Near-suction type smoke purifier

Abstract

The invention discloses a near-suction type smoke purifier, comprising a flat oblong housing, wherein the inner part of the housing is provided with a double scroll casing, two isolated chambers of the double scroll casing share an air outlet at the back of the housing; the two isolated chambers of the double scroll casing are internally and respectively provided with a turbofan with an output shaft in vertical state, the lower end of the output shaft of the turbofan extends outside the double scroll casing and is connected with at least one rotary centrifugal filter screen disk in horizontalstate; a equalizing mesh enclosure is installed outside the rotary centrifugal filter screen disk, the bottom of the housing is provided with an oil guide board and an air inlet, and the lower end ofthe oil guide board is provided with an oil collection box. The smoke purifier has high efficiency of intercepting and collecting oil smoke and can fundamentally avoid the pollution of oil smoke for air as well as internal wall of the housing and external wall of the building, thereby having convenient cleaning, energy-saving and noise reduction, no heat energy and cooking space loss, safe and reliable operation, and long service life. The smoke purifier is applied to being mounted above a hearth at the cantilever platform window of a kitchen.

Description

technical field [0001] The invention relates to equipment for treating oily fume discharged from catering industry or family kitchen, and specifically refers to a near-suction type oily fume purifier which is mainly installed at the platform window of the kitchen. Background technique [0002] With the increasing awareness of environmental protection of the general public, the requirements for themselves and the surrounding environment are getting higher and higher, and the prevention and control of air pollution has become a top priority. Relevant survey data show that among the air pollutants in large and medium-sized cities, the pollution caused by catering industry and household oil fume has exceeded that of automobile exhaust. About 40-50% of the air pollutants are kitchen oil fume pollution. The problem of oil fume pollution has become a The focus of today's environmental protection. [0003] At present, there are various types of devices for kitchen oil fume treatmen...

AI Technical Summary

Problems solved by technology

This type of device can directly exhaust the oily fumes in the room to the outside. Its advantage is that it has a good exhaust effect in the early use, but there are big problems in the subsequent use: first, the straight exhaust fan and Range hoods do not have the effect of intercepting or purifying oil fume. After the oil fume is directly discharged outside, it not only pollutes the air, but also pollutes the facade of the building, seriously affecting the urban environmental sanitation and people's health.

Since the motor and fan of the side-suction range fume purifier are actually installed on the top of the machine casing, there is a considerable distance between its air inlet and the motor and fan blades, and the air inlet is very close to the stove, and the inner wall of the casing often It will be polluted by waste oil, causing a large amount of uneven oil accumulation on the fan impeller, and the fan will lose its dynamic balance, so its suction effect will naturally become worse and worse, and its mechanical noise will also become louder

If things go on like this, the device is easily damaged

[0007] Second, heat energy and cooking space are lost, and there are potential safety hazards

Although this intuitively ensures the cleanliness and beauty of the outer surface of the building, due to the lack of effective purification treatment of oil fumes, the centralized exhaust pipes cannot fundamentally solve the problem, and the pollution caused by high oil fume emissions to the air environment is still serious. Moreover, there are problems such as poor smoke exhaust, backflow of smoke, odor, breeding of mosquitoes and rodents, etc.
