Description

[0002] In the field of wastewater treatment technology in environmental engineering, chemical wastewater is significantly more difficult to treat than other types of wastewater due to its complex composition, high pollutant concentration, and high toxicity. Traditional wastewater treatment processes often face the problem of low reaction efficiency when dealing with highly stable organic pollutants in chemical wastewater. For example, in the acid-base neutralization process, traditional stirring equipment is difficult to achieve uniform mixing of wastewater and acid / base agents, resulting in incomplete reaction. The pH value needs to be adjusted repeatedly, which increases the treatment cost and time. Therefore, there is a particular need for a catalytic oxidation reaction device for chemical wastewater.

[0003] A search revealed that Chinese patent CN113018967B, published on May 3, 2022, addresses the problem of incomplete cleaning caused by a large amount of impurities adhering to the inner wall of the treatment tank in existing chemical wastewater treatment equipment during practical applications. However, this patent suffers from slow sediment removal, low fluid treatment efficiency, and a lack of reliable anti-backflow devices. If backflow of the reagents occurs, it can not only lead to reaction failure but also cause corrosion damage to the equipment, affecting the safety and stability of the entire treatment process.

[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.

[0029] Please see Figure 1-7 This utility model provides a technical solution: a catalytic oxidation reaction device for chemical wastewater, including a top cover 1, an acid treatment section 2 is provided on the lower surface of the top cover 1, an alkali treatment section 3 is provided on the lower surface of the acid treatment section 2, and an inlet / outlet pipe 4 and a check valve 5 are provided on one side surface of the acid treatment section 2 and the alkali treatment section 3.

[0030] The acid treatment unit 2 includes a protective base 201, which is fixedly connected to the bottom of the top cover 1. An acidification motor 202 is installed on the inner wall of the protective base 201. A first mounting bracket 203 is fixedly connected to the bottom of the protective base 201. A stirring screw 204 is fixedly connected to the output end of the acidification motor 202. A cleaning scraper 205 is fixedly connected to the bottom of the stirring screw 204. An output ring 206, adapted to the cleaning scraper 205, is rotatably connected to the bottom of the stirring screw 204. An acid treatment tank 207 is fixedly connected to the lower surface of the output ring 206. A flow stabilizing pipe 20 is fixedly connected to the bottom of the acid treatment tank 207. 8. With the acid treatment unit 2 in operation, after the external power supply is turned on, the acidification motor 202 drives the stirring screw 204 to rotate, which in turn drives the cleaning scraper 205 to rotate close to the inner wall of the output ring 206. Wastewater and acid enter the acid treatment tank 207 through the inlet and outlet pipes 4. Under the action of the stirring screw 204, they are mixed and reacted. The treated liquid flows into the flow stabilizing pipe 208 through the water outlet of the output ring 206 and is output after the flow rate is stabilized. The acidification motor 202 drives the stirring screw 204 to realize the mixing reaction of wastewater and acid. The cleaning scraper 205 removes impurities from the water outlet of the output ring 206. The flow stabilizing pipe 208 stabilizes the flow rate, ensuring that the acid treatment process is efficient and continuous.

[0031] Furthermore, the alkali treatment unit 3 includes a diversion cone 301, which is attached to the bottom end of the flow stabilizer 208. A second mounting bracket 302 is fixedly connected to the lower surface of the diversion cone 301. A neutralization motor 303 is disposed on the inner surface of the diversion cone 301 and the second mounting bracket 302. A drive shaft 304 is fixedly connected to the output end of the neutralization motor 303. A sedimentation scraper 305 and a linkage shaft 306 are fixedly connected to the lower surface of the drive shaft 304. A track shaft 307 is fixedly connected to the bottom end of the device. A reciprocating base 308 is slidably connected to the outer surface of the track shaft 307. A reciprocating rod 309 is fixedly connected to the bottom end of the reciprocating base 308. A liquid separation slider 310 and a filter block 311 are fixedly connected to the outer surface of the reciprocating rod 309. An isolation sleeve 312 is slidably connected to the inner wall surface of the sedimentation scraper 305. A turbid liquid pipe 313 is opened on one side surface of the isolation sleeve 312. A reciprocating... The reset spring 314 has a sealing plate 315 fixedly connected to one side surface, which is compatible with the turbid liquid pipeline 313. The neutralization tank 316 is fixedly connected to one side surface of the second mounting bracket 302. The bottom end of the isolation sleeve 312 is fixedly connected to the impurity removal valve 317. Through the setting of the alkali treatment section 3, during use, the acidic liquid output from the flow stabilizing pipe 208 diffuses to the neutralization tank 316 through the diversion cone 301. The neutralization motor 303 drives the sedimentation scraper 30 through the drive shaft 304. 5. Rotation, linkage shaft 306 drives track shaft 307 to cause reciprocating base 308 to drive reciprocating rod 309, liquid separation slider 310 and filter pressure block 311 to reciprocate. Turbid liquid is introduced into isolation sleeve 312 through the hole of sedimentation scraper 305 and suction groove, and discharged through turbid liquid pipe 313. Clear liquid is returned through check valve 5 on inner wall of liquid separation slider 310. Flow divider cone 301 evenly disperses liquid. Neutralization motor 303 drives sedimentation scraper 305 and reciprocating mechanism to realize stirring, filtration and discharge of turbid liquid.

