment of difficult-to-degrade wastewater have been widely recognized by the industry, but the grid basket method of fixing the catalyst filler is usually adopted. The disadvantages of this method are: the catalyst filler has poor fluidity and is easy to compact, which affects the mass transfer efficiency. This will not only increase the use of catalyst filler and increase operating costs, but also affect the efficiency and effect of wastewater treatment. Summary of the invention

[0004] In order to overcome the deficiencies in the prior art, the purpose of the present invention is to provide a high-efficiency fluidization device for sewage fillers, which, on the one hand, can effectively fluidize the fillers and improve the solid-liquid mass transfer effect; on the other hand, can prevent the filler from being blocked or compacted during sewage treatment.

[0005] The present invention solves the above problems by the following technical means:

[0006] A sewage filler high-efficiency fluidization device comprises a sewage treatment cylinder and a water inlet cylinder arranged at the center of the sewage treatment cylinder, the sewage treatment cylinder is divided into an outer water outlet cylinder and an inner reaction cylinder by a partition, the top of the water inlet cylinder is connected with the reaction cylinder, and the bottom of the partition is provided with a water passage connecting the reaction cylinder and the water outlet cylinder; the bottom plate of the sewage treatment cylinder is composed of a left plate and a right plate respectively arranged on the left and right sides of the water inlet cylinder, the left plate and the right plate both comprise a fixed plate body and a swing plate body, the fixed plate body is fixedly connected to the side wall of the sewage treatment cylinder, one side of the swing plate body is hinged to the fixed plate body for swinging up and down, and a paddle is hinged on the upper side of the free end of the swing plate body; the left and right side walls of the water inlet cylinder are both provided with notches, and a baffle for opening and closing the notch is installed at the notch, the bottom of the baffle is hinged to the side wall of the water inlet cylinder for swinging left and right, the top of the baffle is assembled with the corresponding swing plate body for sliding left and right, and the baffle is supported by an inclined spring; a filler support mesh plate is assembled for sliding up and down in the water inlet cylinder.

[0007] Furthermore, a first slide rail is provided at the bottom of the swing plate body and is slidably assembled with the corresponding baffle plate left and right.

[0008] Furthermore, the inner wall of the water inlet cylinder is provided with a second slide rail which is slidably assembled with the filler support mesh plate up and down.

[0009] Furthermore, a spring support plate is connected to the fixed plate body, and one end of the spring away from the baffle is connected to the spring support plate.

[0010] Furthermore, a water inlet pipe and / or an air inlet pipe is connected to the bottom of the water inlet cylinder.

[0011] Furthermore, a water outlet pipe is provided on the side wall of the water outlet cylinder near the top.

[0012] Furthermore, a top contact sensor and a bottom contact sensor are respectively provided on the top and the bottom of the water inlet cylinder.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The sewage packing high-efficiency fluidization device of the present application, when working, the packing support mesh plate moves upward under the action of water pressure, and simultaneously pushes the packing to move upward. When it moves to the paddle position, the paddle can flip upward and will not hinder the upward movement of the packing support mesh plate; the packing enters the reaction tube at the upper end, and when the packing support plate moves to contact the top contact reactor, the water inflow stops, and the packing support mesh plate sinks under the action of gravity. When it drops to the paddle position, it pushes the paddle to flip downward. When the paddle flips to a horizontal state, due to the obstruction of the protruding end of the swing plate body, the paddle cannot swing relative to the reactor. The movable plate body continues to flip downward, at this time, it will push the swing plate body to flip downward, and simultaneously push the baffle plate to swing outward, opening the gap in the side wall of the water inlet cylinder, so that the filler returns to the water inlet cylinder through the gap again. When the supporting mesh plate is out of contact with the paddle, the spring pushes the baffle plate and the swing plate body to reset. After the filler supporting mesh plate sinks to the bottom contact sensor, the water inlet is started. In this way, the filler is circulated and fluidized in the equipment. On the one hand, the filler is effectively fluidized and the solid-liquid mass transfer effect is improved; on the other hand, it can prevent filler blockage, compaction and other problems that occur during sewage treatment.

