Description

Technical Field

[0001] The invention relates to the technical field of water treatment and air humidification and dehumidification, and in particular to an ultra-low energy consumption steam self-reheating and self-condensing water treatment device. Background Art

[0002] The composition of the sewage treatment system is relatively complex. In actual operation, each component of the system must be strictly supervised and timely regulated. Different types of process treatment units and energy-consuming devices in the system should try to achieve energy-saving goals while meeting treatment requirements. However, in actual operation, sewage treatment is often accompanied by large energy consumption and even causes secondary pollution to water bodies, resulting in the inability to achieve the environmental protection goals of sewage treatment work, and the treatment cost will increase accordingly.

[0003] At present, relatively mature water treatment technologies include: ultrasonic treatment technology, green oxidation water treatment technology, membrane separation water treatment technology, micro-electrolysis water treatment technology, etc. Compared with the mineralization properties of chemical conversion and biodegradation processes, the core of physical wastewater treatment is to achieve pollutant separation and facilitate the resource treatment of pollutants. Its comprehensive economic benefits are outstanding, it can avoid biological pollution, reduce the consumption of chemical agents and the production of secondary pollutants. It is not only a greener and cleaner water treatment technology, but also a water treatment technology that is more conducive to achieving the "dual carbon" goals.

[0004] The continuous increase in energy and material costs has greatly promoted the development of high-efficiency and energy-saving heat exchangers. On the basis of a reasonable design of the heat exchange network, choosing a suitable heat transfer enhancement method can effectively improve the heat transfer efficiency and reduce energy loss. The traditional ways to enhance heat transfer mainly include: (1) Improving the heat transfer coefficient, that is, reducing thermal resistance and improving heat transfer capacity from aspects such as structural design or changing materials. However, this method has limited effect on enhancing heat transfer and is highly dependent on heat-conducting materials. (2) Increasing the average temperature difference of heat transfer. The average temperature difference of heat transfer mainly depends on the inlet and outlet temperatures of the cold and hot fluids and their flow layout. Under the condition of the same inlet and outlet temperatures, the average temperature difference of countercurrent is the largest, and the average temperature difference of downstream is the smallest. However, in the countercurrent arrangement, the highest temperatures of the cold and hot fluids are on the same side of the heat exchanger, which will make the temperature on this side quite high. Therefore, in the actual flow pattern arrangement, the structure should comprehensively consider the effects of increasing the average temperature difference of heat transfer and the countercurrent arrangement, and the application scenarios are limited. (3) Expanding the heat transfer area. Under the condition of less increase in material consumption, try to increase the extended surface (for example, using fins). External tube strengthening usually adopts the method of adding fins. Common fins, typical structures include pin fins, straight fins, ring fins and large sleeves, which not only effectively increase the heat exchange area and aggravate the disturbance of the fluid, but also cut off the development of the boundary layer, and can effectively enhance heat transfer to a certain extent. This method is the most widely used, but the form is relatively simple. At the same time, for steam, the current enhanced heat transfer method does not fully utilize the energy of its vaporization latent heat, resulting in a huge waste of heat energy and increasing the energy consumption of the process.

[0005] Therefore, an ultra-low energy consumption steam self-heating and self-condensing water treatment device is proposed. Summary of the invention

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

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] Reference Figure 1-2 , the present invention provides an ultra-low energy consumption steam self-regeneration and self-condensing water treatment device, including a packing mechanism and a fin-tube heat exchanger 10;

[0036] The packing mechanism is connected to the fin-tube heat exchanger 10 through an air duct to form a relatively closed loop; the packing mechanism is connected to the fin-tube heat exchanger 10 through a water pipe to form a relatively closed loop; the bottom of the fin-tube heat exchanger 10 is connected to a fresh water tank 8; in the packing mechanism, the high-temperature sewage after heating evenly infiltrates to heat and humidify the low-temperature gas flowing upward, and at the same time, the sewage is cooled and flows into the fin-tube heat exchanger 10 to absorb the heat of the high-temperature humid air from top to bottom. The cooled humid air undergoes a dehumidification process in the fin-tube heat exchanger 10 to form droplets, which flow into the fresh water tank 8 for collection;

