The invention relates to a preheat type catalytic combustion system for purifying volatile organic waste gas. The preheat type catalytic combustion system comprises a waste gas inlet, a dry filter, an active carbon adsorption device, heat exchangers, a catalytic combustion device, an air inlet, an air supplement port, a sampling port, temperature detectors, a fan and exhaust funnels. A gas collecting port is used for collecting the volatile organic waste gas, the volatile organic waste gas is filtered through the dry filter and then enters the active carbon adsorption device, and the standard waste gas is exhausted at a high altitude through the exhaust funnels by means of the exhaust fan after adsorption and purification. After the catalytic combustion system is preheated, volatile organic compounds adsorbed by active carbon are subjected to heating and desorption through hot air and then conveyed to a catalytic combustion chamber to be subjected to low-temperature catalytic oxidation decomposition, and the volatile organic compounds are decomposed into harmless substance such as CO2 and H2O after sufficient combustion and then exhausted at a high altitude. The system has the advantages that sufficient combustion of the volatile organic waste gas can be guaranteed, and concentration exceeding emission in the initial starting period is avoided; the concentration of the organic waste gas entering the catalytic combustion device can be controlled; potential safety hazards caused by excessively-high temperature of the active carbon adsorption device can be prevented.
