Description

Technical Field

[0001] The utility model relates to the technical field of oil fume purification, in particular to an oil fume purification device. Background Art

[0002] Oil fume is the waste gas generated by the kitchen of a restaurant. It is usually purified by oil fume purification equipment before being discharged outdoors. There are many ways to purify oil fume. The most common way is to use water or other detergents to form a water film and water mist to absorb the oil fume. The oil fume particles come into contact with the water mist and water film sprayed by the nozzle. After mutual inertial collision, retention, diffusion of fine particles and mutual condensation, they flow down with water droplets, thereby separating the oil fume ions from the airflow.

[0003] After searching, the patent application No. 201910478193.4 discloses a fume purification device, including a fume hood, a purification device and an exhaust fan. The fume hood and the exhaust fan are each connected to the purification device through an exhaust pipe. It is characterized in that: the purification device includes a purification tank for containing purification liquid. An air inlet pipe extending upward is provided at the bottom of the purification tank. The pipe mouth of the air inlet pipe is lower than the liquid level in the purification tank. The fume hood is connected to the lower end of the air inlet pipe through the exhaust pipe so that the fume hood is connected to the inside of the purification tank. The exhaust fan is connected to the top of the purification tank through the exhaust pipe. The liquid level in the purification tank is lower than the top of the purification tank. When the fume enters the purification tank from the air inlet pipe, the fume contacts the purification liquid and filters the fume through the purification liquid. The fume contacts the purification liquid more fully, ensuring the effect of fume purification. At the same time, this purification device has a simple structure, does not require the use of complex devices, and does not require additional power to form a water film or water mist, saving energy.

[0004] However, in the above technical solution, since the temperature of the oil smoke is relatively high and it is continuously input into the box, it will heat the liquid inside and accelerate its evaporation, which still consumes a lot of water resources. It is not easy to dissipate the heat of the filtered liquid. In addition, due to the internal liquid isolation, the negative pressure adsorption pressure is large, the working pressure of the exhaust components is relatively large, and the smoke exhaust efficiency is poor.

In this process, the heat dissipation component 6 is connected with the suction component 2, and the auger 7 drives the liquid flow upward so that part of the liquid enters the heat dissipation component 6 to dissipate heat and cool down, and then flows into the air duct 4 again. While achieving circulating heat dissipation, the flowing liquid can accelerate the mixing of flue gas and transport it upward, increasing the filtration efficiency, thereby realizing a more efficient purification and exhaust efficiency of the device, and the internal purified liquid can achieve circulating heat dissipation to reduce consumption, thus saving more water resources.
