Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment devices, in particular to a desulfurization liquid evaporation device. Background Art

[0002] Desulfurization waste liquid contains a large amount of water, which can be vaporized and removed through an evaporation device. For example, in common desulfurization waste liquid, the water content may be as high as 90% or more. The evaporation process can make the water in the waste liquid escape in the form of water vapor, thereby greatly reducing the volume of the waste liquid. Generally, after evaporation treatment, the volume of the waste liquid can be reduced to a fraction of the original or even less.

[0003] The reduction in volume reduces the subsequent transportation, storage and treatment costs. If a large amount of desulfurization waste liquid is treated directly, whether it is chemical precipitation, biological treatment or other deep treatment technologies, large-scale liquid treatment requires huge reaction vessels and more chemical agents. After evaporation and concentration, the amount of waste liquid that needs to be treated is reduced, and the corresponding treatment facility scale, agent dosage, etc. can be reduced, thereby improving treatment efficiency.

[0004] In addition to harmful substances, desulfurization waste liquid also contains some valuable substances, such as salts. During the evaporation process, as the water evaporates, these salts in the desulfurization waste liquid will gradually concentrate and crystallize. After crystallization, these salt substances will adhere to the inner wall of the evaporation device, and the salt substances adhered to the inner wall of the evaporation device are difficult to discharge through the discharge pipe of the evaporation device;

[0005] Furthermore, when the desulfurization waste liquid is evaporated using an evaporation device, the steam is usually only used once and then discharged to the outside, which makes it impossible for the steam to be reused.

[0006] Based on this, a desulfurization liquid evaporation device is proposed. Utility Model Content

[0007] 1. Technical issues to be resolved

[0008] In view of the deficiencies of the prior art, the utility model provides a desulfurization liquid evaporation device to solve the problem raised in the background technology: during the evaporation process, as the water evaporates, the salts and other substances in the desulfurization waste liquid will gradually concentrate and crystallize. After crystallization, the salts will adhere to the inner wall of the evaporation device, and the salts adhered to the inner wall of the evaporation device are difficult to discharge through the discharge pipe of the evaporation device;

[0009] Furthermore, when the desulfurization waste liquid is evaporated using an evaporation device, the steam is usually only used once and then discharged to the outside, which makes it impossible for the steam to be reused.

[0039] 1. In the utility model, the driving part in the driving mechanism can drive the rotation of the porous steam spraying pipe through the transmission end. Under the rotation of the porous steam spraying pipe, the two shaft sleeves can be rotated synchronously. When the two shaft sleeves rotate, the rotation of multiple C-shaped frames can be driven. When the multiple C-shaped frames rotate synchronously, the desulfurization waste liquid in the evaporation tank body can be stirred;

[0040] At the same time, the steam generating mechanism can transport the high-pressure steam inside it to the steam inlet pipe through the steam delivery end, and then transport the high-pressure steam to the porous steam spraying pipe through the steam inlet pipe. After the high-pressure steam enters the porous steam spraying pipe, it can be sprayed in the form of multi-point radiation through the porous steam spraying pipe. The sprayed high-pressure steam will enter different height layers of the desulfurization waste liquid, and heat the desulfurization waste liquid in the evaporation tank in all directions to evaporate it.

[0041] 2. In the present invention, salt crystals will precipitate during the evaporation of the desulfurized waste liquid and will adhere to the inner wall, top and bottom of the evaporation tank. Therefore, when each C-shaped frame rotates at a high speed, the bottom end, top end and outer end of each C-shaped frame can respectively scrape off the salt crystals adhered to the bottom of the inner cavity, the top of the inner cavity and the inner wall of the evaporation tank at the same time;

[0043] 3. In the utility model, while the evaporation process is being carried out, the high-pressure steam in the evaporation tank body will continuously rise upward. Therefore, in order to enable the high-pressure steam in the evaporation tank body to be recycled for multiple times, the high-pressure steam rising upward in the evaporation tank body will enter the steam recovery end of the steam generating mechanism through the steam exhaust pipe, and the high-pressure steam in the evaporation tank body will then enter the steam generating mechanism through the steam recovery end, merge with the high-pressure steam in the steam generating mechanism, and re-participate in the circulation. Therefore, under the action of the steam recovery end and the steam delivery end in the steam generating mechanism, the high-pressure steam can be effectively recycled for multiple times, and the energy waste of steam thermal energy can be effectively avoided.

