Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, embodiments of the present utility model will be described in detail hereinafter with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be arbitrarily combined with each other. In the embodiments of the present utility model, the use environment of kitchen fume is taken as an example, and those skilled in the art will recognize that the fume purification system claimed in the present utility model can be used in all other available environments except the kitchen. The technical term "soot" of the present utility model is not limited to soot generated in a kitchen, but refers to various industrial and domestic waste gases containing smoke and harmful substances.

As shown in fig. 1, there is shown a fume purification system usable in a kitchen environment, comprising a collection hood 1, a guide pipe 2, a purification assembly and a heat dissipation assembly, wherein the collection hood 1 is connected with the purification assembly through the guide pipe 2, the purification assembly is communicated with the heat dissipation assembly through a water pipe 7, a first heat exchanger 33 and a spraying device 34 are arranged in the purification assembly, a second heat exchanger 41 is arranged in the heat dissipation assembly, and the first heat exchanger 33 and the second heat exchanger 41 are communicated through a circulating pump 43. According to the utility model, the oil smoke in the purification assembly is sprayed through the spraying equipment, and meanwhile, the heat contained in the waste gas is exchanged into the spraying water of the heat dissipation assembly through the heat exchanger, so that the temperature of the spraying water is increased, and more pollutants in the oil smoke can be cleaned. The utility model can not only clean the pollutant in the oil smoke with high efficiency, but also can use the heat contained in the waste gas to increase the temperature of the spray water, thereby improving the cleaning efficiency.

Specifically, as shown in fig. 1, the purification assembly includes an exhaust passage 31, a first heat exchanger 33, a spray device 34, and a sewage collector 35, and a fan 32 is provided at an end of the exhaust passage 31. The first heat exchanger 33 and the shower device 34 are disposed in the exhaust passage 31, and the sewage collector 35 is disposed at a lower portion of the exhaust passage 31. The heat dissipation assembly comprises a water tank 40, a second heat exchanger 41 and a circulating pump 43, wherein the second heat exchanger 41 is arranged in water in the water tank. The shower device 34 communicates with a water tank in the radiator assembly through a water pipe 7. The second heat exchanger 41, the circulating pump 43 and the first heat exchanger 33 form a circulating heat exchange system, namely, a heat exchange medium obtains heat in the first heat exchanger 33 and exchanges heat with the second heat exchanger 41 in the water tank, so that the spray water temperature in the water tank is increased, and the spray effect is improved. At the same time, the temperature of the heat exchange medium is reduced, and the oil smoke is easier to condense by entering the first heat exchanger 33 again. An electric heater 45 can be arranged in the water tank, and when the water in the water tank cannot be heated to the required temperature for spraying by the heat extracted from the lampblack, the water can be heated to the required temperature by the electric heater 45.

Preferably, the collection hood 1 can be fixed to the partition 5 and mounted above the cooktop 6. The collecting cover 1 can be hung and fixed on the isolating body 5, and can also be pivoted with the isolating body by adopting a hinge, so that the collecting cover can be folded when the kitchen range does not work, and the occupation of the collecting cover to the space is reduced. The spacer 5 of the present utility model may be a rigid structure having a certain strength, such as a wall. The isolator can effectively isolate the space where the purification assembly and the kitchen range are located, so that the influence of the noise of the smoke exhaust fan on cooking staff at the kitchen range can be reduced, and the dissipation of oil smoke in the cooking space can be reduced, thereby improving the user experience.

One end of the guiding pipe 2 is communicated with the collecting cover 1, and the other end is communicated with the purifying component. As shown in fig. 1, the guide pipe 2 may be extended directly through the separator 5 to introduce the soot collected in the collection hood 1 into the exhaust passage of the purification assembly. The guide tube 2 is preferably placed obliquely, i.e. with its inlet end arranged higher than its outlet end. Thus, even if the fume is condensed in the guide pipe, the fume can automatically fall into the purifying component. The purification assembly is separated from the working space by the separator 5, and is connected with the heat dissipation assembly by the water pipe 7, so that hot water introduced into the heat dissipation assembly sprays and cleans waste gas and the first heat exchanger 33 in the purification assembly, and flushing sewage is connected with a user sewage pipeline by the sewage collector 35 at the lower part of the purification assembly. After being purified by the purifying component, the temperature of the oil fume is reduced and becomes clean.

Preferably, as shown in FIG. 1, a blower 32 is disposed at the end of the decontamination assembly to help keep the blower clean. The first heat exchanger 33 is internally provided with a heat exchange medium for circulating heat exchange, and the temperature of the heat exchange medium is lower than the condensation temperature of most components in the lampblack. The oil smoke is heat-exchanged with the first heat exchanger 33 while flowing in the exhaust passage 31, and the temperature of the oil smoke is reduced to be condensed. The first heat exchanger 33 may employ a small-passage tube type heat exchanger to increase the heat exchange area. The arrangement of the first heat exchanger 33 can on the one hand make the condensed tobacco tar easy to drip along the heat exchange tube and on the other hand can also facilitate flushing clean during spraying. The spray equipment 34 preferably adopts an intermittent spray mode to ensure the cleaning on the first heat exchanger 33. In order to better improve the spraying oil removal effect, a water pump can be additionally arranged on the water pipe 7 between the spraying equipment 34 and the water tank 40 to increase the spraying pressure, so that a better spraying effect is realized. The sewage collector 35 receives the tobacco tar condensed and dropped on the first heat exchanger 33 and sewage generated during the intermittent spraying. The sprayed sewage can simultaneously wash the tobacco tar which is already received on the sewage collector 35, and finally is discharged into the sewage pipeline.

Preferably, the heat dissipating assembly may further include an auxiliary heat sink 42 and a switching valve 44, the switching valve 44 being disposed between the first heat exchanger 33 and the second heat exchanger 41, the auxiliary heat sink 42 being connected to the switching valve 44, the auxiliary heat sink 42 being disposed in parallel with the second heat exchanger 41. When the temperature of the water in the water tank rises to a certain extent, so that the temperature of the heat exchange medium rises and the oil smoke cannot be effectively condensed and purified on the first heat exchanger 33, the heat exchange medium can be switched to the auxiliary radiator 42 through the switching valve 44. At this time, the auxiliary radiator 42, the switching valve 44, the circulation pump 43, and the first heat exchanger 33 constitute another circulation heat exchange system. A cooling fan may be provided on the auxiliary radiator 42, and the auxiliary heat exchanger 42 may lower the heat exchange medium to a desired temperature using cold air generated by the cooling fan. In addition, when the heat generated by the kitchen range 6 is large enough, a branch can be led out from the heat radiating component, and the hot water can be used for other purposes.

Although the embodiments of the present utility model are described above, the embodiments are only used for facilitating understanding of the present utility model, and are not intended to limit the present utility model. Any person skilled in the art can make any modification and variation in form and detail without departing from the spirit and scope of the present disclosure, but the scope of the present disclosure is still subject to the scope of the appended claims.
