[0002] The principle of spray evaporation is to atomize the concentrated liquid in hot air and evaporate it quickly based on the principle of two-fluid atomization, and achieve solid-liquid separation during the phase change process. According to the environment in which evaporation occurs, it can be divided into the following two categories:

[0003] 1. Technologies for evaporation in a closed environment, such as circulating evaporators, one-way evaporators, evaporators with direct contact heat transfer, and evaporators formed by combining the above-mentioned types of evaporators with MVR technology, are not discussed here because the target scenarios of application are different from those of the present invention.

[0004] 2. Evaporation technologies in open environments, such as spray evaporation and mist evaporation, are greatly affected by the climate environment. However, current evaporation equipment cannot obtain local meteorological conditions in real time, nor can it adjust equipment parameters in real time during the evaporation process, resulting in low evaporation efficiency.

[0014] The beneficial effects of the present invention are:

[0015] 1. Improve efficiency and reduce energy consumption

[0016] (1) This evaporation system forms a unique and innovative model in which multiple factors such as "thermal energy + kinetic energy + particle size + gas-liquid concentration difference" jointly improve the evaporation rate:

[0017] (2) Based on the above technical route, this evaporation system adopts a unique design to give the droplets greater kinetic energy and surface area (speed>100m / s, diameter<50um), reduce the ambient temperature of evaporation (≥60℃), and achieve low boiling point evaporation of the liquid under normal pressure.

[0020] (5) The system has an intelligent judgment and decision-making system that drives the facilities of each part according to the monitoring data: According to the feedback data from the thermometer and pyranometer, when the temperature rises, the initial spray velocity can be appropriately reduced, so that the system can reduce energy consumption at the same efficiency. According to the feedback data from the hygrometer, when the ambient humidity increases, the initial spray velocity can be appropriately increased, so that the system can reduce energy consumption at the same efficiency.

[0021] 2. Reduce losses caused by abnormal weather

[0022] (1) According to the feedback data from the anemometer, when the ambient wind speed is too high, the shielding facilities can be driven to adjust and lower the height of the spray boom. At the same time, according to the wind direction, the spray volume upwind can be increased and the spray volume downwind can be reduced to reduce wind loss.

[0023] (2) Based on the feedback data from the rain gauge, when there is a small amount of precipitation, the rain shielding facilities are driven to provide shelter; when the precipitation is too high, the evaporation system is stopped and the storage facilities are driven to protect the concentrated liquid, thereby reducing rainfall losses.

[0024] 3. Improve safety: Adjust the equipment height and operating status in advance according to meteorological monitoring data to prevent severe weather from damaging the facilities of this system. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the invention in any way.

[0031] Referring to the accompanying drawings, a local meteorological factor intelligent feedback kinetic energy spray evaporation system includes a water pool 1, various meteorological sensors, a water intake module, a pump station module, a two-fluid pipeline module, a spray module 13 and a control system. The water pool 1 is a water pool or a crystallization pool.

[0032] The pool 1 contains raw water to be evaporated, and multiple columns 3 are arranged at intervals around the periphery of the pool 1, and various meteorological sensors are fixedly installed on the top of the columns 3, including thermometers, hygrometers, pyranometers, anemometers, rain gauges, etc.; based on the columns 3, a tension cable net 2 is arranged around the multiple columns 3 and located above the water surface of the pool 1, and the outermost cables in the tension cable net 2 are installed on the columns 3. Cantilevers 4 extending to the inside of the pool 1 are also installed on the columns 3 at the four corners of the pool 1. The other cables in the tension cable net 2 are connected and tensioned with the cantilevers 4 at the four corners of the pool 1, thereby forming a tension cable net located above the water surface. A pulley 12 is arranged at each of the four corners inside the tension cable net 2 to connect the spray module 13 to achieve height adjustment of the spray module 13.

[0033] Furthermore, the column is formed by connecting two single columns and a crossbeam to improve the stability of the column.

[0034] The water intake module is a corrosion-resistant submersible pump 10 or a corrosion-resistant self-priming pump, which is generally installed in the pool 1. The raw water is pumped into the pump station equipment box 9 on one side of the pool for further pressurization. After pressurization, the water is sent to the spray module 13 through the two-fluid pipeline module.

