Description

Technical Field

[0001] This utility model relates to the field of waste acid purification technology, and in particular to a multi-component waste acid purification device. Background Technology

[0002] Waste acid purification refers to the process of removing impurities and harmful substances from waste acid and concentrating it through a series of chemical and physical treatment steps. Waste acid purification can prevent the direct discharge of waste acid from polluting the environment, which is beneficial to environmental protection. At the same time, it can save resources. By recycling the purified resources, the amount of raw materials purchased is reduced, the cost of buying acid is lowered, and the overall economic benefits are improved. Waste acid purification equipment is required in the process of waste acid purification.

[0003] Existing waste acid purification devices can only extract certain acid products from waste acid, and the purification accuracy and efficiency are low. They cannot fully remove organic matter and solid impurities from waste acid, which is not conducive to providing high-quality raw materials for subsequent distillation purification, nor to improving distillation efficiency and product purity. At the same time, they cannot be integrated with an automatic control system to achieve real-time monitoring and precise control of the distillation process, cannot ensure efficient separation of different components, and cannot achieve graded collection of components with different boiling points, which is not conducive to improving resource utilization. They cannot ensure that exhaust gas emissions meet environmental protection requirements through a combination of absorption and adsorption. Furthermore, the devices cannot adopt a modular design, which is inconvenient for installation, maintenance, and expansion, and cannot adapt to the waste acid treatment needs of different scales.

[0026] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0027] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a multi-component waste acid purification device.

[0028] The specific technical solution includes an inlet pipe 1 and an adsorption filtration assembly 2;

[0029] like Figure 1-2 As shown, the adsorption filter assembly 2 is installed above the inlet pipe 1. The adsorption filter assembly 2 is used to remove impurities and particles from waste acid. The adsorption filter assembly 2 includes a waste acid storage tank 201 installed above the inlet pipe 1. The waste acid storage tank 201 can conveniently store waste acid. The waste acid storage tank 201 is equipped with an adsorption box 202 and a filter box 203. The adsorption box 202 is filled with an adsorbent. The adsorbent filled in the adsorption box 202 is a high-performance adsorbent that can adsorb organic matter and some inorganic impurities in the waste acid. The adsorption box 202 is located above the filter box 203. The filter box 203 can filter solid particles in the waste acid.

[0030] Waste acid is injected into the waste acid storage tank 201 from above. The waste acid then enters the adsorption box 202. The high-performance adsorbent inside the adsorption box 202 can adsorb organic matter and some inorganic impurities in the waste acid. The adsorbed waste acid enters the filter box 203, which can filter solid particles in the waste acid. The filtered waste acid can then enter the inlet pipe 1 for further processing.

[0031] like Figure 1-3As shown, a multi-component distillation assembly 3 is installed on one side of the inlet pipe 1. The multi-component distillation assembly 3 is used to separate the components of waste acid. The multi-component distillation assembly 3 includes a distillation tank 301, which can conveniently hold the steam and distilled liquid generated by heating the waste acid. The interior of the distillation tank 301 is equipped with multiple vertically arranged shelves 302, which can retain the steam generated by heating the waste acid. A pump body 303 is fixedly installed on the distillation tank 301 below the lowest shelf 302. The pump body 303 can drive the distilled liquid inside the distillation tank 301 to circulate. A pump body 303 is fixedly installed on the pump body 303, with its top penetrating the distillation tank 301. The upper part of the distillation tank 301 has a second inlet pipe 304, which allows liquid from the lower part of the distillation tank 301 to enter the upper part of the distillation tank 301. A nozzle 305 is fixedly installed above the second inlet pipe 304, located inside the distillation tank 301 and above the top shelf 302. The nozzle 305 can spray the liquid flowing out of the second inlet pipe 304. Inside the distillation tank 301, a temperature sensor 306 and a component detector 307 are fixedly installed above the top shelf 302. The temperature sensor 306 can monitor the temperature inside the distillation tank 301, and the component detector 307 can monitor the components in the waste acid vapor.

