The intelligent control system comprises a microcontroller unit (MCU), wherein a display screen, an oxygen purity transmitter, a flowmeter, a pressure transmitter, a temperature transmitter and a leakage point transmitter are connected to the MCU. The intelligent control system of the VPSA oxygen making machine has the advantages of simple structure and reasonable design, can collect parameters such as field oxygen purity, flow, pressure, temperature and leakage points in real time, and can analyze and process data to automatically regulate technological parameters of the equipment according to curves of the oxygen purity, the flow, the pressure, the temperature and the leakage points, thereby realizing self-adaptive regulative full-automatic running of the whole set of VPSA oxygen making machine.
Description
Technical field
The utility model belongs to vacuum pressure swing adsorption machine Controlling System technical field, is specifically related to the intelligence control system of vacuum pressure swing adsorption machine.
Background technology
The Controlling System that is used for control vacuum pressure swing adsorption machine in the prior art, ubiquity function imperfection level of automation is hanged down and the defectives such as intelligent level is low, this type of Controlling System can not be carried out scene in real time oxygen purity, flow, pressure, temperature, the isoparametric collection of dew point to the vacuum pressure swing adsorption machine, can not automatically adjust to technical parameter by signals such as oxygen purity, flow, pressure, temperature, dew points.
The utility model content
For the problem that prior art exists, the purpose of this utility model is to design the technical scheme of the intelligence control system that a kind of vacuum pressure swing adsorption machine is provided.This Controlling System can be carried out intellectuality control to the vacuum pressure swing adsorption machine, perfect in shape and function, and level of automation is high.
The intelligence control system of described vacuum pressure swing adsorption machine is characterized in that comprising micro-chip, is connected with display screen, oxygen purity transmitter, under meter, pressure unit, temperature transmitter and dew point transmitter on the described micro-chip.
The intelligence control system of described vacuum pressure swing adsorption machine, the by-pass valve control in the vacuum pressure swing adsorption machine that it is characterized in that being connected in parallel on the interface of described micro-chip, described by-pass valve control connects air switch.
The intelligence control system of described vacuum pressure swing adsorption machine is characterized in that connecting safety fuse on the interface of described micro-chip, and described safety fuse connects air switch.
The intelligence control system of above-mentioned vacuum pressure swing adsorption machine, simple in structure, reasonable in design, but the parameters such as the oxygen purity at this system Real-time Collection scene, flow, pressure, temperature, dew point, data analysis is processed, according to oxygen purity, flow, pressure, temperature, dew-point curve technical parameter is automatically adjusted, realize that the self-adaptation of a whole set of vacuum pressure swing adsorption machine is regulated fully automatic operation.
Description of drawings
Fig. 1 is control principle drawing of the present utility model.
Among the figure: the 1-air switch; The 2-safety fuse; The 3-by-pass valve control; The 4-micro-chip; The 5-display screen; 6-oxygen purity transmitter; The 7-under meter; The 8-pressure unit; The 9-temperature transmitter; The 10-dew point transmitter.
Embodiment
Further specify the utility model below in conjunction with Figure of description.
As shown in the figure, the intelligence control system of vacuum pressure swing adsorption machine comprises micro-chip 4, is connected with display screen 5, oxygen purity transmitter 6, under meter 7, pressure unit 8, temperature transmitter 9 and dew point transmitter 10 on the micro-chip 4.Oxygen purity transmitter 6, under meter 7, pressure unit 8, temperature transmitter 9 and dew point transmitter 10 gather respectively oxygen purity, flow, pressure, temperature and the dew point in the vacuum pressure swing adsorption machine; The contents such as the state of the art of display screen 5 centralized displaying equipment, operating parameter, parameters, alarm message.Simultaneously, each by-pass valve control 3 in the vacuum pressure swing adsorption machine that is connected in parallel on the interface of micro-chip 4, by-pass valve control 3 is connected with air switch 1.In order to guarantee safety in utilization, connect safety fuse 2 on the interface of micro-chip 4, safety fuse 2 connects air switch 1.
The utility model can carry out to oxygen purity, flow, pressure, temperature, the dew point of vacuum pressure swing adsorption machine self-adaptation to be regulated, purity, flow, pressure, temperature, dew point signal that process point is collected carry out analyzing and processing, automatically regulate the cycle of operation of breathing equipment, automatically regulate each technical parameter in the cycle of operation, play best energy-saving effect.When oxygen flow increased, purity descends, the oxygen dew point descends (apparatus of load increasing), Controlling System shortened the cycle of operation automatically, makes equipment satisfy purity requirement under high load condition.When oxygen flow reduces, purity improves, the oxygen dew point rises (apparatus of load minimizing), Controlling System automatically prolongs the cycle of operation, make equipment satisfy purity requirement under low condition of loading, heat-up time and Heating temperature that the while is regulated the resurgent gases auxiliary heater automatically according to the operation practical situation are energy-conservation to greatest extent.Automatically regulate simultaneously the waste of resurgent gases according to adsorption cycle, the aperture of automatically regulating air valve guarantees the stable of adsorptive pressure.
This Controlling System has qualified oxygen automatic transport, defective oxygen automatic evacuation function.To detect online to such an extent that the oxygen purity of oxygen purity signal and customer requirements compares, automatic evacuation when oxygen purity does not satisfy customer requirements, automatic transport after satisfying need not manual operation, has realized the fully automatic operation of a whole set of oxygen generation system.This Controlling System has the current interface of teletransmission simultaneously, can need for client's Long-distance Control.
