Description

Technical Field

[0001] This utility model relates to the field of crude chlorobutyric acid water separation, and in particular to a crude chlorobutyric acid water separation system. Background Technology

[0002] In the production of chloroprene, the drying of crude chloroprene is a crucial step in ensuring product quality. In the traditional process, crude chloroprene is dried in a drying tower, where anhydrous calcium chloride is used to absorb the moisture, and acidic water is manually separated from the bottom of the drying tower.

[0003] Currently, traditional methods for separating crude chlorobutyric acid from acidic water mainly include static stratification, centrifugation, and ordinary filtration. However, these methods have many limitations in practical applications. Static stratification relies on the density difference between materials to achieve separation, but the separation efficiency is extremely low and is greatly affected by factors such as ambient temperature and material viscosity, making it difficult to meet the needs of continuous industrial production. Centrifugation can improve the separation speed to some extent, but the equipment consumes a lot of energy, and the separation effect is poor for mixtures containing fine solid impurities, easily causing impurity residues and affecting the purity of subsequent products. Ordinary filtration uses conventional filter cloth or filter paper as the filter media, which has limited filtration precision and cannot effectively intercept small particulate impurities. At the same time, the filter media is prone to clogging and needs to be replaced frequently, which not only increases production costs but also leads to production interruptions and reduces production continuity. In addition, crude chlorobutyric acid has a certain degree of chemical activity. If it comes into full contact with air during the separation process, it is prone to oxidation, leading to product deterioration and affecting its performance. At the same time, if the acidic water is not properly treated and directly discharged, it will cause serious environmental pollution, which does not meet the environmental protection requirements of modern green chemical production. Therefore, it is necessary to provide a new crude chlorobutyric acid water separation system to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a crude chlorobutyric acid water separation system.

[0005] The crude chloroprene acid water separation system provided by this utility model includes: a crude chloroprene buffer tank, an acid water separator on one side of the crude chloroprene buffer tank, the acid water separator adopting coalescing membrane separation technology; an acid water storage tank on one side of the acid water separator, and an acid feed tank for the first acid removal tower at one end of the acid water separator; an acid water collection tank below the acid water storage tank; and an acid water filter, an acid water filter pump, and a post-pump filter are sequentially connected between the bottom of the crude chloroprene buffer tank and one side of the acid water separator via a pipeline.

[0006] Preferably, nitrogen gas is introduced into the top of both the crude chloroprene buffer tank and the acid water separator through pipelines. The top of the crude chloroprene buffer tank is fixedly connected to the feed pipe, which is connected to the outlet of the concentration tower condenser.

[0007] Preferably, a radar level gauge is fixedly connected to the top of the crude chloroprene buffer tank, which is used to observe the liquid level inside the crude chloroprene buffer tank.

[0008] Preferably, the bottom of the acid water separator is connected to the top of the acid water storage tank via a pipe; one side of the bottom of the acid water separator is connected to the feed tank of the acid desulfurization tower via a pipe.

[0009] Preferably, the acid water storage tank discharges acid water into the deacidification water collection tank through a pipe at the bottom.

[0010] Preferably, the post-pump filter consists of a lower housing, an upper housing, a clamping plate, a filter plate, and a limiting assembly; the upper housing is fixedly installed above the lower housing through the limiting assembly, the clamping plate symmetrically fixes the inner walls on both sides of the lower housing, and the filter plate is inserted into the clamping plate; pipes are clamped to both sides of the upper housing and the lower housing.

[0011] Preferably, the limiting component includes: a first limiting block, which is symmetrically and fixedly installed on the outer walls of both sides of the lower housing, and a limiting box is fixedly connected to both outer walls of the upper housing. Spring pieces are symmetrically installed inside the limiting boxes, with the top of the spring pieces fixed to the limiting boxes and the bottom of the spring pieces fixedly connected to a second limiting block, which engages with the first limiting block.

[0012] Preferably, a slider is installed inside the limiting box between the two spring pieces, and both ends of the slider are in contact with the spring pieces; a lever is fixedly connected to one side of the slider, and the lever is slidably connected to the limiting box.