[0035] The pump station module is arranged in the pump station equipment box 9, including: (1) an air filtration submodule 901, which uses an air salt spray filter to filter the air entering the system, reduce the salt content in the air in the equipment, and ensure the normal operation of the system; (2) an air boost submodule 902, which uses a high-speed air ring fan to increase the inlet air temperature and provide a wind pressure air source to the spray module; (3) a liquid boost submodule 903, which uses a corrosion-resistant high-pressure pump to increase the raw water pressure and then send it to the spray module; (4) a heat exchange submodule 904, which uses a heat exchange device to provide heat source to the air entering the box, so that the air heats the water to improve the spray evaporation efficiency. The heat source of the heat exchange device comes from a photovoltaic and thermal integrated solar energy system to reduce the cost of the heat source.

[0036] The two-fluid pipeline module includes: (1) a water pipe submodule, which uses a water pipe 8 made of food-grade PP material with an insulation layer, one end of the water pipe 8 is connected to the water outlet 906 of the high-pressure pump in the pump station equipment box 9 through a booster water pipe 7, and the other end is connected to the flat-shooting two-fluid spray gun of the spray module 13 through a branch pipe, and the upper part of the water pipe 8 is arranged along the cantilever 4 on the tensioned cable net 2; (2) an air pipe submodule, which uses an air pipe 5 made of food-grade PP material with an insulation layer, one end of the air pipe 5 is connected to the air outlet 907 of the high-speed air ring fan in the pump station equipment box 9 through a booster air pipe 6, and the other end is connected to the flat-shooting two-fluid spray gun of the spray module 13 through a branch pipe, and the upper part of the air pipe 5 is arranged along the cantilever 4 on the tensioned cable net 2; the function of the two-fluid pipeline module is to send the high-pressure hot air generated by the fan and the high-pressure water generated by the water pump to the flat-shooting two-fluid spray gun for spraying operation.

[0037] The spray module 13 uses a plurality of flat-shooting two-fluid spray guns as spray guns, each of which is connected to the lower end of the boom, and the upper end of the boom is connected to the sling 11, and the sling 11 passes through the pulley 12 of the tensioning cable net 2 and is connected to the motor-driven winch, and the motor-driven winch can control the lifting of the boom. The motor and the winch are both arranged on the column 3. The flat-shooting two-fluid spray gun obtains high-pressure water source and high-pressure hot air from the water pipe 8 and the air duct 5, and sprays salt mist with a small droplet diameter to the surroundings. The spray diameter of each spray gun is 10 meters and the height is 2 to 3 meters. The specifications of the spray gun can also be replaced according to the specific situation of the body.

[0038] A circle of louver walls 14 is also arranged around the pool 1. The louver walls 14 are installed between adjacent columns 3 and are higher than the wall of the pool 1. The opening and closing of the blades of the louver walls 14 and the opening amplitude are controlled by the control system through corresponding motors to protect the spray guns in the pool from strong winds.

[0039] The control system has an intelligent judgment and decision-making system, which adjusts the operation of each part according to the monitoring data of the meteorological sensor:

[0040] (1) According to the feedback data from the thermometer and the pyranometer, when the ambient temperature rises, the control system lowers the initial spray velocity of the spray gun, so that the system reduces energy consumption at the same efficiency; otherwise, the initial spray velocity is increased;

[0041] (2) According to the feedback data from the hygrometer, when the ambient humidity increases, the control system can increase the initial spray velocity of the spray gun, so that the system can reduce energy consumption at the same efficiency; otherwise, the initial spray velocity is reduced;

[0042] (3) Based on the feedback data from the anemometer, when the ambient wind speed is too high, the control system lowers the opening amplitude of the shutter wall in the corresponding direction, or closes the shutter wall, and adjusts and lowers the height of the boom to make the spray gun closer to the water surface. At the same time, according to the wind direction, the spray volume in the upwind direction is increased and the spray volume in the downwind direction is reduced to reduce wind loss and improve the overall evaporation efficiency.

[0043] (4) Based on the feedback data from the rain gauge, when there is a small amount of precipitation, the rain shielding facilities of the water pool are driven to shield the water pool; when the precipitation is too much, the operation of the evaporation system is stopped and the storage facilities are driven to protect the concentrated liquid to reduce the loss caused by rainfall.

[0044] The rain-shielding facility is a conventional rain-shielding film or rain-shielding curtain. It is controlled by an electric unfolding mechanism. The storage facility is composed of a brine-retaining pool, a pipeline, and a water pump beside the crystallization pool. When it rains heavily, the concentrated liquid in the crystallization pool is pumped into the brine-retaining pool. After the rain, the concentrated liquid is pumped from the brine-retaining pool into the crystallization pool. Since the rain-shielding facility and the storage facility can adopt conventional devices in the art, they are not improvements of the present invention, so they are not described in detail in the present invention.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Those skilled in the art should understand that the specific implementation modes of the present invention may be modified or replaced by equivalents with reference to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the pending claims.