[0032] Furthermore, the check valve 5 includes a check sleeve 501, with a limit ring 502 fixedly connected to the inner wall surface of the check sleeve 501. A sealing ring 503 is fixedly connected to the bottom end of the limit ring 502, and a sealing block 504 is attached to one side surface of the sealing ring 503. A return spring 505 adapted to the sealing block 504 is fixedly connected to one side surface of the check sleeve 501. Through the configuration of the check valve 5, during use, the limit ring 502 restricts the movement of the sealing block 504 within the check sleeve 501 of the check valve 5. Within the dynamic range, when the liquid flows in the forward direction, the pressure pushes the sealing block 504 to compress the reset spring 505 to open the channel. When the liquid flows in the reverse direction, the reset spring 505 pushes the sealing block 504 to adhere to the sealing ring 503 to block the fluid, thereby realizing unidirectional flow of liquid in the acid treatment tank 207 and the liquid separation slider 310. By utilizing the dynamic balance between the spring force and the fluid pressure, it is ensured that the liquid in each processing stage of the equipment flows only in the set direction, effectively avoiding reaction failure or equipment damage caused by backflow, and improving the stability and safety of system operation.

[0033] Furthermore, two sets of inlet and outlet pipes 4 are equidistantly arranged on one side surface of the acid treatment tank 207, and two sets of inlet and outlet pipes 4 are equidistantly arranged on one side surface of the neutralization tank 316. Through the arrangement of inlet and outlet pipes 4, during use, the simultaneous injection of chemical wastewater and acid, the stable output of acidic treatment liquid, the injection of alkaline treatment liquid during the neutralization reaction, and the discharge of neutralized liquid and reaction gas can be realized respectively. The symmetrical distribution of multiple sets of pipes ensures the balance of fluid inflow and outflow, avoids excessive load on a single pipe, and improves the equipment processing efficiency and operational stability.

[0034] Furthermore, the outer surface of the output ring 206 is provided with water outlet holes, and multiple sets of water outlet holes are provided on the outer surface of the output ring 206. Through the setting of multiple sets of water outlet holes in the output ring 206, the liquid after reaction in the acid treatment tank 207 can be evenly dispersed to the flow stabilizing pipe 208 during use. The dense distribution of multiple sets of water outlet holes increases the fluid flow area, reduces the liquid flow resistance, avoids excessive local pressure, and at the same time, in conjunction with the structure of the flow stabilizing pipe 208, achieves stable flow rate control, ensuring the uniformity and continuity of the liquid output after acid treatment.

[0035] Furthermore, the cross-section of the flow stabilizer 208 is a three-cone stacked groove, and the bottom of the acid treatment tank 207 is provided with an output hole, the central axis of which coincides with the central axis of the check valve 5. Through the three-cone stacked groove structure of the flow stabilizer 208, the fluid can be divided into multiple slow-flowing fine streams during use, achieving precise control of the flow rate and stable output. The coincidence of the output hole and the central axis of the check valve 5 ensures that the liquid can pass smoothly through the check valve 5 in a straight line, reducing flow resistance and energy loss, effectively preventing backflow, and ensuring the stability of equipment operation and the high efficiency of fluid transmission.

[0036] Furthermore, a reflux hole is provided on one side surface of the isolation sleeve 312, and three sets of turbid liquid pipes 313 are symmetrically arranged around the central axis of the isolation sleeve 312. Through the reflux hole of the isolation sleeve 312, during use, the reflux hole allows the filtered clear liquid to flow back to the neutralization tank 316 through the check valve 5 on the inner wall of the separator slider 310, realizing liquid circulation treatment. The three sets of symmetrically distributed turbid liquid pipes 313 increase the turbid liquid discharge efficiency, ensure timely separation of precipitates, and the symmetrical structure can also balance fluid pressure, avoid local blockage, and improve the overall treatment efficiency of the alkali treatment unit 3.

[0037] Furthermore, the sedimentation scraper 305 has holes on one side surface, and multiple sets of holes are equally spaced on one side surface of the sedimentation scraper 305. With the multiple sets of holes in the sedimentation scraper 305, during use, the precipitate generated by the neutralization reaction can enter the suction tank through the holes under the action of centrifugal force, and then be discharged through the isolation sleeve 312. The dense distribution of multiple sets of holes increases the suction area of ​​the precipitate, improves the solid-liquid separation efficiency, and ensures that the sedimentation scraper 305 can both stir the liquid to promote the reaction during rotation and promptly discharge the precipitate to avoid damage to the equipment caused by deposition.

