Description

Technical Field

[0001] This utility model relates to the field of hydrogen peroxide production technology, and in particular to an alumina entrainer for a bleaching bed used in hydrogen peroxide production. Background Technology

[0002] Currently, in the production process of hydrogen peroxide, traditional clay beds typically use stainless steel wire mesh as a filter layer at the bottom inlet distributor and the top outlet distributor. After the alumina is filled, it is necessary to cover it with wire mesh and then lay ceramic balls on top of the wire mesh to intercept alumina particles. However, this method has significant drawbacks in practical use:

[0003] 1. The wire mesh is easily damaged: Stainless steel wire mesh has low strength. During the filling process of alumina and ceramic balls (impact during pouring) or during long-term operation (flushing of working fluid, thermal stress caused by temperature fluctuations), it is prone to tearing and local damage, which causes alumina particles to leak out from the damaged area.

[0004] 2. High consumption of auxiliary materials: In order to enhance the interception effect, the existing process requires an additional layer of wire mesh to be covered on top of the alumina after the alumina is filled, and ceramic balls are laid on top of the wire mesh. The amount of ceramic balls used is large (about 1-1.5 tons per unit of white clay bed), which increases the material cost.

[0005] 3. High risk of confined space operation: Laying ceramic balls and top wire mesh requires operators to enter the clay bed tank (confined space) to work. The operation time is long (about 0.5-1 hour), and there are safety risks such as lack of oxygen and suffocation. In addition, the flatness of manual laying is difficult to guarantee, which can easily form local gaps and cause particles to be trapped.

[0006] Therefore, an improved structure is needed that can enhance interception reliability, reduce consumable consumption, and lower operational risks. Utility Model Content

[0007] The purpose of this invention is to provide an alumina entrainer for a clay bed used in hydrogen peroxide production, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an alumina entrainment in a clay bed for hydrogen peroxide production, comprising a clay bed body, an alumina particle placement groove formed within the clay bed body, an inlet pipe fixedly installed within the clay bed body, an inlet port fixedly installed at one end of the inlet pipe, a first Johnson mesh mechanism provided on the inlet pipe, and an outlet pipe fixedly installed within the clay bed body.

[0009] Preferably, a cover is fixedly installed inside the clay bed body, and a fixing mesh plate is fixedly installed inside the clay bed body.

[0010] Preferably, one end of the liquid outlet pipe is fixedly installed with a liquid outlet, and a second Johnson mesh mechanism is provided inside the liquid outlet pipe.

[0011] Preferably, the first Johnson mesh mechanism includes a connecting block disposed on the inlet pipe, one end of the connecting block being welded with a welding ring, and the inlet pipe and the welding ring being connected by a bottom sealing weld.

[0012] Preferably, a vertical reinforcing rib is fixedly installed inside the connecting block, and a circumferential filter wire is fixedly installed on the vertical reinforcing rib.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, the connecting block can be firmly fixed to the inlet pipe by the setting of the welding ring and the bottom sealing structure, so as to ensure that it can maintain stable filtration performance when subjected to the impact of alumina and ceramic ball filling, as well as the long-term working fluid flushing and temperature fluctuation.

[0015] In this invention, the rigidity of the structure is increased by setting vertical reinforcing ribs and circumferential filter wires, which overcomes the problem of easy breakage of traditional wire mesh and avoids clogging or contamination of downstream equipment.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] like Figure 1-3 As shown, this embodiment provides an anti-alumina entrainment alumina bed for hydrogen peroxide production, including an alumina bed body 1, an alumina particle placement groove 4 inside the alumina bed body 1, an inlet pipe 5 fixedly installed inside the alumina bed body 1, an inlet port 6 fixedly installed at one end of the inlet pipe 5, a first Johnson mesh mechanism 7 provided on the inlet pipe 5, an outlet pipe 8 fixedly installed inside the alumina bed body 1, a cap 2 fixedly installed inside the alumina bed body 1, a fixed mesh plate 3 fixedly installed inside the alumina bed body 1, an outlet port 9 fixedly installed at one end of the outlet pipe 8, and a second Johnson mesh mechanism 10 provided inside the outlet pipe 8;

[0023] First, alumina particles are placed in the alumina particle placement tank 4. The working liquid flows from the inlet pipe 5 into the first Johnson mesh mechanism 7, and then through the fixed mesh plate 3 into the alumina particle placement tank 4, where it reacts with the alumina particles in the alumina particle placement tank 4. The reacted working liquid flows from bottom to top in the alumina particle placement tank 4. After reaching a certain height, it flows through the second Johnson mesh mechanism 10 into the outlet pipe 8, and then enters the downstream process through the outlet 9.

[0024] In this embodiment of the present invention, specifically, the first Johnson mesh mechanism 7 includes a connecting block 71 disposed on the liquid inlet pipe 5, one end of the connecting block 71 is welded with a welding ring 72, and the liquid inlet pipe 5 and the welding ring 72 are welded together by a sealing bottom 73.

[0025] To make the connection block 71 more secure, a welding ring 72 is placed between the connection block 71 and the inlet pipe 5. The connection block 71 and the inlet pipe 5 are connected together by welding. Then, by sealing the bottom 73, the complete fusion of the weld root can be ensured, improving the welding quality. In this way, the connection block 71 can be firmly fixed to the inlet pipe 5.

[0026] In this embodiment of the utility model, specifically, a vertical reinforcing rib 74 is fixedly installed inside the connecting block 71, and a circumferential filter wire 75 is fixedly installed on the vertical reinforcing rib 74;

[0027] The vertical reinforcing ribs 74 and the circumferential filter wires 75 increase its rigidity, overcoming the problem of easy breakage of traditional wire mesh and preventing clogging or contamination of downstream equipment.

[0028] Working principle: First, the welding ring 72 is placed between the connecting block 71 and the inlet pipe 5. The connecting block 71 and the inlet pipe 5 are then connected together by welding. Then, the bottom sealing 73 ensures complete fusion at the root of the weld, improving welding quality. This firmly fixes the connecting block 71 to the inlet pipe 5, ensuring stable filtration performance even under the impact of alumina and ceramic ball loading, long-term working fluid scouring, and temperature fluctuations, preventing tearing or localized damage. The vertical reinforcing ribs 74 and circumferential filter wires 75 increase its rigidity, overcoming the problem of easy breakage of traditional wire mesh. To avoid clogging or contamination of downstream equipment, alumina particles are first placed in the alumina particle placement tank 4. Then, the working fluid inlet pipe is connected to the inlet 6. The working fluid flows from the inlet pipe 5 to the first Johnson mesh mechanism 7, where it undergoes the first step of filtration. After passing through the fixed mesh plate 3, it flows into the alumina particle placement tank 4 and reacts with the alumina particles in the tank. The reacted working fluid flows upward in the alumina particle placement tank 4. After reaching a certain height, it flows through the second Johnson mesh mechanism 10 into the outlet pipe 8, and then enters the downstream process through the outlet 9.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
