Abstract

A range hood internal exhaust filter system includes: a passive range hood separation box, a gas filter device and an odor filter device; the range hood is subjected to a negative pressure suction force generated by an exhaust fan at the range hood separator in the passive range hood separation box, and after the range hood is subjected to a first separation and filtration, the positive pressure wind force pushes the range hood into the lower space of the gas filter device; and a plurality of range hoods are arranged in the upper space. The separation filter cartridge allows the oil and gas to pass through for a second filtration, and the gas after the second filtration is transported to the upper space of the odor filter device where multiple activated carbon filter cartridges are arranged. The large area of activated carbon removes the gas odor, thereby achieving effective large-scale separation of oil and gas and purification of gas odor, greatly increasing the processing speed and air output, and effectively solving the problem of large amounts of oil and gas generated in business premises that cannot be quickly processed.

Description

Range hood internal exhaust filter system

This invention provides a technical field of oil fume purification, especially a technically provided oil fume machine internal emission filtration device system, which separates oil and gas through multiple filter cartridges, purifies gas odor, and ensures large air volume and several times amplified processing speed, efficiency and quality.

Referring to FIG. 1, the oil fume treatment equipment currently installed in the restaurant kitchen of the business premises is a system composed of a smoke hood 11, a high-voltage electrostatic machine 12, air ducts 13, 15 and an exhaust fan 14. The equipment includes: a smoke hood 11 for centrally absorbing the oil fume generated in the restaurant kitchen, a high-voltage electrostatic machine 12, the high-voltage electrostatic machine 12 is provided with an air inlet pipe 121 and an air outlet pipe 122, the air inlet pipe 121 of the high-voltage electrostatic machine 12 is connected to the smoke hood 11 through the air duct 13. The air outlet 111 of the hood 11 is a simple exhaust fan 14. The exhaust fan 14 is simply used for exhausting and pressurizing, that is, wind enters and air exits. If there is oil and gas, oil and gas enter and oil and gas exit. Its function is only to generate negative pressure suction at the air inlet 141 of the exhaust fan 14, and generate positive pressure wind exhaust at the air outlet 142 of the exhaust fan 14. The air duct 15 of the air inlet 141 of the exhaust fan 14 is connected to the air outlet duct 122 of the high-pressure electrostatic motor 12, so that there is negative pressure wind at the high-pressure electrostatic motor 12 and the smoke hood 11. Most restaurant owners do not know that high-voltage electrostatic generators 12 cannot deal with the oil smoke produced by cooking. Because of the law of the inextinguishability of matter, high pressure only breaks the large molecules of oil smoke into multiple small molecules, which are then discharged through the air duct 15 by the outdoor exhaust fan 14. As long as they are not reported, it is fine. But in fact, the molecules of oil smoke are not intercepted and eliminated, so the smell is still there, and there is a need for improvement.

Therefore, in view of the problems existing in the above-mentioned knowledge structure, how to develop a more ideal and practical innovative structure is what consumers are eagerly looking forward to, and it is also the goal and direction that relevant industries must work hard to develop breakthroughs.

In view of this, the creator, based on his many years of experience in manufacturing, developing and designing related products, has designed and carefully evaluated the above-mentioned goals and finally achieved a practical creation.

The main purpose of this invention is to provide a range hood internal emission filtration device system, which introduces the oil and gas from the smoke collector into the front passive oil and gas separation box, and exhausts the oil and gas to the gas filter device through the turbo exhaust fan. The high-efficiency oil and gas separation filter cartridge in the gas filter device performs differential treatment and filtration to remove 99.97% of PM2.5 and other harmful substances, and then the activated carbon filter cartridge in the odor filter device performs the final odor filtration, and then the odor is discharged without odor. There is no need to install an external exhaust pipe, and it can be directly discharged indoors, and it can achieve the maximum processing capacity, speed, efficiency and quality.

To achieve the above purpose, this invention provides a range hood internal emission filter device system, which is aimed at occasions with large amounts of oil smoke, including: a passive oil smoke separation device, a gas filter device and an odor filter device, mainly in that: the oil smoke is generated by the exhaust fan at the oil smoke separator in the passive oil smoke separation box Negative pressure suction separates and filters the oil smoke for the first time, and then the positive pressure wind pushes it into the lower space of the gas filter device; and multiple oil and gas separation filter cartridges are arranged on the upper space, so that the oil and gas pass through for the second filtration, and the gas after the second filtration is transported to the upper space of the odor filter device where multiple activated carbon filter cartridges are arranged. Activated carbon removes gas odors. The oil and gas of the smoke collector are introduced into the pre-passive oil and gas separation box, and the oil and gas are exhausted to the gas filter device through the turbo exhaust fan. The high-efficiency oil and gas separation filter cartridge in the gas filter device performs differential treatment and filtration to remove 99.97% of harmful substances such as PM2.5. The activated carbon filter cartridge in the odor filter device performs the final odor filtration, and the odorless gas is discharged. There is no need to install an external exhaust pipe, and it can be discharged directly indoors. It can effectively purify and separate oil and gas and purify gas odors, greatly increase the processing speed and air volume, and effectively solve the problem of large amounts of oil and gas generated in business premises that cannot be quickly processed.
