[0002] In chemical industries such as salt production, it is necessary to store the liquid to be treated in a large evaporating vessel, and then treat it in a high temperature and high pressure environment to obtain the desired substance after evaporation.

[0003] However, in the prior art, brine needs to be added during the evaporation process of salt production. As the evaporation proceeds, impurities in the brine will continue to be enriched with the evaporation. The enrichment leads to an increase in the concentration of impurities and an increase in viscosity, which is likely to cause enrichment and agglomeration inside the evaporation tank, thereby agglomerating and hanging on the tank body, that is, forming agglomerated and dense salt blocks. When there are more salt blocks in the tank body, the evaporation efficiency is reduced, and it is easy to cause industrial accidents and increase production costs, which is not conducive to the further improvement and improvement of the salt production process.

[0028] The utility model provides an automatic flushing evaporation tank in an embodiment. By improving the structure of the evaporation tank, the interior of the evaporation tank can be flushed regularly and the problem of salt blocks easily forming on the inner wall of the evaporation tank can be effectively avoided.

[0029] like Figure 1 As shown, Figure 1 The automatic flushing evaporation tank provided in the embodiment of the utility model includes a tank body 201 , a spray pipe 101 , and a control module 301 .

[0030] Specifically, the tank body 201 is mainly used to store liquid, such as the liquid stored therein is a salt solution containing a certain amount of liquid to be evaporated. When the tank body 201 is set, the tank body 201 can be set to a variety of shapes or structures, and any device that can accommodate or store liquids is within the scope of protection of the present utility model. In the following embodiments, the tank body 201 is described by taking a cylindrical tank body as an example. When the cylindrical tank body is working, a liquid inlet 302 is provided on its upper part. Liquid is poured through the liquid inlet 302 to be evaporated and extracted later. At the same time, for the cylindrical tank body, the diameter of the cylindrical tank on the side close to the liquid inlet 302 is less than or equal to the diameter of the cylindrical tank on the side away from the liquid inlet 302.

[0031] Optionally, when the tank body 201 is provided, it may further include a sealing cover. When the solution needs to be stored, the sealing cover may be opened. During the evaporation process, the sealing cover may be closed and evaporation may be performed.

[0032] Further, in the embodiment of the utility model, when the spray pipe 101 is provided, the spray pipe 101 is provided along the inner wall of the tank body 201. When providing, a plurality of spray pipes 101 can be provided on the inner wall of the tank body 201 as required.

[0033] In one embodiment of the present invention, the plurality of spray pipes 101 may be arranged at intervals, such as being arranged at equal intervals between two adjacent spray pipes 101. Figure 1 In the embodiment, the extension direction of the plurality of injection pipes 101 is arranged parallel to the axis MM of the tank body 201 , so that the plurality of injection pipes 101 are equivalent to being vertically arranged on the inner wall of the tank body 201 .

[0034] In the above arrangement, a plurality of cleaning nozzles 105 are also provided on each spray pipe 101. Figure 1 In the partially cut-away area 106, three cleaning nozzles 105 are also provided on each spray pipe 101. When the inner wall of the tank body 201 needs to be flushed, a cleaning liquid is introduced into the spray pipe 101, and at the same time, the salt blocks on the inner wall are flushed through the multiple cleaning nozzles 105.

[0035] Furthermore, in the embodiment of the utility model, the size of the cleaning nozzle 105 on each spray pipe 101 can be set according to the demand. For example, the caliber of the cleaning nozzle 105 on the side close to the top of the tank body 201 is smaller than the caliber of the cleaning nozzle 105 on the side away from the top of the tank body 201. Optionally, when the cleaning nozzle 105 is set differently, in the area of ​​the tank body where salt blocks are easily enriched, the caliber of the corresponding cleaning nozzle 105 is larger than the caliber of the cleaning nozzle 105 in other areas, so as to ensure the flushing effect in the enriched area.

[0036] Furthermore, in the second embodiment of the present invention, the arrangement or structure of the injection pipe 101 can also be changed. Figure 2 As shown, Figure 2 Another arrangement structure of the injection pipe provided in the embodiment of the utility model. Figure 1 In the embodiment of the utility model, when multiple injection pipes 101 are arranged on the inner wall of the tank body 201, they can be arranged in a ring along the inner wall of the injection pipe 101. When the tank body 201 is a cylindrical tank body, multiple circles of injection pipes 101 are arranged along the inner wall of the tank body 201 from the top to the bottom of the tank body 201.

[0037] In the embodiment of the utility model, when the spray pipe 101 is arranged in multiple circles or rows, multiple cleaning nozzles 105 are arranged on each circle of the spray pipe 101. When the spray pipe 101 is arranged, its length can be set according to actual needs, such as each spray pipe 101 is arranged as a complete circle, or is arranged as a half circle along the inner wall, or other lengths.

