The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] An embodiment of the present utility model provides an acid distributor with uniform acid distribution, as Figures 1-5 shown, the acid distributor with uniform acid distribution includes: a filter barrel 1 and a shunt tank 3, the shunt tank 3 is arranged below the filter barrel 1; a conduit 2, the conduit 2 is fixedly communicated with the bottom of the filter barrel 1, and the liquid outlet end of the conduit 2 extends into the shunt tank 3; a plurality of overflow holes 4, the plurality of overflow holes 4 are symmetrically arranged on the shunt tank 3, and the liquid outlet end of the corresponding overflow hole 4 is fixedly installed with an acid outlet pipe 5, and the liquid outlet end of the acid outlet pipe 5 is provided with a shower head 6; a detachable barrel cover 7, the barrel cover 7 is arranged on the filter barrel 1; a filter collection mechanism for filtering acid liquid and collecting impurities, the filter collection mechanism is arranged on the filter barrel 1.

[0023] In this embodiment, the filter barrel 1 serves as the upper component of the acid distributor, which is used to preliminarily filter the concentrated sulfuric acid entering the acid distributor, remove large particle impurities therein, and ensure the purity of subsequent acid distribution. The conduit 2 is fixedly connected to the bottom of the filter barrel 1 to guide the preliminarily filtered concentrated sulfuric acid to the shunt tank 3 below. The design of the conduit 2 ensures that the concentrated sulfuric acid can smoothly enter the shunt tank 3, reducing the flow resistance. The shunt tank 3 is arranged below the filter barrel 1 to receive the concentrated sulfuric acid from the conduit 2. Its internal structure is reasonably designed to evenly distribute the concentrated sulfuric acid to each acid outlet point. A plurality of overflow holes 4 are symmetrically opened on the shunt tank 3 and are in the same plane to ensure that the concentrated sulfuric acid can flow out evenly from multiple points. This symmetrical design helps to achieve uniform distribution of the concentrated sulfuric acid in the tower. The acid outlet pipe 5 is fixedly installed at the liquid outlet end corresponding to the overflow hole 4 to further guide the concentrated sulfuric acid to the packing layer in the tower. The number of the acid outlet pipes 5 corresponds to that of the overflow holes 4, ensuring that each acid distribution point can obtain an equal amount of concentrated sulfuric acid. The shower head 6 is arranged at the liquid outlet end of the acid outlet pipe 5, and through its special structure, the concentrated sulfuric acid is sprayed out in the form of finer droplets, increasing the contact area with the process gas and improving the absorption efficiency. The detachable barrel cover 7 is arranged on the filter barrel 1, which is convenient for cleaning and maintaining the inside of the filter barrel 1, and at the same time ensures that the acid distributor is in a sealed state during operation to prevent acid mist from leaking. The filtering and collecting mechanism is arranged on the filter barrel 1, which is used to further filter fine impurities in the acid liquid and collect these impurities for subsequent treatment. The existence of this mechanism effectively extends the service life of the acid distributor and ensures the purity of acid distribution. By increasing the number of acid distribution points (i.e., a plurality of overflow holes 4) and realizing their symmetrical distribution, the acid distributor of the present utility model can significantly improve the uniformity of the distribution of concentrated sulfuric acid in the tower, ensuring that each acid distribution point can obtain an equal amount of concentrated sulfuric acid. The design of the shower head 6 makes the concentrated sulfuric acid spray out in the form of finer droplets, increasing the contact area with the process gas, thereby improving the gas absorption rate.

[0024] In a further preferred embodiment of the present utility model, the filtering and collecting mechanism includes: a mesh plate 9 inclined in the filter barrel 1; a filter paper 10 arranged on the mesh plate 9 for filtering acid liquid impurities; a collecting cavity 11 arranged on the filter barrel 1; and a collecting box 12 slidably installed in the collecting cavity 11.

