Description
Technical Field
The invention belongs to the field of mechanical devices, and particularly relates to a demisting and water collecting utilization device and a control method thereof.
Background
In foggy weather, the traffic system has many problems because the visual field is influenced; dense fog at a port can prevent ships from stopping orderly; dense fog in airports and highways can cause accidents and road closure, resulting in a series of personal safety hazards and immeasurable economic losses.
With the rapid construction and development of China, how to more efficiently reduce the influence of severe weather on a traffic system and ensure the safety of people becomes a problem which is urgently needed to be solved at present.
The traditional manual defogging method is to use an aircraft to disperse a catalyst into fog, and the method cannot continuously defogg, is high in cost and can cause certain influence on the environment. The existing defogging technology has similar defects, so that the general popularization of the defogging equipment is greatly limited. The defogging problem is becoming more and more serious, and a new defogging method is urgently needed to solve the problem.
While water is a necessity for the survival of all organisms, some organisms can directly utilize salt water, but most higher plants and most mammals must obtain fresh water for survival.
Of all water resources on earth, the brine in oceans, seawater and saline-alkali land accounts for about 97%. The fresh water content is only 2.5% -2.75%, wherein the fresh water resource frozen by glaciers and ice snow accounts for 1.75% -2%, the water content in underground water and soil is 0.5% -0.75%, the surface water content of lakes, marshes and rivers is less than 0.01%, and the atmosphere contains 0.04% of fresh water.
Because of the abundance of salt water resources, various industrial methods for desalinating seawater have been developed, such as distillation, multi-stage flash evaporation, electrodialysis, reverse osmosis, and ion exchange, but these methods require a long construction period of equipment, are costly, relatively complicated to operate, cannot be implemented in situations of limited time and insufficient personnel, and are obviously no longer suitable in arid regions where water resources are scarce, so how to obtain fresh water in regions where fresh water resources are scarce by using an apparatus with simple operation and simple structure is a problem with research prospects.

The embodiment provides a demisting and water collecting utilization device, which comprises a shell 1, a first inertial liquid drop separator 20, a second inertial liquid drop separator, a high-voltage electrode frame 3, a ground electrode frame 4, an exhaust fan 5, an insulator 6 and a water collecting tank, wherein the first inertial liquid drop separator 20 is fixed at an air inlet of the shell 1, a discharge device consisting of the high-voltage electrode frame 3 and the ground electrode frame 4 is installed behind the air inlet inertial liquid drop separator, and the second inertial liquid drop separator 21 is fixed at an air outlet of the shell 1; the high-voltage electrode frame 3 is fixed by an insulator 60 positioned above the high-voltage electrode frame and an insulator 61 positioned below the high-voltage electrode frame, the ground electrode frame 4 is fixed on the shell 1, the exhaust fan 5 is fixed at an air outlet of the shell 1, the second inertial droplet separator 21 is fixed on the shell 1 between the ground electrode frame 4 and the exhaust fan 5, the water collecting tank 70 is arranged below the first inertial droplet separator 20, the water collecting tank 71 is arranged below the second inertial droplet separator 21, and the water collecting tank 72 is arranged below the ground electrode frame 4.
Based on the above embodiment 1, the present invention provides 3 specific embodiments describing a control method of a defogging and water collecting utilization device, which specifically include the following steps:
example 2
In the area affected by the heavy fog weather and with large humidity but small wind speed, the charged particles promote the condensation of water vapor in the air, the high-voltage power supply of the high-voltage electrode frame 3 and the switch of the exhaust fan 5 can be simultaneously turned on for use, and the device can collect water while demisting. Air enters from the air inlet under the action of the exhaust fan 5 and flows through a channel formed by two adjacent corrugated plates of the first inertial liquid drop separator 20. The air continuously changes the flow direction, and the water drops in the air are thrown to the wall surface of the corrugated plate under the combined action of inertia force, centrifugal force and molecular friction force to be separated. The separated water is attached to the corrugated plate surface to form a water film, and is discharged from the first inertial droplet separator 20, and the same process also occurs in the second inertial droplet separator 21. Since the high voltage power is turned on, a strong electric field is formed between the high voltage electrode frame 3 and the ground electrode frame 4, so that the molecules in the air are ionized to generate a large amount of positive ions, negative ions and electrons, the charged particles move under the action of the electric field force and collide with the mist particles, the charged particles are diffused and attached to the mist particles, so that the mist particles are also charged, the charged mist particles move to the electrode frame with the opposite polarity to the electrode frame, finally reach the electrode frame, and are discharged on the electrode frame, so that the mist particles are all gathered on the electrode frame and are deposited under the action of gravity, and then the air is subjected to the same process on the second inertial droplet separator 21. The water collected at this time is composed of two parts, one is water droplets generated by the first inertial droplet separator 20 and the second inertial droplet separator 21, and the other is water droplets generated by the condensation of mist particles on the electrode frame promoted by the charged particles generated between the high voltage electrode frame 3 and the ground electrode frame 4 after the high voltage is applied.
