Description

Technical Field

[0001] This invention relates to the field of ammonia evaporation and condensation equipment, and more particularly to a water-saving ammonia evaporation and condenser. Background Technology

[0002] In industries such as chemical engineering, refrigeration, and ammonium nitrate synthesis, ammonia is widely used as a refrigerant, reaction medium, or process raw material due to its excellent thermodynamic properties, environmental friendliness, and economy. Ammonia evaporators and condensers, as core heat exchange equipment, play a crucial role in cooling and liquefying gaseous ammonia and enabling its recycling. Their operating efficiency and water-saving performance directly affect the energy consumption level and operating costs of the entire industrial system. Traditional equipment uses open spray systems, requiring continuous replenishment of fresh water, resulting in high evaporation losses. Furthermore, a large amount of low-grade waste heat generated during industrial production is directly discharged with the cooling water, severely wasting water resources and exhibiting poor environmental performance. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the existing technology has the disadvantages of requiring continuous replenishment of fresh water, high evaporation loss rate, and a large amount of low-grade waste heat generated in industrial production being directly discharged with cooling water, which seriously wastes water resources and has poor environmental performance. To this end, we propose a water-saving ammonia evaporator condenser.

[0004] To achieve the above objectives, this application adopts the following technical solution: a water-saving ammonia evaporator-condenser, comprising an assembly base plate, an ammonia cooling box and an outer casing mounted on the upper end of the assembly base plate, a main pipe body connecting the ammonia cooling box and the outer casing, a dual-medium heat exchanger body installed inside the outer casing, the high-temperature outlet of the ammonia cooling box being connected to the waste heat medium inlet of the dual-medium heat exchanger body via the main pipe body, a distribution water pipe mounted on the top of the outer casing, multiple sets of spray bodies mounted on the outer wall of the distribution water pipe, an output pipe connected to one side of the distribution water pipe, a water tank body mounted at the end of the output pipe away from the distribution water pipe, a vaporization body disposed on one side of the water tank body, the waste heat medium outlet pipe of the dual-medium heat exchanger body being connected to the heat medium inlet of the vaporization body, the ammonia outlet of the vaporization body being connected to the ammonia inlet of the dual-medium heat exchanger body via a pipe, and the heat medium outlet of the vaporization body returning to the low-temperature return port of the ammonia cooling box via a pipe.

[0005] Furthermore, a guide plate is provided at the lower end of the dual-medium heat exchanger body. One end of the guide plate is fixedly connected to the inside of the outer casing, and the other end of the guide plate overlaps the opening of the water tank body. Under the action of gravity, the water falls onto the guide plate and flows into the water tank body with the help of the guide plate, efficiently guiding the spray return water into the water tank body.

[0006] Furthermore, a filter assembly is installed on the inner wall of the water tank body. The filter assembly includes a side plate installed on the inner wall of the water tank body. A first filter body is movably disposed on the inner wall of the side plate, and a second filter body is fixedly disposed on the inner wall of the side plate. The first filter body is located above the second filter body. Water flowing back to the water tank body first passes through the first filter body for coarse filtration to remove large particulate impurities, and then flows through the second filter body for fine filtration to intercept fine impurities.

[0007] Furthermore, the side wall of the water tank body is provided with a movable cavity, and a movable block is slidably connected to the inner wall of the movable cavity. The movable block is fixedly connected to the side plate.

[0008] Furthermore, the inner wall of the movable block is threadedly connected to a threaded adjusting rod, the lower wall of the threaded adjusting rod is rotatably connected to the bottom of the movable cavity, and the upper wall of the threaded adjusting rod is fixedly connected to a motor.

[0009] Furthermore, the outer wall of the side plate is provided with a sliding channel, and a slider body is slidably connected to the inner wall of the sliding channel. A movable rod is fixedly connected to the lower end of the slider body. The movable rod is slidably connected to the bottom channel inside the cavity of the sliding channel. A vibration spring is sleeved on the outer wall of the movable rod. When the vibration spring is relaxed, the slider body is attached to the top of the cavity of the sliding channel. When the water flow impacts the first filter body, it will drive the slider body to slide up and down in the sliding channel. The movable rod moves synchronously with the slider body and squeezes the vibration spring. The rebound effect of the vibration spring generates vibration, shaking off the impurities attached to the surface of the first filter body.

