A catalytic purification device for organic waste gas

Abstract

The invention aims to provide an organic waste gas catalytic purification device. According to the technical scheme, the organic waste gas catalytic purification device is composed of a front processing device, a preprocessing output pipeline, an accident emptying valve, a flame arrester, a catalytic purification unit, a purified gas delivery pipeline, a volume adjusting valve, a draught fan and a purified gas exhaust pipeline. The front processing device is further provided with a preprocessed gas inlet. The accident emptying valve is further provided with an emptying pipe. The catalytic purification unit is further provided with a waste gas inlet, a waste gas delivery pipe, a heat exchanger, a heat exchange gas output pipe, a catalyst chamber, a catalytic gas output pipe, a purified gas output pipe and a purified gas output port. The device is an output mechanism, the low-temperature oxidation technology is adopted, organic waste gas is converted into carbon dioxide and water at low temperature under the action of a precious metal catalyst, the gas is purified, and power consumption is low; safety performance is improved; and the organic waste gas catalytic purification device is small in occupied area, high in purification efficiency and applicable to purification treatment of common pollutants discharged by various chemical industries.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a catalytic purification device for organic waste gas. Background technique [0002] Organic waste gas catalytic purification devices have been widely used in modern chemical and petrochemical production, and are also very effective in environmental engineering. The effect of treating organic waste gas and malodorous gas is also very ideal. Most organic waste gas treatment methods are They are quite different, and they all use the basic principle of using different organic substances to contact the surface of catalysts with different characteristics to undergo oxidation reactions, thereby reducing the required energy; reducing the operating temperature of the organic waste gas treatment equipment to the gas source temperature, so that the operating energy can be greatly saved. . However, these seemingly ideal treatment methods lack certain safety guarantees. Once many dust par...

Problems solved by technology

However, these seemingly ideal treatment methods lack certain safety guarantees. Once many dust particles remain in the gas to be purified, as well as the generation and existence of abnormal gases or flammable gases, if they are not handled properly, it will bring huge safety hazards to the entire purification mechanism. Hidden dangers, unimaginable consequences, and great harm to the safety of people's lives and property
