Description

Particle collision type flue gas treatment device Technical Field The invention relates to the technical field of oil fume purification, in particular to a particle collision type fume treatment device. Background The oil fume has complex components, and mainly comprises grease particles, volatile organic compounds, water vapor and a small amount of solid particles. These components are produced during high temperature cooking and if discharged directly without treatment, can lead to air pollution, oil accumulation in the pipes and even fire hazards. At present, people separate, filter or convert pollutants such as oil smoke, particulate matters, smell and the like generated in the cooking process through an oil smoke purifier to reach the national emission standard, so that the pollution to the environment is reduced, and meanwhile, the health of kitchen workers is protected. The traditional oil smoke purifier is mainly a mechanical oil smoke purifier, particles in oil smoke are removed mainly through a metal filter screen in a physical filtration mode, the removal effect on fine particles and gaseous pollutants is limited, the purification efficiency and effect are poor, and the oil smoke purifier is only suitable for small-sized catering places or families and is difficult to meet the purification requirements of places such as Chinese restaurants, barbecue shops, hotels or school canteens for producing a large amount of oil smoke. Therefore, based on the physical phenomenon that the gas is liquefied when encountering cold, various refrigeration type oil fume purifiers appear, and oil-water gas in the oil fume is liquefied and removed in a condensing mode, so that the oil fume purifying effect is realized. For example, in the prior application of the applicant, the application number is CN202421751266.5, and in the range hood, by arranging the condensation component in the range hood channel, the range hood contacts the condensation component under the action of the fan, and the liquefaction condensation phenomenon occurs, so that oil molecules and water molecules in the range hood are removed in the form of liquid drops. However, in order to achieve the purpose of condensation, the oil smoke needs to directly contact the surface of the condensation component, on one hand, the projection of the upper opening and the lower opening of the oil smoke channel in the prior application is overlapped, namely, the oil smoke channel is vertical, the residence time of the oil smoke in the oil smoke channel is short, the time of the oil smoke contacting the surface of the condensation component is short, and the oil smoke is difficult to be effectively cooled by the condensation component, on the other hand, the condensation component is in a contact condensation mode, so that most of oil water molecules are condensed and liquefied, and then drop under the action of gravity, but part of oil dirt still adheres to the condensation component, so that the oil smoke is difficult to contact the condensation component in use, the effect of condensation and degreasing is greatly reduced, and although the spraying component is arranged on the upper side of the condensation component in order to regularly remove the adhered oil dirt on the condensation component, the viscosity of the oil smoke is high, the oil dirt is difficult to be removed by simple spraying, and especially the condensation component adopts the design of a fin group with a wavy section, the structure shape, and the difficulty of removing the oil dirt is further increased. How to solve the problems is a technical problem to be solved. Disclosure of Invention The invention aims to provide a particle collision type smoke treatment device which has less greasy dirt adhesion and low cleaning difficulty, can effectively prolong the retention time of the lampblack and effectively improve the purifying effect. In order to achieve the above purpose, the invention adopts the following technical scheme: The invention provides a particle collision type flue gas treatment device which comprises a shell, wherein at least two layers of chambers are formed in the shell by separation of a baffle plate, a flue gas inlet used for being communicated with a chamber at the bottommost layer is formed in the bottom of the shell, a flue gas outlet used for being communicated with a chamber at the topmost layer is formed in the top of the shell, two adjacent chambers are communicated through the flue gas outlet, the projection position of at least one flue gas outlet is not overlapped with the flue gas inlet and/or the flue gas outlet to form a bent flue gas channel, at least one cold ion emission module used for emitting low-temperature fluid is arranged in the flue gas channel, and the emission direction of the cold ion emission module is at least partially opposite to the flow direction of flue gas. As a preferred embodiment, the number of the chambers is two, including a lower c
