Problems solved by technology

[0005] However, the problem in the background technology is that the amount of waste heat produced is far greater than the heat needed to recover and preheat the exhaust gas, so a large amount of exhaust heat is wasted

Abstract

The invention relates to an organic waste gas treatment and heat energy recycling system which comprises a draught fan, a heat-accumulated-type oxidation furnace with a combustion machine, a heat-resisting by-pass valve, a heat-resisting emergent exhaust air door, a hot oil exchanger, an evaporation boiler, a lithium bromide air conditioning unit and a chimney emission device, wherein the heat-accumulated-type oxidation furnace is connected with the by-pass valve, the hot oil exchanger and the evaporation boiler sequentially through a by-pass pipeline; the heat-accumulated-type oxidation furnace is connected with the chimney emission device through a main pipeline; and a high-temperature by-pass emergent exhaust air door is open so as to be connected with a chimney when the combustion chamber is overheated.

Description

technical field [0001] The invention relates to an organic waste gas treatment and heat energy recycling system. Background technique [0002] The process principle of the regenerative thermal oxidation furnace system (referred to as RTO) is: the hydrocarbon organic solvent is directly burned at a temperature of 760-850°C to make it completely thermally oxidized, and the residence time is 0.3-1.2 seconds (that is, the working state of the direct combustion RTO ). At this high temperature, the organic matter in the exhaust gas is oxidized and decomposed into carbon dioxide and water. [0003] The process flow of the conventional regenerative thermal oxidation furnace system, taking the rotary valve oxidation furnace as an example, the technical key of the regenerative thermal oxidation furnace is the use of a high-efficiency regenerative combustion system. The system consists of a combustion chamber, a regenerator bed divided into 12 grids (5 grids are the intake area, 5 gr...
