Problems solved by technology

[0002] The conventional waste heat (i.e. compression heat) regenerative drying device needs to use part of the product gas as the regeneration gas when regenerating the adsorbent to purge, cool the adsorbent and then vent it, thus consuming a certain amount of product gas; Chinese patent application documents (Application No. : 200610032638.9) Although the disclosed method does not consume regeneration gas, it uses saturated gas at normal temperature as the regeneration gas source; due to the high temperature and high water content of the regeneration gas, the adsorbent absorbs moisture prematurely, and the regeneration is not complete, which improves the dew point of the finished gas temperature, which reduces the adsorption capacity of the adsorbent

Abstract

The invention relates to a compressed gas drying device. The invention aims to provide the device with characteristics of complete regeneration of an adsorbent and lower outlet air pressure dew point. The invention adopts the technical proposal that: in a compressed gas waste heat regeneration high-efficiency drying device, a first path of pipeline is connected with at least two drying pipelines in parallel, and then is connected with an inlet of a freeze drier after the first path of pipelines is orderly connected with two adjusting valves in series; each drying pipeline is orderly connected with a valve and a forward inlet of a drying tower in series; a pipeline on an outlet of the freeze drier is divided into at least two branch paths, wherein, each branch path is connected with a valve, and then is connected to a reverse inlet of the drying tower; a second path of pipeline is divided into two branch paths; the first branch path is divided into at least two shunts; each shunt is connected with a valve, and then is connected with a reverse inlet of the drying tower; the second shunt is connected between the two adjusting valves through a water cooler and a gas-liquid separator in sequence; and the forward inlets of the drying towers are connected with a valve respectively, and then are connected with an air outlet in parallel.