[0037] A blower 7 is installed on the air duct, and a heating and temperature control component, a sewage tank 16, and a water pump 17 are installed on the water pipe; a sewage outlet (not shown in the figure) is installed on one side of the bottom of the sewage tank 16 to facilitate the discharge of concentrated sewage; a water inlet (not shown in the figure) is installed on the top of the sewage tank 16 to facilitate the replenishment of sewage into the sewage tank 16; the heating and temperature control component is used to heat and control the water temperature in the water pipe; at the beginning of the cycle, the heating and temperature control component and the blower 7 provide a temperature difference and power to the sewage introduced and the air inside the device. When the cycle is stable, the output power of the heating and temperature control component can be flexibly adjusted or stopped according to the actual working conditions. The cycle is carried out by relying on its own temperature difference and potential energy difference, which can make full use of steam self-heating on the basis of extremely low energy consumption, strengthen the heat exchange of water and wet air, and realize independent steam cooling and dehumidification and air heating and humidification processes, thereby realizing physical purification of sewage under low energy consumption and overcoming the shortcomings of high energy consumption and complex procedures of existing water treatment technologies;

[0038] With such an arrangement, the latent heat of steam in the process can be effectively recovered through the material mechanism of the fin-tube heat exchanger 10, so as to achieve an energy-saving method of recycling its own heat, adopt self-heating technology, and improve energy utilization efficiency; in the fin-tube heat exchanger 10, the high-temperature humid air is cooled to achieve self-condensation, and the heat released by the vaporization of steam is effectively absorbed by the cold water, while enhancing the heat transfer, avoiding the waste of latent heat of vaporization; it can make full use of the latent heat released in the process of steam condensing into water droplets, improve the thermal efficiency of the cooling and dehumidification process, and maintain the temperature difference and potential energy difference to drive the humidification and dehumidification process, so as to achieve ultra-low energy consumption water purification, with the characteristics of low consumption, high efficiency and water saving; the present invention has various uses and is suitable for multiple scenarios. The water in the device can be recycled, and the very small loss caused by the condensation of humid air can be compensated by regular water replenishment, which is conducive to saving water resources, simple operation and no risk of secondary pollution.

[0039] According to a further optimized solution, the packing mechanism includes a packing device 3, in which a packing (not shown in the figure) is arranged; a packing device air outlet 2 and a packing device water inlet 5 are arranged at the top of the packing device 3; a packing device air inlet 4 and a packing device water outlet 6 are arranged at the bottom of the packing device 3;

[0040] The filler is a porous material with good internal heat conductivity and is supported by an elastic structure fixed in the shell. The filler height is variable within the range of 0-800mm. The filler is located between the water inlet 5 of the filler device and the water outlet 6 of the filler device, which can avoid direct convection heat transfer between water and air.

[0041] The air outlet 2 of the packing device and the air inlet 4 of the packing device are both fixedly connected and communicated with the air duct; the packing device 3, the air duct, and the finned pipe heat exchanger 10 are connected; the water inlet 5 of the packing device and the water outlet 6 of the packing device are both fixedly connected and communicated with the water pipe; the packing device 3, the water pipe, and the finned pipe heat exchanger 10 are connected;

[0042] With such arrangement, the air at the air inlet 4 of the packing device flows upward evenly along the pores of the packing in the packing device 3, and the hot sewage flowing into the water inlet 5 of the packing device fills the pores of the packing and is fully mixed with the air, thereby greatly increasing the air humidity and improving the clean water output.

[0043] Further optimization scheme, heat exchange tubes 11 are installed in the fin-tube heat exchanger 10, and annular fins 15 are installed on the outer wall of the heat exchange tube 11; the heat exchange tubes 11 are arranged in an S shape; the heat exchange tubes 11 are arranged in three rows and fourteen columns, and are in an S-shaped curved tube shape on the side of the fin-tube heat exchanger 10; the surface of the heat exchange tube 11 is well sealed; the annular fins 15 are neatly arranged on the outer wall of the heat exchange tube 11; water flows from bottom to top in the heat exchange tube 11, and air flows from top to bottom in the fin-tube heat exchanger 10, so as to achieve efficient heat exchange.

