[0043] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Although exemplary embodiments are disclosed in the accompanying drawings, it should be understood that the utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to facilitate a thorough understanding of the utility model and to fully convey the concept of the utility model to those skilled in the art.

[0044] See also Figures 1 to 5 As shown, an embodiment of the utility model provides a water washing desalination device with a collection function, including a filtering system 2, a pretreatment system 1, a water washing reactor 5, a heating evaporation system 9 and a condenser 8 connected in sequence.

[0045] Specifically, the filtration system 2 is arranged on the pretreatment system 1 and is connected to the pretreatment system 1; it is mainly used to remove solid particles and impurities in the fly ash, thereby improving the subsequent treatment efficiency; distilled water and fly ash are added to the pretreatment system at a weight ratio of 2:1 for water-ash, and the filtered fly ash is first transported to the inside of the pretreatment system 1, and at the same time, distilled water is added from the distilled water inlet of the pretreatment system to the inside of the pretreatment system 1 through a distilled water adding device (not annotated in the figure), and the pretreatment system 1 is started, and the sodium salt and hardness index in the water are removed through the pretreatment system 1. The pretreatment system 1 is preferably an electrode physical desalination equipment with full automatic control of PLC.

[0046] Furthermore, the drain outlet of the pretreatment system 1 is connected to the conveying pipe 3, and is connected to the water washing reactor 5 through the conveying pipe 3. The salt in the water washing reactor is dissolved into water, thereby achieving further desalination of the fly ash. The water washing reactor is preferably a volumetric water washing reactor.

[0047] Furthermore, the water washing reactor 5 is connected to the heating evaporation system 9 through a pipe group. The heating evaporation system 9 includes a gas-liquid separator 4 connected thereto. The gas-liquid separator 4 includes a liquid delivery pipeline 10 and a gas delivery pipeline 12, and is connected to the condenser 8 through the gas delivery pipeline 12. The condenser 8 is preferably a WLSJ series condenser; the liquid delivery pipeline 10 is connected to the collector 7.

[0048] In the present embodiment, first, the fly ash-water mixed liquid flows into the heating evaporation system 9. The heating evaporation system is a prior art and is not described in detail in the present embodiment. The heating evaporation system 9 is started, and heating is performed inside the heating evaporation system 9 to perform high-temperature evaporation to obtain evaporated steam. The high-temperature steam enters the gas-liquid separator 4, enters the gas delivery pipeline 12 through the steam outlet of the gas-liquid separator, and is transported to the condenser 8 through the gas delivery pipeline 12.

[0049] See also Figures 1 to 5As shown, those skilled in the art should be able to understand that in order to solve the problem that the steam after being treated by the heating evaporation system still contains a certain amount of sodium salt and cannot be completely removed, if it directly enters the condensation system, the sodium salt will form scaling on the inner wall of the condensation system, thereby greatly increasing the energy consumption, the gas delivery pipeline 12 in the utility model is higher than the liquid delivery pipeline, and the height ratio is 6:1; and the gas delivery pipeline is preferably made of a high-temperature and corrosion-resistant nickel-based alloy; when used, since the density and weight of steam containing sodium salt are much greater than steam not containing sodium salt, a large part of the high-temperature steam containing sodium salt can be filtered out and enter the condenser by selecting a gas delivery pipeline 12 that is six times larger than the liquid delivery pipeline.

[0050] Since the liquid delivery pipeline 10 is connected to the collector 7, the high-temperature steam containing sodium salt stays inside the gas delivery pipeline 12. After a period of static time, the temperature drops, condenses into water droplets and flows back to the gas-liquid separator 4, and is transported to the collector 7 through the liquid delivery pipeline 10 of the gas-liquid separator for collection.

[0051] See also Figures 2 to 5 As shown, the collector 7 is provided with a drain pipe 71, on which a control valve 72 is provided, and the outflow of liquid is controlled by the control valve; the drain pipe 71 is connected with the heating evaporation system 9, and a heating layer 73 is provided inside the cylinder of the collector 7, and the heating layer 73 has a built-in circulation pipeline, and the circulation pipeline is connected with the heating pipe 11, and the heating pipe 11 is connected with an external heating device, so that the heating medium flows in the heating pipe 11.

[0052] Furthermore, a removal assembly 76 is provided inside the collector 7 , and the removal assembly 76 includes a pushing member 761 and a driving assembly 762 .

[0053] A driving assembly 762 is provided at the top of the removal assembly 76, and the driving assembly 762 drives the removal assembly 76 to move linearly in the collector 7;

[0054] The driving assembly 762 includes two upper and lower groups of first driving seats 7622 and second driving seats 7625, and the first driving seat 7622 is slidably installed in the collector 7. When installing, a sliding connection method such as a slide groove can be used. Regarding the sliding installation of the first driving seat in the collector, it is a prior art and will not be described in detail here;

[0055] A positioning member 7621 is disposed in the middle of the first driving seat 7622, ​​and a groove is formed at one end of the positioning member 7621 facing the second driving seat 7625, and a magnet is adhered to the inner wall of the groove;

[0056] At least one set of first through holes 7623 is defined on the first driving seat 7622 .

