Description

Technical Field

[0001] This utility model relates to the field of evaporation device technology, specifically a high-salt wastewater evaporation device. Background Technology

[0002] High-salinity wastewater evaporation equipment is an important device for treating high-salinity wastewater and is widely used in industries such as chemical, metallurgical, petroleum, food processing, and mineral resources. These industries often generate large amounts of high-salinity wastewater. Multi-effect evaporation is currently the most widely used high-salinity wastewater evaporation technology. It improves thermal efficiency by connecting multiple evaporation units in series. That is, steam is repeatedly used in multiple evaporators, and the steam in each effect can be used as a heating source for the next effect, thereby saving energy. Multi-effect evaporation technology is suitable for large-scale, high-salinity wastewater treatment.

[0003] However, during use, wastewater is heated by a heat source such as steam, hot water, or combustion, causing the water to evaporate and rise. The water in the high-salt wastewater is evaporated and becomes steam. This steam is cooled by a condenser and becomes liquid water. The salt, minerals, and other impurities in the wastewater do not evaporate with the water due to their solubility limitations, but are concentrated in the wastewater and eventually form salt crystals. The wastewater is transported to the evaporation device, which includes pipes, pumps, regulating valves, and other facilities. As the high-salt wastewater is transported into the evaporation device, it is filtered to remove other solid particulate impurities. Impurities and solid particles in the high-salt wastewater may cause the filtration device to become clogged, especially large salt particles or sediments in the wastewater may accumulate in the filtration device.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1-4As shown, in this embodiment, a high-salt wastewater evaporation device includes an evaporation mechanism 100 and a filter assembly 200. The filter assembly 200 includes a filter tank 201, a bottom plate 205 installed at the bottom of the filter tank 201, a cylindrical filter screen 204 fixedly installed at the upper end of the bottom plate 205, a bearing 213 installed inside the bottom plate 205 of the cylindrical filter screen 204, a rotating rod 210 rotatably connected inside the bearing 213, a servo motor 207 installed at the upper end of the rotating rod 210, and the lower end of the servo motor 207 connected to the upper end of the tank cover 203 by screws. The tank cover 203 is installed on the upper end of the filter tank 201. The inner side of the filter screen 204 is in contact with a brush 209, which is installed on the surface of the first cleaning plate 208 and the second cleaning plate 211. One end of the first cleaning plate 208 and the second cleaning plate 211 is connected to one end of the fixing rod 212 by screws. One end of the fixing rod 212 is fixedly installed on the outside of the rotating rod 210. In actual use, high-salt wastewater is introduced into the filter tank 201. The wastewater is initially filtered through the cylindrical filter screen 204. The cylindrical filter screen 204 can intercept larger particles in the wastewater. After the filter tank 201 has filtered the high-salt wastewater, it is started by the servo motor 207, which drives the rotating rod 210 to rotate. The rotating rod 210 is connected to the fixed rod 212. One end of the fixed rod 212 is connected to the first cleaning plate 208 and the second cleaning plate 211 respectively. As the rotating rod 210 rotates, the fixed rod 212 drives the first cleaning plate 208 and the second cleaning plate 211 to clean. These two cleaning plates contact the inner wall of the cylindrical filter screen 204 through the brush 209. With the help of the brush 209, the impurities attached to the surface of the filter screen are removed. This cleaning process effectively avoids the filter screen being blocked by impurities.

[0022] Through the filter assembly 200, the first cleaning plate 208 and the second cleaning plate 211, and the brush 209, the filter screen is continuously and automatically cleaned by the combined cleaning function of the first cleaning plate 208, the second cleaning plate 211 and the brush 209, reducing the need for manual intervention. During the evaporation treatment of high-salt wastewater, solid particles and salt in the wastewater will gradually adhere to the surface of the cylindrical filter screen 204, forming deposits. The brush 209, by contacting the inner wall of the filter screen and rotating further, can effectively remove the impurities attached to the filter screen, avoiding the occurrence of filter screen blockage. High-salt wastewater can continuously pass through the filter screen, thereby maintaining the system's high-efficiency filtration performance.

[0023] Furthermore, a first scraper 214 and a second scraper 215 are fixedly installed on the outer side of the rotating rod 210. The lower ends of the first scraper 214 and the second scraper 215 contact the upper surface of the bottom plate 205 of the cylindrical filter screen 204. By cleaning the accumulated impurities from the cylindrical filter screen 204, the accumulated impurities will fall onto the bottom plate 205. By opening the discharge valve 206, when the rotating rod 210 rotates, it further drives the first scraper 214 and the second scraper 215 to clean the accumulated impurities from the discharge valve 206 on the upper surface of the bottom plate 205.

