Abstract
The utility model relates to an adsorption bed capable of controlling the output concentration. The adsorption bed comprises an adsorption bed body, wherein a desorption gas circulating outlet is formed in the adsorption bed body and 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 outlet of the desorption gas circulating fan is connected with a desorption gas circulating inlet in the adsorption bed through a pipeline. According to the adsorption bed, the technical assumption that gas in a desorption heating circulating system cannot be introduced into a catalysis bed until the concentration of industrial volatilizable organic pollutants in the gas reaches the self sustaining combustion concentration is realized, so that the preheated catalysis bed can quickly enter a self sustaining combustion state, and the heat feedback generated by catalysis combustion is enough to support the temperature needed by the catalysis bed; furthermore, a plate type heat exchanger can obtain enough heat, so as to provide energy for further desorption of the adsorption bed, preheating for desorption of the follower desorption bed is carried out, therefore a requirement on a design working condition is met, and an effective effect is achieved. Conditions are created for auxiliary heating and energy consumption reduction.
