Spray swirl type oil fume removal waste heat recovery device

Abstract

The invention discloses a spray and swirl type oil fume waste heat recovery device, which includes an absorption tower, an exhaust fan, an air inlet pipe, a spray pipe and a heat energy transfer system. Tower, the absorption tower is connected to the exhaust pipe, the spray pipe is located in the air inlet pipe and the sprayed liquid flows to the bottom of the absorption tower; there are 1-10 cyclones in the absorption tower; the bottom of the absorption tower is connected by an overflow pipe Water circulation barrel, the water circulation barrel is equipped with a float valve connected to the water pipe to keep the water level constant, the water in the water circulation barrel is connected to the spray pipe and the top of the absorption tower through the water pump; the hot water tank is connected to the tap water pipe and the valve for hot water output. The invention utilizes water spray swirl circulation to cool and condense the fume steam, and at the same time transfers and utilizes the heat recovered by the water with a heat pump, so that not only the fume is thoroughly removed, but also the waste heat in the fume is fully utilized, which is environmentally friendly, energy-saving and practical strong features.

Description

Technical field [0001] The invention relates to a device for recovering oil and fume waste heat, in particular to a spray swirling type of device for recovering oil and fume waste heat, and is particularly suitable for use in large-scale catering industries. Background technique [0002] The charm of Chinese catering comes from the unique cooking. The completion of cooking requires a series of operations with a fire source. A large amount of oil fume and tail heat are inevitably generated during the operation, which is of special significance for oil fume purification and tail heat recovery. [0003] The current fume purification and tail heat utilization of catering are far from reaching people's expectations. Generally, the range hood is directly discharged, causing environmental pollution and waste of heat. Especially in large-scale catering industries, it has a great impact on the surrounding environment and residents. Losing the heat carried in a large amount of oil fume obviou...

Problems solved by technology

[0003] At present, the oil fume purification and exhaust heat utilization of catering are far from meeting people's expectations. Generally, range hoods are discharged directly, causing environmental pollution and waste of heat energy, especially in large-scale catering industries, which have a great impact on the surrounding environment and residents. It consumes a lot of heat carried in the oil fume, which is obviously not in line with the energy-saving and emission-reduction policies advocated by our country at this stage

[0004] Although there are exhaust-type electrostatic lampblack purifiers on the market, they are difficult to popularize, mainly due to technical defects. After the lampblack purifier has been used for a period of time, the oil fume purification function will directly fail due to the accumulation of grease and humidity.
