A Drying System Containing Combined Reversing Valve

Abstract

The invention discloses a drying system containing a combined reversing valve. The drying system containing the combined reversing valve comprises an air inlet device, an air outlet device, two drying towers, a silencer, an upper piping system, the combined reversing valve and a driving mechanism used for driving the combined reversing valve, wherein the two drying towers comprises a first drying tower and a second drying tower. The air inlet device is communicated with the air inlet end of the combined reversing valve. The silencer is communicated with the air outlet end of the combined reversing valve. An air inlet hole M and an air inlet hole N of the combined reversing valve are connected with the air inlet ends of the first drying tower and the second drying tower respectively. A regeneration hole of the combined reversing valve is connected with the silencer. The upper piping system is arranged between the air outlet ends of the two drying towers. The drying system containing the combined reversing valve is used for solving the problems in the prior art that a changeover valve, generated by four electric butterfly valves of an adsorbing-type drying machine in a combined mode, is frequent in malfunction, and poor in reliability. The drying system containing the combined reversing valve has the advantages of being simple in structure, low in energy consumption, and short in reversing time.

Description

Technical field [0001] The invention relates to the technical field of air drying, and relates to a drying system containing a combined reversing valve. Background technique [0002] The working process of the adsorption dryer is to use pressure swing adsorption and regeneration cycle to make the compressed air flow alternately through two drying tanks filled with adsorbents I and II, that is, one tank absorbs water under high partial pressure (working pressure). When steaming, another tank is analyzed under low partial pressure (close to atmospheric pressure), and then switched according to the set time program. To put it simply, its working process is the regeneration of the adsorption tower Ⅰ, the equalization of the two towers, the regeneration of the adsorption tower Ⅱ, and the regeneration of the tower Ⅰ. The conversion of each process is realized by the switching of four electric butterfly valves A1, B1, A2, and B2. of. The four electric butterfly valves A1, B1, A2, and ...
