Continuous heat accumulating type VOC (Volatile Organic Compounds) organic waste gas incinerator

Abstract

The invention relates to a continuous heat accumulating type VOC (Volatile Organic Compounds) organic waste gas incinerator. The continuous heat accumulating type VOC organic waste gas incinerator comprises an incineration chamber, a combustor, a heat accumulating body, a fixed cover, an outer frame, a heat accumulating chamber rotor, a large plane slewing bearing, a fixed seat, a motor speed reducer group and the like. VOC organic waste gas is guided into the incinerator through a fixed seat connector at the bottom, goes upwards to enter the rotor which is loaded with a honeycomb heat accumulating body, passes through honeycomb ceramic, is heated to about 800 DEG C, is oxidized at a high temperature gradually, and enters into the fixed incineration chamber in the upper part; under the heating of the combustion stabilizing combustor of the incineration chamber, the temperature of the incineration chamber is risen to about 850 DEG C; the VOC organic waste gas is completely oxidized and damaged; formed high-temperature flue gas goes downward, enters a flue gas exothermic side of the rotor, passes through the honeycomb ceramic to release heat and cool, and is led out from the fixed seat flue gas connector at the bottom. The continuous heat accumulating type VOC organic waste gas incinerator is suitable for incineration treatment of the VOC organic waste gas; waste heat can be fully recycled; the operating condition is stable; a gas flowing direction and a temperature field are stable; the treatment is thorough and reliable.

Description

technical field [0001] The invention relates to incineration treatment equipment, in particular to an incinerator suitable for treating VOC organic waste gas. Background technique [0002] VOC organic waste gas incineration treatment has a history of more than 100 years, from the initial direct combustion method to later thermal incineration, closed combustion, heat exchange thermal incineration, and then to regenerative incineration (RTO system) with high heat recovery. The RTO system adopts reversing heat storage incineration technology, which has developed from the initial two regenerators to the current five regenerators. Although it can effectively destroy VOC organic waste gas and has a high removal efficiency, due to the reversing control The system is relatively complicated, and the gas flow direction in the regenerator is always changing when the valve plate is switched, and the pressure also fluctuates. In addition, in a reversing cycle, the heat absorption and exc...

The RTO system adopts reversing heat storage incineration technology, which has developed from the initial two regenerators to the current five regenerators. Although it can effectively destroy VOC organic waste gas and has a high removal efficiency, due to the reversing control The system is relatively complicated, and the gas flow direction in the regenerator is always changing when the valve plate is switched, and the pressure also fluctuates. In addition, in a reversing cycle, the heat absorption and exchange of the regenerator over time There is also a certain periodic change in the heat, and the temperature changes in the heat storage chamber are not uniform, so the removal rate cannot be further improved and the energy consumption can be reduced.

[0003] Multi-regenerator rotary reversing RTO, the reversing of multiple regenerators is controlled by a rotary valve, and multiple groups of regenerators combined in a cylindrical shell structure also have pressure, temperature, gas flow direction, and flame direction The characteristics of periodic changes, and the structure of the rotary valve is complex, difficult to maintain and short in life
