specific Embodiment

[0039] Such as figure 1 As shown, the pipeline connection and working process of the above treatment system can be:

[0040]The high-concentration exhaust gas directly enters the heat-exchanging CO treatment device through the pipeline, and the exhaust gas at the inlet is heated up by the multi-stage preheating heat exchanger inside the CO device to reach the optimal catalytic reaction temperature. The high-temperature gas after the catalytic oxidation reaction is used as the heat source of the heat exchanger to preheat the gas at the inlet to achieve heat recovery.

[0041] Driven by the No. 1 negative pressure fan connected to the gas outlet, the heat exchange CO starts to work and discharges high-temperature gas. The outlet of No. 1 fan is divided into three ways: the first way is connected to the inlet of the water cooler, and the gas entering the molecular sieve adsorption and desorption device of the back-end processing module is cooled by water to ensure the normal ads...

Abstract

The invention discloses a treatment system for high-concentration organic waste gas and relates to the technical field of pharmaceutical industry waste gas treatment. The treatment system comprises a heat exchanging type CO device, a water cooler and a molecular sieve adsorption and desorption device and is characterized in that the waste gas directly enters the heat exchanging type CO device through a pipeline, oxidization decomposition of the high-concentration organic waste gas is performed, and the decomposed high-temperature gas enters the molecular sieve adsorption and desorption device through the water cooler and is directly discharged after adsorption; molecular sieve desorption air uses the high-temperature gas of the gas outlet of the heat exchanging type CO device, desorption discharge gas returns to the front end of the heat exchanging type CO device, and oxidation treatment is continued to form a local closed-loop state; molecular sieve cooling air uses normal-temperature air, and cooled gas is also conveyed to the front end of the heat exchanging type CO device. The whole treatment system is high in flexibility, excellent in purification effect, capable of sufficiently utilizing heat, capable of achieving low-standard emission and optimal in equipment investment during the treatment of the high-concentration organic waste gas.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment in the pharmaceutical industry, in particular to a high-concentration organic waste gas treatment system. Background technique [0002] my country's pharmaceutical industry is a major environmental polluter. The exhaust gas has complex components, serious pollution hazards, and irregular exhaust emissions. Therefore, it is particularly critical to develop an adaptable exhaust gas treatment system in the field of pharmaceutical industry exhaust gas treatment. [0003] In recent years, molecular sieve adsorption concentration devices and catalytic oxidation devices have been favored by the waste gas treatment industry. The principle of molecular sieve adsorption and concentration is: using adsorption-high-temperature desorption concentration-cooling and re-adsorption, three continuous temperature-swing adsorption and desorption programmed processes, so that low-concentration organic wast...
