Environment-friendly oil fume deep purifier

Abstract

The invention discloses an environment-friendly oil fume deep purifier. The environment-friendly oil fume deep purifier has the advantages that under the synergy action of cooling, centrifugal oil removing, ultraviolet, nano titanium dioxide photocatalyst and activated carbon fibers, trace greasy dirt, harmful gas and odors of oil fumes can be thoroughly removed, bacteria and viruses can be killed, gas after deep purification can be directly discharged in a room, inner circulation is achieved, zero outward emission is achieved, clean indoor air is achieved, and indoor and outdoor environmental protection are achieved; the purifier is matched with one kitchen range, a pipeline and a chimney are omitted, oil adhesion in the purifier is avoided, and the purifier is free of space occupation, convenient to mount, use and maintain, good in safety and economy, power saving, widely applicable to oil removing of large, medium and small restaurants, family kitchen range hoods and industrial production, and the like; if the purifier is popularized, residence without the oil fumes, communities without the oil fumes and even cities without the oil fumes can be achieved, great contribution is made to atmosphere PM2.5 pollution treatment, and city appearance neatness is achieved due to the fact that the chimney is omitted.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an environment-friendly oil fume deep purifier that can be used in catering industry, household and industrial production. Background technique [0002] my country's cooking habits are mainly frying, frying, and deep-frying, and a large amount of oil fumes are generated. Some reports point out that kitchen oil fumes are the main culprit in the source of air pollution, accounting for more than 1 / 4 of PM2.5. Moreover, the composition of oil fume is extremely complex, containing hundreds of pollutants, including strong carcinogens such as volatile nitrosamines and heterocyclic amines, so it is urgent to control oil fume pollution. [0003] At present, there are many ways to control oil fume in the catering industry, but there are many problems in actual use. For example, the more common use is high-voltage electrostatic degreasing, which has the following defects: [0004] ...

AI Technical Summary

Problems solved by technology

[0006] 1. The oily fume from each stove is discharged into the main pipe. The main pipe is very easy to accumulate oil, and it is very difficult to clean it, which brings potential safety hazards. Fires often occur in restaurants at home and abroad due to oil accumulation in the pipes;

[0007] 2. High-power fans are used for centralized management. No matter how many stoves are used, even if only one fan is turned on, the fans must be turned on, which is a serious waste of electricity;

[0008] 3. In the early stage of use, the oil removal efficiency is about 90%, but it cannot remove gaseous pollutants and odors, and there is still a large pollution to the environment. After a period of use, the electrode plate will stick to oil, and the oil removal effect will drop sharply. If it is not timely Cleaning up will cause short circuit of the electrodes, the efficiency will be reduced to zero, and there is a danger of fire. Electrode cleaning is very troublesome and requires high technical requirements. Many users are afraid of trouble, thinking that the installation of facilities is deemed to be up to standard, and secretly shut down the facilities, resulting in high oil fumes. Concentration emission, due to the large number of users, it is very difficult for the regulatory authorities to supervise

[0010] 1. When working, the room is in a negative pressure state, and the doors and windows must be opened to work normally. The oily smoke is easy to disperse, which affects the cleaning effect. When there is wind, sand, smog, extreme cold, and high humidity, users often close the windows, resulting in indoor negative pressure. If the pressure increases, the effect of oil suction will be greatly reduced, and the lack of oxygen will affect the combustion of the stove, and because of the negative pressure, the dirty gas in the floor drain and the sink will be sucked to the stove surface, which is extremely unhygienic;

[0011] 2. When using it, it is necessary to connect the pipeline system composed of check valve, pipe, elbow and chimney. Only 5 cubic meters per minute, which seriously affects the suction effect, wastes electricity and increases noise;

[0012] 3. The oil fume is directly discharged through the wall, sometimes it will blow the wind and smoke, and it will also cause pollution to the neighbors. If it is connected to a public flue, not only will the resistance be greater, but there will be gas, odor, and cross-contamination between users. A large amount of oil accumulation will breed bacteria, pests, and fire risks;

[0013] 4. After using for a period of time, the inside of the fan, the motor, and the pipes will be sticky with oil, which will breed bacteria and produce odors, produce vibrations, affect the suction, and it is very troublesome to clean, which will also affect the service life of the machine;

[0014] 5. A large amount of gas is discharged outside, which will also cause a large loss of cooling (heat) capacity of the indoor air conditioner, which seriously affects building energy saving

[0016] At present, a domestic purification network disk that relies on high-speed rotating centrifugal force to remove oil has been used on range hoods. The oil removal efficiency can reach more than 95%, which can greatly reduce the pollution of oil fume to the atmospheric environment, but it still cannot overcome the above problems. There are most of the defects in the technology, and: first, although it can remove oil well, it cannot remove gaseous pollutants and odors, and the purification is not thorough; second, when it is used in the catering industry, because the oil pan often catches fire when cooking, centrifugal purification network The disk bears the brunt, the motor and wire are exposed to open fire and high temperature, which is very unsafe; third, the existing structure and production method of the centrifugal purification network disk are not reasonable, and the fine mesh wire is wound by winding or hundreds of points of welding are used in the production. It is more troublesome and difficult to guarantee quality, which is not conducive to mass production