[0010] Furthermore, water pumps are installed on both sides of the bottom of the cavity of the water tank body, one set of water pumps is connected to the output pipe, and the other set of water pumps is connected to the circulation pipe.

[0011] Furthermore, the end of the circulation pipe away from the water pump leads into the cavity of the water tank body and is located at the upper end of the first filter body.

[0012] Furthermore, a water quality monitoring and processing terminal is installed at the bottom of the cavity of the water tank body. The water quality monitoring and processing terminal includes a water quality monitoring template for real-time collection of water quality data from the water tank body. The water quality monitoring template is signal-connected to a decision execution module, which is used to compare the water quality data with a preset threshold and issue a command to start the water pump for filtration. The decision execution module is electrically connected to the water pump, and the decision execution module is signal-connected to an early warning and pre-adjustment module. The early warning and pre-adjustment module is used to adjust the pump speed slightly when the water quality is close to exceeding the standard to prevent water quality deterioration in advance. The early warning and pre-adjustment module is signal-connected to a static anti-stagnation module, which is used to start the water pump for low-flow water circulation after the equipment is shut down to prevent water from deteriorating due to stagnation.

[0013] Furthermore, the static anti-stagnation module is signal-connected to an energy consumption statistics module, which is used to collect energy consumption and water resource consumption data. The energy consumption statistics module is also signal-connected to a problem tracing module, which is used to integrate water quality, energy consumption, and maintenance data.

[0014] The technical effects and advantages of this invention are as follows: In this invention, a closed-loop circulation of spray water is formed by the main body of the water tank, the distribution water pipes, the spray body, and the guide plate. The return water after spraying is recycled through the guide and the filtration components and then reused. There is no need to continuously replenish fresh water, which reduces evaporation loss. By using the ammonia cooling box, the main body of the pipeline, the dual-medium heat exchange body and the gasification body to build a waste heat recovery link, the low-grade industrial waste heat is used in stages for ammonia gasification, replacing external energy sources and avoiding waste heat being discharged with the cooling water. This solves the problems of traditional open spray systems that require continuous replenishment of fresh water, have high evaporation loss rates, and where a large amount of low-grade waste heat generated in industrial production is directly discharged with the cooling water, resulting in serious waste of water resources and poor environmental performance.

[0017] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0018] Reference Figures 1-6 As shown, to address the problems of traditional open-type spray systems, which require continuous replenishment of fresh water, have high evaporation loss rates, and result in the direct discharge of large amounts of low-grade waste heat generated during industrial production with the cooling water, leading to severe water waste and poor environmental protection, the following preferred technical solutions are provided: A water-saving ammonia evaporator-condenser includes an assembly base plate 1. An ammonia cooling box 2 and an outer casing 3 are mounted on the upper end of the assembly base plate 1. A main pipe body 4 connects the ammonia cooling box 2 and the outer casing 3. A dual-medium heat exchange body 5 is installed inside the outer casing 3. The high-temperature outlet of the ammonia cooling box 2 is connected to the waste heat medium inlet of the dual-medium heat exchange body 5 via the main pipe body 4. A distribution water pipe 6 is installed on the top of the outer casing 3. Multiple sets of spray bodies 7 are installed on the outer wall of the distribution water pipe 6. An output pipe 8 is connected to one side of the distribution water pipe 6. A water tank body 9 is installed at the end of the output pipe 8 away from the distribution water pipe 6. A vaporization body 10 is located on one side of the water tank body 9. An ammonia storage tank is connected to the dual-medium heat exchange body 5. The waste heat medium outlet of the dual-medium heat exchange body 5 is connected to the heat medium inlet of the vaporization body 10 via the main pipe body 4. The ammonia outlet of the vaporization body 10 is connected to the ammonia inlet of the dual-medium heat exchange body 5 via a pipe. The heat medium outlet of the vaporization body 10 returns to the low-temperature return port of the ammonia cooling box 2 via a pipe. The medium carrying low-grade waste heat in the ammonia cooling tank 2 is transported to the dual-medium heat exchanger 5 via the main pipeline 4. It first exchanges heat with the ammonia gas entering the dual-medium heat exchanger 5 for preheating. Then, the waste heat medium continues to flow to the vaporization body 10, providing heat for the vaporization of liquid ammonia within the vaporization body 10, completing the cascade utilization of waste heat. The cooled waste heat medium after heat exchange flows back to the ammonia cooling tank 2, forming a closed-loop waste heat system. Simultaneously, water in the water tank 9 is transported to the spray body 7 via the output pipeline 8 and the distribution water pipe 6. The water sprayed from the spray body 7 cools and liquefies the ammonia gas in the dual-medium heat exchanger 5, achieving synergy between ammonia recycling and waste heat utilization. This system replaces external energy sources with low-grade industrial waste heat to achieve energy conservation, and the recycled spray water significantly reduces the amount of fresh water needed, improving water resource utilization. Furthermore, a guide plate 11 is provided at the lower end of the dual-medium heat exchange body 5. One end of the guide plate 11 is fixedly connected to the inside of the outer casing 3, and the other end of the guide plate 11 overlaps the opening of the water tank body 9. After the water sprayed from the spray body 7 cools the dual-medium heat exchange body 5, it falls to the guide plate 11 under the action of gravity. With the guidance of the guide plate 11, it flows smoothly into the water tank body 9, efficiently guiding the spray return water into the water tank body 9, improving the return efficiency, and avoiding impurities splashing due to water flow impact.

