DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1-5, the present utility model provides a technical solution: an oil fume waste heat recovery device, which includes an upper bracket 81 and a lower bracket 82. The upper bracket 81 and the lower bracket 82 are fixedly connected to each other by welding. One end of the upper bracket 81 is installed with a mechanical primary centrifuge 1. Inside the upper bracket 81, two oil fume purifiers 2 are installed and the two oil fume purifiers 2 are adjacent to each other. Inside the lower bracket 82, a fan 4 is installed. On one side of the fan 4, an electric heater 5 is arranged. On one side of the electric heater 5, a bag type medium efficiency filter 6 is arranged. On one side of the bag type medium efficiency filter 6, a dust filter 7 is arranged. The mechanical primary centrifuge 1 uses the principle of mechanical centrifugation to remove oil stains. The dust filter 7 uses the method of physical barrier to block the particulate matter in the fresh air, so as to achieve the effect of purifying the air; the electric heater 5 uses the heat generated when an electric current passes through a conductor to heat an object. In order to make the mixed air of fresh air and heated air better achieve the expected effect; the fan 4 sends the mixed air of fresh air and heated air into the room;
[0020] The oil fume purifier 2 adopts the dual functions of mechanical separation and electrostatic purification. The oil fume-containing waste gas is sucked into the pipeline under the action of the fan. First, through the pre-filter, large particles are filtered out. The separated large particle oil droplets flow into the oil tank and are discharged under the action of their own gravity. The remaining fine particle oil mist particles enter the ionization zone. The ionization zone adopts the electrostatic working principle of two-stage high and low voltage separation. The electric field of the first-stage ionization plate makes the fine particle oil mist particles charged and become charged particles. These charged particles are immediately adsorbed and partially carbonized after reaching the dust collection area. At the same time, the ozone excited by the high-voltage electrostatic effectively degrades harmful components, playing the role of disinfection and odor removal. Finally, through the filter grid, clean air is finally discharged;
[0021] A heat exchanger 3 is arranged between the upper bracket 81 and the lower bracket 82 in an interspersed manner. The lower part of the heat exchanger 3 is located between the electric heater 5 and the bag type medium efficiency filter 6. The upper part of the heat exchanger 3 is located on the adjacent side of the oil fume purifier 2. The heat exchanger 3 recovers the heat of the oil fume by means of heat pipe heat recovery or solution heat recovery;
[0022] The bag type medium efficiency filter 6 includes a mounting plate 61. On one side of the mounting plate 61, a motor 66 is installed. The output end of the motor 66 is connected to a winding roller 67 through a coupling. A pulling rope 65 is wound around the winding roller 67. Starting the motor 66 drives the winding roller 67 to rotate, so that the pulling rope 65 completes the retraction and release;
[0023] One end of the pulling rope 65 is connected to a joint 64. On one side of the joint 64, a filter bag 62 is fixedly installed. The dust is filtered through the filter bag 62;
[0024] One side of the filter bag 62 is connected with a movable buckle 69. A connecting column 68 is installed on the mounting plate 61. One side of the connecting column 68 is installed with an elastic pulling belt 63. One end of the elastic pulling belt 63 is connected with the movable buckle 69. During use, the movable buckle 69 is fastened, and the position of the filter bag 62 can be maintained. When cleaning is required, the movable buckle 69 is opened. At this time, the filter bag 62 is pulled and dragged towards the position of the mounting plate 61, which is convenient for collecting and removing dust from the right side;
[0025] The number of the filter bags 62 is configured according to the air volume and size.
