Energy-saving device for converting high-temperature flue gas of degreasing furnace into electric energy

Abstract

The invention discloses an energy-saving device for converting high-temperature flue gas of a degreasing furnace into electric energy. The device comprises a main machine body, wherein a filter cavityis arranged in the main machine body, a filter layer for filtering the flue gas is fixedly arranged on the inner wall of the filter cavity, a smoke exhaust pipe is arranged between the rear side of the filter cavity and the top side of a furnace cavity in a communicating mode, the top wall of the filter cavity is fixedly provided with a spray nozzle capable of spraying hot water into the filter cavity to filter the flue gas together with the filter layer, a pressure cavity is arranged on the right side of the filter cavity, and an air guide cavity is arranged between the pressure cavity and the filter cavity in a communicating mode. A turbine is driven to rotate by high-temperature steam obtained by filtering the high-temperature flue gas, then an electromagnetic coil is driven to rotateto generate electric energy which can be used for driving a power motor, the motor drives a transmission disc to rotate, and the effects of water heating and water spraying can be enhanced.

Description

technical field [0001] The invention relates to the technical field of converted electric energy utilization, in particular to an energy-saving device for converting electric energy from high-temperature flue gas of a degreasing furnace. Background technique [0002] With the rise of the powder metallurgy industry, more and more products are manufactured using this process, and the powder metallurgy process contains a degreasing process, which requires the use of a degreasing furnace. During the degreasing process, a large amount of high temperature smoke will be generated in the degreasing furnace. It not only pollutes the environment, but also wastes the energy of this part of the waste heat. Therefore, there is a need for a device that can effectively utilize this part of the waste heat, and can convert the waste heat into electrical energy. The device can filter the flue gas and improve the operating efficiency of the entire plant. SUMMARY OF THE INVENTION [0003] Th...

[0002] With the rise of the powder metallurgy industry, more and more products are manufactured using this process. The powder metallurgy process contains a degreasing process, which requires the use of a degreasing furnace. During the degreasing process, the degreasing furnace will produce a lot of high-temperature smoke. Gas, not only pollutes the environment, but also wastes the energy of this part of the waste heat. Therefore, there is a need for a device that can effectively use this part of the waste heat and convert the waste heat into electrical energy. The operating efficiency of the whole plant