[0057] Furthermore, at least one group of second through holes 7626 is formed on the second driving seat 7625. When the first driving seat 7622 and the second driving seat 7625 are assembled, the first through holes 7623 and the second through holes 7626 are arranged corresponding to each other in the upper and lower parts.

[0058] Furthermore, a clamping piece 7624 is provided on the side of the second driving seat 7625 facing the first driving seat 7622, ​​and the clamping piece 7624 is made of a magnet. The clamping piece 7624 cooperates with the magnet in the groove to attract each other (the clamping piece and the magnet in the groove are special-shaped magnets), so that the clamping piece 7624 automatically snaps into the groove for clamping and connection.

[0059] See also Figure 3 As shown, the second driving seat 7625 is fixedly connected to at least one set of cleaning rings 764 via a connecting rod 763 .

[0060] Furthermore, the push-up member 761 includes a shaft 7611, and the shaft 7611 passes through a through hole in the middle of the driving assembly 762 and extends into the collector 7;

[0061] A spiral blade 7612 is fixedly mounted on the shaft 7611 , and the other end of the shaft 7611 is fixedly mounted on the cleaning ring 764 via a connecting piece 7613 .

[0062] Those skilled in the art should be able to understand that since the liquid containing sodium salt will enter the collector 7, scaling will be formed on the inner wall of the collector, thereby corroding the collector. In order to reduce corrosion, the collector 7 needs to be descaled. The utility model can effectively remove impurities on the inner wall of the collector 7 by adding a removal component 76.

[0063] When the second driving seat 7625 at the top of the removal assembly 76 is in a separated state from the first driving seat 7622, ​​and the first through hole 7623 and the second through hole 7626 are staggered, the first driving seat and the second driving outer wall are in contact with the inner wall of the collector, so the interior of the collector is in a relatively sealed state at this time;

[0064] At this time, it is necessary to connect the heating tube 11 to the external heating equipment, so that the heating medium flows in the heating tube 11, and the heating medium is transported to the heating layer 73 in the collector 7 through the heating tube 11; so that the collector 7 starts to be heated at high temperature to generate high-temperature steam, and at this time, when the high-temperature steam flows upward in the collector, it will drive the removal component to move upward, and the removal component is driven to lift by the high-temperature steam. Due to the upward movement of steam, the removal component 76 can be pushed by the steam. Since the removal component 76 is equipped with spiral blades 7612, relative kinetic energy is generated by the upward moving high-temperature steam. When the steam flows through the spiral blades, the high-temperature steam will collide with the spiral blades, thereby generating a certain pressure, and the pressure drives the spiral blades to rotate, thereby further pushing the removal component to move upward; thereby removing the scale on the inner wall of the collector;

[0065] Until the clamping piece 7624 of the second driving seat is automatically locked into the groove, so that the first driving seat and the second driving seat are locked and connected, at this time the first through hole 7623 and the second through hole 7626 are arranged one by one up and down, the steam flows out, and the relatively sealed space is released. At this time, it falls under the action of gravity and returns to its original position, completing a scale cleaning.

[0066] The use process and working principle of the utility model are:

[0067] In order to solve the problem that the steam after being treated by the heating evaporation system still contains a certain amount of sodium salt, which cannot be completely removed. If it directly enters the condensation system, the sodium salt will form scaling on the inner wall of the condensation system, thereby greatly increasing the energy consumption, the gas delivery pipeline 12 in the utility model is higher than the liquid delivery pipeline, and the height ratio is 6:1; and the gas delivery pipeline is preferably made of a high-temperature and corrosion-resistant nickel-based alloy; when used, since the density and weight of steam containing sodium salt are much greater than steam not containing sodium salt, a large part of the high-temperature steam containing sodium salt can be filtered out and enter the condenser by selecting a gas delivery pipeline 12 that is six times larger than the liquid delivery pipeline.

[0068] Since the liquid delivery pipeline 10 is connected to the collector 7, the high-temperature steam containing sodium salt stays in the gas delivery pipeline 12. After a period of rest, the temperature drops, condenses into water droplets and flows back to the gas-liquid separator 4, and is transported to the collector 7 through the liquid delivery pipeline 10 of the gas-liquid separator for collection. When the liquid in the collector 7 fills the collector 7, the control valve 72 is started at this time to allow the liquid in the collector 7 to flow into the heating evaporation system 9 through the drain pipe 711, realizing circulation and performing desalination treatment again.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not restrictive. Although the utility model is described in detail with reference to the embodiments, it should be understood by those skilled in the art that any modification or equivalent replacement of the technical solution of the utility model does not deviate from the spirit and scope of the technical solution of the utility model, and should be included in the scope of the claims of the utility model.
