Embodiment Construction

[0034] In order to further understand the content, features and effects of the present invention, the following examples are given, and detailed descriptions are given below with reference to the accompanying drawings.

[0035] The inventor has been engaged in the research on the mechanism and diffusion of oil fume. By establishing the mechanism and diffusion model of oil fume, he proposed the theory of effective negative pressure zone of oil fume. Cooking fumes are mainly composed of four states of matter before they are mixed with air: fuel combustion exhaust, food spills, water vapor and oil gasification, and cracking products. Diffusion of temperature difference, diffusion of pressure difference, and diffusion of concentration difference and density difference will also occur. To suppress the diffusion of oil fume, prevent the escape of oil fume, and reduce the mixing of oil fume and air, a strong negative pressure field is required, which is the effective negative pressure...

Abstract

The invention belongs to the technical field of cooling lampblack exhaust and discloses a high-static-pressure cooking lampblack treatment device and a range hood. The high-static-pressure cooking lampblack treatment device comprises a lampblack suction structure, a lampblack grease and particle removal structure, a lampblack exhaust structure and a silencing structure, wherein the lampblack suction structure is composed of a condenser plate, a negative-pressure distribution filter and a lampblack suction fan; the lampblack grease and particle removal structure is composed of the negative-pressure distribution filter; the lampblack exhaust structure is composed of the lampblack suction fan, a static pressure tank, an exhaust pipeline and a check valve; and the silencing structure is composed of the negative-pressure distribution filter, the static pressure tank and a lining sound absorption material. According to the high-static-pressure cooking lampblack treatment device, the static pressure tank is arranged at an air outlet of the lampblack suction fan, the flowing pressure of gas discharged from the lampblack suction fan is further converted into static pressure; under the condition of not increasing the power of the range hood, effective energy of resistance of the exhaust pipeline is overcome to the maximum extent to achieve complete exhaustion of lampblack; meanwhile, through reasonable arrangement of the negative-pressure distribution filter and the lining sound absorption material of the static pressure tank, the high-static-pressure cooking lampblack treatment device achieves the effects of high efficiency, silence and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of cooking smoke removal, and in particular relates to a high static pressure cooking fume treatment device and a range hood. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: Cooking fume from Chinese food is the main factor that pollutes the indoor air of residents, and it is also one of the sources of air pollution. Solving the problem of cooking oil fume pollution is related to home life and health. At present, range hoods and integrated stoves are the main devices for dealing with oil fume. There are three steps in the treatment process, namely, oil suction, oil removal and oil fume exhaust. The oil suction is generated by the negative pressure area of ​​the fan through work to induce oil fume and air to enter the body. Then, the dynamic pressure and static pressure are obtained through the work of the wind wheel, that is, the gas flow ch...