[0044] 4. In the utility model, the high-pressure steam entering the porous steam spray pipe can escape outward through a plurality of steam spray holes. When the high-pressure steam escapes outward through a plurality of steam spray holes, its state is multi-point and radial, and can be evenly distributed in each height layer of the desulfurization waste liquid. Therefore, the coverage range during steam heating is wide, and the evaporation effect of the desulfurization waste liquid is better.

[0045] 5. In the utility model, when each scraper head is in sliding contact with the inner wall of the evaporation tank body, it can better scrape off the salt crystals adhering to the inner wall of the evaporation tank body.

In the utility model, the motor fixing seat is used to fix the motor on the side wall of the evaporation tank body, and the motor can drive the rotation of the driving pulley through the rotation of its output shaft. When the driving pulley rotates, the driven pulley can be driven to rotate through the transmission belt. When the driven pulley rotates, the porous steam spraying pipe can be synchronously driven to rotate through the smooth driving part. When the porous steam spraying pipe rotates, multi-point and radial steam spraying can also be performed in a rotating form;

[0047] At the same time, when the porous steam spray pipe rotates, it can also synchronously drive the rotation of multiple C-type frames, so that the C-type frames can scrape off the salt crystals adhering to the inner wall of the evaporation tank while stirring.

[0048] 7. In the utility model, the high-pressure steam rising upward in the evaporation tank body can enter the steam return pipe through the steam exhaust pipe, and the high-pressure steam entering the steam return pipe can flow back into the steam boiler through the boiler return port and merge with the high-pressure steam in the steam boiler. The merged high-pressure steam enters the steam transmission pipe through the boiler outlet port again, and then the high-pressure steam is transmitted to the steam inlet pipe through the steam transmission pipe, and the high-pressure steam entering the steam inlet pipe will enter the porous steam spray pipe again, and then enter the evaporation tank body through the porous steam spray pipe, and so on. The cycle is repeated, so that the high-pressure steam in the evaporation tank body can be used multiple times in a cyclic manner. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0057] Embodiment 1

[0058] like Figure 1-2 as well as Figure 5 As shown, the utility model provides a technical solution:

[0059] A desulfurization liquid evaporation device, comprising:

[0060] The evaporation tank body 1 has a feed pipe 101 on one side of the top of the evaporation tank body 1, and a plurality of discharge pipes 102 are arranged at the bottom edge of the evaporation tank body 1. The plurality of discharge pipes 102 are circumferentially distributed on the feed pipe 101. An upper assembly hole 103 is opened at the center of the top of the evaporation tank body 1, and a steam exhaust pipe 105 is arranged on one side of the top of the evaporation tank body 1;

[0061] Wherein, each discharge pipe 102 is equipped with a valve 2;

[0062] A porous steam spray pipe 3, one end of which is installed in the inner cavity of the evaporation tank body 1, and the other end of which is passed upward through the upper assembly hole 103;

[0063] Two shaft sleeves 4, the two shaft sleeves 4 are respectively fixedly mounted on the two ends of the porous steam spraying pipe 3 located in the inner cavity of the evaporation tank body 1, the bottom end surface of the shaft sleeve 4 at the bottom can contact the bottom surface of the inner cavity of the evaporation tank body 1, and the top end surface of the shaft sleeve 4 at the top can contact the top surface of the inner cavity of the evaporation tank body 1;

[0064] A plurality of C-shaped frames 5, both ends of each C-shaped frame 5 are respectively fixedly mounted on the corresponding shaft sleeve 4, and the plurality of C-shaped frames 5 are circumferentially distributed between the two shaft sleeves 4;

[0065] Among them, the outer end of each C-shaped frame 5 can be in sliding contact with the inner wall of the evaporation tank body 1, the bottom end of each C-shaped frame 5 can be in contact with the bottom surface of the inner cavity of the evaporation tank body 1, and the top end of each C-shaped frame 5 can be in contact with the top surface of the inner cavity of the evaporation tank body 1;

[0066] A steam inlet pipe 11, which is movably mounted on one end of the outer side of the porous steam spraying pipe 3;

[0067] An air intake pipe bracket 12, the air intake pipe bracket 12 is fixedly mounted on the steam air intake pipe 11, and each leg of the air intake pipe bracket 12 is fixedly mounted on the top of the evaporation tank body 1;

[0068] The driving mechanism comprises a driving part and a transmission end, wherein the driving part is mounted on the evaporation tank body 1, and the transmission end is mounted on an outer end of the porous steam spraying pipe 3;

[0069] Wherein, while the porous steam spraying pipe 3 is driven by the transmission end of the driving mechanism and rotated, the air intake pipe bracket 12 can support and fix the steam intake pipe 11, and while the porous steam spraying pipe 3 rotates, the steam intake pipe 11 can remain stationary on the porous steam spraying pipe 3, that is, the porous steam spraying pipe 3 can move on the steam intake pipe 11, and the movement here includes the movement state such as rotation; and

[0070] The steam generating mechanism comprises a steam supply end and a steam recovery end, the steam supply end is connected to the steam inlet pipe 11 , and the steam recovery end is connected to the steam exhaust pipe 105 .