[0019] Furthermore, a filter assembly 12 is installed on the inner wall of the water tank body 9. The filter assembly 12 includes a side plate 121 installed on the inner wall of the water tank body 9. A first filter body 122 is movably disposed on the inner wall of the side plate 121, and a second filter body 123 is fixedly disposed on the inner wall of the side plate 121. The first filter body 122 is located above the second filter body 123. A movable cavity 125 is opened in the side wall of the water tank body 9. A movable block 126 is slidably connected to the inner wall of the movable cavity 125. The movable block 126 is fixedly connected to the side plate 121. A threaded adjusting rod 127 is threadedly connected to the inner wall of the movable block 126. The lower wall of the threaded adjusting rod 127 is rotatably connected to the bottom of the movable cavity 125, and a motor is fixedly connected to the upper wall of the threaded adjusting rod 127. Water returning to the main body of the water tank 9 first undergoes coarse filtration through the first filter body 122 to remove large particles of impurities, and then flows through the second filter body 123 for fine filtration to intercept small impurities. When the filter assembly 12 needs maintenance, the motor drives the threaded adjusting rod 127 to rotate, causing the movable block 126 and the side plate 121 connected to the movable block 126 to slide up and down, making it easy to remove the filter assembly 12 for cleaning or replacement. Furthermore, a sliding channel 128 is provided on the outer wall of the side plate 121. A slider body 129 is slidably connected to the inner wall of the sliding channel 128. A movable rod 1210 is fixedly connected to the lower end of the slider body 129. The movable rod 1210 is slidably connected to the bottom channel inside the cavity of the sliding channel 128. A vibration spring 1211 is sleeved on the outer wall of the movable rod 1210. When the vibration spring 1211 is relaxed, the slider body 129 is attached to the top of the cavity inside the sliding channel 128. When water flows and impacts the first filter body 122, it will drive the slider body 129 to slide up and down in the sliding channel 128. The movable rod 1210 moves synchronously with the slider body 129 and squeezes the vibration spring 1211. The rebound of the vibration spring 1211 generates vibration, shaking off impurities attached to the surface of the first filter body 122, preventing the first filter body 122 from clogging and extending the service life of the filter assembly 12. Furthermore, water pumps are installed on both sides of the bottom of the cavity of the water tank body 9. One set of water pumps is connected to the output pipe 8, and the other set of water pumps is connected to the circulation pipe. The end of the circulation pipe away from the water pumps leads into the cavity of the water tank body 9 and is located at the upper end of the first filter body 122. One set of water pumps delivers the filtered clean water in the water tank body 9 to the distribution water pipe 6 through the output pipe 8 to provide a water source for the spray body 7; the other set of water pumps pumps the water at the bottom of the water tank body 9 to the upper end of the first filter body 122 through the circulation pipe, realizing the circulation filtration of water in the water tank body 9. Furthermore, a water quality monitoring and processing terminal 13 is installed at the bottom of the cavity of the water tank body 9. The water quality monitoring and processing terminal 13 includes a water quality monitoring template, which is used to collect water quality data of the water tank body 9 in real time. The water quality monitoring template is signal-connected to a decision execution module, which is used to compare the water quality data with a preset threshold and send a filtration start command to the water pump. The decision execution module is electrically connected to the water pump, and the decision execution module is signal-connected to an early warning and pre-adjustment module, which is used to adjust the pump speed of the water pump when the water quality is close to exceeding the standard. Mild intervention helps to prevent water quality deterioration in advance. The early warning and pre-adjustment module is connected to a static anti-stagnation module. This module activates the water pump for low-flow water circulation after equipment shutdown to prevent the water in the main body of the water tank (9) from becoming stagnant and deteriorating. The static anti-stagnation module is also connected to an energy consumption statistics module, which collects energy consumption data from the water pump and water resource consumption. Furthermore, the energy consumption statistics module is connected to a problem tracing module, which integrates water quality data collected by the water quality monitoring module, energy consumption data collected by the energy consumption statistics module, and equipment maintenance data. The water quality monitoring module collects water quality data from the main body of the water tank (9) in real time and transmits it to the decision execution module. If the water quality is abnormal, the decision execution module instructs the water pump to adjust its operating status. When the equipment is shut down, the static anti-stagnation module activates the water pump for low-flow circulation to prevent the water in the main body of the water tank (9) from becoming stagnant. The energy consumption statistics and problem tracing functions help reduce operation and maintenance costs.

