Problems solved by technology

The oil fume purifier has a fixed structure, and the exhaust resistance is large, which affects the smoke exhaust effect. Therefore, the fan at the rear end of the oil fume purifier needs to be used to eliminate the filter resistance, which consumes a lot of energy. After adding the fan, it will also bring noise pollution. And, once Fan failure, the entire building cannot exhaust smoke normally, the system reliability is poor, and the oil fume purifier needs to be replaced and maintained regularly, and the operating cost is high
In addition, the above-mentioned central oil fume purification system cannot adaptively adjust the oil fume purifier according to the operating rate or the wind pressure of the public flue, the system cannot be optimized, and it is not intelligent enough

Embodiment 1

[0034] Such as Figure 1 to Figure 3 As shown, the cooking fume purification system of the building flue kitchen in 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 their respective smoke pipes 2. A range hood 1 has an indoor unit controller 7 , and in this embodiment, the indoor unit controller 7 is installed on the smoke pipe 2 .

[0035] On the roof, there is an air outlet channel 4 connected to the outlet of the common flue 3, and a rotary filter screen 5 and a motor 6 that drives the rotary filter screen to rotate are installed in the air outlet channel 4, and the rotary filter screen 5 is located below the motor 6 And facing the air outlet of public flue 3. In this embodiment, there are four rotary filter screens 5 and they are independently driven by their respective motors 6 . After the system works, oil will remain on the rotary filter screen 5. In this embo...

Embodiment 2

[0046] Such as Figure 4 and Figure 5 As shown, the oil fume purification system of this embodiment is also equipped with a wind pressure sensor 9 in the air outlet channel 4, and the rest of the structure is the same as that of the first embodiment, and will not be described here.

[0047] After the wind pressure sensor 9 is installed, the main controller 8 can control the speed of the motor 6 accordingly by reading the output wind pressure value of the wind pressure sensor 9 .

[0048] The control method of the oil fume purification system includes the following steps:

[0049] ①, range hood 1 is turned on;

[0050] ②. Wind pressure sensor 9 detects changes in wind pressure at the outlet of public flue 3;

[0051] ③, the main controller 8 reads the output wind pressure value P of the wind pressure sensor 9, and compares it with the preset threshold range [P1, P2],

[0052]If P≥P2, then adjust the motor 6 to run at a high gear;

[0053] If P1≤P

Abstract

The invention provides a kitchen fume purification system for a building flue and a control method of the kitchen fume purification system for the building fuel. The kitchen fume purification system is characterized in that an air outlet channel communicated with an outlet of a public flue is formed in a roof, a rotary filter screen and a motor for driving the rotary filter screen to rotate are arranged in the air outlet channel, each range hood is provided with an indoor unit controller, a main controller which can communicate with the indoor unit controllers is arranged on the roof, and themain controller can correspondingly control the rotating speed of the motor by reading starting signals sent by the indoor unit controllers. The roof main controller of the kitchen fume purification system for the building fuel can correspondingly control the rotating speed of the motor by reading the starting signals sent by the indoor unit controllers, so that the rotating speed of the rotary filter screen can be adjusted, the system reliability is high, and the purification effect is good; and the control method can carry out self-adaptive adjustment on the rotating speed of the rotary filter screen according to the start-up rate and an outlet air pressure value of the public flue, the system is more energy-saving, and the system can obtain good fume exhaust and purification effects under different working conditions.

Description

technical field [0001] The invention relates to a building flue system, in particular to a cooking fume purification system and a control method for a building flue kitchen. Background technique [0002] At present, the floors of newly built buildings in cities are generally higher and higher, and the outlets of high-rise public flues are generally set on the top of the floors. In order to purify the oil fumes discharged into the atmosphere, oil fume purification devices are usually installed at the outlets of the public flues. For example, "A Central Oil Fume Purification System and Its Real-time Automatic Control Method" disclosed in the Chinese invention patent application with the application number 201611253474.2 (application publication number CN 106560657 A), the central oil fume purification system is connected in series at the upper end of the public flue There are fume purifiers and fans. The oil fume purifier has a fixed structure, and the exhaust resistance is l...
