Description

A cooking oil fume purification equipment

technical field

The utility model relates to the technical field of kitchen oil fume purification, in particular to a kitchen oil fume purification equipment.

Background technique

Whether it is a large hotel, a canteen, or a family kitchen, most of the oily fume generated during food cooking is directly discharged into the air through the range hood, and the oily fume particles are suspended in the low-altitude air, which pollutes the low-altitude air to a certain extent. Industrial waste gas , motor vehicle exhaust and cooking fumes from the catering industry are regarded as the three "killers" that cause urban air pollution. Oil fume suspended particles are easy to condense bacteria in the air, inhaled into the human body, and easily adsorbed on the respiratory tract to cause respiratory tract infection, which poses a serious threat to people's health.

The range hoods currently used are almost all simple to move the fume from the kitchen to the outside of the kitchen, without any purification process, and can only solve the problem of indoor air. Although some large hotels and canteens use chimneys to discharge oil fumes to high altitudes in order to avoid the impact of oil fumes on the surrounding residents, it is very easy to condense oil fumes in the chimneys and breed bacteria. causing serious disturbance to residents. In addition, cooking fume is usually fine suspended particles mixed with cooking oil vapor and soot, which is easy to condense water vapor. Using water mist can effectively absorb harmful substances in cooking fume.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to Fig. 1, Fig. 2 and Fig. 3, a cooking oil fume purification equipment includes an oil purification host 6, the inlet of the oil purification main unit 6 is connected to the oil fume collection cover 2 through the first smoke guide pipe 3, and the oil fume collection cover 2 Collect the cooking fume from stove 1;

The inlet of the oil purification host 6 is connected with a second smoke guide pipe 5, one end of the smoke guide pipe 5 is designed with a connecting flange 4, and the other end is connected with the oil fume purification host 6, and the connecting flange 4 is used to connect the first guide pipe. The smoke pipe 3 and the second smoke guide pipe 5 are used to introduce the oil fume into the oil fume purification host 6;

The interior of the oil fume purification main unit 6 is divided into upper and lower layers by a liquid return plate 19. The upper layer is provided with an oil fume partition 14 and a dryer 16. The oil fume partition 14 is fixed on the oil fume purification main unit 6 and the liquid return plate 19 at intervals. The oil fume partition 14 An atomizing nozzle 15 is installed on the top of the oil fume purification main unit 6 in the middle, and an induced draft fan 7 is installed on the top of the dryer 16. The oil fume partition 14 is used to separate the oil fume channel from the upper space of the oil fume purification equipment main unit 6, and the atomizing nozzle 15 is used for spraying. The atomized cooling water is discharged, and the oily fume meets the atomized cooling water in the oily fume passage, condenses into small water droplets and falls to the liquid return plate 19, forming a mixed liquid of oil, water and smoke, and then flows back to the oil through the liquid return plate 19 Separation pool 18, dryer 16 are used to dry and purify the air, and induced draft fan 7 is used to provide power for the flow of soot; the lower layer is provided with oil separation pool 18 and oil collection pool 17, since the density of oil is less than that of cooling water After the oil enters the oil separation tank 18, the oil is automatically separated from the mixed liquid and floats on the surface of the cooling water. The oil collection tank 17 is used to collect the oil 20; the oil separation tank 18 is provided with a slow flow partition 21. The side wall of the oil separation tank 18 is provided with a water injection port 24 and a water outlet 23, the water outlet 23 is provided with a water outlet valve 22, the water injection port 24 is provided with a water injection valve 9, and the front wall of the oil separation tank 18 is provided with a liquid level The display 13, the bottom of the oil collection tank 17 is connected to the oil guide pipe 10, the oil guide pipe 10 is equipped with an oil pipe valve 11, and the slow flow partition 21 divides the oil liquid separation tank 18 into a liquid flow channel, so as to reduce the amount of liquid in the oil liquid separation tank 18. The flow rate is better to achieve the purpose of separating the oil liquid 20. The water injection port 24 is used to add cooling water to the oil fume purification host 6, the water injection valve 9 is used to control the addition of cooling water, and the water outlet 22 is used to replace the cooling water. The cooling water in the oil fume purification host 6 is released, the water outlet valve 22 is used to control the oil fume purification host 6 to release cooling water, the liquid level indicator 13 is used to observe the height of the cooling water and oil in the oil fume purification host 6, and the oil guide pipe 10 is used to discharge the cooling water from the oil fume purification host 6. The oil in the oil collection pool 17 is released, and the oil pipe valve 11 is used to control the on-off of the oil guide pipe 10 .

The side wall of the oil purification main engine 6 is equipped with a water circulation pump 12, the inlet of the water circulation pump 12 is connected to the bottom of the oil separation pool 18 through the water pipe 8, the outlet of the water circulation pump 12 is connected to the atomizing nozzle 15 through the water pipe 8, and the water circulation pump 12 is used In order to provide water pressure for the water circulation circuit, the coolant in the oil-liquid separation pool 18 is extracted, introduced into the atomizing nozzle 15 through the water pipe 8, and finally sprayed out from the atomizing nozzle 15.

There is a gap of 3mm between the bottom of the oil fume partition 14 and the liquid return plate 19, which facilitates the flow of the mixed liquid back into the oil-liquid separation pool 18, and prevents the oil fume from flowing through the gap, reducing the efficiency of oil fume purification.

The liquid return plate 19 is designed to have an inclination angle with the horizontal plane, so as to facilitate the mixed liquid to flow back to the oil-liquid separation tank 18 .

The slow flow partitions 21 are arranged alternately at the bottom of the oil separation pool 18 to prolong the flow path of the mixed liquid in the oil separation pool 18 and improve the separation effect of the oil liquid 20 .

The working principle of the utility model is:

During use, connect the water injection port 24 to the tap water pipe, open the water injection valve 9, add cooling water to the oil fume purification host 6, observe the liquid level indicator 13 at the same time, and close the water injection valve 9 when the water level reaches the scale line requirement. When the stove 1 starts cooking, turn on the switch of the induced draft fan 7 and the water circulation pump 12 of the oil fume purification host 6, and the mixed gas of the oil fume and air generated by cooking flows into the first smoke guide pipe 3 from the oil fume collecting cover 2, and then passes through the second The smoke guide pipe 5 enters the oil fume evolution host 6, and the oil fume flows along the oil fume partition 14 in the oil fume evolution host 6 to form an oil fume channel. The particles are absorbed by the atomized droplets and fall onto the liquid return plate 19 to form an oil-water mixture and flow back to the oil-liquid separation tank 18 . The purified air is finally discharged from the induced draft fan 7 through the dryer 16 . In the oil-liquid separation pool 18, due to the action of the slow-flow partition 21, the flow velocity of the mixed liquid decreases, the oil is insoluble in water, and the density of the oil is less than that of water, the oil in the mixed liquid gradually precipitates and floats on the water surface , finally flows into the oil sump 17. After cooking finishes, open oil pipe valve 11, the oily liquid in the oil sump 17 is released. Simultaneously, after observing that the cooling water becomes turbid from the liquid level indicator 13, the cooling water in the oil fume purification main unit 6 is discharged through the water outlet 23, and clean cooling water is re-added.