[0024] When the rotating rod 210 rotates, the first scraper 214 and the second scraper 215 further drive the first scraper 214 and the second scraper 215 to clean the accumulated impurities from the discharge valve 206 on the upper surface of the bottom plate 205, ensuring that the impurities can be smoothly discharged from the outside of the filter tank 201 and preventing the accumulated impurities from affecting the subsequent processing.

[0025] like Figure 1-2 As shown, a discharge valve 206 is installed inside the base plate 205. The discharge valve 206 has a pipe and passes through the bottom end of the filter tank 201. A discharge pipe 202 is installed on the outside of the cylindrical filter screen 204. The discharge pipe 202 is fixedly installed on the outside of the filter tank 201. A discharge pipe 106 is installed on the outside of the filter tank 201. The upper end of the discharge pipe 106 is installed on the lower end of the water pump assembly 300. A delivery pipe 105 is installed on the upper end of the water pump assembly 300. One end of the delivery pipe 105 is installed on the regulating valve. On one end of 104, the regulating valve 104 is fixedly installed on the upper end of the cover plate 102, the lower end of the cover plate 102 is installed on the upper end of the evaporator 101, and the lower end of the evaporator 101 is fixedly installed on the upper end of the base 103. In actual use, during the filtration process, the discharge valve 206 at the bottom of the filter tank 201 discharges wastewater or impurities through the pipe. Then, in the filter tank 201, wastewater is introduced into the filter tank 201 through the external discharge pipe 202. A cylindrical filter screen 204 is installed inside the filter tank 201 to filter solid impurities in the wastewater. As the wastewater flows, the filter screen captures particulate matter and solid impurities in the water. The high-salt wastewater is connected to the lower end of the pump assembly 300 through the upper end of the discharge pipe 106. The high-salt wastewater is pumped by the pump and transported through the delivery pipe 105 to the regulating valve 104 until it is delivered into the evaporator 101. The high-salt wastewater is first heated by a heat source such as steam, electric heating or other heating equipment. The heating gradually raises the temperature of the wastewater until the boiling point of water. During the evaporation process, the water in the wastewater is removed and converted into steam, while the salt and other dissolved solids in the wastewater are gradually concentrated. After the steam is collected and condensed into water, it can be used as recycled water. The concentrated wastewater residue contains a high concentration of salt and can be further treated or disposed of.

[0026] This utility model provides a high-salt wastewater evaporation device, the specific working principle of which is as follows: First, the wastewater is introduced into the filter tank 201 through the external discharge pipe 202. The filter tank 201 is equipped with a cylindrical filter screen 204 for filtering solid impurities in the wastewater. As the wastewater flows, the filter screen captures particulate matter and solid impurities in the water. The high-salt wastewater is connected to the lower end of the pump assembly 300 through the upper end of the discharge pipe 106. The high-salt wastewater is pumped by the pump and transported to the regulating valve 104 through the delivery pipe 105 until it is delivered into the evaporator 101. The high-salt wastewater is first heated by a heat source such as steam, electric heating or other heating equipment. The heating gradually raises the temperature of the wastewater until the boiling point of water. During the evaporation process, the water in the wastewater is removed and converted into steam, while the salt and other dissolved solids in the wastewater are gradually concentrated. After the steam is collected and condensed into water, it can be used as recycled water. The concentrated wastewater residue contains a high concentration of salt and can be further treated or disposed of. Afterwards, the cylindrical filter screen 204 can intercept larger particles in the wastewater. After the filter tank 201 has filtered the high-salt wastewater, it is started by the servo motor 207, which drives the rotating rod 210 to rotate. The rotating rod 210 is connected to the fixed rod 212. One end of the fixed rod 212 is connected to the first cleaning plate 208 and the second cleaning plate 211 respectively. As the rotating rod 210 rotates, the fixed rod 212 drives the first cleaning plate 208 and the second cleaning plate 211 to clean. These two cleaning plates contact the inner wall of the cylindrical filter screen 204 through the brush 209. With the help of the brush 209, the impurities attached to the surface of the filter screen are removed. This cleaning process effectively avoids the filter screen from being blocked by impurities. The accumulated impurities will fall onto the bottom plate 205. By opening the discharge valve 206, when the rotating rod 210 rotates, it further drives the first scraper 214 and the second scraper 215 to clean the accumulated impurities from the discharge valve 206 on the upper surface of the bottom plate 205.