[0071] In this embodiment, the desulfurized waste liquid of the factory is discharged through a waste liquid discharge pipe (not shown in the figure), and the discharge end of the waste liquid discharge pipe can be plugged and installed in the feed pipe 101. After plugging, the desulfurized waste liquid can be poured into the evaporation tank body 1 through the feed pipe 101. At this time, each valve 2 installed on the discharge pipe 102 is in a tightened state;

[0072] In this state, the driving mechanism and the steam generating mechanism work simultaneously to evaporate the desulfurization waste liquid in the evaporation tank 1;

[0073] Specifically, the driving part in the driving mechanism can drive the rotation of the porous steam spraying pipe 3 through the transmission end. Under the rotation of the porous steam spraying pipe 3, the two shaft sleeves 4 can be rotated synchronously. When the two shaft sleeves 4 rotate, the rotation of the multiple C-shaped frames 5 can be driven. When the multiple C-shaped frames 5 rotate synchronously, the desulfurization waste liquid in the evaporation tank body 1 can be stirred;

[0074] At the same time, the steam generating mechanism can transport the high-pressure steam inside it to the steam inlet pipe 11 through the steam air supply end, and then transport the high-pressure steam to the porous steam spraying pipe 3 through the steam inlet pipe 11. After the high-pressure steam enters the porous steam spraying pipe 3, it can be sprayed in the form of multi-point radiation through the porous steam spraying pipe 3. The sprayed high-pressure steam will enter different height layers of the desulfurized waste liquid, and heat the desulfurized waste liquid in the evaporation tank 1 in all directions and evaporate it.

[0075] In this process, salt crystals will precipitate during the evaporation of the desulfurized waste liquid, and will adhere to the inner wall, top and bottom of the evaporation tank body 1. Therefore, in order to solve this problem, when each C-shaped frame 5 rotates at a high speed, the bottom end, top end and outer end of each C-shaped frame 5 can respectively scrape off the salt crystals adhered to the bottom, top and inner wall of the inner cavity of the evaporation tank body 1 at the same time;

[0076] After evaporation is completed, the valves 2 installed on each discharge pipe 102 are simultaneously unscrewed, and under the action of the rotating scraper of each C-shaped frame 5, the evaporated salt crystals can be better discharged outward through the discharge pipe 102;

[0077] While the evaporation process is in progress, the high-pressure steam in the evaporation tank body 1 will continue to rise upward. Therefore, in order to enable the high-pressure steam in the evaporation tank body 1 to be recycled for multiple times, the high-pressure steam rising upward in the evaporation tank body 1 will enter the steam recovery end of the steam generating mechanism through the steam exhaust pipe 105, and the high-pressure steam in the evaporation tank body 1 will then enter the steam generating mechanism through the steam recovery end, merge with the high-pressure steam in the steam generating mechanism, and re-participate in the circulation. Therefore, under the action of the steam recovery end and the steam gas supply end in the steam generating mechanism, the high-pressure steam can be effectively recycled for multiple times, and the energy waste of steam thermal energy can be effectively avoided.

[0078] Embodiment 2

[0079] like Figure 1-6 As shown, based on the first embodiment, the following improvements are made:

[0080] Further, such as Figure 5 As shown, a lower assembly hole 104 is opened at the center of the bottom of the inner cavity of the evaporation tank body 1;

[0081] like Figure 6 As shown, the porous steam spraying pipe 3 is hollow inside, has a smooth driving portion 301 at one end of the top, and is open, has a plurality of steam spray holes 302 on the side walls of the middle and lower parts, and has a closing portion 303 at the bottom;

[0082] In this embodiment, the high-pressure steam entering the porous steam spraying pipe 3 can escape outward through a plurality of steam spray holes 302. When the high-pressure steam escapes outward through the plurality of steam spray holes 302, its state is multi-point and radial, and can be evenly distributed in each height layer of the desulfurized waste liquid. Therefore, the coverage range during steam heating is wide, and the evaporation effect of the desulfurized waste liquid is better.

