如何破解吸附式干燥機的“隧道效應”？

在吸附式干燥機的介紹中，常常會(huì )提到“隧道效應”這個(gè)名詞，那到底什么是“隧道效應”呢？

In the introduction of adsorption dryer, the term "tunnel effect" is often mentioned. What is "tunnel effect"?

我們把干燥塔內氣流分布不均，中間流得快，邊緣流得慢的現象稱(chēng)為“隧@道效應”。

The phenomenon of uneven distribution of air flow in the drying tower, fast flow in the middle and slow flow at the edge is called "tunnel @ channel effect".

形成原因1：壓縮空氣進(jìn)入干燥塔之前，會(huì )通過(guò)一個(gè)氣流分布器，在氣流分布器周?chē)绊敹?，分散排列?zhù)許多小孔，壓縮空氣通過(guò)這些小孔進(jìn)入吸附塔內。而干燥塔出口處的結構與進(jìn)口是相同的，所以在干燥塔中心處的流程短，左右邊緣處的流程就長(cháng)；塔徑越大，邊緣處流程越長(cháng)，就越容易形成“隧#道效應”。

Formation reason 1: before the compressed air enters the drying tower, it will pass through an air distributor. Around and at the top of the air distributor, there are many scattered holes, through which the compressed air enters the adsorption tower. The structure at the outlet of the drying tower is the same as that at the inlet, so the flow at the center of the drying tower is short, and the flow at the left and right edges is long; The larger the diameter of the tower, the longer the flow path at the edge, the easier it is to form "tunnel effect".形成原因2：當氣流分布不均勻時(shí)，在干燥塔中心容易形成一個(gè)“快通隧*道”，而吸附劑填充不夠均勻、緊密，以及雙塔的頻繁切換，壓縮空氣的反復沖擊下，也會(huì )加速“隧*道”的形成。

Formation reason 2: when the air distribution is uneven, a "fast tunnel" is easy to form in the center of the drying tower, and the adsorbent filling is not uniform and tight enough, as well as the frequent switching of the two towers, the repeated impact of compressed air will also accelerate the formation of "tunnel".

這個(gè)問(wèn)題清越節能主要通過(guò)以下兩個(gè)方法來(lái)改善：

There are two ways to improve this problem

1.采用定制的氣流分布器，結合合適的塔體“高徑比”，經(jīng)過(guò)合理的設計計算，在滿(mǎn)足流通量的同時(shí)，還保證氣流能夠均勻合理的分散，并且通過(guò)仿真模擬驗證設計的有用性及可靠性。

1. The customized air distributor, combined with the appropriate "height diameter ratio" of the tower body, through reasonable design and calculation, can not only meet the flow rate, but also ensure that the air flow can be evenly and reasonably dispersed, and verify the usefulness and reliability of the design through simulation.

2.在干燥塔的底部裝填定制的高強度、大顆粒的活性氧化鋁，不但能夠分布氣流，同時(shí)還能起到吸水的作用。

2. The bottom of the drying tower is filled with customized high-strength and large particle activated alumina, which can not only distribute the air flow, but also absorb water.