[0015] (2) The sewage filler high-efficiency fluidization device of the present application can select the process according to the type of sewage through the reserved water and air inlet pipes. When the MBBR method is used to treat domestic sewage, internal circulation fluidization of the filler can be realized to achieve mud film symbiosis; when treating difficult-to-degrade organic wastewater, the interior is filled with catalysts and water and air are introduced from the bottom to prevent the catalyst from caking and increase the mass transfer effect of solid, liquid and gas.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of description and simplified description of the present invention, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0021] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0022] like Figure 1 to Figure 2 As shown, this embodiment provides a sewage filler high-efficiency fluidization device, including a sewage treatment cylinder and a water inlet cylinder 1 arranged in the center of the sewage treatment cylinder, the sewage treatment cylinder is divided into an outer water outlet cylinder 3 and an inner reaction cylinder 2 by a partition, the top of the water inlet cylinder is connected to the reaction cylinder, and the bottom of the partition is provided with a water passage connecting the reaction cylinder and the water outlet cylinder, and the gap of the water passage allows water to pass through, but does not allow filler to pass through.

[0023] The bottom plate of the sewage treatment cylinder is composed of a left plate and a right plate respectively arranged on the left and right sides of the water inlet cylinder, and the left plate and the right plate both include a fixed plate body 15 and a swinging plate body 7. The fixed plate body is fixedly connected to the side wall of the sewage treatment cylinder, and one side of the swinging plate body is hinged to the fixed plate body for swinging up and down. A paddle 8 is hinged on the upper side of the free end of the swinging plate body, and the hinge point between the paddle and the swinging plate body is a certain distance away from the free end of the swinging plate body. In this way, when the paddle is flipped downward by the pushing member to be flush with the swinging plate body, it will not be able to continue to flip downward relative to the swinging plate body due to the blocking effect of the swinging plate body. If the pushing member continues to push downward, it will drive the paddle and the swinging plate body to flip downward synchronously relative to the fixed plate body.

[0024] The left and right side walls of the water inlet cylinder are both provided with gaps, and baffles 6 are installed at the gaps to realize the opening and closing of the gaps. The bottom of the baffle is hinged to the side wall of the water inlet cylinder for left and right swinging, and the top of the baffle is slidably assembled with the corresponding swing plate body for left and right sliding. The baffle is supported by an inclined spring 9; a filler support mesh plate 5 is slidably assembled up and down in the water inlet cylinder.

[0025] The bottom of the water inlet cylinder is connected with a water inlet pipe 4 and / or an air inlet pipe 14; a water outlet pipe 13 is arranged on the side wall of the water outlet cylinder near the top; a top contact sensor 12 and a bottom contact sensor 11 are arranged at the top and bottom of the water inlet cylinder respectively.

[0026] In this embodiment, a first slide rail is provided at the bottom of the swing plate body and is slidably assembled with the corresponding baffle plate left and right; and a second slide rail is provided on the inner wall of the water inlet cylinder and is slidably assembled with the filler support mesh plate up and down.

[0027] In this embodiment, a spring support plate 16 is connected to the fixed plate body, and one end of the spring away from the baffle is connected to the spring support plate.

[0028] During operation, a filler 10 is placed in the water inlet cylinder, sewage, ozone or oxygen enters the water inlet cylinder from the reserved water inlet pipe 4 or air inlet pipe, and the filler support mesh plate 5 moves upward under the action of water pressure. The catalyst or filler 10 is pushed upward by the filler support mesh plate. When passing the position of the swing plate body, the paddle can be freely flipped upward without hindering the filler support mesh plate 8 from moving upward. The sewage and the catalyst or filler 10 enter the reaction cylinder 2 from the upper end of the water inlet cylinder 1. After the sewage is treated in the reaction cylinder 2, it enters the water outlet cylinder 3 from the bottom water channel and is discharged through the upper water outlet pipe 13; when the filler support mesh plate 8 moves to contact with the top contact sensor 12, the water inflow stops and the filler stops. The material support mesh plate 8 sinks under the action of gravity. When it falls to the position of the swing plate body 7, it pushes the paddle and the swing plate body to turn over synchronously along the route a. The baffle moves along the route b under the pressure of the swing plate body 7, so that the bottom of the water inlet cylinder 1 and the bottom of the reaction cylinder 2 are connected through the gap, and the filler 10 returns to the water inlet cylinder 1 again. When the support mesh plate is out of contact with the paddle, the spring pushes the baffle and the swing plate body to reset. After the filler support mesh plate sinks to the bottom contact sensor, water inlet is started. In this way, the filler is circulated and fluidized in the equipment. On the one hand, the filler is effectively fluidized and the solid-liquid mass transfer effect is improved; on the other hand, it can prevent the filler from being blocked and compacted during sewage treatment.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
