Description

Technical Field

[0001] This application relates to the field of water treatment, and in particular to an energy-saving evaporation device for high-salinity water. Background Technology

[0002] Evaporation is a commonly used process in the treatment of high-salt wastewater. It achieves solid-liquid separation through evaporation, thereby converting high-salt wastewater into solid salts for further utilization or treatment.

[0003] There are many ways to evaporate, such as multi-effect evaporation that utilizes secondary steam, and MVR (mechanical vapor recompression) that utilizes the latent heat of secondary steam. These evaporation methods each have their own characteristics, but they all require a high-temperature heat source or electricity to provide the energy needed for evaporation, resulting in generally high operating costs. Utility Model Content

[0004] In order to reduce the energy required in the evaporation process, this application provides a high-salinity energy-saving evaporation device.

[0005] This application provides a high-salinity energy-saving evaporation device, which adopts the following technical solution:

[0006] A high-salinity energy-saving evaporation device includes an evaporation chamber and a salt water atomizing component. The evaporation chamber has an air inlet and an air outlet on its opposite side walls, and a fan is installed at the air inlet. The salt water atomizing component is used to atomize the salt water in the evaporation chamber.

[0007] By adopting the above technical solution, the evaporation box is used to receive the brine to be evaporated, the brine atomizing component is used to atomize the brine in the evaporation box, and the fan can easily introduce external air into the air inlet, which greatly accelerates the air flow speed into the evaporation box, promotes the contact between the atomized brine and the air, and speeds up the evaporation efficiency. No additional heating components are required, thereby reducing the energy required in the evaporation process.

[0008] Optionally, the brine atomizing assembly includes a booster pump and an atomizer. A storage tank is provided on the bottom wall of the evaporation chamber, and the storage tank extends along the depth direction of the evaporation chamber. The booster pump is mounted on the evaporation chamber, and the input end of the booster pump extends into the storage tank. The atomizer is connected to the output end of the booster pump, and the atomizer is used to atomize the brine in the storage tank into the evaporation chamber.

[0009] By adopting the above technical solution, the storage tank is used to hold brine, which makes it easier for the brine to enter the booster pump. The booster pump pumps the brine into the atomizer, which atomizes the brine, making it easier for it to come into contact with the flowing air, quickly removing the water from the brine and improving the evaporation efficiency.

[0010] Optionally, the brine atomizing assembly further includes a connecting pipe, the atomizer is disposed on the inner top wall of the evaporation chamber, and the connecting pipe is used to connect the atomizer to the booster pump.

[0011] By adopting the above technical solution, the atomizer is installed on the inner top wall of the evaporation chamber. Water from the booster pump is pumped into the atomizer through the connecting pipe, which allows the salt water to be atomized and fill the entire evaporation chamber. This increases the space occupied by the atomized salt water and allows it to better contact with the air entering the evaporation chamber, thereby improving the evaporation efficiency.

[0012] Optionally, the height of the bottom wall inside the evaporator gradually decreases along the direction close to the storage tank.

[0013] By adopting the above technical solution, the bottom wall of the evaporator is inclined, which allows the brine in the evaporator to enter the storage tank first, and facilitates the brine to be atomized into the air in the evaporator through the brine atomizing component, thereby improving the evaporation efficiency of the evaporator.

[0014] Optionally, the side walls and top wall of the evaporator are made of a light-transmitting material.

[0015] By adopting the above technical solution, the evaporator can be placed outdoors. When the weather is sunny, the sun's heat can be transferred to the brine through the bottom and side walls of the evaporator, which can accelerate the evaporation of the brine without the need for additional energy consumption, which is in line with the concept of green environmental protection.

[0016] Optionally, a salt outlet is provided on the side wall of the evaporator away from the storage tank, and a salt scraper is also provided inside the evaporator to scrape the solid salt from the bottom wall of the evaporator out of the salt outlet.

[0017] By adopting the above technical solution, when the brine in the evaporation tank gradually evaporates and only solid salt remains, the staff can use a salt scraping machine to scrape the solid salt from the bottom wall of the evaporation tank out of the salt outlet. Since the bottom wall of the evaporation tank is inclined and the salt outlet is located on the side away from the storage tank, the direct outflow of brine from the salt outlet is reduced.

[0018] Optionally, the evaporator is equipped with an exhaust gas sprayer, which is used to spray the air discharged from the air outlet.

[0019] By adopting the above technical solution, the water evaporated from the high-pollution brine is discharged from the evaporation tank in gaseous form along with the exhaust gas. The exhaust gas is polluting, but it can be degraded by the exhaust gas sprayer, thereby ensuring that the discharged air will not pollute the environment.

