Online monitoring and purifying method and system of oil fume

Abstract

The invention provides an online monitoring and purifying method and system of oil fume. The online monitoring and purifying method of the oil fume comprises the following steps that environmental data and original oil fume data in an oil fume channel are collected; according to the collected environment data and the collected original oil fume data, an oil fume severity value in the oil fume channel is calculated; an oil fume exhaust fan is started, and a rotating speed at a corresponding grade is set for the oil fume exhaust fan according to the oil fume severity value and a preset corresponding relation between the rotating speed of the oil fume exhaust fan and the oil fume severity value; whether the oil fume severity value exceeds a preset threshold value or not is judged, if yes, an oil fume purification system is started to purify the oil fume in the oil fume channel, and otherwise, the oil fume purification system does not need to be started. According to the online monitoring and purifying method and system of the oil fume, real-time data of the oil fume concentration, particulate matter and non-methane total hydrocarbon are directly monitored, real and effective oil fume data are provided, and the oil fume monitoring quality and the oil fume purification effect are improved.

Description

technical field [0001] The present application relates to the technical field of oil fume purification, in particular to a method and system for online monitoring and purification of oil fume. Background technique [0002] Due to the limitation of technical level, the oil fume online monitoring system can only simply monitor the start and stop status of each equipment in the oil fume purification system. Generally, as long as the fans and purifiers are normally turned on, it is simply considered that the oil fume emission is also up to standard. Or monitor the operating power and status of the oil fume purification equipment, etc., and judge the working status and cleanliness of the oil fume purification equipment according to the changes of these parameters, so as to estimate that the equipment needs to be cleaned and whether the oil fume emission is up to standard. In fact, due to the operation of the equipment and the oil fume There is no direct relationship between the c...

[0002] Due to the limitation of technical level, the oil fume online monitoring system can only simply monitor the start and stop status of each equipment in the oil fume purification system. Generally, as long as the fans and purifiers are normally turned on, it is simply considered that the oil fume emission is also up to standard. Or monitor the operating power and status of the oil fume purification equipment, etc., and judge the working status and cleanliness of the oil fume purification equipment according to the changes of these parameters, so as to estimate that the equipment needs to be cleaned and whether the oil fume emission is up to standard. In fact, due to the operation of the equipment and the oil fume There is no direct relationship between the concentrations, so technically speaking, these methods are actually equipment monitoring methods, that is, these methods can only monitor the operating status of related equipment, and cannot know the actual situation of oil fume emissions. To be able to truly and effectively monitor the cooking fume emissions, it is necessary to adopt a new method to conduct real-time sampling and analysis of the cooking fume so as to obtain accurate quantitative data of the cooking fume concentration