[0020] Specifically, the medium carrying low-grade waste heat in the ammonia cooling box 2 is transported by the main body of the pipeline 4 and first enters the dual-medium heat exchange body 5 inside the outer casing 3. At this time, the dual-medium heat exchange body 5 simultaneously receives ammonia from the vaporization body 10. The waste heat medium and ammonia complete the first heat exchange in the dual-medium heat exchange body 5. After being preheated, the ammonia continues to remain in the heat exchange chamber to wait for cooling, while the waste heat medium flows through the main body of the pipeline 4 to the hot medium inlet of the vaporization body 10. After entering the vaporization body 10, the waste heat medium provides vaporization heat for the liquid ammonia inside, causing the liquid ammonia to be converted into ammonia, completing the second heat exchange. The cooled waste heat medium after heat exchange finally flows back to the low-temperature return port of the ammonia cooling box 2 through the pipeline, forming a waste heat closed loop of ammonia cooling box 2, main body of the pipeline 4, dual-medium heat exchange body 5, main body of the pipeline 4, vaporization body 10, and ammonia cooling box 2, realizing the cascade utilization of low-grade waste heat.

[0021] The ammonia gas generated by the gasification body 10 is transported to the dual-medium heat exchange body 5 through its ammonia gas outlet pipe. In the dual-medium heat exchange body 5, it is first preheated by the waste heat medium and then waits for spray cooling. When the water sprayed by the spray body 7 cools the dual-medium heat exchange body 5, the ammonia gas is liquefied into liquid ammonia in the heat exchange chamber. The liquid ammonia is transported to the external ammonia storage tank through the liquid ammonia outlet pipe of the dual-medium heat exchange body 5 and then flows back to the liquid ammonia inlet of the gasification body 10, completing the ammonia cycle of the gasification body 10, the dual-medium heat exchange body 5, the ammonia storage tank, and the gasification body 10.

[0022] After being purified by the filter assembly 12, the water in the main body 9 of the water tank is drawn by a set of water pumps at the bottom of its cavity and transported to the distribution water pipe 6 on the top of the outer casing 3 through the output pipe 8. The distribution water pipe 6 evenly distributes the water to multiple sets of spray bodies 7 installed on the outer wall. The spray bodies 7 atomize the water and spray it onto the heat exchange surface of the dual-medium heat exchange body 5 to cool the ammonia gas in the cavity.

