Oil fume purification processors in the catering and food processing industries generate large amounts of oil fume, as well as harmful substances such as carbon monoxide, sulfur dioxide, and hydrocarbons during the production process. Among them, 3,4-benzo is a strong carcinogen. The existing range hoods and exhaust fans only directly discharge the oil fumes and harmful gases generated at the work site into the atmosphere. Although this ensures clean air in the operation room, it only transfers pollution and still causes environmental pollution. Currently, oil fume pollution has become a major hotspot in air pollution. Oil fume purifier: widely used in hotels, restaurants, enterprises, and catering industries. It is an environmental protection equipment for treating oil fume exhaust gas, with a purification efficiency of over 95%, designed and manufactured in accordance with the requirements of the national "Emission Standards for Cooking Fumes" GB18483-2001 and the technical requirements and testing technical specifications for cooking fume purification equipment "(HJ/T62-2001).

Product Introduction of Oil Fume Purifier:

Due to the complex composition of kitchen fumes, in addition to producing carbon monoxide, carbon dioxide, and particulate matter during combustion, various harmful gases are also emitted. Moreover, the particle size distribution of particulate matter in the fumes is wide and the composition changes greatly, making purification difficult. Conventional techniques are difficult to completely eliminate pollution.

This product adopts a dual function of mechanical purification and electrostatic purification. After the smoke containing exhaust gas is sucked into the pipeline by the fan, it first enters the primary device - the purification rectifier room. The gravity inertia purification technology is used, and the special structure inside the room gradually separates and balances the large particle pollutants. The separated large oil droplets flow into the oil tank and are discharged under their own gravity. The remaining small particle pollutants enter the secondary device - the high-voltage electrostatic field, which consists of two stages: the ionizer. The strong electric field charges the particles and turns them into charged particles. These charged particles are immediately adsorbed by the collection electrode and partially carbonized after reaching the second stage dust collector. At the same time, high-voltage electrostatic fields effectively degrade harmful components, playing a role in disinfection and deodorization. After passing through the filter grille, clean air is discharged outdoors.

Purification principle of oil fume purifier:

The purification principle of oil fume purification equipment is based on the comprehensive principles and technologies of physics, chemistry, electromagnetics, microelectronics, etc. It is a new generation of green and environmentally friendly products manufactured using high-tech science and technology. It can quickly, efficiently, and thoroughly purify oil stains, smoke, dust, impurities, harmful gases, odors, etc. in the air, and release clean gases containing ozone converted into pure oxygen.

1. When the oil fume purifier is in operation, it continuously changes the flow rate and direction of the oil fume under the high-speed rotation centrifugal force of the motor, causing the flowing oil fume to collide, compress and condense on the diamond mesh. The condensed oil fume is in the form of particle oil mist, sprayed into the oil tank, and then flows into the oil storage tank.

2. Oil fume processed by a rotary separation system. Transferred into a high-voltage electrostatic field multipole generator, the ozone generated under extremely high voltage undergoes strong oxidation. At the same time, the positive oil fume and electrostatic cathode collide and catalyze all the oil fume through the principles of pulse, instantaneous absorption and discharge, and corona discharge. After being processed by a step-by-step generator, the carbides in the gas are forced to completely decompose and discharged from the outlet.

Its major technical feature is the ability to meet high emission standards, making it impossible for the naked eye to see oil fumes or smell irritating odors. So as to meet the requirements of oil fume purification in sensitive areas and direct emissions at low and high altitudes. Reliable connection to industrial waste gas: purification of waste gases from industries such as plastics, textiles, and printing.

The essential difference between high-altitude and low-level oil fume purifiers:

There are two types of oil fume purifiers, high altitude and low altitude, depending on whether the smoke pipe reaches the roof. The main difference between the two is the difference in purification effect. The high-altitude purification rate is relatively low, only about 60%, suitable for areas with smoke pipes up to the roof and no complaints from residents. The price is also affordable, reducing costs. Low altitude emissions are suitable for areas without smoke pipes to the rooftop, where the environment is sensitive and there are complaints. The price is more than five times that of high-altitude areas, which increases the cost of complaints for catering owners. You can freely choose according to the conditions of the restaurant.

Purification efficiency

According to their names, we can also conclude that high-altitude exhaust fume purifiers discharge purified fumes into the air, while low-level exhaust fume purifiers directly discharge purified gases into the air. Low altitude emission oil fume purifiers are equivalent to emitting into sensitive areas, so their purification efficiency is much better than that of high-altitude emission oil fume purifiers.

The purification efficiency of general high-altitude exhaust fume purifier equipment can reach 60% -70%, while the purification efficiency of low altitude exhaust fume purifier equipment is over 95%. However, the gases purified by these two types of oil fume purifiers can meet the requirements of the national environmental protection oil fume emission standards.

Secondly, in terms of price

Relatively speaking, low altitude exhaust fume purification equipment has high purification efficiency and good internal material quality, so its price is much higher than that of high-altitude exhaust fume purification equipment.

Thirdly, on the pipeline

The high-altitude exhaust fume purifier equipment requires the purified gas to be sent to high altitude before being discharged, so an oil and smoke pipeline needs to be installed at the outlet of the fume purifier. The low altitude oil fume purifier equipment can directly discharge the purified gas into the atmosphere, so there is no need to make an oil fume pipeline at the outlet.