[0032] When the waste acid is heated, it generates steam. The steam enters the area below the shelves 302 inside the distillation tank 301. The temperature sensor 306 and the component detector 307 can monitor the temperature and composition of the steam, facilitating the collection of different components. The steam rises towards the shelves 302. After passing through each shelf 302, the steam is driven by the pump body 303 to draw the distilled liquid from the bottom of the distillation tank 301 into the inlet pipe 304. The distilled liquid inside the inlet pipe 304 enters the nozzle 305. The distilled liquid inside the nozzle 305 is sprayed onto the shelves 302. The steam and distilled liquid mix and fall. The mixed liquid flows downward from each shelf 302 into the bottom of the distillation tank 301. By heating the inside of the distillation tank 301, the mixed liquid generates steam that rises. The components inside the waste acid rise with the steam, pass through each shelf 302, and then enter the condenser 401.

[0033] like Figure 1-2 and Figure 4As shown, an acid collection assembly 4 is installed on one side of the distillation tank 301. The acid collection assembly 4 is used to collect high-purity acid products. The acid collection assembly 4 includes a condenser 401 fixedly installed above the distillation tank 301 and a collection tank 402 located on one side of the distillation tank 301. The condenser 401 can cool the vapor, and the collection tank 402 can easily support the turntable 403. The collection tank 402 is fixedly installed below the condenser 401 and the turntable 403 is installed on its inner bottom surface. The turntable 403 can support the inner cylinder 404. Multiple annularly arranged inner cylinders 404 are fixedly installed on the turntable 403. The inner cylinders 404 can classify and collect various high-purity acid products. Each inner cylinder 404 is located inside the collection tank 402. A motor 405 is fixedly connected to the collection tank 402 below the turntable 403. The motor 405 can drive the turntable 403 to rotate.

[0034] When the temperature sensor 306 and the component detector 307 detect the temperature of the steam and the composition of the acid products inside, they can transmit the information to the control panel. The control panel can then start the motor 405, which drives the turntable 403 to rotate inside the collection tank 402. The turntable 403 drives the inner cylinder 404 to rotate, which rotates the inner cylinder 404 used to hold the corresponding acid products to the area below the condenser tube 401. After the steam enters the condenser tube 401, it is cooled into a high-purity acid product liquid. The high-purity acid product liquid flows into a corresponding inner cylinder 404 below the condenser tube 401 and can be collected. Each inner cylinder 404 can classify and collect various high-purity acid products.

[0035] like Figure 1-2 As shown, a preheating evaporation assembly 5 is installed on one side of the inlet pipe 1. The preheating evaporation assembly 5 is used to preheat and evaporate the waste acid. The preheating evaporation assembly 5 includes a pump body 501 fixedly connected to the inlet pipe 1 and a steam pipe 502 passing through the side wall of the distillation tank 301 and located below the lowest shelf 302. The pump body 501 can drive the waste acid inside the inlet pipe 1 into the preheater 503, and the steam pipe 502 can connect to the evaporator 5. 05 and distillation storage tank 301, pump body 2 501 are equipped with a preheater 503 on the side wall. The preheater 503 can preheat the waste acid. A liquid inlet pipe 3 504 is installed on one side of the preheater 503. The liquid inlet pipe 3 504 can drive the preheater 503 to connect with the evaporator 505. The evaporator 505 is installed between the steam pipe 502 and the liquid inlet pipe 3 504. The evaporator 505 achieves the preliminary separation of low boiling point components in the waste acid by controlling the temperature and pressure inside.

[0036] By activating pump body 2 501, the waste acid inside inlet pipe 1 is driven into preheater 503. The preheater 503 heats the waste acid, and the preheated waste acid, under the pressure of pump body 2 501, can enter inlet pipe 3 504. The waste acid inside inlet pipe 3 504 can enter evaporator 505, where the waste acid can be heated to generate steam. The acid products inside the waste acid can enter the distillation storage tank 301 through steam pipe 502 along with the steam.

[0037] like Figure 1-2 As shown, the top and one side of the distillation tank 301 are respectively equipped with a tail gas pipe 6 and an absorption tower 7. The tail gas pipe 6 allows the tail gas to enter the absorption tower 7, and the absorption tower 7 can absorb the tail gas. The tail gas pipe 6 passes through the side wall of the absorption tower 7. A purification box 8 located above the tail gas pipe 6 is fixedly installed inside the absorption tower 7. The purification box 8 can easily adsorb harmful substances in the tail gas.

[0038] The exhaust gas enters the absorption tower 7 through the exhaust pipe 6 and is absorbed. The exhaust gas inside the absorption tower 7 rises into the purification box 8. The purification material inside the purification box 8 can re-adsorb the harmful substances in the exhaust gas. Only after the exhaust gas is purified can it be discharged, which is beneficial to environmental protection.
