Description

Technical Field

[0001] The invention relates to the technical field of ammonia water separation and purification, in particular to an ammonia water pretreatment purification and separation device. Background Art

[0002] Ammonia water, also known as ammonia water, can be used as agricultural fertilizer, catalyst for chemical reactions, dyeing aid and pH adjustment reagent in the textile industry, and alkalizing reagent in pharmaceutical operations. Traditional ammonia water preparation generally involves mixing ammonia gas and water, the main raw materials of ammonia water, and removing impurities such as precipitates and fixed particles generated during the mixing process to purify the ammonia water.

[0003] The existing Chinese patent application with publication number CN116870536A discloses a tar-ammonia-water separator, comprising a box body, a liquid inlet pipe is connected to the top of the box body, a partition is arranged in the middle of the box body, a first sedimentation chamber is arranged on one side of the partition, and a second sedimentation chamber is arranged on the other side of the partition, stirring mechanisms are installed at the centers of the first sedimentation chamber and the second sedimentation chamber, and liquid outlets are opened at the bottoms of the first sedimentation chamber and the second sedimentation chamber; the invention, by arranging the stirring mechanism, can increase the pre-stirring centrifugal function of the separator, accelerate the stratification speed of ammonia water, tar and tar residue, and shorten the time required for the tar-ammonia-water mixture to stand and stratify; by arranging the first sedimentation chamber and the second sedimentation chamber, the separation processes in the first sedimentation chamber and the second sedimentation chamber can be staggered, which changes the situation in which the separation of the traditional separator is interrupted when the tar-ammonia-water mixture is standing, can greatly shorten the time required for a single separation of the tar-ammonia-water mixture, and accelerate the work efficiency of the separation of the tar-ammonia-water mixture.

[0004] However, the ammonia water separation and purification device has the following defects when used specifically: 1. When the existing ammonia water separation and purification device separates the precipitate and particles and other impurities in the ammonia water to obtain ammonia water with higher purity, the generation of precipitate is generally accelerated by stirring. However, when the ammonia water is purified by stirring, the rotation of the stirring mechanism is generally only in a single direction. When a large amount of ammonia water is prepared and processed at one time, the preparation and processing effects are poor. At the same time, the precipitate and other particulate impurities in the ammonia water are easy to adhere to the inner wall of the ammonia water device during the stirring process, which is easy to cause secondary contamination of the ammonia water when the next group of ammonia water is prepared, affecting the effect of ammonia water purification; 2. When the existing ammonia water separation and purification device stirs the ammonia water to obtain the precipitate and separates it, the dissolution efficiency of ammonia gas is low during the generation of ammonia water, and the efficiency of preparing ammonia water is low. At the same time, during the discharge process, ammonia gas will move upward inside the container. At this time, part of the ammonia gas will accumulate on the inner top of the container and will not come into contact with water, resulting in easy waste when preparing ammonia water.

At the same time, when the main shaft rotates, it will drive the concave frame and eccentric rod installed at the bottom to rotate, stir the water and ammonia set at the bottom of the purification and separation tank, and improve the effect of preparing (stirring and mixing) ammonia and water. While the concave frame rotates, it will synchronously drive the first rotating shaft, the transmission belt, the second rotating shaft, the third gear, the fourth gear, the movable disk, the eccentric protrusion and the connecting rod connected to the bottom to operate, and drive the middle stirring roller connected to the movable disk to rotate (opposite to the rotation direction of the concave frame), so as to ensure that when the ammonia and water at the bottom of the purification and separation tank are stirred and prepared, two sets of eddies with opposite rotation directions inside and outside can be generated, so as to maximize the contact area between ammonia and water when mixing. Furthermore, the precipitate or particulate impurities generated when ammonia gas and water are mixed can be moved in a spiral rotation in forward and reverse directions, ensuring that the precipitate or particulate impurities can adhere to each other and adsorb together during the generation and movement process, thereby expanding the volume of the precipitate or particulate impurities and avoiding the problem of being discharged from the mesh of the separation screen when the prepared ammonia water is discharged; 2.

At the same time, it can avoid the problem of secondary contamination of ammonia by sediment and particulate impurities adhering to the inner wall of the purification and separation tank when preparing ammonia for multiple times continuously. In addition, the inner wall of the sweeping plate is connected to the outer side of the side connecting rod through the oblique rod and the center recess, forming a triangle with the side connecting rod, the oblique rod and the sweeping plate, thereby ensuring the stability of the sweeping plate during continuous rotation and the effect of sweeping and cleaning the inner wall of the purification and separation tank; 3. In the ammonia pretreatment purification and separation device, the ammonia gas transmitted to the purification and separation tank during the preparation of ammonia water can be preheated by the heating module and the power module to ensure the efficiency of ammonia gas during preparation. At the same time, in the process of preparing water and ammonia gas (stirring and mixing), multiple sets of electromagnetic heaters and heating metal heads can heat multiple parts inside the purification and separation tank to ensure the ability of ammonia gas to dissolve and diffuse in water. In addition, the exhaust pipe for discharging ammonia gas is arranged below the middle of the purification and separation tank.