[0023] After spraying, the water falls under gravity to the guide plate 11 at the lower end of the dual-medium heat exchange body 5. The guide plate 11 guides the return water to the opening of the water tank body 9 through the inclined guide structure. After the return water enters the water tank body 9, it first flows through the first filter body 122 of the filter assembly 12 to remove large particles of impurities, and then passes through the second filter body 123 to intercept fine impurities, thus completing the water purification. At the same time, another set of water pumps at the bottom of the water tank body 9 pumps the water from the bottom back to the upper end of the first filter body 122 through the circulation pipe, thus realizing the closed loop of spray water between the water tank body 9, water pump, output pipe 8, distribution water pipe 6, spray body 7, guide plate 11, water tank body 9, filter assembly 12, circulation pipe, and water tank body 9. The system consists of a water tank body 9, distribution water pipes 6, a spray body 7, and a guide plate 11, forming a closed-loop circulation of spray water. This allows the returned water after spraying to be recycled and purified by the filter assembly 12 before reuse, eliminating the need for continuous replenishment of fresh water and reducing evaporation losses. By utilizing the ammonia cooling box 2, the pipeline body 4, the dual-medium heat exchange body 5, and the gasification body 10, a waste heat recovery link is established. This allows the low-grade industrial waste heat to be used in stages for ammonia gasification, replacing external energy sources and avoiding the discharge of waste heat with the cooling water. This solves the problems of traditional open spray systems, which require continuous replenishment of fresh water, have high evaporation loss rates, and where a large amount of low-grade waste heat generated in industrial production is directly discharged with the cooling water, resulting in serious waste of water resources and poor environmental protection.

[0024] When the filter assembly 12 needs cleaning or replacement, the motor connected to the threaded adjusting rod 127 is started. The motor drives the threaded adjusting rod 127 to rotate, causing the movable block 126, which is threaded to it, to slide upward within the movable cavity 125. Simultaneously, the movable block 126 drives the fixedly connected side plate 121 to rise, and the first filter body 122 and the second filter body 123 on the side plate 121 move upward to the outside of the water tank body 9 for easy maintenance. After maintenance, the motor drives the threaded adjusting rod 127 in the reverse direction to reset the side plate 121. In addition, when the water flow impacts the first filter body 122, it will cause the slider body 129 to move up and down within the sliding channel 128. Simultaneously, the movable rod 1210 squeezes the vibration spring 1211. The vibration generated by the spring's rebound can shake off impurities on the surface of the first filter body 122, preventing clogging.

[0025] In the water quality monitoring and treatment terminal 13 at the bottom of the 9-chamber interior of the water tank, the water quality monitoring template collects data such as pH and turbidity in the water tank in real time and transmits the data to the decision execution module. The decision execution module compares the data with the preset threshold. If the water quality meets the standard, it maintains the current operating status of the two sets of water pumps. If the water quality is close to exceeding the standard, it sends a signal to the early warning and pre-adjustment module, which intervenes slightly by adjusting the water pump speed. If the water quality is seriously exceeding the standard, the decision execution module directly instructs the water pump to increase the circulation filtration intensity and simultaneously links the filter component 12 to improve the purification efficiency.

[0026] When the equipment stops, the static anti-stagnation module receives the shutdown signal and instructs one of the water pumps to operate at low power, driving the water in the main body 9 of the water tank to circulate at a low flow rate to prevent the water from stagnating and deteriorating. At the same time, the energy consumption statistics module collects data such as the operating power, running time and fresh water replenishment of the two sets of water pumps in real time and generates an energy consumption report. If the system experiences continuous water quality abnormalities or a sudden increase in energy consumption, the problem tracing module integrates historical data from the water quality monitoring template, energy consumption records from the energy consumption statistics module and maintenance logs from the filter component 12 to locate the cause of the abnormality and provide a basis for operation and maintenance.

[0027] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
