technical field

The invention relates to a composite high-efficiency oil fume purification equipment.

Background technique

In recent years, the problem of air pollution has become increasingly serious, and smog has become more and more frequent in large and medium-sized cities. Among all the many factors that cause air pollution, a large amount of cooking fume produced by the catering industry not only seriously pollutes the environment, but also poses a great threat to people's lives and health. At present, the oil fume purification equipment commonly used at home and abroad mainly includes electrostatic deposition equipment, filtration equipment, wet washing equipment and inertial separation equipment. These purification equipment, or the rationality of the equipment design needs to be improved, or because the purification efficiency is not high, or due to factors such as high price, high operating cost, difficult maintenance, and excessive floor area, the problem of oil fume pollution in the urban catering industry has been solved for a long time. Nice work out. Therefore, it is of great significance to optimize the design of the traditional compound oil fume purifier, improve its purification efficiency, and make it easy to operate and maintain, compact in structure and small in floor space.

Contents of the invention

Aiming at the deficiencies of the prior art, the present invention provides a compound high-efficiency oil fume purification device with high efficiency in capturing and cleaning the oil fume.

In order to achieve the above object, the present invention provides a compound high-efficiency oil fume purification equipment, which includes a purification pipeline and an oil-water separation tank. The upper port of the purification pipeline is connected with an oil fume absorption pipeline, and a spray device is arranged in the purification pipeline And the purification device, the spray device is located above the purification device, the purification device includes a diagonal flow fan and a rotary filter element, the diagonal flow fan includes a motor and an impeller, the impeller includes a front disc, a rear disc and blades, and a front disc and a rear disc. A tapered passage is formed between the disks, the blades are located in the tapered passage, and are fixed with the front and rear disks, the rear disk is linked with the motor through the transmission device, and the rotating filter element has an inverted conical structure with a wide top and a narrow bottom. The large-diameter end of the rotary filter element is fixed on the front plate, the small-diameter end of the rotary filter element is fixed on the rear plate, and the rotary filter element is located at the entrance of the tapered channel, and the exit of the tapered channel is connected to the There is a dehydrator, and the dehydrator includes a shell and an inner cavity, and a flue gas channel is formed in the inner cavity, and the slit between the outer shell and the inner cavity forms a water flow channel, and the oil-water separation tank includes a box body and a downpipe , a shunt pipe is placed in the box, the upper end of the downpipe is connected with the bottom surface of the water flow channel, the lower end of the downpipe penetrates into the box and is connected with the shunt pipe, the top of the box is provided with an oil collecting port, and surrounds the oil collecting port There is a circle of upwardly protruding coaming plate at the mouth, and an overflow pipe is pierced on the side of the box, and the inner end port of the overflow pipe is bent upwards and extends into the oil collection port, and the inner end port of the overflow pipe is higher than The oil collection port is lower than the upper end surface of the coaming plate, and the outer end port of the overflow pipe is connected with an oil dirt collector. There are also several oblique deflectors arranged in the box, and a storage tank is formed separately in the box. The water tank, and the water storage tank and the shunt pipe are respectively located on both sides of the deflector, the water inlet of the water storage tank is provided with a water inlet filter, the water storage tank is also equipped with an automatic water replenisher, the water storage tank and the spray The devices are connected by an upper water pipe, and a water pump is installed on the upper water pipe.

The beneficial effects of the present invention are: adopting the above-mentioned structure, the oil fume first enters the purification pipe through the oil fume absorption pipe, and then collides with the water mist sprayed by the spraying device, and the oil fume particles are absorbed and captured to realize the first purification. The remaining oily fume passes through the rotary filter element. Since the rotary filter element rotates at high speed driven by the motor, it will form a high-speed cutting and finally filter the incoming oily fume particles, thereby forming a second purification of the oily fume. The filtered mixed air flow will be in a diagonal flow The inside of the fan impeller is in a spiral motion. Because the airflow is in a strong turbulent state at this time, the oil fume and water mist will collide strongly and be purified for the third time. Finally, the purified flue gas will be sucked into the inner chamber of the dehydrator for discharge, while the water vapor containing soot particles will be thrown into the slit between the shell and the inner chamber of the dehydrator under the action of centrifugal force, and along the The water flow channel flows out, thereby realizing the separation of water and air. Afterwards, the water vapor containing soot particles flowing out of the water flow channel passes through the downpipe, and flows into the box under the homogenization of the shunt pipe. Since the density of oil is lower than that of water, the oil will float on the surface of the water. At the same time, under the action of the deflector in the box, the oil and water will be separated better. As the liquid level continues to rise, the oil floating on it will Collected at the oil collection port, when overflowing the inner end port of the overflow pipe, the overflow will be collected along the overflow pipe into the oil dirt collector. The remaining water flows into the water storage tank, is pumped by the water pump, and then supplied to the spraying device, so that it can be circulated for the smoke purification of the compound high-efficiency oil fume purification equipment. In addition, when the water storage in the water storage tank is insufficient, automatic water replenishment can be realized through the automatic water replenisher. Also, when the work is over, the water pump stops pumping water, and the remaining water vapor will continue to flow down into the tank to raise the liquid level. When it overflows the inner port of the overflow pipe, it will overflow and discharge along the overflow pipe. .

The present invention can be further configured such that the spraying device includes a spraying main pipe, the spraying main pipe is coaxially located directly above the rotating filter element, and a number of radially outward and axially upward jets are evenly distributed on the outer circumference of the spraying main pipe. The nozzle is equipped with a solid cone nozzle at the axial lower end of the injection main pipe.

Through the above setting, the spray device can spray a three-dimensional, high-density cross mist net, thereby improving the ability of the water mist to capture oil fume.

In the present invention, it can be further configured that a pressure relief port communicated between the shell and the inner chamber of the dehydrator is provided, and a shielding lip is provided above the pressure relief port.

Through the above arrangement, the opening of the pressure relief port can keep the outer shell and the inner cavity of the dehydrator in the same negative pressure state, so that the oil and water can flow out in time.

In the present invention, it can be further configured that the box body is further provided with a drainage port near its bottom surface.

Through the above arrangement, the water outlet is opened, which can facilitate people to discharge the sewage deposited in the box.
