The present disclosure relates to a lampblack purifier, in particular to an internal circulation type lampblack purifier used indoors.
People expect to breathe fresh air when haze is shaded and viruses are raging. According to scientific analysis, harmful gas emitted by catering (including hotel catering and home catering) is one of important factors influencing atmospheric pollution. In order to control the emission of catering to the atmosphere, although strict regulations and measures are continuously adopted at the policy level, the degree of atmospheric pollution cannot be fundamentally improved due to the insufficiency of technical means.
In order to meet the requirements of public social environment and life of people, a circulation type range hood or an internal circulation type lampblack purifier is provided in the prior art, and lampblack, peculiar smell and harmful gas generated in cooking are directly purified indoors, and clean gas generated after purification returns to the room again and is not discharged to the outside. Internal circulation type lampblack purifiers are already applied in western developed countries, and some countries even adopt legal bans to prohibit direct discharge of catering to the outside. Although many existing patents basically realize pollution-free emission of catering cooking to the outside, a plurality of defects still exist in the purification effect, particularly, although gas is purified in the purification process, the temperature of the discharged gas is high, the gas is not effectively cooled, and when the gas returns to the room again, the rise of indoor temperature and overflow of a large amount of water vapor are caused, so that discomfort of cooking operators is caused and is particularly prominent in hot summer.
Aiming at the defects and disadvantages in the prior art, the present disclosure provides an internal circulation type lampblack purifier which can purify lampblack, peculiar smell and harmful gas generated by catering cooking, effectively reduce the temperature of exhausted gas and eliminate the influence of water vapor on the indoor environment.

The concept, specific structure and resulting technical effects of the present disclosure will be further described below in conjunction with the attached figures so as to fully understand the objects, features and effects of the present disclosure.
The present disclosure is further described below in combination with the attached figures.
As shown in
The mechanical grease separator 7 is of a double-layer concave-convex oppositely buckled grease separation screen plate structure or a motor-driven radiation type centrifugal screen disc structure. It is worthy remembering that the two structures can be independently used, and can also be used at the same time. The function of the mechanical grease separator 7 is that when mixed gas such as lampblack, peculiar smell and harmful gas generated in cooking is sucked and discharged by the fan device 6, grease and other gases in the mixed gas are effectively separated through the mechanical grease separator 7, the separated grease is collected through flow guiding, and other gases enter the air outlet channel 5 through the fan device 6, so that grease in the mixed gas is effectively separated from the other gases. Preferably, when the mechanical grease separator 7 is of a grease separation screen plate structure, the mechanical grease separator 7 is arranged at the air inlet 2, so that the mechanical grease separator 7 not only realizes the separation of grease from other gases, but also can effectively intercept impurities entering the air inlet channel, and flames of the cooking bench can be prevented from entering the air inlet channel 4; when the mechanical grease separator 7 is of a radiation type mesh disc structure, the mechanical grease separator 7 is arranged in the air inlet channel 4 and is combined with the fan device 6, namely, the mechanical grease separator 7 and a fan driving motor of the fan device 6 are concentric and coaxial, and under the driving of the fan driving motor, high-speed rotation is realized to separate grease from other gases.
The gas purification device 8 is one or different combinations of more than two of an electrostatic lampblack purifier, an HEPA (High Efficiency Particulate Air) high-efficiency filter screen, an activated carbon filter screen, a TiO2 photocatalyst filter screen and an ultraviolet lamp (UV lamp tube). Under the suction action of the fan device 6, mixed gas enters the gas purification device 8, the gas purification device 8 purifies smoke, peculiar smell and harmful gas (including smoke particles, germs and viruses, VOCs and the like) in the mixed gas, and the treated clean gas enters the cooling device 9 under the action of the fan device 6. The gas purification device 8 can be arranged at the air outlet 3 or in the air outlet channel 5, or can be arranged in the air inlet channel 4, but preferably the gas purification device 8 is arranged at the air outlet 3 or in the air outlet channel 5. The gas purification device 8 has the advantage that a trace amount of grease remaining in the mixed gas subjected to grease separation is purified more deeply through high-speed centrifugal rotation of a centrifugal fan of the fan device 6, so that no grease exists in the mixed gas entering the air purification device 8, and the purification effect of the gas purification device is prevented from being affected and polluted.
As shown in
As an optional embodiment, the cooling device 9 further comprises a water storage tank and a water pump, and the water supply pipe 91 is connected with the water storage tank. The water pump pumps water in the water storage tank to supply the water to the water supply pipe 91, ice blocks can be placed in the water storage tank to reduce the water temperature in stuffy summer, and therefore the cooling effect of the cooling device 9 is improved. It is worthy remembering that the water storage tank and the water receiving tank 95 are combined into a whole, namely the water storage tank is the water receiving tank 95, so that the cooling device 9 can form an internal water circulation system, water recycling is facilitated, and due to the fact that part of water is lost in the using process, water only needs to be injected into the water storage tank (the water receiving tank 95) irregularly.
The cooling device 9 further comprises a drainage pipe 96, one end of the drainage pipe 96 communicates with the water receiving tank 95, and the other end of the drainage pipe 96 communicates with the outside of the internal circulation type lampblack purifier, and the drainage pipe 96 is used for discharging the water inside the water receiving tank 95.
When the spray nozzles 941 spray water (the temperature of the sprayed water is usually between 15° C. and 20° C.), the water spray guide plate 92 can form water curtains, so that the temperature of purified gas (the temperature of the purified gas is usually far higher than the indoor temperature and the purified gas contains high-temperature water vapor) is greatly reduced after passing through the water spray guide plates 92, and the influence of the high-temperature water vapor on the indoor environment is avoided, so that the finally discharged gas does not have obvious influence on the indoor temperature, meanwhile, high-temperature water vapor in the gas is eliminated, and the discomfort of indoor personnel is eliminated.
Preferred embodiments of the present disclosure have been described in detail above. It should be understood that numerous modifications and variations can be made by those skilled in the art without creative work in view of the inventive concept. Therefore, a technical solution which can be obtained by those skilled in the art by logistic analysis, reasoning or limited experimentation on the basis of the prior art according to the idea of the present disclosure is intended to be within the scope of protection determined by the claims.
