Description

Technical Field

[0001] This utility model belongs to the field of hydrogen peroxide production technology, specifically relating to a flash tank for hydrogen peroxide working fluid. Background Technology

[0002] In traditional hydrogen peroxide production processes, flash tanks are not used, and the circulating working fluid continuously carries water, severely impacting catalyst efficiency and production efficiency. With continuous process improvement and innovation, two-person flash tanks have been introduced into hydrogen peroxide production. Gradually, flash tanks have become a key piece of equipment in hydrogen peroxide production. The working fluid dehydration equipment in hydrogen peroxide production is generally called a flash tank, primarily used in fixed-bed palladium catalyst hydrogen peroxide production processes.

[0003] Currently, most existing flash tanks use simple branched distribution pipes to distribute the working liquid. Due to the overly simple structure of the branched distribution pipes, the liquid distribution cannot be uniform, resulting in low equipment efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a flash tank for hydrogen peroxide working fluid to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a flash tank for hydrogen peroxide working fluid, comprising a flash tank body and a liquid inlet mechanism, wherein the liquid inlet mechanism comprises a main liquid inlet pipe fixedly connected to the top of the flash tank body, a distribution pipe rotatably connected to the lower end of the main liquid inlet pipe, a distribution branch pipe annularly distributed around the distribution pipe, an atomizing nozzle evenly arranged at the bottom of the distribution branch pipe, and a drive assembly for driving the distribution pipe to rotate.

[0006] All the distribution branches are connected to a common connecting ring at the end away from the liquid separator. A support ring is fixedly connected to the inner wall of the flash tank body, and the connecting ring is slidably connected to the support ring.

[0007] In a preferred embodiment, the drive assembly includes a motor fixedly mounted on the outer wall of the flash tank body, a rotating shaft fixedly connected to the output end of the motor, a bevel gear fixedly connected to one end of the rotating shaft, and a bevel gear ring fixedly fitted on the liquid separator tube to mesh with the bevel gear.

[0008] In a preferred embodiment, a protective shell is fixedly connected to the inner wall of the flash tank body, and the rotating shaft, bevel gear and bevel gear ring are all disposed inside the protective shell.

[0009] In a preferred embodiment, the liquid distribution pipe is connected to the main liquid inlet pipe via a rotary joint.

[0010] In a preferred embodiment, an air outlet is fixedly connected to one side of the top of the flash tank body, and a filter plate is fixedly connected to the lower end of the air outlet.

[0011] In a preferred embodiment, a liquid outlet is fixedly connected to the bottom of the flash tank body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This hydrogen peroxide working fluid flash tank, through the addition of a liquid inlet mechanism, can activate the drive assembly during liquid inlet to rotate the distribution pipe, which in turn drives the distribution branch pipes in a circular motion. This, in turn, drives the atomizing nozzles in a circular motion, expanding the liquid distribution range of the atomizing nozzles. After the hydrogen peroxide working fluid is added from the main inlet pipe, it passes through the distribution pipes into each distribution branch pipe and is evenly sprayed from the atomizing nozzles at the bottom of the distribution branch pipes into the flash tank, resulting in more uniform liquid distribution and improved equipment efficiency.

[0014] This hydrogen peroxide working fluid flash tank, by setting a connecting ring and a support ring, allows the dispensing pipe to slide along the support ring as it moves in a circular motion, thereby providing stable support for the dispensing pipe and improving its stability.

Detailed Implementation

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figure 1-3 This utility model provides a flash tank for hydrogen peroxide working solution, including a flash tank body 1 and a liquid inlet mechanism 2. The liquid inlet mechanism 2 includes a main liquid inlet pipe 21 fixedly connected to the top of the flash tank body 1, a distribution pipe 22 rotatably connected to the lower end of the main liquid inlet pipe 21, distribution branch pipes 23 annularly distributed around the distribution pipes 22, atomizing nozzles 24 evenly arranged at the bottom of the distribution branch pipes 23, and a drive assembly 25 for driving the distribution pipes 22 to rotate. The distribution pipes 22 and the main liquid inlet pipe 21 are connected by a rotary joint 28. By setting up the liquid inlet mechanism 2, when liquid is being added, the drive assembly 25 can be activated to drive the distribution pipe 22 to rotate, causing the distribution pipe 22 to drive the distribution branch pipe 23 to move in a circular motion, which in turn drives the atomizing nozzle 24 to move in a circular motion, expanding the liquid distribution range of the atomizing nozzle 24. After the hydrogen peroxide working fluid is added from the liquid inlet main pipe 21, it enters each distribution branch pipe 23 through the distribution pipe 22 and is evenly sprayed out from the atomizing nozzle 24 at the bottom of the distribution branch pipe 23 into the flash tank, making the liquid distribution more uniform and improving the working efficiency of the equipment.

[0022] Specifically, the drive assembly 25 includes a motor 251 fixedly installed on the outer wall of the flash tank body 1. The output end of the motor 251 is fixedly connected to a rotating shaft 252. One end of the rotating shaft 252 is fixedly connected to a bevel gear 253. A bevel gear ring 254 that meshes with the bevel gear 253 is fixedly fitted on the liquid distribution pipe 22. By setting the drive assembly 25, the motor 251 can be started to drive the rotating shaft 252 to rotate, which in turn drives the bevel gear 253 to rotate, which in turn drives the bevel gear ring 254 to rotate, which in turn drives the liquid distribution pipe 22 to rotate.

[0023] The flash tank body 1 has a protective shell 255 fixedly connected to its inner wall. The rotating shaft 252, bevel gear 253 and bevel gear ring 254 are all set inside the protective shell 255. By setting the protective shell 255, the rotating shaft 252, bevel gear 253 and bevel gear ring 254 can be isolated and protected.

[0024] Furthermore, all the distribution branches 23 are connected to a connecting ring 26 at the end away from the liquid distribution pipe 22. A support ring 27 is fixedly connected to the inner wall of the flash tank body 1. The connecting ring 26 and the support ring 27 are slidably connected. By setting the connecting ring 26 and the support ring 27, when the liquid distribution pipe 22 moves in a circular motion, the liquid distribution pipe 22 will drive the connecting ring 26 to slide along the support ring 27, thereby providing stable support for the liquid distribution pipe 22 and improving the stability of the liquid distribution pipe 22.

[0025] The flash tank body 1 has a gas outlet 11 fixedly connected to one side of the top. By setting the gas outlet 11, the separated gas can be discharged. The lower end of the gas outlet 11 is fixedly connected to a filter plate 12. By setting the filter plate 12, the liquid can be prevented from being discharged from the gas outlet 11. The bottom of the flash tank body 1 is fixedly connected to a liquid outlet 13. By setting the liquid outlet 13, the working raffinate in the flash tank can be discharged.

[0026] The working principle and usage process of this utility model are as follows: First, during liquid inlet, the motor 251 can be started to drive the rotating shaft 252 to rotate, which in turn drives the bevel gear 253 to rotate, which in turn drives the bevel gear ring 254 to rotate, which in turn drives the distribution pipe 22 to rotate, which in turn drives the distribution branch pipe 23 to move in a circular motion, which in turn drives the atomizing nozzle 24 to move in a circular motion, thus expanding the liquid distribution range of the atomizing nozzle 24. After the hydrogen peroxide working solution is added from the main liquid inlet 21, it enters each distribution branch pipe 23 through the distribution pipe 22 and is evenly sprayed from the atomizing nozzle 24 at the bottom of the distribution branch pipe 23 into the flash tank, making the liquid distribution more uniform and improving the working efficiency of the equipment.
