principle

微孔管增氧技術(shù)，采用羅茨鼓風(fēng)機(jī)將空氣送入輸氣管道，輸氣管道將空氣送入微孔曝氣管，由于其孔徑小，可產(chǎn)生大量微細(xì)化氣泡從管壁冒出分散到水中，而且上升速度緩慢，氣泡在水中移動行程長，與水體接觸充分，氣液相間氧分子交換充分，而且還增加了水流的旋轉(zhuǎn)和上下流動。水流的上下流動將上層富含氧氣的水帶人底層，同時(shí)水流的旋轉(zhuǎn)流動將微孔管周圍富含氧氣的水向外擴(kuò)散，實(shí)現(xiàn)養(yǎng)殖池水的均勻增氧。微孔管增氧技術(shù)具有溶氧效率高、改善養(yǎng)殖水體生態(tài)環(huán)境、提高放養(yǎng)密度、增加養(yǎng)殖產(chǎn)量、降低能耗、使用和操作方便等優(yōu)點(diǎn)。

Microporous tube oxygen enrichment technology uses Roots blower to send air into the gas transmission pipeline, and the gas transmission pipeline sends air into the microporous aeration pipe. Because of its small pore size, a large number of micro-fine bubbles can emerge from the pipe wall and disperse into the water, and the rising speed is slow. The bubbles move in the water for a long time, have full contact with the water body, and have sufficient exchange of oxygen molecules between the gas-liquid phase, and also increase the rotation and up-down flow of water flow. The up-and-down flow of the water brings the oxygen-rich water from the upper layer to the bottom, while the rotating flow of the water diffuses the oxygen-rich water around the microporous tube outward to realize the uniform oxygen enrichment of the aquaculture pond water. Microporous tube oxygenation technology has the advantages of high dissolved oxygen efficiency, improved ecological environment of aquaculture water body, increased stocking density, increased aquaculture yield, reduced energy consumption, safe use and convenient operation.

安裝方式主要有兩種：一是盤式安裝法。配備功率為0.1~0.15千瓦/，將曝氣管固定在用鋼筋（直徑為4~6毫米）做成的盤框上，曝氣管盤的總長度15~20米，安裝3~4只/；曝氣管盤總長度30米，裝2~3只/，并固定在離池底10~20厘米處。二是條式安裝法。配備功率為0.1千瓦/，曝氣管總長度為60米左右，管間距為10米左右，高低相差不超過10厘米，并固定在離池底15~20厘米處。微孔增氧設(shè)備的安裝應(yīng)于3月底前完成。

There are two main methods of installation: one is disc installation. Equipped with a power of 0.1~0.15 kW/mu, the aeration pipe is fixed on the tray frame made of steel bars (4~6 mm in diameter), the total length of the aeration pipe tray is 15~20 meters, and 3~4 pieces/mu are installed; The total length of the aeration pipe reel is 30 meters, 2~3 pieces/mu, and fixed at 10~20 cm from the bottom of the tank. The second is the strip installation method. The equipped power is 0.1 kW/mu, the total length of the aeration pipe is about 60 meters, the pipe spacing is about 10 meters, and the height difference is not more than 10 cm, and it is fixed at 15~20 cm from the bottom of the tank. The installation of microporous oxygen enrichment equipment should be completed before the end of March.

使用方法

usage method

根據(jù)水體溶氧變化的規(guī)律，確定開機(jī)增氧的時(shí)間和時(shí)段。一般4~5月，陰雨天半夜開機(jī)；6~10月下午開機(jī)2~3小時(shí)，日出前后開機(jī)2~3小時(shí)，連續(xù)陰雨或低壓天氣，夜間21：00~22：00開機(jī)，持續(xù)到第2天中午；養(yǎng)殖后期，勤開機(jī)，促進(jìn)水產(chǎn)養(yǎng)殖對象生長。有條件的進(jìn)行溶氧檢測，適時(shí)開機(jī)，以保證水體溶氧在6~8毫克/升為佳。

According to the law of dissolved oxygen change in the water body, determine the time and time period of starting up to increase oxygen. Generally from April to May, the machine is turned on at midnight in rainy days; From June to October, the machine is turned on for 2 to 3 hours in the afternoon, and 2 to 3 hours before and after sunrise. In rainy or low pressure weather, the machine is turned on from 21:00 to 22:00 at night, and lasts until noon of the next day; At the later stage of aquaculture, the machine should be turned on frequently to promote the growth of aquaculture objects. Conduct dissolved oxygen detection if conditions permit, and turn on the machine at the right time to ensure that the dissolved oxygen in the water is 6~8 mg/L.

注意事項(xiàng)

主機(jī)在設(shè)置安裝時(shí)應(yīng)注意通風(fēng)、散熱、遮陽及防淋。

When setting and installing the host, pay attention to ventilation, heat dissipation, sunshade and rain-proof.

曝氣管（盤）安裝應(yīng)保持在同一水平面，以利供氣增氧均衡。微孔增氧設(shè)備安裝結(jié)束后，應(yīng)經(jīng)常開機(jī)使用，防止微孔堵塞。每年養(yǎng)殖周期結(jié)束后，應(yīng)及時(shí)清洗。

The installation of aeration pipe (tray) shall be kept at the same level to facilitate the balance of air supply and oxygen increase. After the installation of microporous oxygen enrichment equipment, it should be started frequently to prevent microporous plugging. After the end of the annual breeding cycle, it should be cleaned in time.