Example 3
Because the effect that charged particles produced by the discharge device promote the condensation of water vapor in the air is relatively poor under the condition that the humidity is too low, in arid areas, such as desert areas with too low humidity and wind speed, the high-voltage power supply of the high-voltage electrode frame 3 can be closed, the switch of the exhaust fan 5 is opened for use, the exhaust fan 5 can be powered by a photovoltaic cell, abundant solar energy resources in the desert areas are fully utilized, and the energy conservation and environmental protection are realized. At this time, air enters from the air inlet, and the same process as in example 2 occurs on the first inertial droplet separator 20 and the second inertial droplet separator 21. The collected water is almost all water droplets generated by the first inertial droplet separator 20 and the second inertial droplet separator 21.
Example 4
In areas with sufficient humidity and wind speed, such as seaside, the effect of the charged particles in promoting the condensation of water vapor in the air is better, and the high-voltage power supply of the high-voltage electrode frame 3 can be turned on, and the exhaust fan 5 can be turned off for use. Air enters from the air inlet, and the same process as in example 2 occurs on the first inertial droplet separator 20, the second inertial droplet separator 21, and the high voltage electrode frame 3 and the ground electrode frame 4, respectively. The water collected at this time is also composed of two parts, one is water droplets generated by the first inertial droplet separator 20 and the second inertial droplet separator 21, and the other is water droplets generated by the condensation of mist particles on the electrode frame promoted by the charged particles generated between the high voltage electrode frame 3 and the ground electrode frame 4 after the high voltage is applied.
In summary, the present invention provides a first inertial droplet separator, a second inertial droplet separator, a high voltage electrode frame, and a ground electrode frame, wherein mist passes through the first inertial droplet separator and the second inertial droplet separator and adheres to the surfaces of the first inertial droplet separator and the second inertial droplet separator under the action of inertial force, centrifugal force, and molecular friction force to form a water film, and then flows into a water collector; and simultaneously, a power supply of the high-voltage electrode frame is switched on, a strong electric field is formed between the high-voltage electrode frame and the ground electrode frame, so that air molecules between the high-voltage electrode frame and the ground electrode frame are ionized to generate a large amount of positive ions, negative ions and electrons, the charged particles move under the action of the electric field force and collide with the mist particles, the charged particles are diffused and attached to the mist particles, the mist particles are charged, and the charged particles move to the electrode frame with the opposite electric polarity to the electrode frame and descend to the water collector under the action of gravity. The invention can realize the effect of water collection while demisting.
The invention can change the running mode of the apparatus according to the condition of the environment, meet the demands for defogging and fresh water resource of different areas, in receiving the influence of heavy fog weather, the humidity is great but the wind speed is not big, can turn on the power of the high-pressure electrode frame and exhaust fan switch to use at the same time, the water collected at this moment is made up of two parts, a part is the water droplet that the separator of the inertia droplet condenses, another part is the water droplet that the charged particle produced between electrode frames promotes the fog particle to condense on the electrode frame after adding the high voltage, the apparatus plays a role of catchmenting while defogging; in arid regions with scarce fresh water resources, such as desert regions with low humidity and low wind speed, the power supply of the high-voltage electrode frame can be closed, the switch of the exhaust fan can be opened, and all the collected water is water drops condensed by the inertial liquid drop separator; and at seashore with enough humidity and wind speed, the power supply of the high-voltage electrode frame can be turned on, the exhaust fan can be turned off, and the collected water also consists of two parts, namely the inertial liquid drop separator and water drops condensed on the electrode frame.
The invention arranges the high-voltage electrode frame and the ground electrode frame, and simultaneously arranges the two inertia liquid drop separators which are positioned at the two sides of the high-voltage electrode frame and the ground electrode frame, thereby fully condensing the mist flowing through and increasing the fresh water collecting efficiency.