[0044] The top and bottom of the finned tube heat exchanger 10 are respectively provided with a heat exchanger air inlet 14 and a heat exchanger air outlet 9; the top and bottom of the heat exchange tube 11 are respectively provided with a heat exchanger water outlet 13 and a heat exchanger water inlet 12; the heat exchanger air inlet 14 and the heat exchanger air outlet 9 are both fixedly connected to and communicated with the air duct; the heat exchanger water outlet 13 and the heat exchanger water inlet 12 are both fixedly connected to and communicated with the water pipe;

[0045] With such arrangement, when sewage leaves the packing device 3 and flows to the heat exchanger water inlet 12 at the bottom of the fin-tube heat exchanger 10, it slowly flows upward through the entire heat exchange tube 11 due to the pressure difference, and the humid air in the fin-tube heat exchanger 10 has a high temperature and humidity after being heated and humidified, and fills the entire fin-tube heat exchanger 10 when flowing downward. Due to the increased gas and liquid contact surface area of ​​the annular fins 15, the humid air is fully cooled, and at the same time, the speed of condensation of the humid air on the wall of the heat exchange tube 11 is accelerated, thereby increasing the amount of steam condensation. When the amount of steam condensation reaches a predetermined value, the stored water in the finned tube heat exchanger 10 is discharged and collected in the fresh water tank 8; the released latent heat of vaporization is also absorbed by the water in the heat exchange tube 11 and fully converted into heat energy for the next cycle; the entire heat exchange process is set as a countercurrent process, so that the temperature of the water outlet 13 of the heat exchanger is closer to the temperature at the air inlet 14 of the heat exchanger, so as to achieve full heat recovery, so that before the next spraying of the filling device 3, only a small amount of heating is needed to reach a very high spraying temperature, so as to achieve an ultra-low energy consumption humidification and dehumidification cycle and obtain high-performance water production.

[0046] A further optimized solution is provided, in which the water pipe includes a first water pipe 201 and a second water pipe 202 located at the bottom of the first water pipe 201; one end of the first water pipe 201 is fixedly connected and connected to the water outlet 13 of the heat exchanger, and the other end is fixedly connected and connected to the water inlet 5 of the filling device; one end of the second water pipe 202 is fixedly connected and connected to the water inlet 12 of the heat exchanger, and the other end is fixedly connected and connected to the water outlet 6 of the filling device; the heating and temperature control component, the sewage tank 16, and the water pump 17 are all installed on the first water pipe 201.

[0047] To further optimize the solution, the heating and temperature control components include:

[0048] A branch pipe 203, one end of which is connected to the first water pipe 201 through a three-way valve 18, and the other end of which is fixedly connected and connected to an end of the first water pipe 201 close to the water inlet 5 of the filling device;

[0049] The pipeline heat exchanger 19 is fixedly mounted on the first water pipe 201 and is located between the three-way valve 18 and the water inlet 5 of the filling device;

[0050] With such arrangement, under the regulation of the three-way valve 18 , the sewage in the first water pipe 201 is heated by the pipeline heat exchanger 19 and mixed with the cold sewage in the branch pipe 203 to reach a preset temperature, providing a basis for subsequent spraying heat exchange in the filling device 3 .

[0051] A further optimized solution is provided, wherein the air duct includes a first air duct 101 and a second air duct 102 located at the bottom of the first air duct 101, wherein one end of the first air duct 101 is fixedly connected and connected to the air inlet 14 of the heat exchanger, and the other end is fixedly connected and connected to the air outlet 2 of the filling device; one end of the second air duct 102 is fixedly connected and connected to the air outlet 9 of the heat exchanger, and the other end is fixedly connected and connected to the air inlet 4 of the filling device; and the blower 7 is fixedly installed on the second air duct 102.

[0052] According to a further optimization scheme, an insulation layer (not shown in the figure) is fixedly connected to the outer walls of the fin-tube heat exchanger 10, the filler device 3, the air duct and the water pipe to reduce heat damage and improve work efficiency.

