Description

Technical Field

[0001] The utility model relates to a white clay bed in the anthraquinone process for producing hydrogen peroxide. Background Art

[0002] The main defect of the conventional structure used in large quantities in the early stage of hydrogen peroxide development is that workers have to enter the confined space many times to work during filling or unloading. The packing plate, stainless steel wire mesh, inert porcelain balls, etc. are all heavy materials and components, which makes the workers' labor intensity very high and takes a long time to operate. The inert porcelain balls at the bottom of the lower head only play a supporting role, but if they are not replaced for a long time, the activated alumina balls (white clay) will be pulverized and agglomerated, which will increase the difficulty of disassembly and block the distribution holes of the liquid inlet distributor. The outlet cover at the drain port position of the lower head is generally made of a structure with a stainless steel plate cutting the drainage hole and covering it with a stainless steel wire mesh. It will also be blocked by the powdering and agglomeration of the white clay, resulting in poor drainage, and the working efficiency of the white clay bed will be greatly reduced.

[0003] The main defect of another kind of clay bed structure is that the supporting inert porcelain ball at the bottom of the lower head is eliminated on the basis of the conventional structure, and the structure of the grid and supporting parts (including I-beam, supporting ring, supporting grid) is used instead. The structure above it remains unchanged, but the construction process of loading and unloading is the same, and workers also need to enter the confined space for many times to work, which is labor-intensive. In this structure, the working fluid at the bottom of the lower head hardly flows upward and does not participate in the circulation, resulting in a waste of working fluid utilization, while increasing production costs and not fully utilizing the tower space.

[0004] The liquid distributors and outlet converging devices of the above two structures are both pipe-type with holes opened on stainless steel pipes. The hole diameters range from Φ10 to Φ30. Although the distribution pipes are covered with high-mesh stainless steel wire mesh, they are broken due to long-term extrusion and excessively fine wire diameters. In the production process, inert porcelain balls and white clay have the risk of falling into the pipes and blocking the pipes. Due to the limitations of its production method, the number of holes and pipes of the stainless steel pipe pipe-type distributor cannot evenly distribute the working fluid. If there are too many pipes, the production cost will be greatly increased. Utility Model Content

DETAILED DESCRIPTION

[0023] like Figures 1 to 8 The clay bed in the anthraquinone method hydrogen peroxide production process is characterized in that: the upper and lower ends of the cylinder 1 are sealed and fixed by an upper elliptical head 11 and a lower elliptical head 2 respectively, a liquid distributor feed pipe 7 is penetrated on one side wall of the cylinder 1, and a manhole 13 is provided on the other side wall of the cylinder 1 for personnel to enter and exit for work.

[0024] The upper elliptical head 11 is provided with an activated alumina ball filling port 8 for pouring the activated alumina balls 12 into the cylinder 1. The upper elliptical head 11 is also provided with a liquid outlet 10, and a liquid outlet collector 9 is provided at the bottom of the liquid outlet 10. The liquid outlet collector 9 is used to collect the working fluid and let it flow out through the liquid outlet 10.

[0025] A drain collector 5 and a liquid distributor 6 are respectively arranged in the lower elliptical head 2, and the drain collector 5 is connected with the drain port 3, and the drain port 3 is used to drain the working fluid in the cylinder 1 before unloading. The liquid distributor 6 includes an upper distributor 16 and a lower distributor 17, and the upper distributor 16 and the lower distributor 17 are relatively staggered. The liquid distributor 6 is connected with the liquid distributor feed pipe 7, and the liquid distributor feed pipe 7 includes a main pipe 14 and a steering connecting pipe 15. The main pipe 14 is penetrated through one side wall of the cylinder 1, and the main pipe 14 is connected with the steering connecting pipe 15, and the steering connecting pipe 15 is connected with the liquid distributor 6. The working fluid flows through the main pipe 14 and the steering connecting pipe 15, and flows into the activated alumina balls 12 through the liquid distributor 6. An activated alumina ball automatic unloader 4 is arranged at the bottom of the lower elliptical head 2 for unloading the activated alumina balls 12 in the cylinder 1.

[0026] The drain collector 5, the liquid distributor 6 and the liquid outlet collector 9 are respectively composed of a stainless steel trapezoidal wire mesh filter tube 18, the trapezoidal wire mesh has a small spiral pitch, a large distribution surface, and is distributed in all directions, which can not only improve the distribution efficiency, but also ensure that the activated alumina balls will not enter the pipeline, avoiding the risk of damage to valves, water pumps, instruments, etc. in the pipeline network, and is safe and reliable.

[0027] In the embodiment, the drain port 3, the automatic unloader of activated alumina balls 4 and the manhole 13 are closed, the activated alumina ball loading port 8 is opened, and the activated alumina balls 12 are poured into the cylinder 1 through the activated alumina ball loading port 8 by lifting.

[0028] After the working fluid flows through the main pipe 14 and the turning connecting pipe 15, it flows into the activated alumina ball 12 through the upper distribution pipe 16 and the lower distribution pipe 17. After the activated alumina ball 12 completes the adsorption process, the working fluid flows upward into the liquid outlet collector 9 and flows out of the cylinder 1 through the liquid outlet 10, completing the production process.

[0029] Before unloading, the drain port 3 is opened first, and after the remaining working fluid in the cylinder 1 is emptied, steam is connected to the cylinder 1 to dry the activated alumina balls 12. After drying, the automatic unloader 4 of the activated alumina balls is opened to unload, and the unloaded activated alumina balls 12 are transported to the specified placement point and wait for recycling.