[0038] Furthermore, the spacing between two adjacent injection pipes 101 near the top of the tank body is greater than the spacing between two adjacent injection pipes 101 away from the top of the tank body. In the actual production process, the bottom area of ​​the tank body is more prone to enrichment problems. Therefore, the spacing between two adjacent injection pipes 101 at the bottom is smaller, so that more cleaning nozzles 105 can be set to improve the flushing effect and avoid the problem of salt blocks in this area.

[0039] At the same time, the number of cleaning nozzles 105 on the spray pipe 101 away from the top side of the tank body 201 is greater than or equal to the number of cleaning nozzles 105 close to the top side of the tank body 201. In this way, the flushing effect is improved by increasing the number of cleaning nozzles 105.

[0040] Further, in the embodiment of the utility model, Figure 1 as well as Figure 2 In the arrangement mode, the injection pipe 101 may include a first injection pipe 1011 and a second injection pipe 1012. The first injection pipe 1011 is arranged on one side of the second injection pipe 1012.

[0041] In the embodiment of the present invention, the diameter of the first spray pipe 1011 is greater than or equal to the diameter of the second spray pipe 1012. Figure 2 In the embodiment, the diameter of the second spray pipe 1012 is smaller than the diameter of the first spray pipe 1011. In this way, the first spray pipe 1011 is arranged near the bottom area, and the caliber of the cleaning nozzle 105 on the corresponding first spray pipe 1011 can be larger than the caliber of the cleaning nozzle 105 on the second spray pipe 1012. Thus, the cleaning effect of the cleaning nozzle 105 in the bottom area is improved.

[0042] Furthermore, the first injection pipe 1011 and the second injection pipe 1012 can be arranged alternately in sequence. Alternatively, according to the requirements, the first injection pipe 1011 with a larger diameter can be arranged in the area inside the tank where salt blocks are easily accumulated.

[0043] See Figure 1 In the embodiment of the utility model, the automatic flushing evaporator further comprises a control main pipe 104 , which is connected to the plurality of injection pipes 101 through the control main pipe 104 , and when the flushing liquid enters, it is transmitted from the control main pipe 104 to other injection pipes 101 respectively.

[0044] Meanwhile, the control module 301 also includes instruments such as a flow meter 102, an electric valve 103, and a pressure gauge. Specifically, the control module 301 can be connected to the control main pipe 104. When the evaporator is working, the control module 301 can control the flushing liquid in the control main pipe 104 to enter each injection pipe 101. When the electric valve 103 in the control module 301 is opened, the flushing liquid can enter from the control main pipe 104 to achieve the purpose of flushing.

[0045] In the embodiment of the utility model, the control module 301 can be adjusted, such as setting the opening time of the electric valve 103 , so that the electric valve 103 automatically opens within the set time, thereby flushing the inner wall of the tank body 201 through the cleaning nozzle 105 .

[0046] In the embodiment of the utility model, when the spray pipe 101 is provided, the diameter of the spray pipe can be set according to the demand, and is not limited here. At the same time, the flushing range of each cleaning nozzle 105 is set to 1.3m to 1.7m.

[0047] In order to improve the flushing effect of the automatic flushing evaporator, in the present invention, the instantaneous flow rate of flushing water of the cleaning nozzle 105 is 1.0m 3 / min~1.5m 3 / min, and the injection water pressure in the injection pipe 101 is greater than the flash space pressure in the tank body 201, such as 0.3MPa~0.5MPa greater than the flash space pressure in the tank body 201. Optionally, the steam flow rate in the flash space in the evaporator is called "superficial velocity", which is generally 5m / s. In order to ensure a better cleaning effect, the flow rate of the flushing water is controlled to be 2~3 times the superficial velocity in the tank, such as the flushing flow rate is 10m / s~15m / s.

[0048] In the embodiment of the utility model, an automatic flushing evaporation tank is provided. Through regular flushing, the salt blocks formed on the inner wall of the evaporation tank are promptly broken and flushed down, and the salt blocks are washed away when they are no longer agglomerated. After the device is put into use and trial production is carried out for half a year to one year, the discharge inspection shows that there are no salt blocks agglomerated on the inner wall of the evaporation tank. In addition, by controlling the flow rate of the sprayed water in the utility model, the negative impact of flash steam carrying liquid can be effectively avoided.

[0049] The above description is only a partial implementation method of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the technical concept of the present invention, other similar implementation methods based on the technical ideas of the present invention are also within the protection scope of the embodiments of the present invention.