[0083] More specifically, in order to optimize the installation method of the porous steam spray pipe 3, as Figure 1 as well as Figure 3-4 As shown, the closing portion 303 is rotatably mounted in the lower assembly hole 104 , and the smooth driving portion 301 passes upward through the upper assembly hole 103 , and after passing through, the smooth driving portion 301 can freely rotate in the upper assembly hole 103 .

[0084] Furthermore, in order to optimize the specific method of movable installation of the steam inlet pipe 11 on the porous steam spray pipe 3, as Figure 1-2 As shown, one end of the bottom of the steam inlet pipe 11 is plugged into the opening of the smooth driving part 301 , and after being plugged in, the steam inlet pipe 11 can rotate freely in the opening of the smooth driving part 301 .

[0085] Further, such as Figure 3-4As shown, each C-shaped frame 5 has a scraper head 501 on one end of the outer side, and each scraper head 501 can be in sliding contact with the inner wall of the evaporation tank body 1 .

[0087] Furthermore, in order to facilitate unloading, Figure 1-2 As shown, each discharge pipe 102 is inclined, and the bottom opening of each discharge pipe 102 is arranged downward.

[0088] Embodiment 3

[0089] like Figure 1-6 As shown, based on the second embodiment, the following improvements are made:

[0090] Further, such as Figure 1-3 As shown, the driving part of the driving mechanism includes a motor 7, which is arranged on the top side of the outer side wall of the evaporation tank body 1, and the output shaft of the motor 7 is arranged upward, and a driving pulley 8 is fixedly installed on the output shaft of the motor 7;

[0091] like Figure 3 As shown, the driving part of the driving mechanism also includes a motor fixing seat 10, which is fixedly mounted on the side wall of the motor 7. The motor fixing seat 10 also has an arc-shaped mounting surface on the side away from the motor 7, and the arc-shaped mounting surface of the motor fixing seat 10 is fixedly mounted on the outer side wall of the evaporation tank body 1;

[0092] The transmission end of the driving mechanism includes a driven pulley 6 and a transmission belt 9 . The driven pulley 6 is fixedly mounted on the smooth driving portion 301 , and the transmission belt 9 is sleeved between the driven pulley 6 and the driving pulley 8 .

[0093] In this embodiment, the above is a specific structure of the driving part and the transmission end in the driving mechanism, specifically: the motor fixing seat 10 is used to fix the motor 7 on the side wall of the evaporation tank body 1, and the motor 7 can drive the rotation of the driving pulley 8 through the rotation of its output shaft. When the driving pulley 8 rotates, the driven pulley 6 can be driven to rotate through the transmission belt 9. When the driven pulley 6 rotates, the porous steam spraying pipe 3 can be synchronously driven to rotate through the smooth driving part 301. When the porous steam spraying pipe 3 rotates, it can also perform multi-point and radial steam spraying in a rotating form;

[0094] At the same time, when the porous steam spraying pipe 3 rotates, it can also synchronously drive the rotation of the multiple C-shaped frames 5, so that the C-shaped frames 5 can scrape off the salt crystals adhering to the inner wall of the evaporation tank body 1 while stirring.

[0095] More specifically, in order to facilitate the installation of the transmission belt 9 on the driven pulley 6 and the driving pulley 8, as shown in FIG. Figure 1-3 As shown, the driven pulley 6 and the driving pulley 8 are in the same horizontal plane.

[0096] Embodiment 4

[0097] like Figure 1-6 As shown, based on the second embodiment, the following improvements are made:

[0098] Further, such as Figure 1-2 As shown, the steam generating mechanism includes a steam boiler 13, which is arranged on one side of the evaporation tank body 1, and the steam supply end of the steam generating mechanism includes a boiler gas outlet port 1301 arranged on one side of the top of the steam boiler 13, and a steam gas delivery pipe 14 is inserted and installed in the boiler gas outlet port 1301, and the steam gas delivery pipe 14 is inserted and installed in one end of the top of the steam inlet pipe 11 at one end away from the steam boiler 13;

[0099] The steam recovery end of the steam generating mechanism includes a boiler return air port 1302 arranged on the other side of the top of the steam boiler 13, and a steam return air pipe 15 is inserted and installed in the boiler return air port 1302. The steam return air pipe 15 is inserted and installed in the steam exhaust pipe 105 at the end away from the steam boiler 13.

