Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drying tower, in particular to an adsorption type gas drying machine. BACKGROUND

[0002] The adsorption type drying machine is a representative equipment for adsorbing drying gas, and mainly makes the compressed gas alternately flow through two adsorption tanks A and B filled with adsorbents. When the gas flows through one of the adsorption tanks, the adsorbent in the adsorption tank can adsorb the moisture in the flowing gas. Part of the gas after adsorbing moisture will enter the heater, and the part of the gas after being heated by the heater will enter the other adsorption tank. The heated gas can dry and regenerate the adsorbent in the other adsorption tank, and the cycle is repeated alternately.

[0003] Patent application No. CN201820656102.2 discloses a micro-heat regeneration adsorption type drying machine, which comprises a first adsorption tower and a second adsorption tower. The outer sides of the first adsorption tower and the second adsorption tower are provided with support frames, and the outer sides of the first adsorption tower and the second adsorption tower are also connected with pressure gauges. The top of the first adsorption tower and the second adsorption tower is connected by an upper pipeline, and a pair of regeneration gas regulating valves are installed on the upper pipeline. An exhaust pipe is installed between the two regeneration gas regulating valves. A check valve is connected between the first adsorption tower and the second adsorption tower, and the check valve is located at the bottom of the upper pipeline. The bottom of the check valve is connected with a heater, and the bottom of the heater is provided with a PLC controller. The bottom of the first adsorption tower and the second adsorption tower is connected by a lower pipeline, and the middle of the lower pipeline is provided with an air inlet pipe. The air inlet pipe is provided with air inlet valves on both sides, and the air inlet valves are located on the lower pipeline. A silencer is installed on the top of the lower pipeline. Air flow diffusers are installed at the connection between the top and bottom of the first adsorption tower and the second adsorption tower and the upper and lower pipelines. Molecular sieves are arranged in the first adsorption tower and the second adsorption tower. Through the alternate adsorption and regeneration of the two adsorption towers, the continuous drying of the gas is realized. However, under the condition of continuous impact of compressed gas, the adsorbent is easy to be pulverized. The adsorbent needs to be replaced after a period of use, but the replacement of the adsorbent of such drying machine requires a long time, and the entire adsorption type drying machine needs to be stopped during the replacement period, which causes the drying machine to be unable to be used normally.
