Description

Technical Field

[0001] The utility model belongs to the technical field of oil fume purification equipment and relates to a combined oil fume intelligent processing unit. Background Art

[0002] Kitchen fume contains a large amount of grease particles and harmful substances, which have a great impact on human health and the ecological environment. People have gradually paid attention to it and discharged the fume after treatment. However, in practice, there are often problems such as equipment selection mismatch and excessive surface wind speed, which leads to substandard fume treatment effect. At the same time, the laxity in the construction process may also cause smoke leakage. In addition, there is a lack of a clear main responsible unit to take responsibility for the final emission effect. The linkage opening mechanism of the fume treatment equipment and the fan still needs to be intelligently professionally controlled separately, otherwise it can only rely on manual operation of the property. In addition, centralized fume treatment equipment usually serves multiple users, and the selection of exhaust fans is often based on the total air volume, which may cause the exhaust fan to always run at the industrial frequency under partial load conditions, resulting in excessive energy consumption. Therefore, the problems currently faced by the entire fume emission project are long construction period, high cost, high operating energy consumption, and inconvenient maintenance.

[0003] In the prior art, for example, the Chinese patent with publication number CN220728321U discloses a new type of kitchen range hood exhaust machine, which does not completely separate the airflow from the motor, and the fume treatment effect cannot reach 100%. There is still some water vapor inside, which can easily cause motor failure. Secondly, the device is mainly designed for a single user and does not fully consider the frequency conversion energy saving needs in multi-user scenarios. In terms of noise reduction of the range hood equipment, although sound insulation boards are used to reduce noise, the problem of motor heat dissipation is not fully solved, and the noise transmitted by the airflow is not effectively controlled. In addition, the connection between the power equipment and other air ducts is not treated with vibration isolation, which will cause additional noise and vibration when the equipment is running.
