Description

Multiposition eight-way valve and one-column one-valve novel adsorption device thereof Technical Field The invention belongs to the field of adsorption, and particularly relates to a multi-position eight-way valve and a novel one-column one-valve adsorption device thereof. Background An adsorption apparatus is a device for separating a specific component from a gas or liquid mixture by passing the mixture through an adsorption tower filled with an adsorbent so that a target component is adsorbed to a solid surface. The adsorption can remove organic matters and pollutants in the gas phase and the liquid phase, and can also utilize selective adsorbents to separate and extract available resources in the gas phase and the liquid phase. The equipment most commonly used for adsorption is a fixed bed adsorption system, which operates with the mixture entering from the upper end and exiting from the lower end of the adsorption column. And after the adsorbent in the adsorption tower reaches adsorption saturation, the adsorbent is desorbed from the adsorption tower through the desorption liquid. However, the fixed bed adsorption system needs to repeatedly switch adsorption-desorption modes during operation, so that the problems of high switching frequency of a control valve, high probability of valve failure and the like are caused. In addition, because the single tower can not meet the simultaneous operation of adsorption and desorption and the production period is long, the efficiency is improved by adopting a mode of multi-tower parallel operation. However, the parallel connection of multiple adsorption towers can cause the problems of increased pipelines and valves, increased device cost, complicated switching of valves in the adsorption and desorption states, and the like. The rotary adsorption and desorption fixed bed device can circularly arrange a plurality of towers, pipelines are laid at the tower top in a concentrated manner, and the occupied area and the pipeline length of the adsorption device can be greatly reduced. Chinese patent CN 115540383a discloses a rotary switching type adsorption refrigeration/heat pump air conditioning apparatus in which when an adsorption tower reaches adsorption saturation, an adsorption liquid inlet/outlet pipeline at the top of the tower is rotated to an eluent pipeline, thereby reducing the risk of misoperation of a valve, but the apparatus does not solve the problem of serial use of the adsorption tower, which undoubtedly reduces the use rate of the adsorbent.
