Detailed Description

Examples
Referring to the attached drawings in the specification, in the embodiment of the invention, a novel pneumatic conveying device (hereinafter referred to as a device) converts kinetic energy of sea wind into potential energy due to a special structure of the device, and the potential energy can form a certain negative pressure in a negative pressure bin to enable sea water to generate phase change at a certain temperature. The seawater steam is conveyed to a coastal roadbed by utilizing buoyancy of the seawater steam and potential energy formed by seawater wind, and no extra energy consumption exists in the process, wherein the seawater steam comprises a wind-collecting cover 1, a vacuum cavity 4, a diffusion pipe 3, a cooling pipe 9 and a negative pressure bin 14, and the wind-shielding cover has the effect that the wind resistance is larger due to the larger area of the wind-shielding cover, so that the wind-collecting cover 1 can be opposite to the wind direction no matter how the wind direction changes; the wind collecting cover is of a horn mouth special structure and provides larger wind energy for the whole set of system; the air collecting cover 1 is communicated with a vacuum cavity 4, and one end of the vacuum cavity 4, which is far away from the air collecting cover 1, is provided with the diffusion pipe 3; the side wall of the negative pressure bin 14 is provided with a hot seawater inlet 12, the top of the negative pressure bin 14 is provided with a cooling pipe 9, one end of the cooling pipe 9 is provided with a working medium port 6, and the position of the working medium port 6 is connected with the vacuum cavity 4.
Specifically, the sectional area of the second section inside the diffusion tube 3 is increased from small to large.
Specifically, the rear end of the diffusion pipe 3 is provided with a secondary water collector 7 for collecting fresh water carried in seawater.
Specifically, a wind shield 2 is arranged at one end of the diffusion pipe 3 far away from the vacuum cavity 4.
Specifically, a water distributor 13 is arranged at the position of the hot seawater inlet 12, so that seawater is uniformly sprayed into the negative pressure bin 14, and the seawater is uniformly sprayed into the negative pressure bin 14 by using the water distributor.
Specifically, a high-speed nozzle 5 is arranged at one end of the vacuum cavity 4, which is in contact with the air collecting cover 1.
Specifically, the cooling pipe 9 is composed of a vertical structure, a horizontal structure and a vertical structure, a first-level water collector 10 is arranged in the middle of the cooling pipe 9, and the first-level water collector 10 is installed at a low point of the cooling pipe, so that fresh water can be collected conveniently.
Specifically, the lower end of the negative pressure bin 14 is provided with a brine output path 16.
The working principle is as follows: sea wind enters from the wind collecting cover 1 and is sprayed out through the high-speed nozzle 5 with small cross section area. Along with the smaller and smaller sectional area, the pressure of the compressed fluid is gradually increased, the flow rate is also increased, when sea wind passes through the high-speed nozzle 5 at high speed, a vacuum degree is generated at the vacuum cavity 4, so that water vapor around the working medium port 6 is sucked into the device and flows into the diffusion pipe 3 along with the sea wind, and the transmission of the working medium is completed with zero energy consumption;
in the seawater fresh water production base station, seawater at about 65 degrees enters the negative pressure bin 14 from the water distributor 13, seawater wind kinetic energy forms a certain vacuum degree in the negative pressure bin, the seawater is vaporized in a negative pressure state, meanwhile, brine 15 can be generated after flash evaporation, the salt content of the brine 15 is very high, a certain water sealing effect is achieved, and when the amount of the brine reaches a certain volume, the brine is output through a brine output path 16; the vacuum cavity 4 can complete the upward conveying due to the adsorption of the vapor-state water vapor; due to the reduction of the temperature, the seawater is continuously liquefied in the conveying process, the first-stage water collector 10 can output part of fresh water to output a first water collector 11, and the second-stage water collector 7 can output part of fresh water to output a second water collector 8.
