如何破解吸附式干燥机的“隧道效应”？

在吸附式干燥机的介绍中，常常会提到“隧道效应”这个名词，那到底什么是“隧道效应”呢？

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

我们把干燥塔内气流分布不均，中间流得快，边缘流得慢的现象称为“隧@道效应”。

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：压缩空气进入干燥塔之前，会通过一个气流分布器，在气流分布器周围及顶端，分散排列着许多小孔，压缩空气通过这些小孔进入吸附塔内。而干燥塔出口处的结构与进口是相同的，所以在干燥塔中心处的流程短，左右边缘处的流程就长；塔径越大，边缘处流程越长，就越容易形成“隧#道效应”。

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：当气流分布不均匀时，在干燥塔中心容易形成一个“快通隧*道”，而吸附剂填充不够均匀、紧密，以及双塔的频繁切换，压缩空气的反复冲击下，也会加速“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".

这个问题清越节能主要通过以下两个方法来改善：

There are two ways to improve this problem

1.采用定制的气流分布器，结合合适的塔体“高径比”，经过合理的设计计算，在满足流通量的同时，还保证气流能够均匀合理的分散，并且通过仿真模拟验证设计的有用性及可靠性。

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.在干燥塔的底部装填定制的高强度、大颗粒的活性氧化铝，不但能够分布气流，同时还能起到吸水的作用。

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.