[0020] Optionally, the salt scraper includes two sprockets, a chain, several scrapers, and a drive motor. The two sprockets are distributed along the inclined direction of the bottom wall of the evaporation chamber and are rotatably connected inside the evaporation chamber. The chain is sleeved on the two sprockets. Several scrapers are distributed along the circumference of the chain and are disposed on the chain. The scrapers are used to abut against the bottom wall of the evaporation chamber. The drive motor is used to drive one of the sprockets to rotate.

[0021] By adopting the above technical solution, when the solid salt on the bottom wall of the evaporator needs to be scraped off, the operator can start the drive motor. The drive motor drives the sprocket to rotate, the sprocket drives the chain to rotate, the chain drives the scraper to move, and the scraper scrapes the solid salt on the bottom wall of the evaporator from the salt outlet.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The atomizing component is used to atomize the brine in the evaporation chamber and fill the entire evaporation chamber. The fan accelerates the airflow in the evaporation chamber, allowing the brine to evaporate quickly.

[0024] 2. The side walls and top wall of the evaporator are made of translucent material, which allows the heat from the sun to accelerate the evaporation of the brine inside the evaporator on sunny days;

[0025] 3. The salt scraper is used to scrape the solid salt formed on the bottom wall of the evaporator out of the evaporator through the salt outlet. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail.

[0030] This application discloses an energy-saving evaporation device for high-salinity water. (Refer to...) Figure 1 and Figure 2A high-salinity energy-saving evaporation device includes an evaporation box 1, a brine atomizing component 2, and a salt scraper 3. The evaporation box 1 has an air inlet 11 and an air outlet 12 at both ends along its length. A fan 13 is fixedly installed at the air inlet 11 to blow air into the evaporation box 1. A storage tank 14 is provided on the inner bottom wall of the evaporation box 1. The storage tank 14 is attached to the side wall where the air outlet 12 is located. The storage tank 14 extends vertically. The height of the inner bottom wall of the evaporation box 1 gradually decreases from the air inlet 11 to the air outlet 12. The peripheral side walls and the top wall of the evaporation box 1 are made of transparent material.

[0031] Reference Figure 1 and Figure 2 The evaporator 1 has an air inlet 11 and a salt outlet 15 on its side wall. The height of the salt outlet 15 is lower than the height of the air inlet 11. The salt scraper 3 includes two sprockets 31, a chain 32, several scrapers 33 and a drive motor 34. The two sprockets 31 are distributed along the inclined direction of the inner bottom wall of the evaporator 1. The length direction of the sprockets 31 is parallel to the width direction of the evaporator 1. The sprockets 31 are rotatably connected to the inner side wall of the evaporator 1. The chain 32 is sleeved on the sprockets 31. Several scrapers 33 are evenly distributed along the circumference of the chain 32. The scrapers 33 are fixedly set on the chain 32. The drive motor 34 is fixedly set on the evaporator 1. The drive motor 34 is fixedly connected to one end of one of the sprockets 31. The scrapers 33 abut against the inner bottom wall of the evaporator 1.

[0032] Reference Figure 1 and Figure 2 The saline atomizing assembly 2 includes a booster pump 21, several atomizers 22, and a connecting pipe 23. The booster pump 21 is fixedly installed on the outer wall of the evaporator 1. The input pipe of the booster pump 21 passes through the evaporator 1 and is located in the storage tank 14. One end of the connecting pipe 23 is fixedly installed on the output end of the booster pump 21. Several atomizers 22 are distributed along the length of the evaporator 1 and are fixedly installed on the inner top wall of the evaporator 1. The connecting pipe 23 is connected to several atomizers 22. The atomizers 22 can be pressure spray atomizers or centrifugal atomizers. An exhaust gas sprayer 4 is also installed on the outer wall of the evaporator 1. The exhaust gas sprayer 4 is connected to the air outlet 12 and is used to introduce alkaline liquid, sodium hypochlorite, or biological bed filtration into the exhaust air.

[0033] The implementation principle of the high-salt water energy-saving evaporation device in this application embodiment is as follows: High-salt wastewater to be evaporated is introduced into the evaporation box 1. Under the action of gravity, the high-salt wastewater enters the storage tank 14. The brine in the storage tank 14 is atomized into the evaporation box 1 by the brine atomizing component 2 through the atomizer 22. Then, air is introduced into the evaporation box 1 by the fan 13 to accelerate the air flow on the surface of the atomized brine, so that the water evaporates quickly. Solid salt adheres to the inner bottom wall of the evaporation box 1. The air in the evaporation box 1 is discharged from the air outlet 12. The discharged air contains exhaust gas. The exhaust gas sprayer 4 filters the exhaust gas through alkaline liquid, sodium hypochlorite or biological bed filtration to reduce environmental pollution. The solid salt adhering to the inner bottom wall of the evaporation box 1 is discharged from the salt outlet 15 by the salt scraper 3 for collection and subsequent utilization.
