Problems solved by technology

[0004] 1. Imperfect functions: At present, the controllers of compressed air adsorption dryers in China do not have communication functions, alarm functions, and remote control functions. They only have local control functions, which cannot meet the needs of modern industrial automation control.
[0005] 2. Large amount of maintenance and unreliability: Due to the large number of circuit components and complicated wiring, not only is the product difficult to manufacture, it is not easy to maintain, but also the anti-interference ability is weak, and the stability and reliability are poor
[0006] 3. High maintenance cost: Since some manufacturers of compressed air adsorption dryers do not have the maintenance conditions, they have to send the entire circuit board back to the manufacturer for maintenance. Higher maintenance costs have also brought adverse negative effects to manufacturers of compressed air adsorption dryers

Abstract

The invention provides an adsorption drier controller which includes a gas inletting circuit switch control device and a center controller. The center controller comprises a programmable logic controller that connects with a human-computer interface, an A / D convert module and a communication module for connecting with network; each outputting port of the gas inletting circuit switch control device connects with one outputting port of the programmable logic controller directly or through an intermediate relay respectively, the programmable logic controller is equipped with a control module setaccording with the adsorption drier working program in inside; the adsorption drier detects gas temperature of outlet air and heater outlet in control process, and processes control according with detected result, makes control more accurately and energy-saving. The adsorption drier controller processes operation not only through the human-computer interface, but also remote controlling, and alsoprocesses control through network. The adsorption drier controller is equipped with operation indication and fault warning device, has perfect function.

Description

technical field [0001] The invention relates to the technical field of compressed air purification, in particular to an adsorption dryer controller. Background technique [0002] The compressed air purification industry is an industry that has gradually emerged and developed rapidly in my country in recent years. Under the increasingly tense situation of global available resources, the use of compressed air as a power source is widely used in all walks of life. However, with the increasingly fierce market competition, the requirements for product quality and manufacturing cost are also getting higher and higher, and at the same time, the control performance and energy saving degree of products are also getting higher and higher. [0003] At present, the control systems of compressed air adsorption dryers in China are controlled by relays, contactors, etc., resulting in the control system having many shortcomings such as complex structure as follows: [0004] 1. Imperfect fu...
