Abstract
Description
Technical Field
[0001] This utility model relates to the technical field, specifically to a device for treating alkaline liquid from sulfurized black tail gas. Background Technology
[0002] Sulfur black dyes are commonly used in the dyeing process of textiles, especially dark dyes. This dyeing process generates toxic sulfur gases and alkaline waste liquids. Sulfur gases (such as hydrogen sulfide) are harmful to the environment and human health. Therefore, the exhaust gases generated during the dyeing process need to be treated by a washing system. Alkaline solutions (such as sodium hydroxide solution) are usually used to absorb the acidic components in the exhaust gases.
[0003] Firstly, when treating waste liquid, if the acidity or alkalinity of the waste liquid is not suitable, it will affect the oxidation and flocculation effects, which may lead to low efficiency of subsequent reactions.
[0004] Secondly, the absence of an oxidation step may prevent the flocculant from effectively binding with pollutants in the wastewater, thus affecting the removal of solid particles and ultimately leading to incomplete wastewater treatment.
[0005] Finally, without adsorption and oxidation functions, harmful gases will be directly released into the air during the waste liquid oxidation process, which may lead to serious air and environmental pollution. Utility Model Content

[0028] 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. Example
[0029] Please see Figures 1-5A device for treating alkaline liquid from sulfurized black tail gas includes a main body 1, a mixing mechanism, and an operating mechanism. The mixing mechanism includes a motor 2, a stirring shaft 3, a mixing component 4, a positioning component 5, and auxiliary components. The motor 2 is fixedly mounted on the main body 1. The stirring shaft 3 is mounted on the output end of the motor 2. The mixing component 4 is mounted on the stirring shaft 3 and rotatably connected to the stirring shaft 3. The positioning component 5 is fixedly mounted on the bottom of the main body 1 and rotatably connected to the stirring shaft 3. The auxiliary components include a control valve 6, a delivery pump 7, and a transmission pipe 8. The control valve 6 is fixedly mounted on the bottom of the positioning component 5. The delivery pump 7 is fixedly connected to the positioning component 5. One end of the transmission pipe 8 is fixedly connected to the delivery pump 7, and the other end is fixedly connected to the main body 1.
[0030] In this embodiment, the mixing mechanism includes a motor 2, a stirring shaft 3, a mixing component 4, a positioning component 5, and auxiliary components. In use, the waste liquid and the neutralizing liquid can be transported into the pretreatment chamber 14 of the main body 1 through the tail liquid pipe 16 and the drain pipe, respectively. Then, the motor 2 drives the stirring shaft 3 to rotate, and the mixing component 4 on the stirring shaft 3 can rotate in the mixture, making the mixing of the mixture more thorough. When mixing the mixture, the stirring shaft 3 rotates in the rotation port 19 in the positioning component 5. After mixing is completed, the control valve 6 can be opened and the delivery pump 7 can be started, so that the mixture enters the transmission pipe 8 through the drain port 18 and finally directly enters the oxidation chamber 15, thereby oxidizing and flocculating the waste liquid after the neutralization reaction.
[0031] In this embodiment, the operating mechanism includes a compressor 9, a gas delivery pipe 10, a base 11, activated carbon 12, and a mounting bracket 13. In use, firstly, the sealing plug 23 installed on the sealing pipe 21 needs to be opened, allowing the sealing gasket 24 and the sealing pipe 21 to be loosened from a sealed connection. Then, flocculant is poured into the sealing pipe 21. At this time, the compressor 9 can be started, allowing it to draw in air from the outside and discharge the air into the mixture through the outlet 20 in the gas delivery pipe 10. This ensures that the coagulant is evenly distributed in the mixture. The mixture is oxidized to produce new compounds, which are eventually flocculated by the flocculant and settled in the base 11 installed at the bottom of the oxidation chamber 15. During the oxidation process, the sealing plug 23 is reinstalled on the sealing tube 21, and any gas that may escape is finally purified by the activated carbon 12 (or, depending on the type of gas, activated alumina or other substances) installed on the mounting bracket 13 on the exhaust pipe 22 to absorb harmful gases or adsorb odor gases. The final flocculated material is then discharged from the main body 1 through the discharge pipe 25 and filtered by other devices. Example
[0032] In summary, during use, the waste liquid and neutralizing liquid can be fed into the pretreatment chamber 14 of the main body 1 through the tail liquid pipe 16 and the drain pipe, respectively. Then, the motor 2 drives the stirring shaft 3 to rotate, and the mixing component 4 on the stirring shaft 3 rotates in the mixture, making the mixing more thorough. While mixing, the stirring shaft 3 rotates in the rotation port 19 of the positioning component 5. After mixing, the control valve 6 can be opened, and the delivery pump 7 starts, allowing the mixture to enter the transmission pipe 8 through the drain port 18 and finally directly into the oxidation chamber 15, thus oxidizing and flocculating the waste liquid after the neutralization reaction. When flocculation is required, the sealing plug 23 installed on the sealing pipe 21 must first be opened, so that the sealing gasket 24 and the sealing pipe 21 are aligned. The sealed connection can be released, and then flocculant is poured into the sealed tube 21. At this time, the compressor 9 can be started, so that the compressor 9 draws in air from the outside and discharges the air into the mixture through the air outlet 20 in the air supply pipe 10. This allows the coagulant to be evenly distributed in the mixture. The mixture is oxidized to produce new compounds, which are eventually flocculated by the flocculant and finally settled in the base 11 installed at the bottom of the oxidation chamber 15. During the oxidation process, the sealing plug 23 is reinstalled on the sealed tube 21, and any gas that may escape is finally purified by the activated carbon 12 (or by activated alumina or other substances depending on the type of gas) installed on the mounting bracket 13 on the exhaust pipe 22 to absorb harmful gases or adsorb odor gases. The final flocculated material is discharged from the outside of the main body 1 through the discharge pipe 25 and filtered by other devices.

For all the fixed connections mentioned above, welding is preferred.