[0053] Working principle:

[0054] At the beginning of the cycle of the present invention, sewage flows out of the sewage tank 16, and after being pressurized by the water pump 17, the sewage in the first water pipe 201 is heated by the pipeline heat exchanger 19 under the regulation of the three-way valve 18, and is mixed with the cold sewage in the branch pipe 203 to reach a preset temperature, and the hot sewage flows into the packing device 3 from the packing device water inlet 5, and the hot sewage fills the pores of the packing and falls evenly. The low-temperature air at the air inlet 4 of the packing device moves upward under the impetus of the initial velocity, and is fully mixed with the hot sewage inside the packing device 3. After being heated and humidified, the temperature of the humid air increases, and the water vapor contained in the humid air increases. The amount of hot and humid air increases, and it continues to move upward, enters the first air duct 101 along the air outlet 2 of the packing device, continues to move to the air inlet 14 of the heat exchanger and enters the finned pipe heat exchanger 10; at the same time, the temperature of the hot sewage after spraying decreases, and the concentration increases, and it flows into the second water pipe 202 along the water outlet 6 of the packing device, and flows into the heat exchange tube 11 from bottom to top through the water inlet 5 of the packing device, which is opposite to the flow direction of the hot and humid air. The hot and humid air fills the entire finned pipe heat exchanger 10 during the downward movement, and the humid air condenses when it encounters cold on the wall of the heat exchange tube 11 and is discharged and gathered into the fresh water tank 8;

[0055] After one cycle, the sewage flow rate decreases, and after being replenished by the sewage tank 16, it flows through the water pump 17 again, and its flow rate through the pipe heat exchanger 19 is controlled by the opening of the three-way valve 18 to adjust the water temperature of the sewage at the water inlet 5 of the filling device at the beginning of the next cycle. At the same time, the temperature and humidity of the humid air leaving the fin pipe heat exchanger 10 are reduced. When flowing through the blower 7, the air flow rate at the air inlet 4 of the filling device at the beginning of the next cycle can be controlled by adjusting the power of the blower 7, ensuring that the cycle can be carried out continuously under low energy consumption conditions.

[0056] Example 2

[0057] Reference Figure 3The difference between this embodiment and embodiment 1 is that two sets of ultra-low energy consumption steam self-heating and self-condensing water treatment devices are arranged in the upper and lower parts; the ultra-low energy consumption steam self-heating and self-condensing water treatment device located at the top is set as a high-temperature device; the ultra-low energy consumption steam self-heating and self-condensing water treatment device located at the bottom is set as a low-temperature device;

[0058] The first water pipe 201 of the high-temperature device is not provided with a three-way valve 18, a pipeline heat exchanger 19, and a branch pipe 203; the first water pipe 201 of the low-temperature device is connected to the second water pipe 202 of the high-temperature device through a heat exchange box 21; in this embodiment, the heat exchange box 21 is a plate heat exchanger;

[0059] With such arrangement, the temperature of the sewage after the wet air is heated and humidified in the filling device 3 decreases and the concentration increases, and the sewage flows out through the water outlet 6 of the filling device and flows along the second water pipe 202 toward the fin-tube heat exchanger 10. When the temperature of the concentrated sewage is still relatively high, it is not conducive to the condensation of the high-temperature wet air in the fin-tube heat exchanger 10 to produce fresh water. Therefore, a heat exchange box 21 is added to cool the concentrated sewage in the high-temperature stage by adjusting the flow rate of the hot water of the low-temperature stage device flowing through the heat exchange box 21. At the same time, the water temperature of the sewage in the low-temperature stage device is increased and flows to the filling device 3 in the low-temperature stage device to start the circulation of the low-temperature stage device. In this way, the wet air in the fin-tube heat exchanger 10 in the high-temperature stage device is more easily condensed to produce fresh water. At the same time, the low-temperature stage device is used for heat recovery to realize the secondary utilization of heat energy, thereby reducing the energy consumption of the entire device and increasing the output of fresh water.

[0060] Example 3

[0061] Reference Figure 4 , the difference between this embodiment and embodiment 1 is that the pipeline heat exchanger 19 is connected to the heat storage tank 22, and the heat storage tank 22 is connected to the solar collector 24 through the heat conduction pipeline 23;

[0062] With such arrangement, when solar energy resources are abundant, the heat for heating sewage is mainly provided by the solar collector 24, and the excess solar energy is stored in the heat storage tank 22. When solar energy resources are scarce, the heat for heating sewage mainly comes from the heat storage tank 22. When the heat energy in the heat storage tank 22 is exhausted, the heat for heating sewage continues to be provided by the pipeline heat exchanger 19.
