Exhaust gas waste heat recycling device used in organic silicon production process and application method

Abstract

The invention discloses an exhaust gas waste heat recycling device used in an organic silicon production process and an application method thereof. The device comprises a heat preservation box, a gathering box, a fixing frame, an outer chimney, a gas leakage pipe, an inner chimney, a spiral pipe, a catchment, a gas inlet pipe, an abutting joint port, a collection port, short protrusions, gaps andlong protrusions. The device has the advantages that a plurality of short protrusions and long protrusions are symmetrically arranged on the inner wall of the inner chimney, one gap of a Z-shaped structure is formed between every two short protrusions and long protrusions, exhaust gas passes through the gaps of the Z-shaped structures, and the standing time is prolonged. The spiral pipe matched with the inner chimney and the outer chimney in spacing distance is installed between the inner wall of the outer chimney and the outer wall of the inner chimney and winds the outer wall of the inner chimney, and the abutting joint port of the spiral pipe is communicated with the gas leakage pipe; when too much gas flows inside at a time, gas leakage occurs, and leaked gas is directly introduced into the collection port of the spiral pipe at this moment so that the heat of the waste gas introduced into the spiral pipe can also be recycled.

Description

technical field [0001] The invention relates to a waste gas waste heat recovery device, in particular to a waste gas waste heat recovery device used in an organic silicon production process and a use method thereof, belonging to the field of waste gas treatment. Background technique [0002] Organosilicon often undergoes a series of treatment steps during processing. Since organosilicon requires high-temperature heat treatment, a large amount of high-temperature exhaust gas is often generated during the heat treatment process. For these high-temperature exhaust gases, waste heat recovery devices are often used to recover the heat. The recovered heat can be used for secondary use in the silicone production process, thereby increasing the utilization rate of energy and saving costs. [0003] However, the existing waste gas and waste heat recovery devices used in the silicone production process still have certain defects when they are in use. When the high-temperature waste gas...

Problems solved by technology

[0003] However, the existing waste gas and waste heat recovery devices used in the silicone production process still have certain defects when they are in use. When the high-temperature waste gas is injected into the device during recovery, too much waste gas will often be injected at the same time, resulting in part of the waste gas. Not only will it easily cause accidental burns but also waste a lot of energy
