The issue of pressure drop in the regenerative spool valve
Thread Content
Can an increase or decrease in the pressure drop of the regenerative slide valve be used to determine the fluidization state of the regenerative inclined tube? What is the normal range for the pressure drop across the regeneration slide valve? What are the harms of low slide valve pressure drop to production?
This parameter can reflect to a certain extent the quality of inclined tube fluidization, but it is not absolute; we need to consider multiple parameters together for judgment. This value is generally kept between 20-60 Kpa; values that are too high or too low are not ideal. Too low a pressure drop means there is very little catalyst in your pipeline. If you don’t ensure the reaction takes place… you can figure out the subsequent consequences by yourself; P
(A too low pressure drop means there is little catalyst in your pipeline) This isn’t absolute, right? ? The pressure drop across our regenerative spool valve sometimes fluctuates; as the pressure drop decreases from 80 KPa to 60 KPa, the reaction temperature rises. Why is this? I would like to consult an expert.
The pressure drop is low; when the spool valve is opened more, the reaction temperature rises.
This is only relative, relative to a certain degree of slide valve opening! One of the reasons for the resistance that arises in the presence of a catalyst is that, if the opening degree of the slide valve remains constant and other parameters do not change, it is directly related to the amount of catalyst present At this time, there is a large amount of catalyst, so the relative driving resistance is high. With a constant regeneration pressure and a constant pressure in the rear lift pipe, is the pressure drop large or small at this point? The condition of a device is usually analyzed from the perspective of three major balance relationships, and in most cases it is possible to identify the root cause. Sometimes, some calculations are needed to verify things and make the assessment more reliable.
