Description

Rectifying tower condenser intelligent debugging method and device based on artificial intelligence

Technical Field

The invention relates to the technical field of data processing, in particular to an intelligent debugging method and device for a rectifying tower condenser based on artificial intelligence.

Background

The rectifying tower is a tower type gas-liquid contact device for rectification. By utilizing the property that each component in the mixture has different volatility, namely the vapor pressure of each component is different at the same temperature, the light component (low-boiling-point substance) in the liquid phase is transferred into the gas phase, and the heavy component (high-boiling-point substance) in the gas phase is transferred into the liquid phase, thereby realizing the purpose of separation. The rectifying tower is also a mass and heat transfer device which is widely applied in petrochemical production. The rectifying tower comprises a rectifying chamber, and liquid needing rectifying treatment is rectified through the rectifying chamber in the rectifying tower.

A Condenser (Condenser), a component of a refrigeration system, belongs to one type of heat exchanger, which is capable of converting a gas or a vapor into a liquid, and transferring the heat in the tube to the air in the vicinity of the tube in a rapid manner. The gas rectified by the rectifying tower can be condensed by a condensing chamber of the condenser to form corresponding liquid-phase substances.

In the process of processing petroleum, it is necessary to use the petroleum by dividing it into several fractions according to the boiling point range by means of rectification, which is understood to be the distillation of crude oil.

The steam of each component volatilized by the rectifying tower can be condensed by the condenser, so that the aim of condensing the fractionated gas into liquid is fulfilled. In the existing condensation process, the condenser generally performs the condensation work according to a fixed power, but in the actual fractionation process, the temperatures of distilled and volatilized gases of different components are different, the condensing temperature required for distilling the volatilized gases at a lower temperature is lower, the condensing temperature required for distilling the volatilized gases at a higher temperature is higher, and the prior art cannot determine the working efficiency of the condenser proper according to the quantity of the gases distilled by the rectifying tower and the distilling temperature, so that the energy waste is caused.

As shown in fig. 1, the first usage scenario to which the technical solution provided by the present invention is applied includes a rectification chamber located in a rectification column, and a condensation chamber located at a condenser, where the rectification chamber and the condensation chamber are communicated through a transmission pipeline.

According to the technical scheme provided by the invention, in the actual rectification process, because the gasification temperatures of different liquid phases and distillation gases in the liquid are possibly different, the first distillation temperatures are also different when different distillation gases in the liquid are extracted, and at the moment, the temperature change value can be obtained according to the first distillation temperature and the preset condensation temperature, and can be regarded as the temperature value required to be reduced when the distillation gases are converted into the corresponding liquid in the condenser.

If the second condensation temperature is higher than the first condensation temperature, the heat quantity required to be released by the current distilled gas in the actual condensation scene is less than that in the condensation scene in the preset state, and then the debugging refrigeration power can be reduced, and the electric energy is saved.
