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...

Examples

Embodiment 1

[0027] Such as figure 1 As shown, the present application provides a method for online monitoring and purification of cooking fume, which includes the following steps:

[0028] S1, collecting environmental data and original data of oil fume in the oil fume channel.

[0029] The raw data of oil fume include: oil fume concentration value, oil fume temperature, oil fume humidity, particulate matter concentration value, non-methane total hydrocarbon concentration value.

[0030] Environmental data include ambient temperature, ambient space volume (that is, the size of the surrounding space where oil fumes are generated) and ambient humidity.

[0031] S2. Calculate the severity value of the oil fume in the oil fume channel according to the collected environmental data and the original oil fume data.

[0032] The formula for calculating the severity value of oil fume is:

[0033]

[0034] Among them, E represents the severity value of oil fume; w1 represents the influence weig...

Embodiment 2

[0064] Such as image 3 As shown, the present application provides an oil fume online monitoring and purification system 100, including:

[0065] The data collection module 10 is used for collecting environmental data and original data of oil fume in the oil fume channel.

[0066] The central processing unit 20 is configured to calculate the severity value of the oil fume in the oil fume channel according to the collected environmental data and the original oil fume data.

[0067] The smoke exhaust fan starting module 30 is used to start the smoke exhaust fan, and set the corresponding grade of rotation speed for the smoke exhaust fan according to the value of the bad degree of oil fume and the corresponding relationship between the preset speed of the smoke exhaust fan and the bad degree of oil fume.

[0068] The oil fume purification system startup module 40 is used to judge whether the severity value of the oil fume exceeds the preset threshold, and if so, the oil fume pur...
