DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0022] First Embodiment

[0023] Please refer to Figure 1 wherein Figure 1 is a schematic structural diagram of the first embodiment of a waste liquid incineration alkali ash and alkali residue purification system provided by the present utility model. A waste liquid incineration alkali ash and alkali residue purification system includes: a dissolution kettle 3, two filters 31 are provided at the output end of the dissolution kettle 3, a crystallizer 32 is provided at the output ends of the two filters 31, a centrifuge 33 is provided at the output end of the crystallizer 32, a circulating mother liquor tank 34 and a drying bed 35 are respectively provided at the output end of the centrifuge 33, a scraper conveyor 36 and a cyclone separator 39 are respectively provided at the output end of the drying bed 35, a bucket elevator 37 is provided at the output end of the scraper conveyor 39, a dissolution tank 38 is provided at the output end of the cyclone separator 39, and an induced draft fan 30 is fixedly installed at the air outlet end of the cyclone separator 39.

[0024] A pump body is fixedly installed at the output end of the circulating mother liquor tank 34 and is connected to the dissolution kettle 3 through the pump body.

[0025] The output end of the dissolution tank 38 is connected to the dissolution kettle 3.

[0026] When the drying bed 35 is in use, a blower blows air on the heating wire to dry the sodium sulfate crystals;

[0027] The inside of the cyclone separator 39 is evacuated by the induced draft fan 30, so that dust and gas can be separated, and then the dust enters the inside of the dissolution tank 38 and the gas is discharged.

[0028] The working principle of a waste liquid incineration alkali ash and alkali residue purification system provided by the present utility model is as follows:

[0029] During use, soda ash and soda residue are put into the interior of the dissolving kettle 3, and then process water is added for a dissolving reaction. After that, the solution is transported through a pump and pipeline into the interior of two filters 31 for filtration. After the filtration is completed, it is transported through a pipeline into the interior of the crystallizer 31 for crystallization. After the crystallization is completed, it is transported into the interior of the centrifuge 33. The sodium sulfate crystals and the liquid are separated by the centrifuge 33. Then, the sodium sulfate crystals are transported onto the drying bed 35 for drying. After the sodium sulfate crystals are dried, they are transported by a scraper conveyor to a bucket elevator 37 for feeding onto a transport vehicle. At the same time, the liquid separated by the centrifuge 33 will enter the interior of the circulating mother liquor tank 34, and then is transported again through a pump into the interior of the dissolving kettle 3 for reuse. The sodium sulfate crystal dust generated during the drying of the drying bed 35 will be separated by a cyclone separator 39, transported into the interior of the dissolving tank 38 for dissolution, and then transported into the dissolving kettle 3 through a pump for reuse.

[0030] Compared with the related art, a waste liquid incineration soda ash and soda residue purification system provided by the present utility model has the following beneficial effects:

[0031] Through the cooperation of structures such as the dissolving kettle 3, the filter 31, the crystallizer 32, the centrifuge 33, and the drying bed 35, during use, directly scrapping the soda ash and soda residue is avoided, and the sodium sulfate in the soda ash and soda residue can be purified and reused, thereby reducing production costs and avoiding waste of resources.

[0032] Second Embodiment

[0033] Please refer to Figure 2 、 Figure 3 Based on a waste liquid incineration soda ash and soda residue purification system provided in the first embodiment of the present application, a second waste liquid incineration soda ash and soda residue purification system is proposed in the second embodiment of the present application. The second embodiment is merely a preferred manner of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0034] Specifically, the difference of a waste liquid incineration soda ash and soda residue purification system provided in the second embodiment of the present application is that, for a waste liquid incineration soda ash and soda residue purification system, the crystallizer 32 includes a body 1, a driving motor 2, a rotating shaft 21, a connecting rod 23, and a scraper 24. The driving motor 2 is fixedly installed on the top of the body 1. The rotating shaft 21 is fixedly installed at the output end of the driving motor 2 and is disposed on the inner side surface of the body 1. The connecting rod 23 is fixedly installed at the tops on both sides of the rotating shaft 21. The scraper 24 is fixedly installed at one end of the connecting rod 23, and one side of the scraper 24 abuts against the inner wall of the body 1.

[0035] The outer side surface of the rotating shaft 21 is fixedly installed with a stirring blade 22, and the other side of the scraping plate 24 is fixedly installed with a stirring rod 25.

[0036] The four sides of the bottom of the body 1 are fixedly installed with support feet 12.

[0037] The front surface of the body 1 is fixedly installed with an observation window 11.

[0038] The body 1 is a crystallization tank, which is used to cool and crystallize the material during use.

[0039] The working principle of a waste liquid incineration alkali ash and alkali residue purification system provided by the present invention is as follows:

[0040] During use, the material is conveyed into the interior of the body 1, and the body 1 crystallizes the material. At this time, the user can start the driving motor 2, so that the driving motor 2 drives the rotating shaft 21 to rotate, thereby enabling the rotating shaft 21 to drive the stirring blade 22 to stir the material, thereby enhancing the crystallization effect. When the crystallization is completed and the crystallized material adheres to the inner wall of the body 1, the user can start the driving motor 2 again, so that the driving motor 2 drives the rotating shaft 21 to rotate, thereby enabling the rotating shaft 21 to drive the connecting rod 23 to rotate, and then enabling the connecting rod 23 to drive the scraping plate 24 to rotate on the inner side surface of the body 1, thereby scraping the crystallized material on the body 1 to avoid adhesion, and then discharging it through the discharge port provided at the bottom of the body 1.

[0041] Compared with the related art, a waste liquid incineration alkali ash and alkali residue purification system provided by the present invention has the following beneficial effects:

[0042] Through the cooperation of structures such as the driving motor 2, the rotating shaft 21, the stirring blade 22, the connecting rod 23, the scraping plate 24 and the stirring blade 25, after the crystallization is completed, the rotation of the driving motor 2 drives the scraping plate 24 to rotate, thereby being able to clean the material adhering to the inside of the body 1, and avoiding the adhesion and accumulation of the material from affecting the normal crystallization of the subsequent material.

[0043] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