[0013] Compared with related technologies, the crude chlorobutyric acid water separation system provided by this utility model has the following beneficial effects: I. Improve separation efficiency and quality, and optimize separation results The acid-water separator in this system employs coalescing membrane separation technology. Leveraging the selective permeability of the membrane, it efficiently separates crude chlorobutyric acid and acidic water. Compared to the traditional static stratification method, this significantly shortens the separation time and dramatically improves separation efficiency. Simultaneously, the bottom of the crude chlorobutyric acid buffer tank is sequentially connected to an acidic water filter, an acidic water filter pump, and a post-pump filter. The post-pump filter effectively intercepts solid impurities in the material, solving the problem of poor separation of fine impurities in traditional centrifugal separation and ordinary filtration methods. This results in a significant improvement in the purity of the separated crude chlorobutyric acid and the cleanliness of the acidic water. II. Ensure product quality and reduce material deterioration. Both the crude chloroprene buffer tank and the acid-water separator have nitrogen gas piped into their tops to create an inert protective atmosphere. This design effectively prevents the crude chloroprene acid from oxidizing and deteriorating upon contact with air, overcoming the defects of product quality degradation caused by material oxidation in traditional separation processes. This maximizes the chemical stability and performance of the crude chloroprene acid. In addition, the radar level gauge on the top of the crude chloroprene buffer tank can monitor the liquid level in the tank in real time, facilitating precise control by operators and further ensuring the stability of the production process, indirectly improving product quality. Third, it is easy to operate and maintain, reducing production costs. The post-pump filter consists of a lower housing, an upper housing, a clamping plate, a filter plate, and a limiting assembly. The limiting assembly, through the cooperation of a first limiting block, a limiting box, a spring, a second limiting block, a slider, and a lever, enables convenient disassembly and assembly of the upper and lower housings, facilitating filter plate replacement. Compared to the cumbersome filter media replacement issues of traditional ordinary filtration methods, this design reduces production downtime caused by filter media replacement, lowers operational difficulty and maintenance costs, and improves production continuity. Fourth, it is environmentally friendly and energy-saving, and meets production requirements. A portion of the acid water separated by the acid water separator in the system enters the acid water storage tank. Below the acid water storage tank is a deacidification water collection tank. The acid water can be discharged into the deacidification water collection tank through pipelines, realizing the classified collection and centralized treatment of acid water, avoiding direct discharge and pollution to the environment, and meeting the environmental protection requirements of green chemical production. At the same time, compared with the energy-intensive centrifugal separation method, the overall energy consumption of this system is lower, which is conducive to reducing energy consumption in the production process. V. Achieve continuous production to meet industrialization needs The crude chloroprene buffer tank can temporarily store materials from the condenser of the concentration tower, acting as a buffer. Combined with the orderly connection between various components, the entire system can achieve continuous industrial production, solving the problem that traditional separation methods cannot meet the needs of large-scale production and further improving production efficiency.

It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0018] Please see Figures 1 to 4 A crude chloroprene acid water separation system includes: a crude chloroprene buffer tank 1; an acid-water separator 2 with coalescing membrane separation technology on one side of the crude chloroprene buffer tank 1; an acid-water storage tank 3 with one side of the acid-water separator 2; an acid feed tank 4 with one end of the acid-water separator 2; an acid-water collection tank 5 below the acid-water storage tank 3; and an acid-water filter 6, an acid-water filter pump 7, and a post-pump filter 8 connected sequentially by pipes between the bottom of the crude chloroprene buffer tank 1 and one side of the acid-water separator 2. Nitrogen gas is introduced into the top of both the crude chloroprene buffer tank 1 and the acid water separator 2 through pipelines. The top of the crude chloroprene buffer tank 1 is fixedly connected to the feed pipe 9, which is connected to the outlet of the condenser of the concentration tower. The top of the crude chloroprene buffer tank 1 is fixedly connected to the radar level gauge 10, which is used to observe the liquid level inside the crude chloroprene buffer tank 1. The bottom of the acid water separator 2 is connected to the top of the acid water storage tank 3 through a pipeline. One side of the bottom of the acid water separator 2 is connected to the feed tank 4 of the acid desulfurization tower through a pipeline. The bottom of the acid water storage tank 3 discharges the acid water into the acid desulfurization collection tank 5 through a pipeline.

[0019] It should be noted that the acid water separator 2 adopts coalescing membrane separation technology, and the acid water is continuously and automatically separated from the bottom of the acid water separator 2 and flows into the acid water storage tank 3.

[0020] Please see Figures 2 to 4The post-pump filter 8 consists of a lower housing 11, an upper housing 12, a clamping plate 13, a filter plate 14, and a limiting assembly. The upper housing 12 is fixedly installed above the lower housing 11 via the limiting assembly. The clamping plate 13 symmetrically fixes the inner walls of both sides of the lower housing 11, and the filter plate 14 is inserted into the clamping plate 13. Pipes are clamped to both sides of the upper housing 12 and the lower housing 11. The limiting assembly includes a first limiting block 15, which is symmetrically fixedly installed on the outer walls of both sides of the lower housing 11, and the upper housing 12 is fixedly installed on both sides of the lower housing 11. Limiting boxes 16 are fixedly connected to the outer side walls. Spring pieces 17 are symmetrically installed inside the limiting boxes 16. The top of the spring pieces 17 is fixed to the limiting box 16, and the bottom of the spring pieces 17 is fixedly connected to a second limiting block 18. The second limiting block 18 is engaged with the first limiting block 15. A slider 19 is installed inside the limiting box 16 between the two spring pieces 17. Both ends of the slider 19 are in contact with the spring pieces 17. A lever 20 is fixedly connected to one side of the slider 19. The lever 20 is slidably connected to the limiting box 16.