[0038] Furthermore, the sedimentation scraper 305 has a "U"-shaped cross-section in the vertical direction, and a suction groove is formed on the inner wall surface of the sedimentation scraper 305. The suction groove is interconnected with multiple sets of holes. Through the connection between the vertical cross-section of the sedimentation scraper 305 and multiple sets of holes, the negative pressure zone formed by the "U"-shaped structure can enhance the adsorption capacity of the sediment during use. The interconnected design of the suction groove and holes allows the sediment to flow smoothly into the isolation sleeve 312 after entering the suction groove through the holes, achieving efficient solid-liquid separation. At the same time, it avoids the accumulation of sediment on the scraper surface, ensuring the continuous and stable operation of the stirring and filtering functions.

[0039] Furthermore, check valves 5 are installed on the inner wall surfaces of the acid treatment tank 207 and the liquid separation slider 310. Six sets of check valves 5 are symmetrically arranged around the central axis of the liquid separation slider 310. Through the installation of check valves 5, the check valves 5 in the acid treatment tank 207 can prevent acid from flowing back into the feed pipe during use. The six sets of check valves 5 symmetrically distributed at the liquid separation slider 310 can ensure that the clear liquid flows back to the neutralization tank 316 in one direction. The symmetrical layout makes the fluid pressure in all directions balanced. The multiple sets of valves enhance the reliability of backflow prevention, avoid system failure due to local valve failure, and ensure the stability and safety of the unidirectional flow of the entire processing process.

[0040] Working Principle: When the equipment starts running, an external power supply powers the entire system. During operation, chemical wastewater and treated acid are simultaneously injected into the acid treatment tank 207 through the inlet and outlet pipes 4. The acidification motor 202 drives the stirring spiral 204 to rotate at high speed, and the cleaning scraper 205 rotates synchronously against the inner wall of the output ring 206. Through precise matching size design, it effectively removes solid impurities adhering to the periphery of multiple sets of water outlets on the side wall of the output ring 206, avoiding the risk of blockage. Under the strong stirring of the stirring spiral 204, the wastewater and acid are fully mixed and undergo a neutralization reaction. The generated acidic preliminary treatment liquid is collected at the bottom of the acid treatment tank 207 through the water outlet of the output ring 206, and then flows through the unique flow stabilizing pipe 208. The three-cone stacked groove structure divides the fluid into multiple slowly flowing fine streams, achieving precise flow rate control and stable output. The acidic liquid, after flow stabilization treatment, enters the alkali treatment section 3. The diverting cone 301 evenly diffuses the liquid into the neutralization tank 316, while the alkaline treatment liquid is injected through the bottom inlet / outlet pipe 4. The two solutions undergo a neutralization reaction, causing metal ions in the wastewater to combine with hydroxide ions to form insoluble precipitates. The gas produced by the reaction is promptly discharged through the top inlet / outlet pipe 4. The neutralization motor 303 drives the drive shaft 304 to rotate the sedimentation scraper 305. Its equidistantly distributed porous structure works in conjunction with the suction tank to draw in the turbid liquid containing precipitates and guide it into the isolation sleeve 312. After passing through three sets of... Symmetrically distributed turbid liquid pipes 313 discharge the liquid. A reset spring 314 and a sealing plate 315 form an automatic sealing system, quickly closing the pipes when there is no turbid liquid flow. A linkage shaft 306 drives the track shaft 307 to rotate, driving the reciprocating base 308 to reciprocate axially. This causes the liquid separation slider 310 and the filter block 311 to circulate and filter the neutralized turbid liquid. The filtered clear liquid flows back to the neutralization tank 316 through six sets of check valves 5 on the inner wall of the liquid separation slider 310 via return holes. Solid precipitates accumulate in the isolation sleeve 312 and can be periodically cleaned by the impurity removal valve 317. The check valves 5, as the core component for preventing backflow, are installed on the inner walls of the acid treatment tank 207 and the liquid separation slider 310, respectively, to prevent backflow. The limiting ring 502, sealing ring 503, sealing block 504, and return spring 505 inside the housing 501 form a precise linkage structure. When the liquid flows in the forward direction, the pressure pushes the sealing block 504 to compress the return spring 505 and open the channel. When the liquid flows in the reverse direction, the return spring 505 pushes the sealing block 504 to tightly fit the sealing ring 503. With the precise limiting of the limiting ring 502, six symmetrically distributed check valves 5 ensure that the liquid always maintains unidirectional flow throughout the entire treatment process, effectively ensuring the safety and stability of the equipment operation. The acidification motor 202 and the neutralization motor 303 are model YE2-132S-4. This completes the use process of a catalytic oxidation reaction equipment for chemical wastewater.
