Problems solved by technology

Due to the low concentration of VOCs in the gas in the initial stage and the final stage, the combustion heat generated cannot meet the "self-sustaining" operation requirements of the system. The maintenance of the temperature of the catalytic bed and the additional heat of desorption of the adsorption bed can only be supplemented by an auxiliary heat source for a long time, thus causing the system to run. The consumption is very high. In addition, in some paint spraying workshops, industrial volatile organic pollutants are often mixed with paint mist. When the adsorption bed is adsorbed, the paint mist will adhere to the adsorption material in the adsorption bed, causing the adsorption bed to not work normally and reducing the The efficiency of purification treatment increases the cost of purification treatment and affects normal production

Abstract

The invention relates to an output-concentration-controllable adsorption system special for a painting workshop. The adsorption system comprises a spraying filter device and an adsorption bed with a controllable output concentration, wherein the spraying filter device comprises a tower body; one side of an air outlet of the tower body is fixedly provided with a filter; an air inlet of the filter is communicated with an air outlet of the tower body; the filter is internally provided with a particle filter layer horizontally; a desorption gas circulation outlet is formed in the adsorption bed with the controllable output concentration; the desorption gas circulation outlet is connected with an air inlet of an electric heater through a pipeline; an air outlet of the electric heater is connected with an air inlet of a desorption gas circulating fan through a pipeline; an air outlet of the desorption gas circulating fan is connected with a desorption gas circulation inlet in the adsorption bed through a pipeline. The adsorption system outputs industrial volatile organic pollutants with the controllable concentration, provides a guarantee for sustainable energy conservation, and can effectively separate oil paint fog from the industrial volatile organic pollutants, thus improving the processing efficiency of the industrial volatile organic pollutants and guaranteeing the regular production.

Description

technical field [0001] The invention belongs to the field of adsorption systems, in particular to an adsorption system specially used for controllable output concentration of spraying workshops. Background technique [0002] Among the PM2.5, the most harmful to people's health is industrial volatile organic pollutants. In the prior art, the catalytic bed combustion method is mainly used for industrial volatile organic pollutants, and the industrial volatile organic pollutants are adsorbed and concentrated by the adsorption bed. After that, desorption is carried out into the catalytic bed for combustion, and the industrial volatile organic pollutants are converted into carbon dioxide and water. The temperature of the gas after combustion is relatively high. The heat of catalytic combustion is recovered through the plate heat exchanger and used to remove additional heat and maintain catalysis. The process temperature requirements of the system. The circulation system is conne...