[0021] It should be noted that when the upper lever 20 moves the slider 19 upward, the lever 20 will squeeze the spring piece 17, causing the two spring pieces 17 to move away from each other, thereby releasing the engagement between the first limiting block 15 and the second limiting block 18.

[0022] The working principle of the crude chlorobutyric acid water separation system provided by this utility model is as follows: First, the material is introduced and buffered. The mixture containing crude chlorobutyric acid and acidic water from the outlet of the concentration tower condenser enters the crude chlorobutyric acid buffer tank 1 through the feed pipe 9, which is fixedly connected to the top of the crude chlorobutyric acid buffer tank 1. The crude chlorobutyric acid buffer tank 1 can temporarily store the material, effectively buffering fluctuations during the material transportation process and providing stable feeding conditions for subsequent processes. At the same time, the radar level gauge 10 installed on the top of the crude chlorobutyric acid buffer tank 1 can monitor the liquid level in the tank in real time. Operators can accurately control the feed rate and subsequent transportation rhythm based on the liquid level data to ensure stable system operation. In addition, nitrogen is introduced into the top of the crude chlorobutyric acid buffer tank 1 through a pipeline to form an inert protective atmosphere, which not only prevents the material from oxidizing and deteriorating due to contact with air, but also maintains a certain pressure inside the tank, helping the material to be smoothly transported to the next stage. Next, the material is pretreated and filtered; the material at the bottom of the coarse neoprene buffer tank 1 flows into the acid water filter 6 through the pipeline, and then is pressurized and transported to the post-pump filter 8 for pretreatment under the power drive of the acid water filter pump 7. The post-pump filter 8 consists of a lower housing 11, an upper housing 12, a retaining plate 13, a filter plate 14, and a limiting assembly. The upper housing 12 is fixedly installed above the lower housing 11 by the limiting assembly. The first limiting block 15 of the limiting assembly is symmetrically fixed to the outer walls on both sides of the lower housing 11. The second limiting block 18 is supported by spring pieces 17 inside the limiting boxes 16 on both sides of the outer walls of the upper housing 12. The first limiting block 15 and the second limiting block 18 cooperate to fix the upper and lower housings 11. If the filter plate 14 needs to be replaced... The lever 20, which is fixedly connected to the slider 19 inside the limiting box 16, can be moved to make the slider 19 squeeze the spring 17, causing the second limiting block 18 to disengage from the first limiting block 15. This allows the upper housing 12 to be opened, and the filter plate 14, which is symmetrically fixed to the inner wall of the lower housing 11, can be removed and replaced. This structural design ensures that the filter plate 14 is installed stably and is easy to disassemble and maintain. It can efficiently intercept solid impurities in the material, providing clean material for the subsequent membrane separation process and avoiding impurities from contaminating the coalescence membrane and affecting the separation effect. Then, the core membrane separation operation: the clean material pretreated by the post-pump filter 8 enters the acid water separator 2. The acid water separator 2 adopts coalescing membrane separation technology, which utilizes the selective permeability of the coalescing membrane to crude chlorobutyric acid and acid water to achieve efficient separation of the two. At the same time, nitrogen gas is introduced into the top of the acid water separator 2 through a pipeline. On the one hand, it maintains the pressure inside the filter and provides a suitable pressure environment for membrane separation to improve separation efficiency. On the other hand, the inert atmosphere of nitrogen gas further protects the material from oxidation. Finally, the separated products are diverted. After separation by the coalescing membrane, the acid water separated by the acid water separator 2 is diverted through two paths: one part of the acid water enters the acid water storage tank 3 through the pipe at the bottom of the filter, and then the acid water in the acid water storage tank 3 is discharged into the acid water collection tank 5 through the bottom pipe for centralized treatment or discharge; the other part of the acid water enters the acid removal tower feed tank 4 from one side pipe at the bottom of the acid water separator 2, and enters the next process (acid removal tower) as raw material for further treatment; while the separated crude chlorobutyric acid is discharged from the corresponding outlet of the acid water separator 2, completing the entire separation process of crude chlorobutyric acid and acid water.
