Embodiment 1

[0029] Such as figure 1 , 5 Shown, a kind of high-efficiency, low energy consumption, the device of intelligent bubbling method beach drying, comprise air distribution pipe 4, blower 1 connected with air distribution pipe 4, air distribution pipe 4 connected with blower 1 and buried under the salt field soil The lower air distribution pipe array 9 is connected with ball valves between them. The lower air distribution pipe array 9 is composed of four air distribution pipes 4 arranged horizontally and four air distribution pipes 4 arranged vertically. Through 7, directly 11, and connecting parts of elbow 5, the lower air distribution pipe array 9 is connected with the upper air distribution pipe array 10 attached to the surface of the salt field soil through the vertical connecting pipe 2, and the lower air distribution pipe array is arranged underground, subject to The external influence is small, and the damage to the continuity of the salt field is small. The blower is direc...

Embodiment 2

[0033] Such as Figure 2-4 As shown, in this embodiment, on the basis of Embodiment 1, the further optimization scheme is as follows: the inner center of the air distribution pipe 4 of the lower layer air distribution pipe array 9 is provided with a spiral guide rail 13, and the guide rail 13 is connected with a cleaner 14, and the lower layer is distributed. The trachea array 9 is buried under the soil of the salt pan. During use, silt or accumulated water will enter the lower air distribution pipe array 9. The ball valve 3 provided can discharge the silt or accumulated water when the lower air distribution pipe array 9 is inhaled. Sediment has a certain degree of adhesion and weight, and the blowing effect of the gas may not be good. By setting the sweeper 14 in the air distribution pipe 4 and cooperating with the spiral guide rail 7, when the air is fed into the air distribution pipe 4, the gas drives the sweeper 14 around the guide rail 7. Make a rotary motion to push the ...

Embodiment 3

[0035] Such as figure 1 , 5 As shown, the installation and layout process of an efficient, low energy consumption, and intelligent bubbling beach drying device: in order to meet the requirement that the diameter of the bubbles on the liquid surface is distributed within the range of 1-10mm, and the bubble coverage rate reaches 70-100% Requirements, in this embodiment, the optimal parameters and installation arrangements of the selected pipes are as follows:

[0036] 1) Processing of aeration holes: Process aeration holes with a diameter of 5mm on the bubbling tube 6 with a length of 1m, with an interval of 15cm, and then plug a cellulose acetate cock with a diameter of 7.5mm to the aeration holes;

[0037] 2) Lower layer installation: Lay long-diameter 50mm PVC pipes, connect the 50mm-diameter PVC pipes through elbow 5, tee 8 and cross-way 7, and each section of the four pipelines connected to the upper layer is 1m long, and use a 50mm diameter direct 11 Connected, install t...

Abstract

The invention discloses a high-efficiency, low-energy-consumption and intelligent bubbling beach drying method and a device, and belongs to the field of evaporation of seawater in the sun to make salt. The device provided by the invention utilizes the increase of the gas-liquid mass transfer area of small liquid drops in bubbles and after the bubbles are ruptured in a bubbling process to accelerate the evaporation rate of seawater. The device provided by the invention is divided into two layers, wherein the upper layer comprises a bubbling pipe array and gas distribution pipes vertical to a plurality of rows of bubbling pipes; and the lower layer comprises a large-caliber gas distribution pipe for enabling gas distribution to be more balanced. The device provided by the invention can improve the salt-drying efficiency of concentrated seawater in coastal areas, has the advantages of low energy consumption, small external influence, small continuous damage to salt pans, high rate of return on beach drying of seawater to make salt, high economic value and strong practicability.

Description

technical field [0001] The invention belongs to the field of salt drying by seawater evaporation, and in particular relates to an efficient, low energy consumption and intelligent method and device for beach drying by bubbling. Background technique [0002] Salt is an essential substance to maintain human life and normal development of the human body. It is of great significance to maintain the osmotic pressure of human extracellular fluid, the adjustment of human acid-base balance and the formation of gastric acid. Humans need it, and most life needs it. It can be said that without salt, there will be no human beings and life. Some dynasties implemented a salt monopoly system. Both salt and iron were important sources of fiscal revenue, which were of great significance to stabilizing the economy and consolidating the political power. [0003] At present, the related processes for enhancing the efficiency of salt drying in salt fields mainly include: salt drying by Artemia,...
