Waste gas residual heat recycling device for organic silicon production technology

Abstract

The invention discloses a waste gas residual heat recycling device for an organic silicon production technology. The waste gas residual heat recycling device comprises a heat insulation box, a gathering box, a fixed frame, an outer chimney, a gas leakage pipe, an inner chimney, a spiral pipe, a water collector, a gas inlet pipe, a butt joint opening, a collection opening, short bulges, gaps and long bulges. The waste gas residual heat recycling device disclosed by the invention has the beneficial effects that the plurality of short bulges and long bulges are arranged on an inner wall of the inner chimney; the long and short bulges are symmetrically arranged; the gap with a Z-shaped structure is formed by each two groups of the long and short bulges; and waste gas passes through the gaps with the Z-shaped structure in a circulation process so that the retention time is prolonged. The spiral pipe matched with the distance between the inner wall of the outer chimney and an outer wall of the inner chimney is arranged between the inner wall of the outer chimney and the outer wall of the inner chimney; the spiral pipe is wound on the outer wall of the inner chimney and the butt joint opening of the spiral pipe is communicated with the gas leakage pipe; when excessive gas enters in one step, the gas is leaked; and meanwhile, the leaked gas is directly guided into the collection opening of the spiral pipe and the heat of the waste gas guided into the spiral pipe also can 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 the organic silicon production process, and belongs 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 is injected into the ...

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
