Cooking fume purifying device

Abstract

The invention relates to a cooking fume purifying device. The cooking fume purifying device comprises an air pipe for cooking fume to pass through, wherein a plurality of oil-removing liners are arranged in the air pipe in the cooking fume flowing direction, and each oil-removing inner liner comprises a plurality of glass fiber cotton pipes which are mutually parallel and stacked. Compared with the prior art, the device has the beneficial effects that commercial conventional glass fiber cotton pipes are used for cooking fume purification for the first time, the oil removal efficiency is high,the oil removal effect is good, oil can be removed by physical adsorption desorption, and the oil can be directly and effectively recovered; the glass fiber cotton pipes can be reused, the service life is long, and the cost is greatly reduced; the adsorption effect is good, and the glass fiber cotton pipes can effectively absorb sound and reduce noise and are flame retardant and fireproof in the oil removal process, so that the problems of high wind noise, fire risk due to more oil mist at high temperature and the like of existing range hoods are solved.

Description

technical field [0001] The invention belongs to the technical field of oil fume purification, and in particular relates to an oil fume purification device. Background technique [0002] With the continuous improvement of environmental protection standards and the continuous strengthening of people's attention to physical health, the method of directly discharging the flue gas with oil mist into the atmosphere is increasingly restricted and tired of by the environmental protection department and the majority of residents. In view of this situation, people have developed a range hood with oil fume separation function, as Chinese patent (patent No. is: 99233766.6) discloses a kind of " range hood ", and it is remanufactured by exhaust fan, comprises housing, fixed The motor and the impeller are installed on the casing, the rear side of the casing is closed, an exhaust port is opened on the peripheral wall of the casing, the air guide pipe is matched with the exhaust port, and a...

In view of this situation, people have developed a range hood with oil fume separation function, as Chinese patent (patent No. is: 99233766.6) discloses a kind of " range hood ", and it is remanufactured by exhaust fan, comprises housing, fixed The motor and the impeller are installed on the casing, the rear side of the casing is closed, an exhaust port is opened on the peripheral wall of the casing, the air guide pipe is matched with the exhaust port, and a water tank is arranged under the air guide pipe, and the water tank contains If there is water or alkali solution, the lower end of the air guide tube is inserted into the solution, so that the oily fume is discharged after the solution is filtered and purified. It does not pollute the air, has a simple structure and low cost, but it needs to install a water tank, and at the same time, people need to monitor the water in the tank. Inconvenient to use, and noise will be generated when oil fume passes through the solution, which will affect people's normal life

Another example is the Chinese patent (patent number: 9923200.3) which discloses a "range hood flue gas purification device", which contains filtrate in the cylinder body, and is equipped with an air inlet pipe, and one end of the air inlet pipe is inserted in the filtrate, The other end is the connecting end of the exhaust pipe of the range hood. A baffle plate and a sieve plate are fixed in the cylinder body. A gas filter is installed on the sieve plate. The cylinder cover is covered on the cylinder body. The position of the hole is connected with an exhaust pipe, and a three-way pipe is installed at the bottom of the cylinder, and a liquid level observation tube and a sewage valve are installed on the three-way pipe, which can reduce or prevent the pollution of the oil fume to the environment through the filtration of the filtrate and the filter. Pollution, but it also requires people to monitor the water volume in the tank, causing inconvenient use, high energy consumption, waste of water, and high cost

Another example is that the Chinese patent (patent No. is: 02221725.8) discloses a "oil fume filter". The cross-section is a trapezoidal strip hole, and the oil fume inlet and outlet are staggered. The filter forms several channels that make the oil fume flow suddenly turn, which is more conducive to the separation of oil fume, but it increases the noise at the same time, and implements single-stage filtration. limited effect
