Heat energy recovery and environmental protection oil fume treatment device

Abstract

The invention discloses a thermal energy recovery and environment-friendly oil fume treatment device, which relates to the technical field of annealing furnace flue gas treatment, and includes an annealing furnace, a heat exchange tube, a cooler, a fan, a spray tower 1 and a spray tower 2, and above the annealing furnace A suction hood is provided, the inner wall of the heat exchange tube is provided with a steam generating mechanism, a plurality of said shunt pipes are sleeved on the inner wall of the shunt outlet, and the outer wall of the shunt sleeve is equipped with a heat dissipation assembly, and the outer wall of the cooler The socket has a water cooling mechanism. The present invention adds water to the inner wall of the ellipsoid water tank in advance through the return pipe, and the flue gas can heat the water on the inner wall of the ellipsoid water tank until it boils, and the high-pressure steam generated during boiling is supplied to the steam turbine through the steam pipe to drive the blades to rotate and drive the generator to generate electricity , so that the high-heat part in the flue gas is recovered first, and then enters the subsequent heat exchange device to realize the graded utilization of heat in the flue gas, realize the utilization of high temperature in the flue gas, good environmental protection, and improve the efficiency of heat collection .

Description

technical field [0001] The invention relates to the technical field of annealing furnace flue gas treatment, in particular to a thermal energy recovery and environment-friendly oil fume treatment device. Background technique [0002] Enterprises produce oily waste gas and non-methane total hydrocarbons in the production process of stainless steel annealing furnace. Because the waste gas has a certain impact on the surrounding environment and the personal safety of workers, in order to further do a good job in environmental protection and avoid affecting the factory area and the surrounding atmospheric environment, it is necessary To process the flue gas, it is also necessary to recover the heat energy in the flue gas. [0003] For the actual demand of flue gas treatment in the production of annealing furnace. [0004] (1) The Chinese utility model patent with the publication number CN211339632U ​​discloses a waste gas heat exchange device for a stainless steel belt annealin...