[0025] In this embodiment, to further improve the filtering effect and maintenance convenience of the acid distributor, the filtering and collecting mechanism is optimized. The mesh plate 9 is inclined in the filter barrel 1, and its inclination angle is properly designed, which helps the acid liquid to fully contact the mesh plate 9 during the flow process, so as to more effectively filter out the impurities in the acid liquid. At the same time, the inclined setting can also promote the natural deposition of impurities on the mesh plate 9, facilitating subsequent cleaning. The filter paper 10 is arranged on the mesh plate 9 as the main filtering medium. The filter paper 10 has high filtering accuracy and good chemical stability, and can effectively intercept the fine particles and suspended substances in the acid liquid to ensure the purity of the acid distribution. In addition, the filter paper 10 can be replaced according to actual needs to maintain the filtering effect. The collecting cavity 11 is arranged on the filter barrel 1 and is used in cooperation with the mesh plate 9 and the filter paper 10. The design of the collecting cavity 11 enables the impurities intercepted by the mesh plate 9 and the filter paper 10 to smoothly fall into it, avoiding the accumulation and blockage of impurities in the filter barrel 1. The collecting box 12 is slidably installed in the collecting cavity 11 for collecting the filtered impurities. The design of the collecting box 12 makes the cleaning and collection of impurities more convenient and efficient. When the impurities in the collecting box 12 accumulate to a certain extent, it only needs to be slid out of the collecting cavity 11 and cleaned, without disassembling the entire filter barrel 1. Through the dual filtering effect of the mesh plate 9 and the filter paper 10, the purity of the acid liquid is further improved, ensuring the full contact and efficient absorption of concentrated sulfuric acid and process gas during the acid distribution process. The sliding installation design of the collecting box 12 makes the cleaning work of impurities simple and fast, reducing the maintenance cost and time cost. At the same time, the replaceability of the filter paper 10 also ensures the continuity and stability of the filtering effect.

[0026] In a further preferred embodiment of the present utility model, a liquid guiding channel is arranged on the barrel cover 7, and an acid inlet pipe 8 is fixedly connected to the top of the liquid guiding channel, and the acid inlet pipe 8 is used to connect the acid injection device.

The liquid guiding channel is cleverly arranged on the barrel cover 7, and its design ensures that the concentrated sulfuric acid entering from the acid inlet pipe 8 can flow smoothly and unobstructedly into the interior of the filter barrel 1. The existence of the liquid guiding channel avoids the splashing and leakage of concentrated sulfuric acid during the injection process, ensuring the safety of the operator and the cleanliness of the production environment. The acid inlet pipe 8 is fixedly connected to the top of the liquid guiding channel as the interface for connecting the acid injection device.

[0028] In a further preferred embodiment of the present utility model, a detachable buffer plate 13 is arranged in the liquid guiding channel, a plurality of through holes 14 are formed in the buffer plate 13, and a sealing plate 15 is fixedly installed on the buffer plate 13.

At the same time, a sealing plate 15 is fixedly installed. This innovative design brings beneficial effects in many aspects. The buffer plate 13, as a key component in the liquid guide channel, can effectively slow down the flow rate of concentrated sulfuric acid from the acid inlet pipe 8 into the filter barrel 1, making it enter the acid distribution system more smoothly. This buffering effect helps to reduce the impact and fluctuation generated during the injection of concentrated sulfuric acid, protecting the filter barrel 1 and its internal components from sudden pressure changes. The through holes 14, a number of through holes 14 are opened on the buffer plate 13, providing multiple dispersed inflow channels for concentrated sulfuric acid. The distribution and size of these through holes 14 are carefully designed to ensure that concentrated sulfuric acid can pass through the buffer plate 13 evenly and stably and continue to flow downward into the filter barrel 1. The sealing plate 15, the sealing plate 15 fixedly installed on the buffer plate 13, plays a role in enhancing the sealing performance. The design of the sealing plate 15 ensures a tight fit between the buffer plate 13 and the inner wall of the liquid guide channel, preventing concentrated sulfuric acid from leaking through the gaps during the injection process.

Its main function is to discharge the retained acid liquid in the shunt tank 3. Electric control valves 16 are provided on both the drain pipe 17 and the conduit 2, realizing precise control of the acid liquid flow. The electric control valve has the characteristics of fast response speed and high control precision, and can automatically adjust the opening of the valve or completely close the electric control valve 16 according to production requirements.

[0032] In a further preferred embodiment of the present utility model, hooks for positioning are symmetrically and fixedly installed on the barrel cover 7, and buckles are symmetrically and fixedly installed on the filter barrel 1, and the buckles are latched with the corresponding hooks.

[0033] In this embodiment, in order to improve the connection stability and sealing performance between the filter barrel 1 and the barrel cover 7, hooks for positioning are symmetrically and fixedly installed on the barrel cover 7. At the same time, buckles matching them are symmetrically and fixedly installed on the filter barrel 1. After the buckles and the hooks are latched, the barrel cover 7 can be limited in position and displacement can be prevented.

[0034] In a further preferred embodiment of the present utility model, assembly frames for positioning are symmetrically and fixedly installed on the shunt tank 3, and bolts that can be assembled in a drying tower or an absorption tower are provided on the assembly frames.

[0035] In this embodiment, the assembly frame is symmetrically and fixedly installed on the flow splitting tank 3. This symmetrical design helps to ensure that the flow splitting tank 3 can maintain balance when installed on the drying tower or absorption tower, reducing vibration or deviation caused by improper installation. The main function of the assembly frame is to provide positioning support to ensure that the flow splitting tank 3 can be accurately installed in the predetermined position.