[0100] In the present embodiment, the above is a specific structure of the steam generating mechanism, specifically: the high-pressure steam rising upward in the evaporation tank body 1 can enter the steam return pipe 15 through the steam exhaust pipe 105, and the high-pressure steam entering the steam return pipe 15 can flow back into the steam boiler 13 through the boiler return port 1302, and merge with the high-pressure steam in the steam boiler 13, and the merged high-pressure steam enters the steam gas pipe 14 again through the boiler outlet port 1301, and then the high-pressure steam is transported to the steam intake pipe 11 through the steam gas pipe 14, and the high-pressure steam entering the steam intake pipe 11 will enter the porous steam spray pipe 3 again, and then enter the evaporation tank body 1 through the porous steam spray pipe 3, and so on. Therefore, the high-pressure steam in the evaporation tank body 1 can be used multiple times in a cyclic manner.

[0101] More specifically, Figure 1-2 As shown, the boiler gas outlet port 1301 and the boiler gas return port 1302 are both fixedly mounted on the steam boiler 13, and the boiler gas outlet port 1301 and the boiler gas return port 1302 are both connected to the inner cavity of the steam boiler 13;

[0102] The top side of the steam boiler 13 also has a boiler feeding port 1303, and the boiler feeding port 1303 has a valve. By opening the valve installed on the steam boiler 13, water can be injected into the steam boiler 13 through the boiler feeding port 1303. In the working state, the valve on the boiler feeding port 1303 is normally closed.

[0103] In summary, the workflow of the utility model is:

[0104] like Figure 1-6 As shown, the desulfurized waste liquid of the factory is discharged through a waste liquid discharge pipe (not shown in the figure), and the discharge end of the waste liquid discharge pipe can be plugged and installed in the feed pipe 101. After plugging, the desulfurized waste liquid can be poured into the evaporation tank body 1 through the feed pipe 101. At this time, each valve 2 installed on the discharge pipe 102 is in a tightened state;

[0105] In this state, the driving mechanism and the steam generating mechanism work simultaneously to evaporate the desulfurization waste liquid in the evaporation tank 1;

[0106] Specifically, the driving part in the driving mechanism can drive the rotation of the porous steam spraying pipe 3 through the transmission end. Under the rotation of the porous steam spraying pipe 3, the two shaft sleeves 4 can be rotated synchronously. When the two shaft sleeves 4 rotate, the rotation of the multiple C-shaped frames 5 can be driven. When the multiple C-shaped frames 5 rotate synchronously, the desulfurization waste liquid in the evaporation tank body 1 can be stirred;

[0107] At the same time, the steam generating mechanism can transport the high-pressure steam inside it to the steam inlet pipe 11 through the steam air supply end, and then transport the high-pressure steam to the porous steam spraying pipe 3 through the steam inlet pipe 11. After the high-pressure steam enters the porous steam spraying pipe 3, it can be sprayed in the form of multi-point radiation through the porous steam spraying pipe 3. The sprayed high-pressure steam will enter different height layers of the desulfurized waste liquid, and heat the desulfurized waste liquid in the evaporation tank 1 in all directions and evaporate it.

[0108] In this process, salt crystals will precipitate during the evaporation of the desulfurized waste liquid, and will adhere to the inner wall, top and bottom of the evaporation tank body 1. Therefore, in order to solve this problem, when each C-shaped frame 5 rotates at a high speed, the bottom end, top end and outer end of each C-shaped frame 5 can respectively scrape off the salt crystals adhered to the bottom, top and inner wall of the inner cavity of the evaporation tank body 1 at the same time;

[0109] After evaporation is completed, the valves 2 installed on each discharge pipe 102 are simultaneously unscrewed, and under the action of the rotating scraper of each C-shaped frame 5, the evaporated salt crystals can be better discharged outward through the discharge pipe 102;

[0110] While the evaporation process is in progress, the high-pressure steam in the evaporation tank body 1 will continue to rise upward. Therefore, in order to enable the high-pressure steam in the evaporation tank body 1 to be recycled for multiple times, the high-pressure steam rising upward in the evaporation tank body 1 will enter the steam recovery end of the steam generating mechanism through the steam exhaust pipe 105, and the high-pressure steam in the evaporation tank body 1 will then enter the steam generating mechanism through the steam recovery end, merge with the high-pressure steam in the steam generating mechanism, and re-participate in the circulation. Therefore, under the action of the steam recovery end and the steam gas supply end in the steam generating mechanism, the high-pressure steam can be effectively recycled for multiple times, and the energy waste of steam thermal energy can be effectively avoided.

[0111] The above different embodiments can be combined, replaced and used in conjunction with each other.
