Description

Technical Field

[0001] This utility model relates to the field of acid solution treatment technology, and in particular to a room temperature condensation and evaporation reactor for acid solution treatment. Background Technology

[0002] Acidic solutions are solutions in which the concentration of hydrogen ions is greater than that of hydroxide ions, and the pH value is less than 7. Ambient temperature condensation-evaporation reactors for acidic solution treatment are chemical equipment used to treat acidic solutions. They combine evaporation and condensation technologies and can separate, concentrate, or recover solutes in acidic solutions under ambient temperature conditions. They can also treat volatile acidic gases and can be used to treat acidic wastewater, recover valuable solutes such as sulfuric acid and hydrochloric acid, or concentrate acidic solutions.

[0003] Currently, ambient temperature condensation and evaporation reactors for acidic solution treatment can basically meet people's needs. However, the temperature of conventional concentrated and dilute acid recovery reactors is too high, which leads to excessive acid evaporation and can easily damage temperature-sensitive useful substances in the original solution. Utility Model Content

[0004] The purpose of this invention is to provide a room temperature condensation-evaporation reactor for acidic solution treatment, in order to solve the problem that existing room temperature condensation-evaporation reactors for acidic solution treatment are difficult to control the reactor temperature.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a room temperature condensation and evaporation reactor for acidic solution treatment, including a support frame;

[0006] A condensation chamber is installed at the top of the support, a control box is installed at the bottom of the support, and a crystallization reaction chamber is installed on one side of the support.

[0007] Both sides of the bottom of the crystallization reaction chamber are equipped with support legs, a heater is installed at the bottom of the crystallization reaction chamber, an evaporator is installed at the top of the crystallization reaction chamber, and a vacuum pump is installed on one side of the top of the crystallization reaction chamber.

[0008] The condensation chamber is equipped with a cooling mechanism, which includes a connecting pipe installed inside the condensation chamber, a cooling pipe installed at the top of the connecting pipe, and a water inlet pipe installed on one side of the top of the cooling pipe.

[0009] In use, the solution is first cooled inside the condensation chamber, and then enters the crystallization reaction chamber for reaction. The reacted solution can be discharged through the outlet. The ambient temperature condensation evaporation reactor effectively solves these problems in recovering volatile acids. The system operates under a certain vacuum, resulting in a lower evaporation temperature, essentially solving the problem of acid volatilization at room temperature and effectively addressing the issue of acid volatilization under high-temperature environments. Recovery efficiency is greatly improved, and because it operates at room temperature, the activity of the raw materials is better preserved.

[0010] Furthermore, a stirring mechanism is installed inside the crystallization reaction chamber, and the stirring mechanism includes a servo motor installed on one side of the crystallization reaction chamber, a stirring shaft installed on one side of the servo motor, and stirring blades installed on the outer side of the stirring shaft. The stirring blades can stir the interior of the crystallization reaction chamber.

[0011] Furthermore, a scraper is provided on the outer side of the stirring blade. The scraper is symmetrically distributed about the central axis of the stirring shaft. The scraper can scrape the inner wall of the crystallization reaction chamber.

[0012] Furthermore, a discharge mechanism is installed at the bottom of one side of the crystallization reaction chamber. The discharge mechanism includes a first flange installed at the bottom of one side of the crystallization reaction chamber, and a second flange installed on one side of the first flange. A fixing screw is installed on one side of the first flange, and a nut is installed on one side of the fixing screw. A pump body is installed on one side of the second flange, and a discharge port is installed at the bottom of the pump body. The device can discharge materials through the discharge mechanism.

[0013] Furthermore, the outer side wall of the fixing screw is uniformly provided with external threads, and the inner side wall of the nut is uniformly provided with internal threads that cooperate with the external threads. The fixing screw and the nut are threadedly connected, and the first flange and the second flange can be fixed by the fixing screw.

[0014] Furthermore, a locking block is provided on one side of the first flange, and a locking groove is provided on one side of the second flange. The first flange and the second flange form a locking structure, which facilitates disassembly.

[0015] Furthermore, the nuts are arranged in a ring shape and at equal intervals on one side of the second flange. The nuts and fixing screws work together to fix the first flange and the second flange.

[0016] The advantages of the ambient temperature condensation and evaporation reactor for acid solution treatment provided by this utility model are: the reactor temperature can be adjusted and cooled by a cooling mechanism; the crystallization reaction chamber can be stirred by a stirring mechanism to improve the processing reaction effect; and the material can be discharged by a discharge mechanism.

[0017] By installing cooling pipes inside the condensation chamber, the ambient temperature condensation evaporation reactor effectively solves these problems in recovering volatile acids. The ambient temperature condensation evaporation reactor processes volatile acids, and the system operates under a certain vacuum, resulting in a lower evaporation temperature, which basically solves the problem of acid volatilization under high temperature conditions. The recovery efficiency is greatly improved. Because it is at ambient temperature, the activity of the raw materials can be better maintained, thereby achieving the purpose of easy temperature control of the reactor for acid solution treatment.

[0018] By installing a servo motor on one side of the crystallization reaction chamber, the servo motor drives the stirring shaft to rotate, which in turn drives the stirring blades to rotate. The rotation of the stirring blades stirs the inside of the crystallization reaction chamber, improving the reaction effect. The rotation of the stirring blades also drives the scraper to rotate, which scrapes the inner wall of the crystallization reaction chamber to prevent crystals from adhering to the inner wall. This achieves the goal of improving the processing efficiency of the crystallization reaction chamber in an ambient temperature condensation evaporation reactor for acidic solution treatment.

The rotation of the stirring blade 803 stirs the inside of the crystallization reaction chamber 4, making the reaction inside the crystallization reaction chamber 4 more effective. The rotation of the stirring blade 803 also drives the scraper 804 to rotate, which scrapes the inner wall of the crystallization reaction chamber 4 to prevent crystals from adhering to the inner wall of the crystallization reaction chamber 4.

[0030] A second flange 702 is installed on one side of the first flange 701, and a fixing screw 703 is installed on one side of the first flange 701.

The solution after reaction can be discharged through the outlet 706. The pump body 705 will suck out the solution after processing, and then discharge the solution through the outlet 706.

The ambient temperature condensation evaporation reactor effectively solves these problems by recovering these volatile acids. The ambient temperature condensation evaporation reactor processes volatile acids. Under a certain vacuum degree, the vacuum pump 10 can evacuate the crystallization reaction chamber 4. The evaporation temperature is low, which basically solves the problem of acid volatilization under ambient temperature. The problem of acid volatilization under high temperature environment is effectively solved, and the recovery efficiency is greatly improved. Since it is at ambient temperature, the activity of the materials in the raw materials can be better maintained.
