Description

Technical Field

[0001] This utility model relates to the field of flash evaporator technology, specifically a high-efficiency flash evaporator. Background Technology

[0002] A flash tank is a container used for the rapid vaporization and vapor-liquid separation of fluids. Since the boiling point of a substance increases with increasing pressure and decreases with decreasing pressure, flash evaporation utilizes this relationship between pressure and boiling point. High-pressure saturated liquids are introduced into a lower-pressure container, where they transform into saturated vapor and saturated liquid at the container's pressure. Once in the flash tank, because the fluid temperature is higher than the corresponding boiling point at that pressure, the fluid rapidly boils and vaporizes, achieving vapor-liquid separation.

[0003] However, in existing flash tanks, the contact area between the high-temperature fluid and the air inside the flash tank is small, and the flash vaporization process mainly occurs at the liquid surface, resulting in low vaporization efficiency. In addition, since the vapor and liquid phases are mixed in the same space without physical separation, the vaporized substances are prone to re-aggregate with the liquefied substances, resulting in incomplete separation and reduced vapor-liquid separation efficiency.

[0004] In view of the technical problems in the prior art, the present invention provides a high-efficiency flash tank, the purpose of which is to solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency flash evaporator includes a tank body, a removable top cover on the top of the tank body, an inlet pipe and an exhaust port on the top cover, a drain port at the bottom of the tank body, a fluid distribution device made of rigid material connected inside the tank body corresponding to the inlet pipe, a filter cover fitted around the fluid distribution device inside the tank body, and a limiting slot for fixing the filter cover at the bottom of the tank body.

[0007] Preferably, the fluid distribution device includes an annular tube, with a first connecting pipe vertically disposed in the middle of the annular tube and communicating with the liquid inlet pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-2This application discloses a high-efficiency flash evaporator, which includes a tank body 1. The top of the tank body 1 is provided with a removable upper cover 2, and the upper cover 2 is provided with a liquid inlet pipe 3 and an exhaust port 4 for introducing the fluid to be treated and discharging the vaporized gas. The bottom of the tank body 1 is provided with a drain port 5 for discharging the liquefied liquid. Inside the tank body 1, corresponding to the liquid inlet pipe 3, a fluid distribution device 6 made of rigid material is connected. The fluid distribution device 6 can evenly distribute the incoming fluid, increasing its contact area with air, thereby improving the flash evaporation efficiency. Inside the tank body 1, corresponding to the fluid distribution device 6, a filter cover 7 is fitted around the periphery. The filter cover 7 can adsorb and intercept impurities in the liquid to ensure the flash evaporation effect. The filter cover 7 can be made of activated carbon fiber, sintered metal fiber felt, ceramic fiber, etc. At the bottom of the tank body 1, corresponding to the bottom periphery of the filter cover 7, a limiting slot 8 is provided to fix it, ensuring the stability of the filter cover 7 during operation.

[0019] Furthermore, the fluid distribution device 6 includes an annular pipe 61. A first connecting pipe 62, which is vertically connected to the inlet pipe 3, is provided in the middle of the annular pipe 61. The first connecting pipe 62 is connected to the inner side of the annular pipe 61 through a second connecting pipe 63. A plurality of longitudinally arranged diverter pipes 64 are arranged in an annular array on the lower side of the annular pipe 61. A plurality of spray nozzles 65 are longitudinally opened on the side of the plurality of diverter pipes 64 facing the filter cover 7. This design allows the fluid to be evenly distributed into the annular pipe 61 after entering the first connecting pipe 62 through the inlet pipe 3, and then evenly sprayed out through the diverter pipes 64 and the spray nozzles 65. This further increases the contact area between the fluid and the air, improves the flash evaporation efficiency, and the spray nozzles 65 correspond to the filter cover 7, so that the sprayed fluid can directly pass through the filter cover 7, which facilitates the filtration and adsorption of impurities on the filter cover 7, further improving the vapor-liquid separation effect.

[0020] To ensure the stability and positional accuracy of the diversion pipe 64, a support seat 9 is provided at the bottom of the tank body 1 corresponding to multiple diversion pipes 64. When the upper cover 2 is closed on the tank body 1, the bottom of the diversion pipe 64 is exactly abutting against the support seat 9, ensuring the stability of the diversion pipe 64 during operation and preventing shaking caused by fluid impact.

[0021] Furthermore, the bottom of the tank 1 is recessed in an arc shape corresponding to the filter hood 7. This design helps to ensure the uniform distribution of liquid at the bottom of the tank 1, reduces liquid accumulation at the bottom of the tank 1, and also facilitates the smooth discharge of liquid phase substances, thereby improving the vapor-liquid separation efficiency.

[0022] To further secure the filter cover 7, a limiting block 10 is provided on the top of the upper cover 2 at the outer periphery of the top of the filter cover 7 to limit its position. When the upper cover 2 is closed, the limiting block 10 abuts against the outer periphery of the top of the filter cover 7, ensuring the stability of the filter cover 7 during operation and preventing displacement caused by fluid impact.

[0023] Furthermore, a separation hood 11 is provided on the lower side of the upper cover 2 corresponding to the exhaust port 4. The design of the separation hood 11 can further separate the vapor phase and liquid phase substances, ensuring that the substances discharged from the exhaust port 4 are mainly vapor phase substances, avoiding the entrainment of liquid phase substances, and improving the thoroughness of vapor-liquid separation.

[0024] When using this high-efficiency flash tank, first remove the upper cover 2, install the fluid distribution device 6 at the liquid inlet of the upper cover 2, install the filter cover 7 inside the tank body 1, and ensure that the filter cover 7 is fixed to the bottom of the tank body 1 through the limiting slot 8. Then, close the upper cover 2 again, ensuring that the limiting block 10 abuts against the top outer periphery of the filter cover 7, and at the same time, the bottom of the diversion pipe 64 abuts against the support base 9. Introduce the fluid to be treated through the liquid inlet pipe 3. After the fluid enters the fluid distribution device 6, it is evenly distributed to each diversion pipe 64 through the annular pipe 61, the first connecting pipe 62 and the second connecting pipe 63, and evenly sprayed out through the spray nozzle 65. The sprayed fluid passes through the filter cover 7, and the impurities in the liquid are adsorbed and intercepted by the filter cover 7. The vaporized gas is discharged from the exhaust port 4 through the separation cover 11, and the liquefied liquid is discharged through the drain port 5.

[0025] In summary, the high-efficiency flash tank of this invention achieves uniform fluid distribution and efficient flash evaporation through a reasonable structural design. Simultaneously, the filter cover 7 and separation cover 11 enhance the vapor-liquid separation effect. The detachable design of the upper cover 2 facilitates comprehensive cleaning of the fluid distribution device 6, filter cover 7, and the interior of the tank 1, ensuring long-term stable operation of the equipment.
