Description

Purifier based on heat accumulation formula catalytic combustion

Technical Field

The utility model relates to a waste gas purification device, specific purifier based on heat accumulation formula catalytic combustion that says so.

Background

At present, gaseous organic pollutants are various in types, main waste gas is benzene series, VOCs and the like, a production workshop can generate a large amount of organic waste gas in the production process, the waste gas is emitted to the workshop to pollute the environment of the workshop, and a human body inhales for a long time to damage a central nervous system and seriously damage the physical health of workers. The treatment methods adopted are various, and the common treatment methods are mainly an activated carbon adsorption method and a heat accumulating type incineration method. The traditional activated carbon that uses adsorbs to get rid of, adsorbs saturated activated carbon can regeneration, however, can thoroughly saturate unable regeneration through the reuse back activated carbon, and these activated carbons can cause certain harm to the environment as hazardous waste. Meanwhile, the treatment, regeneration and replacement of the activated carbon can generate large operation cost, and the waste gas treatment is in a stagnation state in the processes, so that the waste gas treatment efficiency is not high enough, the reaction effect of frequently replacing the activated carbon is not stable enough, and furthermore, the activated carbon treatment equipment needs certain contact time, and the atmosphere is polluted when the carbon layer penetrates through the activated carbon treatment equipment. For this purpose, a process for purifying organic waste gases has appeared in the line, comprising the following steps: (1) organic waste gas enters the lower part of the reaction container through an input pipeline, meanwhile, the free radical generating system works to generate free radicals, and the generated free radicals are mixed with the organic waste gas in the input pipeline through a communicating pipeline; (2) the mixed organic waste gas and free radicals pass through the reaction wall; (3) the reaction liquid is sprayed out by the reaction liquid spray head, and the reaction liquid descends to the reaction wall and reacts with the organic waste gas and the free radicals after rising and mixing under the action of the catalyst to realize purification; (4) under the action of the fan, the purified organic waste gas is discharged from the output pipeline, and the reaction liquid falls to the bottom of the reaction container and is recycled through the reaction liquid pipeline. Although the defect that traditional active carbon adsorption got rid of has been solved to a certain extent to this patent, still there is the catalyst use amount big, and catalytic efficiency is low, and the power consumption is high, and purification treatment is inefficient, and the treatment effect is unstable, and equipment life is short and so on defect. The existing heat accumulating type incineration method is used for waste gas purification treatment and needs to be carried out at the high temperature of over 800 ℃, the high temperature needs much heat and high energy consumption, and secondary pollutants of N0X are generated in the treatment process. RC0, namely Regenerative Catalytic Oxidation (RCO), is one of combustion processing technologies, and is developed into modern advanced organic waste gas processing technology by adopting a series of energy-saving designs and material selections on the basis of Catalytic oxidation (Catalytic 0 xidizecros) and Regenerative Thermal0 xidizers (RTO).

In conclusion, the regenerative catalytic oxidation method has more advantages in waste gas treatment and purification, but the prior industry lacks a corresponding device structure which is mature in application.
