Intelligent electricity-saving purification sucking and discharging system for kitchens

Abstract

The invention discloses an intelligent electricity-saving purification sucking and discharging system for kitchens. The intelligent electricity-saving purification sucking and discharging system comprises an intelligent controller and a frequency converter, wherein a fume hood is sequentially connected to a high-frequency oil fume purifier, a fan, a water film oil fume treatment device and an airoutlet pipe through a ventilation pipe, and is provided with an oil fume separator, manual air valves and electric air valves at an air suction port, the intelligent controller is connected to the fume hood, the high-frequency oil fume purifier, the fan, the frequency converter and the water film oil fume treatment device, the required air sucking amount is controlled by adjusting the opening degrees of the manual air valves and the number of the opened electric air valves, and the intelligent controller respectively controls the high-frequency oil fume purifier and the water film oil fume treatment device to stop the working after a certain time after the fan is turned off. According to the present invention, the comprehensive oil fume separation and air purification method is used so asto achieve the intelligent energy-saving operation and efficient oil fume sucking and discharging.

Description

technical field [0001] The invention belongs to the field of electrical appliances, and in particular relates to an intelligent purification and extraction system for kitchens. Background technique [0002] At present, range hoods are often used in kitchens to discharge untreated oil fume directly, or to discharge the oil mist after installing a filter in the range hood, which causes serious pollution to the surrounding environment. To purify the oil fume, the general methods include wet purification or adsorption purification. The wet purification uses water spray to condense, wash and accumulate the oil and smoke in the oil mist, and also uses chemical liquid spray To dissolve the oil in the oil fume and to purify it by adsorption method, fiber and activated carbon are used as the adsorption medium for purification. Fiber, activated carbon and other adsorption media are used to absorb the oil mist. Due to the viscosity of the oil mist itself, the pores of the adsorption me...

AI Technical Summary

Problems solved by technology

[0002] At present, range hoods are often used in kitchens to discharge untreated oil fumes directly, or to install filters in the range hoods to filter the oil mist, which will cause serious pollution to the surrounding environment.

To purify the oil fume, the general methods include wet purification or adsorption purification. The wet purification uses water spray to condense, wash and accumulate the oil and smoke in the oil mist, and also uses chemical liquid spray To dissolve the oil in the oil fume and to purify it by adsorption method, fiber and activated carbon are used as the adsorption medium for purification. Fiber, activated carbon and other adsorption media are used to absorb the oil mist. Due to the viscosity of the oil mist itself, the pores of the adsorption medium are easily absorbed. If it is blocked, it needs to be disassembled and washed frequently. If it is not cleaned in time, the purification effect will be greatly reduced, and it will also form a dangerous fire hazard, which is very inconvenient to use

[0003] In today’s large kitchens in hotels and restaurants, there are multiple stoves under each hood. Even if only one stove is used, ventilation is required, and the entire ventilation system must be activated. The fans of the entire ventilation system are working at full capacity, and the air volume cannot be dynamically adjusted. and fan speed, wasting electricity

In addition to the need for ventilation for the working stove, the rest are ineffective ventilation, and even take away the indoor air-conditioning, resulting in a waste of energy. In addition, the current kitchen purification equipment is turned off at the same time as the fan is turned off, so that due to the rotation of the fan The inertia does not stop immediately, and there is still a certain effect of ventilation. In the exhaust duct, there is still residual high-temperature oil fume gas that is discharged outside without purification and pollutes the environment.

[0004] To sum up, the existing oil fume purification and extraction system does not adopt a comprehensive oil fume separation and purification method, the separation of oil fume and water mist is not thorough enough, the filter needs to be cleaned and maintained frequently, and the entire system cannot dynamically adjust the air volume and fan speed to achieve intelligent Energy-saving operation
