A maintenance reminder method for a central flue purification system
A purification system and flue technology, applied in heating methods, oil fume removal, household stoves/stoves, etc., can solve problems such as inability to maintain the impeller, intelligent prompts for impeller maintenance, increased system resistance, and inability to truly reflect the use of centralized filters.

Problems solved by technology
After the flue system has been used for a long time, the centralized filter of the flue will be clogged and its performance will be reduced, which will lead to an increase in system resistance and seriously affect the user's smoke exhaust, so it needs to be replaced in time
At present, people generally judge whether the centralized filter needs to be cleaned or replaced according to the service life or experience, but this maintenance method often cannot truly reflect the use of the centralized filter, and the filter may be replaced too early or too late
In addition, after the central flue system works for a long time, the air volume of the flue motor will decrease at the same speed, and the power will also change greatly, and the accumulation of impeller oil will make the start-up time longer. The impeller of the road main fan is maintained. Similarly, the existing flue system cannot provide intelligent reminders for the maintenance of the impeller, and it is prone to inappropriate maintenance timing.

Embodiment Construction
[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0029] Such as Figure 1 to Figure 4 As shown, the central flue purification system of this embodiment includes range hoods 1 installed on different floors, and the air outlets of each range hood 1 are communicated with the public flue 3 through respective smoke pipes 2. An adjustable check valve 4 is installed on the smoke pipe 2, and the adjustable check valve includes a valve plate 41 and a valve plate driving module 42, and the valve plate 41 is driven to open and close by the valve plate driving module 42. A flow velocity detection module 5 for detecting the flow velocity of the pipeline where the adjustable check valve 4 is located is also installed on the smoke pipe 2 .
[0030] In the public flue 3, a flue main fan 6 and a centralized filter 7 are installed. The flue main fan 6 includes an impeller, and the centralized filter 7 is loc...

A maintenance reminder method for a central flue purification system. The central flue purification system includes range hoods installed on different floors. An adjustable check valve and a flow rate detection module are installed, a flue main fan is installed in the public flue, the flue main fan includes an impeller, and a centralized filter is installed in the public flue. The maintenance reminder method of the central flue cleaning system compares the pipeline flow velocity detected by the flow velocity detection module before and after, and uses the resistance coefficient detection principle to judge whether the centralized filter in the flue needs to be maintained. Compare the start-up time before and after to judge whether the impeller of the flue main fan needs to be maintained, so as to provide more reasonable active maintenance services for the smoke exhaust system of the whole building users, so that the central flue purification system can always be in the best work state.
Description
technical field [0001] The invention relates to a central purification system, in particular to a maintenance reminder method for the central flue purification system. Background technique [0002] In recent years, the user-side adjustable angle valve combined with the centralized filtration and discharge of the main fan at the flue outlet on the roof has begun to be used in some well-decorated buildings. The main fan on the roof, that is, the central range hood, performs frequency conversion + valve preset for users with different operating rates. The flow distribution is achieved at an angle, which can solve the poor smoke exhaust situation of the bottom user to a certain extent, and at the same time effectively control the flow rate and noise of the entire flue system. In addition, in order to purify the oil fume entering the public flue, a centralized flue filter is generally installed in the public flue. Effective purification. After the flue system has been used for ...
